Information Uncertainty And The Momentum Effect, Nicholas Liu Chang Cher
Information Uncertainty And The Momentum Effect, Nicholas Liu Chang Cher
Dissertations and Theses Collection (Open Access)
I identify simple proxies for uncertainty and attempt to determine if the returns to a momentum strategy vary with these proxies. The proxies identified include the stock's daily 6-month historical return volatility, the magnitude of alpha in a 6-month historical regression of the stock's daily returns on the Fama-French factors and the (1-R2) value of the regression. The exposures to each of the risk factors were also tested as possible proxies for uncertainty related to the factors.
Using daily stock return data from CRSP from 1926 to 2006, stocks are first sorted into quintiles based on these proxies. A momentum …
Offshore Financial Havens: Their Role In International Capital Flows, Zhixiang Sun
Offshore Financial Havens: Their Role In International Capital Flows, Zhixiang Sun
Dissertations and Theses Collection (Open Access)
The purpose of this paper is to study the role of offshore financial havens in international capital flows. We examine the effects of being a tax haven, a money laundering centre or an offshore financial centre (OFC), which often overlap. We want to see whether these places are used as entrepots (which means temporary storage for funds) or as investment places or both. We mainly use two complementary data sets: bilateral cross-border asset holding and financial intermediation. One is a stock variable and the other one is a flow variable. We apply the gravity model to bilateral cross-border asset holding …
Rolling Adf Tests: Detecting Rational Bubbles In Greater China Stock Markets, Peng Huang
Rolling Adf Tests: Detecting Rational Bubbles In Greater China Stock Markets, Peng Huang
Dissertations and Theses Collection (Open Access)
Following Phillips, Wu and Yu (2007), this paper extends their bubble detecting work to several Greater China stock markets. Two alternative bubble detecting methods, the forward recursive ADF tests raised by Phillips et al. (2007) and the modified version, forward rolling ADF tests, are implemented and compared. Monte Carlo simulations are performed to determine the critical values of the ADF statistic under different sample size. Empirical results demonstrate that only rolling ADF tests are successful in detecting rational bubbles by overcoming the problem of periodically collapsing bubble. As we have expected, bubbles in China Mainland stock market are detected. Out …
Stock Markets And Income Inequality: A Cross-Country Study, Elizabeth Mathew
Stock Markets And Income Inequality: A Cross-Country Study, Elizabeth Mathew
Dissertations and Theses Collection (Open Access)
This paper conducts a comprehensive analysis to understand how stock market ratios affect net income inequality. The study of how finance impacts income distribution is relevant as the income distribution of a nation influences savings decisions, resource allocation, innovation incentives and public policy and hence impacts the process of economic development. Using a cross-sectional data set of 68 countries and panel data set of 61 countries from 1975 to 2005, I apply cross-sectional OLS and panel regressions to look at how stock market size, liquidity, and activity impact income inequality. While stock market size is found to strongly impact income …
Flow-Performance Relationship And Tournament Behavior In The Mutual Fund Industry, Baoling Ma
Flow-Performance Relationship And Tournament Behavior In The Mutual Fund Industry, Baoling Ma
Dissertations and Theses Collection (Open Access)
In this paper, we interpret the flow-performance relationship as an incentive scheme implicitly given to mutual fund managers by mutual fund investors. We show that the flow-performance relationship varies not only with economic activity but also across fund attributes. We provide evidence that the degree of convexity of the flow-performance relationship has a positive effect on the magnitude of tournament behavior. Different from the conventional tournament hypothesis, we show that although the convexity of the flow-performance relationship does produce implicit incentives for fund managers to modify risk-taking behavior as a function of their prior performance, whether or not the mid-year …
Corporate Entrepreneurship As Resource Capital Configuration In Emerging Market Firms, Daphne W. Yiu, Chung-Ming Lau
Corporate Entrepreneurship As Resource Capital Configuration In Emerging Market Firms, Daphne W. Yiu, Chung-Ming Lau
Research Collection Lee Kong Chian School Of Business
Network-based resource capital such as political capital, social capital, and reputational capital are critical in providing firms with special access to various resources and legitimacy in emerging markets. However, how these generic nonmarket forms of capital are transformed into value-adding, industry-specific, and firm-specific uses, which subsequently enhance firm competitiveness, remained unanswered. Adopting a dynamic capability approach, this paper posits that corporate entrepreneurship performs a unique role of resource capital configuration and transformation in emerging market firms by continuously renewing firm competences so that congruence with the changing environment can be achieved. Building on this conceptualization, we argue that the positive …
An Efficient Method For Maximum Likelihood Estimation Of A Stochastic Volatility Model, Junying, Shirley Huang, Jun Yu
An Efficient Method For Maximum Likelihood Estimation Of A Stochastic Volatility Model, Junying, Shirley Huang, Jun Yu
Research Collection Lee Kong Chian School Of Business
