We consider a model with an finite number of states of nature where short sells are allowed.

We consider a model with an inffnite number of states of nature, von Neumann - Morgenstern utilities, where agents have different probabil- ity beliefs and where short sells are allowed. We show that no-arbitrage conditions, deffned for ffnite dimensional asset markets models, are not sufficient...

This article reconsiders the theory of existence of efficient allocations and equilibria when consumption sets are unbounded below under the assumption that agents have incomplete preferences. It is motivated by an example in the theory of assets with short-selling where there is risk and...

The euro area is experiencing a sovereign debt crisis; as a result, the foundations of its monetary union have been shattered. This crisis, which is an extension of an international financial crisis, shows that the European Union is not an optimum currency area. Robert Mundell’s work remains...

This article investigates the dynamics of regional financial integration and its determinants in an international setting. We test a conditional version of the international capital asset pricing model (ICAPM) accounting for the deviations from purchasing power parity (PPP) as well as temporal...

The aim of this article is to examine: how the dynamics of correlations between five emerging countries (Argentina, Chili, Hungary, Russia and Poland), two emerging regions (Latin America (LAC) and Europe (EU)) and U.S. evolved from January 2004 to September 2011. The main contribution of this...

We empirically reinvestigate the issue of excess comovement of commodity prices initially raised in Pindyck and Rotemberg (1990) and show that excess comovement, when it exists, can be related to hedging pressure and speculative intensity in commodity futures markets. Excess comovement appears...

This paper evaluates the predictability of WTI light sweet crude oil futures by us- ing the variance risk premium, i.e. the difference between model-free measures of implied and realized volatilities. Additional regressors known for their ability to ex- plain crude oil futures prices are also...

This paper investigates price transmissions across European energy forward markets at distinct maturities during both normal times and extreme ?uctuation periods. To this end, we rely on the traditional Granger causality test (in mean) and its multivariate extension in tail distribution...
