High levels of net migration to the UK have contributed to growing cultural diversity, and researchers are turning their attention to the long-term effects of diversity on productivity. Yet little is known about these issues. This paper asks: what are the links between the composition of firms'...

We empirically analyze whether support by the parent organization in the early (nascent and seed) stage speeds up the process of commercialization and helps spin-offs from public research organizations generate first revenues sooner. To identify the impact of support by the parent organization,...

We examine immigrant entrepreneurship and the survival and growth of immigrant-founded businesses over time relative to native-founded companies. Our work quantifies immigrant contributions to new firm creation in a wide variety of fields and using multiple definitions. While significant...

Immigrants account for about a quarter of US invention and entrepreneurship despite a policy environment that is not well suited for these purposes. This chapter reviews the U.S. immigration policy environment that governs how skilled migrants move to America for employment-based purposes. We...

We analyze the implications of entrepreneurial spawning for a variety of firm characteristics such as size, focus, profitability, and innovativeness. We examine the dynamics of spawning over time. Our model accounts for much of the empirical evidence relating to the relation between spawning and...

A randomized controlled trial with 945 entrepreneurs in Jamaica shows positive short-term impacts of soft-skills training on business outcomes. The effects are concentrated among men and disappear 12 months after the training. The main channel is increased adoption of recommended business...

A randomized control trial with 945 entrepreneurs in Jamaica shows positive shortterm impacts of soft-skills training on business outcomes. The effects are concentrated among men, and disappear twelve months after the training. We argue that the main channel is increased adoption of recommended...

Start-ups of new firms are important for economic growth. However, start-up rates differ significantly between countries and within regions of the same country. A large empirical literature studies the reasons for this and attempts to identify the regional determinants of start-ups. In contrast,...

We explore how financial constraints distort the entry decisions among otherwise productive entrepreneurs and limit growth of promising young firms. A model of liquidity-constrained entrepreneurs suggests that the easing of credit constraints can induce more entry of firms with greater long-run...
