We study employment, employee effort, wages and profit sharing when firms face stochastic revenue shocks and when base wages and profit shares are determined through collective bargaining. The negotiated profit share depends positively on the relative bargaining power of the trade union and has...

Assessing the effects of monetary policy and wage bargaining on employment and inflation in the European Monetary Union (EMU), in the first step a Post-Keynesian competitive claims model of inflation with endogenous money is developed. In this model the NAIRU is considered to be a short-run...

A simple Ising spin model which can describe the mechanism of advertising in a duopoly market is proposed. In contrast to other agent- based models, the influence does not flow inward from the surrounding neighbors to the center site, but spreads outward from the center to the neighbors. The...

In this paper, we analyze how an airline can take advantage of airport dominance of a whole network in a market characterized by short-haul routes and congestion. In order to tackle this issue, we estimate an equation system, which is based on theoretical grounds, for the Spanish domestic...

This paper presents a duopoly model of the securities settlement industry. Because pooling a large amount of payments can help in using liquidity efficiently, issuers prefer systems where a large number of securities are issued. If the central securities depositories establish a mutual link that...

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...
