We propose new data-driven smooth tests for a parametric regression function. The smoothing parameter is selected through a new criterion that favors a large smoothing parameter under the null hypothesis. The resulting test is adaptive rate-optimal and consistent against Pitman local...

Simulation evidence is presented on the finite sample properties of two tests for stationarity recently proposed by Kwiatkowski, Phillips and Schmidt (1991) and Park (1990). Unlike earlier unit-root tests, these test the null of stationarity against the alternative of a unit root, thereby...

Uno de los temas más interesante de la econometría aplicada, es aquel que trata sobre las funciones de producción. En este manual se tratan las formas funcionales CES, Cobb - Douglas, VES y Translog. Se realiza una breve reseña de cada forma funcional y se muestra su especificación...

We report here on the design and first application of an interactive computer-administered personal interview (CAPI) survey eliciting from high school students and college undergraduates their expectations of the income they would earn if they were to complete different levels of schooling. We...

China¡¯s recent accession to the WTO is expected to accelerate its integration into the world economy, which aggravates concerns over the impact of globalization on the already rising inter-region income inequality in China. This paper discusses China¡¯s globalization process and estimates...

We propose to combine recent developments in univariate and mul- tivariate unit root testing in order to construct a more powerful panel unit root test. We extend the GLS-detrending procedure of Elliott, Rothenberg and Stock (1996) to a panel Augmented Dickey-Fuller test. The .nite sample power...

In this paper we investigate the possibility of the application of subsampling procedure for testing cointegration relations in large multivariate systems. The subsampling technique is applied to overcome the difficulty of nonstandard distribution and nuisance parameters in testing for...

Common factors play an important role in many disciplines of social science. In economics, the factors are the common shocks that underlie the co-movements of the large number of economic time series. The question of interest is whether some observable economic variables are in fact the...

In this paper we apply wavelet analysis to the class of fractionally integrated processes to show that this class is a member of the $1/f$ family of processes as defined by Wornell (1993) and to produce an alternative method of estimating the fractional differencing parameter. Currently the...

This paper develops a consistent OLS estimate of a fractionally integrated processes' differencing parameter, using continuous wavelet theory as constructed from smoothing kernels. We show that a log-log linear relationship exists between the variance of the wavelet coefficient and the level at...
