A Remanufacturing News-Vendor With Pricing And Take-Back Pricing, Keyu Lu

Dissertations and Theses Collection (Open Access)

This paper analyzes the problem of a remanufacturing news-vendor with selling and take-back price decision. In our model, the remanufacturer decides selling price, take-back price, and order quantity for new materials. She then uses the stochastic take-back quantity and the new material to meet the stochastic demand comparably to a news vendor setting. We allow demand and take-back supply to be correlated. In this thesis, we study a production problem with dual input sources: raw materials and recycled or remanufactured take-back items. To answer when mixed-sourcing is best, we analyze the model under deterministic setting first, provide criteria for different …

Service Innovation In The Non-Profit Sector, Gabriel Boon Siong Lim

Dissertations and Theses Collection (Open Access)

Non-profit organisations are valued because they provide services that address unmet needs. Nonprofits who engage in social entrepreneurship augment their contributions through new services, programmes, enterprises and revenue generated. It is not surprising, therefore, for policy makers to encourage social entrepreneurship, service innovations and social enterprises. However, not all nonprofits seek to innovate by creating revenue-generating social enterprises. They may continue to devote themselves to specific fields and existing practices through other forms of service innovations instead. The intent of nonprofits in starting new services is investigated through a two-pronged quantitative and qualitative research approach.

In the quantitative section, a …

How Predictable Is The Chinese Stock Market?, Fuwei Jiang

Dissertations and Theses Collection (Open Access)

We analyze return predictability for the Chinese stock market, including the aggregate market portfolio and the components of the aggregate market, such as portfolios sorted on industry, size, book-to-market and ownership concentration. Considering a variety of economic variables as predictors, both in-sample and out-of-sample tests highlight significant predictability in the aggregate market portfolio of the Chinese stock market and substantial differences in return predictability across components. Among industry portfolios, Finance and insurance, Real estate, and Service exhibit the most predictability, while portfolios of small-cap and low ownership concentration firms also display considerable predictability. Two key findings provide economic explanations for …

Aircraft Leasing With Contracts, Qiong Zuo

Dissertations and Theses Collection (Open Access)

We study a problem of rental rate pricing and rental contract designing in aircraft leasing industry. In a framework of Stackelberg game, the system is composed of an airline company (carrier) and an aircraft leasing company (lessor). Acting as the leader, the lessor announces daily rental rates and/or provides long-term contracts on a finite horizon with multiple periods. For each period, the carrier determines the aircraft leasing number to adjust the flight capacity, and applies a dynamic pricing policy for air-tickets based on a seasonally stochastic demand and some economic factor, such as oil price. We find the optimal policies …

Discounts And Termination Of Close-End Funds, Chen Chen

Dissertations and Theses Collection (Open Access)

Based on an extensive sample of U.S. closed end funds undergoing termination, this study offers a comprehensive analysis of closed end fund exiting behaviors. There are four ways for a fund to exit: merger into other closed-end fund, liquidation, conversion to open-end mutual fund and merger into open-end mutual fund. Closed-end funds that exit must choose the most efficient and optimal mechanisms corresponding to funds‟ characteristics and organizational forms. In this study, I find that closed-end funds exit optimally. First, funds with persistently larger discount and smaller size are more likely to exit and consistent with rational expectation, market incorporates …

Short-Selling Prior To Analyst Recommendations, Can Qu

Dissertations and Theses Collection (Open Access)

This paper investigates short-selling five days prior to analyst recommendations by using a complete data set from Reg SHO database during January, 2005 to July, 2007. Empirical tests uncover the evidence that short-sellers significantly increase their short positions prior to negative analyst recommendations, which is consistent with the informed trading hypothesis. This finding is robust to model specification. Further, this paper also examines which of the two competing hypotheses-prediction and tipping-could better explain short-sellers’ informative front-running. The tests indicate that short-sellers use book-to-market ratio as a filter to narrow down their pool of candidates, while market capitalization doesn’t play a …

Applying Soft Cluster Analysis Techniques To Customer Interaction Information, Randall E. Duran, Li Zhang, Tom Hayhurst

Research Collection School Of Computing and Information Systems

The number of channels available for companies and customers to communicate with one another has increased dramatically over the past several decades. Although some market segmentation efforts utilize high-level customer interaction statistics, in-depth information regarding customers’ use of different communication channels is often ignored. Detailed customer interaction information can help companies improve the way that they market to customers by taking into consideration customers’ behaviour patterns and preferences. However, a key challenge of interpreting customer contact information is that many channels have only been in existence for a relatively short period of time, and thus, there is limited understanding and …

