The debate on ratification or revision of the proposed new Consumer Credit Directive continues. The European Parliament neither rejected nor approved the Commission’s proposal at the plenary session on November 5, 2003. While the Commission insists on defending the merits of the proposal, the LAC Rapporteur Würmeling calls for a complete modification. This article is intended to serve as a navigation guide past the holes and obstacles on the winding ratification path.  相似文献

This paper investigates the impact of three different types of final resolutions of a reorganisation plan – reorganisation ratification, out-of-court settlement, and filing dismissal – on the filer's lead lending bank (LLB), on which earlier research is completely silent. Results reveal that LLBs have the largest (least) negative stock returns in response to the announcement of filing dismissal (reorganisation ratification). Moreover, this paper is the first to explore the extent to which the loan-, bank-, and borrower-level variables lead to a predictable valuation effect for the filer's LLB. In addition to contributing to the literature on bank–borrower relationships, this study proposes an innovative application by providing an empirical exposition of the receiver operating characteristic curve analysis and, thus, demonstrates the models' performance in reliability and robustness.  相似文献

The number of free trade agreements (FTA) has increased substantially since 1990 despite efforts to promote multilateral trade liberalisation. While there is evidence on the determinants of FTA formation, still little is known on the processing of trade agreements, particularly regarding the pre‐implementation duration. This paper fills the research gap by using event data on the negotiation, the signing and the implementation of trade agreements. Duration analysis is employed to examine the connection between regime types and the lengths of the negotiation and the ratification stages. The results support the claim that higher levels of democratisation are associated with shorter negotiations, while political constraints lead to delays. Moreover, the depth of an agreement matters: a higher number of WTO‐X and WTO+ provisions do not only prolong the negotiation stage, but also the subsequent ratification. Against the background of potential anticipation effects of trade agreements, these results are of interest for exporting firms that assess the timing of implementation.  相似文献

It became apparent at the UN World Climate Change Conference, which took place from September 29 to October 3 in Moscow at the invitation of the Russian government, that ratification of the Kyoto Protocol by the Russian Federation is, at the least, uncertain. This could mean that the first international climate treaty will not become legally binding. What is the economic rationale behind Russian climate policy? What would be the effect of non-ratification?  相似文献

In the spring of 1866, Congress drafted what would become theFourteenth Amendment—a promise of citizenship and civilrights for all Americans regardless of race. However, the Redeemeryears following its ratification blurred its importance, illuminatedlatent racial prejudice, and then provided for the failure ofcivil rights—not normally the makings of a success story.Yet, despite the racial issues of this nation, the FourteenthAmendment has remained a part of the Constitution—readyto serve its duty to  相似文献

At its inception it was resolved to prepare a Constitution for the International Purchasing and Supply Education and Research Association (IPSERA), and this report sets out the proposals that were presented for the approval of the membership in March 1994. As is required by a comprehensive Constitution, the main areas of importance for the efficient working of the Association are addressed. These include the name, aim, objectives, membership criteria, management issues, affiliation possibilities, the manner of conducting general meetings, financial control matters, rules of operating, dissolution contingencies and ways in which the Constitution may be altered. While subject to final ratification in 1995, the Constitution has been favourably received by the membership.  相似文献

This paper presents novel empirical evidence on key predictions of heterogeneous firm models by examining stock market reactions to the Canada–United States Free Trade Agreement of 1989 (CUSFTA). I derive testable predictions for a class of models based on Melitz (2003). Using the uncertainty surrounding CUSFTA's ratification, I show that the pattern of abnormal returns of Canadian manufacturing firms was strongly consistent with predictions related to export (U.S.) tariff reductions, but less so with predictions related to import (Canadian) tariff reductions. Lower Canadian tariffs did have an effect through the implied reduction in intermediate input tariffs, however.  相似文献

After the German Federal Constitutional Court had given its consent to the ratification of the ESM Treaty in an interim proceeding with judgment dated 12 September 2012, subject to several precautionary provisions, the court audience of the main action took place on the 11–12 June 2013. Apart from the acts approving the ESM and the fiscal treaty as well as the regulation (EU) 1176/2011, the German Constitutional Court dealt intensely with the announcement of the ECB Council dated 6 September 2012 to buy bond issues to an unlimited extent from ESM/EFSF-programme states (the so-called OMT programme). The author is the attorney in the procedure 2 BvR 1824/12 of Professor von Stein and others. The article reproduces the essential points of his opening and closing pleadings.  相似文献
