Scoring rules: A cooperative game-theoretic approach
1999
In this work we define the game of the alternatives for each preference profile, and establish relations between scoring rules and cooperative solution concepts for that game, such as the family of semivalues and the family of least square values.
Most-favored-customer pricing, product variety, and welfare
2013
Abstract Most-favored-customer (MFC) clauses are usually seen as anticompetitive co-ordination devices that firms adopt for the purpose of higher prices. Here, I examine the welfare impact of MFC clauses under endogenous product variety. Product variety is relevant because prospective higher prices from MFC clauses can be anticipated by multi-product firms in their provision of product lines. Under such circumstances, I find that these clauses can be socially harmful, but this is not always the case: they tend to be socially neutral for relatively large fixed costs of product-line assortment, harmful for intermediate costs, and beneficial for relatively small costs.
Income Equality and Income Taxation
1994
In every society the distribution of income plays an essential role — not only for economists but also for social scientists and politicians. Most people agree that the laissez-faire allo-cation is not equitable but that some redistribution using taxes has to take place. Most of the literature has supposed that a Bergson- Samuelson social welfare function is the appropriate tool for capturing social values in such analyses. However, there are some objections against this approach. First, interpersonal comparability of the individual utilities is needed — an extremely strong and questionable claim. Second, most writers have worked with a concave transformation of individual cardinal utilitie…
Welfare, Home Market Effects, and Horizontal Foreign Direct Investment
2005
We investigate the spatial distribution and organization of an imperfectly competitive industry when firms may choose to operate more than a single production unit. Focusing on a short-run setting with a fixed mass of firms, we fully characterize the spatial equilibria analytically. Comparing the equilibrium and the first-best, we show that both organizational and spatial inefficiencies may arise. In particular, when fixed costs are low enough the market outcome may well lead to overinvestment and, therefore, to too many multinationals operating from a social point of view. Furthermore, once multinationals are taken into account, the market outcome may well lead too little agglomeration.
Changes in Transport and Non Transport Costs: Local vs. Global Impacts in a Spatial Network
2007
We develop a multi-country Dixit-Stiglitz trade model and analyze how industry location and welfare respond to changes in: (i) transport frictions (e.g., infrastructure, transportation technology); and (ii) non-transport frictions (e.g., tariffs, standards and regulations). We show that changes in non-transport frictions, which are usually origin-destination specific, do not allow for any clear prediction as to changes in industry location and welfare; whereas changes in transport frictions, which are usually not origin-destination specific, may allow for such predictions. In particular, we show that reductions in transport frictions occurring at links around which the spatial network is lo…
Multistage Dynamics of International Environmental Agreements: Free-riding from Membership and Compliance*
2009
Abstract In dealing with the multistage dynamics of international environmental agreements (IEAs), it is necessary to analyze the dynamics of global emission level associated with the corresponding abatement process. We model multilateral collaboration among countries as a two-level coalitional game of heterogeneous players with a stepwise emission reduction over a finite and discretized period of time. The formed coalition is assumed to hold a leader's position in the game, and the players that did not join the agreement (free-riders) are assumed to accept a position of the followers. To analyze fulfillment of the emission reduction targets, we construct a time-consistent abatement scheme,…
Prices and Pareto optima
2006
We provide necessary conditions for Pareto optimum in economies where tastes or technologies may be nonconvex, nonsmooth, and affected by externalities. Firms can pursue own objectives, much like the consumers. Infinite-dimensional commodity spaces are accommodated. Public goods and material balances are accounted for as special instances of linear restrictions.
Religion and the Scandinavian Welfare State: Public Support for Socio-economic Rights in Times of Migration
2020
The theme of this article is the legitimisation of social and economic rights within the context of the Scandinavian welfare state. This problem has become more prominent in the light of the recent influx of immigrants from countries in the Middle East and Africa dominated by other religious and cultural traditions than Lutheran Protestantism. Two questions are discussed in the article. First, what role has religion played vis-a-vis the development of the welfare states in Scandinavia? Second, in what ways have recent immigration trends influenced popular support for welfare provision and social rights?
Movilidad humana: una revisión teórica aplicable de los flujos migratorios en España
2020
El texto tiene el objetivo de realizar una revisión teórica aplicable entorno a las migraciones en el contexto particular español. Se ha realizado una revisión bibliográfica aplicable disponible en torno al tema, con el fin de ofrecer una recopilación y selección de la información disponible a este respecto partiendo de la dicotomía que haría en su momento López de Lera (1995), los que “vienen a descansar y los que vienen a trabajar”. Es importante porque el desarrollo teórico de sendas perspectivas de la migración es divergente. Este es el aporte del texto, realizar un recorrido por los dos caminos migratorios y delimitar las principales corrientes.
