This paper examines the effects of disclosures on information asymmetry by studying bid-ask spreads around independent management forecasts and earnings announcements released with forecasts. The findings suggest the disclosure of independent management forecasts increase information asymmetry in the market rather than resolving it. Regulation FD has reduced the overall level of information asymmetry in the market with respect to both earnings announcements and management forecasts although it has a greater effect on management forecasts, post-forecast spreads. Closer analysis reveals that when “good news” forecasts and separated from “bad news” independent management forecasts, good news management forecasts decrease information asymmetry. Since initial tests demonstrated that management forecasts increase information asymmetry, these findings suggests that the magnitude of the effect of bad news management forecasts is greater than that of good news forecasts.

This dissertation consists of 3 essays that examine the impact of electronic screen trading in futures markets. The research provides empirical evidence on increasingly significant issues given the rapid global advances in technology used in securities markets. Each essay addresses the scarcity of conclusive research in order to aid researchers, regulators, exchange policy makers and systems builders as they confront issues related to electronic trading systems.

Vilken effekt frivilligt redovisad information har på kapitalmarknaden är en omstridd fråga i litteraturen. Vissa menar att mer information minskar informationsasymmetrin på kapitalmarknaden medan andra finner motsatt resultat, där en förklaring är information overload. Denna studie bidrar till frågan genom att studera rapportlängden samt informationsinnehållet i kvartalsrapporter från 155 bolag noterade på Nasdaq Stockholm under åren 2015-2016, där bid-ask spread och handelsvolym används som mått på informationsasymmetri. Av fyra genomförda regressionsanalyser visar två signifikanta resultat. De signifikanta resultaten visar att frivilligt redovisad information höjer handelsvolymen, vilket indikerar att informationsasymmetrin på kapitalmarknaden minskar. Detta resultat har betydelse för såväl företag som standardsättare såsom IASB eftersom det tyder på att den svenska marknaden efterfrågar mer redovisad information.

abstract: Given the "New Nine Measures" for capital market reform, a policy document issued by the State Council of China, the development of markets for interest rate derivatives, such as treasury futures, becomes an increasingly important task. Several shortcomings of the existing treasury futures market have been noted: including low market liquidity, singular investor composition, restrict contract terms, and low hedging demand. This study contributes to a better understanding of the treasury futures market by analyzing changes in China treasury futures market regulations and their impact on market liquidity of treasury futures. Found that compared with the mature market, China treasury futures market exists liquidity shortage, the trading system, market structure and the division of regulatory are factors which influence the liquidity of China treasury futures market. This study found that reducing transaction costs for further optimization of the width and depth of China treasury futures market are not obvious by using quantitative analysis method, expanding the smallest change price can optimize the market depth, reducing transaction costs and expanding smallest change price can optimize the immediacy, volume and hosting amount. In addition, the bond market will also influence the treasury futures market, the price fluctuations and the morphology of the yield curve of bond market have significant influence on width, depth and holdings of market. The system of China treasury futures market needs to be optimized by expanding the smallest change price and reducing transaction costs. The market structure needs to be optimized by establishing unified bond market and enriching investor structure. These findings have significant theoretical and practical implications. The study also provides policy recommendations for the design and establishment of treasury futures market to the regulatory agencies. / Dissertation/Thesis / Doctoral Dissertation Business Administration 2016

Abstract This thesis investigates a set of equity market phenomena associated with investors' trading activity, using a comprehensive Finnish Central Securities Depository (FCSD) database that records practically all trades by Finnish investors. This database enables us to classify a large number of heterogeneous investors using both economic and institutional characteristics. The first essay classifies investors by trading activity. It analyzes trading styles of active and passive investors during the boom in technology stocks 1997–2000. We find that the herding tendency of active investors grew monotonically, year by year. Particularly large active investors used momentum and growth strategies. Moreover, buy pressures of active investors were positively related to contemporaneous daily returns. Passive investors, on the other hand, herd very strongly and their trading exhibited a contrarian style throughout the sample period. The second essay focuses on the relation between day trading of individual investors and intraday stock price volatility. I find a strong positive relation between the individual investors' day trades and volatility for actively day traded stocks. This finding suggests that day trading tends to increase volatility and/or day traders tend to become more active on the days of high volatility. The third essay tests the theoretical proposition of Amihud and Mendelson (1986) that investors hold assets with higher bid-ask spreads for longer periods. We measure holding periods of individual investors directly and find that they are positively related to spreads. The models control for a variety of other stock characteristics (e.g. value vs. growth orientation) and investors' attributes (e.g. gender) affecting holding periods. The fourth essay studies how both individual and institutional investors with different levels of capital gains and losses react to earnings announcements. I find that both sign and magnitude of capital gains affect individual investors' abnormal trading volumes. Individual investors are less prone to sell when they are carrying loses rather than gains. Furthermore, they react less to earnings announcements when capital gains or losses are large (over 20%). Taken together these findings provide support for prospect theory. Institutional investors appear to be less affected by psychological factors underlying prospect theory.

In the restaurant industry, information gap between inside management and outside stakeholders could be considerable due to analyst’ lack of interest in the restaurant industry and restaurant firms’ high intangible asset and scant corporate payout. Given the possible seriousness of information asymmetry in the restaurant industry, the subject of information asymmetry could bear great importance in the restaurant industry. Nevertheless, information asymmetry has never been the subject of study in the restaurant industry, not to mention the hospitality industry generally. With this research gap in mind, this study conducted extensive research to understand the various implications of information asymmetry in the restaurant industry. The first objective of this study was to examine the magnitude of information asymmetry in the restaurant industry. This study demonstrated the seriousness of information asymmetry in the restaurant industry by showing that the size of information asymmetry within the restaurant industry is greater than that of other services industries (i.e., utility, REIT, and airline industries). The second objective of this study was to examine the unique determinants of information asymmetry in the restaurant industry. The results of this study showed that in the restaurant industry, information asymmetry widens as the size of accruals increases. Additionally, information asymmetry was found to be smaller for franchise restaurants than for non-franchise restaurants. The third objective of this study was to investigate the impact of information asymmetry on some managerial behaviors in the restaurant industry. This study showed that in the restaurant industry, information asymmetry leads to a manager’s reduced corporate payout and increased investment inefficiency. The last objective of this study was to examine the impact of information asymmetry on firm value in the restaurant industry. By demonstrating a curvilinear relationship between information asymmetry and firm value, this study showed that there exists not only a negative impact of information asymmetry but also a positive impact of information asymmetry on firm value in the restaurant industry. Furthermore, this study showed that the positive impact of information asymmetry on firm value is more prominent for high-leveraged and mature firms than their counterpart groups. This study’s results not only help understand the characteristics of information asymmetry in the restaurant industry but also introduce a new window for understanding managerial behaviors and firm value in the restaurant industry.
