Abstract:   In this paper we study the quote revision behavior of NASDAQ market makers by analyzing inter‐temporal changes in their spread and depth quotes. Using individual dealer quote and trade data for a sample of 2,319 stocks, we find that NASDAQ dealers make more frequent revisions in depths than in spreads and the extent of liquidity management is greater for stocks of smaller companies, lower‐priced stocks, and stocks with larger trade sizes and fewer number of transactions. We show that intraday variation in the number of quote revisions follows the U‐shaped pattern, indicating that the extent of liquidity management is greater during the early and late hours of trading than during midday.  相似文献

We use data on Nasdaq stocks to study arguments that preferencing reduces incentives to quote competitively. We examine a market maker's volume as a function of various measures of quoting aggressiveness. We find that more aggressive quoting does indeed result in more business. We also examine the relation between volume and quote aggressiveness as a function of the competitiveness. We find that in less (more) competitive markets, increased quote aggressiveness has a smaller (larger) impact on market share. We argue that preferencing arrangements could be more harmful to public investors in markets where competition is weak.  相似文献

With the benefit of very high frequency (25 million 1 minute observations) and recent data (2001) for the UK, this paper explores a number of intra day patterns of stock market behaviour. More specifically, a distinct reverse J shaped bid‐ask spread pattern is noted for SETS securities, a declining bid‐ask spread pattern for non‐SETS securities, a two hump pattern for trading volume and a U‐shaped pattern for returns volatility for all securities. In terms of complementing the existing literature, the paper shows that differences in trading systems may affect the bid‐ask spread patterns, while differences in market environments (i.e. US and UK markets) seems to affect the trading volume pattern. The paper suggests avenues for future research, in particular, the need to consider what factors are significant in determining intra day patterns for different trading systems and the need for additional cross‐market comparisons to identify how institutional factors affect the behaviour of investors on an intra day basis.  相似文献

This paper examines intra-day variations in the bid-ask spread, volatility and volume for stocks traded on the London Stock Exchange. The data set used consists of quote and transactions data for a large sample of 835 stocks traded during the first quarter of 1991. The focus of the study is twofold; first, is to document a number of stylized facts regarding the intra-day behaviour of spread, trading volume, volatility etc. Second, the paper tests some predictions of two theoretical models of intra-day behaviour: the Admati and Pfleiderer and the Brock and Kleidon models. In addition, the paper also studies qualitatively the intra-day behaviour of several variables of interest including volume per transaction, transactions per fifteen-minute interval and spreads/trading volume for stocks of differing liquidity. The results suggest that the bid-ask spread is wide at the open, constant through the day and rises slightly at the close. Trading volume, in contrast is not highest at the open and the close. Volatility, based on the mid-point of the inside spread, shows a U-shaped pattern. Volume per transaction, in contrast, is fairly constant throughout the day. Further, the intra-day trading volume pattern differs for liquid and illiquid stocks. The results provide mixed support for current theoretical models of intra-day behaviour of spread, volume and volatility on the London Stock Exchange  相似文献

This study presents an analysis of the impact of the introduction of quotes in sixteenths of a dollar on the AMEX, Nasdaq, and NYSE in mid-1997 on select market characteristics such as spreads, effective spreads, quoted depth, and volume. The findings of the study document reductions in the bid-ask spread, effective spread, and a statistically significant increase in the number of quotes. Interestingly, we find that liquidity, as measured by the total depth at the bid and ask, declines significantly on the AMEX and NYSE, but increases on the Nasdaq. Trading volume increases on the NYSE, but remains unchanged for the AMEX and Nasdaq. We also find that the proportion of even-increment quotes is a relevant factor affecting percentage spreads for Nasdaq both before and after and for the NYSE only after the change in quoting increments.  相似文献

This study contrasts the call and continuous auction methods using Taiwan Stock Exchange data. Volatility under the call market method is approximately one-half of that under the continuous auction method. The call market method is more effective in reducing the volatility of high-volume stocks than low-volume stocks. This contradicts conventional wisdom which suggests that the call market method is superior for thinly traded stocks, while the continuous auction method is preferred for heavily traded stocks. The call market method does not impair liquidity and price discovery. The call market appears more efficient than in the continuous auction market.  相似文献

Due to the widespread adoption of IFRSs throughout the world and little research on IFRS implementation in developing countries, this study investigates the role of the Securities & Exchange Commission (SEC) regarding IFRS implementation in a developing country. Adopting a mixed methodology (39 interviews and 1647 enforcement documents); the findings have raised concerns as to the adequacy of enforcement mechanisms in implementing IFRSs in Bangladesh. More specifically, only 2.6% of enforcement actions were issued over the period of 1998 to 2010. Political connectedness is the major contributing factor for uneven enforcement activities in Bangladesh. The study also finds that inconsistencies with accounting regulatory framework (Companies Act, BSEC ordinances and IFRSs), multiple regulators, and donor agencies' influence impede the effective implementation of IFRSs. The study also provides policy implications for local and national policy makers namely, IASB, the World Bank and the IMF to rethink about the regulation of IFRSs in developing countries.  相似文献

