THEORIES OF GROWTH AND DEVELOPMENT
Qui si convien
lasciane ogni sospetto
Ogni vilta convien che qui sia morta*
* "Here all mistrust must be left behind
/ Here all cowardices must be dead" K. Marx quoting Dante in his
introduction to the Contribution
to the Critique of Political Economy.
"... I do not see how one can look at figures like
these without seeing them representing possibilities.
Is there some action a government of India could take that would lead the
Indian economy to grow like Indonesia's or Egypt's? If so, what
exactly? If not, what is it about the "nature of India"
that makes it so? The consequences for human welfare involved in questions like
these are simply staggering: once one starts to think about them, it is hard to
think about anything else". (Lucas, 1988: 5).

Transitional dynamics of theTurkish Economy towards Steady State
Suppose that the national output is given by a Cobb-Douglas
function with labor augmenting technological change. Barro and Sala-i-Martin (1995) suggest that the gap between national
output at any date and the steady state of a given economy is closed at the
constant rate: b = (1-a)(x + n + d ) where a is share
of capital in national output; x is rate of technological productivity change;
n is population growth rate; and d is rate of depreciation.
Data from Turkish economy suggest the following
values for the selected variables: x = 0.015 (Uygur, 1991); n = 0.017 (SIS) ; a = 0.55 (Mercenier and
Yeldan, 1997); and d = 0.10. Given these estimates, we calculate b = (1-0.55)(0.015 + 0.017 + 0.10) or b = 0.06. In other words 6%
of the gap between the current level of national output and its steady state is
eliminated per annum.
We can further calculate the half life of this
distance as t (half life) = In0.5/-b = 11.7 years.
So half of this distance is to
be covered in aproximately 11.7 years. If we continue on this manner, we find that %75 of the
gap to the steady state of the Turkish economy is to vanish in 24 years; 87.5%
in 48 years; and 94% will vanish in 96 years.
Time to go lads....
