银行信贷与股票价格动态关系研究 总被引:2,自引:0,他引:2
本文采用五变量VAR模型对我国银行信贷与股票价格之间的动态关系进行实证分析,发现股票价格的上涨会导致银行信贷的扩张,但银行信贷扩张不是股票价格上涨的原因。基于此,本文提出对银行信贷的调控要考虑股票市场的影响。在股票市场繁荣的时候应该通过增加股票供给、丰富投资产品等措施防止股市泡沫的扩大,降低市场对股价升幅的预期,同时密切关注银行信贷资金的流向,防止资金由实体经济大量流向股票市场;而在股票市场萧条的时候,放松银行信贷并不能阻止股票价格下跌,稳定股票市场的关键是增强投资者信心,改善投资者对未来股票价格的预期。 相似文献

Time-Varying Arrival Rates of Informed and Uninformed Trades 总被引:3,自引:0,他引:3

We propose a dynamic econometric microstructure model of trading,and we investigate how the dynamics of trades and trade compositioninteract with the evolution of market liquidity, market depth,and order flow. We estimate a bivariate generalized autoregressiveintensity process for the arrival rates of informed and uninformedtrades for 16 actively traded stocks over 15 years of transactiondata. Our results show that both informed and uninformed tradesare highly persistent, but that the uninformed arrival forecastsrespond negatively to past forecasts of the informed intensity.Our estimation generates daily conditional arrival rates ofinformed and uninformed trades, which we use to construct forecastsof the probability of information-based trade (PIN). These forecastsare used in turn to forecast market liquidity as measured bybid-ask spreads and the price impact of orders. We observe thatPINs vary across assets and over time, and most importantlythat they are correlated across assets. Our analysis shows thatone principal component explains much of the daily variationin PINs and that this systemic liquidity factor may be importantfor asset pricing. We also find that PINs tend to rise beforeearnings announcement days and decline afterwards. 相似文献

Employee ownership (EO) has gained increasingly significant attention from both business practitioners and policy makers in China. Through the examination of the implementation of EO by China's listed firms from 1992 to 2017 with a total of 3,396 firms and 36,559 firm‐year observations, we explored the relationship between EO implementation and firm performance. In general, we found that over time, EO firms outperform non‐EO firms in China, and the influence of EO is only different in nuanced aspects in different time periods according to the change of policies. The data from the most recent period, that is, 2014–2017, indicate that EO adopters have higher performance than matched non‐EO firms both before and after adoption, but the relative performance does not increase after adoption. We further examined the interactive effect between EO and executive stock ownership (ESO) schemes and found that the adoption of ESO weakens the positive relationship between EO and firm performance. Regarding different types of EO, we found lower performance in companies with high return rights but no control rights, and we found better performance when high return rights are combined with control rights. We suggested policy and managerial implications on the basis of the findings. 相似文献

This article examines the martingale difference hypothesis (MDH) and the random walk hypothesis (RWH) for nine conventional and nine Islamic stock indices: Asia-Pacific, Canadian, Developed Country, Emerging, European, Global, Japanese, UK, and United States. It investigates whether Islamic stock indices are more, less, or as efficient as their conventional counterparts. We test four sub-periods of bullish and bearish stock markets, together with the financial meltdown and its recovery, over the period 1997–2012. We use the Escanciano and Lobato’s (2009) automatic portmanteau test (AQ) and Deo’s (2000) test for the MDH. We also apply the automatic variance ratio test (AVR) developed by Choi (1999) and Kim (2009) for the RWH. Over the period from 1997 to 2012, we find that three conventional indices (Europe, Japan, and UK) are efficient, but that none of the Islamic indices are efficient in these markets. During the recent financial crisis, our results indicate slightly more efficiency for the Islamic indices than their conventional counterparts. Our study finds that overall the conventional indices are more efficient than their Islamic counterparts. Nevertheless, during periods of general downturns the Islamic indices have shown the same level of efficiency as their counterparts. Furthermore, it appears that during the last two sub-periods under study, the Islamic indices have moved toward efficiency, displaying the same level of efficiency as their counterparts. 相似文献

The article examines the characteristics and implications of jump tail dependence in the Chinese stock market with high-frequency data. The results indicate that jumps contribute significantly to tail dependence between individual stocks and the aggregate market. Jumps are more tail dependent than raw returns and account for an average of 17 percent of the daily tail-dependence coefficient. We also find that jump tail dependence is asymmetric and substantially stronger in the lower tail than in the upper tail. Ignoring jump tail dependence may lead to underestimation of risks and produce inaccurate conclusions about the tail neutrality of a portfolio. 相似文献

We empirically test the dependence of the Russian stock market on the world stock market and world oil prices in the period 1997:10–2012:02. We also analyze countries that can be considered to be relatively similar to Russia, e.g., Poland, the Czech Republic, and South Africa. First, we apply a rolling regression to identify periods when oil prices or stock indices in the United States and Japan were important. Surprisingly, oil prices are not significant for the Russian stock market after 2006. Second, we employ a TGARCH-BEKK model to assess the degree of correlation between the markets in question, taking into account the global market stochastic trend. Correlation between markets increased between 2000 and 2012. 相似文献

This paper examines commonality in liquidity for individual equity options trading in European markets. We use high-frequency data to construct a novel index of liquidity commonality. The approach is able to explain a substantial proportion of the liquidity variation across individual options. The explanatory power of the common liquidity factor is more pronounced during periods of higher market-wide implied volatility. The common factor's impact on individual options' liquidity depends on options' idiosyncratic characteristics. There is some evidence of systematic liquidity spillover effects across these European exchanges. 相似文献

This study examines the effect of advertising expenditure on strengthening a firm’s intangible capital and firm value by attracting the public on the firm’s visibility and then investigates the role of advertising expenditures on a banking firm’s market value, liquidity, and breadth of ownership. The empirical results find that the advertising has a significantly positive effect on banking firm’s share value, liquidity, and institutional holdings. Consequently, this study concludes that advertising benefits banking firms through increased investor perceptions of such firms. In particular, the findings provide additional support for the home bias phenomena, in which investors prefer to invest in familiar stocks. 相似文献

This article develops a jump-dependent model to capture the dependences between spot and futures returns and their jumps simultaneously, named JD model. We examine hedging performance of the presenting JD model for the futures contracts of Hong Kong, Japan, Korea, Singapore, and Taiwan. The results have shown that the JD model has better out-of-sample performance than the OLS for Korea, Singapore, and Taiwan. Since these three markets have higher jump dependence between spot and futures, we consider that jump dependence plays an important role in hedging performance. The higher jump dependence means spot and futures markets move more closely when unusual news reveals itself and thus futures could hedge the spot more effectively when extreme unusual news arrives. 相似文献
