This paper develops an empirical model to separate the unobserved fact
ors of 'opportunity' and 'willingness' in the decision of labor force
participants to become self-employed or not. The estimation results su
ggest that the majority of young Americans is willing to switch to sel
f-employment but that opportunity is a major constraint, especially th
rough finance. Entrepreneurial ability aspects that can compensate for
a lack of capital are scarce.
