The Choice of Structural Model in Trade–Wages Decompositions

This paper uses a calibrated general equilibrium model to decompose observed wage changes from trade and technology shocks into portions attributable to each source. It highlights some difficulties with the numerical performance of widely used theoretical trade structures. For small economies, the Heckscher–Ohlin model reveals specialization problems unless the price changes accompanying trade shocks are small. It can also yield strikingly different decompositions of the same wage change. A differentiated-goods model removes specialization problems and accommodates large price changes, but introduces demand-side responses greatly reducing the effect of trade on wages, and performs implausibly with sector-biased technical change.     

CAPM anomalies and the pricing of equity: evidence from the Hong Kong market

Using a sample of equity stocks traded on the Hong Kong stock market, this study examines empirically the independent and joint roles of the more commonly hypothesized variables in explaining cross-sectional variation in average returns over the period from January 1980 to December 1994. Evidence indicates that beta, book leverage, earnings-price ratio and dividend yield are not priced, whereas significant book-to-market equity, market leverage (absorbed by book-to-market equity), size, and share price effects are observed. The findings should prove valuable in portfolio management and corporate financial decisions.

国债筹资对民间投资和消费的经济效应实证分析

近几年,我国政府增发大量的国债,这为政府投资筹措了大量的建设资金,那么发行国债是否会降低民间部门的投资需求和消费需求?本文根据已研究的李嘉图等价定理在我国现阶段不成立的结论,从国债作为民间部门可支配收入角度出发,分析改革开放以来国债对民间部门总需求的影响,得出国债存量和流量会在较小程度上有利于增加民间部门消费,但是国债流量对民间部门投资存在抑制效应的结论。     

关于以薪养廉有效性的探讨:基于中国的经验

腐败的原因和治理对策是学界和实践部门共同关注的议题。许多人认为,公务员报酬过低是腐败产生的重要原因之一。在新加坡和香港地区高薪养廉的启发下,许多国家包括中国在不同程度上尝试通过以薪养廉来提升政府治理的质量。公务员收入过低无法保证正常的家庭生活开支。过低的薪酬有可能损害公务员保持个人诚信的努力,引致腐败行为。公务员薪酬的提高,甚至高于社会的平均工资水平,在此背景下"以薪"是否可以"养廉"?这是重要的理论和实践问题。基于实证数据,文章认为,公务员薪酬和廉政建设有着复杂的关系,对它们的相关性存在着一些认识上的误区。过去十余年间,我国公务员薪酬水平上升较快,腐败的程度也有所加深。     

银行业综合化经营研究

首先通过回顾国内外银行综合化经营的主要文献,然后构建了银行综合化经营的理论研究框架,并进一步对美国银行业综合化经营与总收益的关系做了OLS回归、协整、脉冲响应以及方差分解分析。研究发现:综合化指标、传统业务收益增幅、银行规模、资本结构均与总收益之间存在正相关关系,且存在长期均衡的关系;脉冲响应分析结果表明:在第1-9期、第18-24期,美国银行业综合化指标对银行业总收益的冲击为正,第10-17期,对银行业总收益的冲击为负;综合化指标对美国银行业总收益的贡献率最大,其次是银行规模,然后是传统业务收益增幅,资本结构的贡献率最小。

The power of market mood — Evidence from an emerging market

This article focuses on investor behavior and, consequently, the mood in the market. By using a self-organizing network we develop a model which tries to capture the market mood and serves as an indicator of the reasonableness of selling or purchasing securities. In this sense, the final result of this model is the same as in the model-type prediction of future stock prices, with the only exception being that one is not required to know the concrete future values of the selected security. This will indirectly support the hypothesis that psychological factors are an important (if not key) market driving force.     

The Impact of Economic Education Courses on the Knowledge and Retention of Knowledge of Secondary and Primary School Teachers

Controlling for other variables, the authors of this study isolate the effect of in-service teacher-training programs on economic knowledge. The effect of lapsed time on retention is also estimated.     

The Evolution of Technical Efficiency in the Northern Ireland Manufacturing Sector, 1973–1985

This paper uses a stochastic frontier production function approach to measure technical efficiency in firms in Northern Ireland. Firm level census of production panel data were used to examine how efficiency in firms changed over the period 1973–1985. Once estimates of efficiency were made, the causes of inefficiency based on characteristics of firms were examined. The results indicate that efficiency in Northern Ireland has improved significantly over-time. The largest increases in efficiency were in indigenously owned firms. The results suggest that many Northern Ireland owned firms were 'catching-up' in terms of efficiency with foreign owned firms over the period.     

