In this Paper we estimate the dynamic relationship between resources used in R&D by some OECD countries and their innovation output as measured by patent applications. We first estimate a long-run cointegration relation using recently developed tests and panel estimation techniques. We find that...

We analyze the impact of obsolescence of economic inventions by incorporating maintenance costsin the endogenous growth model of expanding product varieties. This contrasts with the existingliterature, which ignores maintenance costs and uses the model of quality improvements todescribe...

We present a class of dynamic general-equilibrium models of education, innovation and technology transfer to explain the evolution of industries and aggregate growth in closed and open economies. Firms employ educated workers in order to develop higher-quality products. The realization of...

We explore the potential roles of industrial policy in the transition from middle-income to high-income status, and the actual experience of industrial policy in emerging economies. Guided by the conceptual framework of the neo-Schumpeterian approach, we look at industrial policy in the context...

This paper presents a two-countries dynamic model of Schumpeterian growth with two innovative R&D sectors in each country: a vertical R&D sector that improves the quality of existing differentiated products and a horizontal R&D sector that creates new differentiated products. The two countries...

This article studies the implications of highly skilled labor international migration in a two-country dynamic stochastic general equilibrium model. The model considers three types of workers: Science, Technology, Engineering, or Mathematics (STEM) workers, non-STEM college educated workers, and...

We analyze recent contributions to growth theory based on the model of expanding variety of Romer (1990). In the first part, we present different versions of the benchmark linear model with imperfect competition. These include the “labequipment” model, labor-for-intermediates” and...

This article considers innovation, intellectual assets and intellectual property rights (IPRs) since 1990, with particular regard to the high-income countries. It begins with a discussion of the changing nature of innovation and the increasing importance of intellectual assets, then continues...
