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...

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 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...

Portugal’s export performance over the past decade has been impressive, helping to reduce external imbalances. This partly owed to a sequence of structural reforms that benefited the productivity of the export sector and led to an increase in its size. Nonetheless, exports as a share of GDP...

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...

We analyze the impact of obsolescence of economic inventions by incorporating maintenance costs in the endogenous growth model of expanding product varieties. This contrasts with the existing literature, which ignores maintenance costs and uses the model of quality improvements to describe...

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...

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...

China is well-placed to avoid the so-called “middle-income trap” and to continue to converge towards the more advanced economies, even though growth is likely to slow from near double-digit rates in the first decade of this millennium to around 7% at the 2020 horizon. However, in order to...
