文章利用我国逐步推出融资融券交易的自然实验机会,运用双重差分的研究设计,考察了卖空机制对股价反映负面消息效率的影响。文章以2007-2012年的数据为样本研究发现:相对于非标的股票,融资融券标的股票在成为标的之后,其股价对市场的向下波动及时做出了调整,使得股价对市场正负向波动反应之间的不对称性显著降低,表明标的股票更加及时和充分地吸收了有关公司价值的负面信息;同时,相对于非标的股票,融资融券标的标的股票在成为标的之后,其股价暴跌风险显著降低。文章结果表明,我国股市推出融资融券交易后,卖空机制提高了市场对标的股票负面消息的定价效率。  相似文献

Using several tests for structural stability in regressions with I(1) variables and for the existence of cointegration in models with regime shifts, the empirical evidence on the existence of a structural break in the Spanish long-run demand for broad money (ALP2) is analysed.The results indicate that shifts affecting the demand for ALP2 in recent years have substantially altered its long-run properties. As to the cause of this structural break, emphasis is placed on the role played by the increasing openness of the Spanish financial system to international markets as obstacles to free capital movements have progressively disappeared.This paper represents the views of the author and should not be interpreted as reflecting those of any institution.

As on-field success is nowadays the main objective of European soccer clubs, good management needs to extract the highest sport success from the squad talent at hand. Because teams differ in their quality, performance needs to be compared with the best practice of comparable units. One remarkable source of heterogeneity across teams is the squad composition, which can produce gains from diversity together with communication costs. The paper studies the efficiency in sporting performance of soccer teams, paying attention to how the number of foreign players relates to productive inefficiency. Using data for 146 teams in the top 5 European leagues during 10 seasons, we estimate a double heteroskedastic True Random Effects Stochastic Frontier team production function. We find that (i) the number of passes, ball recoveries, and shots from the penalty area improve team efficiency, and (ii) a higher number of foreign players increase inefficiency. Our findings suggest that gains from squad diversity might be offset by communication costs.  相似文献

碳排放权交易是否实现最初的CO2减排目标需要实证检验,已有的研究未考虑政策溢出效应以及混淆政策的存在,可能导致政策干预效用的错误估计。论文基于地区能源平衡表以及水泥生产数据对CO2进行测算,并采用包含溢出效应的合成控制模型对我国6个碳排放交易试点省份的减排效用分别进行了估计,该模型放松了“非实验单元不受干预效应影响”的假定,在溢出效应以及类似政策存在的情况下仍能得到无偏的估计。为了保证估计结果的稳健性,对效用估计值进行了安慰剂、溢出权重设定以及合成权重三方面的检验,探索了各试点碳交易市场的减排效用在量以及趋势上的差异,为全国统一碳交易市场的构建提供定量的依据。  相似文献

This paper examines price and inflation convergence between three European countries (Italy, Spain and the U.K.) and a European average and, alternatively, between them and Germany from the beginning of the 80's.  For this purpose the long-run stochastic relationships on prices derived from the convergence criteria agreed in the Maastricht Treaty are analyzed. In order to do this, some recent unit root tests have been applied as well as time-varying parameters models.  The results reject the long-run convergence hypothesis in all the cases but allow us to accept the existence of catching-up with the European average and Germany in some cases depending on the nature of the prices and on the countries considered.

This paper analyzes the relationship between the change of the exchange rate and the performance of the Chinese stock market after exchange rate regime and split share structure of stock market reformed in 2005, which is important for us to understand the linkages and mechanisms between the two markets deeply. We find that the exchange rate is highly related with the stock market, and there exists long-term cointegration. The results demonstrate that in the long term, the relationship between the two variables mainly belongs to flow-oriented model; Shanghai A Share index is influenced by the exchange rate, yet Shanghai B Share index has shown less indication of long term interrelation with the exchange rate. In the short term, the relationship between the two variables mainly belongs to stock-oriented models, there are inter influence between the stock market and the exchange market. The paper further analyzes the possible influence of different sector indices to exchange rates. Finally, the paper puts forward some advices and policy suggestions.  相似文献

