An alternative to Wesner's method of detecting deterministic behavior and chaos in small sample sets is presented. This new method is applied to analyze the dynamics of several stock prices.

We propose a bootstrap algorithm for autoregressions based on the approximation of the data generating process by a finite state discrete Markov chain. We discover a close connection of the proposed algorithm with existing bootstrap resampling schemes, run a small Monte-Carlo experiment, and...

Using data from Labor Force Surveys (LFS), this study implements additive models to analyze the impact of schooling on wages. It also uses the Sperlich, Tjostheim and Yang (2002) test to validate the existence of interaction terms. Results confirm that the earnings-schooling relationship...

In this paper an original estimator of long memory is considered. It is based on the scaling function directly extracted from multifractal formalism. Monte Carlo simulations show that the scaling function gives interesting results, notably in terms of confidence intervals, which are smaller than...

Whether good macroeconomic policy facilitates aid effectiveness in generating growth is a highly debated topic. In this paper we investigate if economic reform has a favorable effect on the aid-growth relation—specifically, if reform enhances the effect of aid on growth. In doing so, we...

This paper shows by simulation experiments some failures of the KPSS test when the source of the nonstationarity is explained by an unconditional volatility shift. So, a complementary test is proposed. An application to the US Dollar/Euro exchange rate reveals an instability in the unconditional...

The empirical results through a fixed effects regression model show that the initial level of productivity has a negative effect on the contribution of efficiency to productivity growth, which implies that technological catch-up has done much to cause economic convergence among countries....

This note applies conditional density estimation as a visual method to present results. The proposed method is illustrated by application to a firm-level manufacturing data set from Ecuador in 2002.

Horrace and Oaxaca (2001) treat the regressors in gender wage gap by industry measures as non-stochastic when computing the corresponding standard errors. However, the non-stochastic regressors assumption is thought to be inappropriate in modern econometrics. In this paper, we derive the correct...

In this paper, we consider efficient estimation of coefficients of interest in seemingly unrelated regressions (SUR) models. Using the GMM interpretation of the usual OLS and GLS/FGLS estimation of regression coefficients in SUR models, we derive the necessary and sufficient condition for the...
