Mobile money is an innovation that allows financial transactions to be performed via a cell phone. Even in poor regions of Africa, almost everyone has a cell phone; therefore, mobile money could both contribute to the continent’s economic growth and ensure that no Africans are excluded from access to financial services. However, DIW Berlin data from Uganda show that mobile money is actually used less ...

About two billion people in the world do not own a financial account and there are many more who use financial services only occasionally. In the past, initiatives which address these problems of financial exclusion focused on the supply side of financial markets, in particular by increasing the branch network of banks and by offering cheap bank products. While this had the desired effect, recent ...

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 ...

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 ...

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 ...

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 ...

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...
