Assess students' ability to analyze the effects of NAFTA-era trade liberalization (1994–2010) on Mexico’s income inequality and labor markets. Items should require interpretation of changes in wage distribution, sectoral employment (manufacturing vs. agriculture), regional and urban-rural impacts, informal sector dynamics, migration and skill premiums; evaluate empirical strategies (difference-in-differences, decomposition, microdata analysis), interpret evidence from Mexican surveys and national accounts, and critique causal claims and policy implications.
