Doing More With Mobile Networks: More Users, More Uses?, Knowledge@SMU 2010 Singapore Management University

Doing More With Mobile Networks: More Users, More Uses?, Knowledge@Smu

Knowledge@SMU

With so many mobile devices entering the market, from hand phones to laptops and now, iPads and Kindles, it is no wonder that more and more people are jumping on board the mobile bandwagon. However, are today's mobile networks designed to serve and connect a fast expanding number of users? It makes sense that when too many users enter a network, that network will become congested and connectivity will be compromised – or will it? According to SMU information systems assistant professor Kyriakos Mouratidis, "spatial optimisation" of existing connection points within a network may break new grounds in enhancing the ...

An Economist's Take On The Opportunities And Threats That Lie Ahead For Asia, Knowledge@Smu

Knowledge@SMU

Say you have the ability to foresee the ups and downs of the economy; what would you do with that power? Stephen Roach's answer: Become a celebrated economist, columnist and author! His latest book, The Next Asia, is a 2006 to 2009 greatest hits collection of essays on what, he believes, are the region's shortfalls and opportunities. There is plenty to chew upon – from what Roach believes are the factors that led to the recent financial crisis to the various issues that will plague the continent's rapidly developing economies.


Sustainable Supply Chains: Multicriteria Decision-Making And Policy Analysis For The Environment, Trisha D. Woolley 2010 University of Massachusetts Amherst

Sustainable Supply Chains: Multicriteria Decision-Making And Policy Analysis For The Environment, Trisha D. Woolley

Open Access Dissertations

It is believed that the critical next step from examinations of operations and the environment is the study of sustainability and supply chains (Linton, Klassen, and Jayaraman (2007)). Environmental quality and preservation as well as meeting the stress of emission reductions is rapidly becoming an important issue for public policy (Wilkinson, Hill, and Gollan (2001)). However, Lambertini and Mantovani (2007) note the disregard, unrelated to regulatory requirements, of research practitioners to the potential benefits of appropriate competition policy measures and consumer pressures (Srivastara (2007)). In addition, a firm’s success, notably, in terms of financial and/or environmental practices, has ...


Accessing Organizational Resources And Pursuing Value Through International Promotional Alliances, Joe Bryon Cobbs 2010 University of Massachusetts Amherst

Accessing Organizational Resources And Pursuing Value Through International Promotional Alliances, Joe Bryon Cobbs

Open Access Dissertations

Accessing and exploiting organizational resources plays an integral role in not only a firm’s propensity to achieve a competitive advantage, but also its mere survival in a competitive environment (Ulrich & Barney, 1984). One of the most common means of resource acquisition for both large administrative firms and smaller entrepreneurial enterprises is interorganizational alliances (Ireland, Hitt, & Vaidyanath, 2002). Utilizing the resource-based view of the firm within a strategic alliance framework, this dissertation examines a particular type of interorganizational exchange relationship permeating the marketing discipline. The promotional alliance is defined within this research as a strategic alliance based on resource exchange between a promoting enterprise and a firm seeking to fulfill promotion-based objectives through an ongoing collaboration with the enterprise. Each of the two sides of the promotional alliance relationship served as a focus for one of the two studies presented within this work. In the first study, a longitudinal survival model was employed to investigate the dependency of a promotional enterprise on external resource acquisition via alliances with promotion-seeking firms. Also at issue were the heterogeneity of resources accessed and the dynamics of the institutional forces regulating such alliances. Alliances with sponsoring firms offering financial and performance-based resources, as opposed to operational resources, were found to have a significant influence on the survival of sponsored enterprises. However, these dependencies were subject to changes in institutional support and the potential for diminishing returns. The second study approached promotional alliances from the perspective of the firms seeking promotion. Relying on the theory of efficient capital markets (Fama, 1970), an event study analysis was undertaken to determine the impact of internationally prominent promotional alliance announcements on the equity value of the sponsoring firms, which theoretically reflects investors’ expectations of future cash flows. Contrary to prior research, the initiation of these alliances demonstrated a negative impact on shareholder value. Several alliance, firm, and promoting partner characteristics were hypothesized to influence alliance outcomes to varying degrees within the cross-sectional sample of promotion-seeking firms. Surprisingly, only the magnitude of the sponsoring firm’s alliance investment and the nationality congruence within the alliance were influential in predicting investors’ reaction to such alliances. Each study was embedded within the institutional context of Formula One (F1) motor racing and focused on the promotional alliances involving corporate partners (sponsoring firms) and their affiliated racing teams. In this context, the racing teams acted as the promoting enterprises charged with providing the marketing platform to meet their sponsoring firms’ objectives. With annual races on four or more continents; a global television audience rivaled only by the Olympics’ opening ceremony, FIFA World Cup finals, and the NFL’s Super Bowl; direct competition between promoting teams; and sponsoring firms hailing from fifteen different nations and over twenty diverse industry sectors; F1 provided an ideal setting for the evaluation of interorganizational alliances’ impact on the survival of promoting enterprises and a promotion-seeking firm’s value implications. To compliment and strengthen ...


