ATTITUDES TOWARDS THE EURO: AN EMPIRICAL STUDY BASED ON THE GERMAN SOCIO-ECONOMIC PANEL (SOEP)

This paper investigates changing attitudes towards the euro over time in Germany using longitudinal micro-data from the German Socio Economic Panel Study. We observe that a large part of the German population was worried about the new currency both before and after its introduction. Social psychological theories provide insight into these attitudes. Concerns regarding the euro are apparently connected with problems in handling the new currency and with the press coverage of price rises. For these reasons, future EMU member states should prepare their populations better for these challenges.     

POWER APPROXIMATIONS FOR A TWO-ECHELON INVENTORY SYSTEM USING SERVICE LEVELS

We consider a two-echelon inventory system with one warehouse and several stores. The warehouse as well as the stores are controlled by periodic review (s, S) inventory policies. We study the interrelationship between the safety stocks at the warehouse and the stores. Stockouts at the warehouse will result in supply delays to the stores and cause the lead time to be stochastic. The stores may react by increasing their safety stock. However, there is a trade-off between the safety stock at the warehouse and the safety stock at the stores. We use a service level at the warehouse to quantify the effect of warehouse stockouts on the lead time to the stores. The service level at the warehouse is considered a decision variable to find the best compromise between the various safety stocks by minimizing the overall costs. Using power approximations for the (s, S) policies, we provide an iterative procedure for adjusting the lead time distribution to the stores; this can result in substantial savings, but it doesn't guarantee the overall optimality. Numerical studies are provided to test the accuracy of approximations. The effects of the different system parameters on the inventory policy give general guidelines for use of the policies.     

Functional Modelling and Classification of Longitudinal Data*

Abstract. We review and extend some statistical tools that have proved useful for analysing functional data. Functional data analysis primarily is designed for the analysis of random trajectories and infinite‐dimensional data, and there exists a need for the development of adequate statistical estimation and inference techniques. While this field is in flux, some methods have proven useful. These include warping methods, functional principal component analysis, and conditioning under Gaussian assumptions for the case of sparse data. The latter is a recent development that may provide a bridge between functional and more classical longitudinal data analysis. Besides presenting a brief review of functional principal components and functional regression, we develop some concepts for estimating functional principal component scores in the sparse situation. An extension of the so‐called generalized functional linear model to the case of sparse longitudinal predictors is proposed. This extension includes functional binary regression models for longitudinal data and is illustrated with data on primary biliary cirrhosis.     

Creating a Crisis:German Mass Media andOil Supply in 1973-74

In the winter of 1973-74, the German Federal Republic importedmore oil than in any other year before or since. Nevertheless,the mass media were warning that an energy crisis might occur.Thereupon the population became nervous andbought more crudeoil products than ever before. As a consequence, short-termdifficulties of supply from industrial producers seemed to confirmthe warnings.     

Critical values for unit root tests in seasonal time series

SUMMARY In this paper, we present tables with critical values for a variety of tests for seasonal and non-seasonal unit roots in seasonal time series. We consider (extensions of) the Hylleberg et al. and Osborn et al. test procedures. These extensions concern time series with increasing seasonal variation and time series with structural breaks in the seasonal means. For each case, we give the appropriate auxiliary test regression, the test statistics, and the corresponding critical values for a selected set of sample sizes. We also illustrate the practical use of the auxiliary regressions for quarterly new car sales in the Netherlands. Supplementary to this paper, we provide Gauss programs with which one can generate critical values for particular seasonal frequencies and sample sizes.     

CHANGE VERSUS CONTINUITY IN WEST GERMAN PUBLIC ATTITUDES ON NATIONAL SECURITY AND NUCLEAR WEAPONS IN THE EARLY 1980s

This article first describes trends of a few key data on publicopinion on national security in West Germany since 1970, andthen examines in some detail the development and structure ofpublic attitudes on NATO's double-track decision and its implementationin the early 1980s. It addresses the problems of measuring suchattitudes and interpreting relevant public opinion data in thelight of levels of public awareness and of the personal importanceof these matters for respondents. In that context, the resultsof some methodological experiments to ascertain the impact ofquestion formats and wordings on response distributions fordefense policy survey items are also presented. Generationalreplacement and partisan polarization hypotheses to accountfor the dynamics of these attitudes are compared. The main findinghere is that growing dissent among the major parties over missiledeployment has played a much greater role in realigning publicopinion than has the coming of age of a predominantly antinuclearand antidefense "successor generation."     

The Effects of “Going Private” Using Private Equity: The Newly Private Corporation and the Dimensions of Corporate Performance

The trend toward private ownership of corporations prompts a reexamination of the dimensions of corporate performance under a governance system that includes powerful owners and a reduced public presence. Using insights from corporate social responsibility and stakeholder theories and informed by agency theory, we develop a model regarding the performance implications of public corporations going private through the use of private equity. We put forth that in general going private tends to result in greater emphasis on corporate financial performance and in lesser emphasis on corporate social performance (CSP). Yet several variables, including the firm's capitalization, its post‐going‐private exit strategy, and its managerial discretion, are proposed to moderate the negative relationship between going private and CSP.

Models,methods and tools for interorganizational logistics operations

Enterprise modelling is today one of the key techniques to improve the performances of an enterprise. This paper first defines enterprise modelling techniques as compared to BPR techniques. Then the latest developments in GRAI methodology are presented. Finally, examples of industrial applications are presented for three methods: GIM (GRAI Integrated Method) for re-engineering, GIMSOFT for the choice of an ERP software package and ECOGRAI for the design and implementation of performance indicator system.     

Visitors' Views on Residental Homes

Correspondence should be addressed to Justine Schneider, Senior Lecturer, Centre for Applied Social Studies, University of Durham, 15 Old Elvet, Durham DH1 3HL, UK. Email: Justine.Schneider{at}durham.ac.uk Summary Relatives and other people who visit residential care homeshave an opportunity to formulate their own views about the qualityof care, often over a considerable period of time. They maybe experienced in providing care themselves, and many have beenthe principal carer before admission of the resident. They canbe decision makers in purchasing care, and their preferenceswill therefore influence the market. Finally, through theirfrequent attendance, they too form part of the environment ofa home. This paper reports the findings of a survey of 228 visitorsto 17 residential care homes throughout England. It shows whothe visitors were, what they did, their likes, dislikes andideas for improvements. It summarizes what aspects were mostimportant to visitors, many of whom were former carers; thishas implications for purchasers and providers of residentialcare. It closes with a methodological discussion about how thevaluable views of visitors may be tapped without encounteringreticence due to guilt or fear of retribution affecting theresident.
