Moral hazard in expert diagnoses is more complicated in credence goods markets because ex-post verification of service optimality is usually not possible. We provide an experimental framework to investigate expert and consumer behavior as well as market efficiency in a setting in which experts...

We analyze how childhood hunger affects human aging for a panel of European individuals. For this purpose, we use six waves of the Survey of Health, Aging, and Retirement in Europe (SHARE) dataset and construct a health deficit index. Results from log-linear regressions suggest that, on average,...

In this paper I propose a time-consistent method of discounting hyperbolically that contains the discount rate implied by Gamma discounting as a special case. I apply the discounting method to three canonical environmental problems: (i) optimal renewable resource use, (ii) the tragedy of the...

We investigate a market in which experts have a moral hazard problem because they need to invest in costly but unobservable effort to identify consumer problems. Experts have either high or low qualification and can invest either high or low effort in their diagnosis. High skilled experts are...

In this paper I unify the economic theories of addiction and health deficit accumulation and develop a life cycle theory in which individuals take into account the fact that the consumption of addictive goods reduces their health and longevity. I distinguish two types of addiction: perfect and...

Markets for credence goods are classified by experts alone being able to identify consumers' problems and determine appropriate services for solution. Examining a market where experts have to invest in costly diagnosis to correctly identify problems and consumers being able to visit multiple...

The current migration and refugee crisis in Europe requires an understanding of the different migration drivers beyond the well-known economic determinants. In this paper, we view migration from a broader human security perspective and analyze the determinants of regular and irregular migration...

Women in Mexico spent at least three times as much time on unpaid work compared to men. It is argued that these duties restrict women in their time use and channel them into flexible working arrangements, which are predominantly in the informal economy. This motivates the hypothesis investigated...

A lot of economic and social situations can be described as contests in which agents need to distribute scare resources. Individual behavior plays an important role within these situations, while identity strongly impacts on behavior. This paper asks how group identity impacts the provision of a...

This paper uses international migration data and climate variables in a multi-country setting to investigate the extent to which international migration can be explained by changes in the local climate and whether this relationship varies between groups of countries. Moreover, the primary focus...
