In this paper we construct a large Bayesian Vector Autoregressive model (BVAR) for the Euro area that captures the complex dynamic inter-relationships between the main components of the Harmonized Index of Consumer Prices (HICP) and their determinants. The model generates accurate conditional and unconditional forecasts in real-time. We find a significant pass-through effect of oil-price shocks on core inflation and a strong Phillips curve during the Great Recession.  相似文献

Hybrid marketplaces, such as Amazon's and Zalando's stores or Apple's and Google's app stores, which distribute their own products and services in competition with those of third-party sellers, play a significant and growing role in the Internet economy. This paper shows that, other things equal, such platforms would maximize their profits if they lowered the fees charged to sellers and the prices charged to consumers in response to cooperation agreements between third-party sellers: horizontal mergers or collusive agreements. It also shows that such cooperation can be pro-competitive when the platform is a vertically integrated gatekeeper, adopts the agency business model, is a close competitor to the third-party sellers it hosts, and observes (or correctly anticipates) the third-party sellers' agreement. The discussion here is of significant policy relevance, since third-party sellers in online marketplaces may find it easier to collude and may respond to the bargaining power of certain gatekeeper platforms by merging their activities.  相似文献

One of the necessary features of markets to produce efficient pricing is competition between information-based investors who quickly impound new information into price. However, a significant proportion of funds invested in today’s equity markets are in the hands of managers who pursue a style that utilises little or none of the available information. We simulate such a market where the funds are being managed using the following three investment styles: fundamental, momentum and index. We confirm that the major pricing anomalies that have been highlighted previously in the literature are a natural consequence of competition between managers utilising these three investment styles. More importantly, we show that this situation is unlikely to change as long as markets continue to be dominated by costly active managers with clients who pursue outperformance.  相似文献

We suggest that understanding unethical behavior in organizations involves understanding how people view themselves and their relationships with others, a concept known as self-construal. Across multiple studies, employing both field and laboratory settings, we examine the impact of three dimensions of self-construal (independent, relational, and collective) on unethical behavior. Our results show that higher levels of relational self-construal relate negatively to unethical behavior. We also find that differences in levels of relational self for men and women mediate gender differences in unethical behavior. We discuss both the theoretical and practical implications of these findings.  相似文献

Economic inequalities are engendered by a complex process, characterised by several steps and involving the interaction of several factors. The best indicator of individual economic well-being is disposable equivalised income. Evidence shows that welfare states retain a crucial function in Europe and that they have been central in limiting the detrimental effects of the financial crisis on disposable income distribution.  相似文献

We seek to design and implement a WTP elicitation instrument closely resembling an actual grocery shopping experience. An incentive-compatible choice experiment is used to elicit values for a non-GM attribute and a country-of-origin attribute of Canola oil. The choice context is varied to assess whether revealed-preference choice experiments are affected by choice variety. A median premium for non-GM Canola oil is found to approximate C$0.45 or C$0.62/liter according to the choice variety context; different country-of-origin effects are also found as choice context varies. Hypotheses as to why these significant effects of choice contexts occur are suggested.
Nous cherchons à concevoir et à mettre en application un instrument de révélation de la VDP qui ressemble étroitement aux choix que fait un consommateur lorsqu'il effectue son marché. Nous avons utilisé une méthode expérimentale compatible avec les incitations des participants afin de découvrir la valeur accordée à deux caractéristiques de l'huile de canola: non génétiquement modifiée et étiquetée selon le pays d'origine. La liste des choix est variée afin d'évaluer si les préférences révélées sont influencées par la gamme de choix. La prime médiane de l'huile de canola non génétiquement modifiée est d'environ 0,45 $CAN ou 0,62 $CAN le litre selon les choix proposés. Différents pays d'origine figurent aussi dans cette liste de choix. Nous avons formulé des hypothèses quant aux raisons pour lesquelles la gamme de choix a des effets importants.  相似文献

