Transaction Costs and Price Volatility: New Evidence from the Tokyo Stock Exchange

We investigate the volatility impacts of the full commission deregulation in Japan in October 1999, and find that the deregulation overall tends to significantly increase price volatility in the Japanese equity market, using alternative model specifications and control variables. This finding contrasts with previous evidence that implies a positive relation between transaction costs and price volatility, while consistent from the converse with the hypothesis proposed by Stiglitz (1989) and Summers and Summers (1989). Our results suggest that imposing higher transaction costs might still be a feasible policy tool for stabilizing the market by curbing short-term noise trading.

The Politics of Transaction Costs

This article aims to develop a model for analysing the operation and outcomes of the contracting process as it applies to public services, and to explore the politics of transaction costs involved in this process using a case study of Compulsory Competitive Tendering (CCT) in the UK. For this purpose the article deals with the policy outputs from two time periods, 1991 and 1994, which are regarded as the most dynamic years in terms of CCT policy implementation. The article also demonstrates how transaction costs may be manipulated in the contracting process by the interested parties. Finally, it suggests that the politics of transaction costs should be studied systematically in the future.     

Learning, Cascades, and Transaction Costs

The paper analyzes the effect of transaction costs on sociallearning in an asset market with asymmetric information, sequentialtrading, and a competitive price mechanism. Both fixed and proportionaltransaction costs reduce the information content of tradingorders and lead to informational cascades. If transaction costsare very high, an informational cascade may occur not only whenbeliefs converge on a specific asset value but also when thereis extreme uncertainty about the asset's fundamental value.Finally, if the value in the bad state is sufficiently low,proportional transaction costs lead to an informational cascadeonly when prices are very high.

Institutional Investors, Analyst Following, and the January Anomaly

Average stock returns for small, low stock price firms are higher in January than for the rest of the year. Two explanations have received a great deal of attention: tax-loss selling and gamesmanship. This paper documents that seasonality in returns is not a phenomenon observed only for small firms' stock or those with low prices. Strong seasonality in excess returns is reported for a sample of widely followed firms. Sample firms have unusually low excess returns in January and returns adjust upward over the year. These results are consistent with the gamesmanship hypothesis, but not the tax-loss-selling hypothesis.     

Dealer Bid-Ask Quotes and Transaction Prices: An Empirical Study of Some AMEX Options

This paper, utilizing dealer's “trading book” information, presents some empirical evidence supporting the validity of a dealer pricing model. It shows that much of the transaction prices variation may be explained by the specialist's optimal determination of his bid and ask quotes. Furthermore, it demonstrates that the dealer's bid-ask spread is an important explanatory variable in the observed transaction return. Finally, it indicates that the dealer's inventory level may affect his quotes and thus the transaction prices and order arrivals. The paper provides insights into the relationship between transaction prices and equilibrium prices, which will permit more extensive use of transaction data in empirical investigations. It also provides a better understanding of optimal dealer pricing strategies, suggesting that the proposed empirical model may be used to evaluate a dealer's trading performance.

企业制度性交易成本的表现、成因及其治理

企业制度性交易成本是企业遵从政府管制的耗费,对企业的生存与发展在边际意义上起着关键性的作用.当前,我国企业制度性交易成本依然偏高,主要表现为部分显性制度性交易成本隐性化,行政审批制度导致的企业人力、时间与机会成本较高,涉企收费依然偏多,企业履约与诉讼成本高昂.降低企业制度性交易成本应当远近结合、标本兼治,在进一步清理和规范涉企收费的基础上,着力构建商业友好型政府管制环境,推动国家治理体系的现代化.     

The Non-Stationarity of Share Price Volatility

This article examines first the changes over time in the variance of the market return on the Sydney Stock Exchange. It concludes that variance changes at a frequency greater than previously accounted for. Some of these changes coincide with political and economic events. Next the market returns are demonstrated to have a normal distribution. This result follows once the frequency of standardization is matched to the frequency of changes in variance.     

Components of the Bid-Ask Spread and the Statistical Properties of Transaction Prices

The bid-ask spread can be decomposed into two parts: one part due to asymmetric information and the other part due to other factors such as monopoly power. The part due to asymmetric information attenuates statistical biases in mean return, variance, and serial covariance. Thus, using spread data to adjust for biases in return moments requires knowing not only the spread but the composition of the spread. Furthermore, any spread-estimation procedure using transaction prices must estimate two spread components. On the other hand, the appropriateness of some previously suggested statistical corrections is independent of the spread composition.     