In this paper an efficient, simulation-based, maximumlikelihood (ML) method is proposed for estimating Taylor’sstochastic volatility (SV) model. The new method isbased on the second order Taylor approximation to the integrand.The approximation enables us to transfer the numericalproblem in the Laplace approximation and that inimportance sampling into the problem of inverting two highdimensional symmetric tri-diagonal matrices. A result recentlydeveloped in the linear algebra literature shows thatsuch an inversion has an analytic form, greatly facilitatingthe computations of the likelihood function of the SVmodel. In addition to provide parameter estimation, the newmethod offers an efficient way to filter, smooth, and forecastlatent log-volatility. The …
The Effect Of Rivals When Firms Emerge From Bankruptcy, Gary L. Caton, Jeffrey Donaldson, Jeremy Goh
The Effect Of Rivals When Firms Emerge From Bankruptcy, Gary L. Caton, Jeffrey Donaldson, Jeremy Goh
Research Collection Lee Kong Chian School Of Business
Studies on the announcement effects of bankruptcy filings have found that when a firm files for Chapter 11 bankruptcy protection its shareholders suffer significant losses. A recent paper extends these findings by investigating the announcement effect on rival companies, while another examines the equity performance of firms emerging from bankruptcy. We combine these two lines of inquiry by examining the effect on rivals when a firm emerges from the protection of Chapter 11. We find both significant negative stock market returns and significant negative revisions in analysts’ earnings forecasts for rivals of successfully reorganized companies.
Harmful Help: The Costs Of Backing Up Behavior In Teams, Christopher M. Barnes, J. R. Hollenbeck, David Turley Wagner, D. S. Derue, J. D. Nahrgang, K. M. Schwind
Harmful Help: The Costs Of Backing Up Behavior In Teams, Christopher M. Barnes, J. R. Hollenbeck, David Turley Wagner, D. S. Derue, J. D. Nahrgang, K. M. Schwind
Research Collection Lee Kong Chian School Of Business
Prior research on backing-up behavior has indicated that it is beneficial to teams (C. O. L. H. Porter, 2005; C. O. L. H. Porter et al., 2003). This literature has focused on how backing-up behavior aids backup recipients in tasks in which workload is unevenly distributed among team members. The authors of the present study examined different contexts of workload distribution and found that, in addition to the initial benefits to backup recipients, there are initial and subsequent costs. Backing-up behavior leads backup providers to neglect their own taskwork, especially when workload is evenly distributed. Team members who receive high …
Firm Diversification And Earnings Management: Evidence From Seasoned Equity Offerings, Chee Yeow Lim, Tiong Yang Thong, David K. Ding
Firm Diversification And Earnings Management: Evidence From Seasoned Equity Offerings, Chee Yeow Lim, Tiong Yang Thong, David K. Ding
Research Collection Lee Kong Chian School Of Business
Popular press suggests that diversified firms are more aggressive in managing earnings than non-diversified firms. We examine this claim in the seasoned equity offering (SEO) setting, where firms have been shown to have the incentive to manage earnings upwards. Using the cross-sectional modified Jones [(1991) J Accounting Res 29:193–228] model to measure discretionary current accruals, we find that discretionary current accruals are higher among diversified firms than in non-diversified ones. Our evidence is consistent with the view that the extent of firm diversification is directly related to the degree of earnings management. We further show that diversified issuers with high …
Implications Of Transaction Costs For The Post-Earnings-Announcement Drift, Jeffrey Ng, Rodrigo Verdi, Tjomme Rusticus
Implications Of Transaction Costs For The Post-Earnings-Announcement Drift, Jeffrey Ng, Rodrigo Verdi, Tjomme Rusticus
Research Collection School Of Accountancy
This paper examines the effect of transaction costs on the post–earnings announcement drift (PEAD). Using standard market microstructure features we show that transaction costs constrain the informed trades that are necessary to incorporate earnings information into price. This implies weaker return responses at the time of the earnings announcement and higher subsequent returns drift for firms with higher transaction costs. Consistent with this prediction, we find that earnings response coefficients are lower for firms with higher transaction costs. Using portfolio analyses, we find that the profits of implementing the PEAD trading strategy are significantly reduced by transaction costs. In addition, …
Multi-Echelon Repairable Item Inventory System With Limited Repair Capacity Under Nonstationary Demands, Hoong Chuin Lau, Huawei Song
Multi-Echelon Repairable Item Inventory System With Limited Repair Capacity Under Nonstationary Demands, Hoong Chuin Lau, Huawei Song
Research Collection School Of Computing and Information Systems
Classical multi-echelon repairable item inventory models are based either on steady-state analysis or infinite repair capacity, which may not work well in situations when the demand is nonstationary, or repair capacity is limited. In this paper, we propose an analytical model for evaluating system performance that works well under limited repair capacity and nonstationary demands. Following the METRIC methodology, we then develop an optimisation algorithm to solve the corrective maintenance problem in military logistics. Experimental results show that our approach yields good solutions efficiently. This work has also resulted in a software that has been field-tested by a military organisation.