A Tale Of A Town: Artists Crafting "The Creative Class", Arturo Osorio Fernandez 2010 University of Massachusetts Amherst

A Tale Of A Town: Artists Crafting "The Creative Class", Arturo Osorio Fernandez

Open Access Dissertations

This dissertation presents an alternative understanding to current works exploring the creative class. Extant views of the creative class portray it as a concentration of individuals and organizations producing clusters of interconnected cultural activities fostering positive socioeconomic change in the communities where they are located. By contrast, this dissertation articulates the creative class as time evolving geographical organizing of networked creative individuals whose presence over time in a community may or may not foster positive socioeconomic change. The creative class is thus conceptualized as contingent and continuously evolving processes whose emergence at any one point in time may or may ...


Sourcing Reform Competency And Effective Collaboration: A Resource Based View, Sudhi SESHADRI 2010 Singapore Management University

Sourcing Reform Competency And Effective Collaboration: A Resource Based View, Sudhi Seshadri

Research Collection Lee Kong Chian School Of Business

Firms in the Asia Pacific region are rapidly globalizing their sourcing processes and effective collaboration with suppliers across borders is necessary for superior sourcing performance. Recent work in Resource Based View calls for business process level research into the resource-performance link and for survey research into global sourcing. We report on a survey research study with managers in the region, and develop measures that link practices to the goals of De-Constraining, Re-Branding and Re-Optimizing. We develop a model and test hypotheses based on predictions of RBV. We find that a latent sourcing resource Reform Competency is positively associated with these ...

The rapid expansion in assets managed by the Australian managed fund industry has resulted in it becoming a major sector of the financial system, second only to that of the banking industry. With more than A$550 billion invested in the industry investors should be concerned about the lack of reliable information available in regard to equity style management. In particular investors should be concerned about the probable mis-match between stated objectives and the actual objectives pursued by fund managers. In this study, we apply return-based style analysis (Sharpe 1988, 1992) to investigate the style and asset allocation strategies of ...


An Analysis Of Extreme Price Shocks And Illiquidity Among Systematic Trend Followers, Wing Bernard LEE, Shih-Fen CHENG, Annie KOH 2010 Singapore Management University

An Analysis Of Extreme Price Shocks And Illiquidity Among Systematic Trend Followers, Wing Bernard Lee, Shih-Fen Cheng, Annie Koh

Research Collection Lee Kong Chian School Of Business

We construct an agent-based model to study the interplay between extreme price shocks and illiquidity in the presence of systematic traders known as trend followers. The agent-based approach is particularly attractive in modeling commodity markets because the approach allows for the explicit modeling of production, capacities, and storage constraints. Our study begins by using the price stream from a market simulation involving human participants and studies the behavior of various trend-following strategies, assuming initially that their participation will not impact the market. We notice an incremental deterioration in strategy performance as and when strategies deviate further and further from the ...

