We consider distributional free inference to test for positive quadrant dependence, i.e. for the probability that two variables are simultaneously small (or) large being at least as great as it would be were they dependent. Tests for its generalisation in higher dimensions, namely positive...

In this note we propose a general testing procedure for parametric models based on Bartlett Identities. A well-know example is the Information Matrix test, which is based on the Bartlett Identity of order 1. The Identities are shown to induce a sequence of testable restrictions on the data...

We study the impact of graduating in a recession in Flanders (Belgium), i.e. in a rigid labor market. In the presence of a high minimum wage, a typical recession hardly influences the hourly wage of low educated men, but reduces working time and earnings by about 4.5% up to twelve years after...

In recent years there is evidence in the literature that various time series like GNP or production may be nonlinear. In this paper the question is examined whether there are non-linearities in the net production index for the producing sector of the FRG. Three different non-linearity tests are...

Cet article présente une étude empirique relative aux dynamiques non-linéaires sur données à haute fréquence. Les séries de cotation utilisées sont celles du Dollar contre le Mark sur le marché londonien durant l'année 1994. Nous montrons que le caractère leptokurtique et asymétrique...

The non-stationarity of many macroeconomic time-series has lead to an increased demand for economic models that are able to generate fragile equilibria. For instance, the natural unemployment rate is al- lowed to shift over time depending on past unemployment. Actually, many European...

Dans cet article, nous proposons de poursuivre les investigations en matière de parité des pouvoirs d’achat dans le cadre de l’économie chinoise en employant une procédure en deux étapes basée sur des tests de racine unitaire et prenant en compte la présence de points atypiques dans...

The purpose of this paper is to investigate whether shocks to out- put and employment had permanent or transitory effects during the period from 1961 to 1990 in the Federal Republic of Germany. There are a lot of parametric and non-parametric approaches which can be used for data generating...

Le sentier de croissance à taux constant 'endogène' peut être vu comme un nouveau fil du rasoir. Son existence repose sur la stricte égalité à un des rendements d'échelle vis-à-vis des facteurs accumulables. Nous étendons cette constatation en étudiant le sentier de croissance d'une...

This paper considers a special non-linear time series problem, that of testing for co-integration in a Bayesian framework when there is a break in the co-integrating relationship. It is shown that a partial linearization of the likelihood function solves many puzzling questions, in particular...
