This paper analyses the impact of changes in product market competition on the marginal cost of public funds (MCPF) and public goods supply when distortionary commodity taxes are used to raise revenue. First, less competition (measured by a switch from Bertrand to Cournot conduct, or a decrease in the elasticity of demand) does not necessarily raise the MPCF. Second, even if it does, optimal pu...

This study derives pure strategy Bertrand equilibria in a duopoly in which two firms produce a homogeneous good with convex cost functions and seek to maximize the weighted sum of their absolute and relative profits. The study shows that there exists a range of equilibrium prices in duopolistic equilibria. This range of equilibrium prices is narrower and lower than the range of equilibrium pric...

In a theoretical framework we compare production-in-advance type and production-to-order type environments. We carry out our analysis in the framework of a symmetric capacity-constrained Bertrand-Edgeworth duopoly game and prove that the equilibrium profits are the same in case of production in advance and production to order. In addition, advance production results in higher prices than produc...

This paper studies a spatial duopoly model where customers are located at nodes and the demand functions are given for each node. For any fixed location of two firms, we analyze Bertrand-Nash equilibrium and derive a necessary and sufficient condition for the existence of equilibrium. We present an algorithm to compute all equilibria, provided profit functions have a finite number of peaks. The...

Shows equilibrium always exists (Rothschild-Stiglitz-Wilson model) when firms enforce policy exclusivity via strategic (profit-maximizing) communication of client purchases. Strategic communication induces two equilibrium types: partial communication of purchase information or non-communication which exhibits a lemon effect (low-risk purchase no insurance). Nonetheless, Jaynes' configuration (J...

The purpose of our thesis "Strategic Pro…t Sharing Between Firms" is to study the e¤ects of the unilateral and unconditional pro…t sharing strategy on …rms’behavior. The basic model is a two-stage game. In the …rst stage, …rms decide simultaneously what part of their pro…ts to give away to their rival and then, in a second stage, the equilibrium price and quantities are determined. Notice that ...

In a market in which a vertically integrated producer (VIP) supplies an essential input to a retail rival, we explore the role of managerial delegation when it shapes downstream firms’ incentives and determine the endogenous choice of delegation under both Cournot and Bertrand competition. The equilibrium choice of acting as a managerial firm, which is a standard result in literature of strateg...

The thesis studies sellers’ pricing and learning behaviour in Bertrand oligopoly markets using a bounded rational approach. It consists of four chapters. Chapter 1 develops a quantal response adaptive learning model which combines sellers’ bounded rationality with adaptive belief learning in order to explain price dispersion and dynamics in laboratory Bertrand markets with perfect information. ...
