This paper re-examines the empirical relationship between stock market
s and economic growth. In contrast with Atje and Jovanovic (Stock Mark
ets and Development, European Economic Review 37, pp. 632-640, 1993) i
t finds no hard evidence that the level of stock market activity helps
to explain growth in per capita output. Estimating their model using
current investment rather than lagged investment suggests that the sto
ck market effect may be weaker than they found. Two stage least square
s is used to circumvent the possible endogeneity of current investment
. The sample is divided into developed and less developed countries. F
or the less developed sample, the stock market effect, as with the ful
l sample, is at best very weak. For the developed countries, however,
stock market activity does have some explanatory power.
