Abstract: The aim of this paper is to develop an integrated multiple criteria decision making approach combining the analytic hierarchy process (AHP) and the goal programming (GP) model to study the impact of a mixture of investment barriers on international portfolio selection, and therefore the home bias puzzle from the viewpoint of G-7 investors over the period 2001-2009. The AHP is used to determine the suitable international equity portfolios with respect to seven barriers to international investment. The GP model, incorporating the market weights of the maximum return, minimal variance, and AHP portfolios is formulated to determine the optimal international equity portfolios. The main results show that the AHP-GP optimal international portfolio weights are different from those predicted by the I-CAPM. Also, except for French and US investors, home bias values determined according to the AHP-GP portfolios are lower than those calculated on the basis of the value-weighted world market portfolio.
