A Nonparametric Method For Pricing And Hedging American Options, Guiyun Feng, Guangwu Liu, Lihua Sun Dec 2013

A Nonparametric Method For Pricing And Hedging American Options, Guiyun Feng, Guangwu Liu, Lihua Sun

Research Collection Lee Kong Chian School Of Business

In this paper, we study the problem of estimating the price of an American option and its price sensitivities via Monte Carlo simulation. Compared to estimating the option price which satisfies a backward recursion, estimating the price sensitivities is more challenging. With the readily-computable pathwise derivatives in a simulation run, we derive a backward recursion for the price sensitivities. We then propose nonparametric estimators, the k-nearest neighbor estimators, to estimate conditional expectations involved in the backward recursion, leading to estimates of the option price and its sensitivities in the same simulation run. Numerical experiments indicate that the proposed method works …

Designing Optimal Innovation Portfolio, Arcot Desai Narasimhalu Dec 2013

Designing Optimal Innovation Portfolio, Arcot Desai Narasimhalu

Research Collection School Of Computing and Information Systems

There have been many approaches towards investing in innovation projects. There has been very little discussion about the need to align such investments with the mission, vision, goals, leadership style, value discipline and risk appetite of an organization. This paper reviews existing approaches to innovation related investments and suggests the setting up of a proper innovation portfolio management process along with three dashboards that will help make innovation related investment decisions in an informed manner. The resulting innovation portfolio will be optimal in its alignment with an organizations mission and vision. We expect this method to be used by all …

Social Media For Supply Chain Risk Management, Xiuju Fu, Rick S. M. Goh, J. C. Tong, Loganathan Ponnanbalam, Xiaofeng Yin, Zhaoxia Wang, H. Y. Xu, Sifei Lu Dec 2013

Social Media For Supply Chain Risk Management, Xiuju Fu, Rick S. M. Goh, J. C. Tong, Loganathan Ponnanbalam, Xiaofeng Yin, Zhaoxia Wang, H. Y. Xu, Sifei Lu

Research Collection School Of Computing and Information Systems

With the rapid increase of online social network users worldwide, social media feeds have become a rich and valuable information resource and attract great attention across diversified domains. In social media data, there are abundant contents of two-way and interactive communication about products, demand, customer services and supply. This makes social media a valuable channel for listening to the voices from the market and measuring supply chain risks and new market trends for companies. In this study, we surveyed the potential value of social media in supply chain risk management (SCRM) and examined how they can be applied to SCRM …

Financial Reporting Quality Of Chinese Reverse Merger Firms: The Reverse Merger Effect Or The China Effect?, Kun-Chih Chen, Qiang Cheng, Ying Chou Lin, Yu-Chen Lin, Xing Xiao Dec 2013

Financial Reporting Quality Of Chinese Reverse Merger Firms: The Reverse Merger Effect Or The China Effect?, Kun-Chih Chen, Qiang Cheng, Ying Chou Lin, Yu-Chen Lin, Xing Xiao

Research Collection School Of Accountancy

In this paper, we examine why Chinese reverse merger (RM) firms have lower financial reporting quality. We find that while U.S. RM firms have similar financial reporting quality as matched U.S. IPO firms, Chinese RM firms exhibit lower financial reporting quality than Chinese ADR firms. We further find that Chinese RM firms exhibit lower financial reporting quality than U.S. RM firms. These results indicate that the use of RM process is associated with poor financial reporting quality only in firms from China, where the legal enforcement is weaker than U.S. In addition, we find that compared to Chinese ADR firms, …

A Dynamic Programming Approach To Achieving An Optimal End State Along A Serial Production Line, Shih-Fen Cheng, Blake E. Nicholson, Marina A. Epelman, Daniel J. Reaume, Robert L. Smith Dec 2013

A Dynamic Programming Approach To Achieving An Optimal End State Along A Serial Production Line, Shih-Fen Cheng, Blake E. Nicholson, Marina A. Epelman, Daniel J. Reaume, Robert L. Smith

