This analysis utilises a model of production under risk estimatedon Finnish farm-level data to measure farmers' risk attitudesin a changing policy environment. We find evidence of heterogeneousrisk preferences among farmers, as well as notable changes overtime in farmers' degree of risk aversion. This result is dueto the increase in the non-random part of farm income generatedby the policy change after Finland's European Union accession.The analysis confirms the assertion that agricultural policiesthat are decoupled from production do affect input use and cropmix through their effect on farmers' risk attitudes. 相似文献

Born internationals: Market expansion and business operation mode strategies in the digital media field 总被引:2,自引:2,他引:0
This paper examines leading Swedish and Finnish Internet consultancies operating in the digital media service field. These
are ‘born international’ firms that internationalise their business at an exceptionally rapid pace. The paper focuses on why
and to what extent the market expansion and business operation mode strategies of these companies deviate from the traditional
pattern depicted by the Scandinavian process school. The empirical data consisted of interviews with the founder and senior
management and secondary data from company and public archives. The research findings show that in fact both the international
new venture research and the Scandinavian internationalisation model appear to be valid. The former model was evidenced by
the fact that the born internationals indeed deviated from the behaviour of the traditional firms. The latter was exemplified
by the fact that the final internationalisation profile, after the withdrawals of firms from unsuccessful markets, was close
to what the Scandinavian internationalisation model would call ‘rational’ expansion. Hence, if the investigation period is
long enough to account for unsuccessful endeavours and withdrawals, we may then find empirical support for the traditional
model as well. To be reliable, the investigation period should cover at least one economic slow down. 相似文献

We develop a bioeconomic model of the northern Balticsalmon fishery that takes into account thesimultaneous harvest of wild and reared salmon. Weassess the optimal harvest allocation between thecommercial offshore, inshore, and estuary fisheries,and the recreational river fishery that sequentiallyharvest the salmon stock. We restrict the solution tospawning stocks sufficient to preserve the wildsalmon. Empirical results suggest closure of theoffshore and inshore fisheries. Optimal managementenhances the wild stock, and results in substantialeconomic gains to the fishery. Current fisheryregulation improves the performance of the fisheryover open access, but fails to utilize the fullproductive potential of the resource. 相似文献

Voting Paradoxes and MCDM 总被引:1,自引:1,他引:0
Many, if not most, problems in group decision making can be translated into MCDM problems by substituting criteria for voters. Yet, there has been very little discussion about the implications of various types of voting paradoxes to MCDM. The classic voting paradoxes, viz. Borda's and Condorcet's, have obvious implications for certain MCDM situations. The latter implies that the notion of the best alternative, given a set of criteria and information about the ordinal ranking of the alternatives on those criteria, can be essentially arbitrary. The former, in turn, demonstrates a particularly clear case of conflict between reasonable intuitions. Completely unexplored are implications of compound majority paradoxes to MCDM. The paper deals with Ostrogorski's and Anscombe's paradoxes which result from non-bisymmetry and non-associativity of the majority relation. Moreover, we shall discuss the implications of paradox of multiple elections which is a situation where the result of multiple-item election may be a policy alternative that nobody voted for. 相似文献

Pricing by hedging and no-arbitrage beyond semimartingales 总被引:1,自引:0,他引:1
We show that pricing a big class of relevant options by hedging and no-arbitrage can be extended beyond semimartingale models.
To this end we construct a subclass of self-financing portfolios that contains hedges for these options, but does not contain
arbitrage opportunities, even if the stock price process is a non-semimartingale of some special type. Moreover, we show that
the option prices depend essentially only on a path property of the stock price process, viz. on the quadratic variation.
We end the paper by giving no-arbitrage results even with stopping times for our model class.

Market orientation and brand orientation are usually modelled as distinct antecedents of business performance, and the simultaneous performance effects of these orientations are empirically under-explored. Moreover, studies of market orientation and branding tend to focus on large corporations and the views of managers rather than the views of small business entrepreneurs. Addressing these research gaps, the current study explores market orientation and brand orientation by empirically testing their simultaneous effects on the business performance of small firms. Using primary data from 328 effective responses gathered from small business entrepreneurs, the study finds that market orientation improves the financial performance of a small firm only if it is implemented through brand orientation and eventually translated into brand performance. The results further indicate that older firms benefit more than younger firms from investing in branding, while younger firms benefit from paying attention to the actions of their rivals. 相似文献

The paper puts forward a model of the Atlantic salmon fishery in the Baltic Sea that integrates the salient biological and economic characteristics of migratory fish stocks. Designed to be compatible with the framework used for actual stock assessments, the model accounts for age-structured population dynamics, the seasonal harvest and competing harvesting by commercial and recreational fishermen. It is parameterized for the Simojoki River stock. The socially optimal policy for maximizing discounted net benefits from the fishery within an uncertain environment is determined using a dynamic programming approach and numerical solution method. Our results indicate that substantial economic benefits could be realized under optimal management without compromising stock sustainability. 相似文献
