We analyse post-war Dutch migration to New Zealand. We document that history, reflect on analytical and econometric modelling and then combine a sample of Dutch migrants in New Zealand with a representative sample of Dutch in The Netherlands to estimate wage equations and the determinants of the migration decision. We use the results for ex post evaluation of the migration decision.Joop Hartog is Fellow of IZA (Bonn), CESifo (München), AIAS and Tinbergen Institute (Amsterdam). Work on this project was begun when Hartog was Erskine Visitor at the University of Canterbury, Christchurch New Zealand. Rainer Winkelmann is Fellow of CEPR and IZA (Bonn). This paper is produced as part of a CEPR research programme on European Migration from Economic Analysis to Policy Response, supported by a grant from the Commission of the European Communities under its Human Capital and Mobility Programme (no. ERBCHRXCT940515).It was presented at the European Society for Population Economics meetings in Bonn, June 2000.

We consider the problem of choosing a subset of a finite set of indivisible objects (public projects, facilities, laws, etc.) studied by Barberà et al. (1991). Here we assume that agents preferences are separable weak orderings. Given such a preference, objects are partitioned into three types, goods, bads, and nulls. We focus on voting rules, which rely only on this partition rather than the full information of preferences. We characterize voting rules satisfying strategy-proofness (no one can ever be better off by lying about his preference) and null-independence (the decision on each object should not be dependent on the preference of an agent for whom the object is a null). We also show that serially dictatorial rules are the only voting rules satisfying efficiency as well as the above two axioms. We show that the separable domain is the unique maximal domain over which each rule in the first characterization, satisfying a certain fairness property, is strategy-proof.

This article presents a new program of collegial supervision called ‘Collegial Introvision-Supervision’ (KIS). This phased program is based upon different concepts of collegial supervision (Pallasch, 1996; Spiess, 1996; Voss, 1996) and in particular on concepts of the TZI group supervision (Meister, 1996). The theoretical development is based on the ‘Integrative Introvision-Councelling’ and the practical foundation builds upon numerous supervision experiences of the author as well as upon tests in two projects of the professional education of teachers and social workers. A substantial aim of this new program is to find a procedure that optimises the perception of the factors taking part in the educational situation in order to make, based on that new perception, a new situational processing possible which allows a more appropriate educational reaction. The core of this change of perception is to reduce biographically caused aspects of a stress-generating estimation of the situation and to establish a calmer educational-acting mode. 相似文献

Moving Extremes Ranked Set Sampling (MERSS) is a useful modification of Ranked Set Sampling (RSS). Unlike RSS, MERSS allows
for an increase of set size without introducing too much ranking error. The method is considered parametrically under exponential
distribution. Maximum likelihood estimator (MLE), and a modified MLE are considered and their properties are studied. The
method is studied under both perfect and imperfect ranking (with error in ranking). It appears that these estimators can be
real competitors to the MLE using the usual simple random sampling (SRS). 相似文献

This paper investigates the relative small sample performance of several robust unit root tests by means of a simulation study.
It is confirmed that the traditional least-squares based Dickey-Fuller test has substantially lower power than several robust
alternatives if the error distribution is fat-tailed while its power gain is small at the normal model. Particularly good
results are achieved by a quasi-maximum likelihood test. However, all robust tests under consideration exhibit severe size
distortions if the disturbances follow a skewed distribution. Moreover, under additive outliers, robust tests fail to produce
stable sizes and good power properties. Consequently, the value of using robust unit root tests depends heavily of the type
of nonnormality at hand. 相似文献

We discuss in this paper the assessment of local influence in univariate elliptical linear regression models. This class includes
all symmetric continuous distributions, such as normal, Student-t, Pearson VII, exponential power and logistic, among others.
We derive the appropriate matrices for assessing the local influence on the parameter estimates and on predictions by considering
as influence measures the likelihood displacement and a distance based on the Pearson residual. Two examples with real data
are given for illustration. 相似文献

The results of this study support the notion that pathological gamblers drawn from the community would score higher on all three scores from the YBOCS than light gamblers. Consistent with hypotheses, pathological gamblers (lottery and scratch ticket) reported more obsessions, compulsions, and avoidance behavior than the light gamblers, and also reported having more urges to engage in injurious behaviors to themselves and others. These findings provide evidence that pathological gambling falls in a spectrum or family of disorders which have obsessive-compulsive disorder at its core. These findings support McElroy, Hudson, Philips, et al.'s (1993) suggestions of similarities between OCD and Impulse Control Disorders, and extend Blaszczynski (1999) findings of overlap between pathological gamblers and OCD in a treatment population. Heavy gamblers also reported significantly more hoarding symptoms and compulsive buying than light gamblers. More research in this area may show further evidence of a spectrum of disorders with obsessive compulsive disorder at its core, and show further links between impulse control disorders (such as pathological gambling) and OCD. 相似文献
