Social Space

Social innovation labs are emergent spaces for naming social challenges, testing hypotheses, developing and spreading interventions. Despite the common denominator of experimentation, they vary in methodology. Dr Sarah Schulman makes explicit her observation of the hunches and assumptions embedded in the current social change methodologies.

Fair Cost Sharing Auction Mechanisms In Last Mile Ridesharing, Duc Thien Nguyen Jan 2013

Fair Cost Sharing Auction Mechanisms In Last Mile Ridesharing, Duc Thien Nguyen

Dissertations and Theses Collection (Open Access)

With rapid growth of transportation demands in urban cities, one major challenge is to provide efficient and effective door-to-door service to passengers using the public transportation system. This is commonly known as the Last Mile problem. In this thesis, we consider a dynamic and demand responsive mechanism for Ridesharing on a non-dedicated commercial fleet (such as taxis). This problem is addressed as two sub-problems, the first of which is a special type of vehicle routing problems (VRP). The second sub-problem, which is more challenging, is to allocate the cost (i.e. total fare) fairly among passengers. We propose auction mechanisms where …

Four-Cornered Fight A Blessing In Disguise For Wp, Tan K. B. Eugene Jan 2013

Four-Cornered Fight A Blessing In Disguise For Wp, Tan K. B. Eugene

Research Collection Yong Pung How School Of Law

SMU Assistant Professor of Law and NMP Eugene Tan said that much is at stake for the four political parties contesting the Punggol East by-election. Regardless of how the parties seek to characterise the by-election, it will be fought on both local and national issues. Although it is a four-cornered contest, the race will effectively be a two-horse race between the Workers' Party (WP) and the incumbent People's Action Party (PAP). The by-election is also a way station for PAP and WP as they move towards the next General Election, which promises to be the real watershed election. Assistant Prof …

Three Essays On Mutual Fund Ratings, Wee Seng Ng Jan 2013

Three Essays On Mutual Fund Ratings, Wee Seng Ng

Dissertations and Theses Collection (Open Access)

The incessant growth of the mutual fund industry has made the task of selecting mutual funds an increasingly challenging one. Unsophisticated investors turn to low-cost and readily available ratings to guide their investment decisions. Unsurprisingly, mutual fund ratings are hugely popular and influential. Anecdotal evidence and academic findings both suggest that investors gravitate towards top-rated funds. Rating is a double-edged sword. Although the use of rating simplifies the otherwise onerous job of evaluating mutual fund performance, it can lead to adverse consequences. Investors who invest only in top-rated funds are inadvertently assuming that good ratings indicate good future performance. However, …

Three Essays On Large Panel Data Models With Cross-Sectional Dependence, Yonghui Zhang Jan 2013

Three Essays On Large Panel Data Models With Cross-Sectional Dependence, Yonghui Zhang

Dissertations and Theses Collection (Open Access)

My dissertation consists of three essays which contribute new theoretical results to large panel data models with cross-sectional dependence. These essays try to answer or partially answer some prominent questions such as how to detect the presence of cross-sectional dependence and how to capture the latent structure of cross-sectional dependence and estimate parameters efficiently by removing its effects. Chapter 2 introduces a nonparametric test for cross-sectional contemporaneous dependence in large dimensional panel data models based on the squared distance between the pair-wise joint density and the product of the marginals. The test can be applied to either raw observable data …

Sanctions: Where Law And Justice Collide: Kraze Entertainment (S) Pte Ltd V Marina Bay Sands Pte Ltd [2013] Sghc 39, Denise Huiwen Wong

Research Collection Yong Pung How School Of Law

This is a cautionary tale for litigation practitioners and their claimant clients. The decision emanates from the High Court of Singapore, but is equally applicable to any jurisdiction in which security for costs can be sought against the claimant in an action. In Singapore, the Rules of Court set out the procedural rules governing all civil proceedings in the High Court and Subordinate Courts. Unlike the Civil Procedure Rules (CPR), the Singapore Rules of Court do not expressly articulate an overriding objective of timely and proportionate justice. However, the courts have consistently prioritised robust case management and “an uncompromising but …

Corporate Social Responsibility As Corporate Soft Law: Mainstreaming Ethical And Responsible Conduct In Corporate Governance, Eugene K. B. Tan Jan 2013

