This paper investigates the determinants of stock returns in the French stock market in an Arbitrage Pricing Theory framework. The analysis is conducted with monthly data from the French stock market over the period 1990-2001. Financial theory predicts that a set of macroeconomic variables...

In this article, we extend the conditional ICAPM of De Santis and Gérard (1997,1998) using an asymmetric multivariate GARCH specification. This approach, with double asymmetric effects, allows to the risk premia, betas and correlations to vary through time. Then, we investigate ex ante benefits...

It is proved that the irrelevance result of Poyago-Theotoky can be extended from the linear-quadratic case to general inverse demand and cost functions. Hence, as long as firms are profitable at the first-best, the optimal subsidy decentralizes it in mixed oligopoly irrespecitve of whether the...

White (1996), Poyago-Theotoky (2001) and Myles (2002) prove that in the mixed oligopoly the optimal subsidy, equilibrium output level, all firms' profits and social welfare are identical irrespective of whether the public firm maximizes welfare or profit and moves simultaneously with private...
