This paper investigates the relationship between private and public investment in R&D, while taking into account the effect of several instruments policies such as subsidies and taxes. We design a new look of knowledge spillovers and R&D cooperation to explain the contribution of public and...

Test for unit root based in wavelets theory is recently defined (Genay and Fan, 2007). While the new test is supposed to be robust to the initial value, we bring out by contrast the significant effects of the initial value in the size and the power. We found also that both the wavelets unit root...

Within a forward forecast test on Dynamic Conditional Correlation (DCC), we investigate the contagion of the subprime financial crisis between American, European and Asian stocks under asymmetry. In order to study this phenomenon we will follow these stages: Firstly we will use the Iterated...

Dans cet article, nous analysons le taux d'intérêt réel pour les bons du Trésor américain à trois mois par l'intermédiaire d'une représentation SETAR (Self Exciting Threshold AutoRegressive). Dans le but de distinguer la non linéarité de la non-stationnarité, nous utilisons des tests...

In order to comply with their commitments under the Kyoto Protocol, France and Germany participate to the European Union Emission Trading Scheme (EU ETS) which concerns predominantly electricity generation sectors. In this paper we seek to know if the EU ETS gives appropriate economic incentives...

Many structural break and regime-switching models have been used with macroeconomic and financial data. In this paper, we develop an extremely flexible modeling approach which can accommodate virtually any of these specifications. We build on earlier work showing the relationship between...

Testing for a unit root in a series obtained by summing a stationary MA(1) process with a parameter close to -1 leads to serious size distortions under the null, on account of the near cancellation of the unit root by the MA component in the driving stationary series. The situation is analysed...

This paper studies the impact of the main external shocks which the eurozone and member states have undergone since the start of the 2000s. Such shocks have been monetary (drop in global interest rates), financial (two stock market crises) and real (rising oil prices and an accumulation of...