Corporate Social Responsibility As Corporate Soft Law: Mainstreaming Ethical And Responsible Conduct In Corporate Governance, Eugene K. B. Tan

Research Collection Yong Pung How School Of Law

This article explores corporate social responsibility ("CSR') as a viable mode of regulation and governance in the corporate arena. A starting premise is that good corporate governance must move resolutely beyond a compliance mindset to one which recognises that effective corporate governance must have an ethical backbone in which the dimensions of responsibility, transparency, and accountability are evident, recognised and supported. Regulatory endeavours and corporate governance reforms in the past decade have increasingly intersected with mainstream CSR motivations. CSR is increasingly inducted and mainstreamed into corporate governance thinking, characterised by the dual perspective ofrisk management and values-driven/principled governance and operations. …

Subjective Well-Being, William Tov, Ed Diener Jan 2013

Subjective Well-Being, William Tov, Ed Diener

Research Collection School of Social Sciences

The cross-cultural importance of happiness and contentment can be inferred from their emergence in philosophical discussions across many cultural traditions. We begin by focusing on similarities, noting what has been found to correlate with the components of SWB across most cultures. Subjective well being (SWB) involves the various ways that people evaluate and experience their lives. In many ways, the term is synonymous with the everyday notion of happiness – positive feelings are an important aspect of well being. Cross-cultural similarities are important because they highlight our common humanity and hint at which factors may be fundamental to wellbeing. Next, …

Measuring Differentials In Communication Research: Issues With Multicollinearity In Three Methods, Sonny Rosenthal Jan 2013

Measuring Differentials In Communication Research: Issues With Multicollinearity In Three Methods, Sonny Rosenthal

Research Collection College of Integrative Studies

Models of communication processes sometimes require the computation of the difference between two variables. For example, information insufficiency is the difference between what people know and what they think they need to know about an issue, and it can motivate information seeking and processing. Common methods that compute this differential may bias model estimates as a function of the correlation between the differentiated variables and other variables in the model. This article describes Citation the general form of Cohen and Cohen's (1983) analysis of partial variance for computing differentials and analyzes simulated data to contrast that method with two alternative …

Negotiating Successfully In Asia, Michael Benoliel Jan 2013

Negotiating Successfully In Asia, Michael Benoliel

Research Collection Lee Kong Chian School Of Business

Cross-cultural negotiations are complex, challenging, and difficult to navigate because much of the Asian culture is unstated, implicit, and internalized in subtle behavioral patterns. It is like an iceberg; more is invisible and less is visible. To understand how the Asian negotiation values and practices are different from those in the West, I describe briefly the Asian cultural roots, highlight the major dimensions that differentiate cultures, explore the factors that influence the Asian negotiation processes and outcomes, and provide a list of practical suggestions for negotiating successful deals with Asian negotiators.

How Does Culture Influence Corporate Risk-Taking?, Kai Li, Dale Griffin, Heng Yue, Longkai Zhao Jan 2013

How Does Culture Influence Corporate Risk-Taking?, Kai Li, Dale Griffin, Heng Yue, Longkai Zhao

Research Collection School Of Accountancy

We investigate the role of national culture in corporate risk-taking. We postulate that culture influencescorporate risk-taking both through its effect on managerial decision-making and through its effect on acountry’s formal institutions. Further, we postulate that the influence of culture is conditioned on theextent of managerial discretion as measured by earnings discretion and firm size. Using firm-level datafrom 35 countries and employing a hierarchical linear modeling approach to isolate the effects of firmleveland country-level variables, we show that individualism has a positive and significant association,whereas uncertainty avoidance and harmony have negative and significant associations, with corporaterisk-taking. Greater earnings discretion strengthens and …

Review On The State Of Sustainability Reporting In Singapore, Soo Chiat Hwang, Teng Aun Khoo, Dan Chi Wong Jan 2013

Review On The State Of Sustainability Reporting In Singapore, Soo Chiat Hwang, Teng Aun Khoo, Dan Chi Wong

Research Collection School Of Accountancy

The trend of sustainability reports has increased inexorably as the clamor by various stakeholders including NGOs have been growing louder and louder. Some countries have even made sustainability reporting mandatory. In Singapore only a small percentage of listed companies are voluntary providing sustainability reporting but this number is set to increase in line with the world trend. As sustainability reporting in Singapore will continue to grow this study attempts to address the perceptions of the importance and usefulness of sustainability reporting, the reporting framework and the training needs of both users and preparers to provide such reports.

