Production Cost Heterogeneity In A Circular-City Model, Mei Lin, Ruhai Wu Jul 2015

Production Cost Heterogeneity In A Circular-City Model, Mei Lin, Ruhai Wu

Research Collection School Of Computing and Information Systems

We derive the closed-form solution characterizing the equilibrium in a circular-city model with competing firms of heterogeneous production costs. Tractability issues in this setting are well known and have not been resolved in prior work. In this paper, the equilibrium solution illustrates effects of production costs on firms’ strategic decisions, their aggregate profit, and consumer surplus.

Opaque Financial Reporting Due To Unemployment Concerns, Jeffrey Ng, Tharindra Ranasinghe, Guifeng Shi, Holly I. Yang Jul 2015

Opaque Financial Reporting Due To Unemployment Concerns, Jeffrey Ng, Tharindra Ranasinghe, Guifeng Shi, Holly I. Yang

Research Collection School Of Accountancy

This paper examines the link between rank-and-file employees’ unemployment concerns and financial reporting opacity. Following Agrawal and Matsa (JFE, 2013), we use exogenous variations in state unemployment insurance benefits to capture changes to unemployment concerns. We find that when unemployment concerns are lower, there is less opaque financial reporting. This relation is stronger when workers face higher unemployment risk, labor union participation is high, and executives have higher equity incentives. Using Tobin’s Q to capture firm value, we also find that the economic rationale to engage in opaque financial reporting reduces when unemployment benefits are high. Our findings suggest that …

Fair Value Hierarchy Measures: Post-Implementation Evidence On Ifrs 7, Pearl Tan Jul 2015

Fair Value Hierarchy Measures: Post-Implementation Evidence On Ifrs 7, Pearl Tan

Research Collection School Of Accountancy

Using a balance sheet valuation model, this study examines if information on the fair value hierarchy of on-balance sheet financial assets and financial liabilities are incorporated in the market’s valuation of companies’ equities in Singapore. The results of the study show significant associations between as-reported Level 1 and Level 2 fair value measures of financial assets and market values. However, the results are not significant for Level 3 fair value measures of financial assets and each of the three levels of fair value measures of financial liabilities. The results also show that returns are more positively associated with as-reported gains …

Socially Desirable Responding: Enhancement And Denial In 20 Countries, Jia He, F.J. Van De Vijver, A.D. Espinosa, A. Abubakar, R. Dimitrova, B.G. Adams, Jochen Reb, Samantha Sim Jul 2015

Socially Desirable Responding: Enhancement And Denial In 20 Countries, Jia He, F.J. Van De Vijver, A.D. Espinosa, A. Abubakar, R. Dimitrova, B.G. Adams, Jochen Reb, Samantha Sim

Research Collection Lee Kong Chian School Of Business

This article investigated the dimensionality, measurement invariance, and cross-cultural variations of social desirability. A total of 3,471 university students from 20 countries completed an adapted version of the Marlowe–Crowne scale. A two-dimensional structure was revealed in the pooled sample, distinguishing enhancement (endorsement of positive self-description) and denial (rejection of negative self-description). The factor structure was supported in most countries; medium-sized item bias was found in two denial items. In a multilevel analysis, we found that (a) there was more cross-cultural variation in denial than enhancement; (b) females tended to score higher on enhancement whereas males tended to score higher on …

Investigating The Uniqueness And Usefulness Of Proactive Personality In Organizational Research: A Meta-Analytic Review, Matthias Spitzmuller, Hock-Peng Sin, Michael Howe, Shereen Fatimah Jul 2015

Investigating The Uniqueness And Usefulness Of Proactive Personality In Organizational Research: A Meta-Analytic Review, Matthias Spitzmuller, Hock-Peng Sin, Michael Howe, Shereen Fatimah

Research Collection Lee Kong Chian School Of Business

Using meta-analysis (283 effect sizes from 122 studies), we extend prior qualitative and quantitativereviews of research on proactive personality in a number of meaningful ways. First, we examine thediscriminant and incremental validity of proactive personality using meta-analytic regression analyses.Our results reveal that more than 50% of variance in proactive personality is unrelated to the BigFive personality traits collectively. Also, proactive personality accounts for unique variance in overalljob performance, task performance, and organizational citizenship behaviors, even after controllingfor the Big Five personality traits and general mental ability (for overall job performance and taskperformance). Moreover, we find no subgroup differences in proactive …

Home Away From Home: Geography Of Information And Local Investors, Gennaro Bernile, Alok Kumar, Johan Sulaeman Jul 2015

Home Away From Home: Geography Of Information And Local Investors, Gennaro Bernile, Alok Kumar, Johan Sulaeman

Research Collection Lee Kong Chian School Of Business

We develop a 10K-based measure of spatial variation in the availability of value-relevant information that reflects the multi-dimensional nature of firm location. Spatially distributed information generates location-based information asymmetries that affect institutional portfolio decisions and performance. Institutions overweigh firms with greater local economic exposure and earn superior returns on corresponding trades, even for firms not headquartered locally. These patterns are stronger among harder-to-value stocks. Consistent with local informational advantage, local investor performance increases with the local exposure of individual stock holdings and her portfolio as a whole, and more so when her portfolio is more heavily tilted toward local stocks.

