Titel: Trust among Internet Traders: A Behavioral Economics Approach
Autor: Gary E. Bolton / Elena Katok / Axel Ockenfels
Abstract: Standard economic theory does not capture trust among anonymous Internet traders. But when traders are allowed to have social preferences, uncertainty about a seller's morals opens the door for trust, reward, exploitation and reputation building. We report experiments suggesting that sellers' intrinsic motivations to be trustworthy are not sufficient to sustain trade when not complemented by a feedback system. We demonstrate that it is the interaction of social preferences and cleverly designed reputation mechanisms that solves to a large extent the trust problem on Internet market platforms. However, economic theory and social preference models tend to underestimate the difficulties of promoting trust in anonymous online trading communities.
Titel: The Supply Side of Organ Allocation
Autor: Axel Ockenfels / Joachim Weimann
Abstract: The benefits of a large organ pool accrue not only to the actual organ recipients themselves, but to others as well due to the insurance it provides against having to wait 'too long' for an organ transplant. We argue that this public good character of a large organ pool makes it economically and ethically justifiable to design a market mechanism that boosts the number of donors. Most importantly, such a mechanism has the potential to substantially alleviate the troubling equity and efficiency problems on the demand side while, at the same time, being entirely independent of the allocation algorithm used for the distribution of organs.

In spite of a missing central authority, without formal controls and sanctions, with anonymity and easy-to-use exit options there is not only chaos and anomy on the Internet. Rath...
