The Framing of Games and the Psychology of Play

Psychological game theory can help provide a rational choice explanation of framing effects; frames influence beliefs, beliefs influence motivations. We explain this theoretically, and explore the empirical relevance experimentally. In a 2×2 design of one-shot public good games we show that frames affect subject’s first- and second-order beliefs, and contributions. From a psychological game-theoretic framework we derive two mutually compatible hypotheses about guilt aversion and reciprocity under which contributions are related to second- and first-order beliefs, respectively. Our results are consistent with either.Framing, psychological games, guilt aversion, reciprocity, public good games, voluntary cooperation

The Impact of Fairness on Decision Making - An Analysis of Different Video Experiments

Experimentally observed deviations of behavior from game theoretic predictions suggest that fairness does influence decision making. Fairness in the sense of equality has become an essential element of economic models aiming at explaining actual behavior (cf. Fehr and Schmidt, 1999; Bolton and Ockenfels, 2000). In this paper I will argue that equality is not the only fairness norm to be taken into account. More equity norms than equality exist, including inequality of payoffs. Since inequitable payoff allocations are advantageous for the one player and disadvantageous for the other, subjects may fall prey to a self-serving bias in their fairness perceptions. Opponents may adhere to different conceptions of fairness making agreement impossible. Using the video method (Hennig-Schmidt, 1999) I further show in a bargaining experiment that behavior is goal-oriented. Fairness criteria based on equity norms guide the formation and adaptation of aspiration levels.experimental economics, video experiments, fairness, equity principle, self-serving bias, aspiration levels, decision making

Neutral versus Loaded Instructions in a Bribery Experiment

This paper contributes to the ongoing methodological debate on context-free versus in-context presentation of experimental tasks. We report an experiment using the paradigm of a bribery experiment. In one condition, the task is presented in a typical bribery context, the other one uses abstract wording. Though the underlying context is heavily loaded with negative ethical preconceptions, we do not find significant differences. We conjecture that the experimental design transmits the essential features of a bribery situation already with neutral framing, such that the presentation does not add substantially to subjects' interpretation of the task.Corruption, context, framing, valence, experimental instructions, laboratory, trust, reciprocity, ethical behaviour, social norms

In Search of Workers' Real Effort Reciprocity - A Field and a Laboratory Experiment

We present a field experiment to assess the effect of own and peer wage variations on actual work effort of employees with hourly wages. Work effort neither reacts to an increase of the own wage, nor to a positive or negative peer comparison. This result seems at odds with numerous laboratory experiments that show a clear own wage sensitivity on effort. In an additional real-effort laboratory experiment we show that explicit cost and surplus information that enables to exactly calculate employer’s surplus from the work contract is a crucial pre-requisite for a positive wage-effort relation. This demonstrates that employee’s reciprocity requires a clear assessment of the surplus at stake

Biosynthetic pathway of mitochondrial ATPase subunit 9 in Neurospora crassa

Subunit 9 of mitochondrial ATPase (Su9) is synthesized in reticulocyte lysates programmed with Neurospora poly A-RNA, and in a Neurospora cell free system as a precursor with a higher apparent molecular weight than the mature protein (Mr 16,400 vs. 10,500). The RNA which directs the synthesis of Su9 precursor is associated with free polysomes. The precursor occurs as a high molecular weight aggregate in the postribosomal supernatant of reticulocyte lysates. Transfer in vitro of the precursor into isolated mitochondria is demonstrated. This process includes the correct proteolytic cleavage of the precursor to the mature form. After transfer, the protein acquires the following properties of the assembled subunit: it is resistant to added protease, it is soluble in chloroform/methanol, and it can be immunoprecipitated with antibodies to F1-ATPase. The precursor to Su9 is also detected in intact cells after pulse labeling. Processing in vivo takes place posttranslationally. It is inhibited by the uncoupler carbonylcyanide m- chlorophenylhydrazone (CCCP). A hypothetical mechanism is discussed for the intracellular transfer of Su9. It entails synthesis on free polysomes, release of the precursor into the cytosol, recognition by a receptor on the mitochondrial surface, and transfer into the inner mitochondrial membrane, which is accompanied by proteolytic cleavage and which depends on an electrical potential across the inner mitochondrial membrane

Transport of the precursor to neurospora ATPase subunit 9 into yeast mitochondria

Isolated yeast mitochondria were able to take up Neurospora ATPase subunit 9 in vitro although the homologous yeast protein is synthesized within the mitochondria and inserted into the membrane from the matrix side (Tzagoloff, A., and Meagher, P. (1972) J. Biol. Chem. 247, 594- 603). The transfer of the protein was dependent on an energized mitochondrial inner membrane. It was accompanied by proteolytic processing of the precursor to the mature protein with the correct NH2 terminus as determined by Edman degradation of the transferred protein. The possibility is discussed that there are common features in the uptake machinery neither specific for one species nor specific for individual precursor proteins in the same species

Experimenting over a Long Distance - A method to facilitate intercultural experiments

We report a new method for Experimenting over a Long Distance (ELD)allowing to simultaneously run decentralized interactive experiments in geographically separated subject pools. Applying ELD to an intercultural trust experiment with participants from Argentina, China and Germany we found a striking evidence for transcontinental trust behavior. In addition to Chinese senders’ discrimination of Argentinean players no discrimination in trust and reciprocity behavior was observed. Neverthe- less, we found significantly different levels of trust and reciprocity in the different national cultures.interactive intercultural experiments, investment game, trust
