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...

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 present a Hotelling model of price and advertising competition between prescription drugs that differ in quality/side e¤ects. Advertising results in the endogenous formation of two consumer groups: brand loyal and non-brand loyal ones. We show that advertising strategies are strategic...

We analyse the behaviour of a monopolistic firm in general equilibrium when the firm’s decision are taken through shareholder voting. We show that, depending on the underlying distribution, rational voting may imply overproduction as well as underproduction, relative to the efficient level....

This paper aims at testing the maintained assumption that firms' objective is to maximize the expected net present value (ENPV) of profits. The idea is to examine pricing behaviour of a monopolist facing a dynamic demand where current sales influence future demand. Empirically, I estimate an...

We look at the corporate performance of family firms listed on the French stock exchange between 1994 and 2000. On the French stock market, approximately one third of the firms are widely held, another third are founder controlled and the remaining third are heir-controlled family firms. We find...

We develop a model of internal governance where the self-serving actions of top management are limited by the potential reaction of subordinates. We find that internal governance can mitigate agency problems and ensure firms have substantial value, even without any external governance. Internal...

This paper interprets the existing evidence on enterprise restructuring in Poland, Hungary and the Czech Republic. Despite differences in restructuring policies, the pattern of observed restructuring appears similar in the three countries. Contrary to initial expectations, managers of SOEs have...

I characterize the effects of empirically observed managerial incentives on long-run oligopolistic competition. When managers have a preference for smooth time-paths of profits – as revealed by the empirical literature on ‘income smoothing’ – manager-led firms can sustain collusive...
