This paper examines the temperature-mortality relationship over the course of the twentieth-century United States both for its own interest and to identify potentially useful adaptations for coming decades. There are three primary findings. First, the mortality impact of days with mean temperature exceeding 80°F declined by 75 percent. Almost the entire decline occurred after 1960. Second, the diffusion of residential air conditioning explains essentially the entire decline in hot day–related fatalities. Third, using Dubin and McFadden’s discrete-continuous model, the present value of US consumer surplus from the introduction of residential air conditioning is estimated to be $85–$185 billion (2012 dollars).

Hurricanes are the most destructive natural disasters in the United States. The record of economic damage from hurricanes shows a steep positive trend dominated by increases in wealth. It is necessary to account for temporal changes in exposed wealth, in a process called normalization, before we can compare the destructiveness of recorded damaging storms from different areas and at different times. Atmospheric models predict major hurricanes to get more intense as Earth warms, and we expect this trend to eventually emerge above the natural variability in the record of normalized damage. However, the evidence for an increasing trend in normalized damage since 1900 has been controversial. In this study, we develop a record of normalized damage since 1900 based on an equivalent area of total destruction. Here, we show that this record has an improved signal-to-noise ratio over earlier normalization schemes based on calculations of present-day economic damage. Our data reveal an emergent positive trend in damage, which we attribute to a detectable change in extreme storms due to global warming. Moreover, we show that this increasing trend in damage can also be exposed in existing normalized damage records by looking at the frequency of the largest damage events. Our record of normalized damage, framed in terms of an equivalent area of total destruction, is a more reliable measure for climate-related changes in extreme weather, and can be used for better risk assessments on hurricane disasters.

Colonial powers typically organized economic activity in the colonies to maximize their economic returns. While the literature has emphasized long-run negative economic impacts via institutional quality, the changes in economic organization implemented to spur production historically could also directly influence economic organization in the long-run, exerting countervailing effects. We examine these in the context of the Dutch Cultivation System, the integrated industrial and agricultural system for producing sugar that formed the core of the Dutch colonial enterprise in 19th century Java. We show that areas close to where the Dutch established sugar factories in the mid-19th century are today more industrialized, have better infrastructure, are more educated, and are richer than nearby counterfactual locations that would have been similarly suitable for colonial sugar factories. We also show, using a spatial regression discontinuity design on the catchment areas around each factory, that villages forced to grow sugar cane have more village-owned land and also have more schools and substantially higher education levels, both historically and today. The results suggest that the economic structures implemented by colonizers to facilitate production can continue to promote economic activity in the long run, and we discuss the contexts where such effects are most likely to be important.

With weak law-enforcement institutions, a positive shock to the value of natural resources may increase demand for private protection and opportunities for rent appropriation through extortion, favouring the emergence of mafia-type organisations. We test this hypothesis by investigating the emergence of the mafia in twentieth century Sicily, where a severe lack of state property-rights enforcement coincided with a steep rise in international demand for sulphur, Sicily's most valuable export commodity. Using historical data on the early incidence of mafia activity and on the distribution of sulphur reserves, we document that the mafia was more present in municipalities with greater sulphur availability.

We use the late nineteenth-century establishment of agricultural experiment stations at preexisting land-grant colleges across the United States to estimate the importance of proximity to research for productivity growth. Our analysis reveals that proximity to newly opened permanent stations affected land productivity for about 20 years and then subsequently declined until becoming largely absent today. We conclude that spatial frictions substantially reduced the rate of return to public research spending in the late nineteenth and early twentieth centuries, but such frictions significantly diminished as extension programs, automobiles, and telephones made it easier for discoveries to reach farther farms.

What are corporations, and to whom are they responsible? Anthropologist Marina Welker draws on two years of research at Newmont Mining Corporation’s Denver headquarters and its Batu Hijau copper and gold mine in Sumbawa, Indonesia, to address these questions. Against the backdrop of an emerging Corporate Social Responsibility movement and changing state dynamics in Indonesia, she shows how people enact the mining corporation in multiple ways: as an ore producer, employer, patron, promoter of sustainable development, religious sponsor, auditable organization, foreign imperialist, and environmental threat. Rather than assuming that corporations are monolithic, profit-maximizing subjects, Welker turns to anthropological theories of personhood to develop an analytic model of the corporation as an unstable collective subject with multiple authors, boundaries, and interests. Enacting the Corporation demonstrates that corporations are constituted through continuous struggles over relations with—and responsibilities to—local communities, workers, activists, governments, contractors, and shareholders.

Building on the idea that members of religious communities insure each other against some idiosyncratic risks, we argue that religious communities should be more widespread where populations face greater common risk. Our theoretical argument builds on idiosyncratic and common risks aggravating each other. When this is the case, individuals have a greater incentive to mutually insure against idiosyncratic risk when greater common risk makes the worst case scenario of bad realizations of common and idiosyncratic risks more likely. Our empirical analysis exploits common rainfall risk as a source of common county-level agricultural risk in the 19th-century United States. We find that a greater share of the population was organized in religious communities in counties with greater common agricultural risk, holding expected agricultural output constant. The link between rainfall risk and membership in religious communities is stronger among more agricultural counties and counties exposed to greater rainfall risk during the growing season. We also find that among the historically more agricultural counties, more than 1/3 of 19th-century differences in religious membership associated with rainfall risk persist to the turn of the 21st century.

This paper combines panel data on monthly mortality rates of US states and daily temperature variables for over a century (1900-2004) to explore the regional evolution of the temperature-mortality relationship and documents two key findings. First, the impact of extreme heat on mortality is notably smaller in states that more frequently experience extreme heat. Second, the difference in the heat-mortality relationship between hot and cold states declined over 1900-2004, though it persisted through 2004. Continuing differences in the mortality consequences of hot days suggests that health motivated adaptation to climate change may be slow and costly around the world.

Agriculture on the American Plains has been constrained historically by water scarcity. Post-WWII technologies enabled farmers over the Ogallala aquifer to extract groundwater for large-scale irrigation.Comparing counties over the Ogallala with nearby similar counties, groundwater access increased agricultural land values and initially reduced the impact of droughts. Over time, land use adjusted toward water intensive crops and drought sensitivity increased. Viewed differently, farmers in nearby water-scarce areas maintained lowervalue drought-resistant practices that fully mitigate naturally higher drought sensitivity. The evolving impact of the Ogallala illustrates the importance of water for agricultural production, but also the large scope for agricultural adaptation to groundwater and drought.
