The Final Instance - Unemployment Insurance Going Private? A Study of a Future Social Security Scenario in the UK and Germany

This paper explores the scope for privatizing unemployment insurance in Britain and Germany. The research builds on two consecutive projects, undertaken in the two countries between 1996 and 2000. The studies investigated people's attitudes towards the welfare state and private insurance, and families' strategies to manage the financial risk of unemployment. About 6% of the working population of both Britain and Germany claimed to possess private unemployment insurance. A further 23% in Britain and 12% in Germany expressed an intention to acquire private unemployment insurance. Attitudes towards private unemployment insurance were influenced by perceptions of unemployment risk, household circumstances, private money management strategies, and perceptions of the welfare state and the efficiency and trustworthiness of its institutions. The risk of exclusion from insurance in the two countries, either voluntary or as a result of actuarial risk assessment, is investigated. There is at present little evidence of adverse selection, nor would an expansion of the private unemployment insurance market necessarily entail that risk. However, the study found some, albeit limited, evidence of moral hazard. Significant country-specific differences were apparent in all aspects of the study.     

The effect of product variety on purchase probability

Regarding the effect of product variety on purchase probability, there exist findings which demonstrate a positive effect of variety for small assortments and a negative effect of variety for large assortments. Despite these results, little evidence exists about the causal mechanism of this effect. We conduct a field study among German consumer electronics customers to investigate the previously proposed constructs of anticipated product utility, anticipated regret and evaluation costs. The results suggest that anticipated regret and evaluation costs play a powerful role in explaining the negative link between variety and purchase probability for high variety assortments. Anticipated product utility on the other hand serves to explain part of the positive causality for low variety assortments. The results obtained give rise to recommendations for the planning of assortments.

Cui bono? Depicting the benefits of the new municipal budgeting and accounting regime in Germany

The new budgeting and accounting regime for the public sector (Doppik), which is based on private sector accounting standards, has been the subject of numerous discussions in research and practice in Germany for the last 20 years. However, those discussions were mostly characterized by assertions, unproven statements and logical arguments. The objective of this paper is to empirically analyze the perceived benefits of a reformed municipal accrual budgeting and accounting system by using a structural equation model. Our results show that improved management capabilities are an important indirect factor, whereas efficiency, intergenerational equity, and transparency are direct determinants of benefit. The consistent implementation of the new output-/outcome-oriented management rationality and the necessity of harmonizing budget laws are revealed as prerequisites for further development.     

Analyzing event stream dynamics in two-mode networks: An exploratory analysis of private communication in a question and answer community

Information about social networks can often be collected as event stream data. However, most methods in social network analysis are defined for static network snapshots or for panel data. We propose an actor oriented Markov process framework to analyze the structural dynamics in event streams. Estimated parameters are similar to what is known from exponential random graph models or stochastic actor oriented models as implemented in SIENA. We apply the methodology on a question and answer web community and show how the relevance of different kinds of one- and two-mode network structures can be tested using a new software.     

Promotion Planning and Supply Chain Contracting in a High–Low Pricing Environment

Demand forecast errors threaten the profitability of high–low price promotion strategies. This article shows how to match demand and supply effectively by means of two‐segment demand forecasting and supply contracts. We find that demand depends on the path of past retail prices, which leads to only a limited number of reachable demand states. However, forecast errors cannot be entirely eliminated because competitive promotions entail some degree of random (i.e., last‐minute) pricing. A hedging approach can be deployed to distribute demand risk efficiently over multiple promotional campaigns and within the supply chain. A retailer that employs a portfolio of forward, option, and spot contracts can avoid both stockouts and excess inventories while achieving the first‐best solution and Pareto improvements. We provide an improved forecasting method as well as stochastic programs to solve for optimal production and purchasing policies such that the right amount of inventory is available at the right time. By connecting a stockpiling model of demand with the supply side, we derive insights on optimal risk management strategies for both manufacturers and retailers in a market environment characterized by frequent price promotions and multiple discount levels. We employ a data set of the German retail market for a key generator of store traffic—namely, diapers.     

All You Need Is Trust? An Examination of Inter‐organizational Supply Chain Projects

This study examines the antecedents of supply chain project success. We first propose and test a model that describes the role of relationship‐level factors (trust and asymmetric dependence) and project‐level factors (between‐firm communication and within‐firm commitment) in determining supply chain project success. We find that project‐level factors completely mediate the effect of trust on project success. We conclude that trust, despite being a stronger predictor compared to asymmetric dependence, is necessary but not sufficient for supply chain project success. We then proceed to further explore the role of these factors by introducing a categorical scheme that differentiates supply chain projects based on the decision rights configuration of each project. This categorization enables us to explore how relationship‐level and project‐level factors can have different impact on performance based on the characteristics of a supply chain project. The findings offer insights into how to effectively manage supply chain projects and inter‐firm alliances.     

Vehicle Procurement Policy for Humanitarian Development Programs

This article aims to identify optimal vehicle procurement policies for organizations engaged in humanitarian development programs and to derive general insights on the characteristics of these policies. Toward that end, we follow an inductive approach. First, we study the operations of the International Committee of the Red Cross (ICRC) in three representative countries: Sudan, Afghanistan, and Ethiopia. Using a linear programming (LP) model primed with field data provided by the ICRC, we calculate the optimal vehicle fleet size and compare it with the policies actually implemented. Second, drawing from results of the LP model, we develop a stylized quadratic control model and use it to characterize the general structure of the optimal policy under different demand scenarios and operational constraints. After demonstrating that the results of the control model are consistent with those of the LP model in the specific context analyzed, we discuss the optimal policies and the applicability of the former as a practical tool for strategic asset planning.     

Ein Pl?doyer f��r Coaching vor dem Karrieresprung als fest installiertes Angebot in Organisationen

The occupational transitions of executives are considered in concerns of the conceptions ??Social Support?? and ??Sense of Coherence?? by a four structured model of a transition cycle. Furthermore the importance of a coaching that recognizes the specific needs during the single phases of a professional transition is described. After all the idea of a coaching is supported, which becomes a status of a fixed installation in organizations. The executives are accompanied through the transition in order to reduce the psychological and organizational costs and finally to commit them and their team members for a long-term employment. In addition the special change from an expert to an executive is taken into consideration.
