Retirement Security In Oregon, Jeff Renfro, Marisol Cáceres, Peter Hulseman Mar 2015

Retirement Security In Oregon, Jeff Renfro, Marisol Cáceres, Peter Hulseman

Northwest Economic Research Center Publications and Reports

By expanding access to retirement savings plans, a state-sponsored program for workers should increase the overall level of participation, and, ultimately, increase retirement fund income. The over 400,000 new enrollees estimated by this study suggests that these programs can have large impacts.

A Game Of Spot The Difference: Librarians, Repository Managers, And Publishers, Phill Jones, Andrew Wesolek, David Scherer, Charles Watkinson Mar 2015

A Game Of Spot The Difference: Librarians, Repository Managers, And Publishers, Phill Jones, Andrew Wesolek, David Scherer, Charles Watkinson

Presentations

Many library publishing programs emerged from institutional repositories. This close relationship has led to the emergence of content platforms that are designed to operate under either use case, however, the missions and requirements of the two types of program differ. A repository for example, may be primarily concerned with the curation, preservation, and accessibility of their institution’s academic output whilst publishers must also concern themselves with external discoverability, search engine optimization, getting indexed in abstract databases and marketing their journals. In this session, you will hear from three successful library publishers who have embraced this external facing aspect of publishing. …

How "Situational" Is Judgment In Situational Judgment Tests?, Stefan Krumm, Filip Lievens, Joachim Huffmeier, Anastasiya A. Lipnevich, Hanna Bendels, Gudio Hertel Mar 2015

How "Situational" Is Judgment In Situational Judgment Tests?, Stefan Krumm, Filip Lievens, Joachim Huffmeier, Anastasiya A. Lipnevich, Hanna Bendels, Gudio Hertel

Research Collection Lee Kong Chian School Of Business

Whereas situational judgment tests (SJTs) have traditionally been conceptualized as low-fidelity simulations with an emphasis on contextualized situation descriptions and context-dependent knowledge, a recent perspective views SJTs as measures of more general domain (context-independent) knowledge. In the current research, we contrasted these 2 perspectives in 3 studies by removing the situation descriptions (i.e., item stems) from SJTs. Across studies, the traditional contextualized SJT perspective was not supported for between 43% and 71% of the items because it did not make a significant difference whether the situation description was included or not for these items. These results were replicated across construct …

Self-Exciting Jumps, Learning, And Asset Pricing Implications, Andras Fulop, Junye Li, Jun Yu Mar 2015

Self-Exciting Jumps, Learning, And Asset Pricing Implications, Andras Fulop, Junye Li, Jun Yu

Research Collection School Of Economics

The paper proposes a self-exciting asset pricing model that takes into account co-jumps between prices and volatility and self-exciting jump clustering. We employ a Bayesian learning approach to implement real-time sequential analysis. We find evidence of self-exciting jump clustering since the 1987 market crash, and its importance becomes more obvious at the onset of the 2008 global financial crisis. We also find that learning affects the tail behaviors of the return distributions and has important implications for risk management, volatility forecasting, and option pricing.

Institutional Entrepreneurship, Governance And Poverty: Insights From Emergency Medical Response Services In India, Gerard George, Rekha Rao-Nicholson, Christopher Corbishley, Rahul Bansal Mar 2015

Institutional Entrepreneurship, Governance And Poverty: Insights From Emergency Medical Response Services In India, Gerard George, Rekha Rao-Nicholson, Christopher Corbishley, Rahul Bansal

Research Collection Lee Kong Chian School Of Business

We present an in-depth case study of GVK Emergency Management and Research Institute, an Indian public–private partnership (PPP), which successfully brought emergency medical response to remote and urban settings. Drawing insights from the case, we investigate how the organization established itself through institutional entrepreneurship using a process conceptualized as opportunity framing, entrenchment, and propagation. The case and context highlight the need for innovation in organizational design and governance modes to create a new opportunity that connects state actors, private healthcare providers, and the public at large. We consider the role of open innovation and novel business models in creating these …

Enriching Surveys With Supplementary Data And Its Application To Studying Wage Regression, Denis H. Y. Leung, Ken Yamada, Biao Zhang Mar 2015

Enriching Surveys With Supplementary Data And Its Application To Studying Wage Regression, Denis H. Y. Leung, Ken Yamada, Biao Zhang

