A decision maker (DM) wishes to select a competent candidate to …ll a position.However, since the wage and task of the position is predetermined, the DM cannot usecontract as a screening device. This paper formulates the problem as a class of selectionproblem and derives the optimal selection...

In this paper we develop the rst estimator of the covariance matrix that relies solely onforward-looking information. This estimator only uses price information from a cross-sectionof plain-vanilla options. In an out-of-sample study for US blue-chip stocks we show that aminimum-variance strategy...

A small lie appears trivial but it obviously violates moral commandments. We analyze whetherthe preference for others’ truth telling is absolute or depends on the size of a lie. In a laboratoryexperiment we compare punishment for different sizes of lies controlling for the resultingeconomic...

We consider a simple extension of the basic new-Keynesian setup in which we relaxthe assumption of frictionless financial markets. In our economy, asymmetricinformation and default risk lead banks to optimally charge a lending rate above therisk-free rate. Our contribution is threefold. First,...

This paper shows that, for CEU preferences, the axioms consquentialism, state independenceand conditional certainty equivalent consistency under updating characterise a family of capacities,called Genralised Neo-Additive Capacities (GNAC). This family contains as special casesamong others...

Applying the framework of conditional event studies shows that equity issues reveal managers‟private information about stock mispricing, which investors only partially discount into stockprices at the seasoned equity offering (SEO) announcement date. Negative abnormal returnsoccur as prices...
