We study panel data estimators based on a discretization of unobserved heterogeneity when individual heterogeneity is not necessarily discrete in the population. We focus on two-step grouped-fixed effects estimators, where individuals are classified into groups in a first step using kmeans...

The bootstrap is a convenient tool for calculating standard errors of the parameters of complicated econometric models. Unfortunately, the fact that these models are complicated often makes the bootstrap extremely slow or even practically infeasible. This paper proposes an alternative to the...

We study what happens to identified shocks and to dynamic responses when the data generating process features q disturbances but q1 q variables are used in an empirical model. Identified shocks are linear combinations of current and past values of all structural disturbances and do not...

This paper investigates the concentration of access to safe water across income levels in Bolivia. In particular, it focuses on how privatisation has changed coverage, affordability and the concentration of access to water on the part of the poor. We compare the performance of cities in which...

This paper uses microdata from Brazilian natality and mortality vital statistics between 2000 and 2010 to estimate the impact of in-utero exposure to local violence - measured by homicide rates - on birth outcomes. The estimates show that exposure to violence during the first trimester of...

This paper uses newly available data to describe the distribution of crime victimization and other criminal activities (including drug trafficking and corruption) around the world. The paper then documents a negative (positive) correlation between measures of criminal activity and happiness and...

This study tests whether individuals who grow up with parents on welfare benefits are themselves more (or less) likely to be welfare recipients as young adults, compared to individuals who grow up in non-welfare households. We use the sibling difference method to identify causal effects...

This article analyzes the relationship between abortion and female education. It provides new empirical evidence from sub-Saharan Africa to show that more liberal abortion policies are associated with a higher female secondary school enrollment. It is assumed in the model that easier access to...

We study the intergenerational transmission of cognitive and non-cognitive abilities between parents and sons using population-wide enlistment data. Conscripts are evaluated at the same age and with comparable methods across cohorts, and we correct for measurement error bias in fathers' ability...

Asian Americans faced a disproportionately larger surge in unemployment rates than other racial and ethnic groups during the Covid-19 pandemic. While existing literature typically examines labor demand channels to explain this, we instead explore a labor supply channel. Our hypothesis is that...
