We prove that there exist equilibrium payoffs arbitrarily close to the efficient payoff in the two-player prisoner’s dilemma with low discounting under imperfect private monitoring, provided that the monitoring structure is not too uninformative, and signals satisfy a condition of positive correlation. We assume no communication, and no public randomization device.

A striking aspect of human coordination is that we achieve it with little or no communication. We achieve this implicit coordination by taking the perspective of others and inferring their intentions. In contrast, robots usually coordinate explicitly through the extensive communication of utilities or intentions. In this paper we present a method that combines both approaches: implicit coordina...

The stress-buffering model posits that social support mitigates the relation between negative life events and onset of depression, but prospective studies have provided little support for this assertion. The authors sought to provide a more sensitive test of this model by addressing certain methodological and statistical limitations of past studies with prospective data from 496 adolescent girl...

Zusammenfassung: Das multimedia lecture board (mlb) ist ein sogenanntes Shared Whiteboard und ermöglicht die Präsentation und die gemeinsame Bearbeitung von Dokumenten in computergestützten Videokonferenzen. Es wurde im Rahmen des DFN-Projekts “ANETTE” speziell für den Einsatz in TeleteachingVeranstaltungen entwickelt und findet seit dem Sommersemester 2001 Verwendung an verschiedenen Universit...

Classified broadly, two motives for intra-family transfers exist: altruism and selfishness. This paper examines two selfish hypotheses − the exchange motive (strategic bequest motive) and the demonstration effect − using a new Japanese micro data set. My analysis of the determinants of intergenerational co-residence, distance between residences, and frequency of contact yields considerable supp...

We tested the hypothesis that stimulus-related contextual information that is incidental to task demands-an episodic code-is automatically, obligatorily encoded and stored as a part of short-term memory (STM) representations. Four experiments employed a running span task to investigate the effects of manipulating two types of contextual information: stimulus grouping and color. Three experiment...

The concept of working memory emphasizes the interrelationship between the transient retention of information and concurrent processing activity. Three experiments address this relationship in children between 8 and 17 years of age by examining forgetting when a processing task is interpolated between presentation and recall of the memory items. Unlike previous studies, delivery of interpolated...

In considering the expected social loss of the jury process, we investigate the role of peremptory challenges based on observable juror characteristics such as race or gender. The effectiveness of peremptory challenges depends on the relative social costs of incorrect verdicts and hung juries, and on jury pool population demographics. Some of our results are: (a) for a defendant clearly in the ...

When children witness or experience criminal events, the first people they go to are generally parents. Typically, no one else is privy to these conversations, and consequently little is known about their specific content. Research has shown that children can be quite accurate witnesses at times. However, they can also incorporate information from misleading and suggestive questions into their ...
