Composition of Electricity Generation Portfolios, Pivotal Dynamics and Market Prices

Author(s) : Banal Estañol, Albert , Rupérez-Micola, Augusto
Description : We use a simulation model to study how the diversification of electricity generation portfolios influences wholesale prices. We find that technological diversification generally leads to lower market prices but that the relationship is mediated by the supply to demand ratio. In each demand case ther...

The Pricing of Academic Journals: A Two-Sided Market Perspective

Author(s) : Jeon, Doh-Shin , Rochet, Jean-Charles
Description : More and more academic journals adopt an open-access policy, by which articles are accessible free of charge, while publication costs are recovered through author fees. We study the efficient pricing of an academic journal from a two-sided market perspective and the consequences of the open access p...

The Provision on Non-audit Services by Auditors: Let the Market Evolve and Decide

Author(s) : Arruñada, Benito
Description : The provision of non-audit services by auditors to their audit clients reduces total costs, increases technical competence and motivates more intense competition. Furthermore, these services do not necessarily damage auditor independence nor the quality of non-audit services. This assessment leads t...

Organized vs. Competitive Corruption

Author(s) : Celentani, Marco , Ganuza Fernández, Juan José
Description : We study bureaucratic corruption in a model in which a constituency sets required levels for a given set of activities. Each activity is carried out by an external provider, and its realization is supervised by a bureaucrat. While bureaucrats are supposed to act on behalf of the constituency, they c...

Almost Sure Testability of Classes of Densities

Author(s) : Devroye, Luc , Lugosi, Gábor
Description : Let a class $\F$ of densities be given. We draw an i.i.d.\ sample from a density $f$ which may or may not be in $\F$. After every $n$, one must make a guess whether $f \in \F$ or not. A class is almost surely testable if there exists such a testing sequence such that for any $f$, we make finitely ma...

Location Models for Airline Hubs Behaving as M/D/c Queues

Author(s) : Marianov, Vladimir , Serra de la Figuera, Daniel
Description : Models are presented for the optimal location of hubs in airline networks, that take into consideration the congestion effects. Hubs, which are the most congested airports, are modeled as M/D/c queuing systems, that is, Poisson arrivals, deterministic service time, and {\em c} servers. A formula is ...

A Zero-delay Sequential Scheme for Lossy Coding of Individual Sequences

Author(s) : Linder, Tamás , Lugosi, Gábor
Description : We consider adaptive sequential lossy coding of bounded individual sequences when the performance is measured by the sequentially accumulated mean squared distortion. The encoder and the decoder are connected via a noiseless channel of capacity $R$ and both are assumed to have zero delay. No probabi...

The Variability of Money Velocity in a Generalized Cash-in-Advance Model

Author(s) : Rodríguez Mendizábal, Hugo
Description : This paper presents a general equilibrium model of money demand where the velocity of money changes in response to endogenous fluctuations in the interest rate. The parameter space can be divided into two subsets: one where velocity is constant and equal to one as in cash- in-advance models, and ano...

A Model of Market-Making

Author(s) : Vriend, Nicolaas J.
Description : The two essential features of a decentralized economy taken into account are, first, that individual agents need some information about other agents in order to meet potential trading partners, which requires some communication or interaction between these agents, and second, that in general agents ...

Multinationals, Technology Networks and International Takeovers

Author(s) : Oliva i Armengol, Maria-Angels , Rivera-Batiz, Luis
Description : We formulate a knowlegde--based model of direct investment through mergers and acquisitions. M&As are realized to create comparative advantages by exploiting international synergies and appropriating local technology spillovers requiring geographical proximity, but can also represent a strategic res...
