American Journal of Agricultural Economics, EarlyView.Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Farm labor scarcity and its uneven impacts on crop producers in the United States
American Journal of Agricultural Economics, EarlyView.Abstract This study is the first to evaluate the impacts of farm labor scarcity on producers in the United States across different crop production systems. Between 2002 and 2017, we disentangle the effects of labor scarcity from the impacts of rising commodity demand, technological change, and supply of other inputs on labor market outcomes.

Firm turnover under asymmetric information: Tanzania's agro‐dealer sector

Using a three‐round census of agro‐dealers in Tanzania's Morogoro Region, we document annual firm entry and exit rates of 33% and 17%, respectively.
