In this paper, the procedures and problems of the changeover to the euro are reviewed. The legal elements involved are discussed as are the psychological aspects. Various practical problems and proposed solutions are described. The possibility of resistance from the consumers in certain segments of the Member State populations is also addressed. One reason for any such resistance might be that for many citizens, the change of currency appears to have little bearing on their everyday concerns.Particular attention is devoted to the scenario for the period 1 January to 1 July 2002, during which coins and notes in euros and national monetary units can be in circulation at the same time.  相似文献

The report of the WTO Appellate Body in the shrimp-turtle case may prove to be of fundamental importance for the development of the GATT/WTO system. It asserts that a WTO member can unilaterally condition access to its market on compliance with environmental policies, as long as the regulations are administered in an even-handed manner and do not amount to disguised protectionism. Will the incidence of unilateral trade measures increase dramatically as a result of this decision?  相似文献

Using Swedish equity option data, this study investigates how well the actual exercise behavior of American put options corresponds to the early exercise rules. The optimal exercise strategy is established in two ways. First, the critical exercise price, above which a put option should be exercised early, is computed and compared to the actual exercise price. Second, the exercise value of the option is compared to its market bid price. The results show that most early exercise decisions conform to rational exercise behavior, even though a large number of failures to exercise are found. Most of the faulty exercises can also be discarded after a sensitivity analysis, although several failures to exercise are considered irrational, even after taking transaction costs into account. © 2000 John Wiley & Sons, Inc.

The mutual fund theorem (MFT) is considered in a general semimartingale financial market S with a finite time horizon T, where agents maximize expected utility of terminal wealth. The main results are:
(i)  Let N be the wealth process of the numéraire portfolio (i.e., the optimal portfolio for the log utility). If any path-independent option with maturity T written on the numéraire portfolio can be replicated by trading only in N and the risk-free asset, then the MFT holds true for general utility functions, and the numéraire portfolio may serve as mutual fund. This generalizes Merton’s classical result on Black–Merton–Scholes markets as well as the work of Chamberlain in the framework of Brownian filtrations (Chamberlain in Econometrica 56:1283–1300, 1988). Conversely, under a supplementary weak completeness assumption, we show that the validity of the MFT for general utility functions implies the replicability property for options on the numéraire portfolio described above.
(ii)  If for a given class of utility functions (i.e., investors) the MFT holds true in all complete Brownian financial markets S, then all investors use the same utility function U, which must be of HARA type. This is a result in the spirit of the classical work by Cass and Stiglitz.

This paper examines the role of the tax‐free income tax threshold in a complex tax and transfer system consisting of a range of taxes and benefits, each with its own taper rates and thresholds. Considering a tax and benefit system with benefit taper rates whereby some benefits are received by income groups other than those at the bottom of the distribution, it is suggested that a tax‐free threshold is not a necessary requirement to achieve redistribution. Four alternative policy changes, each involving the elimination of the tax‐free threshold in Australia and designed to achieve approximate revenue neutrality, were examined using the Melbourne Institute Tax and Transfer Simulator. A range of implications were examined, including labour supply responses to tax changes and the effects of policy changes on inequality and social welfare. The results demonstrate that it is possible to eliminate the tax‐free threshold under approximate overall revenue and distribution neutrality, but that it is impossible to improve labour supply incentives at the same time. In order to achieve improved incentives, either revenue or distribution neutrality has to be sacrificed.  相似文献

Exchanges in Europe are in a process of consolidation. After the failure of the proposed merger between Deutsche Börse and Euronext, these two groups are likely to become the nuclei for further mergers and co‐operation with currently independent exchanges. A decision for one of the groups entails a decision for the respective trading platform. Against that background we evaluate the attractiveness of the two dominant continental European trading systems. Though both are anonymous electronic limit order books, there are important differences in the trading protocols. We use a matched‐sample approach to compare execution costs in Euronext Paris and Xetra. We find that both quoted and effective spreads are lower in Xetra. The differences are more pronounced for less liquid stocks. When decomposing the spread we find no systematic differences in the adverse selection component. Realised spreads, on the other hand, are significantly higher in Euronext. Neither differences in the number of liquidity provision agreements nor differences in the minimum tick size or in the degree of domestic competition for order flow explain the different spread levels. We thus conclude that Xetra is the more efficient trading system.  相似文献

This paper uses data from one of the most important European stock markets and shows that, in line with predictions from theoretical market microstructure, a small number of latent factors captures most of the variation in stock specific order books. We show that these order book commonalities are much stronger than liquidity commonality across stocks. The result that bid and ask side as well as the visible and hidden parts of the order book exhibit quite specific dynamics is interpreted as evidence that open order book markets attract a heterogeneous trader population in terms of asset valuations and impatience. Quantifying the informational content of the extracted factors with respect to the evolution of the asset price, we find that the factor information shares are highest (about 10%) for less frequently traded stocks. We also show that the informational content of hidden orders is limited.

XBRL is a language based on XML for the electronic communication of business information. It is designed to improve the exchange, aggregation and analysis of corporate data requiring disclosure, through a unique tagging structure that provides interoperability. But, the proliferation of a multitude of XBRL taxonomies, based on different accounting principles, can risk the objectives of standardization, comparability and re-usability of the information that is sought with XBRL. It is therefore essential to develop global accounting standards as a unique foundation on which the XBRL taxonomies can be established, so that it becomes possible to compare the financial information originating from various countries. Along these lines, the International Financial Reporting Standards (IFRS-GP) taxonomy was created to establish a common ground for international firms and create a platform that would enhance the benefits of XBRL. This paper examines whether the IFRS-GP taxonomy, at its current state, adequately covers European companies' dissemination practices and strengthens the benefits of XBRL. Our results provide implications for the evaluation of the effectiveness of the IFRS-GP taxonomy and shed light on directions that may lead to the improvement of this taxonomy.  相似文献

We present a model of vertical contracts between manufacturers and retailers with nonlinear pricing strategies. Using home‐scan data on bottled water produced by manufacturers and sold by retail chains in France, we estimate a structural demand and supply model allowing for two‐part tariff contracts between manufacturers and retailers. Using price‐cost margins recovered from estimates of demand parameters, we select the best supply model by performing nonnested tests, and find that manufacturers use two‐part tariff contracts with resale price maintenance. We then perform counterfactual policy simulations that restrict the use of these vertical contracts and assess welfare effects under alternative scenarios.  相似文献
