Cross Sectional Variation Of The Effect Of Bond Rating Changes On Stock Prices, Jeremy C. Goh, Louis H. Ederington Jan 1999

Cross Sectional Variation Of The Effect Of Bond Rating Changes On Stock Prices, Jeremy C. Goh, Louis H. Ederington

Research Collection Lee Kong Chian School Of Business

Previous research has found that the stock market reacts negatively to bond rating downgrades and that downgrades tend to follow periods of negative returns, indicating that at least some downgrades are partially predictable. Hypothesizing that the reaction to a downgrade depends on both the implications for cash flows and the degree of surprise, we explore how the reaction to downgrade announcements varies across bond issues. We find that the equity market reacts much more negatively to bond rating downgrades to and within the speculative bond category than to downgrades within the investment grade category. Within the speculative category, the reaction …


Long Memory And Asia Crisis: Implication For Capital Controls And Management, Kuo Chuen David Lee Jan 1999

Long Memory And Asia Crisis: Implication For Capital Controls And Management, Kuo Chuen David Lee

“Financial markets are given to excesses and if a boom/bust sequence progresses beyond a certain point, it will never revert to where it came from. Instead of acting like a pendulum, financial markets have recently acted more like a wrecking ball, knocking over one economy after another.” - A testimony before the US House Banking Committee, Sep, 1998. There are three parts to this paper. The first part examines the time series behaviour of the equity indices of ten countries. Using Robinson (1995a)’s modified GPH estimator and Robinson (1994a)’s average periodogram estimator for the differencing parameter, we have detected that …


A Classification Scheme For Project Scheduling Problems, Willy Herroelen, Erik Demeulemeester, Bert De Reyck Jan 1999

A Classification Scheme For Project Scheduling Problems, Willy Herroelen, Erik Demeulemeester, Bert De Reyck

Research Collection Lee Kong Chian School Of Business

The basic concern of scheduling is commonly described as the allocation of limited resources to tasks over time (Lawler et al. 1993, Pinedo 1995). The resources and tasks may take many forms. In project scheduling the tasks refer to the activities belonging to one or more projects. The execution of project activities may require the use of different types of resources (money, crews, equipment, …). The scheduling objectives may also take many forms (minimizing project duration, minimizing project costs, maximizing project revenues, optimizing due date performance,…). The result is a wide and steadily growing variety of problem types which motivates …


Doing Academic Work, Stephen Matthias Harney, Frederick Moten Jan 1999

Doing Academic Work, Stephen Matthias Harney, Frederick Moten

Research Collection Lee Kong Chian School Of Business

When professors get together outside the university they talk about that thing which dominates them, their work. This conversation may take the form of discussing a product of that work-a lecture in class, a research paper, committee deliberations-but most often it seems to be about conditions of work. One hears talk about course load, the trials of tenure and promotion, salaries and compensation, and of course the quality of the students on which some of academic labor is supposed to fall. In themselves, these conversations are not surprising. Mail carriers have very similar conversations, as do primary school teachers, subway …


Theory And Research In Strategic Management: Swings Of A Pendulum, Robert E. Hoskisson, Michael A. Hitt, William P. Wan, Daphne W. Yiu Jan 1999

Theory And Research In Strategic Management: Swings Of A Pendulum, Robert E. Hoskisson, Michael A. Hitt, William P. Wan, Daphne W. Yiu

Research Collection Lee Kong Chian School Of Business

The development of the field of strategic management within the last two decades has been dramatic. While its roots have been in a more applied area, often referred to as business policy, the current field of strategic management is strongly, theory, based with substantial empirical research, and is eclectic in nature. This review of the development of the field and its current position examines the field's early development and the primary theoretical and methodological bases through its history. Early developments include Chandler's (1962) Strategy and Structure and Ansoff's (1965) Corporate Strategy. These early works rook on a contingency perspective (fit …