The Monetary Value Of Virtual Goods: An Exploratory Study In Mmorpgs, Qiu-Hong Wang, Viktor Mayer-Schonberger

Research Collection School Of Computing and Information Systems

This study investigates the monetary value of time spent in virtual worlds in the context of 24 most popular MMORPGs Building on classic economic theory, we approach this issue through a combination of theoretical modeling, experiment, and cross-sectional time series data analysis. Our findings suggest that intensive social networking and flatter social hierarchy structures are associated with lower monetary value of time spent in-game. Further, two opposite network effects on the monetary value of in-game time spent were observed. One is the positive network effect from the active user base, the other is the negative network effect from the intensity …

Tunneling As An Incentive For Earnings Management During The Ipo Process In China, Jiwei Wang, Joseph Aharony, Hongqi Yuan

Research Collection School Of Accountancy

Using a sample of 185 Chinese IPO firms listed on the Shanghai Stock Exchange during the period 1999-2001, we show that related-party (RP) sales of goods and services could be used opportunistically to manage earnings upwards in the pre-IPO period. We also provide evidence that such behavior may be motivated by the prospect of tunneling opportunities in the post-IPO period, i.e., exploiting economic resources from minority shareholders for the benefit of the parent company. We provide evidence of one such opportunistic tunneling tool: non-repayment by Chinese parent companies of net outstanding corporate loans made to them by their newly listed …

Hong Kong’S New Creative Industries: The Example Of The Video Games Sector, F. Ted Tschang

Research Collection Lee Kong Chian School Of Business

Hong Kong has considerable creative and entrepreneurial resources, and the opportunity to build a vibrant set of creative industries, including in the new sectors such as video games, animation, and computer graphics. However, as it stands, some of these industries, especially that of the games industry, are fledgling in nature. Strong supporting institutions already exist, but it is essential to discover how industry can be better supported with existing and new resources — financial and otherwise. The opportunities are immense, but so is the competition. The new entertainment media sectors are growing at a faster pace than most economic sectors …

Trust Differences Across National-Societal Cultures: Much To Do, Or Much Ado About Nothing?, Don Ferrin, Nicole Gillespie

Research Collection Lee Kong Chian School Of Business

Does trust and its development, functions and meaning, differ between people from different national–societal cultures? There is considerable anecdotal evidence and some theoretical argumentation to suggest it does, but are these supported by empirical research? This chapter reviews the available empirical evidence on the effects of national–societal culture on interpersonal trust. It focuses largely on quantitative empirical evidence to consider the extent to which, and the ways in which, interpersonal trust differs across national–societal cultures. In every category of our review we found evidence of cross-cultural differences, particularly on generalized trust, and also evidence of trust universals across cultures. In …

The Employment Relationship, John W. Budd, Devasheesh P. Bhave

Research Collection Lee Kong Chian School Of Business

The employment relationship is the connection between employees and employers through which individuals sell their labor. This might consist of an immigrant day laborer paid by the bushel to pick fruit in the hot sun, a salaried manager who has been working in an air-conditioned office for the same company for 40 years, or innumerable other situations. Irrespective of situation, all employees and employers have fundamental interests they pursue through the employment relationship, all forms of this relationship are mediated by labor markets and states, and each instance of this relationship is governed by some form of a contract, ranging …

Effective Project Planning: Making The Most Of Project Planning Tools, Bert De Reyck

Research Collection Lee Kong Chian School Of Business

Although project planning tools such as Microsoft Project and Primavera have become indispensable tools for supporting the project planning process in a wide variety of industries and organizations, many companies do not use these tools in the best possible way, resulting in disappointment and frustration as well as a lack of effective project management support. In this article, we propose several guidelines on what to do,

Knowledge Clusters And Knowledge Hubs: Designing Epistemic Landscapes For Development, Hans-Dieter Evers, Solvay Gerke, Thomas Menkhoff

Research Collection Lee Kong Chian School Of Business

Purpose – With globalization and knowledge-based production, firms may cooperate on a global scale, outsource parts of their administrative or productive units and negate location altogether. The extremely low transaction costs of data, information and knowledge seem to invalidate the theory of agglomeration and the spatial clustering of firms, going back to the classical work by Alfred Weber and Alfred Marshall, who emphasized the microeconomic benefits of industrial collocation. This paper aims to argue against this view and show why the growth of knowledge societies will rather increase than decrease the relevance of location by creating knowledge clusters and knowledge …

