192 Growth Theory and <strong>Transition</strong> Economies<br />
12 110 USD (both GNP per capita at ppp). The methodological problems<br />
<strong>of</strong> plugg<strong>in</strong>g data from such varied economies <strong>in</strong>to the same<br />
regression analysis are well-known <strong>in</strong> growth theory. In the case <strong>of</strong><br />
transition<strong>in</strong>g economies this is made even more serious by the complete<br />
economic collapse <strong>of</strong> some national economies. This collapse has<br />
not been restricted to war-torn economies (for example, Bosnia and<br />
Herzegov<strong>in</strong>a, FR Yugoslavia, Georgia, Tajikistan, Azerbeijan and<br />
Armenia), but to others as well (Albania, Bulgaria for a short time).<br />
As a result, the scope for empirical results is small. Long-term trends<br />
cannot be derived and the most recent experience is not encourag<strong>in</strong>g,<br />
especially s<strong>in</strong>ce the empirical results derived under different circumstances,<br />
countries and periods do not clearly support optimism and l<strong>in</strong>earity<br />
but, on the contrary, quite substantially question it.<br />
11.4 Optimism, l<strong>in</strong>earity and growth theory<br />
Because <strong>of</strong> the problems described above, the empirical study <strong>of</strong> growth<br />
<strong>in</strong> transition<strong>in</strong>g economies cannot have great ‘mileage’. As a result, the<br />
importance <strong>of</strong> and reliance on growth theory necessarily <strong>in</strong>creases.<br />
The optimistic and l<strong>in</strong>ear approach to transition f<strong>in</strong>ds its strongest support<br />
<strong>in</strong> basic ma<strong>in</strong>stream growth theory. The Neoclassical Solow-Swann<br />
model (with or without Ramsey optimiz<strong>in</strong>g households) is quite clear on<br />
both issues. The Solow-Swann model’s ‘world’ generates only one equilibrium<br />
steady state growth path. This equilibrium steady state growth path<br />
is generated by the assumptions <strong>of</strong> well-behaved production functions<br />
and preferences, perfect competition, pr<strong>of</strong>it maximiz<strong>in</strong>g firms and welfare<br />
maximiz<strong>in</strong>g households. Furthermore, this path is globally stable so<br />
that, regardless <strong>of</strong> the economy’s <strong>in</strong>itial conditions, the economy converges<br />
over time to this one growth path which is common to all<br />
economies. L<strong>in</strong>earity is thus dealt with by the existence <strong>of</strong> a s<strong>in</strong>gle steady<br />
state growth path, and optimism by the unavoidable convergence <strong>of</strong><br />
economies to this path. The Neoclassical Solow-Swann model allows per<br />
capita GDP and per capita consumption to grow. Additional assumptions<br />
are required to enable per capita GDP and consumption to rise, while<br />
ma<strong>in</strong>ta<strong>in</strong><strong>in</strong>g equilibrium steady state and stability. In particular, Harrod<br />
neutral labour augment<strong>in</strong>g technical progress is <strong>in</strong>cluded, and this has<br />
the properties <strong>of</strong> undiscrim<strong>in</strong>at<strong>in</strong>g manna from heaven.<br />
The model’s equilibrium steady state growth rate is determ<strong>in</strong>ed<br />
by the exogenously given rate <strong>of</strong> growth <strong>of</strong> the population and exogenously<br />
given rate <strong>of</strong> growth <strong>of</strong> technical progress. While the exogenous<br />
fundamentals <strong>of</strong> the model rema<strong>in</strong> unchanged, different values <strong>of</strong>
