We study the interactions between technological change, resource scarcity and population dynamics in a Schumpeterian model with endogenous fertility. There exists a pseudo- Malthusian equilibrium in which population is constant and income grows exponentially: the equilibrium population level is...

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 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...

This paper explores the theoretical channels by which financial crises might have an impact on long-run growth. By exploiting occasionally binding financial constraints, we produce a model that generates endogenous crisis episodes featuring permanent falls in productivity, without generating...

This paper analyzes the normative side of a Ramp;D growth model in which market structure and growth are jointly determined in the equilibrium of a one-sector economy under monopolistic competition. We find that a distortion in the allocation of Ramp;D, namely the presence of technological...

This paper analyzes how changing the expected length of intellectual property (IP) protection affects economic growth and the welfare of rich and poor consumers. The analysis is based on a product-variety model with non-homothetic preferences and endogenous markups in which, in accordance with...

The Information Technology (IT), the Internet, or the Computing & Communications (C&C) technology revolution has been central to the economic discussion for several decades. Before the mid-1990s the catchword was the “productivity paradox” coined by Robert Solow, who stated in 1987 that...

I study the joint determination of market structure and growth in an oligopolistic economy. Firms run in-house R&D programs to produce over time a continuous flow of cost-reducing (incremental) innovations. In symmetric equilibrium, the dispersion of resources across firms prevents the...

We utilize Schmookler's (1966) concept of demand-induced invention to study the role of income inequality in an endogenous growth model. As rich consumers can satisfy more wants than poor consumers, both prices and market sizes for new products, as well as their evolution over time, are...

Evidence shows that firms build their market position by consistently investing in R&D over time and accumulating knowledge protected by secrecy, patents and other appropriability devices. To explore the macroeconomic implications of this fact, I construct an economy where oligopolistic firms...