We examine the clustering pattern in trade and quote prices on the electronic limit order book of the Stock Exchange of Hong Kong (SEHK). Earlier research into clustering focuses on transaction prices only. We study clustering on quote prices over a maximum of five queues on the limit order book. We observe an abnormally high frequency of even and integer prices in trade and quote prices for all tick size groups on the SEHK. The deeper quotes display stronger clustering than the best quotes, indicating that the farther away the quotes are from the best queue, the less information they carry. Our analysis further reveals that an extremely fine tick size itself works as a binding constraint to hinder the price resolution process. We also find that short sale prohibition imposed on the majority of stocks listed on the SEHK causes a significant bias in clustering towards the ask side of the limit order book. This implies that a short sale prohibition impairs efficient price discovery in the market.  相似文献

This study examines the impact of the removal of broker mnemonics on the Sydney Futures Exchange. Early research finds that a decrease in transparency reduces liquidity in the market, whereas more recent research finds that reduced transparency improves market quality. Results of the present study indicate an improvement in liquidity after the removal of broker mnemonics. There is a significant increase in quoted depth and trading volume, and a significant decrease in quoted spreads in the 90 day Bank Accepted Bill, 3 year Treasury Bond and 10 year Treasury Bond Futures. This improvement in liquidity is robust to the length of the event window around the structural change and trading in a control market.  相似文献

The Chicago Mercantile Exchange reduced the size of its S&P 500 futures contract when it reduced the multiplier from 500 to 250 and increased the minimum tick from 0.05 to 0.10 on November 3, 1997. This is a rare major change in a very successful contract's specifications. We analyze effects of this change on liquidity and market dynamics in both a univariate and a multivariate context. The main contribution of this study is the use of multiple intervention analysis with various dynamic response functions to examine the effects of the split while taking into account several other major market events surrounding it. A multivariate analysis is also used to test the impact of the split using a structural model of liquidity and market dynamics. Empirical findings offer limited support for the hypotheses that smaller contract size resulted in smoother trading, and that more public customers trade the S&P 500 futures contract following its split. We observe a reduction in the average transaction size as well as a temporary narrowing of the bid-ask spreads, but no significant change in volatility that can be attributed to the split. We do not find any significant and lasting impact on other liquidity and market variables.  相似文献

This article adds to the literature of accounting regulation by providing background, including facts and circumstances relating to a quarter century of SEC activity preceding the events identified with the reshaping of the capital markets following the dot.com collapse and the attack on the World Trade Center, 11 September 2001. The subsequent collapse of Enron, the bankruptcy of Worldcom, the dissolution of Andersen, one of the Big Five accounting firms, and the passage in the United States of the Sarbanes-Oxley Act, collectively have ushered in a new era of public–private capital market relationships. This study provides guidance and outlines topics useful to future researchers undertaking assessments of regulatory policies and the individuals involved in their administration.
From 1976 to 2001 five individuals played a significant role in the development of the U.S. Securities and Exchange Commission's disclosure and reporting practices by virtue of their office and the collective influence of their views. A. Clarence Sampson (1976–87), Edmund Coulson (1988–91), Walter P. Schuetze (1992–95), Michael H. Sutton (1995–98) and Lynn E. Turner (1998–2001) directed accounting policy activities at the SEC during these years.  相似文献

In this paper, we first compare house price cycles in advanced and emerging economies using a new quarterly house price data set covering the period 1990–2012. We find that house prices in emerging economies grow faster, are more volatile, less persistent, and less synchronized across countries than in advanced economies (AEs). We also find that they correlate with capital flows more closely than in AEs. We then condition the analysis on an exogenous change to a particular component of capital flows: global liquidity, broadly understood as a proxy for the international supply of credit. We identify this shock by aggregating bank‐to‐bank cross‐border credit and by using the external instrumental variable approach introduced by Stock and Watson (2012) and Mertens and Ravn (2013). We find that in emerging markets (EMs) a global liquidity shock has a much stronger impact on house prices and consumption than in AEs. We finally show that holding house prices constant in response to this shock tends to dampen its effects on consumption in both AEs and EMs, but possibly through different channels: in AEs by boosting the value of housing collateral and hence supporting domestic borrowing; in EMs, by appreciating the exchange rate and hence supporting the international borrowing capacity of the economy.  相似文献

This paper studies the exchange rate exposure and its determinants for a sample of nonfinancial Brazilian companies from 1996 to 2006. The results indicate that the number of firms exposed to exchange rate fluctuations is higher in periods of crisis and under a fixed exchange rate regime. In addition, the results point out that, although companies' international activities, operational hedging, and financial policies are important determinants of firms' exposure, the changes in companies' exposure that took place when Brazil moved from a fixed to a floating exchange rate regime were mainly driven by changes in companies' foreign currency borrowing and the use of derivatives that occurred in that period.  相似文献