Test For Infinite Variance In Stock Returns, Xian Ning Yan
Test For Infinite Variance In Stock Returns, Xian Ning Yan
Dissertations and Theses Collection (Open Access)
The existence of second order moment or the finite variance is a commonly used assumption in financial time series analysis. We examine the validation of this condition for main stock index return series by applying the extreme value theory. We compare the performances of the adaptive Hill's estimator and the Smith's estimator for the tail index using Monte Carlo simulations for both i.i.d data and dependent data. The simulation results show that the Hill's estimator with adaptive data-based truncation number performs better in both cases. It has not only smaller bias but also smaller MSE when the true tail index …
The Cross-Section Of Stock Return And Volatility, Hongchao Han
The Cross-Section Of Stock Return And Volatility, Hongchao Han
Dissertations and Theses Collection (Open Access)
There has been increasing research on the cross-sectional relation between stock return and volatility. Conclusions are, however, mixed, partially because volatility or variance is modeled or parameterized in various ways. This paper, by using the Jiang and Tian (2005)'s model-free method, estimates daily option implied volatility for all US individual stocks from 1996:01 to 2006:04, and then employs this information to extract monthly volatilities and their idiosyncratic parts for cross-sectional regression analyses. We follow the Fama and French (1992) cross-sectional regression procedure and show that each of the 4 monthly measures of change of total volatility, total volatility, expected idiosyncratic …
The Impact Of Credit Watch And Bond Rating Changes On Abnormal Stock Returns For Non-Usa Domiciled Corporations, Benjamin Boon Ching Ee
The Impact Of Credit Watch And Bond Rating Changes On Abnormal Stock Returns For Non-Usa Domiciled Corporations, Benjamin Boon Ching Ee
Dissertations and Theses Collection (Open Access)
In this paper, we investigate whether credit watches and bond rating changes issued by Moodys' and S&P Credit Rating Agencies provide significant new information to investors for Non-USA domiciled corporations. We also examine whether the stock related cumulative abnormal return (CAR) differs according to the classification of the country of domicile (emerging or developed) of the corporation, and varies by state of the local stock market during the time of the rating event.
We find that on average, negative credit watches as well as long term rating downgrades result in significant stock related CAR for Non-USA domiciled 4 corporations. However, …

Estimating The Dynamics Of Mutual Fund Alphas And Betas, Harry Mamaysky, Matthew Spiegel, Hong Zhang
Research Collection Lee Kong Chian School Of Business
This article develops a Kalman filter model to track dynamic mutual fund factor loadings. It then uses the estimates to analyze whether managers with market-timing ability can be identified ex ante. The primary findings are as follows: (i) Ordinary least squares (OLS) timing models produce false positives (nonzero alphas) at too high a rate with either daily or monthly data. In contrast, the Kalman filter model produces them at approximately the correct rate with monthly data; (ii) In monthly data, though the OLS models fail to detect any timing among fund managers, the Kalman filter does; (iii) The alpha and …
Probabilistic Sales Forecasting For Small And Medium-Size Business Operations, Randall E. Duran
Probabilistic Sales Forecasting For Small And Medium-Size Business Operations, Randall E. Duran
Research Collection School Of Computing and Information Systems
One of the most important aspects of operating a business is the forecasting of sales and allocation of resources to fulfill sales. Sales assessments are usually based on mental models that are not well defined, may be biased, and are difficult to refine and improve over time. Defining sales forecasting models for small- and medium-size business operations is especially difficult when the number of sales events is small but the revenue per sales event is large. This chapter reviews the challenges of sales forecasting in this environment and describes how incomplete and potentially suspect information can be used to produce …

Commercialization Of Science: A Longitudinal Study Of Knowledge Distance, Firm Capabilities, And The Structure Of Licensing Contracts, Reddi Kotha, Gerard George
Commercialization Of Science: A Longitudinal Study Of Knowledge Distance, Firm Capabilities, And The Structure Of Licensing Contracts, Reddi Kotha, Gerard George
Research Collection Lee Kong Chian School Of Business
Though the popularity of research on technology transfer offices (TTOs) has vastly increased, there is little empirical evidence of how the potential value for a technology is estimated and negotiated in a license. Limited qualitative work and empirical work (e.g., Owen-Smith, 2005) tap into the underlying decisions before a technology can be licensed. Consequently, we know very little on how a particular technology is valued and its impact on contract design. In this study, we analyze the content, design, and performance of 847 licensing contracts between university technology transfer offices and firms.
