Modellierung der Abhängigkeiten zwischen Ausfall, Verlustrate und Forderungshöhe bei Ausfall mit Faktoren und Copulae -- Multivariate Erweiterung des Heckman-Schätzers, um der Stichprobenselektion seitens der Verlustrate und der Forderungshöhe gerecht zu werden -- Empirische Befunde zur...

The finance literature looks at a number of factors to explain risk premia in corporate debt, such as liquidity effects, jump-to-default risk, and contagion risk. Stochastic recovery rates as a source of systematic risk have not received much attention so far, most likely due to the difficulties...

The rational-choice framework for modeling matching markets has been tremendously useful in guiding the design of school-assignment systems. Despite this success, a large body of work documents deviations from the predictions of this framework that appear influenced by behavioral-economic...

Forecasters predicting how people change their behavior in response to a treatment or intervention often consider a set of alternatives. In contrast, those who are treated are typically exposed to only one of the treatment alternatives. For example, managers selecting a wage schedule consider a...

Surveys are an essential approach for eliciting otherwise invisible factors such as perceptions, knowledge and beliefs, attitudes, and reasoning. These factors are critical determinants of social, economic, and political outcomes. Surveys are not merely a research tool. They are also not only a...

We measure individual-level loss aversion using three incentivized, representative surveys of the U.S. population (combined N=3,000). We find that around 50% of the U.S. population is loss tolerant, with many participants accepting negative-expected-value gambles. This is counter to earlier...

When solving discrete-time consumption models with present-biased time preferences, backwards induction generates equilibria that are non-robust in the sense that policy functions are often sensitive to parameter choices, including the modeler's choice of the time-step. The current paper...

Using data from a field experiment on exercise, we analyze the relationship between imperfect memory and people's awareness of their limited self-control. We find that people overestimate past gym attendance, and that larger overestimation of past attendance is associated with (i) more...
