The Effect of Peer Observation on Consumption Choices: Evidence from a Lab-In-Field Experiment

We investigate the impact of peer observation on consumption decisions using a lab-in-field experiment. Respondents make consumption decisions either alone or under peer observation. We find evidence for peer effects. We are able to study these further by looking into the mechanism and performing detailed heterogeneity analysis. Concerning the mechanisms, we find evidence for an information channel. ...

Consumer Rating Dynamics

(joint with André Stenzel and Peter Schmidt) We consider dynamic price-setting in the presence of rating systems and asymmetric information about product quality. We provide a framework in which the price charged determines the characteristics of purchasing consumers. The price has two effects on future ratings: (i) a direct price effect on reviews, and (ii) an indirect selection effect...

Antibiotic Resistance: Socio-Economic Determinants and the Role of Information and Salience in Treatment Choice (ABRSEIST)

Antibiotics have contributed to a tremendous increase in human well-being, saving many millions of lives. However, antibiotics become obsolete the more they are used as selection pressure promotes the development of resistant bacteria. The World Health Organization has proclaimed antibiotic resistance as a major global threat to public health. Today, 700,000 deaths per year are due to...

The Effect of Social Comparison on Debt Taking: Experimental Evidence

A number of studies show that there is a link between social comparison and high levels of household debt. However, the exact mechanisms behind this link are not yet well understood. In this paper, we perform a lab experiment designed to study the eff ects of social image concerns and peer information on consumption choices that can be financed through debt taking. We find that having to announce ...

Systemic Usury and the European Consumer Credit Directive

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 ...

Hours Risk and Wage Risk: Repercussions over the Life-Cycle

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. ...

Mobile Money is Driving Financial Development in Africa

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 ...

Where is the Consumer Center? A Case of St. Petersburg?

In an urban economy, the distribution of people and real estate prices depends on the location of the central business district of a city. As distance from the city center increases, both prices and population density diminish, for travel costs increase in terms of time and money. As manufacturing gradually leaves the cities, the importance of consumer amenities as attractors of population to the urban ...
