Robust Temporal Constraint Networks, Hoong Chuin Lau, Thomas Ou, Melvyn Sim

Research Collection School Of Computing and Information Systems

In this paper, we propose the Robust Temporal Constraint Network (RTCN) model for simple temporal constraint networks where activity durations are bounded by random variables. The problem is to determine whether such temporal network can be executed with failure probability less than a given 0 ≤ E ≤ 1 for each possible instantiation of the random variables, and if so. how one might find a feasible schedule with each given instantiation. The advantage of our model is that one can vary the value of ∊ to control the level of conservativeness of the solution. We present a computationally tractable and …

Bank Lending And Real Estate In Asia: Market Optimism And Asset Bubbles, Winston T. H. Koh, Roberto S. Mariano, Andrey Pavlov, Sock-Yong Phang, Augustine H. H. Tan, Susan M. Wachter

Research Collection School Of Economics

This paper investigates the Asian real estate price run-up and collapse in the 1990s. We identify financial intermediaries’ underpricing of the put option imbedded in non-recourse mortgage loans as a potential cause for the observed price behavior. This underpricing is due to behavioral causes (lender optimism and disaster myopia) and/or rational response of lenders to market incentives (agency conflicts, deposit insurance, or limited liability of bank shareholders). The empirical evidence suggests that underpricing occurred in Thailand, Malaysia, and Indonesia. Consequently, these countries experienced a more severe market crash than Hong Kong and Singapore, where underpricing was kept under control by …

The Role Of Analysts’ Forecasts In Accounting-Based Valuation: A Critical Evaluation, Qiang Cheng

Research Collection School Of Accountancy

This paper critically evaluates the use of analysts forecasts in accounting-based valuation. Specifically, I assess the usefulness and the limitation of analysts forecasts in predicting future earnings and in explaining the market-to-book ratio, in light of a comprehensive set of 22 explicit information items, including: economic rent proxies, conservative accounting proxies, earnings quality signals, transitory earnings proxies, industry characteristics, and risk and growth proxies. While analysts forecasts capture 45–83% of the information from these sources depending on model specifications, they do not appear to fully incorporate certain information items. In particular, proxies for conservative accounting and transitory earnings are incrementally …

Education, Technological Progress And Economic Growth, Winston T. H. Koh, Hing-Man Leung

Research Collection School Of Economics

An important role of education – and the resultant accumulation of human capital – for a less-developed economy is to facilitate technology diffusion in order for it to catch up with developed economies. This paper presents a model linking education, the accumulation of physical capital and technological progress. In the model, investment in education and the accumulation of physical capital are complementary, and intertwine with the technology progress through related effects on technology diffusion and the expansion of the technology frontier. The allocation of effort to education, the optimal savings rate and the technology gap are endogenously determined in the …

The Effects Of Sfas 131 Geographic Segment Disclosures On The Valuation Of Foreign Earnings, Ole-Kristian Hope, Tony Kang, Wayne Thomas, Florin Vasvari

Research Collection School Of Accountancy

Foreign operations are becoming increasingly important for U.S. companies. We investigate whether the market’s valuation of foreign earnings is a function of the firm’s geographic segment disclosures. Specifically, we examine the effects of an increase in the number of geographic segments disclosed and the inclusion of earnings measures in geographic segment disclosures following the adoption of SFAS 131. We find strong evidence that our proxies for increased disclosure are positively associated with the valuation of foreign earnings. Our results are robust to a number of sensitivity analyses. Taken together, our results suggest that the pricing of foreign earnings is associated …

Selecting Employees For Global Assignments: Can Assessment Centers Measure Cultural Intelligence?, Michael M. Harris, Filip Lievens

Research Collection Lee Kong Chian School Of Business

Our field is replete with attempts to measure and predict a variety of behaviors in the workplace, including task performance, contextual performance, counterproductive activity, to name but a few. One of the most recent types of behavior that organizations would like to predict is the ability to interact effectively with culturally-dissimilar others. Known by various names, including cultural intelligence or cultural adaptability, there is relatively little research as of yet regarding this topic. Nevertheless, given the growing recognition that the workplace increasingly operates in a global fashion, there is reason to believe that the literature regarding this topic will expand. …

