This paper investigates the causal relationship between stock market development and economic growth for Germany for the period 1965-2007 using a Vector Error Correction Model (VECM). The purpose of this paper was to examine the long-run relationship between these variables, applying the Johansen co-integration analysis based on the classical unit roots tests. The results of Granger causality tests indicated that there is a unidirectional causality between stock market development and economic growth with direction from stock market development to economic growth.

More recently, the emphasis has increasingly shifted to stock market indexes and the effect of stock markets on economic development.

Another important aspect through which stock market development may influence economic growth is risk diversification. Obstfeld  suggests that international risk sharing through internationally integrated stock markets improves the allocation of resources and accelerates the process of economic growth. Evolution of stock market has impact on the operation of banking institutions and hence, on economic promotion....
