In this article, we model the determinants of spread for 734 firms listed on the NYSE over the period 1 January 1998 to 31 December 2008. We propose a panel data model of the determinants of spread. There are four main messages emerging from our work. We find a statistically significant effect of volume on spread inconsistent with the work of Johnson (2008). On price, we find mixed results, consistent with the literature. On the effect of price volatility on spread, our results are completely the opposite of the cross-sectional literature but sides with the relatively recent work of Chordia et al. (2001). We allow for persistence of spread as a determinant of spread and find significant evidence of spread persistence across all 16 sectors. Finally, we examine size effects and find statistically strong evidence of size effects based on the relationship between price and spread, persistence and spread, and volatility and spread.  相似文献

Abstract

This paper studies impacts of factor endowment on international trade in a general equilibrium model in which firms choose their technologies endogenously. Although countries only differ in factor endowment ex ante, countries may also differ in their chosen technologies. If industries choose different capital-labor intensities in equilibrium, the Heckscher–Ohlin theorem, factor price equalization theorem, the Rybczynski theorem, and the Stolper–Samuelson theorem hold. If industries choose the same capital-labor intensity in equilibrium, the volume of trade is zero. None of the four theorems applies.  相似文献

采用GARCH(1,1)模型就成交量、持仓量对大豆类期货价差波动率的影响进行实证分析,结果显示:当期成交量、持仓量对大豆期货价差波动的整体影响是显著的;滞后成交量、持仓量对大豆期货价差波动的整体影响也是显著的;当成交量、持仓量同时进入条件方差方程时,它们对大豆类期货价差波动的影响整体上也是显著的。这一结论揭示了我国大豆期货市场信息传递过程,验证了我国大豆期货市场的信息非有效性,对期货市场投资者以及期货市场监管者具有一定的借鉴意义。  相似文献

股指期货的交易类型包括开仓交易、平仓交易和换手交易,不同交易类型会对成交量和持仓量产生不同影响,进而对股指期货市场质量包括流动性、波动性和有效性产生不同影响。采用一定指标测度市场流动性、波动性和有效性,以成交量和持仓量作为中间变量,研究股指期货的不同交易类型对股指期货的流动性、波动性和有效性影响的差异性,并以沪深300股指期货合约IF1201进行实证分析,得到的结论是:平仓交易对流动性的影响最强,且为正向影响;平仓交易对波动性的影响最强,且为正向影响;平仓交易对有效性的影响最强,且为负向影响。  相似文献

一国对外直接投资与国际经济合作的动力来自于一国的人均GDP与宏观金融环境(用保险密度来简化与量化),一国对外直接投资与国际经济合作的惯性来自于一国对外直接投资量与国际经济合作完成额的滞后期的值与对滞后期变量敏感度系数的大小。本文使用中国1991年至2003年的数据,对对外投资与国际经济合作的宏观动力与惯性假说做了经验检验,该组数据很好地证明了对外投资与国际经济合作的宏观动力与惯性假说。  相似文献

本文定义月度异常交易量为本月与上个月交易金额的比值,发现中国市场月度收益率与滞后一个月的异常交易量显著负相关。在控制了公司规模、账面市值比、流动性以及动量效应等指标后仍然具有显著的解释作用。进一步研究表明,在出现高异常交易量后的12个月内,换手率和特质性波动率都有大幅上升。本文认为,交易量上升代表着市场分歧程度和受关注程度的增加,在卖空约束下会使得股票价值高估,从而造成未来收益率下降。  相似文献

The FASB, PCAOB, SEC, and AICPA have all acknowledged that the accounting field needs to revisit the statement of cash flows (SCF). While the overall number of restatements has held steady over the past five years, the percentage of cash flow restatements (CFRs) has risen from 8.7% of all restatements in 2009 to 20.2% of all restatements in 2014. We examine the determinants of CFRs, investors’ differential beliefs about CFRs, and the information content of CFRs by focusing on abnormal trading volume and price reactions to CFRs. We then examine whether the guidance the SEC/AICPA published in early 2006 changed the information content of CFRs. Finally, since the proper classification within the SCF is a current regulatory issue, we examine whether classification shifting within the SCFs impacts the market. The market finds CFRs to be informative with some investor disagreement as shown by higher abnormal trading volume. We also find an incremental volume reaction to changes in operating cash flows after the SEC allowance period. While the market responds negatively to CFRs, we find that the market does not differentiate between whether classification shifting occurs or does not occur with the CFR. This study has implications for policymakers, auditors, and investors since it is one of the first to examine the capital market consequences of CFRs.  相似文献

This paper explores whether firm‐specific information events drive economically relevant positive and negative stock price changes and trading volume and, if so, the nature of such information. We find that no less than 65% of significant price changes and trading volume movements in our sample of FTSE 350 companies can be readily explained by public domain information contradicting the thesis that corporate news is not a primary driver, and that share price changes and trading volume activity are driven by factors unrelated to information flows per se. In addition, we find that a parsimonious set of news categories represent the key drivers. Sell‐side analyst stock recommendations and earnings forecast revisions as a class, unaccompanied by other news releases, dominate all other news categories in terms of significant market reaction. However, taking into account the relative magnitude of market response to different news releases, firms' formal accounting disclosures dominate within this domain. As such, we conclude these are not fully anticipated by apparently more timely market disclosures, and that the existence of news services and the activities of the sell‐side analyst are not substitutes for a firm's interim and preliminary results.  相似文献
