Work Meaningfulness as a Key Enhancer of Ethical Values in Business

Despite abundant research on work meaningfulness, the link between work meaningfulness and general ethical attitude at work has not been discussed so far. In this article, we propose a theoretical framework to explain how work meaningfulness contributes to enhanced ethical behavior. We argue that by providing a way for individuals to relate work to one's personal core values and identity, work meaningfulness leads to affective commitment - the involvement of one's cognitive, emotional, and physical resources. This, in turn, leads to engagement and so facilitates the integration of one's personal values in the daily work routines, and so reduces the risk of unethical behavior. On the contrary, anomie, that is, the absence of meaning and consequently of personal involvement, will lead to lower rational commitment rather than affective commitment, and consequently to disengagement and a-morality. We conclude with implications for the management of ethical attitudes.

Ideas, Possibilities and Limitations of Sustainable Economic Policy – the Example of Ecological Economics

A mesura que el suport del creixement econòmic constitueix un objectiu fonamental de la formulació de polítiques econòmiques, cal assenyalar que aquest tipus de creixement està limitat naturalment per un planeta finit. Aquest article argumenta que, des del punt de vista de la justícia intergeneracional, la realització d'un concepte de desmaterialització i, com a efecte, d'una economia que no creix (en el sentit de dissociació absoluta del creixement econòmic i consum d'energia i materials) es pot justificar. Per tant, el creixement pot ser també entesa com la millora de la qualitat de vida sobretot en comptes d'ampliar quantitats escarpats de sortida. Per tant, una dràstica reducció del cabal de material es necessita, sobretot en els països d'alts ingressos. Després de presentar alguns crítica de les propostes, en el focus d'aquest article es dibuixen en els arguments de per què la política econòmica en el futur han de ser etiquetats com "ecològic" i, a continuació, les opcions de posar en acció les idees del teòric presentat marc en tasques manejables polítiques seran discutides. En aquest cas, s'argumentarà que l'enfocament clàssic de internalització d'efectes externs sovint seguides de decisions de política econòmica ortodoxa no és completament capaç de reflectir canvis ecològics en les estructures de preus dels mercats. Per tant, formal (industrial i l'establiment de la política de consum) i institucions informals (llars) representen punts clau de la política econòmica sostenible, assenyalant l'individu com així com la responsabilitat col · lectiva per omplir aquest buit substancial.

Crises as a disease of the body politick: a metaphor in the history of nineteenth century economics

This paper examines the use of the medical metaphor in the early theories of crises. It first considers the borrowing of medical terminology and generic references to disease which, notwithstanding their relatively trivial character, illustrate how crises were originally conceived as disturbances (often of a political nature) to a naturally healthy system. Then it shows how a more specific metaphor, the fever of speculation, shifted the emphasis by treating prosperity as the diseased phase, to which crises are a remedy. The metaphor of the epidemic spreading of the disease introduced the theme of the cumulative character of both upswing and downswing, while the similitude with intermittent fevers accounted for the recurring nature of crises. Finally, the paper examines how the medical reflections on the causality of diseases contributed to the epistemology of crises theory, and reflects on the metaphisical shift accompanying the transition from the theories of crises to the theories of cycles.

Economics of public governance with strategic production of information: four essays

