Over the course of the nineteenth century manufacturing in the United States shifted from artisan shop to factory production. At the same time United States experienced a "transportation revolution", a key component of which was the building of extensive railroad network. Using a newly created...

We assess the CO₂ fertilization effect on US agriculture using spatially-varying CO₂ data from NASA's Orbiting Carbon Observatory-2 (OCO-2) satellite covering the majority of US cropland under actual growing conditions. This study complements the many CO₂ enrichment experiments that have found...

U.S. agriculture was transformed during the 20th century by waves of innovation with mechanical, biological, chemical, and information technologies. Compared with a few decades ago, today's agriculture is much less labor intensive and farms are much larger and more specialized, supplying a...

Extreme heat is the single best predictor of corn and soybean yields in the United States. While average yields have risen continuously since World War II, we find no evidence that relative tolerance to extreme heat has improved between 1950 and 2005. Climate change forecasts project a sharp...

We present a new framework to identify demand and supply elasticities of agricultural commodities using yield shocks - deviations from a time trend of output per area, which are predominantly caused by weather fluctuations. Demand is identified using current-period shocks that give rise to...

The relationships among the weather, agricultural markets, and financial markets have long been of interest to economic historians, but relatively little empirical work has been done. We push this literature forward by using modern drought indexes, which are available in detail over a wide area...

We model the relationship between local agricultural surpluses, nutritional status, and height, and we test the hypothesis that adult height is positively correlated with the local production of nutrition in infancy. We test the hypothesis on two samples of Union Army recruits - one consisting...

This paper employs a stochastic frontier approach to examine how climate change and extreme weather affect U.S. agricultural productivity using 1940-1970 historical weather data (mean and variation) as the norm. We have four major findings. First, using temperature humidity index (THI) load and...

A growing body of economics research projects the effects of global climate change on economic outcomes. Climate scientists often criticize these articles because nearly all ignore the well-established uncertainty in future temperature and rainfall changes, and therefore appear likely to have...
