Wangenheim, Jonas von - 2017

In many trade environments - such as online markets - buyers fully learn their valuation for goods only after contracting. I characterize the buyer-optimal ex-ante information in such environments. Employing a classical sequential screening framework, I find that buyers prefer to remain...

Getting it right : communication, voting, and collective truth finding

Burdea, Valeria; Woon, Jonathan - 2023

and statements, and we investigate whether communication improves information aggregation and the accuracy of group … decisions. Our findings suggest that the effect of communication depends on the underlying accuracy of individual judgments …. Communication improves accuracy when individuals tend to be incorrect, but diminishes it when individuals are likely to be correct …

Finding relevant variables in sparse Bayesian factor models : economic applications and simulation results

Kaufmann, Sylvia; Schumacher, Christian - 2012

This paper considers factor estimation from heterogenous data, where some of the variables are noisy and only weakly informative for the factors. To identify the irrelevant variables, we search for zero rows in the loadings matrix of the factor model. To sharply separate these irrelevant...

Vector autoregression analysis and the great moderation

Benati, Luca (contributor); Surico, Paolo (contributor) - 2007

Most analyses of the U.S. Great Moderation have been based on VAR methods, and have consistently pointed toward good luck as the main explanation for the greater macroeconomic stability of recent years. Using data generated by a New-Keynesian model in which the only source of change is the move...

We present the estimated large-scale three-region DSGE model GEAR picturing Germany, the Euro Area and the Rest of the world. Compared to existing models of this type, GEAR incorporates a comprehensive fiscal block, involuntary unemployment and a complex international structure. We use the model...

On a quest for robustness : about model risk, randomness and discretion in credit risk stress tests

Siemsen, Thomas; Vilsmeier, Johannes - 2018

In this paper we study the impact of model uncertainty, which occurs when linking a stress scenario to default probabilities, on reduced-form credit risk stress testing. This type of uncertainty is omnipresent in most macroeconomic stress testing applications due to short time series for banks'...

Persuasion against self-control problems

Wangenheim, Jonas von - 2018

I derive a social planner's optimal information design in an environment with quasi-hyperbolic discounting consumers without commitment. Consumption induces instantaneous utility, but unknown delayed cost. Consumers may or may not acquire additional costless information on the cost parameter....
