This paper provides a new way to identify conditional cooperationin a real-time version of the standard voluntary contribution mechanism. Ourapproach avoids most drawbacks of the traditional procedures because it relieson endogenous cycle lengths, which are defined by the number of contributors...

The serial dependency of multivariate nancial data will often be ltered by con-sidering the residuals of univariate GARCH models adapted to every single series.This is the correct ltering strategy if the multivariate process follows a so-calledcopula based multivariate dynamic model (CMD). These...

In this note we present a simple method to include the no-arbitrage condition into thederivation of conditional densities using the principle of maximum entropy. For the case ofidentically and independently distributed returns, we easily derive that the whole processestimated that way is...

We introduce a generalized theoretical approach to study imitation andsubject it to rigorous experimental testing. In our theoretical analysiswe …nd that the different predictions of previous imitation models aredue to different informational assumptions, not to different behavioralrules. It is...
