The Siting of Hazardous Waste Facilities in Federal Systems: The Political Economy of NIMBY

This paper offers a new political economy explanation for thepervasive problem of siting hazardous waste treatment facilitiesin federal system. We first show that a decentralized systemyields the first-best waste treatment capacity level and that acentralized structure gives rise to free-riding behavior amonglocal jurisdictions. In our model, each community seeks toinfluence the central government through political contributions.This leads to suboptimal levels of treatment capacity. Thecapacity is increasing in the compensation level if the marginalbenefit of treatment capacity is sufficiently large, and in thegovernment's weight on aggregate social welfare relative tolobbying activities. The centralized system can replicate thedecentralized system with a sufficiently high compensation level.Since compensation has proved difficult, a centralized systemfaces greater obstacles than a decentralized system.     

Price Competition and Advertising Signals: Signaling by Competing Senders

Can price and advertising be used by vertically differentiated duopolists to signal qualities to consumers? We show that pure price separation is impossible if the vertical differentiation is small, while adding dissipative advertising ensures the existence of separating equilibria. Two simple, but nonstandard, equilibrium refinements are introduced to deal with the multisender nature of the game, and they are shown to produce a unique separating and a unique pooling profile. Pooling results in a zero‐profit Bertrand outcome. Separation gives strictly positive duopoly profits, and dissipative advertising is used by the high‐quality firm when products are sufficiently close substitutes. Finally, compared to the complete‐information benchmark, the separating prices of both firms are distorted upwards when the degree of vertical differentiation is large, and downwards when it is small.     

ARBITRAGE BOUNDS FOR PRICES OF WEIGHTED VARIANCE SWAPS

We develop a theory of robust pricing and hedging of a weighted variance swap given market prices for a finite number of co‐maturing put options. We assume the put option prices do not admit arbitrage and deduce no‐arbitrage bounds on the weighted variance swap along with super‐ and sub‐replicating strategies that enforce them. We find that market quotes for variance swaps are surprisingly close to the model‐free lower bounds we determine. We solve the problem by transforming it into an analogous question for a European option with a convex payoff. The lower bound becomes a problem in semi‐infinite linear programming which we solve in detail. The upper bound is explicit. We work in a model‐independent and probability‐free setup. In particular, we use and extend Föllmer's pathwise stochastic calculus. Appropriate notions of arbitrage and admissibility are introduced. This allows us to establish the usual hedging relation between the variance swap and the “log contract” and similar connections for weighted variance swaps. Our results take the form of a FTAP: we show that the absence of (weak) arbitrage is equivalent to the existence of a classical model which reproduces the observed prices via risk‐neutral expectations of discounted payoffs.     

Issues in the relationship between theory and practice in management accounting

In recent decades the interest of academic researchers in the practical aspects of management accounting has waned. This editorial explores some of the reasons of this development. Over the past few decades we have witnessed the establishment of management accounting in academia as a social science. This has increased the credibility of the accounting academics. However, it has also meant that academic researchers have neglected the technical core of their discipline and its problems and issues which have a direct practical relevance. It is concluded that there is a need for academic researchers to have a stronger focus on the technical core of the subject and to harness the findings of empirical research so that they can be used to develop and support practice.     

Monetary Policy in the Greenspan Era: A Time Series Analysis of Rules vs. Discretion*

Relationships between the Federal funds rate, unemployment, inflation and the long‐term bond rate are investigated with cointegration techniques. We find a stable long‐term relationship between the Federal funds rate, unemployment and the bond rate. This relationship is interpretable as a policy target because deviations are corrected via the Federal funds rate. Deviations of the actual Federal funds rate from the estimated target give simple indications of discretionary monetary policy, and the larger deviations relate to special episodes outside the current information set. A more traditional Taylor‐type target, where inflation appears instead of the bond rate, does not seem congruent with the data.     