SUMMARY This paper analyses the outcomes of the EEA and bilateral agreements vote at the level of the 3025 communities of the Swiss Confederation by simultaneously modelling the vote and the participation decisions. Regressions include economic and political factors. The economic variables are the aggregated shares of people employed in the losing, Winning and neutral sectors, according to BRUNETTI, JAGGI and WEDER (1998) classification, Which follows a Ricardo-Viner logic, and the average education levels, which follows a Heckscher-Ohlin approach. The political factors are those used in the recent literature. The results are extremely precise and consistent. Most of the variables have the predicted sign and are significant at the l % level. More than 80 % of the communities' vote variance is explained by the model, substantially reducing the residuals when compared to former studies. The political variables do have the expected signs and are significant as Well. Our results underline the importance of the interaction between electoral choice and participation decisions as well as the importance of simultaneously dealing with those issues. Eventually they reveal the electorate's high level of information and rationality. ZUSAMMENFASSUNG Unser Beitrag analysiert in einem Model, welches gleichzeitig die Stimm- ("ja" oder "nein") und Partizipationsentscheidung einbezieht, den Ausgang der Abstimmungen über den Beitritt zum EWR und über die bilateralen Verträge für die 3025 Gemeinden der Schweiz. Die Regressionsgleichungen beinhalten ökonomische und politische Variabeln. Die ökonomischen Variabeln beinhalten die Anteile an sektoriellen Arbeitsplatzen, die, wie in BRUNETTI, JAGGIl.1I1d WEDER (1998), in Gewinner, Verlierer und Neutrale aufgeteilt Wurden, gemäß dem Model von Ricardo-Viner, und das durchschnittliche Ausbildungsniveau, gemäß dem Model von Heckscher-Ohlin. Die politischen Variabeln sind die in der gegenwärtigen Literatur üblichen. Unsere Resultate sind bemerkenswert präzise und kohärent. Die meisten Variabeln haben das von der Theorie vorausgesagte Vorzeichen und sind hoch signifikant (l%). Mehr als 80% der Varianz der Stimmabgabe in den Gemeinden wird durch das Modell erklärt, was, im Vergleich mit früheren Arbeiten, die unerklärten Residuen Wesentlich verkleinert. Die politischen Variabeln haben auch die erwarteten Vorzeichen und sind signifikant. Unsere Resultate unterstreichen die Bedeutung der Interaktion zwischen der Stimm- und der Partizipationsentscheidung, und die Bedeutung diese gleichzeitig zu behandeln. Letztendlich, belegen sie den hohen lnformationsgrad und die hohe Rationalität der Stimmbürger. RESUME Le présent article analyse les résultats des votations sur l'EEE et sur les accords bilatéraux au niveau des 3025 communes de la Confédération en modélisant simultanément les décisions de vote ("oui" ou "non") et de participation. Les régressions incluent des déterminants économiques et politiques. Les déterminants économiques sont les parts d'emploi sectoriels agrégées en perdants, gagnants et neutres selon la classification de BRUNETTI, JAGGI ET WEDER (1998), suivant la logique du modèle Ricardo-Viner, et les niveaux de diplômes moyens, suivant celle du modèle Heckscher-Ohlin. Les déterminants politiques suivent de près ceux utilisés dans la littérature récente. Les résultats sont remarquablement précis et cohérents. La plupart des variables ont les signes prédits par les modèles et sont significatives a 1%. Plus de 80% de la variance du vote par commune sont expliqués par le modèle, faisant substantiellement reculer la part résiduelle par rapport aux travaux précédents. Les variables politiques ont aussi les signes attendus et sont aussi significatives. Nos résultats soulignent l'importance de l'interaction entre choix électoraux et décisions de participation et l'importance de les traiter simultanément. Enfin, ils mettent en lumière les niveaux élevés d'information et de rationalité de l'électorat.

Reaction-diffusion waves of advance in the transition to agricultural economics

In a previous paper [J.Fort and V.Méndez, Phys. Rev. Lett. 82, 867 (1999)], the possible importance of higher-order terms in a human population wave of advance has been studied. However, only a few such terms were considered. Here we develop a theory including all higher-order terms. Results are in good agreement with the experimental evidence involving the expansion of agriculture in Europe

On the foundations of well-being economics and policy

When one wishes to implement public policies, there is a previous need of comparing different actions and valuating and evaluating them to assess their social attractiveness. Recently the concept of well-being has been proposed as a multidimensional proxy for measuring societal prosperity and progress; a key research topic is then on how we can measure and evaluate this plurality of dimensions for policy decisions. This paper defends the thesis articulated in the following points: 1. Different metrics are linked to different objectives and values. To use only one measurement unit (on the grounds of the so-called commensurability principle) for incorporating a plurality of dimensions, objectives and values, implies reductionism necessarily. 2. Point 1) can be proven as a matter of formal logic by drawing on the work of Geach about moral philosophy. This theoretical demonstration is an original contribution of this article. Here the distinction between predicative and attributive adjectives is formalised and definitions are provided. Predicative adjectives are further distinguished into absolute and relative ones. The new concepts of set commensurability and rod commensurability are introduced too. 3. The existence of a plurality of social actors, with interest in the policy being assessed, causes that social decisions involve multiple types of values, of which economic efficiency is only one. Therefore it is misleading to make social decisions based only on that one value. 4. Weak comparability of values, which is grounded on incommensurability, is proved to be the main methodological foundation of policy evaluation in the framework of well-being economics. Incommensurability does not imply incomparability; on the contrary incommensurability is the only rational way to compare societal options under a plurality of policy objectives. 5. Weak comparability can be implemented by using multi-criteria evaluation, which is a formal framework for applied consequentialism under incommensurability. Social Multi-Criteria Evaluation, in particular, allows considering both technical and social incommensurabilities simultaneously.

