A recurrent problem in economic studies based on survey data is to determine whether survey weights should be used or not. We show that weighted estimators are more robust than unweighted ones, but less accurate when unweighted estimators are consistent. In some circumstances, a compatibility...

The main purpose of this paper is to determine the macro-prudential indicators of financial strength that can be used under supervision of the banking system in CEMAC. More specifically, we start from a set of indicators listed in the literature on macro-prudential supervision, and identify...

In this study, we identifie a small number of indicators of macro-prudential supervision important to monitoring of the banking’s system. We use the theory of Markov stochastic processes to measure the systemic risk of CEMAC by calculating the degree of fragility of system and we determine the...

We study the relationships between the real effective exchange rate (REER) of the Tunisian dinar and its determinants/fundamentals, i.e. the ratio of trade balance/GDP, the ratio of public consumption/GDP, the openness rate and the terms of trade. We find that in the most of cases, the variables...

This manuscript provides an introduction to statistics and probability method. It is structured around three themes developed in five chapters. The first part is an introduction to probability calculations in which we introduce the notions of elementary probability, probabilized spaces, random...

In this paper, we use identification-robust methods to assess the empirical adequacy of a New Keynesian Phillips Curve (NKPC) equation. We focus on the Gali and Gertler's (1999) specification, on both U.S. and Canadian data. Two variants of the model are studied: one based on a...

The Moroccan unemployment figures tell a tale of a statistical misery that hides another one's but more real and painful. First, the purpose of this essay is to highlight the fact that these figures are a product of preemptive arbitrations, in terms of definition and calculation methodology,...
