Abstract<br />

In this paper we investigate in the Italian institutional context the effect<br />

of the attended university on earnings and employment prospects three years<br />

after graduation. We find that <strong>Alma</strong> <strong>Mater</strong> <strong>matter</strong>s significantly for the early<br />

labour market performance of Italian graduates. In particular, graduates <strong>from</strong><br />

universities located in the Northern part of the country experience three years<br />

after graduation significantly higher employment probabilities but only slightly<br />

higher nominal earnings than graduates <strong>from</strong> Southern universities. We also<br />

find that the mobility of Italian students across universities – and particularly<br />

<strong>from</strong> the South to the North - is limited. There is little support, however, to the<br />

view that mobility is hampered by liquidity constraints.<br />

Introduction<br />

<strong>Does</strong> the attended college affect the earnings and employment prospects<br />

of graduates? This question is particularly important for the households<br />

sending their offspring to college and paying part of the cost, and for the<br />

government, which in a number of countries runs most universities and needs<br />

to know whether and why some institutions may be delivering better outcomes<br />

than others.<br />

Spurred by the interest on the quality of education, a recent literature<br />

has investigated the labour market effects of college quality, mainly but not<br />

exclusively in the US. Black and Smith, 2003, and Brand and Halaby, 2003,<br />

review the key contributions. The main focus in this literature has been so far<br />

on comparing elite versus non – elite colleges, and the degree of selectivity<br />

has been measured either with the average SAT score of the incoming<br />

freshmen – in the US – or with the average A-level score of the intake of<br />

students – in the UK (see Chevalier and Gonlon, 2003). The basic finding of<br />

this literature is that college quality <strong>matter</strong>s for labour market outcomes.<br />

In this paper we investigate in the Italian institutional context the effect<br />

of the attended university on earnings and employment prospects three years<br />

after graduation. Since we cannot measure unambiguously selectivity, we<br />

focus instead on the location of the college, on the public/private divide and on<br />

observable measures of college quality. We find that <strong>Alma</strong> <strong>Mater</strong> <strong>matter</strong>s<br />

significantly for the early labour market performance of Italian graduates. In<br />

particular, graduates <strong>from</strong> universities located in the more developed Northern<br />

part of the country experience three years after graduation significantly higher<br />

employment probabilities but only slightly higher nominal earnings than<br />

graduates <strong>from</strong> Southern universities.<br />

We also find that the mobility of Italian students across universities –<br />

and particularly <strong>from</strong> the under-developed South to the more developed North<br />

- is limited. There is little support, however, to the view that mobility is<br />

hampered by liquidity constraints. Alternative explanations include regional<br />

price differentials, which reduce the earnings gap between the North and the<br />

1


South – and can even turn the gap into an advantage, and the possibility that<br />

uncovered differences are temporary. The finding that the expected returns to<br />

college are not significantly higher for the graduates of Northern universities<br />

combines with the higher cost of living, opportunity costs and tuition fees in<br />

the North to explain why so many Southern students still prefer to enrol in the<br />

South.<br />

We also find that going to a private university <strong>matter</strong>s especially for the<br />

probability of finding a job, but not always in a positive way. Heterogeneity in<br />

early labour market returns spread <strong>from</strong> public to private universities. When<br />

the attended private college yields negative employment and earnings gains,<br />

the question arises why households should enrol their offspring in such<br />

institutions at a higher tuition fees than in public universities. The natural<br />

explanation is that these losses are temporary, and turn into gains as labour<br />

market experience increases. Religious and cultural reasons, access to<br />

networks and leisure are additional and not necessarily mutually exclusive<br />

explanations.<br />

Available indicators of college quality explain some but not all the<br />

difference between private and public tertiary education. There is evidence that<br />

the pupil – teacher ratio, the size of the university – in terms of the number of<br />

enrolled students - and the proportion of female teachers affect in a<br />

statistically significant way either wages or employment or both. The location<br />

of the college also <strong>matter</strong>s, as universities located in the South usually deliver<br />

inferior outcomes.<br />

The policy implications clearly depend on whether the effects of<br />

measured college quality three years after graduation persist over time. While<br />

limited mobility <strong>from</strong> lower to higher performing universities suggests that<br />

some of these effects are temporary, better data than those available are<br />

required to answer this key question. In particular, it would be critical to re-<br />

interview graduates at regular times during their career, as in the UK Graduate<br />

