Future Fiscal And Budgetary Shocks, Hian Teck Hoon, Edmund S. Phelps Nov 2008

Future Fiscal And Budgetary Shocks, Hian Teck Hoon, Edmund S. Phelps

Research Collection School Of Economics

We study the effects of future tax and budgetary shocks in a non-monetary and possibly non-Ricardian economy. An (unanticipated) temporary labor tax cut to be effective on a given future date—a delayed “debt bomb”—causes at once a drop in the (unit) value placed on the firms' business asset, the customer, with the result that share prices, the hourly wage, and employment drop in tandem. This paradox of reduced activity through announcement of future “stimulus” does not hinge on an upward jump of long interest rates. A future tax-rate cut lacking a “sunset” provision has the same negative effects.

Directed Altruism And Enforced Reciprocity In Social Networks, Stephen Leider, Markus M. Mobius, Tanya S. Rosenblat, Quoc-Anh Do Nov 2008

Directed Altruism And Enforced Reciprocity In Social Networks, Stephen Leider, Markus M. Mobius, Tanya S. Rosenblat, Quoc-Anh Do

Research Collection School Of Economics

We conducted online field experiments in large real-world social networks in order to decompose prosocial giving into three components: (1) baseline altruism toward randomly selected strangers, (2) directed altruism that favors friends over random strangers, and (3) giving motivated by the prospect of future interaction. Directed altruism increases giving to friends by 52% relative to random strangers, whereas future interaction effects increase giving by an additional 24% when giving is socially efficient. This finding suggests that future interaction affects giving through a repeated game mechanism where agents can be rewarded for granting efficiency-enhancing favors. We also find that subjects with …

Testing For Parameter Stability In Quantile Regression Models, Liangjun Su, Zhijie Xiao Nov 2008

Testing For Parameter Stability In Quantile Regression Models, Liangjun Su, Zhijie Xiao

Research Collection School Of Economics

We propose a test for structural change of conditional distribution in dynamic regression models. The test is constructed based on time series regression quantile estimates and complements conventional parameter instability tests in least-square type regression models. Asymptotic distribution for our test under the null hypothesis is derived.

Can A Representative Agent Model Represent A Heterogeneous Agent Economy?, Sungbae An, Yongsung Chang, Sun-Bin Kim Nov 2008

Can A Representative Agent Model Represent A Heterogeneous Agent Economy?, Sungbae An, Yongsung Chang, Sun-Bin Kim

Research Collection School Of Economics

Accounting for observed fluctuations in aggregate employment, consumption, and real wage using the optimality conditions of a representative household requires preferences that are incompatible with economic priors. In order to reconcile theory with data, we construct a model with heterogeneous agents whose decisions are difficult to aggregate because of incomplete capital markets and the indivisible nature of labor supply. If we were to explain the model-generated aggregate time series using decisions of a stand-in household, such a household must have a nonconcave or unstable utility as is often found with the aggregate US data.

Prison’S Spoilt Identities: Racially Structured Realities Within And Beyond, Nafis Hanif Nov 2008

Prison’S Spoilt Identities: Racially Structured Realities Within And Beyond, Nafis Hanif

Research Collection School of Social Sciences

This article begins by seeking an explanation for the solidarity between Malay inmates and guards in perpetrating abusive and discriminatory treatment towards Malay transvestites. In the course of explaining an empirical phenomenon in the Singapore prison, this article has examined Singapore's history and ethnic demography, the ethnic Malay minority's lack of socio-economic development and modernisation vis-a-vis the ethnic Chinese majority, geo-politics, the ideology and strategic choices of the state's political elite and their implications for inter-ethnic interactions between Malays and Chinese. As this article will argue, prison culture, rather than being divorced from larger society, is in effect able to …

Interactive Effects Of Multicultural Experiences And Openness To Experience On Creativity, Angela K.-Y. Leung, Chi-Yue Chiu Nov 2008

Interactive Effects Of Multicultural Experiences And Openness To Experience On Creativity, Angela K.-Y. Leung, Chi-Yue Chiu

Research Collection School of Social Sciences

Extensiveness of multicultural experiences and Openness to Experience were used to predict European American undergraduates' performance on two measures of creative potential: (a) generation of unusual uses of garbage bags and (b) retrieval of nonprototypical or normatively inaccessible exemplars in the conceptual domain of occupation. The results showed that having extensive multicultural experiences predicted better performance on both measures of creative potential only among participants who were open to experience. Among those who were not open, having more extensive multicultural experiences was associated with a lower level of creative potential. Implications of these findings for promoting creativity in schools are …

