What form of intellectual property rights (IPR) policy contributes to economic growth? Should technological followers be able to license the products of technological leaders? Should a company with a large technological lead receive the same IPR protection as a company with a more limited lead?...

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

We present a new approach to endogenizing technological spillovers. Firms choose continuous levels of a cost-reducing innovation before they engage in competition for each other's R&D-employees. Successful bids for the competitor's employee then result in higher levels of cost-reduction....

We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A key feature is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using detailed US...

We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A new and central economic force is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model...

We augment a Schumpeterian growth model with a public basic-research sector to examine how much a country should invest in basic research. We find that the closer the country is to the world’s technological frontier the more the government should invest in basic research. Basic-research...

In this paper we study the incentives for basic-research investments by governments in a globalized world. For this purpose, we develop a two-country Schumpeterian growth model in which each country chooses its basic-research investments. We find that a country's basic-research investments...
