Abstract Background: Recent scientific research explains corporate social responsibility as an economic activity. This paper interprets a means of power to increase firms’ market share in duopoly. Objectives: analyses the duopoly model which firms decide on optimal investments and production two phases. The basic question is how significance conflict affects investments, shares, quantities, pro...

Based on the model of symmetric and asymmetric duopoly option game, this paper discusses the present value of profit flows and the sunk investment costs for the trapezoidal fuzzy number. It constructs the fuzzy expressions of the investment value and investment threshold of followers and leaders under fuzzy environment and conducts numerical analysis. This offers a kind of explanation to the in...

We revisit Fujiwara’s (2008) di¤erential duopoly game to show that the degenerate nonlinear feedback identi…ed by the tangency point with the stationary state line is indeed unstable, given the dynamics of the natural resource exploited by …rms. To do so, we fully characterise the continuum of nonlinear feedback solution via Rowat’s (2007) method, characterising the in…nitely many stable nonlin...

How can a rational player strategically control a myopic best reply player in a repeated two-player game? We show that in games with strategic substitutes or strategic complements the optimal control strategy is monotone in the initial action of the opponent, in time periods, and in the discount rate. As an interesting example outside this class of games we present a repeated “textbook-like” Co...

Bargaining is a basic game in economic practice. Cournot duopoly game is an important model in bargaining theory and is well studied in the literatures. Recently, asymmetry information [20] and incomplete information [19], limited individual rationality [2] and slightly altruistic equilibrium [10] are introduced into bargaining theory. And computational game theory also comes into being a new h...

This paper provides a new explanation of why price reductions take place on a regular basis. It is argued that the demand for a ...rm’s product drops over time because of the erosion of consumers’ brand recall, which in turn can be boosted by price cuts. After analyzing the dynamic optimal choice of price discounts in both monopoly and duopoly settings, I show that a monopolist’s optimal pricin...

We introduce and analyze a multi-period, finite horizon, no-replenishment, dynamic pricing model under duopoly competition between two retailers who sell an identical good. According to our duopoly competition model, a single consumer, whose valuation is uniformly distributed on [0,1], visits only one of the two retailers in each period. If the price posted by the retailer visited by the consum...

We consider the static and dynamic models of Cournot duopoly with tax evasion. In the dynamic model we introduce the time delay and we analyze the local stability of the stationary state. There is a critical value of the delay when the Hopf bifurcation occurs. Mathematics Subject Classification: 34K18, 47N10; Jel Classification: C61, C62, H26
