This study examines the effect of a soft commitment device in the form of a savings goal calendar on savings for small business owners in Kampala, Uganda. We run a randomized controlled trial (RCT) under which the treatment group receives a calendar designed to set savings goals and to make a plan to reach this goal. The control group is given a plain calendar. We find no average effect on savings, ...

Most policy instruments to reduce greenhouse gas (GHG) emissions have focused on producers, and on the energy efficiency of buildings, vehicles and other products. Behavioural changes related to climate change also impact ‘in-use’ emissions, and potentially, emissions both ‘upstream’ (including from imported goods) and ‘downstream’ (eg disposal). Consumption-oriented policies may provide avenues to ...

We study the rapidly growing literature on the causal effects of financial education programs in a meta-analysis of 76 randomized experiments with a total sample size of over 160,000 individuals. The evidence shows that financial education programs have, on average, positive causal treatment effects on financial knowledge and downstream financial behaviors. Treatment effects are economically meaningful ...

This paper studies the effects of labor market outcomes on firms’ loan demand and on credit intermediation. In a first step, I investigate how wages in the production sector affect bank net worth and the process of financial intermediation in partial equilibrium. Second, the role of the identified channels are studied in general equilibrium using a new- Keynesian DSGE-model with financial frictions and ...

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 sozialen ...

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.

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 relevance. ...

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 ...

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: 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...
