Résumé

Cet article examine la décision optimale de couverture d'une firme faisant face à un double risque prix-quantité. Dans un cadre d'espérance d'utilité, nous montrons que la notion de prudence au sens de Kimball (1990) est essentielle dans la caractérisation de la position optimale de la firme sur le marché à terme. Plus surprenant, les notions d'aversion au risque et de prudence, peuvent donner lieu à des effets contraires, notamment lorsque la firme souhaite spéculer.

Summary

Summary

This paper studies the optimal hedging policy of a risk-averse firm facing both price and quantity uncertainties. In an expected utility framework, prudence in the Kimball's (1990) sense is shown to play a major role in the characterization of the optimal hedging policy. More surprising is the possibility of conflicting effects between risk aversion and prudence, when the firm wishes to speculate.
