Analysis of household food consumption patterns and welfare requires knowledge of household demand responses to changes in price and income. Estimation of the price and expenditure elasticities requires detailed data on household purchases and prices, which are often not available in many...

This paper evaluates the performance of the Colombian electricity distribution companies during the period from 1999 to 2003, using stochastic distant functions. This methodology allows measuring the levels of technical efficiency of the different companies. The results indicates that...

This paper develops a generalized hedonic model in which an exogenous shock to a single product attribute can affect other attributes, the markets for the product's complements and substitutes, and aggregate quantity produced. These factors are shown to be empirically relevant and to cause bias...

Studies employing micro price data suggest that price dispersion is larger between regions in different countries than between regions in the same country. To investigate the strength of this border effect, deviations from the law of one price are used in most studies to provide statistical...

Due to Federal regulations, automobile air bag availability was a model-specific discontinuous function of model year for used vehicles in the 1990s and early 2000s. We use these discontinuities and the gradual increase in the supply of air bags to trace out the demand curve for air bags and the...

Currently there is a significant discussion in academia and the popular press over the present amount of inequality, the history of inequality and the negative effects on economies of inequality. Typical of this debate was a recent article by Martin Wolf in the Financial Times, (30 Sept 2014,...

We show that a minimum wage can have large effects throughout the earnings distribution,using a combination of theory and empirical evidence. To this end, we develop an equilibriumsearch model featuring empirically relevant worker and firm heterogeneity. We usethe estimated model to evaluate a...
