"This paper investigates the impacts of cotton marketing reforms on farm productivity, a key element for poverty alleviation, in rural Zambia. The reforms comprised the elimination of the Zambian cotton marketing board that was in place since 1977. Following liberalization, the sector adopted an...

We exploit substantial variation in land-market institutions across Indian states and detailed micro household-level panel data to assess the effect of distortions in land rental markets on agricultural productivity. We provide empirical evidence that states with more rental-market activity...

Developing countries are characterized by frictions that impede the mobility of workers across occupations and space. We disentangle the role of insecure property rights from other labor mobility frictions for the reallocation of labor from agriculture to non-agriculture and from rural to urban...

This paper integrates local temperature treatment effects and a quantitative macroeconomic model to evaluate the impact of climate change on sectoral reallocation and aggregate productivity. First, I use firm-level data from a wide range of countries to estimate the effect of temperature on...

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...

The achievements in agricultural innovation over the past century have been impressive, supporting large increases in agricultural yields and low food prices. Critical to this success has been sustained public sector investment combined with a decentralized and competitive research system in the...

During the 1850s, land in U.S. farms surged by more than 100 million acres while almost 50 million acres of land were transformed from their raw, natural state into productive farmland. The time and expense of transforming this land into a productive resource represented a significant fraction...

The question we address in this paper is why the Japanese miracle didn't take place until after World War II. For much of the pre-WWII period, Japan's real GNP per worker was not much more than a third of that of the U.S., with falling capital intensity. We argue that its major cause is a...

This paper seeks to explain the U-shaped relationship between farm productivity and farm scale - the initial fall in productivity as farm size increases from its lowest levels and the continuous upward trajectory as scale increases after a threshold - observed across the world and in low-income...

According to national accounts data, value added per worker is much higher in the non-agricultural sector than in agriculture in the typical country, and particularly so in developing countries. Taken at face value, this "agricultural productivity gap" suggests that labor is greatly misallocated...