Cohort Study, which repeats interviews three, six and eleven years since<br />

graduation.<br />

Assuming that the uncovered effects are at least in part permanent, they<br />

suggest that policies favouring the diffusion of universities in the Italian<br />

territory need not be farsighted, as employment probabilities are significantly<br />

higher with larger – and older - institutions, possibly because of their<br />

entrenched reputation in the labour market. Policies promoting equal<br />

opportunity and a higher percentage of female professors have ambiguous<br />

labour market effects, negative on male graduates and positive on female<br />

graduates. Finally, and conditional on measured quality and on local labour<br />

market effects, Southern universities perform less satisfactorily than the<br />

universities in the rest of the country. Understanding why this is the case is an<br />

important area of policy evaluation.<br />

The paper is organized as follows. Section 1 provides some institutional<br />

background; Section 2 discusses the empirical approach; Section 3 introduces<br />

the data and Section 4 presents the results. Conclusions follow.<br />

1. Institutional background<br />

By international standards, Italy has 10 graduates out of 100 individuals<br />

aged 25 to 64, significantly lower than the OECD average of 15. Relatively low<br />

attainment is matched by a relatively low rate of return, 6.5 percent per year<br />

of college education, compared to 11.8 percent in the main developed<br />

economies (see OECD, 2003). Assuming a downward sloping demand for<br />

college education and an upward sloping supply, the combination of low<br />

attainment and low returns suggests that the relative demand for college<br />

graduates in Italy is relatively low by international standards 1 .<br />

Reasons for relative low demand could be that the Italian industrial<br />

structure is biased against higher education, or that the perceived quality of<br />

tertiary education is low, or both. According to the OECD, Italy spends less<br />

than the major developed economies for tertiary education. In the year 2000,<br />

the average expenditure per student was 8065 US dollars, compared to 8373<br />

dollars in France, 10898 dollars in Germany, 9657 dollars in the UK and 20358<br />

dollars in the US. Low expenditure is partly due to the fact that average pay in<br />

universities is low and partly to a higher than average students to teacher ratio<br />

(22.4 compared to the OECD average of 16.5 2 ). Moreover, Italy has a<br />

relatively low share of private universities, which enrol only 6.4 percent of<br />

college students, compared to 12 in the OECD average.<br />

Only 10.9 percent of the budget comes <strong>from</strong> tuition fees. See Perotti,<br />

2002, for a very good discussion of the funding of Italian universities.<br />

2. Empirical strategy<br />

The recent literature on the estimation of college quality (wage-) effects<br />

highlights a few issues inherent to such exercise. Specifically, Black and Smith<br />

(2003) discuss the pitfalls that a standard log-wage regression could lead to,<br />

and how matching estimators can solve/mitigate those issues. First, there is<br />

the issue of selection on unobservables, omitted variable bias in the language<br />

of linear regression: as long as factors that influence both treatment receipt (in<br />

their case college quality) and the outcome (earnings) are omitted <strong>from</strong> the<br />

estimating model, resulting effects are biased and inconsistent. Second, there<br />

is the issue of common support, multicollinearity in the language of linear<br />

regression: in order for the effect to be identified the variability of the<br />

treatment over the sample must not be already captured by other covariates in<br />

the model, which is achieved when there are cells defined by the intersection<br />

of the covariates in which both treated and non-treated individuals are<br />

observed. Black and Smith stress an important implication of this property: the<br />

effect estimated by a linear regression is identified non-parametrically only in<br />

the common support, while outside the common support it is a parametric<br />

projection of the effect estimated using observations in common support.<br />

Thirdly, and finally, they point to the issue of linear conditioning on<br />

observables, functional form misspecification in the language of linear<br />

regression: even if all the relevant personal attributes are controlled for, an<br />

omitted variable bias could emerge if they enter the estimating equation with<br />

an inappropriate functional form. The Black and Smith approach is to resort to<br />

2 Notice that Italy has a very low ratio in primary and secondary education, as discussed in detail by Brunello and<br />

Checchi, 2004. Perotti, 2002, contains an interesting comparison between the Italian and the British higher education<br />

systems.<br />

a (propensity score) matching estimator. As explained in their paper, such an<br />

approach: a) assumes that there is no selection on unobservables problem; b)<br />

‘…does not solve the support problem… (page 5)’; and c) solves the linear<br />

conditioning issue, since rather than assuming that the expected value of the<br />

outcome conditional on the observables is a linear function of the observables,<br />

makes a fully non-parametric comparison of mean outcomes between treated<br />

and non-treated individuals in the common support.<br />

In this paper we take a different estimating approach, which we illustrate<br />

by focussing on wages as the outcome of interest (we also study employment<br />

probabilities and we detail later our methodology in that case). Let<br />

wi=αw+ΣfΣcd cf iθ cf +xi’γw+ui (1)<br />

be the log-monthly wage for individual i (i=1…N), a linear function of the<br />

college-faculty cluster <strong>from</strong> which she graduated (d cf i) and observable<br />

attributes (xi). The vector of observables includes controls for gender, region of<br />

employment, labour market experience parental background in terms of<br />

occupation and education, the final graduation mark, the type of high school<br />

attended (whether generalist or technical/professional) and the marks reported<br />

in the high school graduation exam. Given the inclusion of detailed parental<br />

background, these latter variable are likely to proxy the impact of ability. Most<br />

importantly, we allow for interactions between parental education and<br />

occupations, on the one hand, and marks and school types, on the other.<br />

Therefore, we allow all regressors related to personal attributes to enter the<br />

model non-linearly, which might result in an attenuation of the risks of<br />

misspecifying functional form. As for the first problem discussed in Black and<br />

