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...

Because positive spillovers give investment in innovation a social rate of return several times higher than its internal rate of return to innovators, innovation is chronically underfunded. Recurrent manias, panics and crashes in stock markets inundate "hot" new technologies with capital. To the...

The neoclassical growth accounting model used by the BLS to sort out the contributions of the various sources of growth in the U.S. economy accords a relatively small role to education. This result seems at variance with the revolution in information technology and the emergence of the...

In the aftermath of World War II, the world's economies exhibited very different rates of economic recovery. We provide evidence that those countries that caught up the most with the U.S. in the postwar period are those that also saw an acceleration in the speed of adoption of new technologies....

A great deal of research has been devoted to the effects of technical change on economic growth. Less attention has been given to the factors driving the growth of the technological innovators themselves. This paper examines the case of one of the central contributors to the IT revolution, the...

Incomes per capita have grown dramatically over the past two centuries, but the increase has been unevenly spread across time and across the world. Growth accounting is the principal quantitative tool for understanding this phenomenon, and for assessing the prospects for further increases in...

GDP growth is often measured poorly for countries and rarely measured at all for cities or subnational regions. We propose a readily available proxy: satellite data on lights at night. We develop a statistical framework that uses lights growth to augment existing income growth measures, under...

Economic development in Latin America has trailed most other world regions over the past four decades despite its relatively high initial development and school attainment levels. This puzzle can be resolved by considering the actual learning as expressed in tests of cognitive skills, on which...

Where legal systems and market forces enforce contracts inadequately, vertical integration can circumvent these transaction difficulties. But, such environments often also feature highly interventionist government, and even corruption. Vertical integration might then enhance returns to political...

We provide evidence that the robust association between cognitive skills and economic growth reflects a causal effect of cognitive skills and supports the economic benefits of effective school policy. We develop a new common metric that allows tracking student achievement across countries, over...
