Pressure on public finances has increased scrutiny of public support for innovation. We examine two particular issues. First, there have been many recent calls for the (relatively new) UK R&D subsidy to be extended to other “research” activities, such as software. Second, argument still...

This paper looks at the channels through which intangible assets affect productivity. The econometric analysis exploits a new dataset on intangible investment (INTAN-Invest) in conjunction with EUKLEMS productivity estimates for 10 EU member states from 1998 to 2007. We find that (a) the...

"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...

We (a) propose an implementable innovation index, (b) relate it to existing innovation definitions and (c) show whole-economy and industry-specific results for the UK market sector, 2000-2005. Our innovation measure starts by observing that we could get more GDP without innovation by simply...

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...

How and why does the firm size distribution differ across countries? Using two datasets covering more than 30 countries, this paper documents that several features of the firm size distribution are strongly associated with income per capita: the entrepreneurship rate and the fraction of small...

Developing and emerging economies have high entrepreneurship rates and relatively many small firms. There is enormous heterogeneity among these firms and entrepreneurs. This paper presents a simple occupational choice model that captures motives for entrepreneurship at both edges of the size...

Poor countries have low rates of wage employment and high rates of self-employment. This paper shows that they also have high rates of unemployment relative to wage employment, and that self-employment is particularly high where the unemployment-wage employment ratio is high. I interpret high...

Output per worker is lower in poor countries than in rich countries, and relatively more so in the agricultural sector. Sorting of heterogeneous workers can contribute to explain this fact if comparative and absolute advantage are aligned in agriculture, implying that average productivity in...

Poor countries have low wage employment and high self-employment. This paper shows that they also have high unemployment relative to wage employment, and that self-employment increases with this ratio. To understand the sources of these patterns, I build a search and matching model with choice...
