莱斯比基《罗马的节日》音乐主题分析

《罗马的节日》是意大利作曲家莱斯比基《罗马三部曲》中题材最具特色，素材最为丰富的作品，准确了解莱斯比基在此作品中的创作特征，对教学与创作都大有裨益。通过对作品中格里高利圣咏、民间曲调和各类舞曲三类主题进行分析，可见这些主题虽各具特色，但皆非单纯为了技法而出现，而是与音乐内容，即罗马本身浓重的宗教色彩有着密切的关系，也佐证了作者有着深厚的民族主义情结。     

Corporate Philanthropic Giving,Advertising Intensity,and Industry Competition Level

This article examines whether the likelihood and amount of firm charitable giving in response to catastrophic events are related to firm advertising intensity, and whether industry competition level moderates this relationship. Using data on Chinese firms’ philanthropic response to the 2008 Sichuan earthquake, we find that firm advertising intensity is positively associated with both the probability and the amount of corporate giving. The results also indicate that this positive advertising intensity-philanthropic giving relationship is stronger in competitive industries, and firms in competitive industries are more likely to donate. This study thus provides evidence suggesting that even in the wake of catastrophic events, corporate philanthropic giving is strategic.     

Optimal speculative trade among large traders

A collection of large traders holds heterogeneous prior beliefs regarding market fundamentals. This gives them a motive to engage in speculative trade with respect to market prices. Rather than assuming a particular institution or market for speculative trade, we take a mechanism-design approach by attempting to characterize the mechanism that maximizes the traders’ gains from speculative trade, subject to the incentive constraints that result from the traders’ ability to manipulate market prices. Within a stylized market model, we show that this mechanism affects price volatility without destroying ex-post efficient allocations. We also characterize the implementability of optimal speculative trade when the traders’ prior beliefs are private information.

关于SDR计价证券市场现状的分析

文章回顾了SDR作为官方清算工具的使用情况及其在私人部门中的应用历史，分析了SDR计价证券的优缺点，指出要扩大SDR的国际储备货币职能，除了要加强各国政治经济利益协调之外，还应充分借鉴欧洲货币单位（ECU）的发展经验，扩大SDR计价证券在私人部门中的应用，提高此类证券二级市场的流动性，从而促进SDR在国际贸易和国际投资方面的使用，并发挥分散美元风险的作用。