Adaptive planning and uncertainty resolution

The article discusses uncertainty resolution and the approaches to uncertainty in planning. Statically perceived uncertainty may be described more or less explicitly in decision making. Stating various possible outcomes and, possibly, their numerical probabilities may allow quantitative theory to be applied. However, there will be a residual of genuine uncertainty due to the limits set by the available information. By “buying” more information the decision maker can decrease the genuine uncertainty. It is also often possible to reduce uncertainty by waiting. The most effective way is to state the expectations explicitly and to let the various future states of information correspond to alternative decisions in a conditional strategy. This requires a new kind of forecast that refers to the development of information available. A less efficient mode of planning can still take into consideration the fact that revisions are expected. This is flexible planning in a wide sense.     

Stock index dynamics and derivatives pricing with stochastic interest rates

The paper analyzes the equilibrium valuation of stock index derivatives in an economy with stochastic interest rates and with a representative agent having time-additive power utility. The equilibrium short interest rate dynamics and the equilibrium term structure of interest rates are described by an affine one-factor term structure model. In equilibrium the value of the stock index is a non-trivial function of the short interest rate. The paper investigates the consequences of the induced stock index dynamics for the theoretical spreads between index forward prices and index futures prices and the consequences for the valuation of options on stock index futures.The paper was written while the author was a visiting scholar at Department of Finance, Kellogg Graduate School of Management, Northwestern University.

Farmers,Middlemen and Exporters: A Model of Market Power,Pricing and Welfare in a Vertical Supply Chain

Markets for cash‐crops in developing countries are typically characterized by a concentration of buyer power at different levels of the supply chain. For instance, small‐scale coffee farmers sell their produce to a middleman, who in turn sells the coffee onward to an exporter, often a foreign multinational, with monopsony power in the hands of the purchasers at both levels. We analyze pricing behavior and welfare with different assumptions regarding market power. In particular, we show that a more powerful exporter is likely to benefit the producers and may even lead to higher welfare for the producer country as a whole.     

Recontextualising a strategic concept within a globalising company: a case study on Carlsberg's ‘Winning Behaviours’ strategy

A corporate strategy is often formulated on the executive floor at headquarters. However, in order to make it live in an organisation, middle management and employees must be involved and make sense of it. These actors thus contribute to, participate in and enact the strategy in processes where it may take on new meanings and forms. This article investigates how ‘Winning Behaviours’, a strategic concept developed on the initiative of top management at the Carlsberg Group in order to improve global integration in the multinational organisation, was recontextualised. It draws upon interviews and observations as well as documents collected at the company headquarters in Denmark and in its subsidiaries in China and Malaysia. Here, expatriate and local managers tried to give sense to the Winning Behaviours in various ways, and employees brought their own local leadership ideals into play when they tried to make sense of the preferred behaviours and turn them into daily practices. The process of creating a new strategic concept and making it live in other sociocultural contexts was facilitated by headquarters staff in the Human Resources and Communications departments, who thus played an important role as change agents in the ‘glocal’ strategy process.     

State support to small stores: A Nordic form of consumer policy

From the early 1970s, the Governments of Finland, Norway, and Sweden have shown considerable concern for the plight of rural consumers consequent on the closure of small stores in sparsely populated areas. In each country, special commissions were established to consider the consequences of retail concentration and legislation has been introduced to provide aid to small retail business in rural areas. The paper examines the background to this legislation and compares and contrasts the measures adopted in each of the three countries. While the policies attempt to improve the viability of rural small stores, it is argued that the measures are essentially a special type of consumer policy and that not only is there a need for more research into the effectiveness of the policies, but that perhaps the measures ought to be extended somewhat, particularly to protect the interests of consumers in urban areas.