The Effects Of Shilling On Final Bid Prices In Online Auctions, Robert J. Kauffman, Charles A. Wood

Research Collection School Of Computing and Information Systems

An increasing number of reports of online auction fraud are of growing concern to auction operators and participants. In this research, we discuss reserve price shilling, where a bidder shills in order to avoid paying auction house fees, rather than to drive up the price of the final bid. We examine the effect that premium bids have upon the final selling price, since they are linked with reserve price shill bids. We use 10,260 eBay auctions during April 2001, and identify 919 auctions involving 322 sellers and 1583 bidders involved in concurrent auctions for the exact same item. We find …

Technology Competition And Optimal Investment Timing: A Real Options Perspective, Robert J. Kauffman, X. Li

Research Collection School Of Computing and Information Systems

Companies often choose to defer irreversible investments to maintain valuable managerial flexibility in an uncertain world. For some technology-intensive projects, technology uncertainty plays a dominant role in affecting investment timing. This article analyzes the investment timing strategy for a firm that is deciding about whether to adopt one or the other of two incompatible and competing technologies.We develop a continuous-time stochastic model that aids in the determination of optimal timing for managerial adoption within the framework of real options theory. The model captures the elements of the decision-making process in such a way so as to provide managerial guidance in …

The Creation And Economic Regulation Of Housing Markets: A Comparison Of The Experiences Of Singapore And Korea, Sock-Yong Phang

Research Collection School Of Economics

Privatization, creation of markets and economic regulation are terms that few would immediately associate with the housing sector. Mainstream housing markets in most of the free market economies of the developed world are regarded as competitive markets, with little need for economic regulation of the market. Regulations that attempt to control behavior directly are generally limited to policies relating to rent control, the provision of rental housing or rental allowances for lower income groups, as well as land use regulations and building controls.

The housing sectors of Singapore and Korea are highly unusual in the extent of government involvement and …

Regional Co-Operation And Low-Cost Investment Enclaves: An Empirical Study Of Singapore's Industrial Parks In Riau, Indonesia, Caroline Yeoh, Darren Lim, Adeline Kwan

Research Collection Lee Kong Chian School Of Business

Infrastructure can be unreliable and administration subject to corruption in Asia's rapidly developing economies. Foreign investment is thus drawn to privileged investment enclaves, as well as in and around centers of international infrastructure. This context provides opportunity for Singapore-styled industrial parks, through the provision of superior infrastructure, the ability to negotiate investment concessions at inter-government level and, where existing, through the links to influential Chinese business groups in the investment location. Batamindo Industrial Park and Bintan Industrial Estate in Indonesia were the prototypes. This paper revisits the Parks, and offers a stock-take on the challenges confronting these flagship projects. Evidence …

Regionalisation And Singapore's Transborder Industrialisation: A New Perspective On Suzhou Industrial Park, Xun Cai, Lu Gao, Caroline Yeoh

Research Collection Lee Kong Chian School Of Business

The dynamics of international economic competition have prompted governments to re-examine accustomed policies, and search for alternative strategies, in order to re-position their economies for the future. This paper takes a look at Singapore’s search for a competitive positioning in the global marketplace, and focuses on the city-state’s much-publicized, and controversial, flagship project in China, viz, the Suzhou Industrial Park (SIP). This strategic initiative is premised on the perceptions that Singapore’s positive reputation with multinational corporations, and ‘guanxi’ (or connections) with regional governments, will give the regional sites a strategic advantage in the competition for foreign investments. Earlier studies have …

Strategic Management For Economic Development: Remaking The Singapore 'Model', Caroline Yeoh, Wilfred Pow Ngee How

Research Collection Lee Kong Chian School Of Business

The dynamics of international economic competition have far-reaching policy implications for both developing and developed countries. Established industrial and trade policy regimes in most countries are under tremendous strain, and this applies even to the dynamic Newly Industrialising Economies (NIEs). The outward-oriented development strategies of the Asian NIEs, which once seemed unbeatable, have run up against protectionist barriers in the developed countries, and increasingly, against competitive pressures from other up and coming developing countries. Governments in these NIEs have had to re-examine accustomed policies and strategies, and search for alternative strategies and programs, in order to re-position their economies for …

