The causal relationship between Individual’s choice behavior and self-reported satisfaction: the case of residential mobility in the EU

One of the most persistent and lasting debates in economic research refers to whether the answers to subjective questions can be used to explain individuals’ economic behavior. Using panel data for twelve EU countries, in the present study we analyze the causal relationship between self-reported housing satisfaction and residential mobility. Our results indicate that: i) households unsatisfied with their current housing situation are more likely to move; ii) housing satisfaction raises after a move, and; iii) housing satisfaction increases with the transition from being a renter to becoming a homeowner. Some interesting cross-country differences are observed. Our findings provide evidence in favor of use of subjective indicators of satisfaction with certain life domains in the analysis of individuals’ economic conduct.

The Causal effect of education on aggregate income

Empirical studies assume that the macro Mincer return on schooling is con- stant across countries. Using a large sample of countries this paper shows that countries with a better quality of education have on average relatively higher macro Mincer coeficients. As rich countries have on average better educational quality, differences in human capital between countries are larger than has been typically assumed in the development accounting literature. Consequently, factor accumulation explains a considerably larger share of income differences across countries than what is usually found.

Aprendizaje causal en humanos: detectando la fuerza causal en contextos que varían en la tasa base del efecto

El beneficio principal de contar con una representación de la potencia causal (Cheng, 1997) es que ésta supone una descripción contexto-independiente de la influencia de una determinada causa sobre el efecto. Por lo tanto, una forma adecuada de poner a prueba la existencia de estos modelos mentales es crear situaciones en las que la gente observa o predice la efectividad de las causas diana en múltiples contextos. La naturaleza trans-situacional de la potencia trae consigo una serie de consecuencias testables que hemos puesto a prueba a lo largo de tres series experimentales. En la primera serie experimental investigamos la transferencia de la fuerza causal, aprendida en un contexto específico, a un contexto en el que la probabilidad o tasa base del efecto es diferente. Los participantes debían predecir la probabilidad del efecto dada la introducción de la causa en el nuevo contexto. En la segunda serie experimental estudiamos las estrategias utilizadas por las personas a la hora de descubrir relaciones causales. De acuerdo con el modelo de la potencia causal, si pretendemos descubrir la potencia de una causa, entonces lo más apropiado es introducirla en el contexto más informativo y menos ambiguo posible. En los distintos experimentos de la serie combinamos tanto contextos como causas probabilísticas y determinísticas. En la tercera serie experimental intentamos extender los hallazgos de Liljeholm & Cheng (2007), en los se encontró que la generalización entre contextos ocurre según las predicciones del modelo de potencia. Parece probable que el procedimiento de dos fases utilizado por los autores promueva la tendencia a ignorar algunos ensayos, generando artificialmente resultados consistentes con los esperados por la potencia. Además, cuando controlamos la P(E|C) independientemente de la potencia, el patrón de resultados se invirtió, contradiciendo lo esperado por el modelo de Cheng. En conclusión, existe cierta evidencia que apoya la existencia de modelos causales pero es necesario buscar formas adecuadas de poner a prueba estos modelos.

Mechanisms of antagonism of Pseudomonas fluorescens EPS62e against Erwinia amylovora, the causal agent of fire blight

Pseudomonas fluorescens EPS62e was selected during a screening procedure for its high efficacy in controlling infections by Erwinia amylovora, the causal agent of fire blight disease, on different plant materials. In field trials carried out in pear trees during bloom, EPS62e colonized flowers until the carrying capacity, providing a moderate efficacy of fire-blight control. The putative mechanisms of EPS62e antagonism against E. amylovora were studied. EPS62e did not produce antimicrobial compounds described in P. fluorescens species and only developed antagonism in King’s B medium, where it produced siderophores. Interaction experiments in culture plate wells including a membrane filter, which physically separated the cultures, confirmed that inhibition of E. amylovora requires cell-to-cell contact. The spectrum of nutrient assimilation indicated that EPS62e used significantly more or different carbon sources than the pathogen. The maximum growth rate and affinity for nutrients in immature fruit extract were higher in EPS62e than in E. amylovora, but the cell yield was similar. The fitness of EPS62e and E. amylovora was studied upon inoculation in immature pear fruit wounds and hypanthia of intact flowers under controlled-environment conditions. When inoculated separately, EPS62e grew faster in flowers, whereas E. amylovora grew faster in fruit wounds because of its rapid spread to adjacent tissues. However, in preventive inoculations of EPS62e, subsequent growth of EPS101 was significantly inhibited. It is concluded that cell-to-cell interference as well as differences in growth potential and the spectrum and efficiency of nutrient use are mechanisms of antagonism of EPS62e against E. amylovora

