Assessing the Effect of Investment Barriers on International Capital Flows Using an Expert‐Driven System

The analytic hierarchy process (AHP) is an expert‐driven system that has been applied to numerous fields but has yet to be applied to portfolio selection. This study shows how the AHP can be modeled to effectively assess barriers to cross‐border investments. It demonstrates that it is capable of effectively contributing to the selection of an optimal investment portfolio (OIP), herein a diversified portfolio composed of national markets where barriers to capital flows are least likely to adversely affect its return.
