170 Privatization: Evidence from Estonia<br />

effects <strong>of</strong> privatization upon enterprise performance, most studies <strong>of</strong><br />

transition economies omit what are potentially important variables.<br />

For example, many empirical studies fail to exam<strong>in</strong>e the potential<br />

effects <strong>of</strong> what <strong>Horvat</strong> (1982: ch. 6) calls ‘real participation’ upon economic<br />

performance. In addition, most studies do not allow for changes<br />

<strong>in</strong> dom<strong>in</strong>ant/majority ownership, nor do they take <strong>in</strong>to account the<br />

potential effects on performance <strong>of</strong> ownership by other (m<strong>in</strong>ority)<br />

groups. 13 Hence <strong>in</strong> our empirical work, we not only report f<strong>in</strong>d<strong>in</strong>gs<br />

from estimates which emulate some <strong>of</strong> the key strategies adopted by<br />

Frydman et al. (1997) but also estimate specifications which <strong>in</strong>volve<br />

substantial extensions <strong>of</strong> that approach. 14 In addition, we always<br />

<strong>in</strong>clude dummy variables for <strong>in</strong>dustries and regions. Thus, they help to<br />

isolate the privatization effect and hopefully produce more reliable<br />

estimates <strong>of</strong> the privatization effect. However, one consequence <strong>of</strong> this<br />

extension is that the transition effect is no longer a unique number,<br />

but now differs by <strong>in</strong>dustry or region. Hence, when discuss<strong>in</strong>g our<br />

f<strong>in</strong>d<strong>in</strong>gs, we will not consider the transition effect <strong>in</strong> great detail.<br />

In one set <strong>of</strong> specifications we use estimate equations <strong>of</strong> the form:<br />

AVPERF o INIPERF PRV i i IND Tall<strong>in</strong>n (1)<br />

where AVPERF is average performance computed for some measure <strong>of</strong><br />

performance us<strong>in</strong>g annual data over the period 1994–7, except for<br />

those firms which were privatized dur<strong>in</strong>g that period <strong>in</strong> which case it is<br />

measured relative to the year <strong>of</strong> privatization, INIPERF is a correspond<strong>in</strong>g<br />

measure <strong>of</strong> the level <strong>of</strong> performance dur<strong>in</strong>g the first year <strong>of</strong> privatization,<br />

and PRV is a privatization dummy. 15 For ease <strong>of</strong> comparability<br />

with Frydman et al. (1997), performance measurers are rates <strong>of</strong> growth<br />

and many <strong>of</strong> the measures <strong>of</strong> performance are the same set as those<br />

used <strong>in</strong> that study, for example, the growth <strong>in</strong> employment and the<br />

growth <strong>in</strong> labour productivity. In addition, our data enable us to construct<br />

the ratio <strong>of</strong> exports/sales, though other measures, notably costs,<br />

are not available for all years. We always <strong>in</strong>clude IND, which is a set <strong>of</strong><br />

<strong>in</strong>dustry dummies, as well as a dummy variable for whether or not the<br />

firms are located <strong>in</strong> the capital district (Tall<strong>in</strong>n). In a related set <strong>of</strong> estimates,<br />

we replace the privatization dummy (PRV) by a set <strong>of</strong> dummy<br />

variable measures for ownership. This set <strong>of</strong> private ownership variables<br />

(hereafter the OL vector) conta<strong>in</strong>s measures <strong>of</strong> majority ownership<br />

(unlike most studies which use measures <strong>of</strong> dom<strong>in</strong>ant ownership).<br />

Also, as is the practice <strong>in</strong> the literature, the type <strong>of</strong> private ownership<br />

(which <strong>of</strong>ten changes dur<strong>in</strong>g the period) is assessed <strong>in</strong> 1997 – that is at<br />

the end <strong>of</strong> the period <strong>of</strong> study.
