Market Structure, Informational Efficiency and Liquidity
Author: Erik Theissen
Publisher:
ISBN:
Category :
Languages : en
Pages : 48
Book Description
This paper reports the results of 18 market experiments that were conducted in order to compare the call market, the continuous auction and the dealer market. The design incorporates asymmetric information but guarantees that the ex-ante quality of the private signals of all traders is identical. Therefore, the aggregation of diverse information can be analyzed in the absence of insider trading. Single transaction prices in the call and continuous auction market are found to be much more efficient than prices in the dealer market. The latter is, however, very efficient when average prices are analyzed. Averaging the prices of a trading period largely eliminates the bid-ask spread. The conclusion is therefore that prices in a dealer market convey high quality information, but at the expense of high transaction costs. The call market, although exhibiting small pricing errors, shows a systematic tendency towards underadjustment to new information. An analysis of market liquidity using various measures proposed in the literature shows that execution costs are lowest in the call market and highest in the dealer market. The analysis also reveals that both the trading volume and Roll's (1984) serial covariance estimator are inappropriate measures of execution costs in the present context. The quality of the private signals traders receive influences portfolio structure but does not influence end-of-period wealth. This result is consistent with efficient price discovery in the experimental markets.

Pages : 31
Book Description
This paper reports the results of 18 experimental asset markets with 262 subjects that explore the effects of liquidity and aggregation of information. The main focus lies on the comparison of different trading mechanisms of stock exchanges. Compared to most of financial markets experiments, reality is met by introducing long-living assets and integrating all subjects in a multi-period decision-making process.In accordance with the evidence from the empirical research in real financial markets, our results show that the continuous auction achieves the highest informational efficiency. Dealer markets do the worst; call markets (batch trading) reach an intermediate position. A comparable result is achieved regarding the liquidity of the trading mechanisms.For both success factors of real stock exchanges our results show a strong tendency that continuous trading outperforms the other market structures, at least in the framework of the present measurement and on the chosen abstraction level. This does not exclude for the practice to offer a combination with call markets in certain titles and at certain times, particularly, if the here met assumptions of an open market access and information symmetry between the investors do not apply in full extent.

Measuring Liquidity in Financial Markets
Author: Abdourahmane Sarr
Publisher: International Monetary Fund
ISBN:
Category : Business & Economics
Languages : en
Pages : 72
Book Description
This paper provides an overview of indicators that can be used to illustrate and analyze liquidity developments in financial markets. The measures include bid-ask spreads, turnover ratios, and price impact measures. They gauge different aspects of market liquidity, namely tightness (costs), immediacy, depth, breadth, and resiliency. These measures are applied in selected foreign exchange, money, and capital markets to illustrate their operational usefulness. A number of measures must be considered because there is no single theoretically correct and universally accepted measure to determine a market's degree of liquidity and because market-specific factors and peculiarities must be considered.

Publisher: Springer Nature
ISBN: 3030748170
Category : Business enterprises
Languages : en
Pages : 111
Book Description
This open access book addresses four standard business school subjects: microeconomics, macroeconomics, finance and information systems as they relate to trading, liquidity, and market structure. It provides a detailed examination of the impact of trading costs and other impediments of trading that the authors call rictions It also presents an interactive simulation model of equity market trading, TraderEx, that enables students to implement trading decisions in different market scenarios and structures. Addressing these topics shines a bright light on how a real-world financial market operates, and the simulation provides students with an experiential learning opportunity that is informative and fun. Each of the chapters is designed so that it can be used as a stand-alone module in an existing economics, finance, or information science course. Instructor resources such as discussion questions, Powerpoint slides and TraderEx exercises are available online.

Automating the Price Discovery Process
Author: Mr.Ian Domowitz
Publisher: International Monetary Fund
ISBN:
Category : Business & Economics
Languages : en
Pages : 38
Book Description
Automated trade execution systems are examined with respect to the degree to which they automate the price discovery process. Seven levels of automation of price discovery are identified, and 47 systems are classified according to these criteria. Systems operating at various levels of automation are compared with respect to age, geographical location, and type of securities traded. Information provided to market participants, and asymmetries of information between traders with direct access to the automated market and outside investors also are examined. It is found, for example, that the degree of asymmetric information increases with the level of automation of price discovery. The potential for trading abuses related to prearranged trading, noncompetitive execution, and trading ahead of customers is analyzed for each level of automation. Certain levels of automation widen the opportunities for trading abuses in some respects, but may narrow them in others.

The Effect of Fast Traders in Continuous Double Auction Market
Author: Kyubin Yim
Publisher:
ISBN:
Category :
Languages : en
Pages : 29
Book Description
In this paper, we investigate the effect of fast traders in continuous double action markets using agent-based modeling. We consider two agent types, such as fast and slow traders, by preference of investment time in a high-risk environment. Additionally, the order aggressiveness of agents with superior information and the rule of the updating agent type using a performance measure based on a realized profit are considered in our model. We find several results with rich economic implications: (i) with the non-updating agent type, the model reproduces the positive role of fast traders in previous models and empirical studies, in which they increase market efficiency and liquidity; (ii) with the updating agent type, the model provides empirical implications such as the decrease in fast traders' profit; (iii) as uncertainty is reduced when updating agent types, fast traders who take more risks than slow traders can survive in the model. This paper provides a more integrated understanding of fast or high-frequency trading in the financial market.

Market Design and the Efficiency of a Stock Market Under Liquidity Stress
Author: Shmuel Hauser
Publisher:
ISBN:
Category :
Languages : en
Pages : 66
Book Description
Stock exchanges around the world are challenged by extreme liquidity events. We examine how trading design affects the informational efficiency of markets under liquidity stress due to opening of trade and the expiration of stock index derivatives. To give markets time to incorporate overnight and weekend information efficiently, most exchanges open trading using a preopening period followed by a call auction. To further improve their ability to accommodate extreme liquidity events exchanges have switched from fixed to random opening times. We investigate the effects of opening time randomization on informational efficiency of opening and preopening stock prices on stock index options expiration days and other days. Randomization has significantly improved price discovery and reduced transitory volatility and price distortion, especially on index options expiration days. Randomization offers exchanges a simple and effective way to mitigate stressful effects of extreme liquidity events. It also helps traders settle their options positions using prices that are closer to their true values, which improves the hedging effectiveness and price discovery provided by options.
