Key words: entrepeneurs, decision making

This dissertation is concerned with how entrepreneurs make decisions when they have limited resources and are faced with uncertainty. The dissertation looks at how the decisions made influence the fast internationalization of the entrepreneurial firms, the process of developing new-to-the-world innovations, and how investment decisions are made.  The results show that entrepreneurs in the SIDS context are flexible and use a combination of different decision styles. Furthermore, when making investment decisions, entrepreneurs continuously evaluate how much money they have to invest versus how much money they are willing to lose in the worst case scenario.
