We show how technological flexibility choices and equilibrium configurations (both simultaneous and sequential duopoly) depend on six industry characteristics. Low market volatility combined with intermediate market size favors inflexible technologies; large values of either volatility or size favor flexible technologies; low or intermediate values of both favor the coexistence of flexible and inflexible technologies. The possibility of a flexibility trap exists in industries of low volatility and intermediate size. Entry prevention can sometimes be achieved by inflexible technologies or flexible technologies, depending on the industry characteristics. 相似文献

This paper describes the Flemish customer contact centre for government information (‘the Flemish Infoline’) as an example of marketing in the public sector. First it defines the term ‘customer contact centre’ and describes the objectives and main characteristics of the Flemish Infoline. It then identifies the three reasons for setting up the Flemish Infoline in 1999: the complicated Belgian institutional landscape; the unprofessional telephone traffic handling and service; and the lack of knowledge about citizens' information needs. Finally, the paper applies Kotler's 4 Ps concept to the case, and puts the relevant stages from Lees‐Marsh‐ment's political marketing orientations into one integrated scheme in order to understand the functioning of the Flemish Infoline. Based on the literature and on an in‐depth interview with the project head of the Flemish Infoline, the authors demonstrate that marketing techniques can be used in contact centres for public information, but they also illustrate some important differences from those in the forprofit sector, such as the available amount of customers' personal data, the level of call operators' skills and the degree of heterogeneity of the questions. Further research on information needs and contact centres, and providing one ‘umbrella’ contact centre for government information in Belgium are recommended.

To establish the predictive validity of ethnic identification measures, respondents in the Montreal Urban Community were surveyed
and measured on a variety of ethnic dimensions. The data was then fed to a clustering algorithm. Two-group clustering assignments
were then compared to traditional taxonomic measures. It is shown that some measures do an excellent job in classifying respondents,
while others, which are commonly used in practice, do not fare as well. 相似文献

Markets reacted strongly to the World Trade Center attacks both in Europe and in the United States. The extent of this crisis was difficult to assess at the time, underlining the need for a specific tool to measure the magnitude of financial crises. A first measure was recently proposed and applied to the foreign exchange market by Zumbach et al. (2000a,b ). Their measure relies on an analogy with geophysics; the related index of market shocks (IMS) that we propose here is also the counterpart of the Richter scale used for earthquakes. We apply this measure on the French and the American stock markets to put large market events into perspective. The crisis triggered by the September attacks was actually the worst since 1987, and the ninth worst when compared to major historical ones. 相似文献

We identify two motives, prudence and risk aversion, which give rise to precautionary behavior for a quantity- or price-setting monopolist facing demand uncertainty who has dual theoretic preferences. We also analyze a piecewise linear profit function due to a tax on profits that varies with the profit level. We show that the comparative statics of greater risk (mean-preserving spread and mean-utility preserving spread) can be totally or partially determined by the Diamond-Stiglitz and Kihlstrom-Mirman single-crossing property. For example, for a prudent risk-averse quantity-setting dual theoretic monopolist, a mean-preserving spread will have the same impact on output under uncertainty as a fall in the state of demand under certainty. Finally, we find that, in contrast to expected utility, a stochastically larger state of demand (first-order stochastic dominance) will raise output even if background risk is present. 相似文献

Today, international health law and international consumer law are developing in the same direction and with much interaction. But the developments are not uniform. As international health law takes consumer protection into account, it tends to increase the gap between a Western international law and a Third World international law, and to emphasize the negative harmonization approach towards international health protection.Another problem concerns the unification of the rules of international health law and those of international consumer law. This problem is particularly difficult to solve, as the rules of international consumer law themselves are still far from being unified.

Internationales Gesundheitsrecht und Verbraucherautonomie
Zusammenfassung Internationales Gesundheitsrecht und internationales Verbraucherrecht entwickeln sich heute in gleicher Richtung, obwohl sie anderen Quellen entspringen. Die wechselseitige Durchdringung nimmt zu, auch wenn die Enwicklung nicht einheitlich vor sich geht. Je mehr das internationale Gesundheitsrecht den Verbraucherschutz in sich aufnimmt, destomehr trennt es sich in ein Recht für entwickelte Staaten und ein solches für Dritte Welt-Länder. Ein vorwiegend negativ-abwehrender Zugang herrscht vor.Ein anderes Problem beinhaltet die Harmonisierung der Regeln des internationalen Gesundheits- und des internationalen Verbraucherrechts. Dies ist schon deshalb schwer erreichbar, weil das Verbraucherrecht selbst nicht einheitlich vorgeht. Die Probleme verschärfen sich, wenn man — ohne eine internationale Verbraucherinstitution wie die WHO — eine gemeinsame positive Gesundheitspolitik für Verbraucher erreichen will.

Noisy chaotic dynamics in commodity markets 总被引:2,自引:1,他引:2

The nonlinear testing and modeling of economic and financial time series has increased substantially in recent years, enabling us to better understand market and price behavior, risk and the formation of expectations. Such tests have also been applied to commodity market behavior, providing evidence of heteroskedasticity, chaos, long memory, cyclicity, etc. The present evaluation of futures price behavior confirms that the resulting price movements can be random, suggesting noisy chaotic behavior. Prices could thus follow a mean process that is dynamic chaotic, coupled with a variance that follows a GARCH process. Our conclusion is that models of this type could be constructed to assist in forecasting prices in the short run but not over long run time periods.First version received: June 2001/Final version received: March 2003 相似文献

Summary We consider a simple model of incomplete information in location theory. Two firms compete in a two stage framework: a sequential location stage and a price competition stage. Firm 1 knows both its own constant marginal cost technology and that of Firm 2, whereas the latter has incomplete information about firm 1's technology. The location stage turns out to be a monotonic signaling game and theunique D1 equilibrium is a pure strategy separating equilibrium if firm 1's cost advantage is below some bound, and otherwise a pooling equilibrium if the prior probability that Firm 1 is of the low cost type is high, or a semi-pooling equilibrium if it is low. This surprising result is due to the fact that the location gap between the two types of Firm 1 is bounded because of natural economic reasons, which may prevent the separation of the two types. Hence, incomplete information matters: the equilibrium locations differ quite significantly from the full information equilibrium locations.We would like to thank an anonymous referee for very helpful comments and also the participants in seminars at GREQE (Marseille), Université de Montréal, UBC, HEC (Paris), in the Location Theory session of the World Congress of the Econometric Society (Barcelona) and in the Game Theory Conference at the University of Western Ontario for their comments. We remain, of course, solely responsible for the content of the paper. Financial support from FCAR (Québec), SSHRCC (Canada) and CNRS (France) is gratefully acknowledged. 相似文献

Some recent studies have benefited from advances in time series econometrics in order to evaluate price transmission mechanisms along the marketing chain. Due to the length of time series, structural changes may affect the evaluation of price–cost margins. In the case of the fresh salmon trade between Norway and France, the gross margin between producers and retailers has changed in level between January 1988 and December 1999. This article accurately identifies the date of a structural change using a range of recent ADF testing procedures (Gregory–Hansen tests, forward and backward recursive tests), before looking for the causes of the change through a survey. Two major factors can be identified: the product form and the marketing channel. Interestingly, both the increasing level of processing and the development of supermarket chains have resulted in a new role for the intermediaries, shifting from mere commercial intermediation to sub‐contracting for the big retailers. 相似文献
