A common observation in experiments involving finite repetition of the prisoners’ dilemma is that players do not always play the single-period dominant strategies (“finking”), but instead achieve some measure of cooperation. Yet finking at each stage is the only Nash equilibrium in the finitely repeated game. We show here how incomplete information about one or both players’ options, motivation...

Homicide-suicides are relatively uncommon and vary from region to region. In the selected literature that we reviewed, shooting was the common method of killing and suicide, and only 3 cases of homicidal ha...

A long-standing issue with centrally committed electricity markets is the design of non-confiscatory and equilibrium-supporting prices. This is because the social planner’s problem in such a market is a non-convex unit commitment. O’Neill et al. (2005) propose a pricing scheme that overcomes these issues for any market that can be formulated as a mixed-integer linear program. Moreover, claims a...

Aboriginal people were victimized by a stranger in 25% of all violent incidents, compared to 45% of incidents committed against...
