In this paper, we consider a source, which communicates to destination, with cooperation of a relay node. An eavesdropper is tapping the second hop, when all the links undergo Rayleigh fading. Relay nodes are the market players, who compete to trade their power to source in order to maximize their incentives. We evaluate the secrecy outage probability of a dual-hop decode-and-forward (DF) thres...

This paper analyzes the effects of product innovation on the firms’ investment behavior in a dynamic duopoly framework. A differential games setting is considered where initially two firms are active on a homogenous product market. One of the firms has an option to introduce a new product that is horizontally and vertically differentiated from the established product. The resulting differential...

We take a game theory approach to study the make-or-buy decisions of firms in a mixed duopoly. We assume that a managerial firm and a profit-oriented firm compete in a duopoly market for a final good, and they can choose whether making an intermediate input or buying it from a monopolistic upstream firm. We find that different equilibria may arise, depending on parameter constellations. In part...

In this paper, taking the factor of product service provided by manufacturers into consideration, a static Bertrand duopoly game with is studied first, in which these two oligarchs produce differentiated products. A dynamic bounded rationality established using gradient mechanism. Keeping adjustment speeds relatively small range may help long-term stable operation market. It found that there an...

We allow quality variations in a duopoly of locationally differentiated products a-la-Hotelling (1929). We analyze the impact of quality variations on the choices of the varieties produced. We show that in a sequential game of variety choice and subsequent quality and price choice there exist only maximal variety differentiation equilibria in pure strategies. Maximal variety differentiation is ...

Big box retail stores have large impact on local economies and receive large subsidies from local governments. Hence it is important to understand how discount retail chains choose store locations. In this paper, I study the entry decisions of those firms, examine the role of preemptive incentives, and evaluate the impact of government subsidies on those decisions. To quantify preemptive incent...

We build a dynamic duopoly model that accounts for the empirical observation of monopoly persistence in the long run. More specifically, we analyze the conditions under which it is optimal for the market leader in an initially duopoly setup to undertake pre-emptive R&D investment, (“strategic predation” strategy) that eventually leads to exit of the follower firm. The follower is assumed to ben...
