On the optimality of international capital market integration
Abstract
The focus of this paper is on the benefits to investors, arising out of the integration of the capital markets of different countries. The notion that an expansion in the opportunity set of individual investors causes improvements in their welfare is analyzed to take account of the effects on their wealth. With the supplies of investments held constant, the effects of changes in the macroparameters of the risk-return pricing relationship, caused by the merger of capital markets, on the wealth of individuals in the new equilibrium, are determined. Using three specific utility functions – quadratic, exponential and logarithmic – it is shown that international capital market integration is Pareto-optimal, i.e., the welfare of individuals in the economies considered never declines, and will generally improve. The effect of expansion of the opportunity set, due to the integration of capital markets, nullifies the effect of a possible negative change in wealth.
