This econometric study takes a simulation approach to investigate the impact of external debt on economic growth in sub-Saharan African countries using a small macroeconomic model estimated for 1970-1994. An important finding was the significance of debt overhang variables in the investment...

We show that, in many circumstances, the size distortion of a bootstrap P value for a test will be one whole order of magnitude smaller than that of the corresponding asymptotic P value. We also show that, at least in the parametric case, the magnitude of the distorsion will depend on the shape...

A unit root test is usually carried out by using the regression test introduced by Dickey and Fuller (1979). Under the null hypothesis the series should be a random walk and a stationary component. This is what is done in additive decompositions between trend and cycle. The paper analyses the...

Dans la pratique, la plupart des statistiques de test ont une distribution de probabilite de forme inconnue. Generalement, on utilise leur loi asymptotique comme approximation de la vraie loi. Mais, si l'echelon dont on dispose n'est pas de taille suffisante cette approximation peut etre de...

Dans cette note, nous nous proposons de modeliser le comportement d'une grandeur croissante dont l'evolution peut etre representee graphiquement par une courbe en forme de "S" incline. A cet effet, nous envisageons quatre fonctions assez classiques: arctangente, logistique, de Gompertz et de...

After 1984 and following economic liberalisation, income inequality in Mexico has increased. Some of the main factors that have contributed to this trend are the relative expansion of the average income in the service sector in relation to the agricultural and manufacturing sectors, which is...

This paper considers the determinants of a binary indicator for the existence of functional limitations using seven waves (1991-1997) of the British Household Panel Survey(BHPS). The focal point of our analysis is a consideration of the relative contributions of state dependence, heterogeneity...

The study defines a common scheme for study the conditions of a firm, approaches and models for determining optimal decisions. They are developed for firms from the wine production industry. Suggested are versions of development of the wine production. A total structure of the model is given....

Researched and evaluated are the continuity and succession of structural changes. Analysed is the purposed by G. Minassian coefficient of direction of structural dynamics. The latter is brought to a mode which allows for it to be calculated directly from the relative shares of the partitions of...

This paper investigates the asymptotic properties of the ordinary least squares estimator for spatial autoregressive models. We show that this estimator is biased as well as inconsistent for the parameters regardless of the distribution of the error term. Illustrative examples are also provided.