The Perceptions Of Students Outside The United States On Cases Versus Lectures, G.W. Kester, R.A. Dean, David K. Ding, S.A. Hoover, M. Skully

Domestic And Foreign Earnings, Stock Return Variability, And The Impact Of Investor Sophistication, Dan Segal, Jeffrey L. Callen, Ole-Kristian Hope

Research Collection School Of Accountancy

We examine the importance of foreign earnings relative to domestic earnings for a sample of U.S. multinationals using variance decomposition. Our methodology represents an alternative and complementary approach over the prior literature, which is based on traditional regressions and earnings response coefficients. We document that domestic earnings are more important in explaining the variance of unexpected returns than are foreign earnings and that the relative importance of domestic earnings is a decreasing function of investor sophistication. Last, we classify institutional investors as either short- or long-term oriented following Bushee [1998]. We find that the variance contribution of foreign earnings increases …

Ownership Structure, Investment Behaviour And Firm Performance In Japanese Manufacturing Industries, Eric Gedajlovic, Toru Yoshikawa, Motomi Hashimoto

Research Collection Lee Kong Chian School Of Business

Using data spanning the 1996-98 fiscal years of 247 of Japan's largest manufacturers, we empirically evaluate the extent to which a firm's investment behaviour and financial performance are influenced by its ownership structure. To do so, we examine six distinct categories of Japanese shareholders: foreign investors, investment funds, pension funds, banks and insurance companies, affiliated companies and insiders. Our findings strongly indicate that the relationship between the equity stakes of a particular category of investor and a firm' s financial performance and investment behaviour is considerably more complex than is depicted in simple principal-agent representations. Such a result emphasizes the …

Theorizing, Measuring, And Predicting Knowledge Sharing Behavior In Organizations - A Social Capital Approach, Chay Yue Wah, Thomas Menkhoff, Benjamin Loh, Hans-Dieter Evers

Research Collection Lee Kong Chian School Of Business

This study aims to understand the social and organizational factors that influence knowledge sharing. A model of knowledge management and knowledge sharing was developed inspired by the work of Nahapiet and Ghoshal. Data on demographics and various social capital measures were collected from a sample of members of a tertiary educational institution in Singapore in 2003. Reward & recognition, open-mindedness and cost concerns of knowledge hoarding turned out to be the strongest predictors of knowledge sharing rather than pro-social motives or organizational concern. Overall, the findings provide evidence for the importance of a conducive organizational climate and state-of-the art performance …

Rhythms Of Life: Antecedents And Outcomes Of Work-Family Balance In Employed Parents, Samuel Aryee, E. S. Srinivas, Hwee Hoon Tan

Research Collection Lee Kong Chian School Of Business

This study examined antecedents and outcomes of a fourfold taxonomy of work-family balance in terms of the direction of influence (work-family vs. family-work) and type of effect (conflict vs. facilitation). Respondents were full-time employed parents in India. Confirmatory factor analysis results provided evidence for the discriminant validity of M. R. Frone' s (2003) fourfold taxonomy of work-family balance. Results of moderated regression analysis revealed that different processes underlie the conflict and facilitation components. Furthermore, gender had only a limited moderating influence on the relationships between the antecedents and the components of work-family balance. Last, work-family facilitation was related to the …

Politico-Economic Factors Associated With Interest In Starting A Business: A Multi-Country Study, Thomas Begley, Wee Liang Tan, Herbert Schoch

Research Collection Lee Kong Chian School Of Business

Public health is a legal term of art referring specifically to delineated powers, duties, rights, and responsibilities. An emerging human rights conception of public health justifies government intervention. Intervention involves public officials taking appropriate measures including environmental regulations pursuant to specific legal authority, after balancing private rights and public interests, to protect the health of the public. This article is a critical analysis of the performance of the actors in maintaining environmental standards in India. Part II is a discussion on the source of environmental law in India. Part III discusses the performance of the legislature. Part IV evaluates the …