The Optimal Degree Of Reciprocity In Tariff Reduction, Pao Li CHANG 2010 Singapore Management University

The Optimal Degree Of Reciprocity In Tariff Reduction, Pao Li Chang

Research Collection School Of Economics

This article clari.es the roles played by trade policy, in contrast with iceberg transport cost, in the popular setting of Melitz (2003), and characterizes the optimal reciprocal trade policy in such a setting. I show that import tariffs and iceberg transport cost are not equivalent in the strength of their trade-restricting e¤ects and their welfare implications. With all the con.icting effectsof import tari¤s on welfare considered, the optimal degree of reciprocity in multilateral tari¤ reduction turns out to be free trade.


Audit Market Concentration And Audit Quality, Sanjay KALLAPUR, Srinivasan SANKARAGURUSWAMY, Yoonseok ZANG 2010 Singapore Management University

Audit Market Concentration And Audit Quality, Sanjay Kallapur, Srinivasan Sankaraguruswamy, Yoonseok Zang

Research Collection School Of Accountancy

Policymakers and regulators have been concerned about the impact of audit market concentration resulting from decline in the number of audit firms due to mergers and the demise of Arthur Andersen. In this paper we find a positive association between audit market concentration (Herfindahl index) at the MSA level and audit quality (measured by discretionary accruals and the Dechow-Dichev (2002) measure of accrual quality). We control for fixed year effects, therefore our results are unlikely to be affected by the increase in concentration due to Andersen’s demise contemporaneous with an increase in audit quality because of regulatory measures such ...


The Duration Of Foreclosures In The Subprime Mortgage Market: A Competing Risks Model With Mixing, Anthony Pennington-Cross 2010 Marquette University

The Duration Of Foreclosures In The Subprime Mortgage Market: A Competing Risks Model With Mixing, Anthony Pennington-Cross

Finance Faculty Research and Publications

This paper examines what happens to mortgages in the subprime mortgage market once foreclosure proceeding are initiated. A multinomial logit model that allows for the interdependence of the possible outcomes or risks (cure, partial cure, paid off, and real estate owned) through the correlation of associated unobserved heterogeneities is estimated. The results show that the duration of foreclosures is impacted by many factors including contemporaneous housing market conditions, the prior performance of the loan (prior delinquency), and the state-level legal environment.


Upheaval In The Boardroom: Outside Director Public Resignations, Motivations, And Consequences, Michael Dewally, Sarah Peck 2010 Marquette University

Upheaval In The Boardroom: Outside Director Public Resignations, Motivations, And Consequences, Michael Dewally, Sarah Peck

Finance Faculty Research and Publications

We investigate the motives and circumstances surrounding outside directors' decisions to publicly announce their board resignations. Directors who leave "quietly" are in their mid-sixties and professional directors, i.e., retirees, who are retiring entirely from professional life. Directors who announce their resignation are in their mid-fifties and active professionals. Half the time they say they are leaving because they are "busy." These directors leave from firms with some weakness in their performance, but with no overt manifestations of cronyism such as excessive compensation of either the CEO or directors. The other half of the time directors leave while publicly criticizing ...


What’S In It For Them? Advantages Of Higher Status Partners In Exchange Relationships, Fabrizio CASTELLUCCI, Gokhan ERTUG 2010 Bocconi University

What’S In It For Them? Advantages Of Higher Status Partners In Exchange Relationships, Fabrizio Castellucci, Gokhan Ertug

Research Collection Lee Kong Chian School Of Business

This article explores the motivations that high-status firms have to enter exchange relationships with lower-status partners. We argue that high-status firms can secure greater effort from lower-status partners and that the amount of effort will be proportional to their status advantage over these partners. We further propose that such effort will translate to increased performance by mediating the negative consequences of affiliations with lower-status partners. This increase in performance constitutes the motivation for high-status firms to enter exchange relationships with lower-status partners. Findings using data on Formula One racing support our argument.


