We model the role of fear of failure in entry and investment decisions of entrepreneurs using the framework of loss aversion.
When an individual's threshold for success is sufficiently high, fear of failure motivates additional investment.
When the threshold for success is low or equal to the foregone outside option, fear of failure is always de-motivating.
Regardless of the success threshold, fear of failure is negatively associated with entry into entrepreneurship.
We highlight the importance of the interaction between the degree of fear of failure and the aspirations of the entrepreneur.
