On the evening of Saturday 11 June 1842, Thomas Arnold, the educational reformer and Headmaster of Rugby school, strolled in the institutional gardens with his head boy, William Charles Lake. Thomas would subsequently dine with the Sixth Form boys; a customary act on the last day of term. His diary entry for that evening noted, ‘‘The day after to-morrow is my birthday, if I am permitted to see ...

This paper shows that the cost as well as the effectiveness of technology has a differential impact on technology adoption under two alternative modes of competition. If the cost of the technology is high, Bertrand competition provides a stronger incentive to adopt technology than Cournot competition unless the effectiveness of the technology is very low. On the contrary, if the cost of the tec...

Recent experiments suggest that games where actions are strategic substitutes rather than strategic complements exhibit some desirable performance characteristics. This paper reports an experiment conducted to test whether these characteristics extend to differentiated product Cournot and Bertrand markets. We find that Cournot markets do not generally outperform Bertrand markets, and that the o...

The Bertrand paradox question is: “Consider a unit-radius circle for which the length of a side of an inscribed equilateral triangle equals 3 . Determine the probability that the length of a ‘random’ chord of a unit-radius circle has length greater than 3 .” Bertrand derived three different ‘correct’ answers, the correctness depending on interpretation of the word, random. Here we employ geomet...

Comparing Cournot and Bertrand Equilibria Revisited by Jim Y. Jin This paper compares Cournot and Bertrand equilibria with mixed products, linear demand and cost functions. It is found that a firm's price (output) need not be higher (lower) in Cournot equilibrium. However, given any number of firms and a mixture of complement and substitute products, every firm's price margin/output ratio is al...

Incentives and Welfare Effect of Sharing Firm-Specific Information by Jim Y. Jin* This paper studies the incentives and the welfare effect of sharing firm-specific information in asymmetric Cournot and Bertrand oligopoly with mixed substitute and complement goods. Revealing firm-specific cost information is the dominant strategy in Cournot oligopoly, while concealing is so in Bertrand oligopoly...

It is a commonplace that in the development of modern logic towards its actual shape at least two directions or traditions have to be distinguished. These traditions may be called, following the model of Ivor Grattan-Guinness (1988 ), the tradition of the algebra of logic and the tradition of mathematical logic. They are represented by the developments going back to the British algebraist Georg...
