More than half of German adults are overweight. Those most often affected include the elderly, poor, and individuals with poor education. Yet is overweight an issue that economists should address? Poor nutrition and lack of exercise play a major role in widespread diseases. One third of total health care expenditures are devoted to illnesses related to overweight. This is just one of the reasons why ...
Findings from consumer surveys and studies about nutritional labeling tend to be hard to compare, because the methodologies they use and questions they address are quite varied. Nevertheless, by evaluating these studies, we can obtain a good overview of existing nutritional labeling systems and consumer preferences. The present background article offers an overview of the studies frequently cited in ...
This paper investigates the short-term effects of public smoking bans on individual smoking behavior. In 2007 and 2008, state-level smoking bans were gradually introduced in all of Germany's federal states. We exploit this variation to identify the effect that smoke-free policies had on individuals' smoking propensity and smoking intensity. Using rich longitudinal data from the German Socio-Economic ...
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...
We study the literature on school financial education programs for children and youth via aquantitative meta-analysis of 37 (quasi-) experiments. We find that financial education treatmenthas, on average, a significant and sizeable impact on financial knowledge (+0.25 SD), similar toeducational interventions in other domains. Additionally, we document small but still significanteffects on financial ...
We conduct a randomized field experiment to study the effects of two financial education interventions offered to small-scale retailers in Western Uganda. The treatments contrast “active learning” with “traditional lecturing” within standardized lesson-plans. We find that active learning has a positive and economically meaningful impact on savings and investment outcomes, in contrast to insignificant ...
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...
In this study, we set up a DSGE model with upward looking consumption comparison and show that consumption externalities are an important driver of consumer credit dynamics. Our model economy is populated by two different household types. Investors, who hold the economy’s capital stock, own the firms and supply credit, and workers, who supply labor and demand credit to finance consumption. Furthermore, ...