Phase Transitions In Project Scheduling, Willy Herroelen, Bert De Reyck Jan 1999

Phase Transitions In Project Scheduling, Willy Herroelen, Bert De Reyck

Research Collection Lee Kong Chian School Of Business

Researchers in the area of artificial intelligence have recently shown that many NP-complete problems exhibit phase transitions. Often, problem instances change from being easy to being hard to solve to again being easy to solve when certain of their characteristics are modified. Most often the transitions are sharp, but sometimes they are rather continuous in the order parameters that are characteristic of the system as a whole. To the best of our knowledge, no evidence has been provided so far that similar phase transitions occur in NP-hard scheduling problems. In this paper we report on the existence of phase transitions …


Local Coherence And Its Limits: A Second Look At Second Sentences, Desmond Allison, Susheela Varghese, Siew Mei Wu Jan 1999

Local Coherence And Its Limits: A Second Look At Second Sentences, Desmond Allison, Susheela Varghese, Siew Mei Wu

Research Collection Lee Kong Chian School Of Business

Our article takes up Joy Reid's (1996) proposal that second sentences deserve a second look in academic writing research and pedagogy. Reid's data and commentaries indicate that second sentences, the sentences following topic sentences, make important but generally underrated contributions to the (in)coherence of students' written paragraphs. Her study, in a U.S. university, found that English as a second language (ESL) student writers often developed paragraphs that did not meet the expectations of experienced native English speaker (NES) readers. We offer a contextualized critique and partial replication of Reid's exploratory study. Our research, in Singapore, investigates second sentence writing by …


Algorithms For Scheduling Projects With Generalized Precedence Relations, Bert De Reyck, Erik Demeulemeester, Willy Herroelen Jan 1999

Algorithms For Scheduling Projects With Generalized Precedence Relations, Bert De Reyck, Erik Demeulemeester, Willy Herroelen

Research Collection Lee Kong Chian School Of Business

The problem of scheduling projects under various types of resource constraints constitutes an important and challenging problem which has received increasing attention during the past several years. The bulk of the models and procedures designed for coping with these problem types aim at scheduling project activities to minimize the project duration subject to constant availability constraints on the required set of resources and precedence constraints that indicate that activities can only be started when all of their predecessors have already been finished. However, real-life project scheduling applications often involve more complicated types of precedence relations such as arbitrary minimal and …


Marketing, Business Processes, And Shareholder Value: An Organizationally Embedded View Of Marketing Activities And The Discipline Of Marketing, Rajendra Kumar Srivastava, Tasadduq A. Shervani, Liam Fahey Jan 1999

Marketing, Business Processes, And Shareholder Value: An Organizationally Embedded View Of Marketing Activities And The Discipline Of Marketing, Rajendra Kumar Srivastava, Tasadduq A. Shervani, Liam Fahey

Research Collection Lee Kong Chian School Of Business

The authors develop a framework for understanding the integration of marketing with business processes and shareholder value. The framework redefines marketing phenomena as embedded in three core business processes that generate value for customers-product development management, supply chain management, and customer relationship management-which in turn creates shareholder value. Such a conceptualization of marketing has the potential to introduce dramatic shifts in the scope, content, and influence of marketing in the organization. The authors highlight the implications of an organizationally embedded view of marketing for the future of marketing theory and practice.

It is well known that foreign investments by the industrialized world are driven by the private sector leveraging its technological, management and marketing skills, and that those by developing countries arise because of geographic proximity, social and economic homogeneity, and cultural familiarity. In the case of Singapore, a uniques characteristics is the direct participation by government-related corporations and their affiliates, and persuasion by statutory bodies such as the Economic Development Board and Trade Development Board for the corporate sector


East Vs. West: Strategic Marketing Management Meets The Asian Networks, George T. Haley, Chin Tiong Tan Jan 1999

East Vs. West: Strategic Marketing Management Meets The Asian Networks, George T. Haley, Chin Tiong Tan

Research Collection Lee Kong Chian School Of Business

Strategic management in Asia is different. Decision-making differs from that taught in Western, and even Asian, schools of business. In the last decade, the influence of Japanese management systems on Western management practice has become evident. Though the Japanese economy is the world's second largest, and Japan's population substantial, neither compares with the combined economies and combined populations of non-Japanese Asia. The influence of the most aggressive elements of the non-Japanese Asian business communities, the Overseas Chinese and Overseas Indian Networks cannot help to be felt on Western management practice. This article explains why this difference in decision-making styles exists, …
