Farsighted game theoretic solution concepts have been shown to provide insightful results in many applications. However, we provide simple examples demonstrating that the existing solution concepts may fail to incorporate some important aspects of farsighted reasoning. This failure stems apparently from the reliance of these concepts on constructs such as indirect dominance which only provide l...
Studies on information sharing in oligopolies focus either Cournot or Bertrand markets. We consider a Cournot–Bertrand market where owners provide strategic managerial incentives and can share the details of their compensation contracts. find that firm punishes its manager for sales, whereas rewards sales. Both firms contract if firms' products are sufficiently differentiated. However, product ...
This paper discusses a model of duopolistic competition in the context of international trade. There are two countries, a home and a foreign country, but consumption happens only in the home country. There are two differentiated (substitute) products, one produced at home and one abroad. Three policies that influence competition in the home country are considered: tariffs, subsidies and quotas....
Nos adentraremos en la obra inspirada poemas de Aloysius Bertrand, compuesta por Maurice Ravel.
For games with discontinuous payoffs Simon and Zame (Econometrica 58:861–872, 1990) introduced payoff indeterminacy, in the form of endogenous sharing rules, which are measurable selections of a certain payoff correspondence. Their main result concerns the existence of a mixed Nash equilibrium and an associated sharing rule. Its proof is based on a discrete approximation scheme “from within” th...
We develop a pricing game modelling a monopoly and an oligopoly of Internet Service Providers selling bandwidth on two complementary segments of a multi-provider communication network. We consider pricing behavior when the oligopolists have previously sold part of their capacity by means of forward contracts, assuming all prices are set simultaneously. We find the equilibria in pure strategies ...
We show that there is a unique correlated equilibrium, identical to the unique Nash equilibrium, in the classic Bertrand oligopoly model with homogenous goods and identical marginal costs. This provides a theoretical underpinning for the socalled “Bertrand paradox” as well as its most general formulation to date. Our proof generalizes to asymmetric marginal costs and arbitrarily many players in...
Introduction: Video games are common cultural issues with great influence in all societies. One of the important cognitive effects of video games is on creating stress on video players. The present research objective was to study different types of stress in players based on video game styles. Methods: A total of 80 players, aged 18 to 30 years, played four types of video games; Ru...
We compare the number of active firms, i.e. the number of firms producing a positive quantity, in equilibrium across four different models of oligopoly: Cournot and Bertrand with homogeneous or differentiated goods. We concentrate on the linear demand structure with constant marginal but asymmetric costs. (With symmetric costs, the results trivialize to all firms active or all firms inactive.) ...
