Labor informality, common in Latin American economies, is both a cause of low productivity and vulnerability, and a buffer that mitigates job destruction after negative shocks. In the current circumstances, informality is also associated with a higher risk of contagion, thus reducing the willingness of households to get involved in informal activities. To understand and quantify these mechanisms, we propose an SIR model featuring a dual labor market, where households imperfectly substitute informal and formal consumption, and calibrate it to Colombian and Peruvian data.

This paper exploits a natural experiment to study the extent to which attitudes towards trade reflect economic fundamentals. In 2007, Costa Rica was the first developing country to put a free trade agreement (FTA) to a national referendum; with only one question on the ballot, 60% of Costa Rican adult citizens casted a vote on whether they wanted a trade agreement (CAFTA-DR) to be ratified, or not.

Protecting caregivers and children from effects of violence, toxic stress, and deficits in maternal care is a key challenge in fragile and conflict-affected settings. In this paper we report the results from a randomized trial of Semillas de Apego, a community-based psychosocial model for mothers of young children among families affected by violence and forced displacement. The model aims to promote maternal mental health as an outcome itself but also as a pathway to foster the healthy child-mother emotional bonds and early childhood development.

We estimate the impact of COVID-19 on business failures for small and medium sized enterprises (SMEs) using firm-level data in seventeen countries. Absent government support, the failure rate of SMEs would have increased by 9.1 percentage points, representing 4.6 percent of private sector employment. Resulting non-performing loans are modest, decreasing the riskweighted common equity Tier-1 capital ratio from 14.1 to 12 percent. Government support limited to “at-risk” firms would have low fiscal costs (0.8% of GDP).

The inflow of migrants from El Salvador to the United States has increased persistently since 1980.  In spite of the intensification of immigration policies in the U.S.

We consider the effects of climate change on seasonally migrant populations that herd livestock – i.e., transhumant pastoralists – in Africa. Traditionally, transhumant pastoralists benefit from a cooperative relationship with sedentary agriculturalists whereby arable land is used for crop farming in the wet season and animal grazing in the dry season. Droughts can disrupt this arrangement by inducing pastoral groups to migrate to agricultural lands before the harvest, causing conflict to emerge.

We explore quantitatively the possibility of multiple equilibria in a model of sovereign debt crises. The source of multiplicity is the one identified by Calvo (1988). This type of multiplicity has been at the heart of the policy debate through the European sovereign debt crisis. Key for multiplicity in the model is a stochastic process for output featuring long periods of either high or low growth. We calibrate the output process in the model using data for southern European countries that were exposed to the debt crisis. We also calibrate the model to Brazil and Argentina.

Recent research shows prices are insensitive to local demand conditions because national chains charge geographically uniform prices. We examine the price response to local cost shocks, including 68 excise tax changes, 76 sales tax changes, and other geographically-based cost differences, using data on 35,151 retail stores in 143 multistate chains. We find local cost shocks are passed-through to local prices, with no spillovers to unaffected stores in otherwise affected chains, and at similar rates for national and local chains.

What are the impacts of regularization on migrant’s lives? This study examines the effects of the PEP visa, an opportunity for regularization for half a million Venezuelan refugees in Colombia. We collect a survey of 3,455 migrant families and leverage four identification strategies to assess the effects of the program in migrant’s life outcomes. Causal effects are estimated using a fuzzy regression discontinuity design that compares the wellbeing of migrants who arrived to Colombia close to June 8th, 2018 (eligible for the program) and those who arrived later (not eligible).
