Empirical evidence suggests that both leisure time and medical care are important for maintaining health. We develop a general equilibrium macroeconomic model in which taxation is a key determinant of the composition of these two inputs in the endogenous accumulation of health capital. In our...

Winning admission to an elite school both promises modest rewards and imposes substantial risks on many students. Using variation in school assignment generated by the allocation mechanism, we ï¬nd that admission to a system of elite public high schools in Mexico City raises end-of-high school...

One of the leading methods of estimating the structural parameters of DSGE mod- els is the VAR-based impulse response matching estimator. The existing asymptotic theory for this estimator does not cover situations in which the number of impulse response parameters exceeds the number of VAR model...

I use the Prescott (1975) hotels model to explain variations in price dispersion across goods sold by supermarkets in Chicago. I extend the theory to accounts for the monopoly power of chains and for non-shoppers. The main empirical finding is that the effect of demand uncertainty on price...

One of the leading methods of estimating the structural parameters of DSGE mod- els is the VAR-based impulse response matching estimator. The existing asymptotic theory for this estimator does not cover situations in which the number of impulse response parameters exceeds the number of VAR model...

We provide a new proof of the non-emptiness of approximate cores of games with many players of a finite number of types. Earlier papers in the literature proceed by showing that, for games with many players, equal-treatment cores of their "balanced cover games", which are non-empty, can be...

This article provides an introduction to the use of social welfare functions for the comparative evaluation of social alternatives. Three main approaches are considered: Bergson–Samuelson social welfare functions, Arrovian social welfare functions, and Sen's social welfare functionals....

We argue that nonhomothetic preferences with habit formation in nondurable and durable consumption can be a driving force behind sectoral comovement in production. We make this point by augmenting a two-sector New Keyesian model a la Barsky, House and Kimball (2007) with these two real features...
