浅析不同依据下的合理对价——以苏宁电器的股改预案为例

本文探讨了苏宁电器两类股东对价结果分歧严重的原因,归纳概括了股改中最有代表性的两种对价补偿论,在此基础上推导了不同依据下的合理对价,分别计算了苏宁电器相应的合理送股率,据此认为苏宁电器的股改方案不太合理。     

Price Rigidity and the Selection of the Exchange Rate Regime

We evaluate and qualify Friedman's, 1953, “case for flexible exchange rates” in the presence of sticky prices in a two country model. We find that a flexible regime performs indeed better when the degree of nominal price rigidity is high while a bilateral peg does better when prices are fairly flexible. This result obtains independent of whether monetary policy is activistic or not and is mostly due to the negative relationship between employment and productivity shocks when prices are relatively sluggish (Gali, 1999). A unilateral peg tends to produce the lowest level of world welfare but it sometimes represents the best monetary arrangement for the pegger. JEL Classification Numbers: E32, E52, F33, F42     

Transparency in the interbank market and the volume of bank intermediated loans

In the present paper we study the equilibrium interaction through which the interbank market is related to the public lending and borrowing market. It turns out that this interaction is affected by the transparency in the interbank market. Interbank market transparency is modeled by means of more informative signals about future interbank rates. We find that more transparency might increase or decrease the volume of bank intermediated loans in the public market. In particular, the impact of more transparency on the volume of loans depends on the curvature of the marginal cost function of the banking firm. Furthermore, we find that expected profits of the bank are higher when the interbank market is more transparent.     

Industry‐specific Exchange Rate Fluctuations,Japanese Exports and Financial Constraints: Evidence from Panel Vector Autoregressive Analysis

Using a panel vector autoregression approach and industry breakdown data for financial constraints obtained from the Bank of Japan's Tankan (Short‐Term Economic Survey of Enterprises in Japan) database, this study empirically investigates whether and how Japanese firms' financial constraints (internal and external) influence the response of Japanese sectoral exports to an exchange rate shock. Furthermore, we use the industry‐specific real effective exchange rate data developed by to allow for different movements of real effective exchange rates across industries. It is found that financial constraints have a significant influence on Japanese exports in response to exchange rate shocks. Japanese exporters with either lower internal financial constraints or external financial constraints are less affected by the yen's appreciation. In addition, if firms face high external financial constraints, only reducing the internal financial constraints cannot help them mitigate the impact of the yen's appreciation on their exports. Thus, an accommodative financial environment also plays an important role in alleviating the impact that the yen's appreciation has on Japanese exports.     

基于剩余评价期的经济评价方法研究及在长输管道中的应用

针对传统的内部收益率存在参数条件变化需要对数据进行还原调整,且历史数据缺失时无法使用,或企业管理者不注重历史收益状况的情况,提出了基于管道项目剩余评价期的内部收益率指标,并结合油气长输管道运营实际,分别构建了运营期现金流量均衡、非均衡两种情形下的评价模型,计算分析了不同剩余评价期内部收益率与全评价期基准收益率的对应关系。最后针对某管道企业的3条管道进行了实例测算,对测算结果进行分析和评价。     

Macroeconomic stabilization through monetary and fiscal policy coordination: Implications for European Monetary Union

In a two-country model, we consider the implications of monetary and fiscal policy coordination for macroeconomic stabilization. We show that the optimal regime is one of monetary and fiscal policy coordination under flexible exchange rates. In the context of the European Community, this suggests that the desire to fix exchange rates may not be costless. In addition, we show that fiscal coordination requires a relatively high degree of flexibility in fiscal policy. This result suggests that limits on the flexibility of fiscal policies, as suggested in the Delors Report, may hinder macroeconomic stabilization.     

Social protection and regional convergence in a European Monetary Union

This paper addresses convergence in social protection and GDP in a European Economic and Monetary Union. We evaluate the impact of recently proposed EC social minimum requirements on regional convergence within the EC. Subsequently, we analyze a system of differentiated social norms as a means of raising social protection in countries with lower social standards.     

我国报业集团跨媒体经营研究

报业跨媒体经营是指报业企业为了充分利用自身的资源,开发并涉足其他诸如图书、杂志、广播电视、网络等媒体市场。随着我国报业集团化进程的快速发展,报业集团跨媒体经营的步伐也在加快。跨媒体经营既可以通过单体繁殖实现,也可以通过资本运作实现,但无论哪种方式都不能理所当然地被认为,跨媒体经营是传统媒体实现可持续发展的万金油。文章利用经济学原理分析了我国报业集团跨媒体经营的动因以及目前报业集团跨媒体经营存在的问题,并提出了针对性的政策建议。     

Exchange Rate Regime and Demand for Reserves: Evidence from Kenya,Mexico and Philippines

This paper empirically investigates the demand for international reserves (and foreign exchange reserves) during fixed and floating exchange rates periods in three developing countries: Kenya, Mexico and Philippines. Based on theoretical models, three factors are identified as important for the demand of international reserves and foreign reserves: average propensity to import, volume of imports and variability of reserves. The paper employs the cointegration methodology and error correction method to investigate the relationships. Cointegration tests results indicate a reliable long-run stationary relationship between the international reserves (and foreign exchange reserves) and the stated explanatory variables across countries and sub-periods of fixed and clean float. The error correction results indicate causality from the explanatory variables to the reserves during both the short and long run. This is true during both the fixed and the floating periods.

上海股票市场动量效应研究——基于1995—2009年周收益率数据

利用1995年1月至2009年12月期间上海证券交易所所有A股股票的日收益率数据,以本周四到下周三为一个周期计算周收益率,采用重叠抽样方法,对上海股票市场的动量效应进行实证研究。结果表明:上海股票市场存在动量效应现象,但动量效应持续的期限要短于西方发达国家的股票市场;当形成期为1周、持有期为1~3周时,投资策略组合表现出显著的动量效应;当形成期大于1周、持有期超过3周时,投资策略组合开始出现收益反转现象;当持有期和形成期增大到12~26周时,投资策略组合又表现出不显著的动量效应。
