Más allá de la ley de May: disparidades curvilíneas y conflicto intrapartidista. El caso de Cataluña

Este artículo pretende contribuir al debate sobre el papel que desempeñan los adherentes y activistas y, de modo especial, a intentar plantear de nuevo el problema de su influencia dentro del partido. Para ello se revisa el trabajo de May (1973), sus posteriores desarrollos empíricos, y se intenta comprobar su validez en los principales ejes que marcan la competencia política catalana. Una vez comprobada la existencia de disparidades ideológicas en el caso catalán, el papel se centra en discutir algunas de las limitaciones del modelo de May. Ello permite, a su vez, sugerir la necesidad de elaborar un nuevo modelo de conflicto partidista que tenga presente tanto las relaciones de poder verticales (entre dirigentes y activistas) como horizontales (entre los mismos dirigentes). Para mostrar empíricamente las debilidades señaladas en el modelo de May, el análisis termina con un caso estudio que intenta ilustrar la dificultad de asociar disparidades con conflicto interno.

Influencia de la inmigración en la elección escolar

This empirical work studies the influence of immigrant students on individuals’ school choice in one of the most populated regions in Spain: Catalonia. It has estimated, following the Poisson model, the probability that a certain school, which immigrant students are already attending, may be chosen by natives as well as by immigrants, respectively. The information provided by the Catalonia School Department presents school characteristics of all the primary and secondary schools in Catalonia during the 2001/02 and 2002/03 school years. The results obtained support the evidence that Catalonia native families avoid schools attended by immigrants. Natives certainly prefer not to interact with immigrants. Private schools are more successful in avoiding immigrants. Finally, the main reason for non-natives’ choice is the presence of other non-natives in the same school.

Gestión de cambios y proyectos

Moltes inversions corporatives actuals són destinades a la millora de la gestió del canvi. Aquestes inversions són motivades per una carència històrica entre el conjunt recursos humans i les noves tecnologies tal com va reflexar l'estudi del MIT en 1992. L’objectiu del projecte és analitzar la gestió del canvi i projectes des d’un put de vista poc conegut per els enginyers. Direcció de l'equip humà, Procés de qualitat industrial, Programació extrema, Anàlisi de la cobertura dels Sistemes d’informació d’una companyia segons la seva estructura i estratègia empresarial, El mercat i les seves forces competitives, el retorn de la inversió, el cicle PDCA d’un projecte d’inversió, entre d’altres.

Dollfusentis chandleri Golvan, 1969 (Acanthocephala, Illiosentidae), Poecilancistrium caryophyllum (Diesing, 1850)(Cestoidea, Otobothriidae) and Callitetrarhynchus gracilis (Rudolphi, 1819)(Cestoidea, Dasyrhynchidae) as well as larval forms of Echinocephalus sp. (Nematoda, Gnathostomatidae) and Contracaecum sp. (Nematoda, Anisakidae) are also reported.

On the Relationship between Market Power and Bank Risk Taking

We analyse risk-taking behaviour of banks in the context of spatial competition. Banks mobilise unsecured deposits by offering deposit rates, which they invest either in a prudent or a gambling asset. Limited liability along with high return of a successful gamble induce moral hazard at the bank level. We show that when the market power is low, banks invest in the gambling asset. On the other hand, for sufficiently high levels of market power, all banks choose the prudent asset to invest in. We further show that a merger of two neighboring banks increases the likelihood of prudent behaviour. Finally, introduction of a deposit insurance scheme exacerbates banks’ moral hazard problem.

When is Monetary Policy All we Need?

We consider optimal monetary and scal policies in a New Keynesian model of a small open economy with sticky prices and wages. In this benchmark setting monetary policy is all we need - analytical results demonstrate that variations in government spending should play no role in the stabilization of shocks. In extensions we show, rstly, that this is even when true when allowing for in ation inertia through backward-looking rule-of-thumb price and wage-setting, as long as there is no discrepancy between the private and social evaluation of the marginal rate of substitution between consumption and leisure. Secondly, the optimal neutrality of government spending is robust to the issuance of public debt. In the presence of debt government spending will deviate from the optimal steady-state but only to the extent required to cover the deficit, not to provide any additional macroeconomic stabilization. However, unlike government spending variations in tax rates can play a complementary role to monetary policy, as they change relative prices rather than demand.

Más allá de los blogs personales: el periodismo participativo en la prensa electrónica

La irrupció d’Internet i les Noves Tecnologies, juntament amb una sèrie de factors socials, polítics i econòmics, han redefinit la clàssica relació unidireccional entre els mitjans i les seves audiències. En aquest context de democratització informativa, el tradicional monopoli dels mitjans ha desaparegut en pro d’un accés i una participació més gran dels lectors a la informació. Aquesta nova modalitat periodística, denominada Periodisme Participatiu o 2.0, promou tota una sèrie de canals o vies de comunicació -xats, fòrums, enquestes, entrevistes, lectors informadors etc.- que ofereixen a l’usuari la possibilitat de convertir-se en receptors i emissors de les noticies alhora. Aquesta intervenció activa de les audiències en el procés informatiu ha alterat, irremediablement, els patrons de consum informatiu i la naturalesa del periodisme tradicional

Bargaining and Conflict with Incomplete Information

This paper studies bargaining and conflict under incomplete information, provides an overview and a critical account of the literature on the topic and contributes with original research. We first revise models of mechanism design and sequential bargaining that take confrontation as final. Conflict and inefficiencies are to be expected in these models whenever parties have optimistic prospects on the outcome of the all-out conflict. After examining the causes and reasons for this optimism, we move to the analysis of the recent literature that considers the existence of limited confrontations that allow bargaining to resume. In the presence of private information, these limited conflicts convey information and thus become a bargaining instrument. The paper closes with a discussion on the related empirical literature, the challenges that it faces and some potential avenues for further research.

Minu, Startu and all that:- Pitfalls in estimating the sensitivity of a worker’s wage to aggregate unemployment

In this paper we show that the inclusion of unemployment-tenure interaction variates in Mincer wage equations is subject to serious pitfalls. These variates were designed to test whether or not the sensitivity to the business cycle of a worker’s wage varies according to her tenure. We show that three canonical variates used in the literature - the minimum unemployment rate during a worker’s time at the firm(min u), the unemployment rate at the start of her tenure(Su) and the current unemployment rate interacted with a new hire dummy(δu) - can all be significant and "correctly" signed even when each worker in the firm receives the same wage, regardless of tenure (equal treatment). In matched data the problem can be resolved by the inclusion in the panel of firm-year interaction dummies. In unmatched data where this is not possible, we propose a solution for min u and Su based on Solon, Barsky and Parker’s(1994) two step method. This method is sub-optimal because it ignores a large amount of cross tenure variation in average wages and is only valid when the scaled covariances of firm wages and firm employment are acyclical. Unfortunately δu cannot be identified in unmatched data because a differential wage response to unemployment of new hires and incumbents will appear under both equal treatment and unequal treatment.
