Contagious bovine pleuropneumonia (CBPP) is one of the most important infectious diseases of cattle in Africa. Naïve herds can experience losses up to 80%, and many cattle that survive remain chronic carriers. These carriers may suffer from recurrent low-grade fever, loss of condition, and respiratory signs upon exercise, and might introduce the causative agent into uninfected herds. Although c...

When an individual believes that peers are predominantly untruthful in a given situation, is he/she more likely to be untruthful in that situation? We study this question in deception experiments patterned after Gneezy (2005) and conducted in Arizona, California, and India. We find evidence that dishonesty is indeed contagious.

When is a person with a cold contagious? A couple of friends, who are put off when I keep my distance from their sneezing and coughing, insist one is only contagious a week or so before symptoms appear. In the back of my memory is the idea that one remains contagious until a few days *after* primary symptoms disappear. I'm not usually so concerned about this, but I'm coping with a couple of oth...

Is Crime Contagious? Understanding whether criminal behavior is “contagious” is important for law enforcement and for policies that affect how people are sorted across social settings. We test the hypothesis that criminal behavior is contagious by using data from the Moving to Opportunity (MTO) randomized housing-mobility experiment to examine the extent to which lower localarea crime rates dec...

The initial draft of this document was prepared in June 1993 by the Ad hoc Group on Contagious Bovine Pleuropneumonia Surveillance Systems of the Office International des Epizooties. That draft was then amended in February 1997 by the Group of experts convened at the request of the International Committee to examine issues relating to the surveillance of the disease, with particular reference t...

A microtitration serum agglutination test, based on that used for brucellosis, has been developed to detect antibodies in the sera of horses exposed to the contagious equine metritis (CEM) organism. Two known positive sera were tested 100 times in 15 separate tests. The results were reproducible to within a twofold range. The test is capable of being carried out within 100 min.

We study the development of a social norm of trust and reciprocity via the contagious strategy as de ned in Kandori (1992) among a group of strangers. The players anonymously and randomly meet each other and play a binary trust game in the in nite horizon. In order to provide the investors with proper incentives to follow the contagious strategy, the su cient condition requires that there exist...

Humans favor others seen as similar to themselves (ingroup) over people seen as different (outgroup), even without explicitly stated bias. Ingroup-outgroup bias extends to involuntary responses, such as empathy for pain. However, empathy biases have not been tested in our close primate relatives. Contagious yawning has been theoretically and empirically linked to empathy. If empathy underlies c...
