We examine a generalized version of Flam and Helpmanacirc;euro;TMs (1987) model of vertical differentiation that maps cross-country differences in income distributions to variations in import variety and price distributions. The theoretical predictions are examined and confirmed using micro data...

We construct a synthetic panel of household expenditures from the Consumer Expenditure Survey (CEX) and use the Quadratic Almost Ideal Demand System to estimate expenditure shares and income elasticities of demand that vary by good-income-time. We show that the size and distribution of income...

We collect extensive data on worldwide trade by transportation mode and use this to provide detailed comparisons of the greenhouse gas emissions associated with output versus international transportation of traded goods. International transport is responsible for 33 percent of world-wide...

In this paper we address two questions. First, how do changes in demand for work affect workers' health? Second, how do we translate these health effects into meaningful economic terms so that we can compare the income gains associated with increased demand for work with the pain of adverse...

We survey the recent empirical literature on the effects of offshoring on wages, employment and displacement. We start with the measurement of offshoring, focusing on the use of imported inputs that could have been produced by the importing firm. We overview key theories related to offshoring...

Developing countries pay substantially higher transportation costs than developed nations, which leads to less trade and perhaps lower incomes. This paper investigates price discrimination in the shipping industry and the role it plays in determining transportation costs. In the presence of...

We estimate how offshoring and exporting affect wages by skill type. Our data match the population of Danish workers to the universe of private-sector Danish firms, whose trade flows are broken down by product and origin and destination countries. Our data reveal new stylized facts about...

A large and growing share of international trade is carried on airplanes. Air cargo is many times more expensive than maritime transport but arrives in destination markets much faster. We model firms' choice between exporting goods using fast but expensive air cargo and slow but cheap ocean...
