Unfortunately the event is cancelled. As soon as a new date is fixed, it will be announced here on the website. The Berlin IO Day is a one-day workshop sponsored by the Berlin Centre for Consumer Policies (BCCP) and supported by the Berlin's leading academic institutions, including DIW Berlin, ESMT Berlin, Humboldt-Universität zu Berlin, and Technische Universität Berlin. The aim is to
Abstract: How exactly do individuals approach financial decisions? Do they apply sophisticated formulas, back of the envelope math, do they guess or something else? We show that literally asking individuals to explain their approaches generates new insights about those questions that are reliable and have predictive power out of sample. We find, for example, that when assessing the
Abstract: Trust is thought to be an important driver of economic growth and other economic outcomes. Previous studies suggest that trust may be a combination of risk attitudes, distributional preferences, betrayal aversion, and beliefs about the probability of being reciprocated. We compare the results of a binary trust game to the results of a series of control treatments that remove the
We study the literature on school financial education programs for children and youth via a quantitative meta-analysis of 37 (quasi-) experiments. We find that financial education treatments have, on average, sizeable impacts on financial knowledge (+0.33 SD), similar to educational interventions in other domains. Additionally, we document smaller effects on financial behaviors among students (+0.
We decompose permanent earnings risk into contributions from hours and wage shocks. To distinguish between hours shocks, modeled as innovations to the marginal disutility of work, and labor supply reactions to wage shocks we formulate a life-cycle model of consumption and labor supply. Both permanent wage and hours shocks are important to explain earnings risk, but wage shocks have greater
There are various reasons why humans may want to reduce their consumption of meat and other animal products. In the following, we lay out important stylized facts about individual meat consumption, and then discuss the challenges and puzzles surrounding effective behavior change toward more sustainable, plant-based diets.
Wucher ist ein häufiges Phänomen auf den Verbraucherkreditmärkten und betrifft insbesondere Haushalte mit niedrigem Einkommen. Obwohl der Begriff Wucher Bilder eines gierigen Individuums beschwört, das bewusst handelt, um die schwache Verhandlungsposition eines anderen mit irreführenden und sogar betrügerischen Mitteln auszunutzen, betrachten wir ihn als systemisches Problem: als ein Problem der U
Abstract: The rise of dominant firms in data driven industries is often credited to their alleged data advantage. Empirical evidence lending support to this conjecture is lacking. In this paper, we show that data as an input into machine learning tasks displays features that favor the hypothesis that data is a source of market power. We study the search result quality for search keywords on
Abstract: In online commerce, obfuscation strategies by sellers are hypothesized to mislead consumers to their detriment and to the profit of sellers. One such obfuscation strategy is partitioned pricing in which the price is split into a base price and add-on fees. While empirical evidence suggests that partitioned pricing impacts consumer decisions through salience effects, its consumer
Abstract: When a patient with symptoms of urinary tract infection arrives at a physician's office, it needs to decide which antibiotic drug to prescribe. A drug's efficacy in treating the infection depends on the individual, time-dependent resistance profile of the bacterium causing the infection. Physicians can conduct antibiotic susceptibility tests in order to create current resistance profiles
