We examine how undesirable juvenile behavior is related to the structure and quality of home life. In homes with both own-parents or one parent and another adult partner, we distinguish among unhappy, moderately happy, and very happy relationships for the adults. Single-parents are treated as one category. Living with both own-parents in a very or moderately happy relationship is associated with reduced likelihood of most undesirable behaviors. In most cases, we cannot reject the hypothesis that the probability of juvenile undesirable behavior is the same across own-parents in ah unhappy relationship, a very or moderately happy parent and stepparent, and a single-parent. 相似文献

Why environmental and resource economists should care about non-expected utility models 总被引:1,自引:0,他引:1
Experimental and theoretical analysis has shown that the conventional expected utility (EU) and subjective expected utility (SEU) models, which are linear in probabilities, have serious limitations in certain situations. We argue here that these limitations are often highly relevant to the work that environmental and natural resource economists do. We discuss some of the experimental evidence and alternatives to the SEU. We consider the theory used, the problems studied, and the methods employed by resource economists. Finally, we highlight some recent work that has begun to use some of the alternatives to the EU and SEU frameworks and discuss areas where much future work is needed. 相似文献

N. C. G. Campbell M. T. Cunningham 《International Journal of Research in Marketing》1985,2(4):255-262
In industrial markets many managers from marketing, technical service and production functions interact with customers. How should these managers be allocated to an evolving array of customers? This paper reports on the customer visits made by the managers of one packaging supplier. The visits of the marketing people seem related to the financial significance of the customer, whereas the technical visits are best understood by a ‘portfolio’ approach. At the same time many idiosyncratic and situational factors affect resource deployments. 相似文献

The paper shows the need for improving the information support of the practice of urban planning. It provides methodological approaches to the formation of systems of urban indicators for diagnosing the situation in preparing programs, plans, taking management decisions and estimating the results of their implementation. 相似文献

Summary This paper considers the prediction of the sample mean by extreme order statistics when the population distribution is known.
The predictor and its mean square error are found. The problem is studied in details for the normal model. 相似文献

The Race to Connect East Asia: An Unending Steeplechase 总被引:2,自引:2,他引:0
T. J. PEMPEL † 《Asian Economic Policy Review》2006,1(2):239-254
East Asia has become more integrated as a region over the past quarter century. In looking ahead, this article identifies five central obstacles to further regionalism. Three address the composition of any future East Asian region: the arenas in which cooperation is sought, the geographic scope of any future region, and the extent to which regional ties are formalized. The other two variables will influence the future regardless of how the first three are resolved: the structure and balance of domestic political forces, and leadership. The complex interactions of these five are then examined in the recent moves toward preferential trade pacts, increased regional monetary and financial cooperation, and security. 相似文献

A jump diffusion model coupled with a local volatility function has been suggested by Andersen and Andreasen (2000). By generating
a set of option prices assuming a jump diffusion with known parameters, we investigate two crucial challenges intrinsic to
this type of model: calibration of parameters and hedging of jump risk. Even though the estimation problem is ill-posed, our
results suggest that the model can be calibrated with sufficient accuracy. Two different strategies are explored for hedging
jump risk: a semi-static approach and a dynamic technique. Simulation experiments indicate that each of these methods can
sharply reduce risk exposure.

Assessing the Degree of Spot Market Integration for U.S. Natural Gas: Evidence from Daily Price Data 总被引:1,自引:0,他引:1
This paper assesses the degree of market integration in the U.S. natural gas market following the FERC’s ‘open access’ reforms.
Daily spot prices at 76 market locations from 1993 to 1997 are used to examine the geographic extent of the market and the
speed with which market forces move prices toward equilibrium in the face of ongoing price shocks. The empirical results suggest
that the East and Central regions form a highly integrated market, but that this market is quite segmented from the more loosely
integrated Western market. 相似文献

Since 1920, the thrust of German law on workplace codetermination has changed on a number of occasions. We describe the latest swing of the legislative pendulum—favoring works council formation and competence—and evaluate the case for it. We provide new information on the extent of works councils before reviewing the evidence on their economic effects, focusing on some new results from matched-plant data. If the former evidence points to a codetermination deficit, this shortfall does not appear to have negative consequences for workplace productivity, profitability, and employment. 相似文献
