Economic Sentiment: Disentangling Private Information from Public Knowledge
IWH Discussion Papers,
This paper addresses a general problem with the use of surveys as source of information about the state of an economy: Answers to surveys are highly dependent on information that is publicly available, while only additional information that is not already publicly known has the potential to improve a professional forecast. We propose a simple procedure to disentangle the private information of agents from knowledge that is already publicly known for surveys that ask for general as well as for private prospects. Our results reveal the potential of our proposed technique for the usage of European Commissions‘ consumer surveys for economic forecasting for Germany.
Erinnerung an soziale Isolation des Lockdowns macht Menschen egoistischer
Wirtschaft im Wandel,
Nachdem Teilnehmer eines Online-Experiments an die soziale Isolierung des Lockdowns erinnert wurden, verhielten sich diese egoistischer als eine neutrale Vergleichsgruppe. Allerdings beurteilten Teilnehmer eines weiteren Experiments, die ebenfalls an die soziale Isolation im Lockdown erinnert wurden, ein solches egoistisches Verhalten als prinzipiell sozial unangemessen. Daraus lässt sich schließen, dass lediglich die Neigung zur Befolgung sozialer Normen, welche menschliches Verhalten in den verschiedensten Lebenssituationen maßgeblich beeinflussen, durch die soziale Distanzierung gesunken ist. Auch für eine Zeit nach der Bewältigung der Corona-Pandemie werfen diese Ergebnisse Fragen auf: Wie lässt sich in einer digitalisierten Welt, in der persönliche Interaktionen immer seltener werden, die Bereitschaft zur Einhaltung sozialer Normen aufrechterhalten?

Communication instead of conflict – why are female CEOs so interesting for hedge funds
The value of female-led firms is enhanced more by the intervention of activist investors than that of firms with male CEOs. This is the result of a recent paper by Iftekhar Hasan (Fordham University and IWH) and Qiang Wu (Rensselaer Polytechnic Institute, RPI) at the Halle Institute for Economic Research (IWH). "The results show that female CEOs particularly benefit from the intervention of hedge fund activists due to their strong communication and interpersonal skills," explains Iftekhar Hasan. This is because, on average, the intervention of an activist hedge fund increases the value of the firm ex post. To achieve this, activist hedge funds such as Carl Icahn, Trian Fundmanagement or Elliott prefer to rely on communication and cooperation with the management.

Alone at Home: The Impact of Social Distancing on Norm-consistent Behavior
IWH Discussion Papers,
Around the globe, the COVID-19 pandemic has turned daily live upside down since social distancing is probably the most effective means of containing the virus until herd immunity is reached. Social norms have been shown to be an important determinant of social distancing behaviors. By conducting two experiments and using the priming method to manipulate social isolation recollections, we study whether social distancing has in turn affected norms of prosociality and norm compliance. The normative expectations of what behaviors others would approve or disapprove in our experimental setting did not change. Looking at actual behavior, however, we find that persistent social distancing indeed caused a decline in prosociality – even after the relaxation of social distancing rules and in times of optimism. At the same time, our results contain some good news since subjects seem still to care for norms and become more prosocial once again after we draw their attention to the empirical norm of how others have previously behaved in a similar situation.
Did GRW Investment Grants Contribute to the Catching-up of East Germany?
Konferenzband "30 Jahre Deutsche Einheit", März
The joint task force ‘Improving Regional Economic Structures’ (GRW) is the most important regional policy scheme in Germany and was extensively used to support the economic transformation process in the new states after reunification. The article provides an overview of national and international causal analytical studies on the effects of investment grants. The analysis shows that such programmes have positive effects on development — especially of employment and income. It not only affects the subsidised establishment benefit from this type of support, but the regions as a whole. Even though the studies do not go back to the early 1990s, we can conclude that the GRW contributed to economic development in East Germany — and to the catching-up process.
