We study food Engel curves among the poor population targeted by a conditional cash transfer programme in Colombia. After controlling for the endogeneity of total expenditure and for the (unobserved) variability of prices across villages, the best fit is provided by a log-linear specification....

We investigate the effects of the drastic tariff reductions of the 1980s and 1990s in Colombia on the wage distribution. We identify three main channels through which the wage distribution was affected: increasing returns to college education, changes in industry wages that hurt sectors with...

In this paper we present empirical evidence of the importance of aggregation bias in Euler equations for consumption. The main result is that estimates of the elasticity of intertemporal substitution for consumption are consistently lower for aggregate data than for average cohort data. In...

How far can shoe-leather go in explaining the welfare cost of inflation? Using a unique set of microeconomic data on households, we estimate the parameters of the demand for money derived from a generalized Baumol-Tobin model. Our data set contains information on average holdings of cash, on...