Research Collection School Of Computing and Information Systems

In modern production systems, it is critical to perform maintenance, calibration, installation, and upgrade tasks during planned downtime. Otherwise, the systems become unreliable and new product introductions are delayed. For reasons of safety, testing, and access, task performance often requires the vicinity of impacted equipment to be left in a specific “end state” when production halts. Therefore, planning the shutdown of a production system to balance production goals against enabling non-production tasks yields a challenging optimization problem. In this paper, we propose a mathematical formulation of this problem and a dynamic programming approach that efficiently finds optimal shutdown policies for …

Decision Trees To Model The Impact Of Disruption And Recovery In Supply Chain Networks, Loganathan Ponnanbalam, L. Wenbin, Xiuju Fu, Xiaofeng Yin, Zhaoxia Wang, Rick S. M. Goh Dec 2013

Decision Trees To Model The Impact Of Disruption And Recovery In Supply Chain Networks, Loganathan Ponnanbalam, L. Wenbin, Xiuju Fu, Xiaofeng Yin, Zhaoxia Wang, Rick S. M. Goh

Research Collection School Of Computing and Information Systems

Increase in the frequency of disruptions in the recent times and their impact have increased the attention in supply chain disruption management research. The objective of this paper is to understand as to how a disruption might affect the supply chain network - depending upon the network structure, the node that is disrupted, the disruption in production capacity of the disrupted node and the period of the disruption - via decision trees. To this end, we first developed a 5-tier agent-based supply chain model and then simulated it for various what-if disruptive scenarios for 3 different network structures (80 trials …

Divided We Stand: Defying Hegemony In Global Public Relations And Practice?, Gregor Halff, Anne Gregory Dec 2013

Divided We Stand: Defying Hegemony In Global Public Relations And Practice?, Gregor Halff, Anne Gregory

Research Collection Lee Kong Chian School Of Business

The last decade has seen the world becoming increasingly complex. One way of dealing with complexity, according to Schwab (2010a, is to look for certainties or solutions that impose order by simplifying. The authors contend that this is a risk in public relations practice and the academy. While recognizing their benefits they warn against attempts to produce global models which also seek to impose hegemony and argue for maintaining a diversity that reflects reality. They take the cases of the UK and Singapore as respective exemplars where hegemony has arguably occurred and where it can still be resisted. They call …

Market Orientation, Embeddedness And The Autonomy And Performance Of Multinational Subsidiaries In An Emerging Economy, Xiaoying Li, Xiaming Liu, Howard Thomas Dec 2013

Market Orientation, Embeddedness And The Autonomy And Performance Of Multinational Subsidiaries In An Emerging Economy, Xiaoying Li, Xiaming Liu, Howard Thomas

Research Collection Lee Kong Chian School Of Business

This paper develops a conceptual framework for market orientation, embeddedness, autonomy and performance of multinational subsidiaries in an emerging economy. We argue that internal and external embeddedness has different performance implications for export- and local market-oriented multinational subsidiaries. Our results, based on a sample of 233 multinational subsidiaries from China, indicate that while external embeddedness has a positive impact on specialized resources of both types of subsidiary, such resources only positively affect the performance of local market-oriented subsidiaries. By contrast, internal embeddedness has a negative impact on specialized resources of both types of subsidiary. Managerial and policy implications are discussed.

The Costs Of Ambient Cultural Disharmony: Indirect Intercultural Conflicts In Social Environment Undermine Creativity, Roy Y. J. Chua Dec 2013

The Costs Of Ambient Cultural Disharmony: Indirect Intercultural Conflicts In Social Environment Undermine Creativity, Roy Y. J. Chua

Research Collection Lee Kong Chian School Of Business

Intercultural tensions and conflicts are inevitable in the global workplace. This paper introduces the concept of ambient cultural disharmony—indirect experience of intercultural tensions and conflicts in individuals' immediate social environment—and demonstrates how it undermines creative thinking in tasks that draw on knowledge from multiple cultures. Three studies (a network survey and two experiments) found that ambient cultural disharmony decreases individuals' effectiveness at connecting ideas from disparate cultures. Beliefs that ideas from different cultures are incompatible mediate the relationship between ambient cultural disharmony and creativity. Alternative mechanisms such as negative affect and cognitive disruption were not viable mediators. Although ambient cultural …