Smith (2003), we assume, as they do, selection on observables, and specify a<br />

rather extended list of observables. Finally, we can not identify effects on<br />

college faculty dummies for which there is no common support.<br />

Regression (1) serves as the first step in our procedure and allows us to<br />

predict log-monthly earnings by college/faculty clusters. In the second step,<br />

we take an approach a-là- Card and Krueger (1991) and analyse the<br />

5


determinants of college/faculty wage effects. Specifically, let q cf be the<br />

estimate of θ cf <strong>from</strong> (1). Let q be the vector stacking these estimates: they<br />

are the mean wages by college-faculty clusters. In the second step of our<br />

procedure, we estimate the effect of several dimension of college quality by<br />

regressing estimated wage effects on college quality measures derived <strong>from</strong><br />

published sources or other measures of college heterogeneity, plus college and<br />

faculty fixed effects. We employ a Weighted Least Squares, using weights<br />

proportional to the (inverse) of var(q) to account for the fact that our<br />

dependent variables are estimates <strong>from</strong> the first stage.<br />

As we said above, we also analyse the impact of <strong>Alma</strong> <strong>Mater</strong> on<br />

employment probabilities. In that case, equation (1) is substituted by a probit<br />

equation, the dependent variable scoring one for the employed and zero<br />

otherwise. 3 From such a probit equation we can estimate the employment<br />

probability (and its variance) for each college/faculty cluster, which we then<br />

employ as dependent variable (and weight) in the second step regression.<br />

3. The Data<br />

The National Statistical Office (ISTAT) carries out on a regular basis a<br />

statistical survey – the “Indagine statistica sull’inserimento professionale dei<br />

laureati” - on the transition <strong>from</strong> college to work of a representative sample of<br />

Italian graduates. The last available wave interviews individuals who graduated<br />

in 1998 three years after completion of the degree, in 2001. The survey covers<br />

school curriculum, labour market experience in the three years after<br />

graduation, job search activities, household and individual information. We<br />

match these data with the information on college quality disaggregated by field<br />

of study and provided by ISTAT for the academic year 1996-7 4 .<br />

We focus our analysis on the effects on the college on the probability of<br />

being employed three years after graduation and on net monthly earnings in<br />

the job held at the time of the interview. Employment in the survey includes all<br />

In this case, the conditioning set excludes labour market experience, while regions of work are substituted by regions<br />

of birth.<br />

paid jobs, including apprenticeship contracts 5 . About 4 percent of the currently<br />

employed are on a training contract – which includes post-graduate education.<br />

This percentage raises to close to 44 percent among those not currently<br />

working. Monthly earnings in 2001 are in euros and net of taxes and social<br />

security contributions 6 . Average earnings in the sample are 1140,1 euros per<br />

month, with a standard deviation of 422.8, and range <strong>from</strong> a minimum of<br />

103,2 € to a maximum of 4389,8 €. On the other hand, the average probability<br />

of being employed three years after graduation is 0.664, with a standard<br />

deviation of 0.472.<br />

Table 1 shows average pay and employment probability by gender, type<br />

of college – public or private – and area where the college is located. On<br />

average, male graduates earn about 25 percent more than females, and are<br />

more likely to have a paid job three years after graduation. Having graduated<br />

<strong>from</strong> a private college yields a close to 10 percent wage premium, and a close<br />

to 20 percent premium in the probability of employment. Finally, graduation<br />

<strong>from</strong> a college located in the Northwest yields a 20 percent wage premium and<br />

a close to 50 percent higher employment probability than having graduated in<br />

a Southern college. The regional wage premium falls considerably <strong>from</strong> 20 to<br />

8.3 if we compare individuals who graduated <strong>from</strong> a college in the Northwest<br />

and work in the same area with individuals who graduated in the South but<br />

work in the Northwest.<br />

5 The relevant question is: “Are you now – at the time of the survey – on a paid job? “ Only a very small minority of<br />

those not currently employed were employed in the week before the interview. Since we do not have information on<br />

wages, we drop these individuals <strong>from</strong> the sample.<br />

computations based on continuous variables were carried out at the ADELE ISTAT laboratory in Rome.<br />

College located in Northeast Italy 1124,7 0,733<br />

College located in Central Italy 1121,0 0,631<br />

College located in Southern Italy 1054,6 0,513<br />

Needless to say, these averages are affected by individual<br />

characteristics, the college and the field of study. Table 2 reports average<br />

earnings and employment probabilities in 16 fields of study, which correspond<br />

to different faculties.<br />

Average earnings are highest for graduates in Medicine, who face on the<br />

other hand the lowest employment probability, and lowest for graduates in<br />

Foreign Languages. Figure 1 and Figure 2 show that both earnings and<br />

employment probabilities vary substantially within each field of study by<br />

college. The within-field of study variation in earnings – measured by the<br />

coefficient of variation - is highest for the graduates in Medicine, Sociology and<br />