Situational Judgment Tests: A Review Of Recent Research, Filip Lievens, Helga Peeters, Eveline Schollaert
Situational Judgment Tests: A Review Of Recent Research, Filip Lievens, Helga Peeters, Eveline Schollaert
Research Collection Lee Kong Chian School Of Business
Purpose - The purpose of this paper is to give an empirically-based review of the strengths and weaknesses of situational judgment tests (SJTs).Design/methodology/approach - The features, history, and development of SJTs are discussed. Next, a computerized search (from 1990-2007) is conducted to retrieve empirical studies related to SJTs. The effectiveness of SJTs is discussed in terms of reliability, criterion-related validity, incremental validity, construct-related validity, utility, adverse impact, applicant perceptions, fakability, and susceptibility to practice and coaching effects.Findings - Strengths of SJTs are that they show criterion-related validity and incremental validity above cognitive ability and personality tests. SJTs have also less …
Values, Ideologies, And Frames Of Reference In Employment Relations, John W. Budd, Devasheesh P. Bhave
Values, Ideologies, And Frames Of Reference In Employment Relations, John W. Budd, Devasheesh P. Bhave
Research Collection Lee Kong Chian School Of Business
Employment relations—which form most of the 20th century was called industrial relations, and what some now call human resources and industrial relations—is a multidisciplinary field studying all aspects of work and the employment relationship (Ackers and Wilkinson, 2003; Budd, 2004; Kaufm an, 2004). A multidisciplinary approach means that competing values and assumptions underlie the analyses, policies, and practices of employment relations scholars, practitioners, and policymakers. Unfortunately, these underlying beliefs are often implicit rather than explicit, or, with the longstanding focus on how industrial relations processes work, sometimes ignored altogether. But understanding the employment relationship, corporate human resource management practices, labor …

Technological Change Management Strategies In Asian Small-Scale Businesses: Trends In Singapore, Thomas Menkhoff, Yue Wah Chay
Research Collection Lee Kong Chian School Of Business
Based on survey data on the change management behavior of Chinese small and medium sized enterprises (SMEs) in Singapore, the paper explores how small entrepreneurs are coping with the city-state's turbulent business environment, processes of technological advancement and accelerated change. Differences between so-called opportunistic entrepreneurs and small business ventures are examined. Conceptually, the paper is informed by theories of change management, strategic choice, entrepreneurship and Chinese business. Special emphasis is put on the identification of demographic characteristics of "technological change masters" in Singapore's small business sector so as to gain an understanding of both the dynamism and relative passivity of …

This study examined the human and social capital factors associated with higher post-succession firm performance in family enterprises in Singapore. We also investigated the moderating influence of the board of directors in terms of its service role as stewards of the enterprise. We found that a successor's industry experience and diversity of network ties were positively associated with firm performance and boards that focused their role as advisors to the successor enhanced post-succession firm performance.

Too Little Or Too Much? Untangling The Relationship Between Corporate Philanthropy And Corporate Financial Performance, Heli Wang, Jaepil Choi, Jiatao Li
Research Collection Lee Kong Chian School Of Business
What is the relationship between corporate philanthropy and corporate financial performance? Some scholars argue that corporate philanthropy facilitates stakeholder cooperation and helps secure access to critical resources controlled by those stakeholders, suggesting that corporate philanthropy should be positively associated with corporate financial performance. In contrast, other scholars take a negative stance, suggesting that corporate philanthropy diverts valuable corporate resources and tends to inhibit corporate financial performance. Existing empirical studies have not found conclusive evidence on the corporate philanthropy-financial performance relationship. Integrating and extending existing perspectives, this study develops the argument that the relationship between corporate philanthropy and financial performance is …

Retirement systems are increasingly asked to do an ever-better job of enhancing the performance of pension investments. The Singaporean Central Provident Fund permits pension system participants to keep their money in a government-run investment pool, or if they wish, they may select professionally managed unit trusts for their retirement accumulations. Opting for investment choice also exposes members to additional investment costs not charged by the government-managed account. This paper explores the charges levied by the private fund managers and we show that foreign ownership, active style of management and equity/balanced funds tend to be most expensive. We conclude with a …
