We consider an endogenous growth model with two sectors: an intermediate input (or "upstream") sector and a final product (or "downstream") sector. Innovation takes place in both sectors. Following Gilbert and Shapiro (1990), we define patent breadth as the ability of the innovator to reap...

This paper addresses the concern of whether the determinants of patent infringement and declaratory judgment suits may affect both long-term economic performance and wage inequality. In doing so, we construct a quality-ladder R&D-based endogenous growth model, in which the institutional setting...

One critical aspect of economic development is that productivity growth and a rising standard of living are realized through more roundabout methods of production and increasing specialization of intermediate inputs and producer services. We use an extended version of the Judd-Grossman-Helpman...

I propose a Schumpeterian analysis of the growth and welfare effects of a deficit-financed cut of the tax rate on distributed dividends. I find that income per capita growth initially accelerates and then decelerates, eventually converging to a long-run value lower than the starting one....

This paper takes a new look at the long-run implications of resource abundance. Using a Schumpeterian growth model that yields an analytical solution for the transition path, it derives conditions under which the curse of natural resources occurs and is in fact a curse, meaning that welfare...

Recent empirical studies suggest a need for a ?exible patent regime responding to industry characteristics. In practice, sector-speci?c modi?cations of patent strength already exist but lack theoretical foundation. This paper intends to make up for this neglect by scrutinizing in what direction...

The influence of product market competition on growth is reconsidered by developing an extension of the basic Romerian model of horizontal product innovation. We find that the relationship between competition and growth is inverse-U shaped, provided that the non accumulated factor input (e.g....

This paper overviews the main interactions between product market competition and long run growth.We focus on the first generation of R&D-based growth models and keep distinguished the vertical from the horizontal differentiation approaches. Our main objective is to study why these two branches...

This paper studies the economic determinants of the inter-sectoral allocation of skills within an R&Dbased growth model with human capital accumulation and imperfect competition. Using an aggregateR&D technology displaying constant returns to scale in human capital, I find that steady-state...
