We develop a general equilibrium model in which heterogeneous entrepreneurs produce output in the presence of financing constraints. We model granular uncertainty as the shocks that affect the uncertainty in future idiosyncratic productivity without changing the cross-sectional dispersion of...

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...

This paper analyzes a model of oligopolistic competition with ongoing investment. It incorporates the following models as special cases: incremental investment, patent races, learning-by-doing, and network externalities. We investigate circumstances under which a firm with low costs or high...

Many manufacturing industries, including the computer industry, have seen large increases in productivity growth rates and have experienced a reduction in average establishment size and a decrease in the variance of the sizes of plants. A vintage capital model is introduced where learning...

In theory, uncertainty and sunk costs can influence industry dynamics through the option value and financing constraints channels. Empirical evaluation of these models in the context of industry dynamics are, however, at a nascent stage. Our empirical analysis, covering 267 U.S. manufacturing...

Patent scope is central to the sale of ideas, which can spur economic growth and provide significant gains from trade. Awarding an inventor a patent on a new idea partially solves a commitment problem that would otherwise prevent the inventor from selling the idea. (Arrow, 1962). In the absence...

We extend the basic Schumpeterian endogenous growth model by allowing incumbents to undertake innovations to improve their products, while entrants engage in more “radical” innovations to replace incumbents. Our model provides a tractable framework for the analysis of growth driven by both...

This paper examines the transmission of productivity differences among banks and of industry productivity growth over time to lower (higher) interest rates of loans (deposits) and higher customer accessibility to bank services. For this purpose, it models spatial competition in retail banking...

Starting in 2013, authors of copyrighted work and their successors will be able to terminate every assignment and license 35 years after execution. These termination rights are inalienable and are expected to have a substantial impact on some industries, and in particular, the music...
