In both quantitative and qualitative field studies, the self-efficacy of entrepreneurs in the transition economies of Kazakhstan and Kyrgyzstan is examined. Using a social cognitive framework, the complex interaction among these entrepreneurs' (N=133) personal characteristics, environment, and self-efficacy is analyzed by structural equation modeling. Their self-efficacy was found to have a direct and mediating impact on performance. Another sample of entrepreneurs from these countries (N=239) qualitatively assessed what they actually do in their day-to-day activities. The findings from these two studies contribute to better understanding and have implications for successful entrepreneurial practice in countries undergoing the difficult process of transition to a market economy.
