May 2020Social Interactions in Pandemics: Fear, Altruism, and Reciprocity
with Laura Alfaro, Ester Faia, Nora Lamersdorf: w27134
In SIR models, homogeneous or with a network structure, infection rates are assumed to be exogenous. However, individuals adjust their behavior. Using daily data for 89 cities worldwide, we document that mobility falls in response to fear, as approximated by Google search terms. Combining these data with experimentally validated measures of social preferences at the regional level, we find that stringency measures matter less if individuals are more patient and altruistic preference traits, and exhibit less negative reciprocity community traits. We modify the homogeneous SIR and the SIR-network model to include agents' optimizing decisions on social interactions. Susceptible individuals internalize infection risk based on their patience, infected ones do so based on their altruism, and re...
July 2012Target Revaluation after Failed Takeover Attempts – Cash versus Stock
with Ulrike Malmendier, Marcus Matthias Opp: w18211
Cash- and stock-financed takeover bids induce strikingly different target revaluations. We exploit detailed data on unsuccessful takeover bids between 1980 and 2008, and show that targets of cash offers are revalued on average by +15% after deal failure, whereas stock targets return to their pre-announcement levels. The differences in revaluation do not revert over longer horizons. We find no evidence that future takeover activities or operational changes explain these differences. While the targets of failed cash and stock offers are both more likely to be acquired over the following 8 years than matched control firms, there are no differences between cash and stock targets, neither in the timing nor in the value of future offers. Similarly, we cannot detect differential operational polic...
