The Existence and Persistence of the Pay-Per-Use Bias in Car Sharing Services
Author:
Abstract:
A key benefit of using car sharing services (relative to car ownership) is that they are more cost effective. Car sharing firms offer a menu of pricing plans to make this happen. The two most common plans are flat-rate and pay-per-use pricing. However, little is known about how consumers choose among these pricing plans. In this study, we analyze consumers’ choices between pay-per-use and flat-rate pricing using data from a car sharing provider in a large European city. We show that over 40% of customers make nonoptimal pricing plan choices (i.e., they do not choose the cost minimizing plan). In contrast to previous research, we find a prevalent and time-persistent pay-per-use bias; i.e., we find little evidence that consumers “learn”. We propose three potential explanations for the existence and persistence of this bias. First, we suggest that customers underestimate their usage. Second, we propose that customers have a preference for flexibility, leading them to pay more. Finally, we show that the physical context, such as weather, increases the likelihood of a pay-per-use bias. We suggest that the pay-per-use bias may be the prevalent tariff choice bias in the Sharing Economy.

Procrastination and Learning about Self-Control
Author:
Abstract:
We study a model of task completion with the opportunity to learn about own self-control problems over time. While the agent is initially uncertain about her future self-control, in each period she can choose to learn about it by paying a non-negative learning cost and spending one period. If the agent has time-consistent preferences, she always chooses to learn whenever the learning is beneficial. If the agent has time-inconsistent preferences, however, she may procrastinate such a learning opportunity. Further, if her time preferences exhibit inter-temporal conflicts between future selves (e.g., hyperbolic discounting), the procrastination of learning can occur even when the learning cost is zero. The procrastination also leads to a non-completion of the task. When the agent has multiple initially-uncertain attributes (e.g., own future self-control and own ability for the task), the agent’s endogenous learning decisions may be misdirected — she chooses to learn what she should not learn from her initial perspective, and she chooses not to learn what she should.

Deutschland: ein Land der Mieter? Die Rolle von Erwartungen über zukünftige Immobilienpreisentwicklungen
Author:
Abstract:
Mehr als die Hälfte aller Haushalte in Deutschland wohnen zur Miete – ein im internationalen Vergleich sehr hoher Wert. Bisherige Studien haben vor allen Dingen den regulatorischen Rahmen des Immobilienmarkts hervorgehoben, der Mietwohnungen in Deutschland systematisch begünstigt. Allerdings gibt es keine Studien, die diese Erklärungen empirisch eindeutig untermauern können: einige Arbeiten betonen die Bedeutung von fundamentalen Marktdaten wie die Einkommensentwicklung, demographische Faktoren oder den Zuzug in eine Region. Diese Studie greift einen Aspekt auf, der bislang nicht in der Literatur diskutiert wurde. Untersucht wird, ob und zu welchem Anteil die geringe Eigentümerquote in Deutschland durch pessimistische Erwartungen bezüglich zukünftiger Immobilienpreisentwicklungen erklärt werden kann – erwarten Mieter keine oder nur geringe Preissteigerungen, so sinkt die Attraktivität einer Investition in die eigenen vier Wände. Für die empirische Analyse werden Daten aus einer neuen, repräsentativen Befragung, erhoben im Rahmen des SOEP-IS, ausgewertet. Befragte ausländischer Herkunft sind optimistischer hinsichtlich der Immobilienpreisentwicklung. Sie erwarten langfristig einen signifikant höheren Preisanstieg. Dies legt nahe, dass die erheblich pessimistischeren Preiserwartungen der einheimischen Bevölkerung auch dazu führen, dass sie sich seltener als die Bevölkerung in anderen Ländern für selbstgenutztes Wohneigentum entscheiden.

Complexity and Distributive Fairness Interact in Affecting Compliance Behavior
Author:
Abstract:
Filing income tax returns or insurance claims often requires that individuals comply with complex rules to meet their obligations. We present evidence from a laboratory tax experiment suggesting that the effects of complexity on compliance are intrinsically linked to distributive fairness. We find that compliance remains largely una ffected by complexity when income taxes are distributed to a morally justi fied charity. Conversely, complexity signi ficantly amplifi es non-compliance when income taxes appear wasted as they are distributed to a morally dubious charity. Our data further suggest that this non-compliance pattern is facilitated through the ambiguity that evolves from mostly unstrategic fi ling mistakes.