What Determines Residual Income?, Qiang Cheng

Research Collection School Of Accountancy

This paper investigates the determinants of residual income scaled by book value of equity, i.e., abnormal return on equity (ROE), by analyzing the impact of value-creation (economic rents) and value-recording (conservative accounting) processes on abnormal ROE. I rely on economic theories to characterize economic rents and develop an empirical measure—the conservative accounting factor—to capture the effect of conservative accounting. As expected, industry abnormal ROE increases with industry concentration, industry-level barriers to entry, and industry conservative accounting factors. Also as expected, the difference between firm and industry abnormal ROE increases with market share, firm size, firm-level barriers to entry, and firm …

Equity Incentives And Earnings Management, Qiang Cheng, Terry Warfield

Research Collection School Of Accountancy

This paper examines the link between managers' equity incentives—arising from stock-based compensation and stock ownership—and earnings management. We hypothesize that managers with high equity incentives are more likely to sell shares in the future and this motivates these managers to engage in earnings management to increase the value of the shares to be sold. Using stock-based compensation and stock ownership data over the 1993–2000 time period, we document that managers with high equity incentives sell more shares in subsequent periods. As expected, we find that managers with high equity incentives are more likely to report earnings that meet or just …

Understanding Business Group Performance In An Emerging Economy: Acquiring Resources And Capabilities In Order To Prosper, Daphne W. Yiu, Garry D. Bruton, Yuan Lu

Research Collection Lee Kong Chian School Of Business

The prevalent organizational form in most emerging markets is business groups. These groups have typically been viewed through a transaction cost economics perspective where they are perceived as responses to inefficiencies in the market. However, the evidence to date on what generates a positive business group-performance relationship in such environments is not well understood. This study expands the understanding of business groups by employing the resource-based and institutional theoretical perspectives to examine how groups acquire resources and capabilities to prosper. The empirical evidence is based on over 224 business groups in the emerging economy context of China and shows that …

Assessment Centers: Recent Developments In Practice And Research, Filip Lievens, George C. Thornton Iii

Research Collection Lee Kong Chian School Of Business

In an assessment center, candidates who participate in various simulation exercises are evaluated by a multiple trained assessors on job-related dimensions. Examples of commonly used simulation exercises are role-plays, presentations, in-baskets, or group discussions. For nearly fifty years, assessment centers have remained a popular approach for managerial selection and development (Spychalski, Quinones, Gaugler, & Pohley, 1997), and they have been shown to have substantial validity (Thornton & Rupp, 2004). Assessment centers are also very much an international affair as they are used around the globe (Byham, 2001; Kudisch, Avis, Fallon, Thibodeaux, Roberts, Rollier, & Rotolo, 2001; Sarges, 2001). Over the …

Smooth Test For Density, Aurobindo Ghosh, Anil K Bera

Research Collection Lee Kong Chian School Of Business

Recently econometricians have shifted their attention from point and interval forecasts to density forecasts because at the heart of market risk measurement is the forecast of the probability density functions of various financial variables. In this paper, we propose a formal test for density forecast evaluation based on Neyman's smooth test procedure. Apart from accepting or rejecting the tested model, this approach provides specific sources (such as the location, scale and shape of the distribution) of rejection, thereby helping in deciding possible modifications of the assumed model. Our applications to S&P 500 returns indicate capturing time-varying volatility and non-gaussianity significantly …

Partnering For Perfection: An Economics Perspective On B2b Electronic Market Strategic Alliances, Qizhi Dai, Robert J. Kauffman

Research Collection School Of Computing and Information Systems

New technological innovations have made it possible for new intermediaries to create value in business processes that involve the procurement of manufacturing and services supplies. Associated with these innovations is the emergence of business-to-business (B2B) electronic markets. These act as digital intermediaries that aim to reduce the transaction costs and mitigate the risks inherent in procurement. They improve buyers’ capabilities to search for attractive prices and also serve to increase the liquidity of sellers’ products. In this chapter, the authors explore the evolution of B2B e-market firms in terms of the strategies they employ to “perfect” their value propositions and …