Customer's Short Positions And Supplier's Investment Decisions, Xia Chen, Guojin Gong, Shuqing Luo Jul 2015

Customer's Short Positions And Supplier's Investment Decisions, Xia Chen, Guojin Gong, Shuqing Luo

Research Collection School Of Accountancy

Short interest contains valuable information about a firm’s business fundamentals. We investigate whether such information affects business partners’ real investment decisions in the supply-chain setting. We predict and find that a supplier’s future investments (including inventory, R&D, and tangible asset investments) decrease with its customer’s current short interest. This negative relation is stronger when the supplier faces greater difficulty in assessing its customer’s business fundamentals and when short interest is more likely to indicate longlasting deterioration in the customer’s fundamentals. Additional analysis does not support the alternative explanation that the supplier adjusts investments in response to unfavorable information obtained via …

Development And Test Of An Integrative Model Of Job Search Behaviour, Greet Van Hoye, Alan M. Saks, Filip Lievens, Bert Weijters Jul 2015

Development And Test Of An Integrative Model Of Job Search Behaviour, Greet Van Hoye, Alan M. Saks, Filip Lievens, Bert Weijters

Research Collection Lee Kong Chian School Of Business

Research on job search and the theory of planned behaviour (TPB) has identified job search attitude, subjective norm, and job search self-efficacy as the most proximal determinants of job seekers' search intentions and subsequently job search behaviours. However, we do not yet know how more distal individual differences (e.g., personality) and situational factors (e.g., social context) might help to predict these key TPB determinants of job search behaviour. In an integrative model of job search behaviour, we propose specific relationships between these distal variables and the TPB determinants, which in turn are expected to mediate the effects of individual differences …

Least Squares Approximation To Stochastic Optimization Problems, Zhichao Zheng, Karthik Natarajan, Chung-Piaw Teo Jul 2015

Least Squares Approximation To Stochastic Optimization Problems, Zhichao Zheng, Karthik Natarajan, Chung-Piaw Teo

Research Collection Lee Kong Chian School Of Business

This paper is motivated by the following question: How to construct good approximation for the distribution of the solution value to linear optimization problem when the objective function is random? More generally, we consider any mixed zero-one linear optimization problem, and develop an approach to approximate the distribution of its optimal value when the random objective coefficients follow a multivariate normal distribution. Linking our model to the classical Stein’s Identity, we show that the least squares normal approximation of the random optimal value can be computed by solving the persistency problem, first introduced by Bertsimas et al. (2006). We further …

When Voice Matters: A Multilevel Review Of The Impact Of Voice In Organizations, Michael R. Bashshur, Burak Oc Jul 2015

When Voice Matters: A Multilevel Review Of The Impact Of Voice In Organizations, Michael R. Bashshur, Burak Oc

Research Collection Lee Kong Chian School Of Business

The conventional wisdom is that voice leads to desirable outcomes for organizations. However, this is most certainly an oversimplification. Of the over 1,000 studies examining the impact of voice in organizations, the implications of voice vary by the level of the organization (individual, group, organization) as well as the outcome of interest (e.g., group harmony vs. job satisfaction). In this article, we draw from the diverse literatures examining the impact of voice to integrate the theoretical frameworks and empirical results for voice outcomes across organizational levels. To do so, we start with a discussion of the definition and development of …

Improving Decision Making Through Mindfulness, Natalie Karelaia, Jochen Reb Jul 2015

Improving Decision Making Through Mindfulness, Natalie Karelaia, Jochen Reb

Research Collection Lee Kong Chian School Of Business

With perhaps a few exceptions per day, we are seldom fully aware of our thoughts, actions, emotions, and what is happening around us. Even when it comes to making decisions, an activity that is often quite conscious, deliberate, and intentional, people are typically not as aware as they could be. We argue that as a result, decision quality may suffer. Consequently, mindfulness, most often defined as the state of being openly attentive to and aware of what is taking place in the present, both internally and externally (e.g., Brown and Ryan 2003; Kabat-Zinn 1982; 1990), can help people make better …

Why Do U.S. Firms Invest Less Over Time?, Fangjian Fu, Sheng Huang, Rong Wang Jul 2015

