Abstract
This paper illustrates how audio-visual data from pre-play face-to-face communication can be used to identify groups which contain free-riders in a public goods experiment. It focuses on two channels over which face-to-face communication influences contributions to a public good. Firstly, the contents of the face-to-face communication are investigated by categorising specific strategic information and using simple meta-data. Secondly, a machine-learning approach to analyse facial expressions of the subjects during their communications is implemented. These approaches constitute the first of their kind, analysing content and facial expressions in face-to-face communication aiming to predict the behaviour of the subjects in a public goods game. The analysis shows that verbally mentioning to fully contribute to the public good until the very end and communicating through facial clues reduce the commonly observed end-game behaviour. The length of the face-to-face communication quantified in number of words is further a good measure to predict cooperation behaviour towards the end of the game. The obtained findings provide first insights how a priori available information can be utilised to predict free-riding behaviour in public goods games.

Expectation Formation, Financial Frictions, and Forecasting Performance of Dynamic Stochastic General Equilibrium Models

Special Issue: Governing by Numbers
2019
Abstract
In this paper, we document the forecasting performance of estimated basic dynamic stochastic general equilibrium (DSGE) models and compare this to extended versions which consider alternative expectation formation assumptions and financial frictions. We also show how standard model features, such as price and wage rigidities, contribute to forecasting performance. It turns out that neither alternative expectation formation behaviour nor financial frictions can systematically increase the forecasting performance of basic DSGE models. Financial frictions improve forecasts only during periods of financial crises. However, traditional price and wage rigidities systematically help to increase the forecasting performance.

Fairness pays off
When companies arbitrarily cut their wages, the motivation and productivity of the employees decrease – this is clear. Less obvious, however: employees also become less productive even if it is their colleagues who are treated unfairly and not them. This was confirmed by a research group led by Sabrina Jeworrek at the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association.

Indirekte Effekte von als unfair wahrgenommenem Arbeitgeberverhalten auf die Produktivität von Beschäftigten
Sabrina Jeworrek
Wirtschaft im Wandel,
No. 3,
2018
Abstract
Jede Organisation, die darüber nachdenkt zu restrukturieren, Löhne zu kürzen oder Angestellte zu entlassen, sollte auch über mögliche Reaktionen der persönlich nicht betroffenen Arbeitnehmer nachdenken. Dieser Beitrag präsentiert Ergebnisse eines Feldexperiments. Es offenbart, dass die als unfair wahrgenommene Handlung des Arbeitgebers – in diesem Fall die Entlassung von Arbeitskollegen – die anschließende Produktivität der nicht direkt betroffenen Arbeitskräfte mindert. Als Teil des Experiments antizipierten erfahrene Personalmanager zwar im Durchschnitt erfolgreich die Konsequenzen unfairen Arbeitgeberverhaltens auf nicht betroffene Arbeitnehmer, einzeln lagen sie jedoch oft daneben.

What is holding back the banking union?
The European Commission wants to better regulate and monitor the European banking sector. In many EU Member States, however, the necessary directives are being implemented extremely slowly. Surprisingly, the reasons for this do not lie in politics and banking structures, but in the institutional framework conditions and existing regulations in the Member States, as argued by Michael Koetter, Thomas Krause and Lena Tonzer from the Halle Institute for Economic Research (IWH).
