In the analysis of tax reform, when equity is traded off against efficiency, the measurement of the latter requires us to know how tax- induced price changes affect quantities supplied and demanded. In this paper, we present various econometric procedures for estimating how taxes affect demand.

This paper proposes a systematic framework for analyzing the dynamic effects of permanent and transitory shocks on a system of "n" economic variables.

Many unit root and cointegration tests require an estimate of the spectral density function at frequency zero at some process. Kernel estimators based on weighted sums of autocovariances constructed using estimated residuals from an AR(1) regression are commonly used. However, it is known that...

We specify and estimate a general health equation. Among the determinants of health, we include employment status, alcohol use, and cigarette use. Non linear instrumental techniques are employed to control for any possible endogeneity of these variables.
