Minority Faculty Hiring Power in Academe: an Economic Model

This paper investigates whether minorities in academe exercise bargaining power in a way that influences hiring of other minority faculty. We develop a stylized model that shows how minorities influence the hiring of other minorities, taking into account the hiring of majority faculty. We postulate that such behavior is similar to the behavior of insider workers in the context of the insider-outsider literature.     

Soccer transfers,team efficiency and the sports cycle in the most valued European soccer leagues – have European soccer teams been efficient in trading players?

The sale of soccer players is a serious issue for the sustainability of professional teams. This article discusses the efficiency of the values that 183 European soccer teams have received for the sales of their players since 2007. We estimated stochastic frontiers for these soccer teams using stochastic frontier analysis. We found that teams with higher numbers of titles, with huge past acquisitions of players, and achieving good rankings in the previous season tend to receive more transfer inflows. The efficiency of these inflows can be significantly influenced if the team exhibits a long sports history or if the team participates in the Champions League or in the Europa League.     

Equilibria in reflexive Banach lattices with a continuum of agents

We consider exchange economies with a measure space of agents and for which the commodity space is a separable and reflexive Banach lattice. Under assumptions imposing uniform bounds on marginal rates of substitution, positive results on core-Walras equivalence were established in Rustichini-Yannelis [27] and Podczeck [25]. In this paper we prove that under similar assumptions on marginal rates of substitution, the set of competitive equilibria (and thus the core) is non-empty.     

The state of Portuguese research in economics: an analysis based on publications in international journals

In this paper I analyze the state of Portuguese research in economics based on publications in international journals for the period of 1986 to 2000. I find that scientific production is increasing but productivity remains low. I also provide a revealing characterization of the production habits of Portuguese researchers by answering the following questions: where do Portuguese researchers publish? who are the most active publishers? how often do they publish? how much do they collaborate? what is their background? Finally, I analyze the impact of that research based on citation counts.Received: July 2001, Accepted: November 2001, Mathematics Subject Classification: A10, A14I would like to acknowledge the helpful comments of the Editor, Paulo Brito, as well as Ana Rute Cardoso, Clara Dismuke, João Santos Silva, Octávio Figueiredo, Pedro Pita Barros and Pedro Portugal.     

From Schumpeterian Democracy to Constitutional Democracy

A critical issue of a constitutional democracy is to determine an optimal limitation of citizens' political liberties. This problem is analysed here within the framework of a parliamentary system of government, and in the context of Rawls' principle of equal political participation. It is argued that optimal barriers to entry into political competition are a function of the legislative decision rules, the domain of collective choices, and the rules for selecting (and dismissing) the executive. Contrary to Schumpeter and Riker who rejected populism (the approach that public policy should be a result of citizens' preferences), we argue that it is possible to reconcile greater citizen participation and liberal democracy with an appropriate institutional design.     

Assessing the economics of auto recycling activities in relation to European Union Directive on end of life vehicles

Technical requirements for car design and minimum reuse and recovery rates for end-of-life vehicles (ELV) are the subject of a new EU Directive on ELV. This Directive is expected to induce changes in the infrastructures required for ELV processing, and presents a challenge to maintain such economically viable infrastructure.Technical-cost models of ELV processing operators were developed to interpret the changing economics of auto recycling activities under the new EU Directive on ELV.The results obtained show that the recycling targets defined in the EU Directive for 2006, require the removal of an increased number of plastic parts from an ELV. In particular, removing up to 14% of the ELV mass results in a recycling rate over 80%, even for vehicles with a ferrous content up to about 65%. These operations can be performed economically by dismantlers, provided that they may get a steady flow of ELV hulks, free of charge, and that the international quotation for steel scrap does not come significantly below 120 €/ton.In the long term, developing separation technologies for automotive shredder residues and finding recycling possibilities for the products gained from the separation, might be a valuable scenario to meet the 2015 recycling quotas.     

Horizontal Mergers,Entry and International Trade

We use a two‐country trade model to analyze an authority's decision to approve or reject a merger followed by entry, when the entrant can choose where to locate. We show that approval of a merger in the small country followed by timely, likely and sufficient entry may lead to lower consumer welfare than its rejection: when the alternative to such entry is entry into another country that also benefits consumers through trade, then the gains of attracting entry are small. In this context, we discuss differences between optimal decisions by the small country's authority, large country's authority and supranational authority.     

TV white spaces exploitation through a bicameral geo-location database

The exploitation of TV white spaces can meet the increasing demand for spectrum resources and create opportunities for deploying a variety of wireless services in a flexible manner. However, uncertainties from technologies, business models and regulatory policies hinder the take-off of TV white spaces exploitation. This paper proposes a bicameral (or two-chambered) geo-location database, which allows/supports both free and paid access to the TV white spaces: i.e., one chamber supports free access through opportunistic or geo-location database access; and the other chamber supports paid usage through secondary spectrum trading. Consequently, four technological scenarios for the acquisition of TV white spaces emerge, namely: sensing only, joint sensing and geo-location database access, geo-location database access only, and broker based secondary spectrum trading. An analysis of these scenarios is performed based on a theoretical framework for emerging technology evaluation while considering technological, business models and regulatory dimensions. The analyses show that free and paid access to TV white space complement each other; and that despite considerable infrastructure costs, the bicameral geo-location database is positioned to create viable TV white spaces exploitation value chains; hence have the most optimal technological, business and regulatory prospects.     

An assessment of the equality of access and no-regulation approaches to next generation networks

The European Commission believes that for the regulation of next generation fixed telecommunications networks the continuity approach is preferable to the equality of access approach and the no-regulation approach. According to the European Commission, (i) functional separation eliminates discrimination and promotes competition, but should only be used as a measure of last resort because it involves various complex trade-offs, whereas (ii) the no-regulation approach fosters investment, at the cost of sacrificing competition. The article agrees that functional separation involves complex trade-offs but disputes the assertion that functional separation necessarily eliminates discrimination and promotes competition. In addition, the article also establishes conditions under which the no-regulation approach does not reduce competition.