Followership, Leadership And Social Influence, Burak Oc, Michael R. Bashshur Dec 2013

Followership, Leadership And Social Influence, Burak Oc, Michael R. Bashshur

Research Collection Lee Kong Chian School Of Business

Traditional research in leadership has largely relegated followers to the role of passive recipients or, at best, moderators of leader influence and behaviors. However, recent work in the area of followership has begun shifting this focus and emphasizing the possibility that followers actively have an influence over leaders, in particular leader behavior. This paper revisits traditional areas of the leadership literature and builds on the emerging followership literature to reintroduce followers as part of the social context of leaders. In an attempt to build theoretical rationales for how followers influence leader behavior we draw on the social influence (e.g., Social …

Counterparty Responses To Managerial Overconfidence, Paul Hribar, Jaewon Kim, Ryan Wilson, Holly I-Hwa Yang Dec 2013

Counterparty Responses To Managerial Overconfidence, Paul Hribar, Jaewon Kim, Ryan Wilson, Holly I-Hwa Yang

Research Collection School Of Accountancy

Existing research links CEO overconfidence to a number of corporate decisions including overinvestment, external acquisitions, and earnings management. These findings raise the question of whether counterparties distinguish between differences in CEOs, and how they respond to it. We focus on two key counterparties – auditors and credit rating agencies – and examine whether audit fees and credit ratings are affected by CEO overconfidence. We find a positive association between audit fees and CEO overconfidence, suggesting that auditors exert more effort or increase the risk premium associated with auditing firms with more overconfident CEOs. We also find a significant negative association …

Socialization Tactics: Antecedents For Goal Interdependence And Newcomer Adjustment And Retention, Serena Changhong Lu, Dean Tjosvold Dec 2013

Socialization Tactics: Antecedents For Goal Interdependence And Newcomer Adjustment And Retention, Serena Changhong Lu, Dean Tjosvold

Research Collection Lee Kong Chian School Of Business

This study argues that Deutsch's theory of goal interdependence is useful to examine the dynamics of serial and investiture tactics on newcomer adjustment and retention in work team contexts. Structural equation results of interviews of specific incidents collected from one hundred and two newcomers support the hypothesized model that serial and investiture tactics used by teams promote cooperative goal interdependence and weaken competitive goal interdependence and independent goal relationship between newcomers and their teams. Cooperative goals were also found to promote positive attitudes and strong co-worker relationships whereas competitive and independent goals resulted in intentions to quit and low levels …

Management Forecast Credibility And Underreaction To News, Jeffrey Ng, Irem Tuna, Rodrigo Verdi Dec 2013

Management Forecast Credibility And Underreaction To News, Jeffrey Ng, Irem Tuna, Rodrigo Verdi

Research Collection School Of Accountancy

In this paper, we first document evidence of underreaction to management forecast news. We then hypothesize that the credibility of the forecast influences the magnitude of this underreaction. Relying on evidence that more credible forecasts are associated with a larger reaction in the short window around the management forecasts and a smaller post-management forecast drift in returns, we show that the magnitude of the underreaction is smaller for firms that provide more credible forecasts. Our paper contributes to the literature by providing out-of-sample evidence of the drift in returns documented in the post-earnings-announcement drift literature, with the credibility of the …

Price Shocks, News Disclosures, And Asymmetric Drifts, Hai Lu, Kevin Wang, Xiaolu Wang Dec 2013

Price Shocks, News Disclosures, And Asymmetric Drifts, Hai Lu, Kevin Wang, Xiaolu Wang

