| Outline of Final Research Achievements |
In this research, we have explored the optimal asset allocation that minimizes portfolio shortfall risk from the target of inflation rate or wage hike rate, using VAR model in order to take into account of time series correlation of asset return.
As a result, firstly, we confirm the structural change in the economy and market in early 1990s from change in VAR coefficient matrix. Secondly, in portfolios that minimize second-order lower partial moment, the sum of domestic and overseas equity allocation surpasses 10% only when A. expected return of equity is relatively high as experienced prior to 1990s, B. the level of add-on return on inflation or wage hike included target return is substantial, and C. investment horizon is longer than 3 to 5 years. Thirdly, the experience in foreign country public pension shows liquidity cost and risk pose a serious concern for a large scale pension fund to make an investment in alternative asset classes and improve portfolio efficiency.
