Book Description
This paper analyses the ability of beta and other factors, like firm size and book-to-market, to explain cross-sectional variation in average stock returns on the Swedish stock market for the period 1980-1997. We use a bivariate GARCH(1,1) process to estimate time-varying betas for asset returns. The estimated variances of these betas, derived from a Taylor series approximation, are used for correcting errors in variables problem. Our model accounts for problems such as cross-sectional and intertemporal heteroscedasticity. An Extreme Bounds Analysis is utilized for testing the sensitivity of the estimated coefficients to changes in the set of included explanatory variables. Since the tests are carried out on realized returns, which presumably are quite noisy approximations of expected returns; we also analyze if the variables play different roles depending on if it is a Bull or Bear market. Our results show that the coefficient for beta is never significantly different from zero, while variables book to market, size and leverage have significant coefficients. Different sensitivity analyses suggest that the results, to some extent, may be due to cross-correlations between the variables, the characteristics of the extreme periods included in the sample, the average sign of the excess market return during the sample period, and the choice of the estimation and test methods. The findings also show that the estimated conditional beta is a more accurate measure of the true market beta than the beta estimated by OLS.

Book Description
Using the dual-beta model of Bhardwaj and Brooks (1993), thisstudy examines the cross-section of realized stock returns. Bull-market betas are significantly positively related to returns and, except for some models in January, bear-market betas are significantly negatively related to returns. These relationships are not lost even after other independent variables, including size, book-to-market equity, and an earnings-price ratio, are added to the cross-sectional regressions. Book-to-market equity is an important factor in bear, but not bull, markets. Size is important in January and bear markets during February through December.

Book Description
A collection of essays in honour of Clive Granger. The chapters are by some of the world's leading econometricians, all of whom have collaborated with and/or studied with both) Clive Granger. Central themes of Granger's work are reflected in the book with attention to tests for unit roots and cointegration, tests of misspecification, forecasting models and forecast evaluation, non-linear and non-parametric econometric techniques, and overall, a careful blend of practical empirical work and strong theory. The book shows the scope of Granger's research and the range of the profession that has been influenced by his work.

Book Description
The second edition of this authoritative textbook continues the tradition of providing clear and concise descriptions of the new and classic concepts in financial theory. The authors keep the theory accessible by requiring very little mathematical background. First edition published by Prentice-Hall in 2001- ISBN 0130174467. The second edition includes new structure emphasizing the distinction between the equilibrium and the arbitrage perspectives on valuation and pricing, as well as a new chapter on asset management for the long term investor. "This book does admirably what it sets out to do - provide a bridge between MBA-level finance texts and PhD-level texts.... many books claim to require little prior mathematical training, but this one actually does so. This book may be a good one for Ph.D students outside finance who need some basic training in financial theory or for those looking for a more user-friendly introduction to advanced theory. The exercises are very good." --Ian Gow, Student, Graduate School of Business, Stanford University Completely updated edition of classic textbook that fills a gap between MBA level texts and PHD level texts Focuses on clear explanations of key concepts and requires limited mathematical prerequisites Updates includes new structure emphasizing the distinction between the equilibrium and the arbitrage perspectives on valuation and pricing, as well as a new chapter on asset management for the long term investor

Book Description
We investigate how corporate stock returns respond to geopolitical risk in the case of South Korea, which has experienced large and unpredictable geopolitical swings that originate from North Korea. To do so, a monthly index of geopolitical risk from North Korea (the GPRNK index) is constructed using automated keyword searches in South Korean media. The GPRNK index, designed to capture both upside and downside risk, corroborates that geopolitical risk sharply increases with the occurrence of nuclear tests, missile launches, or military confrontations, and decreases significantly around the times of summit meetings or multilateral talks. Using firm-level data, we find that heightened geopolitical risk reduces stock returns, and that the reductions in stock returns are greater especially for large firms, firms with a higher share of domestic investors, and for firms with a higher ratio of fixed assets to total assets. These results suggest that international portfolio diversification and investment irreversibility are important channels through which geopolitical risk affects stock returns.

Book Description
The distinction between out-performance of an Investment fund or plan manager vs rewards for taking risks is at the heart of all discussions on Investment fund performance measurement of fund managers. This issue is not always well-understood and the notion of risk adjusting performance is not universally accepted. Performance Measurement in Finance addresses this central issue. The topics covered include evaluation of investment fund management, evaluation of the investment fund itself, and stock selection performance. The book also surveys and critiques existing methodologies of performance measurement and covers new innovative approaches to performance measurement. The contributors to the text include both academics and practitioners providing comprehensive coverage of the topic areas. Performance Measurement in Finance is all about how to effectively measure financial performance of the fund manager and investment house managers, what measures need to be put in place and technically what works and what doesn't. It covers risk, and what's acceptable and what isn't, how, in short, to manage risk. Includes practical information to enable Investment/Portfolio Managers to understand and evaluate fund managers, the funds themselves, and Investment firms Provides a full overview of the topic as well as in-depth technical analysis
