Business surveys aim at getting, as quickly and as simply as possible, the recent and probable changes in economic activity. Answers to most of the questions are qualitative with three modalities (qualification of an evolution: up / stable / down). The qualitative indicators provided by these...

The author describes results obtained by using a new methodology to estimate potential output for the United Kingdom. The estimation method, which follows Rennison (2003) and Gosselin and Lalonde (2002), shows that combining the use of a Hodrick-Prescott filter and a structural vector...

The main objective of this paper is to evaluate technologically (innovation or imitation) the role of human capital in Cameroon as far as economic growth is concerned. Higher education is designed to be the main technological aspect of human capital. Theoretically, the stock of knowledge...

In this paper, we study the asymptotic distribution of a simple two-stage (Hannan-Rissanen-type) linear estimator for stationary invertible vector autoregressive moving average (VARMA) models in the echelon form representation. General conditions for consistency and asymptotic normality are...

We propose methods for testing hypothesis of non-causality at various horizons, as defined in Dufour and Renault (1998, Econometrica). We study in detail the case of VAR models and we propose linear methods based on running vector autoregressions at different horizons. While the hypotheses...

Summary: The European Union absorbs nearly 75% of Tunisian exports and represents about 50% of Tunisian imports, which explains the important weight of the euro in the Tunisian dinar anchor basket. Thus, the purpose of this article is to predict short-term exchange rate fluctuations EUR/TND,...

In this paper, we estimate and analyse a set of equations of French inflation for forecasting purpose at the horizon of three months, six months and one year. A different equation is associated to each horizon. This approach has the advantage of modeling directly the variable of interest at the...
