According to the environmental Kuznets curve hypothesis, the relationship between per-capita GDP and per-capita pollutant emissions has an inverted-U shape. This implies that, past a certain point, economic growth may actually be profitable for environmental quality. Most studies on this subject...

Nous utilisons un modèle LSTVAR (Logistic Smooth transition Vector Auto Regression) pour questionner la présence d’une relation asymétrique entre la variation du prix du pétrole et les rendements de l’indice SP 500. Les tests statistiques nous ont confortés dans l’utilisation du...

Capital markets may be an important tool in the reduction of pollution emissions. Indeed, they provide firms with an incentive to maintain a good environmental record (or at least, a good reputation) in order to maximize the value of their equity shares. Also, efficient capital markets may...

A Monte Carlo investigation shows that the rejection probability of the structural stability test of Andrews (2003) depends on several characteristics of the DGP, one of which is the length of the hypothesized break period. This is analyzed and found to be caused, at least in part, by the fact...

This paper studies the finite sample performance of the sieve bootstrap augmented Dickey-Fuller (ADF) unit root test. It is well known that this test's accuracy in terms of rejection probability under the null depends greatly on the underlying DGP. Through extensive simulations, we find that it...

Augmented Dickey-Fuller unit root tests may severely overreject when the DGP is a general linear process. The use of the AR sieve bootstrap, proposed by Park (2002) and Chang and Park (2003), may alleviate this problem. We propose sieve bootstraps based on MA and ARMA approximations. Invariance...

We study the problems of bias correction in the estimation of low order ARMA(p, q) time series models. We introduce a new method to estimate the bias of the parameters of ARMA(p, q) process based on the analytical form of the GLS transformation matrix of Galbraith and Zinde-Walsh (1992). We show...

In this article we show that the Gini coefficient is simultaneously decomposable both by sources of income and by populations of income receivers for non-overlapping income distributions: the so-called first-best Gini multi-decomposition. We show that this multidimensional decomposition is...