Statistics. In the former field, a graduate <strong>from</strong> Verona and Padova earn per<br />

month close to 100 percent more than a graduate <strong>from</strong> Pisa and L’Aquila.<br />

In the latter field, a graduate <strong>from</strong> Florence earns on average 84 percent<br />

more per month than a graduate <strong>from</strong> Messina. Moreover, the average<br />

monthly earnings of a graduate in Economics <strong>from</strong> Bocconi University, a<br />

private institution, are about 60 percent higher than the earnings of a graduate<br />

in the same field <strong>from</strong> the University of Benevento, at the bottom of the list.<br />

Turning to employment probabilities, it is always the case that these are<br />

lowest for graduates of Southern colleges, independently of whether they look<br />

for a job in the North or in the South of the country. For example, a graduate<br />

in Engineering <strong>from</strong> the University of Trieste has a probability of employment<br />

after three years close to 1, compared to less than 0.6 for a graduate <strong>from</strong><br />

Potenza, in the deep South.<br />

Next, we compare the average earnings and employment probabilities of<br />

graduates of public and private colleges – by restricting attention to<br />

economics, which include a few private universities. Figures 3 and 4 show that<br />

private colleges do better on average than public colleges, both for earnings<br />

and for employment. Some private universities, however, perform worse in<br />

terms of earnings and at least as well in terms of employment as top public<br />

institutions.<br />

but less than the graduates of Rome Tor Vergata, a public institution located in<br />

Both private and public colleges generate heterogeneous outcomes in the<br />

labour market. Part of this heterogeneity could fade away over time, as<br />

graduates settle in their jobs, but part could depend on measurable differences<br />

in inputs and outputs. Table 3 illustrates some of these differences, separately<br />

for public and private colleges.<br />

Table 3. Differences in inputs and outputs, by type of college<br />

Percentage of graduates over enrolled students 7.54 11.76<br />

Note: the year of establishment is coded as 1800 if the college was established in 1800 or before.<br />

The table shows that private universities tend to be younger, smaller,<br />

and have a significantly lower ratio of students to teachers. While the average<br />

age of professors is about the same, the percentage of female professors is<br />

slightly lower, and the percentage of graduates over enrolled students<br />

significantly higher. The Data Appendix shows how these indicators vary across<br />

colleges and fields of study.<br />

The list of indicators in Table 3 cannot be considered as exhaustive. An<br />

indicator that is missing in our data is the average peer effect. This is an<br />

important measure if we believe, as Epple and Romano, 1998, that school<br />

quality critically depends on the average quality of enrolled students. Another<br />

missing indicator is a measure of network effects, which might play an<br />

important role if private colleges provide access to better networks, and if<br />

these networks are important in the search of a good job, as suggested for<br />

Italy by Pellizzari, 2003. Finally, we miss information of teacher quality. The<br />

recent literature on school quality (see Hanushek, 2002, for a survey), clearly<br />

emphasizes this variable as key to explain school performance.


4. Results<br />

In the first step regressions (REPORT IN THE APPENDIX), we fit<br />

individual earnings and employment probabilities separately by gender on 411<br />

college by field of study dummies, individual experience, experience squared,<br />

number of siblings, cohort of birth dummies, type of job (whether the current<br />

job is part time or full time), dummies for additional years in college after the<br />

required years, dummies for the region of current residence, individual<br />

graduation marks – relative to the highest attainable mark – type of school<br />

before college, graduating marks in upper secondary education, family<br />

background – measured by the education and occupation of both parents when<br />

the individual was 14 years of age – and interactions between education before<br />

college and family background. The maintained hypothesis is that performance<br />

at school before college, family background and their interactions fully capture<br />

unobserved individual ability, which affects earnings as well as selection into<br />

employment.<br />

4.1 College effects on wages and employment<br />

We interpret the estimated coefficients of the 411 dummies as the net<br />

impact of college and field of study on individual earnings and employment<br />

three years after graduation. Under our maintained assumption, these<br />

estimates are consistent. We distinguish the net <strong>from</strong> the gross impact,<br />

because the college and field of study can affect some of the controls, such as<br />

labour market experience, performance in college, type of job, region of<br />

residence and actual time to complete the degree. We also compute the gross<br />

impact of college and field by re-estimating the first step regressions after<br />

excluding such controls. To save space, we present some results based on the<br />

gross effect in the Appendix.<br />

The region of residence three years after graduation does not necessarily<br />

coincide with the region where the college was located, as individuals migrate<br />

to the areas of the country where they can locate better matches. Table 4<br />

illustrates the mobility flows across the four macro areas of the country. As<br />