Nested Coloured Timed Petri Nets For Production Configuration Of Product Families, Lianfeng Zhang, Brian Rodrigues

Research Collection Lee Kong Chian School Of Business

Production configuration is as an effective technique to deal with product variety while maintaining production stability and efficiency. It involves a diverse set of process elements (e.g., machines, operations), a high variety of component parts and assemblies and many constraints arising from product and process variety. Production configuration entails the selection and subsequent arrangement of process elements into complete production processes and the final evaluation of configured multiple alternatives. To better understand production configuration and its implementation, we study the underlying logic for configuring production processes using a dynamic modelling and visualisation approach. This is accomplished by developing a new …

Evaluating The Impact Of The Un Convention On The Use Of Electronic Communications In International Contracts On Domestic Contract Law: The Singapore Example, Eliza Mik

Research Collection Yong Pung How School Of Law

The United Nations Commission on International Trade Law (UNCITRAL) Convention on the Use of Electronic Communications in International Contracts (CUECIC or Convention) was adopted on 23 November 2005. Its essential objective is to establish uniform rules intended to “remove obstacles to the use of electronic communications in international contracts, including obstacles that might result from the operation of existing international trade law instruments, with a view to enhancing legal certainty and commercial predictability.” The Convention relies on the UNCITRAL Model Law on Electronic Commerce (MLEC), which constitutes an e-commerce flagship project dating back to 1995. It also resembles UNCITRAL’s Convention …

Are Family Firms More Tax Aggressive Than Non-Family Firms?, Shuping Chen, Xia Chen, Qiang Cheng, Terry Shevlin

Research Collection School Of Accountancy

Taxes represent a significant cost to the firm and shareholders, and it is generally expected that shareholders prefer tax aggressiveness. However, this argument ignores potential non-tax costs that can accompany tax aggressiveness, especially those arising from agency problems. Firms owned/run by founding family members are characterized by a unique agency conflict between dominant and small shareholders. Using multiple measures to capture tax aggressiveness and founding family presence, we find that family firms are less tax aggressive than their non-family counterparts, ceteris paribus. This result suggests that family owners are willing to forgo tax benefits to avoid the non-tax cost of …

Why "Democracy" And "Drifter" Firms Can Have Abnormal Returns: The Joint Importance Of Corporate Governance And Abnormal Accruals In Separating Winners From Losers, Koon Boon Kee

Dissertations and Theses Collection (Open Access)

Do managers exercise accounting discretion in an opportunistic or efficient manner? Good governance structures, which mitigate agency costs, are necessary to ensure that the accounting information supplied by management is not opportunistically manipulated. The output of quality accounting information, in turn, serves as an input to better governance structures. Thus, governance and earnings quality (EQ) are inexorably linked through a complementarity relationship. This suggests two previously unexamined relationships. Firstly, the governance effects on performance in the influential paper by Gompers, Ishii and Metrick (2003) is overrated without good EQ, measured by the magnitude of abnormal accruals (AA), as an input. …

Why Does Corporate Governance Matter? Evidence From Seasoned Bond Offerings, Fang Wang

Dissertations and Theses Collection (Open Access)

To examine the importance of corporate governance, I look at how management and investors behave in the event of seasoned bond offerings, controlling for the corporate governance structure of issuing firms. I find that companies with the weakest governance structure aggressively manipulate their earnings upwards during the two years prior to the debt issuances. And when the bond offerings are announced to the market, these same firms experienced positive abnormal returns over a three day event period, indicating that investors of poorly governed firms value a debt financing for the alleged decrease in agency cost.

