公共产品产权结构多元态势下的供给效率分析

从产权结构多元态势这一视角分析公共产品的供给效率,不同产权安排形式在公共产品供给中存在着效率条件及非效率解,树立产权结构多元态势的经济发展观是实现公共产品有效供给的最佳路径选择.     

Three‐period,two‐treatment crossover design under long‐term carryover effect

The paper describes non‐parametric approach for analysis of a three‐period, two‐treatment, four‐sequence crossover design in which test procedure for interchangeability of the treatment effects is obtained. The proposed procedure is based on a non‐parametric model, which incorporates, along with the direct treatment effects and the usual carryover effects, the long‐term carryover effects. Relevant competitors are obtained. Related asymptotic results are given. By performing simulation study, we compared the procedures with respect to type I error rate and power. Furthermore, confidence intervals for treatment differences are studied. The procedures are illustrated with a data study.     

Investor Sentiment,Trading Behavior and Informational Efficiency in Index Futures Markets

This paper shows that traders in index futures markets are positive feedback traders—they buy when prices increase and sell when prices decline. Positive feedback trading appears to be more active in periods of high investor sentiment. This finding is consistent with the notion that feedback trading is driven by expectations of noise traders. Consistent with the noise trading hypothesis, order flow in index futures markets is less informative when investors are optimistic. Transitory volatility measured at high frequencies also appears to decline in periods of bullish sentiment, suggesting that sentiment‐driven trading increases market liquidity.     

市价委托的提交策略、风险控制与实施方案

通过实证研究,本文认为相对于限价委托,市价委托方式更为常用。市场行情越不稳定,交投越活跃,投资者越倾向于采用市价委托。市价委托的主要风险在于可能引起产生股价大幅变动,本文通过价格波动与成交效率两个角度进行比较,认为最优五档成交转限价和最优五档成交并撤销方案应是在市场现有基础上推出市价委托的首选方案。     

方法、数据与全要素生产率测算差异

研究目标：检验不同方法之间TFP测算结果的“一致性”和“稳健性”,探讨测算方法和数据选取问题。研究方法：以中国2004~2012年总量分行业面板数据为例,从多个角度比较TFP测算结果,以及通过统计检验选取适用测算方法。研究发现：第一,研究的问题不同,测算方法之间“一致性”的检验结论不同;第二,在选择测算方法时,进行相关统计量检验是必要的,这有助于鉴别模型设定是否合理,缩小可选模型范围;第三,测算方法的选择,要符合数据本身的特征,基于宏观分行业面板数据,DEA是更为适用的TFP测算方法,而劳动力投入应选取全社会从业人员指标。研究创新：多种测算方法和统计检验的应用。研究价值：本文尝试构建如何选择TFP测算方法的一般框架。     

A New Approach to Measuring a Multidimensional Productivity Index: An Application for 60 Selected Countries

This study aims to develop a productivity index which takes into account the multidimensional characteristics of productivities. Our multidimensional productivity index (MPI) not only measures individual productivities of economic resources but also evaluate productivity enhancing general capacities of economy. Individual productivity indices such as labor productivity are limited because they do not consider the factors, such as the globalization of economies and the market and institutional variables, that could have profound impacts on productivity. The multidimensional Productivity Index (MPI) is measured for 60 countries including 23 OECD countries and 10 Asian countries. Our methodology employs the concept of technical efficiency that allows us to measure the extent to which institutional and market factors contribute to the economic performance. Our findings indicate that standard productivity measures such as labor productivity may overestimate the overall productivity differences across the economies.     

Central Bank Actions and Words: The Intraday Effects of FOMC Policy Communications on Individual Equity Volatility and Returns

We compare intraday impacts of the release of Federal Reserve decision announcements and of Federal Open Market Committee minutes between 2004 and 2015 on 1,997 equity return and volatility series. We find that returns are unresponsive to either news release, but conditional volatility increases for both, manifesting immediately after each information release, and persisting for 30 minutes post‐announcement. These effects are larger for decisions than for minutes. On stratifying firms by trading intensity, we find most “high trading intensity” firms respond to these announcements, while “low trading intensity” firms are less affected. Our results show that traders respond, albeit differently, to both sets of information releases.     

Differentiated regulation: the case of charities

The increasing number and influence of charities in the economy, evidence of mismanagement and the need for information for policymaking are all reasons for establishing charity regulators. Public interest and public choice theories explain charity regulation which aims to increase public trust and confidence in charities (and thus increase voluntarism and philanthropy) and to limit tax benefits to specific organisations and donors. Nevertheless, regulation is resource intensive, and growing pressure on government budgets requires efficiencies to be found. This study proposes regulation differentiated according to charities' main resource providers, to reduce costs and focus regulatory effort, and provides a feasible segmentation.     

Performance measurement in universities: ambiguities in the use of quality versus quantity in performance indicators

Performance measurement (PM) is now common in Western universities. This is also the case in Finland, where a new funding scheme was implemented to ensure that quality was included in universities’ PM. However, this paper shows that the quality indicators in use are, in practice, quantitative. The paper is based on a large survey and has implications for university PM systems in Finland and internationally.     

Efficiency in Turkish banking: post-restructuring evidence

Turkish banking sector went through a significant restructuring process in the aftermath of the country's financial crisis of 2000–2001. In this paper, we analyze the evolution of banking performance using a novel approach due to Ray [(2007). “Shadow Profit Maximization and a Measure of Overall Inefficiency.” Journal of Productivity Analysis 27, 231–236]. We derive ‘shadow unrealized profit scores’ as well as ‘shadow input–output prices’ for each year and bank in the sector from 2002 to 2011. We argue these scores operationalize the Hicksian concept of ‘monopolistic quiet life’. We provide some evidence the sector came closer to the ‘zero profit condition’ as well as displaying a closer approximation to the ‘law of one price’ over time. We show the variability of these ‘shadow prices’ essentially coincides with that of corresponding actual prices. We utilize shadow price information to show that business models and competitive choices of banks differ across ownership types with foreign banks competing on the broadest front compared to state-owned and privately owned Turkish banks.
