We assess price dispersion in retail markets and its sources over time. Using a product-detailed price database, we document a consistent divergence of prices over time in retail markets in Uruguay: price dispersion increased by 3.1% in fifteen years. Next, we analyze microeconomic and...

We propose a decomposition of the border effect in international trade by controlling for differences in competition in local markets. An extension of the Hotelling (1929) model shows that the availability of local substitutes increases price dispersion and biases the estimation of the border...

We use micro data collected at the border and at retailers to characterize the effects brought by recent changes in US trade policy - particularly the tariffs placed on imports from China - on importers, consumers, and exporters. We start by documenting that the tariffs were almost fully passed...

We study how within-store price variation changes with inflation, and whether households exploit it to attenuate the inflation burden. We use micro price data for food products sold by 91 large multi-channel retailers in 10 countries between 2018 and 2024. Measuring unit prices within narrowly...

We use a detailed micro dataset on product availability to construct a direct high frequency measure of consumer product shortages during the 2020-21 pandemic. We document a widespread multi-fold rise in shortages in nearly all sectors early in the pandemic. Over time, the composition of...

This paper examines the disparity in default risk between vulnerable and non-vulnerable populations in consumer lending. We merge an exhaustive registry of loans granted in the financial system with microdata on vulnerable individuals applying for social programs. We estimate the sources of this...

In this study we use data on subjective well being and migration in Cuenca, one of the Ecuador's largest cities. We examine the impact of migration on the happiness of the family left behind. We use the propensity score matching estimator to take into account the endogeneity of migration. Our...

This paper quantifies the distributional and poverty effects of national and external trade reform in Brazil using household survey data. We estimate the consumption and labor impact of the Mercosur trade reform following the methodology suggested by Porto (2006). In order to analyze the impact...

Although trade integration has potential benefits for developing countries, it is disputed whether trade liberalization processes are, per se, sufficient for poverty reduction and inequality abatement. Abundant work has analyzed the link between tariff reduction, poverty levels and inequality in...