Staatliche Unterstützung des kleinen Einzelhandels: eine skandinavische Form von Verbraucherpolitik

Zusammenfassung Die Regierungen Finnlands, Norwegen und Schwedens befassen sich seit etwa zhen Jahren mit der Situation von Verbrauchern in dünn besiedelten ländlichen Gebieten, die sich durch das Verschwinden kleiner Ladengeschäfte verschlechtert. Es wurden Kommissionen zur Untersuchung der Auswirkungen der Konzentration im Einzelhandel gebildet und Gesetze zur Förderung des kleinen Einzelhandels in ländlichen Gebieten erlassen. Dieser Beitrag behandelt den Hintergrund dieser Entwicklung und vergleicht die in den drei Ländern angewendeten staatlichen Maßnahmen, die in ihrem Kern als eine spezielle Form von Verbraucherpolitik betrachtet werden.Der Hintergrund für solche Stützungsmaßnahmen ist gekennzeichnet durch strukturelle Veränderungen im Einzelhandel seit dem 2. Weltkrieg. Seit den 50er Jahren und verstärkt in den Jahren zwischen 1960 und 1973 ging die Zahl der traditionellen Gemischtwarenläden um bis zu 50% zurück. Die Konzentration hat dazu geführt, daß der Kolonialwarenhandel von drei bis vier Ladenketten bestimmt wird und viele ländliche Gemeinden gar keinen oder nur noch einen einzigen örtlichen Laden besitzen.Um dieser Entwicklung entgegenzuwirken, bieten alle drei Staaten Investitionszulagen für die Modernisierung und Vergrößerung von Ladengeschäften. Norwegen und Schweden gewährt darüber hinaus auch Zuschüsse zu den laufenden Kosten. Abbildung 1 (S. 200) gibt einen Überblick über die Unterschiede, die zwischen den drei Ländern bestehen, jeweils im Bereich der staatlichen Maßnahmen, der Voraussetzungen, an die die staatliche Unterstützung geknüpft sind, und der verwaltungstechnischen Abwicklung.Die Betrachtung der Auswirkungen der Unterstützungsprogramme ergibt, daß in Norwegen nahezu 50% der infragekommenden Geschäfte eine Unterstützung erhielten und das Ladensterben im Laufe der Jahre von jährlich etwa 650 auf jetzt etwa jährlich 300 verringert werden konnte. In Finnland wurden bis Ende 1977 109 Geschäfte unterstützt; außerdem richtete die Regierung 10 neue Läden ein und kaufte zusätzlich 113 mobile Verkaufsstellen. In Schweden bekamen in den ersten vier Jahren 97 Läden eine Unterstützung, durch die für 20 000 Verbraucher in ländlichen Gegenden und weitere 5000 Feriengäste die Möglichkeit notwendiger Einkäufe gesichert werden konnte.Der Beitrag plädiert für eine Erweiterung der bisherigen Maßnahmen, um auch die tieferen Probleme des kleinen Einzelhandels angehen zu können. Er stellt dabei die wichtige soziale und wirtschaftliche Rolle heraus, die der kleine Laden im ländlichen und im städtischen Bereich übernimmt. Insofern wird der skandinavischen Gesetzgebung Modellcharakter auch für andere moderne Volkswirtschaften zugesprochen.Der Beitrag schließt ab mit einigen Vorschlägen für künftige Forschung und stellt dabei vor allem heraus (a) die Kosten-Nutzen-Analyse der staatlichen Maßnahmen, (b) die Untersuchung der Reaktionen der Händler auf die Förderungsprogramme und der Auswirkungen auf die geförderten Geschäfte und (c) die Analyse der Einstellungen und des Verhaltens der Verbraucher gegenüber kleineren Geschäften, um zu ermitteln, ob diese Geschäfte den Ansprüchen und den Bedürfnissen der örtlichen Kundschaft tatsächlich besser entsprechen. Darüber hinaus richtet sich ein eher theoretisches Interesse auf die Eigenschaften, die eine Volkswirtschaft aufweisen sollte, wenn die Unterstützung des kleinen Einzelhandels zugleich ein erfolgreiches verbraucherpolitisches Instrument sein soll.
