Laboratory experiments have generally supported the theorem that, in classical property rights environments, noncooperative behavior in markets yields efficient social outcomes. Experiments, however, regularly fail to support the game theoretic prediction of noncooperative behavior in small-group strategic interaction and in large-group public good environments. In these two types of experiment...

In important situations, individual decision-making is systematically biased. When deciding (rather than consuming), extrinsic attributes of choice options are more salient than intrinsic attributes. People overestimate extrinsic attributes and therefore put too much effort into acquiring income and gaining status, lowering their utility level. These mistakes are accentuated in authoritarian sy...

We examine self-control problems — modeled as time-inconsistent, presentbiased preferences—in a model where a person must do an activity exactly once. We emphasize two distinctions: Do activities involve immediate costs or immediate rewards, and are people sophisticated or naive about future self-control problems? Naive people procrastinate immediate-cost activities and preproperate—do too soon...

2014 The second virial coefficient A2 for a mixture of two monodisperse polymers is studied by means of the renormalization group. It is found that the cross-term A12 has a finite limit if the segment number of one of the polymers tends to infinity. Such behaviour predicts a maximum of A2 in dependence on the relative composition of the polymers. The maximum resulting from our firstorder RG-cal...

In many business transactions, in labor-management relations, in international conflicts, and welfare state reforms bargainers hold strong entitlements that are often generated by claims that are not feasible any more. These entitlements seem to considerably shape negotiation behavior. By using the novel setup of a ‘bargaining with claims’ experiment we provide new systematic evidence tracking ...

In this paper we present an original model of sequential problem choice within scientific communities. Disciplinary knowledge is accumulated in the form of a growing tree-like web of research areas. Knowledge production is sequential since the problems addressed generate new problems that may in turn be handled. This model allows us to study how the reward system in science influences the scien...

A continuous phytochemical study on the roots of Marsdenia tenacissima led to the isolation and identification of 13 new polyoxypregnane glycosides named marstenacissides B10-B17 (1, 2, 4, 7, 8, 11, 12, and 14) and marstenacissides A8-A12 (3, 9, 10, 13, and 15) in addition to two known polyoxypregnane glycosides marsdenosides M and L (5 and 6). Their structures were established by spectroscopic...

We investigate experimentally whether emotions affect bidding behavior in a first price auction. To induce emotions, we confront subjects after a first auction series with a positive or negative random economic shock. We then explore the relation between emotions and bidding behavior in a second auction series. Our main results are: (i) the economic shock has a substantial impact on the experie...