A Presence Of The Past: The Legal Protection Of Singapore’S Archaeological Heritage, Jack Tsen-Ta Lee Jan 2013

A Presence Of The Past: The Legal Protection Of Singapore’S Archaeological Heritage, Jack Tsen-Ta Lee

Research Collection Yong Pung How School Of Law

Singapore is not well known for its archaeological heritage. In fact, chance finds in the early 20th century and systematic archaeological excavations since the 1980s conducted at sites around the Singapore River have unearthed artefacts shedding light on the island’s early history. In addition, the value of archaeology for a deeper knowledge of Singapore’s British colonial past is increasingly being recognized. Nonetheless, Singapore law provides only a rudimentary framework to facilitate archaeological investigations and protect cultural artefacts. This article considers how the National Heritage Board Act (Cap 196A, 1994 Rev Ed), the Planning Act (Cap 232, 1998 Rev Ed), and …

Regulation Of Over-The-Counter Derivatives: A Comparative Study Of Proposals In Singapore And Hong Kong, Chao-Hung Christopher Chen Jan 2013

Regulation Of Over-The-Counter Derivatives: A Comparative Study Of Proposals In Singapore And Hong Kong, Chao-Hung Christopher Chen

Research Collection Yong Pung How School Of Law

This chapter identifies some of the potential legal and policy issues involved in the future regulation of over-the-counter (OTC) derivatives. First, regulators must be cautious in the regulation and solvency of some mammoth clearing- houses. Second, Singapore and Hong Kong both face challenges in the areas of global regulatory cooperation and extra-territorial regulatory effects. Third, the exact scope of a clearing obligation determines whether there is any regulatory competition or room for regulatory arbitrage in the future. Fourth, there are legal definition problems with the term ‘derivative’ and its sub-categories that must be addressed. Fifth, there are potential privacy and …

Certainty At Last?: A "New" Framework For Electronic Contracting In Singapore, Eliza Mik Jan 2013

Certainty At Last?: A "New" Framework For Electronic Contracting In Singapore, Eliza Mik

Research Collection Yong Pung How School Of Law

Singapore is the first Asian country to accede to the UNCITRAL Convention on the Use of Electronic Communications in International Contracts (“CUECIC” or “Convention”). Upon accession, the Singaporean Electronic Transactions Act (“ETA” or “Act”) was repealed and re-enacted in a modified version, with effect from 1 July 2010. The modified ETA retains the framework of the original ETA but adds or amends certain provisions dealing with electronic contracting to align domestic e-commerce regulations with the Convention. Accordingly, Singapore is not only the first Asian nation to accede to the CUECIC but also the first nation to implement some of its …

Research Collection Yong Pung How School Of Law

SMU Assistant Professor of Law and NMP Eugene Tan analysed the results of the Punggol East by-election and discussed what it signals next for the People’s Action Party (PAP), the Workers’ Party, the opposition in general and Singaporeans. He said that while we should be careful not to extrapolate the results of the Punggol East by-election as being a barometer of national sentiment, the results are nonetheless a useful snapshot of the dynamic political situation. He added that PAP urgently needs to connect more with this existential angst, anxiety and aspirations of voters who feel a growing sense of alienation. …

The introduction of invasive marine species by ships is one of the four most significant threats to the world's oceans.' Global shipping moves over 80% of the world's commodities and transfers approximately 3 to 5 billion tonnes of ballast water each year.^ Every day about 3,000 species of animals and plants are transported around the world in the ballast water of ships, or on their hulls.' Some invasive alien marine species can have serious ecological as well as social and economic impacts."*

Micro-Finance Competition: Motivated Micro-Lenders, Double-Dipping And Default, Brishti Guha, Prabal Roy Chowdhury Jan 2013

Micro-Finance Competition: Motivated Micro-Lenders, Double-Dipping And Default, Brishti Guha, Prabal Roy Chowdhury

