Economists use micro-based and macro-based approaches to assess the effects of health on economic growth. The micro-based approach tends to find smaller effects than the macro-based approach, thus presenting a micro-macro puzzle regarding the economic return on health. We reconcile these two...

Growth has fallen in the U.S., while firm concentration and profits have risen. Meanwhile, labor's share of national income is down, mostly due to the rising market share of low labor share firms. We propose a theory for these trends in which the driving force is falling firm-level costs of...

The share of the population aged 60 and over is projected to increase in nearly every country in the world during 2005-2050. Population ageing will tend to lower both labor-force participation and savings rates, thereby raising concerns about a future slowing of economic growth. Our calculations...

This paper revisits the relationship between health and growth in light of modern endogenous growth theory. We propose a unified framework that encompasses the growth effects of both the rate of improvement of health and the level of health. Based on cross-country regressions over the period...

This paper evaluates whether the cyclical pattern of fiscal policy can affect growth. We first build a simple endogenous growth model where entrepreneurs can invest either in short-run projects or in long-term growth enhancing projects. Long-term projects involve a liquidity risk which credit...

Increases in the proportion of the working age population can yield a "demographic dividend" that enhances the rate of economic growth. We estimate the parameters of an economic growth model with a cross section of countries over the period 1960 to 1980 and investigate whether the inclusion of...

We explore the question of how political institutions and particularly democracy affect economic growth. Although empirical evidence of a positive effect of democracy on economic performance in the aggregate is weak, we provide evidence that democracy influences productivity growth in different...

Can a country grow faster by saving more? We address this question both theoretically and empirically. In our model, growth results from innovations that allow local sectors to catch up with the frontier technology. In relatively poor countries, catching up with the frontier requires the...

This paper offers empirical evidence that real exchange rate volatility can have a significant impact on long-term rate of productivity growth, but the effect depends critically on a country's level of financial development. For countries with relatively low levels of financial development,...

We analyze an economy where managers engage both in the adaptation of technologies from the world frontier and in innovation activities. The selection of high-skill managers is more important for innovation activities. As the economy approaches the technology frontier, selection becomes more...
