We discuss statistical inference problems associated with identification and testability in econometrics, and we emphasize the common nature of the two issues. After reviewing the relevant statistical notions, we consider in turn inference in nonparametric models and recent developments on...

This paper puts forward an extended model of cumulative growth in which the effects of education and catch-up are integrated, following the Kaldorian ideas of increasing returns of scale and endogenous technical progress. Based on recent theoretical developments, this model allows for examining...

This article describes the application to an operational medium-size econometric model, mini-DMS, of methods associating, to deterministic forecasts, a measure of the uncertainty due to the stochastic nature of behavioural equations. After having described the theoretical and practical...

The debate on the issue of land rights and its impact on investment and agricultural productivity still divides economic experts and agricultural statistics. While some agree that the link is positive, the effects are often difficult to measure, it is sometimes not only due to the difficulty of...

This paper analyze the causality between copper production , public debt and poverty in D.R. Congo. The model shows that among the factors that are the basis of the welfare deterioration, there is the external debt which is a major obstacle to the fight against poverty.

The recent financial crisis raised awareness of the need for a framework for conducting macroprudential policy. Identifying as early as possible and addressing the buildup of endogenous imbalances, exogenous shocks, and contagion from financial markets, market infrastructures, and financial...

This paper aim to study the impact of teacher status on the behaviour of Benin’s primary school teachers in the context of the growing expansion of the hiring of non civil servant teachers. To address this issue we estimate both negative binomial model and linear instrumental variable model to...

This paper make an overview of the copula theory from a practical side. We consider different methods of copula estimation and different Goodness-of-Fit tests for model selection. In the GoF section we apply Kolmogorov-Smirnov and Cramer-von-Mises type tests and calculate power of these tests...

The objective of this paper is to provide a complete framework to aggregate different quantile and expectile models for obtaining more diversified Value-at-Risk and Expected Shortfall measures, by applying the diversification principle to model risk. Following Taylor (2008) and Gouriéroux and...