Research Collection School Of Economics

We consider the problem of supplementing survey data with additional information from a population. The framework we use is very general; examples are missing data problems, measurement error models and combining data from multiple surveys. We do not require the survey data to be a simple random sample of the population of interest. The key assumption we make is that there exists a set of common variables between the survey and the supplementary data. Thus, the supplementary data serve the dual role of providing adjustments to the survey data for model consistencies and also enriching the survey data for improved …

Lm Tests Of Spatial Dependence Based On Bootstrap Critical Values, Zhenlin Yang Mar 2015

Lm Tests Of Spatial Dependence Based On Bootstrap Critical Values, Zhenlin Yang

Research Collection School Of Economics

To test the existence of spatial dependence in an econometric model, a convenient test is the Lagrange Multiplier (LM) test. However, evidence shows that, in finite samples, the LM test referring to asymptotic critical values may suffer from the problems of size distortion and low power, which become worse with a denser spatial weight matrix. In this paper, residual-based bootstrap methods are introduced for asymptotically refined approximations to the finite sample critical values of the LM statistics. Conditions for their validity are clearly laid out and formal justifications are given in general, and in detail under several popular spatial LM …

Asymptotic Theory For Linear Diffusions Under Alternative Sampling Scheme, Qiankun Zhou, Jun Yu Mar 2015

Asymptotic Theory For Linear Diffusions Under Alternative Sampling Scheme, Qiankun Zhou, Jun Yu

Research Collection School Of Economics

The asymptotic distributions of the maximum likelihood estimator of the persistence parameter are developed in a linear diffusion model under three sampling schemes, long-span, in-fill and double. Simulations suggest that the in-fill asymptotic distribution gives a more accurate approximation to the finite sample distribution than the other two distributions. An empirical application highlights the difference in unit root testing based on the alternative asymptotic distributions.

Bias Correction For Fixed Effects Spatial Panel Data Models, Zhenlin Yang, Jihai Yu, Shew Fan Liu Mar 2015

Bias Correction For Fixed Effects Spatial Panel Data Models, Zhenlin Yang, Jihai Yu, Shew Fan Liu

Research Collection School Of Economics

This paper examines the finite sample properties of the quasi maximum likelihood (QML) estimators of the fixed effects spatial panel data (FE-SPD) models of Lee and Yu (2010). Following the general bias correction methods recently developed by Yang (2015), we derive up to third-order bias corrections for the QML estimators of the FE-SPD model, and propose a simple bootstrap method for their practical implementation. Monte Carlo results reveal that the QML estimators of the spatial parameters can be quite biased and that a second-order bias correction effectively removes the bias. The validity of the bootstrap method is established. Variance corrections …

Fertility And Rural Electrification In Bangladesh, Tomoki Fujii, Abu S. Shonchoy Mar 2015

Fertility And Rural Electrification In Bangladesh, Tomoki Fujii, Abu S. Shonchoy

Research Collection School Of Economics

We use a panel dataset from Bangladesh to examine the relationship between fertility and the adoption of electricity with the latter instrumented by infrastructure development and the quality of service delivery. We find that the adoption of electricity reduces fertility, and this impact is more pronounced when the household already has two or more children. This observation can be explained by a simple household model of time use, in which adoption of electricity affects only the optimal number of children but not necessarily current fertility behavior if the optimal number has not yet been reached.

Expanding Context To Redefine Theories: Africa In Management Research, Gerard George Mar 2015

Expanding Context To Redefine Theories: Africa In Management Research, Gerard George

Research Collection Lee Kong Chian School Of Business

As a scholarly field matures, theories emerge that guide paradigms and shape consensus in academic discourse. Management theories reflect a shared consensus on how individual behaviors or organizational actions result in a certain set of outcomes and under specific conditions. Clearly, theory is paramount to guiding whether models of potential relationships bear out and how and why we would expect a relationship or specific outcome. Yet much of this theory is derived from cumulative empirical evidence from a ‘context’ that has remained a silent partner in our quest for a theoretical contribution. A growing number of papers emphasize the theoretical …

Questionnaire Design Effects In Climate Change Surveys: Implications For The Partisan Divide, Jonathon P. Schuldt, Sungjong Roh, Norbert Schwarz Mar 2015

Questionnaire Design Effects In Climate Change Surveys: Implications For The Partisan Divide, Jonathon P. Schuldt, Sungjong Roh, Norbert Schwarz