Research Collection School Of Accountancy

Motivated by investor disagreement and corporate disclosure literatures, we examinehow stock price shocks affect future stock returns. We find that both large short-termprice drops and hikes are followed by negative abnormal returns over the subsequent year,consistent with the conjecture that price shocks are useful indicators of inter-temporalspikes in investor disagreement and investor opinion converges gradually. The asymmetricdrifts, return continuation for negative price shocks versus return reversal for positive ones,are in sharp contrast to the general findings of symmetric drifts in corporate event studies.Moreover, price shocks associated with public news events are followed by significantlyweaker downward drifts, suggesting that news disclosures …

The Evolution Of Enterprise Resource Planning Systems As An It Innovation: A Performative Perspective, Adrian Yeow, Wee Kiat Lim Dec 2013

The Evolution Of Enterprise Resource Planning Systems As An It Innovation: A Performative Perspective, Adrian Yeow, Wee Kiat Lim

CMP Research

How can we improve theorizing on IT innovation? We first draw on theories from IS research and science and technology studies (STS) to explain IT innovation. By showing how limited these research streams can be because they have not accounted for the act of theorizing itself, we next turn to the theory of performativity as a candidate theory to extend our understanding of IT innovation. We use an exemplar of IT innovation, enterprise resource planning (ERP) systems, to develop a performative perspective of the IT innovation process. Based on our preliminary data collection and analysis, we surfaced the role of …

The Influence Of Online Word-Of-Mouth On Long Tail Formation, Bin Gu, Qian Tang, Andrew B. Whinston Dec 2013

The Influence Of Online Word-Of-Mouth On Long Tail Formation, Bin Gu, Qian Tang, Andrew B. Whinston

Research Collection School Of Computing and Information Systems

The long tail phenomenon has been attributed to both supply side and demand side economies. While the cause on the supply side is well-known, research on the demand side has largely focused on the awareness effect of online information that helps consumers discover new and often niche products. This study expands the demand side factors by showing that online information also influences the long tail phenomenon through the informative effect, which affects consumers' evaluation of product quality. We examine the informative effect in the context of online WOM. Two sets of theories suggest opposite directions for the implication of the …

Disproportional Ownership Structure And Ipo Long-Run Performance Of Entrepreneurial Firm In China, Jerry X. Cao, Gary Gang Tian, Vincent Tang, Xiaoming Wang Dec 2013

Disproportional Ownership Structure And Ipo Long-Run Performance Of Entrepreneurial Firm In China, Jerry X. Cao, Gary Gang Tian, Vincent Tang, Xiaoming Wang

Research Collection Lee Kong Chian School Of Business

This paper examines the relationship between ownership structures and IPO long-run performance in China. Although entrepreneurial firms underperform the market in general after IPO but the poor performance is mainly caused by the IPOs with ownership control wedge. Entrepreneurial firms with one share one vote structure outperform those with ownership control wedge by 30% for 3 years post-IPO in either buy-and-hold or cumulative monthly returns. Entrepreneurial firms with excess ownership control wedge have higher frequency of undertaking value-destroying related party transactions. These findings suggest that entrepreneurial firms need to improve corporate governance such as disproportional ownership structure to better safeguard …

Institutional Presence, Johan Sulaeman, Chi Shen Wei Dec 2013

Institutional Presence, Johan Sulaeman, Chi Shen Wei

Research Collection Lee Kong Chian School Of Business

We propose an Institutional Presence (IP) measure to capture the latent role of non-owner institutional investors who nevertheless may be observing a firm. We employ this measure to examine whether the ‘presence’ of institutional investors reduces information asymmetry in the market. Firms in areas with high institutional presence experience higher liquidity, faster information incorporation, lower costs of equity capital, and less financing frictions relative to firms in low IP areas. The results hold after controlling for firm and geographical characteristics including institutional ownership and urban locality. Our findings indicate that being in the presence of institutional investors brings tangible benefits.

