Programs to reduce tra¢ c congestion and air pollution by restricting use of motor vehicles on working days have generally not met with success given existing studies of such programs in a number of cities. We conduct the Örst study of Quito, Ecuadorís three-year-old Pico y Placa program...

This paper takes advantage of a rich firm level data set from Ecuador to analyze the effects of a reform in 2007 that introduced imprisonment for tax evasion and made a firm’s CFO liable for tax-crimes. Our dataset contains actual tax-return and financial-statement information for the universe...

We use firm-level administrative data from Ecuador to study the implications of 'reverse withholding' for firms' tax behavior. Withholding does not affect tax liability of firms, but it may result in a discontinuity in the audit probability around the withholding threshold. Exploiting variation...

The influential contributions of DiNardo, Fortin, and Lemieux (1996), Firpo, Fortin, and Lemieux (2009), Machado and Mata (2005), and Donald, Green, and Paarsch (2000) provide researchers with a useful toolbox to estimate counterfactual distributions of scalar random variables. These techniques...

This paper specifies and estimates a structural model of home seller behavior. The model is an application of search theory to housing and is estimated using method of moments. The estimation method uncovers an analytical closed-form relationship between reduced- form coefficients of hedonic and...

We propose two new indices that measure the evolution of housing market liquidity. The key features of both indices are a) their ability to control for unobserved heterogeneity exploiting repeat listings, b) their use of censored durations (listings that are expired and/or withdrawn from the...

This paper assesses the predictive power of variables that measure market tightness, such as seller's bargaining power and sale probabilities, on future home prices. Theoretical insights from a stylized search-and-matching model illustrate that such indicators can be associated with subsequent...

Sunday birth rates in Ecuador have sharply declined, and the drop is larger among young cohorts in urban areas. These trends are attributed to an increase in cesarean births, which are generally scheduled during regular hospital hours. Multiple rounds of Health Surveys confirm that mothers with...