13


expected, individuals completing a degree in the Centre or in the South are<br />

more likely than individuals in the North to relocate and work in another<br />

macro-area, typically the North West, where many college jobs are located. In<br />

spite of these mobility flows, the percentage of individuals who currently reside<br />

in the same area where they went to college is at least equal to three quarters<br />

of the population of graduates.<br />

College South 9.17 3.34 6.87 80.62<br />

Note: the numbers in the table are percentages, which add up to 100 by row.<br />

We disentangle the contributions of the field of study and the university<br />

to the wage and employment effects by regressing the estimated net effects<br />

on separate field of study and college dummies. In order to have sufficient<br />

observations for each university, we restrict our attention to the institutions<br />

with at least five faculties. The college dummies in these regressions measure<br />

the effect of each university on earnings and employment, conditional on the<br />

field of choice and on the individual effects controlled in the first stage. As<br />

shown in Figures 5 and 6, the variation of college effects is substantial, both<br />

for wages and for employment.<br />

Consider first wages. The difference between the highest and the lowest<br />

college effect is higher than 25 percent for both genders. For instance, male


graduates <strong>from</strong> the University of Trieste, in the North-East, earn 53 percent<br />

more on their current job three years after college than graduates <strong>from</strong><br />

Cosenza, in the South of the country. Female graduates <strong>from</strong> Torino, in the<br />

North West, earn about 29 percent more than graduates <strong>from</strong> Ferrara, in the<br />

North-East. There is also a significant difference in the earnings of graduates<br />

<strong>from</strong> the largest universities in Rome – La Sapienza and Tor Vergata – and the<br />

largest colleges in Milan – Statale and Cattolica. For instance, male graduates<br />

<strong>from</strong> La Sapienza earn three years after graduation 16 percent less than male<br />

graduates <strong>from</strong> Statale.<br />

If we use the mean wage effects for males and females to divide the<br />

diagram in four quadrants, we discover some interesting heterogeneity. While<br />

Northern colleges tend to perform better than Southern colleges, there are<br />

exceptions: Ferrara and Modena, for instance, do well for males but poorly for<br />

females. On the other hand, Lecce is located in the outward quadrant, above<br />

both means. On average, Northern wage effects are 6.7 and 3.4 percent<br />

higher that Southern wage effects for maels and females respectively.<br />

Turning to employment probabilities three years after college, the<br />

difference across universities is large, with graduates <strong>from</strong> Turin enjoying a<br />

probability higher than 70 percent and graduates <strong>from</strong> Messina experiencing<br />

probabilities lower than 50 percent, independently of the region of current<br />

residence. Compared to earnings, the difference in employment probabilities<br />

for the graduates of the large universities located in Rome and Milan is<br />

negligible for males but large for females. Furthermore, the segregation of<br />

Southern colleges in the lowest quadrant near the origin is much more marked<br />

than in the case of wages. On average, Northern employment effects are 25<br />

and 32 percent higher that Southern wage effects for maels and females<br />

respectively.<br />

Figures 7 and 8 plot wage and employment effects by gender. A natural<br />

reading here is that the points in the figures lie on different demand curves,<br />

which express the labour market trade-off between earnings and employment<br />

probabilities.<br />

Focusing on males, the wage and employment effects in Figure 7 are<br />

delimited by a demand curve close to the origin and connecting the Southern<br />

colleges of Messina, Palermo, Catania, Cagliari and Cosenza, and by an


outward demand curve connecting several universities of the North, Trento,<br />

Torino, Milano Catholic, Modena, Pavia and one in the Centre, Florence. A<br />

similar reading is possible for female graduates in Figure 8. If we rank<br />

universities on the basis of the demand curve they lie upon, the North-South<br />

divide emerges quite clearly. This divide is driven by employment probabilities<br />

rather than by wages.<br />

If students were perfectly mobile across universities, and the private<br />

costs of graduating <strong>from</strong> each institution were homogeneous across the<br />

country, we would expect these large differences in college – specific labour<br />

market returns to be washed away. Mobility of university students, however, is<br />

limited. Our survey provides information both on the region of residence before<br />

going to college and on the region where the college is located. As shown by<br />

Table 5, there is very little mobility across macro-regions, not only in the<br />

Northern and Central areas, where many high performing universities are<br />

located, but also in the South, where universities are among the worst<br />

performing in the sample. More in detail, students who resided in the South<br />

before college either remain there for college (73.5%) or move to the nearby<br />

Centre (18.8%): less than 8% move to the North 7 .<br />

Table 5. Mobility flows among the four macro areas of Italy, before college and<br />

during college<br />

Before College Centre 0.88 4.79 93.69 0.64<br />

Before College South 3.56 4.04 18.86 73.54<br />

Note: the numbers in the table are percentages, which add up to 100 by row.<br />

