The operation of some cults and the ‘deprogramming’ of cult members are both held to be suspect. An examination of the broad characteristics, motivations and backgrounds of cult members reveals links with the authoritarian justifications of their ‘rescuers‘.—Ed. 相似文献

This study analyses employers' support for the introduction of industry‐specific minimum wages as a cost‐raising strategy in order to deter market entry. Using a unique data set consisting of 800 firms in the German service sector, we show that high‐productivity employers support minimum wages. We further find some evidence that minimum wage support is higher in industries and regions with low barriers to entry. This is particularly the case in East Germany, where the perceived threat of low‐wage competition from Central and Eastern European countries is relatively high. In addition, firms paying collectively agreed wages are more strongly in favour of minimum wages. 相似文献

This paper revisits the literature on overlapping generations models in the demographic context of a continuous age distribution
and a general age schedule of mortality. We show that most of the static results known for the 3 or N age-group models can be extended to the continuous model. Some results, previously established for economies without capital,
are extended to productive economies. We also make some progress on the existence of some steady states as well as on the
dynamic properties.

The distinction between ill-structured and well-structured decision problems is extended in this paper to include the degree of familiarity that a decision maker has with the initial state of the problem, its desired state, and appropriate transformations for resolving the problem. It is shown that problem ill-structuredness may result from inadequate information regarding any of these components and that the nature of problem ill-structuredness has important implications for problem formulation and solution. A decision tree is presented which represents strategies for either reformulating primary problems of each class of ill-structuredness to a more readily solved form, or solving the problem as initially formulated. 相似文献

In an advertising strategy, it is preferable to optimize a sequence of periodic decisions, rather than optimizing each period's decision separately. Thus, a dynamic technique such as optimal control, which is used in this study, should be employed. Necessary conditions, as inferred from a parsimonious advertising model, are tested using data from the tobacco industry. Parameter estimation involves the use of non-linear regression. The estimates permit trajectories of optimal advertising expenditures and optimal market shares to be constructed for filter cigarettes. When compared with the actual trajectories, the optimizing trajectories exhibit a striking correspondence to reality. Therefore, interesting results can be obtained using a simple model, provided the optimizing method takes into account the dynamic nature of managerial decision-making and provided powerful methods for estimating model parameters are used. 相似文献

Abstract. The paper briefly investigates theoretical arguments for mismatch unemployment; it presents a vacancy-unemployment curve for Germany and investigates various reasons for outward shifts of the curve. Both variables, unemployment and vacancies, are decomposed into flows and duration to identify the underlying processes of these shifts. The analysis of the components with the help of change-duration curves shows adverse trends for unemployment and vacancies over the business cycles. Unemployment duration has increased while vacancy duration has decreased. Mismatch in the labour market can therefore hardly be blamed to have been an obstacle for economic expansion in the German economy during the 1980s. Persistently high unemployment in Germany has to be interpreted as a hysteresis process which was driven by macroeconomic policies, increasing labour supply and restructuring imbedded in the German institutional framework. 相似文献

Past research suggests that problem solving and/or decision behavior can be altered and improved by the changes in the way information is accessed and displayed. Also, researchers have found that the usefulness of different information display formats are contingent on the characteristics of the problem task. This research investigated the impact on problem solving when accessing and using information from linear and nonlinear systems. Also, the research investigated problem-solving performance of linear and nonlinear systems when applied to different combinations of problem tasks. In a laboratory setting, linear and nonlinear systems were developed to conduct this experiment. This experiment used 64 graduate business students in a two-factor repeated-measures design employing a multivariate analysis of variance to analyze the data. Repeated measures were conducted to analyze the experimental group under both linear and nonlinear treatments. The findings from the study support the notion that the nonlinear system resulted in superior problem solving and higher levels of user satisfaction than the linear system. Specifically, the nonlinear system enabled users to make faster and more accurate decisions on perceptual problem tasks than did the linear system. For analytical problem tasks, users performed faster with the nonlinear system; however, there was no significant difference in accuracy. User satisfaction was higher with the nonlinear system under both perceptual and analytical tasks. 相似文献
