Efforts to anticipate how climate change will affect future food availability can benefit from understanding the impacts of changes to date. We found that in the cropping regions and growing seasons of most countries, with the important exception of the United States, temperature trends from 1980 to 2008 exceeded one standard deviation of historic(More)
The 1930's American Dust Bowl was an environmental catastrophe that greatly eroded sections of the Plains. Analyzing new data collected to identify low-, medium-, and high-erosion counties, the Dust Bowl is estimated to have immediately, substantially , and persistently reduced agricultural land values and revenues. During the Depression and through at(More)
This paper measures the economic impact of climate change on US agricultural land by estimating the effect of random year-to-year variation in temperature and precipitation on agricultural profits. The preferred estimates indicate that climate change will increase annual profits by $1.3 billion in 2002 dollars (2002$) or 4 percent. This estimate is robust(More)
There has been a lively debate about the potential impact of global climate change on U.S. agriculture. Most of the early agro-economic studies predict large damages (see, (1994)-hereafter MNS-propose a new approach: using the variation in temperature and precipitation across U.S. counties to estimate a reduced form hedonic equation with the value of(More)
* We thank David Bradford for initiating a conversation that ultimately led to this paper. ABSTRACT This paper measures the economic impact of climate change on US agricultural land. We replicate the previous literature's implementation of the hedonic approach and find that it produces estimates of the effect of climate change that are very sensitive to(More)
Enrivonmental challenges are projected to increase through the 21st century, and it is natural to consider how new technologies change agricultural dependence on the environment. Technological innovation in agriculture was substantial during the 20th century. Is there a progression toward " modern " technological control of the environment that replaces a "(More)
We show how yield shocks (deviations from a time trend), which are likely attributable to random weather fluctuations, can facilitate estimation of both demand and supply elasticities of agricultural commodities. We identify demand using current-period shocks that give rise to exogenous shifts in supply. We identify supply using past yield shocks, which(More)
Despite the existence of a large and growing literature on the potential impact of climate change on agriculture, there still exists some disagreement about the magnitude and even the sign. Our own research suggests that the impact on U.S. agriculture is likely to be strongly negative, based on a series of studies in which we link farmland values to climate(More)
This paper uses newly available data on plant level regulatory status linked to the Census Longitudinal Business Database (LBD) to measure the impact of changes in county level environmental regulations on plant and sector employment levels. Estimates from a variety of specifications suggest a strong connection between changes in environmental regulatory(More)
This paper provides an introduction to climate data sets, climate models, and the output they provide. We identify five major issues related to the use of gridded historical weather products and climate model output: Spatially specific prediction error due to the coarse resolution of climate model output; spatially varying correlations between different(More)
