The role of patents is threefold: first, they are important to state the property rights of an invention; second, they are necessary to secure financing for starting a new venture; third, they are fundamental to recoup R&D investments. The main difficulty in preventing unauthorized use of an...

This paper addresses the empirical relationship between the level of competition and the rate of productivity growth across thirty sectors of the French production system during the period 1978- 2015. It shows that there exists an optimal level of competition for each sector that is defined by...

This paper studies a generalization of the Schumpeterian models with endogenous market structure that allows the overall production structure to be more than linear in the growth driving factor and yet generates endogenous growth, defined as steady-state, constant, exponential growth of income...

This paper integrates fertility choice and exhaustible resource dynamics in a tractable model of endogenous technological change. The analysis shows that, under the right conditions, the interdependence of population, resources and technology produces a transition from unsustainable...

We analyze the relative growth performance of open economies in a two-country model where different endowments of labor and a natural resource generate asymmetric trade. A resource-rich economy trades resource-based intermediates for final manufacturing goods produced by a resource-poor economy....

This paper studies the impact of income inequality on the level of innovative activities in a model where innovations result in quality improvements. The market for quality goods is characterized by a natural oligopoly with three types of consumers - rich, middle class and poor. In general, we...

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...

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 studies have documented several trends in the U.S. market structure since the 1980s, such as the rise of large firms' markups and their profit margins. An important but not emphasized trend is the rise of the fixed operating costs of large firms. This trend is so salient that the...

This paper extends the Schumpeterian model of creative destruction by allowing followers' cost of innovation to increase in their technological distance from the leader. This assumption is motivated by the observation the more technologically advanced the leader is, the harder it is for a...
