This paper assesses the effects of U.S. tax policy reforms on inequality over around three decades, from 1979 to 2007. It applies a new method for decomposing changes in government redistribution into (1) a direct policy effect resulting from policy changes and (2) the effects of changing market incomes. Over the period as a whole, the tax policy changes increased income inequality by pushing up the income share of high‐income earners (the top 20%). (JEL H23, H31, H53, P16) 相似文献

A European Social Survey (ESS)—based study of Clark and Lelkes on the European level showed a double positive connection between religion and life-satisfaction: not only did a personal involvement have a positive impact, but there was also a regional externality. Even atheists seemed to be happier in areas with many religious people. However, the regional structure of the ESS can be seen as methodologically doubtful. We therefore replicated the study with more rich German data. In our study we confirm the positive individual effect of religion, but we did find a negative regional externality. However, further analysis revealed, this was an effect of an omitted variable: the degree of urbanization. In a more detailed approach we show that this effect is confined to areas with a protestant majority. We conclude that the positive degree of urbanization influence on life-satisfaction is presumably due to the chance for more political participation in the (protestant) city states in Germany. 相似文献

Some studies generate data that can be grouped into clusters in more than one way. Consider for instance a smoking prevention study in which responses on smoking status are collected over several years in a cohort of students from a number of different schools. This yields longitudinal data, also cross‐sectionaliy clustered in schools. The authors present a model for analyzing binary data of this type, combining generalized estimating equations and estimation of random effects to address the longitudinal and cross‐sectional dependence, respectively. The estimation procedure for this model is discussed, as are the results of a simulation study used to investigate the properties of its estimates. An illustration using data from a smoking prevention trial is given. 相似文献

We construct a model of rational choice under risk with biased risk judgement. On its basis, we argue that sometimes, a regulator
aiming at maximising social welfare should affect the environment in such a way that it becomes ‘less safe’ in common perception.
More specifically, we introduce a bias into each agent’s choice of optimal risk levels: consequently, in certain environments,
agents choose a behaviour that realises higher risks than intended. Individuals incur a welfare loss through this bias. We
show that by deteriorating the environment, the regulator can motivate individuals to choose behaviour that is less biased,
and hence realises risk levels closer to what individuals intended. We formally investigate the conditions under which such
a Beneficial Safety Decrease—i.e. a deteriorating intervention that has a positive welfare effect—exists. Finally, we discuss
three applications of our model. 相似文献

While scholarly attention to the role played by diasporans in facilitating cross-country trade has recently increased, the implicitness of this phenomenon has prevented many researchers from examining empirically how these processes actually work. Unlike previous studies that focus on diasporans from specific countries of origin, we take a different perspective on diasporans by looking beyond country boundaries. We focus on religious/cultural groupings, specifically on Muslim diasporans living in the West. We utilize a phenomenological driven qualitative research approach to investigate the effects of Muslim diasporans on the internationalization processes of firms from Organization of Islamic Conference countries in the context of the halal industry. Our exploratory study provides some evidence for (1) the boundary spanner roles played by Muslim diasporans within the halal industry across more than dyadic country contexts and (2) for Rahnema's (2006) triple identity theory. 相似文献

Sequential choice processes are ubiquitous in consumer decision making. In each attribute decision, consumers are often faced with different numbers of options which they must trade off in order to make the best possible choice. Thereby, complicated high variety choices at the beginning of a choice process produce a larger trade-off conflict and, thus, initially a greater mental depletion than more simple low variety choices. We examine the strength of mental depletion in sequential choices on individuals’ perceived attractiveness of the firm’s recommended default option at a target choice. We show that consumers who are confronted with difficult high variety choices early in the decision sequence followed by low variety choices initially deplete more than consumers who encounter exactly the same attribute decisions in reverse. As a result, depleted consumers are more likely to fall prey to the recommended default or some perceptually focal options close to the default anchor at target choice succeeding a sequence of decisions. 相似文献

New tests are proposed for the specification of the intraday price process of a risky asset,
based on open, high, low, and close prices. Under the null of a Brownian process we derive two stochastically
independent, unbiased volatility estimators. For a Hausman specification test we prove its equivalence
with an F-test, consider its robustness against variation in drift and volatility, and analyze the power
against an Ornstein–Uhlenbeck process, as well as a random walk with alternative distributions. 相似文献

Zusammenfassung Rechtsansprüche gegen Fluggesellschaften und Flugzeughersteller in Folge einer Flugzeugkatastrophe richten sich nach einer
Flut rechtlicher Bestimmungen, die aus internationalen Abkommen, Vereinbarungen zwischen Fluglinien sowie aus Bundes- und
Landesrecht resultieren. Die jeweilige Rechtsgrundlage in einem spezifischen Fall h?ngt von verschiedenen Umst?nden ab, die
mit einem Unfall verbunden sind. Es überrascht daher nicht, dass zugesprochene Schadensersatz- und Schmerzensgeldzahlungen
an die Angeh?rigen der Opfer von Fall zu Fall erheblich divergieren. In unserer Studie mit U.S.-amerikanischen Daten untersuchen
wir, inwieweit der kurz- und langfristige Erfolg von Fluggesellschaften und Flugzeugherstellern durch Flugzeugkatastrophen
beeinflusst wird und wir eruieren diejenigen Determinanten, die Performanceunterschiede erkl?ren k?nnen. Verwandte Untersuchungen
haben sich weitgehend auf Effekte für Markennamen oder steigende Versicherungspr?mien als Ursachen für Aktienkursverluste
konzentriert. Unsere Ergebnisse zeigen darüber hinaus, dass das regulatorische Umfeld einer spezifischen Unglückssituation
erheblichen Einfluss darauf hat, wie Finanzm?rkte reagieren. Die Reaktionen der Marktteilnehmer weisen darauf hin, dass die
unterschiedlichen Berechnungsgrundlagen für die Opferentsch?digung recht klar erkannt werden.
The role of aviation laws and legal liability in airplane accidents: A financial market perspective
Summary Legal liability claims against airlines and airplane manufacturers following an aviation disaster are determined through a myriad of international treaties, intercarrier agreements, and federal and state laws. Which law applies in a specific situation depends on various circumstances surrounding the accident. As a result, pecuniary and non-pecuniary damage awards for the families of the accident victims may vary substantially from case to case. Using U.S. data, our study examines how aviation disasters affect the short and long-term performance of airlines and airplane manufacturers and explores the factors that drive the performance differences. While prior research has largely focused on brand name effects and rising insurance premiums as possible determinants of stock price losses, our results suggest that the regulatory environment that applies to a given aviation accident has a significant impact on how the market reacts to its announcement. Inequities in the valuation of a human life are clearly reflected in stock price reactions. While recent regime changes have helped eliminate some of these imbalances further reform may be necessary.
