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...

This article shows - on both conceptual and empirical grounds - the importance of business cycles in affecting key relationships between innovation and international performance. While periods of upswing are characterised by a well documented 'virtuous circle'. between innovation inputs, new...

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 construct and estimate a unified model combining three of the main sources of cross-country income disparities: differences in factor endowments, barriers to technology adoption and the inappropriateness of frontier technologies to local conditions. The key components are different types of...

Recent evidence on world trade patterns reveals North-South specialization across products of the same industries and product groups but different quality, which is not matched by the predictions of traditional and new trade theory. This paper analyzes a model of North-South trade and endogenous...

Utilising panel data for 14 East European transition economies, we find support for the hypothesis that a greater degree of export variety relative to the U.S. helps to explain relative per capita GDP levels.The empirical work relies upon some direct measures of product variety calculated from...
