Agriculture may support the local nonagricultural economy in rural areas, though agricultural expansion may also crowd-out nonagricultural activity. On the United States Plains, areas over the Ogallala aquifer experienced windfall agricultural gains when post WWII technologies increased farmers'...

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...

Agricultural development may support broader economic development, though agricultural expansion may also crowd-out local non-agricultural activity. On the United States Plains, areas over the Ogallala aquifer experienced windfall agricultural gains when post-WWII technologies increased farmers'...

Agriculture on the American Great Plains has been constrained by historical water scarcity. After World War II, technological improvements made groundwater from the Ogallala aquifer available for irrigation. Comparing counties over the Ogallala with nearby similar counties, groundwater access...

We investigate the puzzle of microfinance: that loans generate large measured returns for businesses, yet loan take-up is low and the businesses often close. We analyze a randomized trial that bundled microfinance loans with a cheap health insurance policy. Requiring clients to purchase...

Technological innovation in agriculture was substantial during the 20th century. Is "modern" technological control of the environment replacing a "primitive" dependency on natural advantages and disadvantages, or has agricultural production remained persistently dependent on the environment?...

Microfinance institutions have started to bundle their basic loans with other financial services, such as health insurance. Using a randomized control trial in Karnataka, India, we evaluate the impact on loan renewal from mandating the purchase of actuarially-fair health insurance covering...

In the American South, post-bellum economic stagnation has been partially attributed to white landowners' access to low-wage black labor; indeed, Southern economic convergence from 1940 to 1970 was associated with substantial black out-migration. This paper examines the impact of the Great...

This paper examines the historical impact of railroads on the American economy. Expansion of the railroad network may have affected all counties directly or indirectly - an econometric challenge that arises in many empirical settings. However, the total impact on each county is captured by...