Optimal Social Assistance and Unemployment Insurance in a Life-Cycle Model of Family Labor Supply and Savings
Author:
Abstract:
We empirically analyze the optimal mix and optimal generosity of unemployment insurance and social assistance programs. To do so, we specify a structural life-cycle model of the labor supply, savings, and social assistance claiming decisions of singles and married couples. Partial insurance against wage and employment shocks is provided by social programs, savings, and the labor supplies of all adult household members. We show that the optimal policy mix is dominated by moderately generous social assistance, which guarantees a permanent universal minimum household income, with only a minor role for temporary earnings-related unemployment insurance. The optimal amount of social assistance is heavily influenced by income pooling in married households. This pooling provides partial insurance against negative economic shocks, reducing the optimal generosity of social assistance.

Insurance, Redistribution, and the Inequality of Lifetime Income
Author:
Abstract:
Individuals vary considerably in how much they earn during their lifetimes. We study how the tax-and-transfer system o sets inequalities in lifetime earnings, which would otherwise translate into di erences in living standards. Based on a life-cycle model, we fi nd that redistribution by taxes and transfers off sets 54% of the inequality in lifetime earnings that is due to heterogeneous skill endowments. Meanwhile, taxes and transfers insure 45% of lifetime earnings risk. Taxes would provide more insurance if based on lifetime instead of annual earnings. Requiring wealthy individuals to repay social assistance received when younger would strengthen the insurance and redistributive functions of social assistance.

Financial Education in Schools: A Meta-Analysis of Experimental Studies
Author:
Abstract:
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 (+0.07 SD). When restricting the sample to 18 randomized experiments average effect sizes are estimated to be about 0.15 SD units on financial knowledge and 0.07 SD units on financial behaviors. These results are robust irrespective of the meta-analytic method used and when accounting for publication bias. Subgroup analyses show the beneficial effect of more intensive treatments, albeit with decreasing marginal returns.

Financial Literacy and Intra-Household Decision Making: Evidence from Rwanda
Author:
Abstract:
Research has consistently shown that women’s involvement in household decision making positively affects household outcomes such as nutrition and education of children. Is financial literacy a determinant for women to participate in intra-household decision making? Using data on savings groups in Rwanda, we examine this relationship and show that women with higher financial literacy are more involved in financial and expenditure decisions. Instrumental Variable estimations confirm a causal link. For this reason, we perform a decomposition analysis breaking down the gender gap in financial literacy into differences based on observed sociodemographic and psychological characteristics and differences in returns on these characteristics. Our results show high explanatory power by education, happiness, symptoms of depression, and openness, but also suggest that a substantial fraction can be explained by differences in returns. We argue that this results from a strong role of society and culture.

Coupled Lotteries - A New Method to Analyze Inequality Aversion
Author:
Abstract:
We develop and implement a new measure for inequality aversion: two peers are endowed with identical binary lotteries and the only choice they make is whether they want to play out the lotteries independently or with perfect positive correlation (coupling). Coupling has no other e ect than preventing outcome inequality. We implement the method in a survey in rural Thailand as well as a supplemental sample in a lab in Germany. As theoretically expected, coupling is related to being more risk averse, to having social status concerns, and to relying more often on formal and informal insurance. However, coupling is not related to giving in the dictator game.

The Wage Penalty of Regional Accents
Author:
Abstract:
Previous work has documented that speaking one’s native language with an accent distinct from the mainstream is associated with lower wages. In this study, we seek to estimate the causal effect of speaking with a distinctive regional accent, disentangling the effect of the accent from that of omitted variables. We collected data on workers’ speech in Germany, a country with wide variation in regional dialects. We use a variety of strategies in estimation, including an instrumental variables strategy in which the instruments are based on research findings from the linguistics of accent acquisition. All of our estimators show that speaking with a distinctive regional accent reduces wages by an amount that is comparable to the gender wage gap. We also find that workers with distinctive regional accents tend to sort away from occupations that demand high levels of face-to-face contact, consistent with various occupational sorting models.
