In this paper we present an axiomatic analysis of several ranking methods for tournaments. We find that two of them exhibit a very good behaviour with respect to the set of properties under consideration. One of them is the maximum likelihood ranking, the most common method in statistics and...

We examine the effect of an oligopolistic upstream electronic market on upstream and downstream prices. The analysis highlights the two sources of competition that a firm that source from an electronic market (e- market firm) face: competition with less efficient firms that source traditionally...

In general equilibrium models with oligopolistic firms, equilibrium outcomes may depend on the choice of numeraire. When firms have the power to influence prices strategically, different price normalisations entail objective profit functions which are generally not monotone transformations of...

This paper examines the justifications, history, and practice of regulation in the US telecommunications sector. We examine the impact of technological and regulatory change on market structure and business strategy. Among others, we discuss the emergence and decline of the telecom bubble, the...

We study dynamic price adjustment under imperfect competition when consumers have non-time-separable preferences. In our model an intertemporal link arises in the consumers' maximization problems because current consumption decisions affect the utility of future consumption. Thus future demand...

This paper analyses oligopolies using the Cournot/Stackelberg framework, but allowing some firms to be pursueing aims other than profit maximisation. The existence of even a single output maximising firm can have dramatic effects on outputs, prices and welfare, even if such a firms faces...

We study the influence of product market competition on the first-price sealed auction and the English ascending auction with independent cost types. Bidders, valuing the license basing on the information released in the first stage license bidding game and the possible game they will play in...