Causal assessment in finite extensive-form games

Two finite extensive-form games are empirically equivalent when theempirical distribution on action profiles generated by every behaviorstrategy in one can also be generated by an appropriately chosen behaviorstrategy in the other. This paper provides a characterization ofempirical equivalence. The central idea is to relate a game's informationstructure to the conditional independencies in the empirical distributionsit generates. We present a new analytical device, the influence opportunitydiagram of a game, describe how such a diagram is constructed for a givenextensive-form game, and demonstrate that it provides a complete summaryof the information needed to test empirical equivalence between two games.

La restitution archéologique comme modèle: le cas espagnol

Voici une réflexion autour des restitutions archéologiques et de leurs fonctions du point de vue de la recherche et du point de vue pédagogique. Nous abordons quelques cas méthodologiques propres à l’Espagne, pays où la tendance dominante est à la simple présentation des ruines, protégées ou restaurées suivant des critères d’intervention minimale. Néanmoins, plusieurs expériences de reconstruction ou reconstitution sur place ont été mises en place dans des années 1990. Plus précisément, ces expériences correspondent à deux modèles différents : la restitution sur place et la réplique. Quant au modèle de transfert, il n’a pas été adopté pour la restitution des sites archéologiques, mais il existe de nombreux exemples de monuments médiévaux et d’époque moderne qui ont été déplacés de leur emplacement d’origine.

The role of causal links in performance measurement models

Abstract Purpose: Several well-known managerial accounting performance measurement models rely on causal assumptions. Whilst users of the models express satisfaction and link them with improved organizational performance, academic research, of the realworld applications, shows few reliable statistical associations. This paper provides a discussion on the"problematic" of causality in a performance measurement setting. Design/methodology/approach: This is a conceptual study based on an analysis and synthesis of the literature from managerial accounting, organizational theory, strategic management and social scientific causal modelling. Findings: The analysis indicates that dynamic, complex and uncertain environments may challenge any reliance upon valid causal models. Due to cognitive limitations and judgmental biases, managers may fail to trace correct cause-and-effect understanding of the value creation in their organizations. However, even lacking this validity, causal models can support strategic learning and perform as organizational guides if they are able to mobilize managerial action. Research limitations/implications: Future research should highlight the characteristics necessary for elaboration of convincing and appealing causal models and the social process of their construction. Practical implications: Managers of organizations using causal models should be clear on the purposes of their particular models and their limitations. In particular, difficulties are observed in specifying detailed cause and effect relations and their potential for communicating and directing attention. They should therefore construct their models to suit the particular purpose envisaged. Originality/value: This paper provides an interdisciplinary and holistic view on the issue of causality in managerial accounting models.

Population Size and Civil Conflict Risk: Is There A Causal Link?

[spa] La estimación del impacto del tamaño de la populación sobre la probabilidad de conflicto civil se complica por el sesgo de endogeneidad y las variables omitidas. Este artículo trata el problema de causalidad utilizando métodos de variables instrumentales en un panel de 37 países del África Sub-sahariana en el período 1981-2004. Encontramos que un aumento de la población en un 1% aumenta la probabilidad de conflicto civil por un 5.2%.

El reposicionamiento: análisis conceptual y causal del fenómeno desde su origen hasta el (re)planteamiento actual

El present estudi té com a finalitat estudiar què és el reposicionament i quins són els factors que l’envolten. Pretén establir quines són les principals causes que condueixen a reposicionar una marca, així com també analitzar si el reposicionament és equivalent que quan va sorgir, o si pel contrari ha evolucionat, i com ho ha fet. Amb aquest estudi intentarem esbrinar com es reposicionen les marques en l’actualitat.

The causal factors of international inequality in CO2 emissions per capita: a regression-based inequality decomposition analysis

This paper uses the possibilities provided by the regression-based inequality decomposition (Fields, 2003) to explore the contribution of different explanatory factors to international inequality in CO2 emissions per capita. In contrast to previous emissions inequality decompositions, which were based on identity relationships (Duro and Padilla, 2006), this methodology does not impose any a priori specific relationship. Thus, it allows an assessment of the contribution to inequality of different relevant variables. In short, the paper appraises the relative contributions of affluence, sectoral composition, demographic factors and climate. The analysis is applied to selected years of the period 1993–2007. The results show the important (though decreasing) share of the contribution of demographic factors, as well as a significant contribution of affluence and sectoral composition.