These number cover, however, some interesting heterogeneity within<br />

macro-areas. In the South, for instance, the percentage of students remaining<br />

in their region to go to college is higher than 80 percent in Sicily and Sardinia<br />

and close to 40 percent in Calabria.<br />

7 The differences in performance across universities are net of local labour market effects, because we control for region<br />

of residence dummies in the first step when estimating net wages and employment effects.<br />

18


How do we explain the limited mobility flows between macro-areas? One<br />

natural possibility is that low mobility depends on family background and on<br />

liquidity constraints. According to this story, the internal rate of return of<br />

graduating <strong>from</strong> a Northern college is higher than in the South, but the higher<br />

costs prevent many Southerners <strong>from</strong> enrolling in the North. Studying in a<br />

university located in the North is likely to be expensive for a Southern student<br />

for a number of reasons. First, tuition is higher. Even though fees are not high<br />

by international standards, Northern colleges have used to a much larger<br />

extent than other universities in the country the opportunity to raise tuition in<br />

the second part of the 1990s above the centrally established ceiling (Law<br />

122/94). This and the endogenous selection of students to college have implied<br />

that average tuition in 1995 was about 50 percent higher in Northern than in<br />

Southern public universities – 511 € versus 326 € at current prices (see<br />

Silvestri et al, 1996). Second, both opportunity and living costs – including<br />

housing – are higher in the North. Third and last, income support provided by<br />

the national and local government is considered to be largely inadequate to<br />

eliminate liquidity constraints, as documented by Silvestri et al, 1996. [NON<br />

SAREBBE MALE AVERE QUALCHE DATO SUI COSTI DI VIVERE FUORI CASA<br />

ALL’UNIVERSITA]<br />

If liquidity constraints had played a significant role in hampering the<br />

mobility of students <strong>from</strong> the South to the North, we would expect to find that<br />

inter-regional mobility is much lower for students belonging to less educated<br />

and less wealthy households. Surprisingly enough, this is not the case. If we<br />

replicate Table 5 separately for individuals with “good” and “poor” family<br />

background at age 14 – good background being defined when the father was<br />

an entrepreneur, a manager, a high ranked director, a teacher or a high<br />

ranked white collar, and bad background when the father was in a low paying<br />

occupation – there is no difference worth noticing – see Table 6 below. The<br />

percentage of students in our dataset residing in the South who went to<br />

college in the South is 72.99 percent if <strong>from</strong> a good family background and<br />

74.12 percent if <strong>from</strong> a bad background. On the other hand, the percentage of<br />

students residing in the South before college who moved to the North for<br />

19


college is 8.22 among those with good background and 6.94 percent among<br />

those with bad background. These differences remain small even when we<br />

measure background with parental education 8 .<br />

We conclude that liquidity constraints cannot be the key reason of the<br />

observed low mobility flows of students <strong>from</strong> the South to the North. The<br />

alternative explanation is that the expected excess return <strong>from</strong> going to a<br />

Northern college is not sufficiently high to trigger mobility flows <strong>from</strong> the<br />

South. One key reason for this is that regional price differentials are known to<br />

be substantially lower in the South. If many Southern graduates work and live<br />

in the same area they went to college, the relatively low nominal earnings gap<br />

with respect to graduates <strong>from</strong> Northern colleges can be more than<br />

compensated by lower consumer prices. Another reason is that the observed<br />

college differences in wages and employment probabilities three years after<br />

graduation are simply temporary effects, which are washed away over time, as<br />

individuals settle down in the labour market and in permanent jobs.<br />

<strong>Evidence</strong> that the effects of college quality of earnings and employment<br />

probabilities wane over labour market careers is discussed by Warren, Hauser<br />

and Sheridan, 2002, and Brand and Halaby, 2003, for the US. Employers use<br />

credentials, including college quality, as a signal of skills at labour market<br />

entry, but as individuals age this signal loses importance relative to other<br />

sources of information, such as direct screening. Since mobility is triggered by<br />

expected differences in lifetime earnings profiles, university – specific<br />

temporary differences may be not sufficient to reallocate enrolment <strong>from</strong> the<br />

South to the North in the presence of cost differentials. In a way, the low<br />

mobility shown by Table 4 could simply be telling us that the internal rate of<br />

return to going to a Northern or a Southern college is not very different, once<br />

the entire profile of lifetime earnings is properly considered.<br />

Support for this alternative explanation comes <strong>from</strong> the 2002 wave of the<br />

Survey on the Income and Wealth of Italian Households (SHIW), carried out by<br />

the Bank of Italy, which includes information on the college of graduation. The<br />

sample of graduates is much smaller than the one we are using in this paper,<br />

but has the advantage of covering individuals of different age rather than only<br />

labour market entrants. We define a dummy for the young – aged <strong>from</strong> 25 to<br />

