framework that contains multiple innovation sizes, multiproduct firms, and entry/exit. Firms invest in exploration R&D to … regularities regarding innovation and growth differences across the firm size distribution. We also incorporate patent citations …

We model spatial clusters of similar firms. Our model highlights how agglomerative forces lead to localized, individual connections among firms, while interaction costs generate a defined distance over which attraction forces operate. Overlapping firm interactions yield agglomeration clusters...

Measures of entrepreneurship, such as average establishment size and the prevalence of start-ups, correlate strongly with employment growth across and within metropolitan areas, but the endogeneity of these measures bedevils interpretation. Chinitz (1961) hypothesized that coal mines near...

We show that, in a model without commitment to future policies, geoengineering breakthroughs can have adverse environmental and welfare effects because they change the (equilibrium) carbon taxes. In our model, energy producers emit carbon, which creates a negative environmental externality, and...

We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A …

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 studies a simple model of experimentation and innovation. Our analysis suggests that patents may improve the … project to implement. A successful innovation can be copied by other firms. Symmetric equilibria (where actions do not depend … equilibria). In contrast to patents, subsidies to experimentation, research, or innovation cannot typically achieve this …
