In this paper we propose a consistent test of the linearity of quantile regression models, similar to the Integrated Conditional Moment (ICM) test of Bierens (1982) and Bierens and Ploberger (1997). This test requires re-estimation of the quantile regression model by minimizing the ICM test...

This paper uses linear and non-linear diffusion index models and combination of them to produce one-step-ahead forecast of quarterly Brazilian GDP growth rate. The non-linear diffusion index models are not only parsimonious ones, but they also purport to describe economic cycles through a...

The objective of this paper is to evaluate the effect of the 1985 “Employment Services for Ex-Offenders†(ESEO) program on recidivism. Initially, the sample has been split randomly in a control group and a treatment group. However, the actual treatment (mainly being job related...

In standard cross-sectional wage regressions, married men appear to earn 10 to 20 percent more than comparable never-married men. One proposed explanation for this male marriage premium is that men may be selected into marriage on the basis of characteristics valued by employers as well as by...

Estimates of neighborhood effects on children's outcomes vary widely among the studies that seek to identify their existence and magnitude, reflecting substantial variation in data and model specification. Here, we review that literature, and ask if the disparity in estimates of neighborhood...

Given observations on a stationary economic vector time series process we show that the best <italic>h</italic>-step ahead forecast (best in the sense of having minimal mean square forecast error) of one of the variables can be consistently estimated by nonparametric regression on an ARMA memory index. Our...