Habit persistence is related to recurring food safety incidents in the context of the initial three cases of bovine spongiform encephalopathy (BSE) in Canadian cows. We test Engel functions, using generalized method of moments procedures, to analyze the dynamics of monthly beef expenditure shares of a sample of Canadian households during years 2002 through 2005. From microlevel panel data which followed meat expenditures by Canadian households before and after the first three BSE cases, which were discovered in 2003 and 2005, it is seen that households’ reactions to these followed a similar general pattern: households reduced beef purchase expenditures following the discovery of BSE but expenditures subsequently recovered. Following the initial BSE event, we identify an immediate negative impact on beef expenditures. However, in the case of the second two BSE events, this negative impact was not evident until two months after the BSE announcements. The results suggest that habit persistence initially limited households’ reductions of beef purchases following the first BSE event. However, households with higher beef expenditure shares reduced expenditure more than others following the second two BSE events, suggesting that habitual patterns of high levels of consumption tended to change with the recurrence of these food safety events. La persistance des habitudes de consommation est liée aux incidents de sécurité alimentaire récurrents dans le contexte des trois premiers cas d’ESB décelés chez des bovins canadiens. À l’aide de la méthode des moments généralisés, nous avons estimé des courbes d’Engel pour analyser la dynamique des parts de dépenses mensuelles en viande de b?uf auprès d’un échantillon de ménages, au cours de la période de 2002 à 2005. D’après un panel de microdonnées sur les dépenses en viande des ménages canadiens effectuées avant et après la découverte des trois premiers cas d’ESB en 2003 et en 2005, la réaction des ménages semble avoir suivi une tendance générale similaire, à savoir une diminution des dépenses en viande de b?uf après l’annonce des cas d’ESB, suivie d’une reprise. Après l’annonce du premier cas d’ESB, nous avons observé un impact négatif immédiat sur les dépenses en viande de b?uf. Par contre, dans les deux autres cas, l’impact négatif ne s’est fait sentir que deux mois après leur annonce. Les résultats autorisent à penser que la persistance des habitudes a limité la diminution des dépenses des ménages en viande de b?uf après l’annonce du premier cas d’ESB. Toutefois, les ménages qui avaient une part des dépenses en viande de b?uf élevée ont diminué leurs dépenses plus que les autres ménages après l’annonce des deuxième et troisième cas, ce qui laisse supposer que les comportements habituels de consommation élevée ont eu tendance à changer avec la récurrence de ces incidents de sécurité alimentaire.  相似文献

ABSTRACT ** :  This paper investigates the nonprofit wage gap suggesting a theoretical framework where, like in Akerlof (1984) , effort correlates not only with wages, but also with non-monetary compensations. These take the form of relational goods by-produced in the delivery of particular services. By paying higher non-pecuniary compensations, the nonprofit sector attracts intrinsically similarly skilled, but more motivated workers, able to provide in fact a similar (or potentially higher) level of effort than their counterparts in the forprofit sector. On an empirical ground, the paper provides a number of econometric tests that confirm the main predictions of the model in Italy's case. It adds to the available empirical literature by introducing in the analysis direct measures of non-pecuniary compensations and job satisfaction.  相似文献

Quality of health care is the product of several factors as the literature has long recognized. In this paper we focus on the relationship between quality and investment in health technology by analysing the optimal investment decision in a new health care technology of a representative hospital that maximizes its surplus in an uncertain environment. The new technology allows the hospital to increase the quality level of the care provided, but the investment is irreversible. The paper uses the framework of the real option literature to show how the purchaser might influence the quality level by setting a quality‐contingent long‐term contract with the hospital.The investment in new technology is in fact best incentivated within a long‐term contract where the number of treatments reimbursed depends on the level of investment made when the technology is new. In this way, asymmetry of information does not affect the outcome of the contract. In our model in fact the purchaser can verify the level of the investment only at the end of each period but the purchasing rule has an anticipating effect on the decision to invest.  相似文献

This article analyzes the impact of entrepreneurial optimism on the market for new issues. We find that the existence of optimists generates a new reason for entrepreneurs to own equity in their firms. We show that optimism is a natural explanation for why some new issues are underpriced and others overpriced. We also show that the impact of optimism on entrepreneurs' equity holdings depends on the number of optimists, absolute risk aversion, and cash flow variance. Optimism makes entrepreneurs worse off. In contrast, optimism can make outside investors better off when entrepreneurs signal firm value by retaining shares and underpricing.  相似文献
