The introduction of new technologies in agriculture can foster structural transformation by freeing workers who find occupation in other sectors. The traditional view is that this reallocation of workers towards manufacturing can lead to industrial development. However, when workers moving to...

We study the impacts of a rural development program designed to boost the income of the smallfarm sector in Nicaragua. Exploiting the random assignment of treatment, we find statistically and economically significant impacts on gross farm income and investment in productive farm capital. Using...

The expansion in farm size is an important contributor to agricultural productivity in developed countries, but the reallocation process is hindered in less developed economies. How do distortions to factor reallocation affect farm dynamics and agricultural productivity? We develop a model of...

Agricultural extension programs often train a few farmers and count on diffusion through social networks for the innovation to spread. However, if markets are imperfectly integrated, this may also inflict negative externalities. In a two-step experiment of an agronomy training program among...

We assess the extent and cost of misallocation in agriculture in less-developed countries comparing the analysis at the plot and farm levels. Using detailed data from Uganda, we show that the plot-level analysis leads to extremely large estimates of reallocation gains, even after adjusting for...

We use a dataset of the entire population of English Parliamentary enclosure acts between 1750 and 1830 to provide the first causal evidence of their impact. Exploiting a feature of the Parliamentary process that produced such legislation as a source of exogenous variation, we show that...

The US Civil War ended in 1865 without the distribution of land or compensation to those formerly enslaved--a decision often seen as a cornerstone of racial inequality. We build a dataset to observe Black households' landholdings in 1880, a key component of their wealth, alongside a sample of...

We assess the effects of a major land policy change on farm size and agricultural productivity using a quantitative model and micro-level data. We study the 1988 land reform in the Philippines that imposed a ceiling on land holdings, redistributed above-ceiling lands to landless and smallholder...
