The author presents a simple technique for teaching the Cournot model to first-year students. The approach involves demonstrating to the students that out of all rectangles with a common perimeter, the square has the greatest area. No use is made of derivatives. The same approach can be used to...

The concept of ‘fully permissible sets ’ is defined by an algorithm that eliminate strategy subset . It is characterized as choice sets when there is common certain belief of the event that each player prefer one strategy to another if and only if the former weakly dominate the latter on the...

A government that regularly procures the services of construction companies wants to minimize its costs. The instrument it can use is the level of information feedback given to the firms in the market. Theoretically, the competition between firms is supposed to drive prices to the lowest...

We examine the impact of social rewards in an unemployment insurance context. A social norm requires effort in proportion to perceived talent, but individuals cunningly choose effort so as to manipulate the perception of their talent. The model predicts that low talented individuals increase...

The classical price competition model (named after Bertrand), prescribes that in equilibrium prices are equal to marginal costs. Moreover, prices do not depend on the number of competitors. Since this outcome is not in line with real-life observations, it is known as the "Bertrand Paradox". Many...

We extend the consistency principle for strategic games (Peleg and Tijs (1996)) to apply to solutions which assign to each game a collection of product sets of strategies. Such solutions turn out to satisfy desirable properties that solutions assigning to each game a collection of strategy...
