Abstract
Food security is one of the most important issues in the world. Although Food and Agriculture Organization of the United Nations (FAO) acknowledges its definition, the FAO, different countries, and research institutes all develop various kinds of food security indices to reflect the level of food security among target countries.
Based on the current income level, distribution and calorie consumption per capita in the net-import countries of Taiwan, Japan, and Korea, there are no food availability or access problems under traditional food security indices as defined by the FAO. However, the stability of food supply is a threat in these countries. The traditional food security indices do not fully reflect these countries’ ability to ensure domestic food security or their level of food security.
The research of this thesis uses the concept of portfolio theory to measure the portfolio risk of rice, maize, soybeans and wheat arising from domestic production, import, and stockpiling sources within Taiwan and Japan. Empirical results show that when international food prices fluctuate, the FSRI of these staple crops will be affected greatly, which could more adequately reflect the level of food security in Taiwan and Japan for the past 20 years.
