多源程序公平气氛影响个体创造力的跨层次效应

从来源角度探讨组织公平,是对现有多维度公平理论框架的重要补充。基于动机理论中的自我决定理论,以来自20个组织55个团队的250份团队领导与成员配对问卷为样本,探索中国情境下多源程序公平气氛对个体创造力的跨层次影响及作用机理。研究结果显示:不同来源（来源于领导和来源于组织）的程序公平气氛均对个体创造力有显著正向影响;心理授权在来源于领导的程序公平气氛和来源于组织的程序公平气氛对个体创造力的跨层次影响中均发挥中介作用;权力距离在来源于组织的程序公平气氛与员工心理授权的关系间起调节作用,即权力距离越高,来源于组织的程序公平气氛对员工心理授权的影响越强。     

重庆市制造业的绿色经济增长核算：2001—2010

基于生产前沿理论的绿色经济增长核算模型,不仅将技术无效率和环境代价纳入了分析框架,而且还与“物质平衡思路”一致;该模型将绿色经济增长的源泉分解为环境约束下的技术进步、技术效率变化和资本深化3大部分.对重庆市27个制造行业的经验分析结论表明:经济增长中普遍存在着技术无效率现象,但50％以上行业的技术效率都得到了改善或维持不变;资本深化是经济增长的主要源泉,而技术进步主导的全要素生产率变动在其中的贡献相对较小;技术进步是引致全要素生产率增长的主要原因.为充分发挥重庆市制造业可持续发展潜力,后续发展中必须转变经济发展方式,在环境约束下走技术进步和技术效率改善的绿色全要素生产率增长之路.     

Place,space, and foreign direct investment into peripheral cities

Perspectives drawn from the economic geography literature are increasingly used to generate insights into locational issues in international business. In this paper, we seek to integrate these literatures further by investigating the locational determinants of foreign direct investment (FDI) into peripheral cities within an emerging economy. Peripheral cities in emerging economies are attracting a growing proportion of global FDI flows, but the international business literature lacks a framework for understanding subnational determinants of FDI, particularly into non-core locations. We draw on the core-periphery model to build and test theory on how spatial interdependencies between subnational locations impact on the distribution of FDI inflows into a large and heterogeneous country China. Our results show that whilst peripheral cities tend to have a negative effect on FDI, this effect is positively moderated by proximity to core cities. The results highlight the importance of considering interactions between place and space when investigating locational issues in international business.     

Distance and government resource allocation: from the perspective of environmental information disclosure policy change

This article investigates the relationship between environmental information and government resources and focuses on the moderate effect of distance. The results show that (1) the promulgation and implementation of the Measures for the Disclosure of Environmental Information (MDEI) can improve the level and quality of environmental information and then increase resource allocation and (2), after the MDEI are issued, distance has a significant negative moderate effect on the positive impact of MDEI, and the negative moderate effect of distance is more significant in low GDP and marketization regions, high-polluting industries and firms audited by the non-Big 4 accounting firms.     

科技人才集聚对中国区域科技创新效率的影响

基于2005-2015年省际面板数据,构建超越对数随机前沿距离函数模型,借鉴产业区位熵思想,研究科技人才集聚对中国区域科技创新效率的影响。结果表明,科技创新效率存在区域差异,东部地区高于中部、西部、东北地区,西部最低;科技人才集聚规模和均衡度与区域科技创新效率显著正相关,强度与区域科技创新效率显著负相关。鉴于此,为提高区域科技创新效率、缩小区域差异,我国政府应全方位培育并吸引科技人才,合理引导科技人才流动、整合科技人才资源。     

From Returns to Tweets and Back: An Investigation of the Stocks in the Dow Jones Industrial Average