Why Do U.S. Firms Invest Less Over Time?, Fangjian Fu, Sheng Huang, Rong Wang

Research Collection Lee Kong Chian School Of Business

The ratio of capital expenditure to total assets of U.S. firms decreases by more than half from 1980 to 2012. The decline in capital investment is pervasive; it has occurred for firms in most industries and is robust to firms of different sizes, investment opportunities, profitability, accesses to external financing, and expenses on R&D or acquisitions. Existing theories of corporate investment fall short in explaining the decline trend. The decline is also not explained by time variation in firm characteristics, industry composition, and public listing cohorts, or by corporate lifecycle. Our further evidence suggests that it is related to the …

Density Forecast Evaluation For Dependent Financial Data: Theory And Applications, Aurobindo Ghosh, Anil K. Bera Jul 2015

Density Forecast Evaluation For Dependent Financial Data: Theory And Applications, Aurobindo Ghosh, Anil K. Bera

Research Collection Lee Kong Chian School Of Business

In this paper, we propose a formal test for density forecast evaluation in presence of dependent data. Apart from accepting or rejecting the tested model, our smooth test identifies the possible sources (such as the location, scale and shape of the distribution) of rejection, thereby helping in revising the initial model. We also propose how to augment the smooth test to investigate explicit forms of dependence in the data within the same test framework. An extensive application to S&P 500 returns indicate capturing time-varying volatility and non-gaussianity significantly improve the performance of the model. Although we are dealing with index …

Beyond The Western Masses: Demography And Pakistani Media Credibility Perceptions., Kyujin Shim, Guy J. Golan, Anita G. Day, Sung-Un Yang

Research Collection Lee Kong Chian School Of Business

Based on a random survey sample, the current study examined audience assessments of different media platforms in Pakistan. This study found that in the complex Pakistani media landscape, ethnicity is a key indicator in predicting media credibility. Our study’s results indicate that minority ethnic groups tend to find domestic television to be less credible, and international television or traditional media to be more credible, than do members of the majority Punjabi group. Media reliance was found to be a significant indicator of media credibility assessment — particularly regarding media such as international television and the Internet — as media reliance …

Conclusion, Seshan Ramaswami

Research Collection Lee Kong Chian School Of Business

This book has taken us through the fascinating history of the Indian performing arts in Singapore. The development and spectacular growth of the Indian arts in Singapore have mirrored the economic developments in Singapore. From very slow beginnings of the hardworking pioneering artistes, some institutions have grown dramatically and have become landmark cultural institutions, well known to Singaporeans and arts connoisseurs in India, especially the cognoscenti in the cultural capital of Chennai in the South. In the early days prior to independence, both local and new Indian immigrants were starved for opportunities to learn Indian classical music and dance, and …

The Interplay Of Elicitation And Evaluation Of Trait-Expressive Behavior: Evidence In Assessment Center Exercises, Filip Lievens, Eveline Schollaert, Gert Keen Jul 2015

The Interplay Of Elicitation And Evaluation Of Trait-Expressive Behavior: Evidence In Assessment Center Exercises, Filip Lievens, Eveline Schollaert, Gert Keen

Research Collection Lee Kong Chian School Of Business

In assessment centers (ACs), research on eliciting candidate behavior and evaluating candidate behavior have largely followed independent paths. This study integrates trait activation and trait rating models to posit hypotheses about the effects of behavior elicitation via situational cues on key assessor observation and rating variables. To test the hypotheses, a series of experimental and field studies are conducted. Only when trait-expressive behavior activation and evaluation models work in conjunction, increases in observability are coupled with increases in the interrater reliability, convergent validity, discriminant validity, and accuracy of AC ratings. Implications of these findings for AC theory and practice are …

The Persistence Of Long-Run Abnormal Returns Following Stock Repurchases And Offerings, Fangjian Fu, Sheng Huang Jul 2015

The Persistence Of Long-Run Abnormal Returns Following Stock Repurchases And Offerings, Fangjian Fu, Sheng Huang

Research Collection Lee Kong Chian School Of Business

The long-run abnormal returns following both stock repurchases and seasoned equity offerings disappear for the events in 2003–2012. The disappearance is associated with the changing market environment: increased institutional investment, decreased trading costs, improved liquidity, and enhanced regulations on corporate governance and information disclosure. In response to the more efficient pricing of stocks, firms become less opportunistic in stock repurchases and offerings. Recent events of stock repurchases and offerings are motivated more by business-operating reasons than to exploit mispricing. Both external market factors and internal firm factors contribute to the disappearance of the postevent abnormal returns. Our findings on the …

Leading With Mindfulness: Exploring The Relation Of Mindfulness With Leadership Behaviors, Styles, And Development, Jochen Reb, Samantha Su-Hsien Sim, Kraivin Chintakananda, Devasheesh P. Bhave Jul 2015

Leading With Mindfulness: Exploring The Relation Of Mindfulness With Leadership Behaviors, Styles, And Development, Jochen Reb, Samantha Su-Hsien Sim, Kraivin Chintakananda, Devasheesh P. Bhave