What Are Analysts Really Good At?, Ohad Kadan, Leonardo Madureira, Rong Wang, Tzachi Zach

Research Collection Lee Kong Chian School Of Business

Sell-side analysts employ different benchmarks when defining their stock recommendations. For example, a ‘buy’ for some brokers means the stock is expected to outperform its peers in the same sector (“industry benchmarkers”), while for other brokers it means the stock is expected to outperform the market (“market benchmarkers”), or just some absolute return (“total benchmarkers”). We use these benchmarks to analyze the role of stock picking, industry picking and market timing in contributing to the performance of stock recommendations. We are able to do so given that different benchmarks suggest the use of different sets of abilities. Analysis of the …

Economic Effects Of Sox Section 404 Compliance: A Corporate Insider Perspective, Cindy Alexander, Scott Bauguess, Gennaro Bernile, Alex Lee, Jennifer Marietta-Westberg Dec 2013

Economic Effects Of Sox Section 404 Compliance: A Corporate Insider Perspective, Cindy Alexander, Scott Bauguess, Gennaro Bernile, Alex Lee, Jennifer Marietta-Westberg

Research Collection Lee Kong Chian School Of Business

We use survey responses from 2,901 corporate insiders to assess the costs and benefits of compliance with Section 404 of the Sarbanes-Oxley Act. The majority of respondents recognize compliance benefits, but they do not perceive these benefits to outweigh the costs, on average. This is particularly true among smaller companies where the start-up costs are proportionately larger. However, the perceived efficiency of compliance increases with auditor attestations, years of compliance experience, and after the remediation of a material weakness. Notably, the perceived effects of compliance depend largely on firm complexity, but are mostly unrelated to firm governance structure.

Social Media Hype In Times Of Crises: Nature, Characteristics And Impact On Organizations, Augustine Pang

Research Collection Lee Kong Chian School Of Business

This article extends Vasterman’s (2005) concept of media hype by analyzing how it applies in the social media context. It then develops the concept of social media hype, its nature, characteristics through examination of five cases that attracted much social media attention. Social media hype can be defined as a netizen-generated hype that causes huge interest that is triggered by a key event and sustained by a self-reinforcing quality in its ability for users to engage in conversation. It involves a trigger event, followed by interest waves, and sustaining of the interests on different social media platforms. In response, organizations …

In this article we reflect on our time as editors of JMS during the period 2003-09. First we describe the context as we saw it on assuming editorship of the Journal and the actions that we took to improve the quality of scholarship published in the journal in order to set JMS on the trajectory to become a world-leading Journal. We articulate our view of what quality means in this context and observe that we eschewed the USA-Europe divide. Rather, to be publishable, all papers had to meet the highest standards relative to their epistemological assumptions. Finally, we address two …

Effects Of Messages Emphasizing Environmental Determinants Of Obesity On Intentions To Engage In Diet And Exercise Behaviors, Jeff Niederdeppe, Sungjong Roh, Michael A. Shapiro, Hye Kyung Kim Dec 2013

Effects Of Messages Emphasizing Environmental Determinants Of Obesity On Intentions To Engage In Diet And Exercise Behaviors, Jeff Niederdeppe, Sungjong Roh, Michael A. Shapiro, Hye Kyung Kim

Research Collection Lee Kong Chian School Of Business

Reducing rates of obesity will require interventions that influence both individual decisions and environmental factors through changes in public policy. Previous work indicates that messages emphasizing environmental determinants increases support for public policies, but some suspect this strategy may undermine motivation to engage in diet and exercise. Emphasizing factors outside of personal control appears to enhance rather than undermine motivations to engage in healthy diet and exercise behavior.

Research Collection Lee Kong Chian School Of Business

This article critically compares China's rare earth policy with perspectives upheld in the rest of the world (ROW). We introduce rare earth elements and their importance for energy and present how China and the ROW are framing the policy debate. We find strongly dissonant views with regards to motives for foreign direct investment, China's two-tiered pricing structure and its questionable innovation potential. Using the metaphor of "China Inc.", we compare the Chinese government to a socially responsible corporation that aims to balance the needs of its internal stakeholders with the demands from a resource-dependent world. We find that China's internal …