Does Corporate Governance Matter, Evidence From Earnings Management Practices In Singapore, Lingxu Hu

Dissertations and Theses Collection (Open Access)

This paper addresses two questions. First, do good corporate governance practices add values to company or does it lead to higher stock returns in Singapore? Second, does poorly governed listed company in SGX tend to manage their earnings by using discretionary accruals? Following the approach of Gompers et al. (2003), we formed two portfolios consisting of well-governed and poorly governed companies. Well governed companies are able to maintain a higher return relative to poorly governed companies. I also look at the firm valuation from the adoption of corporate governance practices. Our result shows a positive relationship between firm valuation and …

News Which Moves The Market: Assessing The Impact Of Published Financial News On The Stock Market, Yu Chiang Soon

Dissertations and Theses Collection (Open Access)

Recent years have seen a large increase in the volume of financial news available to investors daily. What has traditionally been restricted to print media has now evolved to include the internet and satellite television as important media sources for financial news. With this overwhelming flow of information available to investors, the impact of financial news on market prices is at best uncertain. In this paper, a computational text-scoring methodology will be employed to uncover behavioral responses by investors to negative news. The empirical methodology employed in this paper will consist of three parts. Firstly, through the General Inquirer (GI) …

Idiosyncratic Risk And Risk Taking Behavior Of Mutual Fund Managers, Gao Wang

Dissertations and Theses Collection (Open Access)

I propose that various measures of mutual funds’ performance are more consistent with their investment capability when mutual funds present low idiosyncratic risks. This paper finds conditional predictor for funds’ returns: alpha predicts returns positively for low idiosyncratic risk funds. It suggests that mutual funds which showed high alpha and low idiosyncratic risk in the past may be capable in investment. Their performance is consistently higher than funds with low idiosyncratic risk and low alpha. On the other hand, the performance of high idiosyncratic risk funds is more likely to reverse in the future: expected returns are low for high …

Dynamic Quay Crane Allocation, Yan Zhang

Dissertations and Theses Collection (Open Access)

We introduce simple rules for quay cranes to handle containers along a berth where vessels arrive continuously in time. We first analyze a model where workload is continuous. Our analysis shows that if the system is configured properly, it will always converge to a state with the maximum possible throughput regardless of external disruptions or changes in workload. Numerical simulations based on a discrete workload model suggest that, by following the same rules, the system can still converge to state with throughput that is very close to its upper bound.

Pricing And Inventory Control In Dual-Channel Network With One Manufacturer And Retailer, Zhicong Pan

Dissertations and Theses Collection (Open Access)

The study on multi-channel problems has been one of the most active research fields in recent years. In this paper, we consider a dual-channel network problem with one manufacture and one retailer. The manufacturer, acting as the Stackelberg leader, sells a single type of product through a traditional channel to the retailer and/or through a direct channel to customers. The retailer, acting as the follower, operates a Newsvendor model, ordering from the manufacturer and selling to the customers. We study the problem with the deterministic demand. We develop an efficient algorithm to find the joint optimal policy for three prices: …

A Flexible Payment Scheme In Hotel Business, Ciwei Dong

Dissertations and Theses Collection (Open Access)

This paper introduces a flexible payment scheme in the hotel business. When a customer makes a reservation for a hotel room, the hotel offers an optional payment scheme (Scheme O). If the customer chooses the Scheme O, he/she makes a non-refundable down payment immediately. Meanwhile, the hotel offers a discount if the customer actually checks in to the hotel. Thus, the payment at check-out time is much lower than the original rental rate. Alternatively, if the customer rejects the Scheme O, the reservation is made under a traditional Scheme (Scheme T), where no down payment is required. However, the customer …

Risk Response Strategies In The Supply Chain: Examining Attributes Of Stakeholders And Risk Attitude, Shu Jian Lim

Dissertations and Theses Collection (Open Access)

Supply chain management is about managing flows of material, information and funds in a complex network of entities of suppliers, manufacturers, distributors and customers. Companies are now connected in this network as an extended enterprise and any company may be involved in more than one such extended enterprises. But, such a network of relationships is very much vulnerable to disruptions of all sorts ranging from internal to inter-firm and to external turbulences. Companies now need to be prepared for risks associated with their participation in the supply chain network. Not many works in the literature have used theories to study …

Pricing And Lead Time Decisions In A Duopoly Common Retailer Channel, Xiuming Niu

Dissertations and Theses Collection (Open Access)

This thesis studies a dual-level decentralized supply chain consisting of two suppliers and two retailers facing a price- and lead-time-sensitive demand. We model the suppliers’ operations as M/M/1 queues and demand as a linear function of the retail prices and promised delivery lead-times offered to the customers. Three different kinds of games are constructed to analyze the pricing and lead-time decisions of the suppliers and retailers. We show the existence of a unique equilibrium in all games and provide the exact formulas to compute the optimal decisions for both the suppliers and retailers. We further present numerical examples to illustrate …
