These figures for the four Asia Pacific economies indicate that there is a wide variation in
efficiency among the countries. While Indonesia and Malaysia appear to have similar levels
of average efficiency scores, both Singapore and Thailand have higher scores. The developed
countries and the OECD group included in another study indicate an average score which is
higher than those for Indonesia. One question addressed is to examine if the mean scores
have changed in recent years, given the reforms and also world-wide instabilities affecting
this open economy.
