Ascending auctions offer agents the option to wait and see before deciding to drop out. We show that in contexts where as time proceeds agents get finer and finer estimates of their valuations, incentives to drop out at one's expected valuation are weak: it is optimal for agents to wait and see....

Government-sponsored auctions for production rights (e.g., license auctions, privatizations, etc.) shape the industry structure. Are there mechanisms that induce an efficient industry structure (at least when there are no positive costs to public funds)? The answer is "no" whenever firms have...

There is a long normative 'Social Contract' tradition that attempts to characterize ex-post income inequalities that are agreeable to all 'behind a veil of ignorance.' This paper takes a similar normative approach to characterize social decision-making procedures. It is shown that quite...

In this lecture, we use Schumpeterian growth theory, where growth comes from quality-improving innovations, to elaborate a theory of growth policy and to explain the growth gap between Europe and the US. Our theoretical apparatus systematizes the case-by-case approach to growth policy design....

How does entry affect productivity growth of incumbents? In this paper we exploit policy reforms in the United Kingdom that changed entry conditions by opening up the U.K. economy during the 1980s and panel data on British establishments to shed light on this question. We show that more entry,...

We construct a model where the equilibrium organization of firms changes as an economy approaches the world technology frontier. In vertically integrated firms, owners (managers) have to spend time both on production and innovation activities, and this creates managerial overload, and...

We use data on publicly traded U.K. firms to investigate whether financing choices differ systematically with R&D intensity. As well as looking at a balance sheet measure of the debt/assets ratio, we also consider the probability of raising finance by issuing new equity, and the shares of bank...

We analyze an economy where firms undertake both innovation and adoption of technologies from the world technology frontier. The selection of high-skill managers and firms is more important for innovation than for adoption. As the economy approaches the frontier, selection becomes more...
