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.

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 …

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.

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.

Serials Renewal Cycle: Doing It The Smu (A Different U) Way!, Kai Leong Heng Feb 2015

Serials Renewal Cycle: Doing It The Smu (A Different U) Way!, Kai Leong Heng

Research Collection Library

Academic libraries typically renew their serials subscriptions (Individual print and/or online titles) annually by comparing prices, availability and service terms proposed by different subscription agents. In Singapore (and possibly other countries in the region), we have only up to 3 (active and competing) subscription agents to choose from. At Singapore Management University (SMU), the library maintains about 500 serials titles. The “legacy” practice had been to split the order between the two of larger agents and designate a staff each to take charge of related operational matters. This session will present a different approach in the serials renewal cycle which …

Income Smoothing Due To Unemployment Concerns, Jeffrey Ng, Tharindra Ranasinghe, Guifeng Shi, I-Hwa Yang Feb 2015

Income Smoothing Due To Unemployment Concerns, Jeffrey Ng, Tharindra Ranasinghe, Guifeng Shi, I-Hwa Yang

Research Collection School Of Accountancy

Economic theory predicts that top executives and lower-level employees have incentives to smooth income due to compensating wage differential costs and fear of job loss, respectively. Following Agrawal and Matsa (JFE, 2013) who rely on exogenous variations in unemployment insurance benefits to examine how unemployment concerns affect corporate leverage, we examine the link between such benefits and income smoothing. We find that when unemployment insurance benefits are higher and concerns about unemployment are hence lower, there is less income smoothing. This relation is stronger when employees face higher unemployment risk and weaker when the firms’ information and internal control environments …

Use Of A High-Value Social Audience Index For Target Audience Identification On Twitter, Siaw Ling Lo, David Cornforth, Raymond. Chiong

Research Collection School Of Computing and Information Systems

With the large and growing user base of social media, it is not an easy feat to identify potential customers for business. This is mainly due to the challenge of extracting commercially viable contents from the vast amount of free-form conversations. In this paper, we analyse the Twitter content of an account owner and its list of followers through various text mining methods and segment the list of followers via an index. We have termed this index as the High-Value Social Audience (HVSA) index. This HVSA index enables a company or organisation to devise their marketing and engagement plan according …

Textualizing Cultures: Thinking Beyond The Mit Controversy, William A. Callahan

Research Collection School of Social Sciences

This essay examines how the MIT Controversy hardened identities in terms of the time worn template of geopolitical conflict of national stereotypes. It critically analyzes the Chinese students’ response to the “Visualizing Cultures” project by putting it in the context of the PRC’s patriotic education policy that securitizes culture by focusing on identity as difference in a zero-sum game that distinguishes civilization from barbarism, and China from the rest of the world. It critically analyzes the professors response to the controversy by highlighting how meaning is not only produced by the author; it is also consumed by various audiences that …

Review Synthesis For Micro-Review Summarization, Thanh-Son Nguyen, Hady W. Lauw, Panayiotis Tsaparas

Research Collection School Of Computing and Information Systems

Micro-reviews is a new type of user-generated content arising from the prevalence of mobile devices and social media in the past few years. Micro-reviews are bite-size reviews (usually under 200 characters), commonly posted on social media or check-in services, using a mobile device. They capture the immediate reaction of users, and they are rich in information, concise, and to the point. However, the abundance of micro-reviews, and their telegraphic nature make it increasingly difficult to go through them and extract the useful information, especially on a mobile device. In this paper, we address the problem of summarizing the micro-reviews of …

When Do Subordinates Commit To Their Supervisors? Different Effects Of Perceived Supervisor Integrity And Support On Chinese And American Employees, Chi-Ying Cheng, Ding-Yu Jiang, Bor-Shiuan Cheng, Jean H. Riley, Chin-Kang Jen Feb 2015

When Do Subordinates Commit To Their Supervisors? Different Effects Of Perceived Supervisor Integrity And Support On Chinese And American Employees, Chi-Ying Cheng, Ding-Yu Jiang, Bor-Shiuan Cheng, Jean H. Riley, Chin-Kang Jen

Research Collection School of Social Sciences

While subordinates' commitment to the supervisor is highly desirable, the routes to achieve this might vary in different cultures. Drawing on the theories of leader–member exchange (LMX) and cultural logic, this study posits different interaction effects for subordinates' perceived supervisor integrity and support on commitment to the supervisor in cultures with different expectations of personal integrity. The results indicate that an additive effect can be observed for American subordinates: perceived supervisor support increases commitment to the supervisor to a greater extent when a high degree of supervisor integrity is also perceived. In contrast, a compensatory effect can be observed for …

The Federalist Provenance Of The Principle Of Privacy, Elvin T. Lim Feb 2015

The Federalist Provenance Of The Principle Of Privacy, Elvin T. Lim

Research Collection School of Social Sciences

The right to privacy is the centerpiece of modern liberal constitutional thought in the United States. But liberals rarely invoke “the Founding” to justify this right, as if conceding that the right to privacy was somehow a radical departure from “original meaning,” perhaps pulled out of the hat by “activist” judges taking great interpretive liberties with the constitutional text. Far from being an unorthodox and modern invention, I argue here that privacy is a principle grounded in the very architecture of the Constitution as enumerated in its Articles, perhaps even more so than in particular sections of the Bill of …

Multiscale Modeling And Evaluation Of Urban Surface Energy Balance In The Phoenix Metropolitan Area, Stephen R. Shaffer, Winston T. L. Chow, Matei Georgescu, Peter Hyde, Darrel Jenerette, Alex Mahalov, M. Moustaoui, Benjamin Lyle Ruddell

Research Collection School of Social Sciences

Physical mechanisms of incongruency between observations and Weather Research and Forecasting (WRF) Model predictions are examined. Limitations of evaluation are constrained by (i) parameterizations of model physics, (ii) parameterizations of input data, (iii) model resolution, and (iv) flux observation resolution. Observations from a new 22.1-m flux tower situated within a residential neighborhood in Phoenix, Arizona, are utilized to evaluate the ability of the urbanized WRF to resolve finescale surface energy balance (SEB) when using the urban classes derived from the 30-m-resolution National Land Cover Database. Modeled SEB response to a large seasonal variation of net radiation forcing was tested during …

Infrastructure Provision, Gender And Poverty In Indian Slums, Prithi Parikh, Kun Fu, Himanshu Parikh, Allan Mcrobie, Gerard George Feb 2015

Infrastructure Provision, Gender And Poverty In Indian Slums, Prithi Parikh, Kun Fu, Himanshu Parikh, Allan Mcrobie, Gerard George

Research Collection Lee Kong Chian School Of Business

We examine the relationship between infrastructure provision and poverty alleviation by analyzing 500 interviews conducted in serviced and non-serviced slums in India. Using a mixed-method approach of qualitative analysis and regression modeling, we find that infrastructure was associated with a 66% increase in education among females. Service provision increased literacy by 62%, enhanced income by 36%, and reduced health costs by 26%. Evidence suggests that a gender-sensitive consideration of infrastructure is necessary and that a ‘one-size-fits-all’ approach will not suffice. We provide evidence that infrastructure investment is critical for well-being of slum dwellers and women in particular.
