We attempt to formulate and explain two types of self-fulfilling prophecy, called the Pygmalion effect (if a supervisor thinks her subordinates will succeed, they are more likely to succeed) and the Galatea effect (if a person thinks he will succeed, he is more likely to succeed). To this...

We anlyze the stochastic control approach to the dynamic maximization of the robust utility of consumption and investment. The robust utility functionals are defined in terms of logarithmic utility and a dynamically consisten convex risk measure. The underlying market is modeled by a diffusion...

This article discusses the limitations of the orthodox economic theory of the firm as a nexus of contracts. Various experimental studies have shown that the aggregation of individuals in groups changes behavior and preferences systematically. This perspective has been formalized by models of...

We give an explicit PDE characterization for the solution of the problem of maximizing the utility of both terminal wealth and intertemporal consumption under model uncertainty. The underlying market model consists of a risky asset, whose volatility and long-term trend are driven by an external...

We reconsider the well known Becker-Coase (BC) argument, according to which changes in divorce laws should not affect divorce rates, in the context of households which consume public goods in addition to private goods. For this result to hold, utility must be transferable both within marriage...

Most would agree that priority setting is necessary to avoid a financial collapse in the health sector. It is much harder to find criteria how to do it. Discussions lead straight to the principles of decision making. But since all theories depend on assumptions given to make them work, debates...

This paper studies the problem of optimal investment with CRRA (constant, relative risk aversion) preferences, subject to dynamic risk constraints on trading strategies. The market model considered is continuous in time and incomplete; furthermore, financial assets are modeled by Itô processes....

When person A makes an offer to person B and B rejects it, then A may lose face. This loss of face is assumed to occur only if B knows for sure of A's offer. While under some circumstances loss of face can be rationalized by the consequences for future reputation, it may also enter directly into...
