Innovation is key to technology adoption and creation, and to explaining the vast differences in productivity across and within countries. Despite the central role of the entrepreneur in the innovation process, data limitations have restricted standard analysis of the determinants of innovation...

We extend Lazear's theory of skills variety and entrepreneurship in three directions. First, we provide a theoretical framework linking new business creation with an entrepreneur's skill variety. Second, in this model we allow for both generalists and specialists to possess skill variety. Third,...

In recent years, the economics of migration literature has shown a substantial growth in papers exploring host country impacts beyond the labour market. Specifically, researchers have begun to shift their attention from labour market and fiscal changes, towards exploring what we might call...

According to Gibrat’s Law of Proportionate Effect, the growth rate of a given firm is independent of its size at the beginning of the period examined. While earlier studies tended to confirm the Law, more recent research generally rejects it. This paper reconciles these two streams of...

"Entrepreneurs out of necessity" identified by the Global Entrepreneurship Monitor survey are a sizeable group across countries. They tend to have low education, run smaller firms, expect their firms to grow less, but are likely to stay in the market. This evidence is a challenge for existing...

In contrast to the very large literature on skill-biased technical change among workers, there is hardly any work on the importance of skills for the entrepreneurs who employ those workers, and in particular on their evolution over time. This paper proposes a simple theory of skill-biased change...
