Abstract. This paper studies a Cournot duopoly in international trade with firms exposed to exchange rate risk. A hedging opportunity is introduced by a forward market on which one firm can trade the foreign currency. We investigate two settings: First, we assume that hedging and output decisions are taken simultaneously. It is shown that hedging is exclusively done for risk‐managing reasons as it is not possible to use hedging strategically. Second, the hedging decision is made before the output decisions. We show that hedging is not only used to manage the risk exposure but also as a strategic device.  相似文献

Fisheries management involves many stakeholders with differentopinions about how the fishery should be optimally managed.This paper presents a multi-objective bio-economic model, whichis able to incorporate the preferences of managers and otherstakeholders. The model is a weighted goal programme coveringthe Danish industrial fishery. Economic, political and biologicalconcerns are considered simultaneously and, by applying thepreference structures of different stakeholders, it shows howthe optimally managed fishery would look from the perspectiveof managers and various interest groups. Managers, in this casethe Danish Ministry of Food, Agriculture and Fisheries, areprovided with a management tool that shows the consequencesof their preferences towards the objectives, and can be comparedwith optimal solutions as perceived by other stakeholders.  相似文献

Since January 2005 the European Union has launched an EU-internal emissions trading scheme (EU ETS) for emission-intensive installations as the central pillar to comply with the Kyoto Protocol. The EU ETS will be linked to a Kyoto emissions market where greenhouse gas emission allowances of signatory Kyoto countries can be traded. In this paper we investigate the implications of Russian market power for environmental effectiveness and regional compliance costs to the Kyoto Protocol taking into account potential linkages between the Kyoto emissions market and the EU ETS. We find that Russia may have incentives to join the EU ETS as long as the latter remains relatively separated from the Kyoto international emissions market. In this case, Russia can exert monopolistic price discrimination between two separated markets thereby maximizing revenues from hot air sales. The EU will be able to substantially reduce compliance costs if it does not restrain itself to EU-internal emission regulation schemes. However, part of the gains from extra-EU emissions trading will come at the expense of environmental effectiveness as (more) hot air will be drawn in.   相似文献

Carbon abatement policies in large open economies affect both the allocation of domestic resources and international market prices. A change in international prices implies an indirect secondary burden or benefit for all trading countries. Based on simulations with a large-scale computable general equilibrium model of global trade and energy use, we show that international spillovers have important welfare implications for carbon abatement policies designed to meet exogenous emission reduction targets. We present a decomposition of the total welfare effect of carbon abatement policies into a primary domestic market effect (at constant international prices) and a secondary international spillover impact as a result of changes in international prices. This decomposition reveals the extent to which domestic abatement costs are increased or decreased as a result of the impact of carbon abatement on international prices.  相似文献

The present paper accomplishes a major step towards a reconciliation of two conflicting approaches in mathematical finance: on the one hand, the mainstream approach based on the notion of no arbitrage (Black, Merton & Scholes), and on the other hand, the consideration of non-semimartingale price processes, the archetype of which being fractional Brownian motion (Mandelbrot). Imposing (arbitrarily small) proportional transaction costs and considering logarithmic utility optimisers, we are able to show the existence of a semimartingale, frictionless shadow price process for an exponential fractional Brownian financial market.  相似文献

This paper examines the use of futures contracts to hedge residential real estate price risk. We examine whether existing futures contacts can effectively be used to offset volatility in national house prices. Little evidence of any simple systematic relation between national prices and futures prices is found. Since house prices are not easily replicated with a portfolio of existing futures contracts, a further implication is that the Chicago Mercantile’s introduction of a financial asset whose value reflects house prices will help complete the market. Nevertheless, the success of the CME’s new derivative contracts may be limited in light of state and regional house price correlations.

Immer weniger Marken gelingt es, ihre Markenidentit?t in konsistenter Weise an allen Marke-Kunden-Kontaktpunkten umzusetzen. Insbesondere „im pers?nlichen Dialog mit den Kunden”, am PoS, versagen viele Marken. Ein zur Markenidentit?t konsistentes Auftreten der Herstellermarke kann hier nur in Kooperation mit Absatzmittlern erfolgen. Dafür unerl?sslich sind Absatzmittler, die ein hohes Brand Commitment gegenüber der Herstellermarke besitzen. Der Beitrag untersucht die Bedeutung der Absatzmittler für den Erfolg von Herstellermarken. Es werden Kriterien entwickelt, an- hand derer sich prüfen l?sst, für welche Marken die Bedeutung der Absatzmittler besonders gro? ist. Darüber hinaus wird ein Modell für ein absatzmittlergerichtetes Markenmanagement in Auszügen Vorgestellt  相似文献
