|January 2017||Firm Heterogeneity in Consumption Baskets: Evidence from Home and Store Scanner Data|
with Thibault Fally: w23101
A growing literature has documented the role of firm heterogeneity within sectors in accounting for nominal income inequality. This paper explores the implications for household price indices across the income distribution. Using detailed matched US home and store scanner microdata, we present evidence that rich and poor households source their consumption from different parts of the firm size distribution within disaggregated product groups. We use the microdata to examine alternative explanations, propose a tractable quantitative model with two-sided heterogeneity that rationalizes the observed moments, and calibrate it to explore general equilibrium counterfactuals. We find that larger, more productive firms endogenously sort into catering to the taste of wealthier households, and that ...
|June 2016||Tourism and Economic Development: Evidence from Mexico's Coastline|
with Cecile Gaubert: w22300
Tourism is one of the most visible and fastest growing facets of globalization in developing countries. This paper combines a rich collection of Mexican microdata with a quantitative spatial equilibrium model and a new empirical strategy to learn about the long-run economic consequences of tourism. We begin by estimating a number of reduced-form effects on local economic outcomes in today's cross-section of Mexican municipalities. To base these estimates on plausibly exogenous variation in long-term tourism exposure, we exploit geological and oceanographic variation in beach quality along the Mexican coastline to construct instrumental variables. To guide the estimation of the aggregate implications of tourism, we then write down a spatial equilibrium model of trade in goods and tourism se...
|June 2015||ICT and Education: Evidence from Student Home Addresses|
with Rosa Sanchis-Guarner, Felix Weinhardt: w21306
Governments are making it a priority to upgrade information and communication technologies (ICT) with the aim to increase available internet connection speeds. This paper presents a new empirical strategy to estimate the causal effects of these policies, and applies it to the questions of whether and how ICT upgrades affect educational attainment. We draw on a rich collection of microdata that allows us to link administrative test score records for the population of English primary and secondary school students to the available ICT at their home addresses. To base estimations on exogenous variation in ICT, we notice that the boundaries of usually invisible telephone exchange station catchment areas give rise to substantial and essentially randomly placed jumps in the available ICT across n...
|May 2015||Retail Globalization and Household Welfare: Evidence from Mexico|
with David Atkin, Marco Gonzalez-Navarro: w21176
The arrival of global retail chains in developing countries is causing a radical transformation in the way that households source their consumption. This paper draws on a new collection of Mexican microdata to estimate the effect of foreign supermarket entry on household welfare. The richness of the microdata allows us to estimate a general expression for the gains from retail FDI, and to decompose these gains into several distinct channels. We find that foreign retail entry causes large and significant welfare gains for the average household that are mainly driven by a reduction in the cost of living. About one quarter of this price index effect is due to pro-competitive effects on the prices charged by domestic stores, with the remaining three quarters due to the direct consumer gains fr...
