The paper examines economic, political, and institutional determinants of the propensity of privatization as well as the sensitivity of privatization under the Association of Southeast Asian Nations (ASEAN) context over the observational period from 1988 to 2008, with the Asian Financial Crisis being the median point of the observational period. This is particularly to investigate the organic progression of privatization of ASEAN nations as an isolated endogenous phenomenon. This paper, via a two-stage quantitative technique, aims to exhibit novel, and to a degree inventive insights that are unique to the context of ASEAN, as well as to identify potential policy implications directing towards how ASEAN policymakers may steer their national development policies to manufacture constructive economic, political, and institutional conditions needed to foster privatization processes. Our findings indicate that GDP per capita, current account balance, and stock market capitalization are statistically the key moving parts that contribute to the propensity of privatization as well as the sensitivity of privatization under the ASEAN context.