Patents and R&D expenditure effects on equity returns in pharmaceutical industry

As costs of pharmaceutical R&D soar and productivity falls, the role of research pipelines in firm valuations is changing. To date, surprisingly little work has been published on the effects of R&D pipeline performance on equity returns, while controlling for coincident factors, such as legacy patents and presence of blockbuster drugs in production. Using 1996–2013 data for nine largest pharmaceutical companies in the world, this article assesses the role of the above factors on returns to pharmaceutical companies equity. We show significant positive link between changes in the number of blockbusters on patent six months prior and returns in excess of pharmaceutical equity index. The number of patents granted by United States Patent and Trademark Office in a quarter is also a significant factor. On the other hand, we find that increases in R&D expenditure in large-cap pharmaceutical companies are viewed negatively by investors in the short term.     

Effect of Macro Factor Volatility on the Returns of Financial Sector in Southeast Asian Stock Markets

The emphasis of this study is on the practice of the Pooled Mean Group （PMG） estimators to investigate the magnitude of macroeconomic performances： Real Gross Domestic Product （RGDP）, Foreign Exchange Rate （EX）, and Deposit Interest Rate （DINT） affecting on the rate of financial sector returns in Southeast Asian Stock Markets including Stock Exchange Of Thailand （SET） index （Thailand）, the Kuala Lumpur Composite Index （KLSE） index （Malaysia）, Financial Times Share Index （FTSI） （Singapore）, Philippine Stock Exchange （PSE）, and the Jakarta Composite Index （JKSE） （Indonesia）. The Panel Autoregressive Distributed Lag （Panel ARDL） is applied to model the relations. The study applies the Levin, Lin, and Chu （LLC） test （2002） and Im, Pesaran, and Shin （IPS） test （2003） to investigates a set of time series data to examine whether the determinants and the rate of financial sector returns contain a unit root, the next step is investigated the cointegration and causality relationship of the determinants of financial sector influencing on long-run rate of returns of financial sector in Southeast Asian Stock Markets.     

The Economic Effects of North Sea Oil on the Manufacturing Sector

This paper analyses the economic effects of the oil and gas sector (energy booms) on manufacturing output in two energy producing countries: Norway and the UK. In particular, I investigate whether there is evidence of a 'Dutch disease', that is whether energy booms have had adverse effects on manufactures. In addition to energy booms, three other types of structural disturbances are identified; demand, supply and oil price shocks. The different disturbances are identified by imposing dynamic restrictions on a vector autoregressive model. Overall, there is only weak evidence of a Dutch disease in the UK, whereas manufacturing output in Norway has actually benefited from energy discoveries and higher oil prices     

社会救助的公平与效率分析

社会救助作为社会保障制度的重要组成部分,是保护公民基本生存权利的主要内容,其实施原则主要以公平优先,同时注重效率.在现实生活中,社会救助的公平和效率损失也经常是同时发生的,公平和效率的损失造成了社会救助的资源浪费,同时也对受助者不利.     

信息化背景下的服务业发展

信息技术在服务业中的广泛应用,引发了服务业领域里的一系列深刻变革。信息化不仅成为服务业发展的新动力,更为重要的是它打破了服务业原有的发展范式和产业格局,提出了不少新的课题,并对一些传统服务经济理论观点提出了挑战。本文探讨了在信息化条件下服务业内部结构、服务贸易结构、服务业布局、产业融合和服务业就业等方面凸现的新特点和新规律。     

The effects of competitors on new product launch and market expansion in the hybrid car market

This paper evaluates the effect of competitors on automakers’ new product launch and market expansion decisions in the hybrid car market. Using data from the entire history in US hybrid car market from 2000 to 2014, this paper estimates a Poisson model with endogeneous switching to account for the initial launch and the following expansion decisions. The results indicate that the presence of competing brands’ hybrid vehicle models has a net positive effect on a brand’s initial launch and expansion decisions. This suggests that demand expansion and market learning from competitors’ hybrid model launch and consumer cultivation are very important for this relatively new technology. Further, I find that the impact of competitors varies over time, vehicle origins, and classes.     

我国资本市场的国际化与B股市场的发展定位

对一国而言,资本市场国际化是资本市场开放的最高阶段,其中包括筹资的国际化、投资的国际化和交易工具与机构的国际化。发展中国家在资本市场国际化的进程中适合采用渐进式开放模式。我国B股市场属于对外开放的国际化部分,但近年来由于发展取向的不明确,使其长期处于低迷萎缩状态。我国的B股市场应定位于外币证券市场,逐步完成其国际化进程。为此,要扩大B股市场规模,充分利用外汇储蓄,设法解决股权分置问题。     

中国服务业结构变动与增长的关联分析

1991年以来我国服务业发展呈现出明显的结构变动特征。本文通过对我国服务业内部结构与服务业增长之间相关关系进行动态和静态的实证分析,得出结论认为我国四个层次服务业的合理发展次序应为三、一、二、四。我国第二、四层次服务业发展速度应低于第一层次服务业,第三层次服务业发展速度应高于第一层次服务业,目前我国第一层次服务业增长速度趋缓不利于拉动我国服务业的进一步增长。文章最后给出了结论与政策性启示。
