Wherever taxi regulators cap the number of taxis, operating licences acquire economic value. In the UK, the Office of Fair Trading recommended legislative repeal of quantity caps, but the status quo continues. This article argues that licence values send an important signal to taxi regulators. 相似文献

Policies to reduce aggressive tax avoidance are increasingly being implemented or discussed in many countries around the world. Tax authorities hope that such policies will generate new tax revenue by increasing overall tax compliance. We present an experimental design to investigate the effect of a stylized anti-avoidance tax policy on tax compliance behavior. We highlight that anti-avoidance tax policies that reduce tax avoidance can also induce an increase in tax evasion (“substitution effect”), which limits the additional tax revenue these policies will generate. We show that the degree of substitution depends crucially on behavioral factors such as tax morale. Policymakers therefore also need to consider behavioral features while designing such policies and estimating their potential effects. 相似文献

The absence of female leaders in business and public life is conspicuous in Islamic societies. One explanation may be that Islam imposes legal and social inequality on men and women. However, a comparison of female entrepreneurship in pre‐Islamic society and in Mohammed's era shows that women occupied leadership roles before and after the establishment of Islam. Mohammed's wives were commercially astute, and Mohammed and his contemporaries respected the rights of women to make decisions regarding finances, matrimony and religious affiliation. The right of women to assume public leadership roles is compatible with Islam. 相似文献

In the second half of 2009, the entire media agenda in Germany was dominated by the swine flu, next to the German Federal Parliament elections. Criticism was voiced in the media against the pharmaceutical industry for lobbying the nationwide swine flu vaccination, which was widely considered nothing but a product of the industry’s lobbying power. In order to avoid the usual interviews with lobbyists, we attempted to apply a new methodological framework approach in analysing lobbying processes and key stakeholders in the public sphere—and outside. Crucial to the diversified approach, which involves quantitative content analysis of media coverage and press releases, are interviews with journalists, lobbyists’ network analysis and internet research on biographies. Although a conspiracy could not be conclusively proven, the results do indicate associations that validate the criticism of the industry’s lobbying activities. 相似文献

Der Klimawandel und das globale ?ffentliche Gut Klimaschutz genie?en gro?e Aufmerksamkeit in der ?ffentlichen Debatte. Klimaschutz
verursacht jedoch Kosten und es stellt sich die Frage, was die Menschen in Deutschland tats?chlich für Klimaschutz bereit
sind zu zahlen. Dieser Beitrag stellt eine neue Studie zur Ermittlung der realen Zahlungsbereitschaft für Klimaschutz vor
und diskutiert die Ergebnisse aus der Perspektive der Klimapolitik. 相似文献

In the Middle Ages, discourse on economics, such as it was, proceeded for the most part as an application of theological doctrine. But economic analysis as an independent discipline per se was taking shape in thirteenth‐century scholasticism. This is shown by a review of relevant sections of Thomas Aquinas’ Summa theologiae regarding property rights and the division of labour; wealth and income policies; consumer protection and fair trade; and the distinction between usurious and licit financial returns. 相似文献

Whereas empirical evidence on the effect of higher commodity prices on the long-run growth of commodity exporters is ambiguous, time series analyses using vector autoregressive (VAR) models have found that commodity booms raise income in the short run. In this paper we adopt panel error correction methodology to analyze global data for 1963 to 2008 to disentangle the short and long run effects of international commodity prices on output per capita. Our results show that commodity booms have unconditional positive short-term effects on output, but non-agricultural booms in countries with poor governance have adverse long-term effects which dominate the short-run gains. Our findings have important implications for non-agricultural commodity exporters with poor governance, especially in light of the recent wave of resource discoveries in low-income countries. 相似文献

Zusammenfassung Diese Arbeit ist die gekürzte Fassung einer Dissertation, die vom Autor 1968 unter gleichem Titel in Würzburg ver?ffentlicht
wurde.
Es ist nicht sinnovll, Mittelwerte für zuf?llige Variable auf der Sph?re in der üblichen Weise, wie z. B. für zuf?llige Variable
auf der reellen Achse, zu definieren.
W. Uhlmann [1964] bediente sich entscheidungstheoretischer Begriffe, um für zirkul?re zuf?llige Variable mittlere Winkel zu definieren,
die ihre Richtung unabh?ngig von der Wahl der Null-Richtung beibehalten. Die analoge Invarianzeigenschaft wird für alle hier
definierten Mittelwertbegriffe (mittlere Richtung, mittlerer Gro?kreis, Mittelachse, Mittelkreis) gesichert, indem einfache
Forderungen an die zu verwendenden Verlustfunktionen gestellt werden. Da als Sch?tzungen für diese Mittelwerte stets die entsprechenden
Mittelwerte der empirischen Verteilung auftreten, haben diese auch die gleiche Invarianzeigenschaft. Um die Diskrepanz zwischen
einer solchen Sch?tzung und dem zu sch?tzenden Mittelwert zu messen, werden neue Verlustfunktionen eingeführt. Es wird gezeigt,
da? alle eingeführten Sch?tzungen bezüglich mindestens einer Verlustfunktion unverf?lscht sind, d. h. der erwartete Verlust
wird minimal, wenn wir aus allen in Frage kommenden Objekten gerade den betreffenden Mittelwert gesch?tzt werden lassen. Dieser
minimale Verlust wird die Dispersion der Sch?tzung bezüglich dieser Verlustfunktion genannt. Es wird bewiesen, da? alle ermittelten
Dispersionen mindestens wien
−1/2 gegen Null gehen, wenn n gegen Unendlich strebt.
Summary This paper is shortened from an equally entitled dissertation which has been published by the author in 1968 at Würzburg. For random variables on the sphere it would make no sense to define means in the usual way as it is done e. g. for random variables on the real line. Introducing concepts of decision theory,W. Uhlmann [1964] defined mean angles for circular random variables the direction of which does not depend on the choice of the zero direction. Setting up simple conditions for the loss functions to be used, we ensure that all the means defined in the paper (mean directions, mean great circles, mean axes, mean circles) have the analogous invariance property. The estimators of these means are always the corresponding means of the empirical distribution, defined with respect to the same loss function and therefore they have the invariance property too. To measure the discrepance between an estimator and the estimated mean, new loss functions are introduced. It is shown that all the established estimators are unbiased with respect to at least one loss function, i. e. the expected loss is a minimum, if we take just the mean from all the things in question to be estimated by the regarded estimator. This minimum loss is called the dispersion of the estimator with respect to this loss function. It is proved, that all the calculated dispersions go to zero at least asn −1/2, ifn tends to infinity.相似文献