Growth Is Good For Whom, When, How? Economic Growth And Poverty Reduction In Exceptional Cases, John A. Donaldson Nov 2008

Growth Is Good For Whom, When, How? Economic Growth And Poverty Reduction In Exceptional Cases, John A. Donaldson

Research Collection School of Social Sciences

Economic growth and liberal economic policies often help the poor, but what about the numerous cases in which they do not? This article analyzes two types of cases: those in which income growth of the poor was significantly lower than expectations (negative exceptions) and those in which income growth of the poor significantly exceeded expectations (positive exceptions). Insights from these cases inform our theoretical understanding of poverty reduction. In addition, this article contributes a typology of strategies used in these cases, including alternative pathways to economic growth and neoliberal prescriptions for poverty reduction.

Changes In Women's Choice Of Dress Across The Ovulatory Cycle: Naturalistic And Laboratory Task-Based Evidence, Kristina M. Durante, Norman P. Li, Martie G. Haselton Nov 2008

Changes In Women's Choice Of Dress Across The Ovulatory Cycle: Naturalistic And Laboratory Task-Based Evidence, Kristina M. Durante, Norman P. Li, Martie G. Haselton

Research Collection School of Social Sciences

The authors tested the prediction that women prefer clothing that is more revealing and sexy when fertility is highest within the ovulatory cycle. Eighty-eight women reported to the lab twice: once on a low-fertility day of the cycle and once on a high-fertility day (confirmed using hormone tests). In each session, participants posed for full-body photographs in the clothing they wore to the lab, and they drew illustrations to indicate an outfit they would wear to a social event that evening. Although each data source supported the prediction, the authors found the most dramatic changes in clothing choice in the …

Connecting The Dots Within: Creative Performance And Identity Integration, Chi-Ying Cheng, Jeffrey Sanchez-Burks, Fion Lee Nov 2008

Connecting The Dots Within: Creative Performance And Identity Integration, Chi-Ying Cheng, Jeffrey Sanchez-Burks, Fion Lee

Research Collection School of Social Sciences

In two studies drawing from social identity theory and the creative-cognition approach, we found that higher levels of identity integration - perceived compatibility between two social identities - predict higher levels of creative performance in tasks that draw on both identity-relevant knowledge domains. Study 1 showed that Asian Americans with higher identity integration were more creative in developing new dishes using a given set of ingredients, but only when both Asian and American ingredients were available. Study 2 showed that female engineers with higher identity integration were more creative in designing a product, but only when the product was targeted …

A Comparative Account Of Statutory Interpretation In Singapore, Yihan Goh Oct 2008

A Comparative Account Of Statutory Interpretation In Singapore, Yihan Goh

Research Collection Yong Pung How School Of Law

In 1993, the Singapore Parliament enacted legislative provisions adapted from Australian legislation directing, inter alia, that the courts apply the purposive approach in statutory interpretation. Those provisions also allowed for the extended use of extrinsic materials in the interpretative process. Fifteen years on, there is now a considerable body of Singapore case law to which a meaningful analysis may be undertaken. Indeed, from an initially cautious application of the enacted legislation, the courts began to read the enactments expansively, eventually providing for a statutory interpretation regime that is largely free of the confines of old. Nonetheless, the Singapore position does …

Unpacking Sources Of Comparative Advantage: A Quantitative Approach, Davin Chor Oct 2008

Unpacking Sources Of Comparative Advantage: A Quantitative Approach, Davin Chor

Research Collection School Of Economics

This paper develops an approach for quantifying the relative importance of different sources of comparative advantage for country welfare in a global trade equilibrium. To explain the pattern of specialization, I present a multi-country, perfectly-competitive Ricardian model that extends Eaton and Kortum (2002) to predict industry trade flows. In this framework, comparative advantage is determined by the interaction of country and industry characteristics, with countries specializing in industries whose specific production needs they are best able to meet with their factor endowments, institutional environment, and technological strengths. I estimate the model parameters using a large dataset of bilateral trade flows, …

Schooling And Political Participation Revisited, Davin Chor, Filipe R. Campante Oct 2008

