WANTED: THE EDUCATION PRESIDENT ISSUE TRESPASSING BY POLITICAL CANDIDATES

The strategy of ambiguity counsels candidates for office totake up some policy positions in the territory of the opposingparty. In 1988, both presidential candidates took some positionsof that kind: George Bush with promises on jobs and education,and Michael Dukakis on defense. This article examines (1) howaware voters were of those incidents of "issue trespassing";(2) whether attention to the electoral campaign helped votersbecome more aware; and (3) the electoral payoff of the strategy.Our findings raise serious doubts that "issue trespassing" payselectoral dividends. Voters tend to rely too much on party stereotypesto notice such attempts, and attention to the campaign doeslittle to mitigate that tendency in two of the three instancesbeing examined.     

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.     

UNDER WAY AND HERE TO STAY PARTY REALIGNMENT IN THE 1980s?

In recent years, the Republican party has sharply narrowed theDemocratic edge in overall party identification. Using New YorkTimes/CBS News surveys (1980–1986) and earlier NES/CPSsurveys, this analysis probes several explanations for thatpartisan change: generational replacement, conversion, and mobilization.The findings rule out conversion, give some support to mobilization,but emphasize the historically unique surge toward the GOP amongthe young since 1980. This break with the parental partisanlegacy signals the prospect of a party realignment through generationalreplacement.     

Candidates on Television: The 1972 Electoral Debates in West Germany

This article explores the nature and effects of the campaigndebates held in the Federal Republic of Germany in 1972. Thefindings indicate that the debates were bruising personal battlesthat emphasized issues and ethics. While they did not have anydirect effects on either candidate perceptions or issue salience,there is evidence that the debates may have had some importantindirect effects on the electorate's ultimate voting choices.     

False Discovery Rate Control of Step‐Up‐Down Tests with Special Emphasis on the Asymptotically Optimal Rejection Curve

Abstract. This paper is concerned with exact control of the false discovery rate (FDR) for step‐up‐down (SUD) tests related to the asymptotically optimal rejection curve (AORC). Since the system of equations and/or constraints for critical values and FDRs is numerically extremely sensitive, existence and computation of valid solutions is a challenging problem. We derive explicit formulas for upper bounds of the FDR and show that under a well‐known monotonicity condition, control of the FDR by a step‐up procedure results in control of the FDR by a corresponding SUD procedure. Various methods for adjusting the AORC to achieve finite FDR control are investigated. Moreover, we introduce alternative FDR bounding curves and study their connection to rejection curves as well as the existence of critical values for exact FDR control with respect to the underlying FDR bounding curve. Finally, we propose an iterative method for the computation of critical values.     

THE COMBINED EFFECT OF SALARY RESTRICTIONS AND REVENUE SHARING IN SPORTS LEAGUES

Many major sports leagues are characterized by a combination of cross‐subsidization mechanisms like revenue‐sharing arrangements and payroll restrictions. Up to now, the effects of these policy tools have only been analyzed separately. This article provides a theoretical model of a team sports league and analyzes the combined effect of salary restrictions (caps and floors) and revenue sharing. It shows that the effect on club profits, player salaries, and competitive balance crucially depends on the mix of these policy tools. Moreover, the invariance proposition does not hold even under Walrasian‐conjectures if revenue sharing is combined with a salary cap or floor. (JEL L83, C72, L11)     

PLANNING AND SCHEDULING THE REPAIR SHOPS OF THE DEUTSCHE LUFTHANSA AG: A HIERARCHICAL APPROACH

To plan and schedule the repair shops for recoverable parts at Deutsche Lufthansa AC, we designed a hierarchical model consisting of two levels. The top level calculates the optimal number of parts in the system to guarantee a certain service level while minimizing the capital tied up in parts. Given this provision, the lower level schedules the repair of parts so that the service level is actually maintained. Using queuing theory, the solution gives special attention to the different hierarchical dependencies. Lufthansa has implemented the model for its repair shops of electronic parts. Their experience with the model is discussed briefly.
