This paper assesses the importance of nonlinearity in estimating the wealth effects on consumption for the US, the UK and the Euro area. We look at the impact of both (i) aggregate wealth and (ii) disaggregate wealth, namely, by comparing financial wealth effects with housing wealth effects. We...

This paper studies the speculative efficiency of the aluminum contract traded in the London Metal Exchange over the last three decades. We investigate both short and long-run efficiency using linear and nonlinear cointegration approaches and Error Correction Models (ECM). Our findings point out...

This article studies the financial integration between the six main Latin American markets and the US market in a nonlinear framework. Using the threshold cointegration techniques of Hansen and Seo (2002), we show significant threshold stock market linkages between Mexico, Chile and the US....

This paper aims to modeling stock prices adjustment dynamics toward their fundamentals. We used the class of Switching Transition Error Correction Models (STECM) and we showed that stock prices deviations toward fundamentals could be characterized by nonlinear adjustment process with mean...

In this article, we investigate the hypothesis of efficiency of central bank intervention policies within the current global financial crisis. We firstly discuss the major existing interventions of central banks around the world to improve liquidity, restore investor confidence and avoid a...

We investigate the synchronization and nonlinear adjustment dynamics of short-term interest rates for France, the UK and the US using the bi-directional feedback measures proposed by Geweke (1982) and appropriate smooth transition error-correction models (STECM). We find strong evidence of...

This article investigates the evolution of the US risk premium in periods of crisis. First, we estimate a conditional CAPM with time-varying systematic risk and price of risk using a multivariate GARCH-in-Mean model. Second, we study the structural breaks in the US risk premium. Finally, we...

In this paper, we show the usefulness of the switching transition error correction model in reproducing the bilateral linkages between oil and stock markets over the last three decades. Our findings show that while linear models fail to apprehend significant relationships between oil and stock...
