Abstract
This paper uses a simple model of mean-variance capital markets equilibrium with proportional
transactions costs to analyze the competition of stock markets for investors. We assume that equity
trading is costly and endogenize transactions costs as variables strategically influenced by stock
exchanges. Among other things, the model predicts that increasing financial market correlation leads
to a decrease of transaction costs, an increase in cross-border trading activity, and to a decrease in the
home bias of international equity flows. These predictions are consistent with the recent evolution of
international stock markets.
