Dynamic spectrum sharing is a promising technology to improve spectrum utilization in the future wireless networks. The flexible spectrum management provides new opportunities for licensed primary user and unlicensed secondary users to reallocate the spectrum resource efficiently. In this paper, we present an oligopoly pricing framework for dynamic spectrum allocation in which the primary users...

According to the essential facilities doctrine, competition law requires an infrastructural monopoly to provide access. Under the ”Bronner criterion”, proposed by the EC Court, the doctrine is only applicable when an infrastructural duopoly is non-viable. This paper uses a simple model to illustrate that, from a welfare point-of-view, the Bronner criterion may provide too little monopoly protec...

We consider a quantity-setting duopoly model, and we study the decision to move first or second, by assuming that the firms produce homogeneous goods and that there is some demand uncertainty. The competitive phase consists of two periods, and in either period, the firms can make a production decision that is irreversible. As far as the firms are allowed to choose (non-cooperatively) the period...

A unionized duopoly model to analyse how unions affect the incentives for merger is considered. It is found that both firms will merge if and only if unions are weak. However, once surplus-maximizing unions have the option to delegate the wage bargaining to wage-maximizing delegates (such as senior union members), both firms may have incentives to merge even if the union bargaining power is str...

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 examine a vertically differentiated duopoly where firms invest in process and product innovation and then compete in prices under full market coverage. We show that (i) process and product innovation are complements (substitutes) for the low-quality (high-quality) firm; (ii) the firm which is initially more efficient invests more than the rival in process innovation; (iii) if the initial dif...

In this paper we consider a duopoly two-stage duopoly where firms first decide whether to invest in advertising and then compete in prices. Advertising has two effects: a market enlargement for both firms and a predatory gain for the investing firm only. Both symmetric and asymmetric equilibria may arise. The two most interesting cases are a coordination game where both firms investing and non-...

Often models for understanding the impact of management practices on retail performance are developed under the assumption of stability, equilibrium and linearity, whereas retail operations are considered in reality to be dynamic, non-linear and complex. Alternatively, discrete event and agent-based modelling are approaches that allow the development of simulation models of heterogeneous non-eq...
