A Method for Measuring International Openness

摘要

The Author illustrates a method for measuring international openness by bringing forward some examples. The index proposed measures the capacity of countries for a given phenomenon, adjusted for their weight in the phenomena concerned. In this study, the Index is applied to measure the degree of openness to international migration in a number of world countries. Beyond migration, the Index can be applied to other transferable phenomena, such as trade, foreign direct investment, and so on.