Research Collection Lee Kong Chian School Of Business

Despite strong agreement among scientists, public opinion surveys reveal wide partisan disagreement on climate issues in the united States. we suggest that this divide may be exaggerated by questionnaire design variables. Following a brief literature review, we report on a national survey experiment involving U.S. Democrats and Republicans (n = 2,041) (fielded August 25–September 5, 2012) that examined the effects of question wording and order on the belief that climate change exists, perceptions of scientific consensus, and support for limiting greenhouse gas emissions. wording a questionnaire in terms of “global warming” (versus “climate change”) reduced Republicans’ (but not Democrats’) existence …

On The Effectiveness Of Housing Purchase Restriction Policy In China: A Difference In Difference Approach, Jerry X. Cao, Bihong Huang, Rose Neng Lai Mar 2015

On The Effectiveness Of Housing Purchase Restriction Policy In China: A Difference In Difference Approach, Jerry X. Cao, Bihong Huang, Rose Neng Lai

Research Collection Lee Kong Chian School Of Business

The Chinese government imposed the purchase restriction policy to rein in the housing bubble in 2010. Using a two-stage difference-in-difference approach and a comprehensive dataset covering the real estate markets across 70 cities, we find that the policy triggered substantial decline in the property price and transaction volume. Cities having higher reliance on real estate sector for fiscal revenue and economic growth experienced greater decline in housing prices following the policy implementation. However, the policy had no measurable effects on the nationwide construction boom, hinting the ineffectiveness of the policy to correct the housing bubble.

Managerial Segmentation Of Service Offerings In Work Commuting, Mti Report Wp 12-02, Steven Silver Mar 2015

Managerial Segmentation Of Service Offerings In Work Commuting, Mti Report Wp 12-02, Steven Silver

Mineta Transportation Institute

Methodology to efficiently segment markets for public transportation offerings has been introduced and exemplified in an application to an urban travel corridor in which high tech companies predominate. The principal objective has been to introduce and apply multivariate methodology to efficiently identify segments of work commuters and their demographic identifiers. A set of attributes in terms of which service offerings could be defined was derived from background studies and focus groups of work commuters in the county. Adaptive choice conjoint analysis was used to derive the importance weights of these attributes in available service offering to these commuters. A two-stage …

Qml Estimation Of Dynamic Panel Data Models With Spatial Errors, Liangjun Su, Zhenlin Yang Mar 2015

Qml Estimation Of Dynamic Panel Data Models With Spatial Errors, Liangjun Su, Zhenlin Yang

Research Collection School Of Economics

We propose quasi maximum likelihood (QML) estimation of dynamic panel models with spatial errors when the cross-sectional dimension n is large and the time dimension T is fixed. We consider both the random effects and fixed effects models, and prove consistency and derive the limiting distributions of the QML estimators under different assumptions on the initial observations. We propose a residual-based bootstrap method for estimating the standard errors of the QML estimators. Monte Carlo simulation shows that both the QML estimators and the bootstrap standard errors perform well in finite samples under a correct assumption on initial observations, but may …

The Changing And Unchanged Nature Of Inequality And Seniority In Japan, Ken Yamada, Daiji Kawaguchi Mar 2015

The Changing And Unchanged Nature Of Inequality And Seniority In Japan, Ken Yamada, Daiji Kawaguchi

Research Collection School Of Economics

Wage inequality declined in the 1990s, while it increased in the 2000s for full-time male workers in Japan. We find that a decreased return to firm-specific human capital, which has been neglected in previous empirical analyses of inequality, is a key factor preventing a rise in wage inequality during the prolonged period of economic stagnation, known as Japan’s lost decades. We also find that, while changes in returns to general and specific human capital contributed to narrowing wage inequality in the 1990s and widening wage inequality in the 2000s, a significant fraction of the increase in wage inequality in the …

Social Transformation, Group Reputation, And Reputation Matching, Huan Wang, Yi Zhang Mar 2015

Social Transformation, Group Reputation, And Reputation Matching, Huan Wang, Yi Zhang

Research Collection School Of Economics

Unlike in small communities where one can strategically interact with another according to the latter’s individual reputation, players in complex societies often have to interact with strangers whose individual reputations cannot be easily acquired. They often have to infer their counterparts’ characteristics from the latters’ group reputation to simplify decision making. We provide a game theoretical model of reputation matching concerning corruption during social transformation. We show that the regime change from acquaintance matching to anonymous matching tends to cause rampant corruption and the effectiveness of anti-corruption policies is non-monotonic with respect to the supervision efforts.

