Moral Impossibility in the Petersburg Paradox : A Literature Survey and Experimental Evidence

The Petersburg paradox has led to much thought for three centuries. This paper describes the paradox, discusses its resolutions advanced in the literature while alluding to the historical context, and presents experimental data. In particular, Bernoulli’s search for the level of moral impossibility in the Petersburg problem is stressed; beyond this level small probabilities are considered too unlikely to be relevant for judgment and decision making. In the experiment, the level of moral impossibility is elicited through variations of the gamble-length in the Petersburg gamble. Bernoulli’s conjecture that people neglect small probability events is supported by a statistical power analysis.

Equity and Efficiency in Multi-Worker Firms: Insights from Experimental Economics

In this paper, we discuss recent evidence from economic experiments that study the impact of social preferences on workplace behavior. We focus on situations in which a single employer interacts with multiple employees. Traditionally, equity and efficiency have been seen as opposing aims in such work environments: individual pay-for-performance schemes maximize efficiency but might lead to inequitable outcomes. We present findings from laboratory experiments that show under which circumstances partially incomplete contracts can create equitable work environments while at the same time reaching surprisingly efficient outcomes.

Size Matters – When it Comes to Lies

A small lie appears trivial but it obviously violates moral commandments. We analyze whether the preference for others’ truth telling is absolute or depends on the size of a lie. In a laboratory experiment we compare punishment for different sizes of lies controlling for the resulting economic harm. We find that people are sensitive to the size of a lie and that this behavioural pattern is driven by honest people. People who lie themselves punish softly in any context.

Asymmetric obligations

We use a laboratory experiment to investigate the behavioral effects of obligations that are not backed by binding deterrent incentives. To implement such expressive law’ we introduce different levels of very weakly incentivized, symmetric and asymmetric minimum contribution levels (obligations) in a repeated public goods experiment. The results provide evidence for a weak expressive function of law: while the initial impact of high obligations on behavior is strong, it decreases over time. Asymmetric obligations are as effective as symmetric ones. Our results are compatible with the argument that expressive law affects behavior by attaching an emotional cost of disobeying the own obligation. —

The impact of the termination rule on cooperation in a prisoner’s dilemma experiment

Cooperation in prisoner’s dilemma games can usually be sustained only if the game has an infinite horizon. We analyze to what extent the theoretically crucial distinction of finite vs. infinite-horizon games is reflected in the outcomes of a prisoner’s dilemma experiment. We compare three different experimental termination rules in four treatments: a known finite end, an unknown end, and two variants with a random termination rule (with a high and with a low continuation probability, where cooperation can occur in a subgame-perfect equilibrium only with the high probability). We find that the termination rules do not significantly affect average cooperation rates. Specifically, employing a random termination rule does not cause significantly more cooperation compared to a known finite horizon, and the continuation probability does not significantly affect average cooperation rates either. However, the termination rules may influence cooperation over time and end-game behavior. Further, the (expected) length of the game significantly increases cooperation rates. The results suggest that subjects may need at least some learning opportunities (like repetitions of the supergame) before significant backward induction arguments in finitely repeated game have force. —

Higher Order Risk Attitudes, Demographics, and Financial Decisions

We conduct an experiment to study the prevalence of the higher order risk attitudes of prudence and temperance, in a large demographically representative sample, as well as in a sample of undergraduate students. Participants make pairwise choices between lotteries of the form proposed by Eeckhoudt and Schlesinger (2006). The choices in these lotteries isolate prudent from imprudent, and temperate from intemperate, behavior. We relate individuals’ risk aversion, prudence, and temperance levels to demographics and financial decisions. We observe that the majority of individuals’ decisions are consistent with risk aversion, prudence, and temperance, in both the student and the demographically representative sample. An individual’s level of prudence is predictive of his wealth, saving, and borrowing behavior outside of the experiment, while temperance predicts the riskiness of portfolio choices. Our findings suggest that the coefficient of relative prudence for a representative individual is approximately equal to two.

Economic and Intrinsic Motivations for Dishonesty: An Experimental Study

We study the role of economic versus intrinsic motivations for dishonesty in two different experimental tasks. In the theft task, participants have the opportunity to steal real physical money, by taking more than they have actually earned in the task. In the reporting task, we use a production task with self-reporting of accidents to study the fraudulent provision of information by individuals. Reporting was compulsory for some participants, but only voluntary for others. We find the incidence of dishonesty varies significantly across both the tasks and the type of reporting, demonstrating that intrinsic motivations can often override economic incentives.

Pigs in Cyberspace: A Natural Experiment Testing Differences between Online and Offline Club-Pig Auctions

We find sale prices and net revenues received by sellers in the Midwestern club pig market are higher at traditional face-to-face auctions than at comparable Internet auctions. The comparison overcomes adverse selection issues that commonly plague such analyses by using data from sellers that allocated pigs to both markets based solely on exogenous differences in dates between online and offline auctions. Furthermore, both auctions feature ascending price formats with âsoft-endingsâ and remaining quality variation is controlled by using detailed information on animal, seller and event characteristics. The results suggest that the higher prices and net revenues from traditional auctions are attributable to remaining differences in auction format and buyer pools. Furthermore, sellers may be willing to forgo higher revenues to capture the convenience and flexibility provided by Internet auctions, to reach buyers in other regions that face different seasonality in demand and to stimulate demand for privately negotiated sales.
