We collect information on prenatal testosterone in a large sample of entrepreneurs by measuring the length of their 2th to 4th fingers in face to face interviews. Entrepreneurs with higher exposure to prenatal testosterone (lower second to fourth digit ratio) manage larger firms, are matched...

The ratio of second to fourth digit (2D4D) has been shown to correlate negatively with entrepreneurial skills and financial success. We document that in a sample of entrepreneurs women have a lower 2D4D ratio than men, in sharp contrast with the features of the distribution in random samples....

We analyze the relationship between firm-level innovation activities and firms’ propensity to start exporting for firms in a small open economy. We measure innovation by innovative effort (R&D) as well as by innovative output (product and process innovation). After carefully correcting for...

In the large literature on firm performance, economists have given little attention to entrepreneurs. We use deaths of more than 500 entrepreneurs as a source of exogenous variation, and ask whether this variation can explain shifts in firm performance. Using longitudinal data, we find large and...

This Paper studies the impact of wage growth on the evolution of employment in an intertemporal general-equilibrium model with endogenous productivity growth. For real wage growth above laissez-faire levels, we obtain steady-state equilibria in which productivity grows at the same rate as wages,...

This paper examines the importance of buyer-supplier relationships, geography and the structure of the production network in firm performance. We develop a simple model where firms can outsource tasks and search for suppliers in different locations. Low search and outsourcing costs lead firms to...

We consider an economy where property rights are necessary to ensure sufficient rewards to ex-ante investments. Because enforcement of property rights influences the ex-post distribution of rents, there is room for corruption. We characterize the optimal organization of society and the optimal...

This paper addresses the relationship between patent protection and investment in the development of new pharmaceutical treatments. The TRIPS Agreement, which specifies minimum levels of intellectual property protection for countries in the World Trade Organization, has increased levels of...

This paper uses a rich panel dataset of Spanish manufacturing firms (1990-2006) and a propensity score reweighting estimator to show that multinational firms acquire the most productive domestic firms, which, on acquisition, conduct more product and process innovation (simultaneously adopting...

We analyse a micro-panel data set to investigate the effect of regional institutional environment and economic factors on Russian new firm entry rates across time, industries and regions. The paper builds on novel databases and exploits inter-regional variation in a large number of institutional...
