We extend the basic Schumpeterian endogenous growth model by allowing incumbents to undertake innovations to improve their products, while entrants engage in more “radical” innovations to replace incumbents. Our model provides a tractable framework for the analysis of growth driven by both...

Using available data on the distribution of HIV/AIDS prevalence across population groups for four sub-Saharan African countries and transposing this information to household income and expenditure surveys, we simulate the impact of HIV/AIDS on poverty and inequality. We find that the epidemic...

The information technology (IT) revolution has arrived, but how much will it change the world? It has been established that IT is contributing to labor productivity growth through both increases in the levels of IT capital per worker and total factor productivity (TFP) growth in the production...

While production of ICT equipment plays a subordinate role for economic growth in most of these countries, they do benefit from capital deepening arising from falling prices of ICT equipment. Adapting established growth accounting approaches to the data environment of low-income countries, we...

We construct a model where the equilibrium organization of firms changes as an economy approaches the world technology frontier. In vertically integrated firms, owners (managers) have to spend time both on production and innovation activities, and this creates managerial overload, and...

Countries that have pursued distortionary macroeconomic policies, including high inflation, large budget deficits and misaligned exchange rates, appear to have suffered more macroeconomic volatility and also grown more slowly during the postwar period. Does this reflect the causal effect of...

This Paper documents that the rise of (Western) Europe between 1500 and 1850 is largely accounted for by the growth of European nations with access to the Atlantic, and especially by those nations that engaged in colonialism and long distance oceanic trade. Moreover, Atlantic ports grew much...

This paper analyzes the welfare benefits from falling relative prices of IT (information technology) goods across a wide range of countries. We find, using two separate methodologies and datasets, that welfare benefits mainly accrue to users of IT, not their producers, because of falling...

The paper addresses the impact of HIV/AIDS on per capita output and income, with particular emphasis on the role of labor mobility between the formal and informal sectors, and the impact of the epidemic on investment decisions. The study finds that HIV/AIDS affects both the supply of labor and...

This introduces the symposium on economic growth.