34 – and for the adult – aged <strong>from</strong> 35 to 55, and regress both monthly<br />

earnings and employment probabilities on individual controls, area of<br />

residence, field of study dummies and age dummies. We also interact both age<br />

group dummy with a dummy equal to 1 if the college of graduation was<br />

located in the North and to zero otherwise. Our key results are presented in<br />

Table 7.<br />

They show that monthly earnings do not differ in a significant way with<br />

the area where the college of graduation was located. Employment<br />

probabilities, however, differ, because the young age group <strong>from</strong> Northern<br />

colleges enjoys a significantly higher probability of employment. More<br />

importantly for our purpose, however, is the finding that this relative<br />

advantage disappears among adults.<br />

These alternative stories can explain why Southern students do not move<br />

to Northern colleges, but do they account for the differences within macro-<br />

areas, which seem to be particularly large for the students of Sicily and<br />

Calabria? The figures above show that male graduates of the university of<br />

Cosenza (CS) earn much less than other graduates, including those <strong>from</strong> other<br />

Southern universities. Female graduates of the same university also do badly,<br />

even if not as bad in relative terms as males. While this relatively poor<br />

performance can help explaining the larger mobility flows, an important<br />

additional reason is that the largest university in the region was established<br />

fairly recently, in the seventies. Before that, students <strong>from</strong> Calabria had to<br />

move elsewhere to study, and moving for college education was part of the<br />

social custom, contrary to the Sicilian experience, where universities where<br />

established in the nineteenth century.<br />

4.2 Private and public universities<br />

Why do earnings and employment probabilities three years after<br />

graduation vary depending on the college the individual graduated <strong>from</strong>? The<br />

natural answer is that colleges differ in quality, and that this quality is priced<br />

by the labour market. One important dimension of college quality is whether<br />

the university is public or private. We investigate this dimension by replacing<br />

the college dummies in the second step regression either with a dummy equal<br />

to 1 if the university is private and to zero otherwise or with the interactions of<br />

this dummy with field of study dummies. By so doing, we allow the effects of<br />

22


the private college dummy to vary with the field of study 9 . These effects can<br />

be identified because there is within-field variation in college status – either<br />

public or private.<br />

Table 8 presents the results for the net wage effects, separately for<br />

males and females. The gross effects are reported for the sake of comparison<br />

in the Appendix. Since the dependent variable is in logs, we can interpret the<br />

estimated coefficients as percentage changes. We find that going to a private<br />

university has a positive effect on graduate earnings, but that this effect is<br />

statistically significant only for female graduates. Behind the average effect<br />

there is substantial heterogeneity. Male graduates of private universities in the<br />

fields of Law and Political Science earn close to 20 percent more than<br />

graduates of public colleges in the same fields. The opposite occurs for male<br />

graduates in the fields of Medicine and Natural Sciences, who lose between 35<br />

and 6 percent with respect to their colleagues <strong>from</strong> public colleges.<br />

Turning to female graduates, going to a private university yields a 11<br />

and 8.5 percent gain in the fields of Economics; Medicine and the Humanities<br />

respectively, and a 11.4 percent loss in the field of Natural Sciences. Table 9<br />

9 Notice that there are some fields of study – Engineering for example – which are only available in public universities.<br />

We pool together some fields – Psychology, Foreign Languages and Education with Humanities, Agricultural Studies<br />

with Natural Sciences – in order to have a sufficient number of observations in the second step estimation.<br />

shows that going to a private college unambiguously increases employment<br />

probabilities, especially for female graduates.<br />

The gain for males is particularly significant in the field of Economics, and<br />

turn into a large loss in the field of Medicine. The increase in the probability for<br />

females is highest in the fields of Law and Natural Sciences, and turns again<br />

into a loss in the field of Medicine.<br />

Our results suggest that going to a private college makes a difference,<br />

especially for the probability of finding a job after graduation. Since this<br />

difference is not always positive, however, there is also heterogeneity in the<br />

performance of private universities. Such heterogeneity emerges also when we<br />

differentiate the effect of private colleges on earnings and employment not by<br />

faculty but by college location – the North and the rest of the country. As<br />

shown in Table 10, earnings gains are marginally significant for female<br />

graduates of Central and Southern private universities, and employment gains<br />

are large and significant only for the graduates of Northern private universities.<br />

Finally, Table 11 presents the results of second step regressions with<br />

private college dummies, conditional on controls for the field of study. There<br />

are 9 private universities in our sample of 68 colleges, for which we have<br />

second step estimates of wage and employment effects. We find evidence that<br />

the graduates of Castellanza, Roma LUMSA and Milano Bocconi enjoy<br />

significant earnings gains – ranging <strong>from</strong> 11 to 37 percent - with respect to the<br />

graduates of public universities. However, the male graduates <strong>from</strong> Roma<br />