Eager for fairness or revenge: psychological altruism in economics

To understand the human capacity for psychological altruism, one requires a proper understanding of how people actually think and feel. This paper addresses the possible relevance of recent findings in experimental economics and neuroeconomics to the philosophical controversy over altruism and egoism. After briefly sketching and contextualizing the controversy, we survey and discuss the results of various studies on behaviourally altruistic helping and punishing behaviour, which provide stimulating clues for the debate over psychological altruism. On closer analysis, these studies prove less relevant than originally expected because the data obtained admit competing interpretations such as people seeking fairness versus people seeking revenge. However, this mitigated conclusion does not preclude the possibility of more fruitful research in the area in the future. Throughout our analysis, we provide hints for the direction of future research on the question.

Swain: Stata module to correct the SEM chi-square overidentification test in small sample sizes or complex models. Statistical Software Components S457617, Boston College Department of Economics.

Swain corrects the chi-square overidentification test (i.e., likelihood ratio test of fit) for structural equation models whethr with or without latent variables. The chi-square statistic is asymptotically correct; however, it does not behave as expected in small samples and/or when the model is complex (cf. Herzog, Boomsma, & Reinecke, 2007). Thus, particularly in situations where the ratio of sample size (n) to the number of parameters estimated (p) is relatively small (i.e., the p to n ratio is large), the chi-square test will tend to overreject correctly specified models. To obtain a closer approximation to the distribution of the chi-square statistic, Swain (1975) developed a correction; this scaling factor, which converges to 1 asymptotically, is multiplied with the chi-square statistic. The correction better approximates the chi-square distribution resulting in more appropriate Type 1 reject error rates (see Herzog & Boomsma, 2009; Herzog, et al., 2007).

Do institutions and culture matter for business cycles?

We examine the relationship between institutions, culture and cyclical fluctuations for a sampleof 45 European, Middle Eastern and North African countries. Better governance is associated withshorter and less severe contractions and milder expansions. Certain cultural traits, such as lack ofacceptance of power distance and individualism, are also linked business cycle features. Businesscycle synchronization is tightly related to similarities in the institutional environment. Mediterraneancountries conform to these general tendencies.

