Book Description
To uncover the complex feature of the effect of extending trading hours, I analyze what kind of the extension is effective on price efficiency and price stability, by utilizing an agent-based market model. Specifically, I examine whether the partial extension of trading hours--namely, implementing the pre-market session and the after-hours session--and what duration of the session is effective. The simulation result reveals that the implementation of both sessions could have a negative impact on price efficiency and stability if investors' participation during the session is limited; it could result in more concentrated trading in the opening session, wider divergence between market prices and the fundamental value, and lower price stability. In addition, longer sessions are less beneficial (or more harmful). My result also shows that there are very few benefits to trade during the extended-hours sessions. Thus, my findings suggest that the extended-hours trading has a structural weakness which causes illiquidity during the session and lowers price efficiency and price stability during the regular-hour session. However, I find that the implementation of the pre-market session is far more beneficial than that of the after-hours session; exceptionally, the implementation of the short-term pre-market session could induce higher price efficiency and higher price stability regardless of the number of market participants during the session.

Book Description
The extension of trading hours to provide more trading opportunities and improve price efficiency has increasingly been discussed. However, currently, there is limited trading activity during the stock market's extended-hours trading session. Thus, we should examine whether the extension of trading hours is still effective for creating more trading opportunity and price efficiency even if there are few market participants during the extended session. For this study, we build an agent-based market model based on that of Brock and Hommes (1998) and analyze the effect of extending trading hours. We find that although extending trading hours could increase daily trading volume, it could distort price formation and trade opportunity if market participants are limited during the extended-hours session. Specifically, the extension could result in more concentrated trading in the opening session, wider divergence between market prices and the fundamental value of stocks, and higher return volatility (especially at the open).

Book Description
In recent years, spatial analysis has become an increasingly active field, as evidenced by the establishment of educational and research programs at many universities. Its popularity is due mainly to new technologies and the development of spatial data infrastructures. This book illustrates some recent developments in spatial analysis, behavioural modelling, and computational intelligence. World renown spatial analysts explain and demonstrate their new and insightful models and methods. The applications are in areas of societal interest such as the spread of infectious diseases, migration behaviour, and retail and agricultural location strategies. In addition, there is emphasis on the uses of new technologoies for the analysis of spatial data through the application of neural network concepts.

Book Description
Although studies argue that periodic market closure induces the well-known intraday price overreaction, namely, a negative association between intraday returns and overnight returns, no study examines how the overreaction phenomenon is affected by extending trading hours. This study empirically examines it by investigating two Japanese stock futures whose trading hours have been continuously and asynchronously extended. Surprisingly, the overreaction is stronger when the extended-hours session is longer, and trading activity during the session is higher. The result indicates that the extension can worsen the overreaction phenomenon, highlighting the existence of the negative impact of trading hours extension on price efficiency.

Book Description
The New York Stock Exchange extended its trading hours by 30 min in 1974 and in 1985; the first extension resulting in a delayed close and the second in an early open. We find a shift in volume to the new period after each extension. Additionally, there is a larger increase in volume after the 1985 extension than after the 1974 extension. We argue that the second effect is explained by the first. The extension at the end of the day allows some investors to postpone their trades, which results in occasional information cancellation or discovery; this mutes the effect of the extension on volume. In contrast, the extension at the start of the day allows some investors to accelerate trades, which precludes information cancellation or discovery and its negative effect on volume. This explanation suggests that the effect of an extension on volume depends, at least in part, on its timing.

Book Description
On November 20, 1998, the Hong Kong Futures Exchange started opening its markets fifteen minutes earlier than the opening time and closes its markets fifteen minutes later than the closing time of the Hong Kong Stock Exchange. In this paper we utilize the Geweke feedback measures to examine the effect of extended trading hours of the Hong Kong index futures on the information flow between futures and cash markets. We find that extending the trading hours leads to a stronger information flow from the cash market to the futures market.

Book Description
Franklin R. Edwards Hugh T. Patrick As the 19908 unfold, we stand on the threshold of a new age of global financial markets. The seeminglyinevitable, market-driven dynamicofthe international integration of banking, securities, and futures markets is bringing about a profound transformation of financial flows and the efficiency and effectiveness of the domestic and international markets serving them. Propelled in the 1980s by a variety offorces-technological, economic, political, and (de)regulatory-the implications of international financial market integration are pervasive. This new era promises to raise a host of new public and business policy issues as well as opportunities. These include issues of financial market integrity, international competitiveness, and regulatory harmony. What will the rules of the game be? How will prudential concerns for the safety as well as the efficiency of international financial markets, and their national counterparts, be met? What are the appropriate new institutional arrangements? How and to what degree will international financial mar kets be supervised, harmonized, and regulated, and for what purposes? Whowill be makingthese decisions andimplementingthem?Thesearethe issues that confront-and bedevil-policymakers, practitioners, and scho lars alike. 1 2 INTRODUcnON The Context The 1980s were witness to major transformations of the international political, economic, andfinancial environment. Amongthe majordevelop ments was rapidly increasing international financial market integration across major nations and across financial product markets. The major sources of financial change were several, interrelated, and reinforcing.