Disambiguating The Role Of Ambiguity In Perceptual Assimilation And Contrast Effects, Michelle P. LEE, Kwanho SUK 2010 Singapore Management University

Disambiguating The Role Of Ambiguity In Perceptual Assimilation And Contrast Effects, Michelle P. Lee, Kwanho Suk

Research Collection Lee Kong Chian School Of Business

We examine how perceptions of a product are affected by the presence of extreme exemplars and find that ambiguity of the product is an important moderator. When the target is a novel one, perceptions assimilate to the context, whereas when it is highly familiar, perceptions are immune to the influence of context. This is as predicted by the interpretation-comparison model. Contrary to this model, however, we find that effects on perceptions are not always assimilative in nature. When product ambiguity falls between the extremes of novel and highly familiar, a contrast effect in perception can occur. This is consistent with ...


An Investigation Of Value Updating Bidders In Simultaneous Online Art Auctions, Mayukh DASS, Lynne SEYMOUR, Srinivas K. REDDY 2010 Texas Tech University

An Investigation Of Value Updating Bidders In Simultaneous Online Art Auctions, Mayukh Dass, Lynne Seymour, Srinivas K. Reddy

Research Collection Lee Kong Chian School Of Business

Simultaneous online auctions, in which the auction of all items being sold starts at the same time and ends at the same time, are becoming popular especially in selling items such as collectables and art pieces. In this paper, we analyze the characteristics of bidders (Reactors) in simultaneous auctions who update their pre-auction value of an item in the presence of influencing bidders (Influencers). We represent an auction as a network of bidders where the nodes represent the bidders participating in the auction and the ties between them represent an Influencer?Reactor relationship. We further develop a random effects bilinear ...


Hotel Management Contracts – Past And Present, Jan A. deRoos 2010 Cornell University

Hotel Management Contracts – Past And Present, Jan A. Deroos

Articles and Chapters

Conceived as a relatively simple arrangement that allowed international expansion by hotel chain operators without the risk of real estate ownership, the management contract has become an intricate and nearly essential element of the contemporary hotel industry. While trends in management contracts have shifted with the relative bargaining power of owners and operators, the key to a successful contract is aligning the interests of all parties. Owners seek some reasonable guarantee of cash flow, while operators need assurance that they will be able to benefit from their continued operation of a property. In place of a single document, management contracts ...


How Employment Law Became A Major Issue For Hotel Operators, David Sherwyn 2010 Cornell University

How Employment Law Became A Major Issue For Hotel Operators, David Sherwyn

Articles and Chapters

In the wake of new statutes and case law, issues relating to discrimination have expanded in the past twenty-five years to absorb a substantial amount of management time and attention. The basic law of discrimination is the Civil Rights Act of 1964, which created specific protect classes. That law was revised and expanded in 1991, and other causes of discrimination were added by such laws as the Americans with Disabilities Act and the Age Discrimination in Employment Act. Supreme Court decisions have clarified and expanded certain aspects of the laws, notably the definition of sexual harassment. Perhaps the fastest-growing complaint ...


Pleasurable Surprises: A Cross-Cultural Study Of Consumer Responses To Unexpected Incentives, Ana Valenzuela, Barbara Mellers, Judi Strebel 2010 University of Pennsylvania

Pleasurable Surprises: A Cross-Cultural Study Of Consumer Responses To Unexpected Incentives, Ana Valenzuela, Barbara Mellers, Judi Strebel

Marketing Papers

Consumer reactions to a surprising event are generally stronger than those to an identical but unexpected event. But the experience of surprise differs across cultures. In this article, we examine differences between East Asian and Western emotional reactions to unexpected incentives. When given an unexpected gift, East Asians report less surprise and less pleasure than Westerners. East Asians’ dampened pleasure is explained by their motivation to maintain balance and emotional control, which leads to a reappraisal of perceived likelihood. However, if the unexpected gift is attributed to good luck, which is a desirable form of the unexpected, East Asians experience ...

Wireless Insecurity: Examining User Security Behavior On Public Networks, Tim Chenoweth, Robert Minch, Sharon Tabor

Robert P. Minch

Wireless access points are increasingly serving as entry points to the Internet, increasing connectivity options and security concerns. Particularly significant are public access points, commonly known as hotspots, which are often located in heavily populated areas such as airports, coffee shops, and hotels, appealing to both business and casual users, but offering little or no security.