We present Part 3 of a historical review and analysis of the role played by the Ontario Securities Commission (OSC) in accounting and auditing from the 1960s onward. Part 1 dealt with the period from the 1960s to 1985 (Zeff and Radcliffe, 2010a). Part 2 reviewed the work of the first four chief accountants, from 1986 to 1996 (Zeff and Radcliffe, 2010b). This third and final part reviews the work of the fifth chief accountant, John A. Carchrae, from 1996 to 2008. It began with the reorganization of the OSC and the reassignment of functions. The chief accountant position was now that of a permanent employee, albeit still as head of a very small department. The second part of Carchrae's tenure was dominated by the need to respond to the financial crises of the early 21st century with extensive regulatory change as well as addressing the shift to international accounting standards in Canada.  相似文献

本文在局部均衡框架下建立了引入进口关税的成本加成模型分析国外出口厂商的定价行为,并构建了我国各产业的进口价格、名义有效汇率和国外出口商生产成本指数,利用分布滞后模型首次对各产业的汇率传递效应进行了实证研究。主要发现:无论短期还是长期,各产业进口价格的汇率传递效应都存在很大差异。以采掘、皮革、冶金和纺织为主的资源类产品的进口价格传递弹性普遍较高,甚至超过具有高附加值的机械产业。资源类中以进口稀有金属为主的采掘业长期传递弹性最高。短期内,几乎所有产业的外国出口厂商都会通过调整成本加成来吸收汇率变动;而在长期,汇率变动基本上对各产业进口价格都有不同程度的传递,尤其资源类产业更倾向于采取生产方货币定价方式。结果表明我国一方面可以通过汇率升值提高购买力,另一方面在产业结构调整中则强烈需要改变现有高耗能的增长模式。  相似文献

This study examines the effects of cash dividend payments on stock returns and trading volumes in the stock market. It also investigates whether there is any difference in the investment behavior of investors with respect to the dividend pay out ratio and size in the Istanbul Stock Exchange (ISE)from 1995 to 2003. Prices start to rise a few sessions before cash dividend payments, and on the ex-dividend day, they fall less than do dividend payments, finally decreasing in the sessions following the payment. Trading volume shows a considerable upward shift before the payment date and, interestingly, is stable after Thus, cash dividends influence prices and trading volumes in different ways before, at, and after payment, providing some profitable active trading strategy opportunities around the ex-dividend day. The findings support price-volume reaction discussions on the divident payment date and the significant effect of cash dividends on the stock market.  相似文献

This study proposes a new price impact ratio as an alternative to the widely used Amihud’s (2002) Return-to-Volume ratio. We demonstrate that the new price impact ratio, which is deemed Return-to-Turnover ratio, has a number of appealing features. Using daily data from all stocks listed on the London Stock Exchange over the period 1991–2008, we provide overwhelming evidence that this ratio, while being unequivocal to construct and interpret, is also free of a size bias. More importantly, it encapsulates the stocks’ cross-sectional variability in trading frequency, a relatively neglected but possibly important determinant of stock returns given the recently observed trends in financial markets. Overall, our findings argue against the conventional wisdom that there is a simple direct link between trading costs and stock returns by strongly suggesting that it is the compound effect of trading frequency and transaction costs that matters for asset pricing, not each aspect in isolation.  相似文献

We examine empirically the volatility of four major US dollar spot exchange rates using intraday data over 40 trading days. Using multivariate stochastic volatility models, we investigate the degree of persistence of exchange rate volatility for data sampled at different frequencies and the role of volatility spillovers across exchange rates. We find that the noise component of volatility 'aggregates out' very quickly, being dominated by the more persistent component of volatility for data sampled at 15–minute or lower frequencies. Our results also suggest that exchange rate volatility is very persistent and that cross–currency spillovers are small.  相似文献

In the Paris Bourse some stocks are traded on a spot basis, while others are traded on a monthly settlement basis. The latter are likely to be less subject to leverage and short sales constraints. We empirically analyse the consequences of this difference for the order flow and the return process. Consistent with the theoretical analysis of Diamond and Verrechia (1987), we find that market sell orders are less frequent on the spot market than on the monthly settlement market (although not very significantly) and that the spot market reflects good news (significantly) faster than bad news.  相似文献

This article, Part 2 of a historical review and analysis of the Ontario Securities Commission (OSC), describes the role played by the first four Chief Accountants in the regulation of accounting and auditing from 1986 to 1996. Part 1 dealt with the period from the 1960s to 1985. Part 3 will treat the role played by the fifth Chief Accountant, from 1996 to 2008. As the principal Canadian stock exchange in recent times has been the Toronto Stock Exchange, the OSC has been the most important securities market regulator in Canada. Prior to this article, the academic and professional accounting literature has been largely barren on the OSC’s evolving role on accounting and auditing issues.  相似文献
