We simulate the performances of a standard derivatives portfolio to evaluate the relevance of benchmarking in terms of downside risk reduction. The simulation shows that benchmarking always leads to significantly more severe losses in average than those generated by letting the portfolio reach...

The aim of this paper is to study the oil price adjustment dynamics and to implicitly test the efficiency hypothesis for the oil market. Thus, we propose to study the oil price evolution in a nonlinear framework while testing the interdependence hypothesis between oil and stock markets. Four...

We argue that the use of rational expectations in monopolistic markets, as typically done, is overly restrictive because the rationale of this approach is not met in those markets. In a model that encompasses a general equilibrium framework, we consider a monopolist (a producer) with subjective...

We analyze how a benevolent, privately informed government agency would optimally release information about the economy's growth rate when the agents hold heterogeneous beliefs. We model two types of agent: "conforming" and "dissenting." The former has a prior that is identical to that of the...

We analyze how a benevolent, privately-informed government agency would optimally release information about the economy's growth rate when the agents hold heterogeneous beliefs. We model two types of agents: "trusting" and "distrustful." The former has a prior that is identical to that of the...

We observe many episodes in which a large number of people attempt to withdraw their deposits from a bank, forcing it to suspend withdrawals or even to fail. In contrast with the view that those episodes are driven by consumers panic or sunspots, we propose to explain them as a consequence of...
