This paper contains an analysis of stylised natural gas and electricity supply sectors. Power plants operate either on natural gas or on a competing fuel – e.g. oil. The competing fuel is assumed to be traded at world market price whereas natural gas is sold by a national monopoly. The paper...

A substantial number of studies have extended the work on universal properties in physical systems to complex networks in social, biological, and technological systems. In this paper, we present a complex networks perspective on interfirm organizational networks by mapping, analyzing and...

For methods of the profit division in the bilateral monopoly of the mine and the power station sug-gested in the first part of this paper the formulae for lignite price and shares in the joint profit of the mine and the power station are calculated. The proposed profit division contain: the...

We reconsider the problem of cartel stability in a linear symmetric Cournot oligopoly by assuming that every coalition of firms defecting from a cartel can choose its quantity before the remaining firms. We show that differently from Salant et al. (1983) the only profitable cartel includes all...

In order to fight collusive behaviors, the best scenario for competition authorities would be the possibility to analyze detailed information on firms' costs and prices, being the price-cost margin a robust indicator of market power. However, information on firms' costs is rarely available. In...

Estimation of benchmark yield curve in developing markets is often influenced by liquidity concentration. Based on an affine term structure model, we develop a long run liquidity weighted fitting method to address the trading concentration phenomenon arising from horizon-induced clientele...

This paper develops a matching model à la Pissarides (2000) in order to explain the basic facts of housing markets, most of all the variance in house prices. Price dispersion is basically due to both the ex-ante heterogeneity of the parties and the search costs of buyers and sellers. In fact,...

We present an equilibrium search model of competing mechanisms where some buyers are budget constrained. Absent budget constraints, the existing literature capitulates that if buyers differ in their valuations then in the unique equilibrium all sellers hold second price auctions (e.g. McAfee...

We endogenize the trading mechanism selection in a model of directed search with risk averse buyers and show that the unique symmetric equilibrium entails all sellers using fixed price trading. Mechanisms that prescribe the sale price as a function of the realized demand (auctions, bargaining,...

This study attempts to identify some characteristics of the relationship between journalists and politicians. The methodology of the research is based on the analysis of responses to interviews in depth applied to a sample of 50 print and audiovisual journalists from Bucharest, Suceava, Pitesti,...
