The extremal coefficient function has been discussed as an analog of the autocovariance function for extreme values. However, as to the behavior of valid extremal coefficient functions little is known apart from their positive definite type. In particular, the reconstruction of valid processes...

We present a new approach to treatment assignment in (field) experiments for the case of one or multiple treatment groups. This approach - which we call minimizing MSE approach - uses sample characteristics to obtain balanced treatment groups. Compared to other methods, the min MSE procedure is...

This dissertation presents four independent papers that advance experimental methods and test theories on saving using experimentally elicited characteristics. The first two papers test two behavioral theories on precautionary saving based on the characteristics loss aversion and prudence by...

Der Wettbewerb im deutschen Gesundheitswesen ist – vor allem zwischen den Leistungserbringern – trotz diverser Reformen nicht sehr ausgeprägt. Inzwischen gibt es zwar die Möglichkeit, individuelle Verträge zwischen einzelnen Anbietern und den Krankenkassen abzuschließen, dies wird aber...
