In industries like telecom, postal services or energy provision, universal service obligations (uniform price and universal coverage) are often imposed on one market participant. Universal service obligations are likely to alter firms' strategic behavior in such competitive markets. In the present paper, we show that, depending on the entrant's market coverage and the degree of product differentiation, the Nash equilibrium in prices involves either pure or mixed strategies. We show that the pure strategy market sharing equilibrium, as identified by Valletti, Hoernig, and Barros (2002), defines a lower bound on the level of equilibrium prices. 相似文献

At the end of 2007 the WTO waiver granted for the non-reciprocal EU/ACP trade preferences will phase out. New economic partnership
agreements are currently under negotiation, but whether the ACP countries will be able to benefit from them depends to a large
extent on the institutional setting in those countries. The following article takes the example of the Economic Community
of West African States to examine the situation more closely. 相似文献

This paper analyses the differences between German GAAP and IFRS by quantifying the effects of the first-time adoption of IFRS of German companies in their reporting practices. Due to the IAS Regulation EC No.1606/2002, all publicly traded European companies (including those in Germany) are required to prepare their consolidated financial statements in accordance with IFRS for accounting periods beginning on or after January 1, 2005. This paper measures the effect of the transition from German GAAP to IFRS by using indices of comparability that were developed by Gray (1980). Therefore, the impact on equity and net income is quantified by examining the reconciliations of 103 German companies which had to adopt IFRS for their consolidated financial statements in 2005. On average a significant increase in stockholders' equity and in net income could be observed. The increase in stockholders' equity is primarily due to the adoption of IAS 11, IAS 16, IAS 37, IAS 38 and IFRS 3. Concerning net income, the increase especially results from the adoption of IFRS 3. 相似文献

There is considerable quarrel as to what extent the shape and malfunctioning of contemporary African states can be attributed to the colonial experience or whether the precolonial heritage must be taken into account. Generally, the correct answer is that both, precolonial forms of political organization and the imposition of the colonial state, characterize the African situation. Yet, it is possible to distinguish more specifically between the two formative influences and to gauge their particular importance. Empirically, the result of the colonial encounter was, on the one hand, a subversion of traditional concepts of legitimacy and, on the other hand, still is the fact that the development of market economies and liberal democracies remains unlikely. Theoretically, I propose to use the notion of reciprocity to describe and analyze three historical forms of power relations, namely, clientelism, colonialism and cleptocracy. By reconstructing the historicity and malleability of the concept, I try to show its usefulness and adequacy to outline basic features of societal organization. 相似文献

Conclusion In this article, we propose a consistent view on the recent oil-price history based on fundamental data and economic theory.
We sum up: After the turn of the century three major stylized shocks have hit market. First, the demand curve has shifted
fight outwards, mainly driven, as extensively reported in the media, by sustained growth in China and other Asian Countries.
Second, supply disruptions in countries with low extraction costs (Iraq and Venezuela) have shifted the supply curve to the
left. Third, we show that speculators adjust their inventories in order to take advantage of predictable price fluctuations
and play themselves a major role in the price formation. Optimal storage theory implies that aggregate inventories are negatively
related to the oil price and positively to the volatility of supply and demand shocks.
We provide evidence that the political events in the last years have increased volatility and induced the inventory curve
to shift right outwards. We analyze in a graphical framework the interaction of all these shocks and conclude that speculators
have caused the oil price to overshoot in the short run its long-run fundamental value. However, this is not at all attributable
to market failure or the harmfulness of speculators. In fact, the opposite is true. Speculators have in general a dampening
effect on the oil price. The record oil price in the very recent history is partly a consequence of speculators maintaining
or building-up inventories to cope with the supply and demand shocks to come. Hence, high prices represent a short-term toll
for future price stability.
It follows from our analysis that the oil price is expected to fall towards its long-term mean, provided that no further shocks
hit the economy and, critically, the oil supply. As we saw, this prediction is consistent with the observed prices in the
futures markets. Also in terms of future price volatility, the outlook is rather upbeat. The increased inventory levels held
by speculators will cushion the spot market against fluctuations in natural supply and demand and limit the degree to which
the currently high underlying volatility will translate into higher price volatility.

Late and multiple bidding in second price Internet auctions: Theory and evidence concerning different rules for ending an auction 总被引:5,自引:0,他引:5
In second price Internet auctions with a fixed end time, such as those on eBay, many bidders submit their bids in the closing minutes or seconds of an auction. We propose an internet auction model, in which very late bids have a positive probability of not being successfully submitted, and show that late bidding in a fixed deadline auction can occur at equilibrium in auctions both with private values and with uncertain, dependent values. Late bidding may also arise out of equilibrium, as a best reply to incremental bidding. However, the strategic advantages of late bidding are severely attenuated in auctions that apply an automatic extension rule such as auctions conducted on Amazon. Field data show that there is more late bidding on eBay than on Amazon, and this difference grows with experience. We also study the incidence of multiple bidding, and its relation to late bidding. 相似文献

We study the possible implications of incentive schemes as a tool to promote efficiency in the management of universities. In this paper, we show that by designing internal financial rules which create yardstick competition for research funds, a multi-department university may induce better teaching quality and research, as compared to the performance of independent departments. 相似文献

The Scottish extension‐sample of the British Household Panel Study (BHPS) is used to shed light on differences in job mobility patterns in England and Scotland for both men and women. Based on probit estimates of the overall mobility rate, a new decomposition technique is applied to distinguish between explained and unexplained differences. Furthermore, exploiting data on the number of job changes, a zero inflated Poisson model is estimated to provide information on possible differences in the expected number of job changes. Overall, there is evidence that suggests significant differences in mobility patterns south and north of the Borders; however, this is confined to men. Yet, whether this suffices to justify a heterogeneous regional labour market remains to be seen. 相似文献

In this paper, we investigate the degree to which productivity adjusted deviations from PPP influence the U.S. inbound FDI.
Our results show a significant negative relationship between productivity adjusted misalignments and the U.S. inbound FDI
from Germany and the United Kingdom in the short-run, and a positive relationship in the long-run. Hence, indicating that
a positive misalignment—undervalued U.S. dollar—leads to a decrease in the U.S. inbound FDI in the short-run and to an increase
in the long-run. No significant evidence is found for Japan. Interestingly, unadjusted real exchange rate changes show no
statistically significant relationship with respect to the U.S. inbound FDI.
The authors thank the reviewers for their insightful comments. 相似文献
