Keeping Pace or Falling Behind? The Depth of Latin American Trade Agreements
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This article examines whether Latin American countries are keeping pace with global trends in trade agreement depth or falling behind. Using 681 agreements (1970–2019), we develop the Depth Index of Trade Agreements (DITA) to weight provisions endogenously through factor analysis based on co‐occurrence patterns.

Chinese Trade Competition and Rural Mexican Migration
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT China's accession to the World Trade Organization in 2001 reshaped global trade, reducing U.S. demand for Mexican manufactured goods and weakening Mexico's manufacturing employment. This study estimates how this trade‐induced decline affected migration and employment decisions among rural Mexicans.

Temporary Programs, Lasting Questions: Ad Hoc Assistance in the U.S. Farm Safety Net
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT Large ad hoc assistance programs have returned to U.S. farm policy since 2017, operating alongside a more developed safety net built around federally subsidized crop insurance, Title I commodity programs, and standing disaster assistance. This paper reviews the renewed use of ad hoc assistance, documents its recent scale using USDA data, and ...