A sizeable percentage of investors are using social media to obtain information about companies (Cogent Research [2008]). As a consequence, social media content about firms may have an impact on stock prices (Hachman [2011]). Various studies utilize social media content to forecast stock market-related factors such as returns, volatility, or trading volume. The objective of this article is to investigate whether a bidirectional intraday relationship between stock returns and volatility and tweets exists. The study analyzed 150,180 minute-by-minute stock price and tweet data for the 30 stocks in the Dow Jones Industrial Average over a random 13-day interval from June 2 to June 18, 2014 using a BEKK-MVGARCH methodology. Findings indicate that 87% of stock returns are influenced by lagged innovations of the tweets data, but there is little evidence to support that the direction is reciprocal, with only 7% of tweets being influenced by lagged innovations of the stock returns. Results further show that the lagged innovations from 40 percent of stock returns affect the current conditional volatility of the tweets, while 73 percent of tweets affect the current conditional volatility of stock returns. Moreover, there is strong evidence to suggest that the volatility originating from the returns to the tweets persists for 33 percent of stocks; the volatility originating from the tweets to the returns persists for 73 percent of stocks. Last, 53 percent of stocks exhibit both immediate and persistent impacts from returns to tweets, while 90 percent of stocks exhibit both immediate and persistent impacts from tweets to returns. These results may help traders achieve superior returns by buying and selling individual stocks or options. Also, asset and mutual fund managers may benefit by developing a social media strategy.     

文化距离和国际直接投资流向：S型曲线假说

文化距离和国际直接投资流向的关系一直是学术界研究的热点问题,并且存在着“文化距离悖论”。本文在文化距离所产生的“外来者劣势”和“外来者收益”的基础上建立了新的理论框架,以此来分析文化距离和国际直接投资流向之间的复杂非线性关系。1993-2006年49个世界重要经济体在29个OECD成员国的国际直接投资数据表明,文化距离和国际直接投资流向之间存在着水平S型曲线关系。这一研究结果能够较好地解释文化距离和国际直接投资流向之间的“文化距离悖论”。     

Time series momentum trading strategy and autocorrelation amplification

This paper investigates why general Moving Average (MA) trading rules are widely used by technical analysts and others. We assume general stationary processes for prices and we derive the autocorrelation function for an MA trading rule. Based on our results, we conjecture that autocorrelation amplification is one of the reasons why such trading rules are popular. Using simulated results, we show that the MA rule may be popular because it can identify price momentum and is a simple way of assessing and exploiting the price autocorrelation structure without necessarily knowing its precise structure. This paper then, provides empirical evidence of autocorrelation amplification using 15-year daily price data for 11 major international stock indices.     

The effect of foreign currency hedging on the probability of financial distress

This paper investigates the effect of foreign currency hedging with derivatives on the probability of financial distress. I use Merton’s (1974) structural default model to compute firms’ distance to default as a proxy for their probability of financial distress. Using an instrumental variables approach to control for endogenous hedging and leverage, I find that the extent of foreign currency hedging is associated with a lower probability of financial distress. Whereas previous research finds that the probability of financial distress is a determinant of a firm’s hedging policy, this paper provides direct evidence supporting the hypothesis that the extent of hedging reduces a firm’s probability of financial distress.     

Incremental and Average Control Costs in a Model of Water Quality Trading with Discrete Abatement Units

This paper answers three questions related to the discrete nature of pollution abatement: (i) does a source’s incremental control cost (as defined by the U.S. Environmental Protection Agency) necessarily exceed its average control cost, (ii) is incremental control cost a better approximation of a source’s willingness to pay for abatement credits than average control cost, and (iii) exactly how does trading in discrete and continuous abatement markets differ? We find that the answer to the first two questions are both “no”, suggesting that the U.S. Environmental Protection Agency needs to refine its reliance on incremental control cost as the sole measure upon which to assess the financial feasibility of water quality trading. In answer to the third question, we show that the outcome of bilateral trading in the presence of discrete abatement is determined by comparing the gains from trade associated with the full sequence of possible “sunk cost trading” scenarios. For the most common case where trading partners’ average control cost curves “cross,” the trading outcome with discrete abatement is inherently sensitive to the initial allocation of abatement responsibilities.
