Have rich countries improved their environments by importing polluting goods? No, the mix of goods imported has shifted towards those from cleaner industries, not dirtier. Has pollution worsened in poor countries manufacturing goods for export to rich ones? That depends. Emissions intensities for similar industries are higher in poor countries, which means that even balanced trade causes more pollution there, even for the same goods. And proportional growth in trade has increased that gap. Whether we should consider that to be “outsourcing pollution” is debatable. Have environmental regulations enacted by rich countries caused either of the first two changes? No, the evidence does not show that regulations cause outsourcing.

The model of compensating wage differentials is among the cornerstone models of equilibrium wage determination in labor economics. However, empirical estimates of compensating differentials have faced persistent credibility challenges. This article summarizes the Rosen model of compensating differentials and chronicles the advances, setbacks, and lessons learned from empirical studies. The progression from cross-sectional to panel models alleviated biases caused by unobserved human capital but yielded new insights into the importance of other biases, including those caused by labor market frictions and endogenous job mobility. I discuss recent approaches that use matched employer-employee data and quasi-random variation in job amenities to address some of these challenges. I then present two examples of applications of compensating differentials: the evaluation public health and safety policies that rely on the value of statistical life, and the measurement and interpretation of earnings inequality.

This paper documents how US firms organize goods production across firm and country boundaries. Most US firms that perform physical transformation tasks in-house using foreign manufacturing plants in 2007 also own US manufacturing plants; moreover, manufacturing comprises their main domestic activity. By contrast, “factoryless goods producers” outsource all physical transformation tasks to arm's-length contractors, focusing their in-house efforts on design and marketing. This dis tinct firm type is missing from standard analyses of manufacturing, growing in importance, and increasingly reliant on foreign suppliers. Physical transformation “within-the-firm” thus coincides with substantial physical transformation “within-the-country ,” whereas its performance “outside-the-firm” often also implies “outside-the-country.” Despite these differences, factoryless goods producers and firms with foreign and domestic manufacturing plants both employ relatively high shares of US knowledge workers. These patterns call for new models and data to capture the potential for foreign production to support domestic innovation, which US firms leverage around the world.

Jurisdictions adopt climate policies that vary in terms of both ambition and policy approach, with some pricing carbon and others subsidizing clean production. We distinguish two types of policy spillovers from these diverse approaches. First, when countries have different levels of climate ambition, free-riders benefit at the expense of more committed countries. Second, when countries pursue different approaches, carbon-intensive producers within cost-imposing jurisdictions are at a relative competitive disadvantage compared with producers in subsidizing jurisdictions. Carbon border adjustments and climate clubs respond to these spillovers, but when countries have divergent approaches, one policy alone cannot address both spillovers. We also consider the policy dynamics arising from carbon border adjustments and climate clubs; both have the potential to encourage upward harmonization of climate policy, but come with risks. Further, the pressures of international competition may result in subsidy races, with attendant risks and benefits.

Reductions in greenhouse gas emissions are a global public good, which makes it efficient to act globally when addressing this challenge. We lay out several reasons that high-income countries seeking to mitigate climate change might have greater impact if they invest their resources in opportunities in low- and middle-income countries. Specifically, some of the easiest and cheapest options have already been tapped in high-income countries, land and labor costs are lower in low- and middle-income countries, it is cheaper to build green than to retrofit green, and global targeting matters in integrated economies. We also discuss economic counterarguments such as the challenge of monitoring emissions levels in low- and middle-income countries, ethical considerations, the importance of not double-counting mitigation funding as development aid, and policy steps that might help realize this opportunity.

Mental illnesses affect roughly 20 percent of the US population. Like other health conditions, mental illnesses impose costs on individuals; they also generate costs that extend to family members and the larger society. Care for mental illnesses has evolved quite differently from the rest of health care sector. While medical care in general has seen major advances in the technology of treatment this has not been the case to the same extent for the treatment of mental illnesses. Relative to other illnesses, the cost of care for mental illnesses has grown more slowly and the social cost of illness has grown more rapidly. In this essay we offer evidence about the forces underpinning these patterns and emphasize the challenges stemming from the heterogeneity of mental illnesses. We examine institutions and rationing mechanisms that affect the ability to make appropriate matches between clinical problems and treatments. We conclude with a review of implications for policy and economic research.

What do recent advances in economic geography teach us about the spatial distribution of economic activity? We show that the equilibrium distribution of economic activity can be determined simply by the intersection of labor supply and demand curves. We discuss how to estimate these curves and highlight the importance of global geography—the connections between locations through the trading network—in determining how various policy relevant changes to geography shape the spatial economy.

In the early part of the 20th century the disease pellagra, now almost unknown, affected and killed thousands of people in the United States. Some claimed it was an infection, while others maintained it was due to a dietary deficiency. The economist Edgar Sydenstricker (1881-1936), who was a member of a US Public Health Service team examining the disease, argued it was critical to understand how pellagra varied by levels of income. Collecting survey data, he realized equivalence scales were needed to adjust household incomes. His research demonstrated that there was a strong negative correlation between the incidence of pellagra and equivalized household income. Further analysis of the dietary differences between households suggested that a dietary deficiency associated to a restricted availability of animal protein food was the cause of pellagra. This was confirmed more than a decade later when a deficiency of vitamin B-3 was identified as the cause.
