To what extent do national borders and national currencies impose costs that segment markets across countries? To answer this question we use a dataset with product level retail prices and wholesale costs for a large grocery chain with stores in the U.S. and Canada. We develop a model of pricing...

We propose a new sufficient statistic to measure the gains from trade in models where the extensive margin trade elasticity is not necessarily constant. This statistic is a function of one data moment, the market share of continuing domestic products, and one parameter, the elasticity of...

Most trade is invoiced in very few currencies. Yet, standard models assume prices are set in either the producer's or destination's currency. We present instead a ‘dominant currency paradigm' with three key features: pricing in a dominant currency, pricing complementarities, and imported input...

Standard models of hierarchy assume that agents and middle managers are better informed than principals about how to implement a particular task. We estimate the value of the informational advantage held by supervisors – middle managers – when ministerial leadership – the principal –...

While bans against child labor are a common policy tool, there is very little empirical evidence validating their effectiveness. In this paper, we examine the consequences of India's landmark legislation against child labor, the Child Labor (Prohibition and Regulation) Act of 1986. Using data...

Recent research has pointed to large gaps in labor productivity between the agricultural and nonagricultural sectors in low-income countries, as well as between workers in rural and urban areas. Most estimates are based on national accounts or repeated cross-sections of micro-survey data, and as...

How much do calorie requirements vary across households and how do they affect food consumption patterns? Since caloric intake is a widely-used indicator of poverty and welfare, investigating changes in caloric requirements and food consumption patterns is important, especially for the poor....

How do firms in high-income countries adjust to emerging market competition? We estimate how a representative panel of Canadian firms adjusts innovation activities, business strategies, and exit in response to large increases in Chinese imports between 1999 and 2005. On average, process...

In 2009 and 2010, China undertook a 4 trillion Yuan fiscal stimulus, roughly equivalent to 12 percent of annual GDP. The "fiscal" stimulus was largely financed by off-balance sheet companies (local financing vehicles) that borrowed and spent on behalf of local governments. The off-balance sheet...

The positive correlation between PPP investment rates and PPP income levels across countries is one of the most robust findings of the empirical growth literature. We show that this relationship is almost entirely driven by differences in the price of investment relative to output across...