Research Collection School Of Economics

We develop a tractable model of competition among motivated MFIs. We find that equilibria may or may not involve double-dipping (and consequently default), with there being double-dipping whenever the MFIs are very profit-oriented. Moreover, in an equilibrium with double-dipping, borrowers who double-dip are actually worse off compared to those who do not. Further, for intermediate levels of motivation, there can be multiple equilibria, with a doubledipping equilibrium co-existing with a no default equilibrium. Interestingly, an increase in MFI competition can lower efficiency, as well as increase the extent of double-dipping and default. Further, the interest rates may go either way, …

Research Collection Lee Kong Chian School Of Business

This paper examines the aftermarket performance of initial public offerings (IPOs) and explores the underpricing of IPOs in an Asian emerging equity market using a comprehensive sample of IPOs. Our findings suggest that there exist a significant underpricing. Specifically, new issues have been offered at an average market-adjusted discount of about 20%. The magnitude of IPO underpricing is significantly larger for large firms, older firms and firms with small offering size.

Entropy-Based Analysis And Bioinformatics-Inspired Integration Of Global Economic Information Transfer, Jinkyu Kim, Gunn Kim, Sungbae An, Young-Kyun Kwon, Sungroh Yoon Jan 2013

Entropy-Based Analysis And Bioinformatics-Inspired Integration Of Global Economic Information Transfer, Jinkyu Kim, Gunn Kim, Sungbae An, Young-Kyun Kwon, Sungroh Yoon

Research Collection School Of Economics

The assessment of information transfer in the global economic network helps to understand the current environment and the outlook of an economy. Most approaches on global networks extract information transfer based mainly on a single variable. This paper establishes an entirely new bioinformatics-inspired approach to integrating information transfer derived from multiple variables and develops an international economic network accordingly. In the proposed methodology, we first construct the transfer entropies (TEs) between various intra- and inter-country pairs of economic time series variables, test their significances, and then use a weighted sum approach to aggregate information captured in each TE. Through a …

Estimation Of Monthly Volatility: An Empirical Comparison Of Realized Volatility, Garch And Acd-Icv Methods, Shouwei Liu, Yiu Kuen Tse Jan 2013

Estimation Of Monthly Volatility: An Empirical Comparison Of Realized Volatility, Garch And Acd-Icv Methods, Shouwei Liu, Yiu Kuen Tse

Research Collection School Of Economics

We apply the ACD-ICV method proposed by Tse and Yang (2011) for the estimation of intraday volatility to estimate monthly volatility, and empirically compare this method against the realized volatility (RV) and generalized autoregressive conditional heteroskedasticity (GARCH) methods. Our Monte Carlo results show that the ACD-ICV method performs well against the other two methods. Evidence on the Chicago Board Options Exchange volatility index (VIX) shows that it predicts the ACD-ICV volatility estimates better than it predicts the RV estimates. While the RV method is popular for the estimation of monthly volatility, its performance is inferior to the GARCH method.

Can A Financial Conditions Index Guide Monetary Policy? The Case Of Singapore, Hwee Kwan Chow Jan 2013

Can A Financial Conditions Index Guide Monetary Policy? The Case Of Singapore, Hwee Kwan Chow

Research Collection School Of Economics

In this study, we explore the issue of whether a financial conditions index can serve as a useful guide to monetary policy in the context of Singapore. To this end, we construct an index that comprises not only the usual monetary variables like interest rates, exchange rates and credit expansions but also asset prices such as stock prices and house prices. The choice of these constituent series is motivated by the role they play in the monetary transmission mechanism with consideration given to the key role leverage plays in modern business cycles and the risk-taking channel magnified by the prolonged …

Ex Post Destruction In The Hold-Up Problem, Huan Wang, Juyuan Zhang, Yi Zhang Jan 2013

Ex Post Destruction In The Hold-Up Problem, Huan Wang, Juyuan Zhang, Yi Zhang

Research Collection School Of Economics

We investigate whether or not ex post destruction can solve the hold-up problem. After clarifying the difference between ex post destruction and nontrade when negotiation breaks down, we show that the option of ex post destruction is not sufficient to enhance ex ante efficiency. In particular, only if the information about the spitefulness of the supplier is coarse enough, will the option of ex post destruction alleviate the inefficiency of underinvestment caused by the hold-up problem.
