This paper focuses on the question of income convergence among countries. While the methodology used to determine convergence differs from the common cross-sectional approach, it corroborates Baumol's finding of a convergence club among the world's wealthiest countries. It also shows that there...

In the political debate people express the idea that immigrants are good because they can help pay for the old. The paper explores this idea in a dynamic political-economy setup. We characterize sub-game perfect Markov equilibria where immigration policy and pay-as-you-go (PAYG) social security...

This paper focuses on one possible explanation for the empirical evidence of: (a) income convergence among the world’s poorest countries and among its wealthiest countries; and (b) income divergence among most of the remaining countries. The model incorporates the assumption of subsistence...

For decades, the prevailing sentiment among economists was that growth rates remain constant over the long run. Kaldor considered this to be one of the six important `stylized facts' that theory should address, and until the emergence of endogenous growth models, this was a fundamental feature...

This is an attempt to derive broad, strategic lessons from the diverse experience with economic growth in last 50 years. The paper revolves around two key arguments. One is that neo-classical economic analysis is a lot more flexible than its practitioners in the policy domain have generally...

Some channels through which increased inflation tends to reduce economic growth, and vice versa, are studied within a simple model incorporating money into an optimal growth framework with constant returns to capital. The model includes the potential impact of inflation on: (a) saving through...

We investigate the impact of within-country spatial concentration of economic activity on country-level growth, using cross-section OLS and dynamic panel GMM estimation. Agglomeration is measured alternatively through measures of urbanization and through indices of spatial concentration based on...

The paper reviews the economic performance of the Republic of Ireland since 1945. Its focus is comparative: Ireland's record is assessed against the evidence in OECD and Penn Mark V datasets for a `convergence club' of European economies, and is found wanting. The comparison confirms that the...

We model technological and financial innovation as reflecting the decisions of profit maximizing agents and explore the implications for economic growth. We start with a Schumpeterian endogenous growth model where entrepreneurs earn monopoly profits by inventing better goods and financiers arise...

We study how barriers to competition - such as, restrictions to business start-up and strict enforcement of covenants or IPR - affect the investment in knowledge capital when contracts are not enforceable. These barriers lower the competition for human capital and reduce the incentive to...