Liquidity, Transaction Costs, and Reintermediation in Electronic Markets

Relationships between trading cost, technology, and the nature of intermediation in the trading services industry are discussed. Electronic markets are linked to reductions in trading costs. Lower explicit costs are related to system development and operating costs. Electronic order book information is identified as a means of realizing implicit cost savings. The concept of liquidity management in electronic environments is introduced, and its potential is empirically illustrated. The empirical results suggest new roles for brokerage and exchange operations, and competition between the two. Competitive advantage with respect to the provision of liquidity management services is compared across types of intermediaries.     

透明度变化对股票市场投资者委托单提交行为和交易成本影响研究

基于2003年12月8日沪深交易所交易前市场透明度改革背景,本文利用一家营业部的投资者报价和交易数据,研究同一个机构投资者和散户投资者在透明度改革前后委托单提交激进程度的变化,以及这种变化对其完成交易的成本的影响。我们发现,透明度改革前后,机构投资者的委托单提交激进程度都显著大于散户投资者的委托单提交激进程度。透明度增加以后,机构投资者的委托单激进程度显著减少,而散户投资者的委托单提交激进程度增加。同时发现,透明度增加以后,机构投资者通过分拆委托单,增加交易次数,导致完成交易的时间增加,但价格影响力基本没有变化,散户投资者的成交时间和价格影响力有显著改善。     

Predictability and Transaction Costs: The Impact on Rebalancing Rules and Behavior

Recent papers show that predictability calibrated to U.S. data has a large effect on the rebalancing behavior of a multiperiod investor. We find that this continues to be true in the presence of realistic transaction costs. In particular, predictability causes the no-trade region for the risky-asset holding to become state dependent and, on average, wider and higher. Predictability also motivates the investor to spend considerably more on rebalancing and to rebalance more often. In other results, we find that introducing costly liquidation of the risky asset for consumption lowers the average allocation to the risky asset, though only marginally early in life. Our experiments also vary the nature of the return predictability and introduce return heteroskedasticity.

The Effects of Transaction Costs and Different Borrowing and Lending Rates on the Option Pricing Model: A Note

This paper modifies the Black-Scholes option pricing model to include the effects of transaction costs and different borrowing and lending rates. The paper demonstrates that these market imperfections tend to offset each other yielding a bounded range of prices for each option. The paper also shows that under some conditions the option pricing hedge may be society's lowest cost financial intermediary.     

Transaction Costs and the Pricing of Assets

The existence of transaction costs explains why investors do not fully diversify their portfolios. This paper examines the implications of such limited diversification on equilibrium asset prices in the framework of the capital asset pricing model. In the pricing equation obtained here an asset's risk premium depends on a weighted average of its covariance with the market and its own variance.     

The Effect of Option Listing on Bid-Ask Spreads,Price Volatility,and Trading Activity of the Underlying OTC Stocks

This paper examines the changes in spreads, price volatility, and trading activity surrounding option listing for a sample of 144 OTC stocks. For this sample, both price volatility and volume increase, but the evidence on spreads is mixed. The increase in price volatility is attributed primarily to an increase in residual return variances. Furthermore, price volatility increases even after controlling for volume, insider trading, and spreads. Although these variables do not fully explain the causes for the increase in price volatility after option listing, the results suggest that liquidity trading or volume has a stronger effect on price volatility than insider trading. This study also finds that both the number of trades and institutional holdings show substantial increases, which are supportive of the notion that listing of options on OTC stocks attracts more attention.     

The Share Price Impact of UK CCA Disclosures

This study investigates the impact of the experimental standard, SSAP16 (Current Cost Accounting), on share returns on the London stock market. Approximately 200 companies were examined between 1980–84. The experimental design specifies current cost as a supplementary signal to historical cost and employs two main statistical tools: ordinary least squares regression and the abnormal performance metric. In addition, a number of different CCA measurements are specified in order to assess the sensitivity of the results and to ease comparison with other studies. The results suggest that CCA information has a small but significant impact on stock returns in the days up to announcement. However, CCA does not seem to be the main driving force behind long period returns. Returns in the long run are associated more closely with historical cost information than with that generated by SSAPI6.
