Video Series on Linear Panel Event-Study Designs
This paper introduces the xtevent package for estimating and visualizing policy effects in linear panel event-study designs. It builds on recent methodological advances from Freyaldenhoven et al. (Forthcoming) to allow for flexible treatments, pre-trend adjustments, and more informative event-study plots. The package is designed to make best practices in estimation and visualization accessible to applied researchers.

Using matched employer-employee data from 2004–2018, this paper decomposes wage dispersion in Mexico into worker, workplace, and sorting components. We find that while overall wage inequality remained stable, the role of sorting and workplace effects grew, particularly in less-developed regions. By the end of the period, workplace characteristics contributed as much to wage variance as worker characteristics.

We study the simultaneous doubling of the minimum wage and halving of the VAT on Mexico’s northern border in 2019. While the minimum wage hike pushed prices up, the VAT cut more than offset this effect, leading to lower average prices overall. The degree of labor informality in production helps explain variation in price responses across goods.

Using an unexpected rise in Colombia’s real minimum wage in 1999, this paper estimates its effects on wages and employment across sectors. Minimum wage increases raised earnings near the bottom of the distribution in both formal and informal sectors—more strongly in the former—suggesting partial compliance and reference-wage behavior.

This paper evaluates Latin America’s fiscal performance over the 2000s decade, highlighting both progress and persistent challenges. While countries earned solid marks for countercyclical responses to the Great Recession, many failed to normalize their fiscal positions afterward. Without corrective reforms, the decade’s “C” grade could slip further, but a clear path to fiscal sustainability remained within reach.

This paper estimates demand systems for Colombian households using 2006–2007 survey data, examining spending behavior across income groups. We find stable food expenditure elasticities over time, but significant variation across income quintiles. Declining elasticities for health, education, and transport suggest these goods have become necessities, likely reflecting past policy efforts.

This paper defines local labor markets in Mexico by grouping economically integrated municipalities, following international best practices. It links these markets to INEGI census data from 1990 to 2020, creating a valuable resource for labor market research. The resulting framework enables more accurate analysis of local labor market dynamics.

Unlike trends seen in many developed cities, Mexico City’s housing price gradient remained stable during the COVID-19 pandemic. Using data from 2019 to 2022, we find no significant change in the relationship between housing prices and distance to the center. Limited remote work, credit constraints, and distinct pandemic policies may explain this divergence.

This paper introduces a method to measure spatial mismatch that accounts for both transportation and opportunity costs. Applied to Medellín (2012–2017), the analysis shows rising spatial mismatch overall—driven largely by declining job accessibility via private transport. Public transit investments may have helped offset this trend for lower-income commuters.

This paper studies how Colombian households adjust spending after health shocks, finding a trade-off between food and health expenditures. The extent of this adjustment varies by social protection access, job formality, and rural or urban setting. Rural and informal households bear the greatest burden, highlighting the protective role of formal employment and strong institutions.

This paper examines how informality shapes the relationship between city size and labor market matching in Mexico. While larger cities typically enhance assortative matching, this effect is muted in Mexico’s formal sector, where informality is widespread. We find that cities with larger informal sectors exhibit weaker matching patterns in their formal labor markets.

This paper studies the effects of a subway expansion in Santiago, Chile, on local labor market outcomes. The analysis shows that improved transit access led to job relocations and wage changes consistent with reduced labor market power by firms. A spatial equilibrium model finds that accounting for these monopsony effects amplifies the welfare gains of the infrastructure investment.

This paper evaluates a hiring tax credit program in North Carolina using a regression discontinuity design based on county-level distress rankings. We find that a $9,000 credit significantly reduces unemployment by nearly 0.5 percentage points and raises employment by about 3%. These results suggest that well-targeted hiring credits can meaningfully improve labor market outcomes in distressed areas.

Multidimensional measures of poverty have become standard as complementary indicators of poverty in many countries. This paper proposes an application of existing methodologies that decompose welfare aggregates -based on counterfactual simulations- to break up the changes of the multidimensional poverty headcount into the variation attributed to each of its dimensions.

We study how labor regulation enforcement affects firms and workers in Mexico’s manufacturing sector. Inspections lead to better compliance—more training, fewer accidents, and fewer repeat violations—and boost employment by around 4%. The results suggest that enforcement can curb monopsonistic practices and improve both working conditions and labor supply.

We analyze how the pandemic shifted traveler preferences in Mexico’s Airbnb market using hedonic price models. Valuation for amenities tied to remote work, open spaces, and reduced contact—like workspaces, beach fronts, and private areas—rose significantly during COVID-19. These changes occurred despite relatively light tourism and mobility restrictions in the country.
