This paper focuses on problems associated with nonresponse in Contingent Valuation surveys. The results from a telephone follow-up survey show that value inference can be considerably improved by information on nonrespondents' attitudes. 相似文献

This paper investigates the relative importance of scheduled U.S. macroeconomic news releases for stock valuation. The study
focuses on 11 macroeconomic announcements selected on the basis of the previous literature and the Bureau of Labor Statistics
classifications of major economic indicators. The paper shows that five out of the 11 announcements have significant influence
on stock valuation. These are the Employment Report, NAPM (manufacturing), Producer Price Index, Import and Export Price Indices,
and Employment Cost Index. Of these six announcements, the Employment Report and NAPM (manufacturing) exert the greatest influence.
The time of the announcement, measured by days from the beginning of the month to the release day, has a moderating impact
on the relationship between macroeconomic announcements and its importance. 相似文献

We search forstrategy-proof solutions in the context of (many-to-one) matching problems (Gale and Shapley, 1962). In this model, whenever the firms can
hire as many workers as they want (the capacities are unlimited) the stable set is a singleton. There exists aPareto efficient, individually rational, andstrategy-proof matching rule if and only if the capacities are unlimited. Furthermore, whenever the capacities unlimited, the matching rule
which selects the unique stable matching is the only matching rule that isPareto efficient, individually rational, andstrategy-proof. 相似文献

Zusammenfassung Es sei {F
,(x); –<<, >0} mitF
,(x)=F((x–)/)–F(x) eine standardisierte Verteilungsfunktion — die Familie der zulässigen Verteilungsfunktionen. Der (früher eingeführte) verallgemeinerte nichtzentralet-Test für die Hypothese {PP
0} mitP:=F
,(x
0) gegen die Alternative {P>P
0} zum Niveau wird mit dem entsprechenden nichtparametrischen Test (Test für die Hypothese {pP
0} über den Parameterp einer Binomialverteilung gegen die Alternative {p>P
0}) verglichen. Für dent-Test wird die relative asymptotische Effizienz bestimmt.Beide Tests lassen sich als Tests für das zur WahrscheinlichkeitP
0 gehörende Quantil einer Verteilungsfunktion interpretieren. Der klassische zentrale Student-Test ergibt sich als Spezialfall (F(x)=(x),P
0=0,5).
Summary Let {F ,(x);–<<, >0} withF ,(x 0):=F((x–)/–F(x) a standarized distribution function — the family of admissible distribution functions. The (earlier introduced) generalized noncentralt-test for the hypothesis {PP 0} withP:=F ,(x 0) against the alternative {P>P 0} at level of significance is compared with the corresponding nonparametric test (Binomial test). The relative asymptotic efficiency of thet-test is determined. Both kinds of tests can be interpreted as quantiltests. In caseF(x)=(x),P 0=0,5 one gets the classical central Student-test.相似文献

On a clear day you might see an environmental Kuznets curve 总被引:1,自引:0,他引:1
We shed some new light on the Environmental Kuznets curve (EKC) and show how it can be viewed as a particular form of equilibrium
relationship, where technology and preference parameters determine the shape of the curve. In contrast to most of the literature
on the EKC, we estimate a theoretically consistent model on long-run data (Swedish sulfur emission, covering the period 1900–2002).
Furthermore, we test and date structural change. The model suggests four regimes, 1900–1918, 1919–1933, 1934–1967 and 1968–2002,
generating four rather different patterns for pollution over time. The policy-conclusions are consonant with Pearce’s general
view about the EKC: there is no theoretical presumption that it has an inverted U shape, nor should any country try to “grow
out of the environmental problems” without analyzing the benefits and costs of so doing. 相似文献

Green net national product was thought to be one way of measuring sustainable income. However, David Pearce understood that
a better measure of sustainable development was to look at what a generation is leaving in form of capital assets to later
generations. In this article, his arguments and insights are highlighted against recent theoretical advances. 相似文献

The dynamic behavior of a simple macroeconomic disequilibrium model is analyzed in which consumers' changes in money holdings constitute the dynamic link between any two periods. It is shown that, under constant government consumption, a constant production function (no investment), and fixed prices and wages, stationary states of Keynesian unemployment are stable whereas those of repressed inflation are globally unstable. Possibilities of unemployment and output cycles are indicated for fixed wages as well as for some very simple class of wage and price adjustment mechanisms. 相似文献