The economics of anti-parasite defences in animal societies

RESUME : De nombreuses espèces animales vivent en groupe. Du simple grégarisme aux colonies hautement intégrées de fourmis, la vie sociale a atteint des degrés divers de complexité. Les nombreuses interactions entre membres d'une société favorisent la transmission de parasites. Cela représente un coût potentiel de la vie sociale. Cette thèse s'intéresse aux défenses permettant de réduire le coût du parasitisme dans les colonies de fourmis ainsi qu'à la manière dont le parasitisme a pu façonner certains aspects de ces sociétés. Les colonies de fourmis des bois (Forimica paralugubris) contiennent de grandes quantités de résine de conifères. Cette résine réduit la densité microbienne dans le nid et augmente la survie des ouvrières lors d'infections parasitaires. Dans cette thèse, nous montrons, d'une part, que les ouvrières collectent activement la résine et que ce comportement est plutôt préventif que curatif et, d'autre part, que la résine permet aux ouvrières une utilisation moindre de leurs défenses immunitaires. Ces résultats permettent de conclure que ce comportement réduit l'exposition au parasitisme et qu'il a une fonction adaptative. L'émergence d'un tel comportement de médication chez une espèce d'insectes sociaux illustre le fait que la socialité, bien yue provoquant une exposition accrue au parasitisme, permet également l'émergence de mécanismes sociaux de défense. II a été suggéré que la présence de plusieurs reines au sein d'un même nid (polygynie) améliore la résistance aux parasites en augmentant la diversité génétique au sein de la colonie. En accord avec cette hypothèse, nous montrons qu'une augmentation de la diversité génétique au sein de groupes expérimentaux de Formica selysi améliore leur survie lors d'une infection parasitaire. Cependant, nous suggérons également que sur le terrain, d'autres facteurs corrélés à la polygynie ont des effets antagoniques sur la résistance. Nous montrons par exemple que les ouvrières polygynes semblent avoir une capacité moindre à monter une réponse immunitaire. Certains aspects de la reproduction des fourmis ont pu également être façonnés par le parasitisme. L'accouplement n'a lieu que lors d'une courte période au début de la vie adulte, généralement à l'extérieur de la colonie. Les reines stockent ensuite le sperme et l'utilisent parcimonieusement au cours de leur vie alors que les males meurent rapidement. Nous montrons que les défenses immunitaires des reines de fourmis des bois (F. paralugubris) sont fortement affectées par l'accouplement. Ces modulations immunitaires sont probablement liées à une augmentation de l'exposition au parasitisme lors de l'accouplement ainsi qu'à des blessures copulatoires. I1 semble donc que l'accouplement soit accompagné de coûts immunitaires pour les reines. Dans son ensemble, cette thèse illustre la diversité des mécanismes de défenses contre les parasites dans les sociétés de fourmis. La vie sociale, en offrant un nouveau niveau d'interaction, permet en effet l'émergence d'adaptations originales. Cela explique probablement le grand succès écologique des espèces sociales. SUMMARY : Sociality is widespread among animals and has reached variable degrees of complexity, from loose social Groups to highly integrated ant colonies. The many interactions between members of a social group promote the spread of parasites, but social life also permits the evolution of original defence mechanisms. This thesis sheds light on how ant colonies defend themselves against parasites, and on how parasitism shapes certain aspects of these societies. Wood ants nests (Formica paralugubris) contain large amounts of conifer resin which reduces the microbial density in ant nests and enhances the survival of ants challenged by some pathogens. We show that resin is actively collected by workers and that resin collection is rather a prophylactic than a curative behaviour. Moreover, we suggest that resin reduces the use of the immune defences of workers. Altogether, these results indicate that the use of resin is a collective adaptation to prevent the spread of parasites. The emergence of medication in a social insect species illustrates that sociality does not only increase the exposure to parasites but also allows the emergence of social mechanisms to counter this threat. The number of reproducing queens per colony is a variable trait in ants. It has been suggested that polygyny (the occurrence of multiple queens within a colony), by increasing the colonial genetic diversity, improves disease resistance. In line with this hypothesis, we show that in a socially polymorphic ant (Formica selysi), an experimental increase of colony genetic diversity enhances disease resistance. However, we also suggest that factors covarying with queen number variation in the field have antagonistic effects on parasite resistance. We show for instance that polygyne workers seem to have lower immune defences. Parasites may also shape some aspects of ant queen reproductive biology. Ant queens mate at the beginning of their adult life, usually outside of the colony, and store sperm for several years to fertilize eggs. Males die shortly after mating and queens never remate later in life, which drastically reduces sexual conflicts. Moreover, mating and nest founding occur away from the collective defence mechanisms of the natal colony and might be associated with an increased risk of parasitism. We show that mating affects the immune defences of wood ant queens (F. paralugubris) in multiple ways that are consistent with mating wounds and increased risk of parasitism. We suggest that mating is associated with immunity costs in ants, despite the reduced level of sexual conflicts. Altogether, my thesis illustrates the diversity of anti-parasite mechanisms in ant societies. This sheds light on how sociality, by offering a new level of interactions, allows the evolution of original adaptations, which may explain the wide ecological success of social species.

15 years of new growth economics: What have we learnt?

This paper evaluates the empirical and theoretical contributions of theEconomic Growth Literature since the publication of Paul Romer s seminalpaper in 1986.

Testing calibrated general equilibrium models

This paper illustrates the philosophy which forms the basis of calibrationexercises in general equilibrium macroeconomic models and the details of theprocedure, the advantages and the disadvantages of the approach, with particularreference to the issue of testing ``false'' economic models. We provide anoverview of the most recent simulation--based approaches to the testing problemand compare them to standard econometric methods used to test the fit of non--lineardynamic general equilibrium models. We illustrate how simulation--based techniques can be used to formally evaluate the fit of a calibrated modelto the data and obtain ideas on how to improve the model design using a standardproblem in the international real business cycle literature, i.e. whether amodel with complete financial markets and no restrictions to capital mobility is able to reproduce the second order properties of aggregate savingand aggregate investment in an open economy.

The challenge of representative design in psychology and economics

The demands of representative design, as formulated by Egon Brunswik (1956), set a high methodological standard. Both experimental participants and the situations with which they are faced should be representative of the populations to which researchers claim to generalize results. Failure to observe the latter has led to notable experimental failures in psychology from which economics could learn. It also raises questions about the meaning of testing economic theories in abstract environments. Logically, abstract tests can only be generalized to abstract realities and these may or may not have anything to do with the empirical realities experienced by economic actors.