Schooling And Political Participation Revisited, Davin Chor, Filipe R. Campante

Research Collection School Of Economics

We investigate how the link between individual schooling and political participation is a ected by country characteristics which determine the relative productivity of human capital in political versus production activities. In our model, individuals face an e ort-allocation decision over the use of their human capital. Focusing on the role played by country factor endowments, we show that the abundance of a factor that is used in the least (respectively most) human capital-intensive sector will increase (respectively decrease) both: (i) the level of individual political participation; and (ii) the responsiveness of individual political participation to increases in human capital. We …

The More Kids, The Less Mom's Divvy: Impact Of Childbirth On Intrahousehold Resource Allocation, Tomoki Fujii, Ryuichiro Ishikawa Oct 2008

The More Kids, The Less Mom's Divvy: Impact Of Childbirth On Intrahousehold Resource Allocation, Tomoki Fujii, Ryuichiro Ishikawa

Research Collection School Of Economics

We investigate how the impact of childbirth on intrahousehold allocation for married Japanese couples. We developed reduced‐form and structural‐form specifications from a unified theoretical framework. Under a weak set of assumptions, we can focus on private goods to track the changes in intrahousehold resource allocation. Our estimation results show that that allocation of resources within household tend to move to the disadvantage of women after a childbirth. One additional child is associated with a reduction in the wife's private expenditure share. Our estimation results reject the income-pooling hypothesis, and show that women are more risk averse than men.

The Labor Market Of Italian Politicians, Antonio Merlo, Vincenzo Galasso, Massimiliano Landi, Andrea Mattozzi Oct 2008

The Labor Market Of Italian Politicians, Antonio Merlo, Vincenzo Galasso, Massimiliano Landi, Andrea Mattozzi

Research Collection School Of Economics

We analyze the career profiles of Italian legislators in the post-war period. Using a unique, newly collected dataset that contains detailed information on all the politicians who have been elected to the Italian Parliament between 1948 and 2008, we address a number of important issues that pertain to their career paths prior to election to Parliament, their parliamentary careers, and their post-Parliament employment. Our data span two institutional regimes: Italy's First Republic (1948-1994) and the Second Republic (1994-present), characterized by different electoral rules and party structures. We first present a brief overview of the Italian political system. We then provide …

Utility Functions, Future Consumption Targets And Subsistence Thresholds, Ashok Guha, Brishti Guha Oct 2008

Utility Functions, Future Consumption Targets And Subsistence Thresholds, Ashok Guha, Brishti Guha

Research Collection School Of Economics

If the consumer’s risk aversion behavior varies intertemporally and if the risk aversion coefficient on future consumption becomes very large, the consumer tends to aim at a fixed future consumption target. A by-product is a reinterpretation of subsistence theories of consumption.

Impacts Of Information And Communication Technologies On Country Development: Accounting For Area Interrelationships, Robert J. Kauffman, Ajay Kumar Oct 2008

Impacts Of Information And Communication Technologies On Country Development: Accounting For Area Interrelationships, Robert J. Kauffman, Ajay Kumar

Research Collection School Of Computing and Information Systems

Single-item composite indices gauge ICT readiness at the country level but do not represent the direct impact of ICTs on a country's development. This paper describes a new approach to measuring the macrolevel impacts of ICTs across a range of development areas. The indirect effects of one area on others is taken into consideration by a simultaneous equation model that permits the inclusion of multiple development areas. The model is applied to data pertaining to four development areas in 64 countries: trade flows, agricultural productivity, R&D, and quality of life. ICT readiness is found to have a positive association with …

Leveraging Social Context For Searching Social Media, Marc Smith, Vladimir Barash, Lise Getoor, Hady W. Lauw Oct 2008

Leveraging Social Context For Searching Social Media, Marc Smith, Vladimir Barash, Lise Getoor, Hady W. Lauw

Research Collection School Of Computing and Information Systems

The ability to utilize and benefit from today's explosion of social media sites depends on providing tools that allow users to productively participate. In order to participate, users must be able to find resources (both people and information) that they find valuable. Here, we argue that in order to do this effectively, we should make use of a user's "social context". A user's social context includes both their personal social context (their friends and the communities to which they belong) and their community social context (their role and identity in different communities).

