The sharing economy for a wide range of goods and services is expanding across the world. To direct the benefits from sharing capital services towards small-scale producers, governments in the developing world are increasingly intervening in fast-growing mechanization rental markets. However,...

This article provides an overview of the literature on mobility in developing countries. Explicit distinctions are drawn between directional and non-directional measures, absolute and relative measures, and combinations thereof. We note that the scarcity of panel data has hindered the...

Several recent studies have examined the tendency of regions within a nation to exhibit long-term convergence in per capita income levels. Barro and Sala-i-Martin (1991, 1992, 1995) have found a tendency towards convergence among the U.S. states, among Japanese prefectures, and among regions...

W. Arthur Lewis argued that a new international economic order emerged between 1870 and 1913, and that global terms of trade forces produced rising primary product specialization and de-industrialization in the poor periphery. More recently, modern economists argue that volatility reduces growth...

This paper focuses on the contribution to recent narrowing of the gap between Northern and Southern economies in GDP/capita, shares in world trade and market capitalization attributable both jointly and single to China, India, and Brazil (the three currently largest rapidly growing Southern...

We study the spatial expansion of banks in response to banking deregulation in the 1980s and 90s. During this period, large banks expanded rapidly, mostly by adding new branches in new locations, while many small banks exited. We document that large banks sorted into the densest markets, but...

We measure the importance of increasing returns to scale and trade in medical services. Using Medicare claims data, we document that "imported" medical care -- services produced by a medical provider in a different region -- constitute about one-fifth of US healthcare consumption. Larger regions...

We study the history and geography of wealth accumulation in the US, using newly collected historical property tax records since the early 1800s. The US General Property Tax was a comprehensive tax on all types of property (real, personal, and financial), making it one of the first "wealth...

We introduce new measurement tools to understand the sources of earnings differences across space. Based on the natural language employers use in job vacancy text, we develop granular measures of job tasks and of worker specialization. We find that jobs in larger commuting zones involve greater...

A unilateral carbon tax trades off the distortionary costs of taxation and the future gains from slowing down global warming. Because the cost is local and immediate, whereas the benefit is global and delayed, this tradeoff tends to be unfavorable to unilateral carbon taxes. We show that this...
