破解“特里芬难题”与改革现行国际货币体系

该文从剖析“特里芬难题”的本质原因入手,提出加快国际货币体系改革是解决“特里芬难题”,更是应对近半个多世纪以来国际货币金融危机频仍的根本途径。SDR作为一种在国际货币基金组织框架下由成员国集体创设的储备资产和记账单位,未来可以考虑围绕其基本的货币要素分步开展国际货币体系的改革。随着中国经济的稳健发展和人民币跨境结算进程的加快,人民币应当在国际货币体系改革进程中发挥更大的作用。     

Social networks and managerial rent-seeking: Evidence from executive trading profitability

This study examines whether board social networks are associated with executive trading profitability. Using a sample of US public firms with a history of executive trading from years 2000 to 2015, we find robust evidence that the profitability of executive trading is significantly lower in firms with higher levels of board social networks. The evidence is consistent with our view that board social networks effectively curb executives' private information advantage over outsiders, thus leading to a lower level of managerial rent-seeking. Our research has policy implications for regulators concerned about the role of corporate board in capital markets.     

The announcement impact of seasoned equity offerings on bondholder wealth

Previous studies document a negative return to equity on the announcement of an SEO. However, the effects of SEO announcements on bonds have received little attention. We find that bondholders experience a significant positive return on the announcement of an SEO and this effect is more pronounced for bonds with lower ratings. We examine alternate explanations for bond market reactions to SEO announcements including the leverage risk reduction, wealth transfer, and information signaling hypotheses. Overall, our results are most consistent with the leverage risk reduction hypothesis.     

INFORMED TRADING RISK AND BID-ASK SPREAD CHANGES AROUND OPEN MARKET STOCK REPURCHASES IN THE NASDAQ MARKET

Microstructure theory contends that dealers' bid-ask spreads should vary intertemporally with changes in the asymmetric information component of the spread. Corporate theory suggests that stock repurchase announcements signal management's private information to the securities markets. An examination of dealers' spread behavior around firms' open market repurchases in the NASDAQ market reveals a decline in spreads adjusted for dealers' inventory-holding and order-processing costs. This decline is attributed to a reduction in informed trading risk associated with the open market repurchase announcements.     

Inflation-induced adaptive behavior

Periods of rapidly rising prices are seen by many as cyclical and pervasive phenomena in modern day economic systems. When rapid price increases occur, they are likely to induce adaptive behavior on the part of consumers. This article reports on a study seeking to analyze consumer inflation-induced adaptive behavior as it relates to three food-related consumer activities–food buying, preparation, and consumption. Results indicate that consumers, in general, attempt to adjust to the changing economic environment in several ways: they exercise more care and planning in food shopping, are more price sensitive and price conscious, are willing to sacrifice convenience but not quality, and try to maintain their usual level of food consumption and food habits. Results also indicate that inflation leads to greater adaptive behavior on the part of lower income consumers.     

Remarks on the strong law of large numbers for a triangular array of associated random variables

A strong law of large numbers for a triangular array of strictly stationary associated random variables is proved. It is used to derive the pointwise strong consistency of kernel type density estimator of the one-dimensional marginal density function of a strictly stationary sequence of associated random variables, and to obtain an improved version of a result by Van Ryzin (1969) on the strong consistency of density estimator for a sequence of independent and identically distributed random variables.     

论税务机关的首要任务是提供纳税服务

本文从宪法对纳税人的基本要求、公共行政理论与建立服务型政府的目标、西方的税收理论和实践、为纳税人服务体系的基础地位、中国税收征管的实际情况等角度进行分析和论证,认为纳税服务应该是税务机关的首要任务。     

保额及费率的异常变化对财产保险经营的影响

近年来，随着市场竞争态势的加剧，我国财产保险市场保额和费率呈现异常变动态势，再保险公司的稳健经营、保险市场的竞争秩序、政府的监督管理及消费者利益的维护带来一系列负面影响。为改变这种状况，从宏观上政府监管机构应强化监管，行业协会应发挥好引导、协调、监督作用。大力加强全社会诚信体系建设；从微观层面上保险公司应加强内控管理、强化风险意识、削减经营成本、培育创新能力，建立一套完整的费率实施和管理体系。     

REGULARITIES IN TOKYO STOCK EXCHANGE SECURITY RETURNS: P/E,SIZE, AND SEASONAL INFLUENCES

Regularities in risk-adjusted returns for securities listed on the Tokyo Stock Exchange (TSE) are examined in this study. A significant price-to-earnings (P/E) ratio effect is documented for the first time for a non-U.S. market, the TSE. Significant interactions between the P/E effect and the previously documented size and seasonal effects for the TSE are also documented. These results imply that studies of TSE companies must account for these return regularities and that explanations for such effects observed for U.S. and other markets that are based on some unique aspect of these markets are likely to be inadequate.     

A large deviation result for the difference in sample medians

Let X_m and Y_n denote the medians of independent samples from continuous populations F and G respectively. In Theorem 1 of this note, a large deviation result for the difference d_mn= X_m- Y_n is established under the assumption that F and G arc symmetric about 0. The result is then used to define a sequential rule based on medians for selecting the best of K symmetric populations.
