We develop a statistical framework to use satellite data on night lights to augment official income growth measures. For countries with poor national income accounts, the optimal estimate of growth is a composite with roughly equal weights on conventionally measured growth and growth predicted...

Population aging is a global phenomenon that influences not only the industrialized countries of Asia and the West, but also many middle- and low- income countries that have experienced rapid fertility decline and achieved long life expectancies. This book explores how workers and consumers are...

GDP growth is often measured poorly for countries and rarely measured at all for cities. We propose a readily available proxy: satellite data on lights at night. Our statistical framework uses light growth to supplement existing income growth measures. The framework is applied to countries with...

We model growth and technology transfer in a world where technologies are specific to particular combinations of inputs. Unlike the usual specification, our model does not imply that an improvement in one technique for producing a given good improves all other techniques for producing that good....