Research Collection Lee Kong Chian School Of Business

This chapter examines the complexities of mindfulness in leadership, exploring potential advantages and disadvantages of mindfulness for leaders. Such an inquiry is important for theoretical development but also has practical implications when considering the design of mindfulness training for leadership and other areas such as employee wellbeing. In the present discussion, we clarify the discussion on mindfulness by distinguishing between the dimensions of mindfulness -- that is present-moment attention, intentionality, attitude of self-compassion, witnessing awareness and clarity -- and suggest ways these dimensions affect leadership behaviors. We also distinguish between mindfulness as a construct and as a practice, to elucidate …

Communicating About Marine Disease: The Effects Of Message Frames On Policy Support, Katherine A. Mccomas, Jonathon P. Schuldt, Colleen A. Burge, Sungjong Roh

Research Collection Lee Kong Chian School Of Business

Oceans are suffering from the dual climatic pressures of warming temperatures and acidification, increasing the presence of disease risks that affect marine organisms and public health. Through a randomized field-based experiment, this study examines the effects of communicating about risks to marine organisms and public health on people’s support for policies aimed at mitigating those risks as a function of different message frames. To maximize the salience of these issues, participants were recruited from ferry passengers (N1⁄4543) in the San Juan Islands of Washington State in the summer of 2013 and randomized to read one of four fictitious news articles …

Perceptions Of Social Norms Surrounding Digital Piracy: The Effect Of Social Projection And Communication Exposure On Injunctive And Descriptive Norms, Hichang Cho, Siyoung Chung, Anna Filippova

Research Collection Lee Kong Chian School Of Business

Using a national sample of 620 Internet users in the US, this study examined the extent to which social projection, communication exposure, and an interaction between the two, influenced individuals’ perceptions about two subordinate types of social norms surrounding digital piracy: injunctive norms and descriptive norms. In line with the social projection model, individuals made social estimates about others’ piracy attitudes and behaviors anchoring on their own personal attitudes and behavior. However, frequent communication exposure reduced the degree to which they relied on this egocentric thought process. In addition, the two-way interaction was contingent on another condition (perceiver’s own piracy …

Will High-Frequency Trading Practices Transform The Financial Markets In The Asia Pacific Region?, Robert John Kauffman, Yuzhou Hu, Dan Ma Jun 2015

Will High-Frequency Trading Practices Transform The Financial Markets In The Asia Pacific Region?, Robert John Kauffman, Yuzhou Hu, Dan Ma

Research Collection School Of Computing and Information Systems

High-frequency trading (HFT) practices in the global financial markets involve the use of information and communication technologies (ICT), especially the capabilities of high-speed networks, rapid computation, and algorithmic detection of changing information and prices that create opportunities for computers to effect low-latency trades that can be accomplished in milliseconds. HFT practices exist because a variety of new technologies have made them possible, and because financial market infrastructure capabilities have also been changing so rapidly. The U.S. markets, such as the National Association for Securities Dealers Automated Quote (NASDAQ) market and the New York Stock Exchange (NYSE), have maintained relevance and …

Showrooming Vs. Competing: How Does Brand Selection Matter?, Qian Tang, Mei Lin Jun 2015

Showrooming Vs. Competing: How Does Brand Selection Matter?, Qian Tang, Mei Lin

Research Collection School Of Computing and Information Systems

In this study, we empirically examine the effect of local shoe store openings on the sales of a competing, major online shoe retailer. Both showrooming and competing effects can play a role: Under the showrooming effect, the local store opening can lead to more online sales for the online retailer, whereas the competing effect created by the local store opening can substitute away the demand for the online retailer. We examine when one effect dominates the other by classifying local stores into single- and mixed-brand stores. We find that the showrooming effect is dominant for a single-brand store opening, and …

Author Topic Model-Based Collaborative Filtering For Personalized Poi Recommendations, Shuhui Jiang, Xueming Qian, Jialie Shen, Yun Fu, Tao Mei Jun 2015

Author Topic Model-Based Collaborative Filtering For Personalized Poi Recommendations, Shuhui Jiang, Xueming Qian, Jialie Shen, Yun Fu, Tao Mei

Research Collection School Of Computing and Information Systems

From social media has emerged continuous needs for automatic travel recommendations. Collaborative filtering (CF) is the most well-known approach. However, existing approaches generally suffer from various weaknesses. For example, sparsity can significantly degrade the performance of traditional CF. If a user only visits very few locations, accurate similar user identification becomes very challenging due to lack of sufficient information for effective inference. Moreover, existing recommendation approaches often ignore rich user information like textual descriptions of photos which can reflect users' travel preferences. The topic model (TM) method is an effective way to solve the "sparsity problem," but is still far …
