This study aims to identify the leading of inflation indicators of monetary policy in DRC. The results reveal that the most relevant inflation indicators usually come from the monetary origin than the real sector. Variance decomposition analyzes place in the foreground the rate of exchange, the money supply and the public consumption like the most relevant indicators. In order to achieve its goal of price stability and to support a strong economic growth, the intermediate objective of the Central Bank baseded on the controle of the money supply seems to be less relevant. Relates to a high level of the dollarization, the central bank will be able to adopt either the strategy of nominal anchoring of the rate of exchange, this calls the return of the fixed exchange regime or to adopt a strategy of inflation targeting is to restore the credibility of the monetary policy
This article is the detailed version of a paper on dark matter, dark energy, and modified gravity, published in the December 2015-January 2016 special issue of La Recherche (in French)
Being aware of the motivation problems observed in many scientific oriented careers, we present two experiences to expose to college students to environments, methodologies and discovery techniques addressing contemporary problems. This experiences a
We introduce a notion of positive pair of contact structures on a 3-manifold which generalizes a previous definition of Eliashberg-Thurston and Mitsumatsu. Such a pair gives rise to a locally integrable plane field $lambda$. We prove that if $lambda$
A new standpoint on financial time series, without the use of any mathematical model and of probabilistic tools, yields not only a rigorous approach of trends and volatility, but also efficient calculations which were already successfully applied in
We present preliminary results from a project aimed at exploring elliptical galaxies in numerical simulations within cosmological context to provide possible formation scenarios for samples of observed galaxies. We studied the integrated properties o
