In a decentralized open economy model with an endogenous growth sector and a renewable resource sector a steady state–balanced growth equilibrium will at best be attained by chance. An interior equilibrium where both sectors exist and the resource sector is in equilibrium while the other...

Why did England industrialize first? And why was Europe ahead of the rest of the world? Unified growth theory in the tradition of Galor-Weil (2000) and Galor-Moav (2002) captures the key features of the transition from stagnation to growth over time. Yet we know remarkably little about why...

Empirical evidence has recently pointed to the lack of any relationship between R&D intensity (variously defined and measured) and economic growth in the post-war period in the United States and other OECD countries. Using a framework that integrates human capital accumulation and purposive...

This paper addresses the dynamics of income inequality, both within and across countries. In an endogenous growth model with North-South trade, the dynamics of income inequality depend on the ability of workers to adapt to new technologies, captured by the quality of education. For developing...

Even though most countries have agreed to a harmonization of intellectual property rights by signing the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), there is still much dispute about the optimal level of protection of intellectual property rights in the world....

Over the past decades, private R&D spending in the US and other developed countries has been growing faster than GDP. In the United States, for example, R&D expenditures (excluding those funded by the federal government) have grown from 0.63% of GDP in 1953 to 1.95% of GDP in 2007, i.e. R&D...

The growth literature on the Industrial Revolution has produced novel insights that have changed the way economists think about the issue. Most of the available models, however, focus on the household and do not put industrial activity at the center of the analysis. Consequently, they leave out...

We present an endogenous growth model where innovations are factor-saving and model the choice of technologies in an Overlapping Generations Model where any technology can be adopted paying a cost. Markets are competitive and marginal productivity of factors determines factor prices; therefore,...