Catholic and the female graduates of Brescia Catholic earn on average 15 to 35<br />

percent less than the graduates of public colleges. On the other hand, the<br />

effect on employment probability of going to a private college is positive and<br />

larger for the graduates of the private universities in Milan and neighbouring<br />

areas – Brescia and Castellanza - and negative both for the male and female<br />

graduates of Roma Catholic and for the male graduates of Roma LUMSA.<br />

4.3 College quality<br />

Is the difference made by private colleges due to observable measures of<br />

college quality? We capture quality with the (log) pupil – teacher ratio, the<br />

classical indicator used in the related literature (see Hanushek, 2002), but also<br />

control for the (log) number of students in the college and field of study and<br />

the year of establishment of the college and field of study. Since selection at<br />

entry is rare in Italian universities – and restricted to some fields of study such<br />

as Medicine – a larger size, conditional on the pupil-teacher ratio, can be<br />

interpreted as a measure of the relative attractiveness of the university and<br />

field. Similarly, if the year of establishment is a proxy of prestige, we should<br />

find that later establishment affects negatively labour market outcomes. If, on<br />

the other hand, it proxies a younger and more dynamic faculty – the<br />

correlation between year of establishment and the average age of professors in<br />

our sample is -.24, we should expect a positive relationship. We add to the<br />

regressors in Tables 8 and 9 the selected measures of college quality and<br />

present the estimates in Tables 12 and 13, limited to the case of net effects.<br />

Since both the pupil – teacher ratio and the number of students are in<br />

logs, the number in the tables can be interpreted as elasticities. We find<br />

evidence of a negative and statistically significant relationship between the<br />

pupil-teacher ratio and the college by field of study wage and employment<br />

effects. The elasticity ranges <strong>from</strong> -.128 to -.214 for earnings and <strong>from</strong> -.070<br />

to -.113 for employment probability. The faculties in private colleges of our<br />

sample have on average a pupil – teacher ratio which is close to 50 percent<br />

lower than the ratio in the faculties of public universities. Our estimates<br />

suggests that this gap translates in a 5 to 10 percent positive gap for earnings<br />

and in a 5 percent positive gap for employment.<br />

There is also evidence of a positive and statistically significant<br />

relationship between log size and the wage and employment effects, with<br />

elasticities close to .25 for earnings and to .08 for employment. In our sample,<br />

the faculties of private colleges are about 23 percent smaller than the faculties<br />

in public universities. Therefore, this effect partially cancels out the effect of<br />

the pupil – teacher ratio. One possible objection is that larger faculties may<br />

have more students who are staying longer than required to complete the<br />

degree (fuori corso). In this case, size is not necessarily an indicator of good<br />

quality. In regressions not displayed here, we control for the percentage of<br />

“fuori corso” students, but this variable is never statistically significant, nor<br />

does it change the effect of size.<br />

Finally, we find that the younger the faculty the higher the wage and<br />

employment effect. In particular, a faculty 10 years younger generates a 0.04<br />

percent increase in earnings and a 0.001 percent increase in the probability of<br />

employment. Therefore, these effects are small.<br />

The differences in pupil – teacher ratio, size and year of establishment<br />

explains an important part of the difference in wage effects between private<br />

and public institutions. The private college dummy remains, however, positive<br />

and statistically significant in the case of the employment effects, suggesting<br />

that other factors are at play.<br />

27


4.4 Family background<br />

In the previous two sections we have allowed the college by field of study<br />

effects to vary by gender. Another possibility is that they vary by family<br />

background, ad example because of the complementarities between college<br />

quality and labour market networks. We classify family background into “poor”<br />

and “good”, depending on the profession of the father when the surveyed<br />

individual was aged 14. In particular, we define family background as “good”<br />

when the father was a professional, a manager, a teacher or a high ranked<br />

white collar, and as “poor” when the father was in agriculture, a blue collar, a<br />

self-employed or a low ranking white collar.<br />

We run separate first stage regressions for good and poor background<br />

and retrieve the estimated college by field of study effects. In the second<br />

stage, we ask whether having a “good” family background can improve the<br />

labour market effects of going to a private college. Tables 14 and 15 report the<br />

results separately for wages and employment.<br />

We find that individuals with a good family background gain significantly<br />

in terms of their employment prospects if they graduate <strong>from</strong> a private<br />

university. There is little evidence that they gain in terms of entry wages,<br />

however. On the other hand, individuals with poor background who graduate<br />

<strong>from</strong> a private college do not gain significantly – in a statistical sense – in<br />

terms of higher entry wages or of a higher probability of employment. Overall,<br />

there is evidence that the returns to a private college are higher for those who<br />

come <strong>from</strong> a “better” family background, because they have a significantly<br />

better probability of employment.<br />

One reason why people enrol in private colleges and schools is because<br />

they provide access to a potentially valuable network. We find some evidence<br />

that the quality of this network and the quality of the network before going to<br />

college are complements in the production of labour market returns.<br />
