MEASUREMENT,EVOLUTION, DETERMINANTS,AND CONSEQUENCES OF STATE CAPACITY: A REVIEW OF RECENT RESEARCH

There is increasing realization that state capacity is a fundamental ingredient for effective governance, and is a crucial element of long‐run economic development. This paper offers an overview of the strengths and limitations in current empirical research on the measurement of state capacity. The paper also surveys the fast emerging literature on the determinants and effects of state capacity. We argue that existing measures on governance quality used in cross‐national research can be usefully exploited to capture different aspects of state capacity, and show that post the end of the Cold War, developing economies have experienced improvements in legal, administrative and bureaucratic capacity, but the gap with advanced economies is still wide. Future research should address the short temporal coverage of available measures of state capacity, as well as providing a systematic quantitative assessment of the determinants of capacity and of its effects on development outcomes, such as health and education, which have not received sufficient scrutiny.     

The impact of pronoun choices on consumer engagement actions: Exploring top global brands' social media communications

To enhance the understanding of consumer engagement with brand content on social media, this study examines how pronoun choices affect different types of consumer engagement (e.g., likes, comments, shares) by simultaneously exploring five different pronoun types (first-person singular, first-person plural, second person, third-person singular, and third-person plural). Furthermore, this study explores how the effects of these linguistic (pronoun) choices vary across two brand classifications: characteristics (hedonic vs. utilitarian) and offerings (goods vs. services). The proposed multivariate Poisson regression model, analyzing 15,788 unique brand posts from Facebook over an 8-month period, reveals differences in engagement due to pronoun usage across brand classifications. These results offer a deeper understanding of how the way brands talk to consumers on social media platforms influences consumers' attitudes (likes), propensity to engage with the brand (comments), and willingness to share branded content with their social networks (shares) across different brand classifications.     

Modeling Jumps and Volatility of the Indian Stock Market Using High-Frequency Data

Recent advancements in technology have led to wide availability of high-frequency financial data. The aim of this paper is to study the behavior of the Indian stock market. In particular, we analyze the returns at 5 min interval from NSE using the index NIFTY and the stocks State Bank of India and Infosys. A non-parametric approach is taken to detect jumps in the return process. The analysis shows that index jumps relate very closely with the general market news and announcements while individual stock jumps are associated with company specific news. We find that volatility of the market is best captured by asymmetric power ARCH models.

     

财政结构、城乡统筹与经济发展的空间机理研究

文章在构建财政结构及城乡统筹指数基础上,从空间角度对2009年我国经济发展机理进程分析。结果表明：2009年我国31省经济发展存在明显的空间集群特性;财政支出总体表现为促进经济发展,其中非生产性支出作用较为明显,生产性支出对于经济发展的促进作用相对较弱;城乡差异在一定层度上对经济的发展起到遏制作用。另外,空间修正收敛模型显示,1994-2009年我国经济整体呈现明显收敛。

我国风力发电的环境价值分析

风能是一种可再生能源,在当前能源短缺的时代扮演了重要角色。考虑量化风力发电的环境价值,提出风电环境价值的构成,并选取相关指标,运用环境经济学相关理论对风电的环境价值进行评估。风力发电环境价值的测算是相对于常规煤电的。为了量化风力发电在减少环境污染方面的作用,先对火电厂主要污染物的排放量进行计算,然后制定各主要污染物的环境价值标准,最后以500MW火电厂为参照,计算我国风力发电的环境价值,其结果为0．1491元／（kW·h）,而我国天然气发电的环境价值仅为0．0896元／（kW·h）,相比之下,我国风力发电的环境效益相当显著。     

金融集聚的区域实践、模式构建与发展对策研究

影响区域金融集聚的因素有很多,诸如政府政策、金融产业特性、资源禀赋、信息流动、金融地理运动、实体经济等。我国的区域金融中心大都处在积累建设期,区域金融集聚发展处于起步阶段。梳理我国各城市在金融集聚发展中结合自身情况走出的不同发展路径,其中存在一些不足,在反思的基础上可对我国不同区域金融集聚提出相应的发展对策和建议。