Parent And Family Outcomes Of Peers: A Social Skills Intervention For Adolescents With Autism Spectrum Disorder, Jeffrey S. Karst, Amy V. Van Hecke, Audrey M. Carson, Sheryl Jayne Stevens, Kirsten A. Schohl, Bridget Dolan

Psychology Faculty Research and Publications

Raising a child with an Autism Spectrum Disorder (ASD) is associated with increased family chaos and parent distress. Successful long-term treatment outcomes are dependent on healthy systemic functioning, but the family impact of treatment is rarely evaluated. The Program for the Education and Enrichment of Relational Skills (PEERS) is a social skills intervention designed for adolescents with high-functioning ASD. This study assessed the impact of PEERS on family chaos, parenting stress, and parenting self-efficacy via a randomized, controlled trial. Results suggested beneficial effects for the experimental group in the domain of family chaos compared to the waitlist control, while parents …

Language Use In Consultation: Can “We” Help Teachers And Students?, Daniel S. Newman, Meaghan C. Guiney, Courteney A. Barrett

Psychology Faculty Publications

Analyzing the use of function words such as pronouns in conversation is an increasingly popular approach in social psychology, but has not yet been applied to the study of school-based consultation. The two central purposes of this study were to: (1) examine how language is used by consultants-in-training (CITs) and consultees within a collaborative model of consultation, and (2) to explore the relation between language use and the collaborative relationship, consultee outcomes, and client outcomes. Analyses focused on CITs’ (n = 18) and consultees’ (n = 18) use of pronouns in a problem identification and analysis (PID/PA) …

Low-vision and blind bus riders often rely on known physical landmarks to help locate and verify bus stoplocations (e.g., by searching for an expected shelter, bench, or newspaper bin). However, there are currentlyfew, if any, methods to determine this information a priori via computational tools or services. In thisarticle, we introduce and evaluate a new scalable method for collecting bus stop location and landmarkdescriptions by combining online crowdsourcing and Google Street View (GSV). We conduct and report onthree studies: (i) a formative interview study of 18 people with visual impairments to inform the designof our crowdsourcing tool, (ii) a comparative …

Nirmal: Automatic Identification Of Software Relevant Tweets Leveraging Language Model, Abishek Sharma, Yuan Tian, David Lo Mar 2015

Nirmal: Automatic Identification Of Software Relevant Tweets Leveraging Language Model, Abishek Sharma, Yuan Tian, David Lo

Research Collection School Of Computing and Information Systems

Twitter is one of the most widely used social media platforms today. It enables users to share and view short 140-character messages called 'tweets'. About 284 million active users generate close to 500 million tweets per day. Such rapid generation of user generated content in large magnitudes results in the problem of information overload. Users who are interested in information related to a particular domain have limited means to filter out irrelevant tweets and tend to get lost in the huge amount of data they encounter. A recent study by Singer et al. found that software developers use Twitter to …

Foreign Precedents In Constitutional Adjudication By The Supreme Court Of Singapore, 1963-2013, Jack Tsen-Ta Lee Mar 2015

Foreign Precedents In Constitutional Adjudication By The Supreme Court Of Singapore, 1963-2013, Jack Tsen-Ta Lee

Research Collection Yong Pung How School Of Law

This article surveys the use of foreign precedents in constitutional adjudication by the Supreme Court of Singapore for over a half century during the terms of the first three Chief Justices—Wee Chong Jin (1963–1990), Yong Pung How (1990–2006), and Chan Sek Keong (2006–2012)—and the first year in office of the fourth Chief Justice, Sundaresh Menon (2012–2013). It concludes that while judges have always cited foreign case law, they have only actually applied foreign cases where the wording of the Constitution and the constitutional arrangements in Singapore are fairly analogous to the constitutional texts and arrangements upon which the cases were …

East Asian Trusts At The Crossroads, Ying Chieh Wu Mar 2015

East Asian Trusts At The Crossroads, Ying Chieh Wu

Research Collection Yong Pung How School Of Law

The purpose of this article is to scrutinize the legal structure of trusts in Japan, SouthKorea and Taiwan. The so-called infrastructure of the private law of these jurisdictions is rooted in theRoman-Germanic basis, which adopts dichotomous system in respect of that area of privatelaw dealing with property: the law of property and that of obligation. However,the adoption of the trust has caused some problems. Though controversial, thecontract-based view seems to be the majority view in the East Asian civiljurisdictions, yet the property-based view dominates the commonlaw world. However, being influenced by common law, the property-approach isalso asserted by some commentators …
