Faire Formeln

The literature on fair division has experienced a renaissance recently. Novel mathematical procedures promising an envy-free, socially efficient solution to conflicts over nearly indivisible goods play a particularly prominent role. This article presents a comparative experimental evaluation of three procedures. We examine to what extent features of the subjects of the procedures influence the choice in favor of one of the three negotiation protocols and the results of the division. Our analysis of the behavior of 119 subjects shows that psychological factors only affect the procedural choice. Dominance-seeking individuals tend to opt for those procedures that promise a fairer outcome than the relatively crude divide-and-choose-mechanism. In contrast, the outcome of the bilateral negotiations is determined by the attributes of the procedures. The strong influence of psychological factors at the initial stage of the bargaining process nevertheless casts strong doubts on the practicability of the procedures, recommended by the normative strand of game-theoretic negotiation analysis. The further development of ”fair formulas” for the resolution of redistributive conflicts should not neglect that the warring parties have to agree with the philosophy of the proposed bargaining protocol.     

The charity: A values-laden institution

Although charitable endeavour has been with us for all time, charities have suffered from archaic or no legislation or regulation, and from a lack of informed accounting and audit attention. The present time is a watershed, with an unprecedented convergence of interest from accountants, auditors, lawyers, the state regulatory body, the consumer and the charities themselves.The article provides the historical, political, and legal background, and the contribution of the theologian and economist. The nature of accountability is discussed, as are issues of efficiency and effectiveness, and the incidence of fraudulent activity. Finally, the roles of the various interested parties are outlined, and the way forward in the light of the convergence is suggested. With all the pieces of the jigsaw in place the charity will be enabled, although not guaranteed, to play its full role in national and international affairs. Much will depend on how successfully the charitable sector can adjust to the changes and challenges now facing it.     

Analyzing the Efficient Execution of In‐Store Logistics Processes in Grocery Retailing—The Case of Dairy Products

In this article, we examine in‐store logistics processes for handling dairy products, from the incoming dock to the shelves of supermarkets and hypermarkets. The efficient execution of the in‐store logistics related to such fast‐moving, sensitive, and essential items is challenging and crucial for grocery retailers' sales, profits, and image. In our empirical study, we survey in‐store logistics processes in 202 grocery supermarkets and hypermarkets belonging to a major retail chain in central Europe. Using a data envelopment analysis (DEA) and simulation, we facilitate process benchmarking. In particular, we identify ways of improving in‐store logistics processes by showing the performance impacts of different managerial strategies and tactics. The DEA results indicate different efficiency levels for different store formats; the hybrid store format of the small hypermarket exhibits a comparatively worse performance in the analyzed execution of in‐store logistics processes. The process simulation analysis reveals that the strategic and tactical design of in‐store logistics processes (such as store locations/layouts, capacity management, reorder time, order period, and safety stock factors) lead to substantial service performance improvements (such as higher on‐shelf availability combined with reduced inventory obsolescence costs). The results also show marginal improvements in the performance figures when delivery delays and damage to products are reduced.
