In the last decade, economists have produced a considerable body of research suggesting that the historical origin of a country's laws is highly correlated with a broad range of its legal rules and regulations, as well as with economic outcomes. We summarize this evidence and attempt a unified...

We present new data on the regulation of entry of start-up firms in 75 countries. The data set contains information on the number of procedures, official time, and official cost that a start-up must bear before it can operate legally. The official costs of entry are extremely high in most...

In many countries, banks lend to firms controlled by the bank?s owners. We examine the benefits of related lending using a newly assembled dataset for Mexico. Related lending is prevalent (20% of commercial loans) and takes place on better terms than arm?s-length lending (annual interest rates...

Conventional analysis in the trade-industrial-organization literature suggests that, when a country has some market power over an imported good, some small level of protection must be welfare improving. This is essentially a terms-of-trade argument that is reinforced if the imported goods are...

We mailed letters to non-existent business addresses in 159 countries (10 per country), and measured whether they come back to the return address in the US and how long it takes. About 60% of the letters were returned, taking over 6 months, on average. The results provide new objective...

We investigate the determinants of regional development using a newly constructed database of 1569 sub-national regions from 110 countries covering 74 percent of the world's surface and 96 percent of its GDP. We combine the cross-regional analysis of geographic, institutional, cultural, and...

Corn prices increased sharply in the summer of 2012 due to expected production shortfalls in the United States, which produces roughly 40% of the world's corn. A heat wave in July adversely affected corn production. We extend earlier statistical models of county-level corn yields in the Eastern...

It is well documented that, in the presence of substantial fixed costs, markets offer preference majorities more variety than preference minorities. This fact alone, however, does not demonstrate the market outcome is in any way biased against preference minorities. In this paper, we clarify the...

The recent financial crisis in Indonesia has resulted in dramatic price increases. Using very recent data, we investigate whether these price increases have impacted the cost-of-living of poor households in a disproportionately harsh way. We find that the poor have indeed been hit hardest. Just...

We consider nonparametric identification in models of differentiated products markets, using only market level observables. On the demand side we consider a nonparametric random utility model nesting random coefficients discrete choice models widely used in applied work. We allow for...
