Prisoner's Dilemma

Two people might not cooperate even if it is in both their best interests to do so. The prisoner's dilemma is a standard example of a game analyzed in game theory that shows why two completely "rational" individuals might not cooperate, even if it appears that it is in their best interests to do so. It was originally framed by Merrill Flood and Melvin Dresher working at RAND in 1950. Albert W. Tucker formalized the game with prison sentence rewards and named it, "prisoner's dilemma" (Poundstone, 1992), presenting it as follows:

Productivity Paradox (Solow Computer Paradox)
Worker productivity may go down, despite technological improvements.
| S - | Ep - | |
| - min | ||
The productivity paradox was analyzed and popularized in a widely cited article by Erik Brynjolfsson, which noted the apparent contradiction between the remarkable advances in computer power and the relatively slow growth of productivity at the level of the whole economy, individual firms and many specific applications. The concept is sometimes referred to as the Solow computer paradox in reference to Robert Solow's 1987 quip, "You can see the computer age everywhere but in the productivity statistics." The paradox has been defined as the discrepancy between measures of investment in information technology and measures of output at the national level. It was widely believed that office automation was boosting labor productivity (or total factor productivity). However, the growth accounts didn't seem to confirm the idea. From the early 1970s to the early 1990s there was a massive slow-down in growth as the machines were becoming ubiquitous. (Other variables in country's economies were changing simultaneously; growth accounting separates out the improvement in production output using the same capital and labour resources as input by calculating growth in total factor productivity, AKA the "Solow residual".) The productivity paradox has attracted a lot of attention because technology seems no longer to be able to create the kind of productivity gains that occurred until the early 1970s. Some, such as economist Robert J. Gordon, are now arguing that technology in general is subject to diminishing returns in its ability to increase economic growth.
Proebsting's Paradox
It is counterintuitive that you bet more when some of the bet is at unfavorable odds.

In probability theory, Proebsting's paradox is an argument that appears to show that the Kelly criterion can lead to ruin. Although it can be resolved mathematically, it raises some interesting issues about the practical application of Kelly, especially in investing. It was named and first discussed by Edward O. Thorp in 2008. The Kelly criterion is an often optimal strategy for maximizing profit in the long run. Proebsting's paradox apparently shows that the Kelly criterion can lead to ruin. It is counterintuitive that you bet more when some of the bet is at unfavorable odds.