This paper intends to harmonize two different approaches employed in the analysis of business cycles and, in doing so, it retrieves the stylized facts of the business cycle in Europe. We start with the classical approach proposed in Burns and Mitchell (1946) of dating and analyzing the business cycle. The stylized facts retrieved are commented and compared to those obtained by Harding and Pagan (2002) for the U.S.. Two conclusions can be extracted from the results: a) though the turning points obtained for individual countries seem to cluster and would suggest the idea of a common cycle, there are relevant differences in the stylized facts characterizing the business cycle in the individual European economies under analysis; b) moreover, we find relevant differences in the business cycle stylized facts of the European countries and the U.S., mostly in terms of the duration, the amplitude of the cycle and the shape of the recovery. We then adopt the modern alternative: the Markov-switching vector autoregression (MS-VAR). The models regime probabilities provide an optimal statistical inference of the turning point of the European business cycle. For assessing the capacity of the parametric approach to generate the stylized facts of the classical cycle in Europe, the stylized facts of the original data are compared to those of simulated data. Contrary to the results reported by Harding and Pagan (2002) , we show that the MS-VAR model is a good candidate to be used as an statistical instrument to improve the understanding of the business cycle.JEL Classification: E32, F43, F47, C32We are grateful to Mike Artis, Mike Clements and Adrian Pagan for useful comments and discussions.

This article provides new evidence on both long run and short‐run determinants of trade balance for Fiji and investigates evidence of J‐curve adjustment behaviour in the aftermath of a devaluation. We adopt a partial reduced form model that models the real trade balance directly as a function of the real exchange rate and real domestic and foreign incomes. Cointegration analysis is based on a recently developed autoregressive distributed lag approach—shown to provide robust results in finite samples. The long run elasticities are also estimated using a dynamic ordinary least squares approach and the Fully Modified Ordinary Least Squares (FM‐OLS) approach. Amongst our key results we find that there is a long‐run relationship between trade balance and its determinants. There is evidence of the J‐curve pattern; growth in domestic income affects Fiji’s trade balance adversely while foreign income improves it.  相似文献

We show that estimates of the half‐life of deviations from the law of one price are biased when their precision is not taken into account when aggregating data for different types of goods. Using a comprehensive dataset with monthly price data for 124 homogeneous products across regions in Denmark over the period 1997–2010, we find a large positive aggregation bias. On average, we find that the half‐life is 8.4 months when taking the bias into account, compared with 28.7 months when applying the standard method. The heterogeneity in the estimated half‐life can be explained by price stickiness, distance between regions, and whether the good is traded or non‐traded.  相似文献

In this paper, we study the effect of housing demand subsidies on rents using discontinuities in the Finnish housing allowance system as a quasi‐experimental setting. The stepwise dependence of housing allowance on the floor area of the dwelling and on the year of construction of the building causes economically and statistically significant discontinuities in the amounts of housing allowances. However, our results show that there are no discontinuities in the rents paid by the recipients of housing allowance at these cut‐offs. Instead, differences in the amounts of housing allowance are translated roughly one‐to‐one into differences in the rent net of housing allowance.  相似文献

What causes firm‐level product innovation in developing economies? This paper answers this question by emphasizing the role of process improvements that are influential in product innovation. We construct a firm‐level innovative capability score using novel, broad‐based, but detailed data on various process improvement practices obtained from firms in Southeast Asia. We then investigate the factors that may affect innovative capability. We also estimate the effect of the innovative capability score on product innovation controlling for research and development intensity and other firm characteristics. Our empirical investigation identifies a chief executive officer (CEO)'s past experience at a foreign or large firm, and buyer pressure to adopt international standards as key determinants of innovative capability. Novel and unique findings from our examination include: (i) the impact of a CEO's past experience at a foreign or large firm on the innovative capability is larger for local enterprises and small‐ and medium‐sized enterprises; (ii) the impact of share of foreign workers in the upper managerial levels only appears to be significant in foreign firms and larger firms; and (iii) buyer pressure is a more likely contributor to innovative capability compared with capital tie‐ups with multinational enterprises or joint venture buyers that capture vertical technology transfers. Finally, our empirical results show that a firm in Southeast Asia is more likely to achieve product innovation if the firm has had a higher innovative capability.  相似文献

