The neural basis of following advice

Biele, Guido; Rieskamp, Jörg; Krugel, Lea K.; … - 2011

Learning by following explicit advice is fundamental for human cultural evolution, yet the neurobiology of adaptive social learning is largely unknown. Here, we used simulations to analyze the adaptive value of social learning mechanisms, computational modeling of behavioral data to describe...

Das hybride Wahlmodell und seine Anwendung im Marketing

Dannewald, Till (contributor); Kreis, Henning (contributor); … - 2007

Traditional choice models assume that observable behavior results from an unspecified evaluation process of the observed individual. When it comes to the revelation of this process mere choice models rapidly meet their boundaries, as psychological factors (e.g., consumers' perception or...

Nonparametric risk management with generalized hyperbolic distributions

Chen, Ying (contributor); Härdle, Wolfgang (contributor); … - 2005

In this paper we propose the GHADA risk management model that is based on the generalized hyperbolic (GH) distribution and on a nonparametric adaptive methodology. Compared to the normal distribution, the GH distribution possesses semi-heavy tails and represents the financial risk factors more...

Competitive risk sharing contracts with one-sided commitment

Uhlig, Harald (contributor); Krueger, Dirk (contributor) - 2005

This paper analyzes dynamic equilibrium risk sharing contracts between profit-maximizing intermediaries and a large pool of ex-ante identical agents that face idiosyncratic income uncertainty that makes them heterogeneous ex-post. In any given period, after having observed her income, the agent...
