An account on the taxonomy and molecular diversity of a marine rock-pool dweller, Tigriopus fulvus (Copepoda, Harpacticoida)
2019
[ES] El género de copépodos Tigriopus Norman, 1869 se distribuye en todo el mundo en charcas de rocas costeras y se considera que actualmente incluye 14 especies válidas. Tigriopus fulvus (Fischer 1860), con sus subespecies Tigriopus fulvus adriaticus Van Douwe 1913 y Tigriopus fulvus algiricus Monard 1935, y Tigriopus minutus Bozic 1960 han sido descritos para el área del Mediterráneo, pero la diversidad real del género es desconocida actualmente. El objetivo de este estudio fue evaluar la identidad real de las poblaciones mediterráneas de Tigriopus y dilucidar su taxonomía y patrón de diversidad genética. Con este fin, se secuenció un fragmento del gen de ADN mitocondrial (citocromo c oxi…
Oligopolio y tipos de interés en la banca española, 1942-1975
2001
El objetivo de este trabajo es analizar la posible utilización por parte de los bancos españoles de acuerdos monopolistas destinados a fijar los tipos de interés en el período comprendido entre el final de la guerra civil española y 1975. El segundo aspecto que va a abordar este artículo es la búsqueda de indicadores cuantitativos y cualitativod del grado de efectividad de dichos acuerdos colusivos. La principal conclusión que se obtiene es que a pesar de la existencia de un pacto entre las entidades bancarias para controlar los tipos de interés, respaldado por las propias autoridades franquistas, los principales bancos infringieron dichos acuerdos y compitieron vía precio en el mercado de …
Cannabis e terapia del dolore. Un singolare caso di limitazione del diritto alla cura.
2020
L’articolo descrive l’assetto del mercato della cannabis terapeutica definito dalla legislazione italiana, evidenziandone la dubbia compatibilità con l’ordinario paradigma accolto dalla Corte di Giustizia in materia di diritto della concorrenza. Gli elementi specializzanti alla base di tale devianza possono essere individuati nelle esigenze di tutela della salute pubblica, dell’ordine pubblico e della pubblica sicurezza: questa peculiarità (presupposta dalla normativa italiana e dalla sua matrice internazionale) non consente comunque di giudicare la regolazione della cannabis terapeutica conforme all’interpretazione consolidata degli articoli 49, 52, 56T.f.Ue e alla altrettanto stabile giur…
La tutela della concorrenza nella Repubblica Popolare Cinese
2014
La tesi dal titolo “La tutela della concorrenza nella Repubblica Popolare Cinese” si propone di affrontare l’intricato problema dell’armonizzazione dei principi della concorrenza in un sistema economico in via di transizione quale quello cinese. L’attenzione sulla questione è stata stimolata dall’emanazione della legge antimonopoli, entrata in vigore nell’agosto del 2008, che ha conosciuto le sue prime applicazioni concrete nel corso di questi primi cinque anni . Cercando di non lasciarsi sviare dalla tentazione di giudicare la normativa antitrust paese asiatico sul presupposto di una presunta superiorità degli ordinamenti dei paesi occidentali, che in materia posseggono una tradizioni di o…
Los derechos de monopolio en la Valencia del Antiguo Régimen: el ejemplo de Alfara y Burjasot durante el siglo XVII
1982
Como es sabido, los derechos de monopolio constituyen uno de los más sólidos pilares en que se basa el régimen señorial. No obstante, carecemos de estudios monográficos que se refieran a las características concretas que, en nuestra zona, reviste su administración y pongan de manifiesto el papel que desempeñan dentro del conjunto de relaciones económicas que, para la explotación de los señoríos, se establecen entre cualquier señor y sus vasallos. Dentro de estas coordenadas se inscribe la presente aportación, centrada en los antiguos señoríos de Alfara y Burjasot, dependientes del Colegio de Corpus Christi y sobre los que se guarda una completísima información en el Archivo del Colegio del …

More firms, more competition? The case of the fourth operator in France's mobile phone market
2010
Accepted, Forthcoming; International audience; To foster competition the French government authorized a fourth operator, ‘Free', to enter the country's mobile phone market at the end of 2009 alongside Orange, SFR and Bouygues Telecom (BT), who held respectively one-half, one-third and one-sixth of the market. By using a stylized model of France's phone market, we have examined what we call the regulator's nightmares and dreams. If Cournot competition is in place before Free's entry, minimizing the total profit fails to maximize the consumer surplus and the total surplus; the maximum most realistic price fall is 6.7% compared to three-way competition and could be 1.7% only; if Orange, SFR an…
Monopolistic competition and different wage setting systems
2010
In this paper, we present a disequilibrium unemployment model without labor market frictions and monopolistic competition in the goods market within an infinite horizon model of growth. We consider different wage setting systems and compare wages, the unemployment rate, and income per capita in the long-run at firm, sector, and national (centralized) levels. The aim of this paper is to determine under which conditions, the inverted-U hypothesis between unemployment and the degree of centralization of wage bargaining, reported by Calmfors and Driffill [Economic Policy, 6, 14¿61, 1988], is confirmed. Our analysis shows that a high degree of market power normally produces the inverted-U shape …
Unemployment, taxation and public expenditure in OECD economies
2008
Abstract This paper considers the financing of productive public goods and social benefits through different types of taxes in a model with unemployment. We incorporate unemployment, caused by the wage-setting behaviour of a monopolistic union, in a neoclassical growth model which integrates a quite detailed structure of taxes used to finance productive public expenditures and social transfers and parameterizes the inefficiency of government to transform taxes into public goods or transfers. The main conclusion is that the relationship between unemployment and labour taxes critically depends on the degree of government efficiency and the unions' perception on how taxes determine the welfare…
Multi-product firms and product variety
2008
The goal of this paper is to study the role of multi-product firms in the market provision of product variety. The analysis is conducted using the spokes model of non-localized competition proposed by Chen and Riordan (2007). Firstly, we show that multi-product firms are at a competitive disadvantage vis-a-vis single-product firms and can only emerge if economies of scope are sufficiently strong. Secondly, under duopoly product variety may be higher or lower with respect to both the first best and the monopolistically competitive equilibrium. However, within a relevant range of parameter values duopolists drastically restrict their product range in order to relax price competition, and as a…