The paper examines the productivity levels of the largest banks operating in the Eastern European countries over the period of the ongoing European financial crisis. Specifically, the analysis covers the periods of U.S. subprime crisis, the global financial crisis and the sovereign debt crisis. By adopting a fully nonparametric framework, it provides a probabilistic version of a directional input-oriented Malmquist productivity index alongside with its main decomposition. The results from the analysis suggest that banks have faced a deterioration of their productivity levels between the examined periods. It is evident that during the initiation of European sovereign debt crisis, the banks have weakened their ability to utilize efficiently their inputs of production and their ability to realize scale economies.  相似文献

This article examines the link between a nominal exchange rate and macrofundamentals in Central and Eastern European (CEE) countries. We use the model based on the monetary policy rule as a theoretical framework that explains the relations between the exchange rate and price level, risk premium, output gap, and expected inflation. It allows for endogeneity of the monetary policy – the issue ignored in the widely used monetary model. The sample covers the period January 2000 – December 2014, so the data are not plagued by high-inflation differentials characteristic for the early transition period and include countries with relatively flexible exchange rates. Our empirical strategy employs the panel error correction model that allows for cross-sectional dependence and a series of panel causality tests. The main finding is that the nominal exchange rates in CEE countries are not disconnected from macrofundamentals implied by the Taylor rule-based model. More specifically, we find that there is a strong cross-sectional dependence among CEE countries, exchange rates Granger-cause macrofundamentals and tend to revert to the long-run relation, and that the results are robust to the ‘extraordinary circumstances’ argument, i.e. do not rest on the dynamics during the global financial crisis.  相似文献

我国初次分配中的两极分化及成因   总被引:24,自引:1,他引:23  
本文基于我国1978—2002年间居民在初次分配中的要素所得,采用核密度函数估计各省区的收入分布,加总得到全国的收入分布,进而考察我国初次分配中的收入分布演进。主要发现是,我国收入分布不断向右平移,逐渐呈现双峰分布,这直观地刻画了我国要素收入快速增长以及在初次分配中就呈现两极分化的现状;两极分化主要是由劳动贡献这个分配标准在产业间的差异造成的,要素贡献的其他差异对我国收入分布的扭曲程度为2%—15%。这些发现意味着,缓解、消除两极分化在于校正、消除经济体现有的一些扭曲及其对收入分配标准的影响,健全现行收入分配制度的运行环境。  相似文献

The energy-GDP nexus: Evidence from a panel of Pacific Island countries   总被引:2,自引:0,他引:2  
The Pacific Island countries are small island economies that are increasingly dependent on energy for growth and development, yet highly susceptible to climate change. Thus, the relationship between energy consumption and GDP is crucial for realizing their future development and growth objectives. This article tests for Granger causality and provides long-run structural estimates for the relationship between energy consumption, GDP and urbanization for a panel of Pacific Island countries. For the panel as a whole in the long-run there is bidirectional Granger causality between energy consumption and GDP and these variables exert a positive impact on each other. A 1% increase in energy consumption increases GDP by 0.11%, while a 1% increase in GDP increases energy consumption by 0.23%. The findings suggest that for the panel as a whole these countries should increase investment in energy infrastructure and regulatory reform of energy infrastructure to improve delivery efficiency, continue to promote alternative energy sources and put in place energy conservation policies to reduce unnecessary wastage. These strategies seek to realize the dual objectives of reducing the adverse effects of energy use on the environment, while avoiding the negative effect on economic growth of reducing energy consumption.  相似文献

This paper examines the impact of outward FDI on domestic output and total factor productivity by applying cointegration techniques to macroeconomic time series data for Germany. We find a positive relationship between outward FDI and domestic output as well as between outward FDI and total factor productivity. Furthermore, our results indicate that there is bidirectional causality between outward FDI and domestic output, and outward FDI and total factor productivity, suggesting that increased output and productivity are both a consequence and a cause of increased outward FDI. Overall, the results of this paper can be interpreted as evidence of productivity-enhancing, and thus growth-enhancing, effects of outward FDI, which is inconsistent with the simplistic idea that outward investment represents a diversion of domestic economic activity.  相似文献