The Campaign Value Of Incumbency: A New Solution To The Puzzle Of Less Effective Incumbent Spending, Kenneth Benoit, Michael Marsh Oct 2008

The Campaign Value Of Incumbency: A New Solution To The Puzzle Of Less Effective Incumbent Spending, Kenneth Benoit, Michael Marsh

Research Collection School of Social Sciences

A puzzle in research on campaign spending is that while expenditure is positively related to votes won, this effect is far more strongly, or even exclusively, enjoyed by challengers rather than by incumbents. We unearth a new explanation for the puzzle, focusing on the hidden, yet variable, campaign value of office perquisites which incumbents deploy in their campaigns to win votes. When these variable office benefits are unobserved, then the effect is to make observed incumbent spending less effective than spending by challengers. Using data from the 2002 Irish general election, where incumbency was assigned a variable campaign value and …

Endogenous Transaction Cost, Specialization, And Strategic Alliance, Juyuan Zhang, Yi Zhang Oct 2008

Endogenous Transaction Cost, Specialization, And Strategic Alliance, Juyuan Zhang, Yi Zhang

Research Collection School Of Economics

In property rights theory, firm is an organizational response to reduce transaction cost associated with hold-up of using market mechanism. We claim that strategic alliance { without changing firm boundaries or asset ownership { is another type of organizational response. We construct a model to investigate individual firms' strategic choice on specialization or diversification when producing intermediate products and their further choice of organizational form: autarchy or forming strategic alliance. We introduce fixed learning costs as an indicator of scales of economy and show that only if fixed learning costs are large enough, will firms have incentive to be specialization …

How Well Can We Target Aid With Rapidly Collected Data? Empirical Results For Poverty Mapping From Cambodia, Tomoki Fujii Oct 2008

How Well Can We Target Aid With Rapidly Collected Data? Empirical Results For Poverty Mapping From Cambodia, Tomoki Fujii

Research Collection School Of Economics

We compare commune-level poverty rankings in Cambodia based on three different methods: small-area estimation, principal component analysis using aggregate data, and interviews with local leaders. While they provide reasonably consistent rankings, the choice of the ranking method matters. In order to assess the potential losses from moving away from census-based poverty mapping, we used the concentration curve. Our calculation shows that about three-quarters of the potential gains from geographic targeting may be lost by using aggregate data. The usefulness of aggregate data in general would depend on the cost of data collection.

Validity And Adverse Impact Potential Of Predictor Composite Formation, Wilfried De Corte, Filip Lievens, Paul R. Sackett Sep 2008

Validity And Adverse Impact Potential Of Predictor Composite Formation, Wilfried De Corte, Filip Lievens, Paul R. Sackett

Research Collection Lee Kong Chian School Of Business

Previous research on the validity and adverse impact (AI) of predictor composite formation focused on the merits of regression-based or ad hoc composites. We argue for a broader focus. Ad hoc chosen composites are usually not Pareto-optimal, whereas the regression-based composite represents only one element from the total set of Pareto-optimal composites and can, therefore, provide only limited information on the potential for validity and AI reduction of forming predictor composites when both validity and AI are of concern. In that case, other Pareto-optimal composites may provide a better benchmark to decide on the merits of the predictor composite formation. …

Very Low Fertility In Pacific Asian Countries: Causes And Policy Responses, Paulin Tay Straughan Sep 2008

Very Low Fertility In Pacific Asian Countries: Causes And Policy Responses, Paulin Tay Straughan

Research Collection School of Social Sciences

Only 40 years ago, population experts were still worried about a population explosion that would threaten the future of humanity. Fortunately, while population growth is currently largely under control, sub-Saharan Africa and parts of South Asia still face massive increases with very serious potential consequences. Paradoxically, however, a new problem is emerging, with its key locus in Pacific Asia (the term used in this book to refer to Asian countries with a Pacific littoral). This problem is ultra-low fertility. Japan, Singapore, Taiwan, South Korea, and Hong Kong SAR are among the very lowest-fertility countries in the whole world, and even …

Improving Semiparametric Estimation By Using Surrogate Data, Song Xi Chen, Leung, Denis H. Y., Jin Qin Sep 2008

Improving Semiparametric Estimation By Using Surrogate Data, Song Xi Chen, Leung, Denis H. Y., Jin Qin

Research Collection School Of Economics

The paper considers estimating a parameter beta that defines an estimating function U(y, x, beta) for an outcome variable y and its covariate x when the outcome is missing in some of the observations. We assume that, in addition to the outcome and the covariate, a surrogate outcome is available in every observation. The efficiency of existing estimators for beta depends critically on correctly specifying the conditional expectation of U given the surrogate and the covariate. When the conditional expectation is not correctly specified, which is the most likely scenario in practice, the efficiency of estimation can be severely compromised …

Do Online Reviews Affect Product Sales? The Role Of Reviewer Characteristics And Temporal Effects, Nan Hu, Ling Liu, Jennifer Zhang Sep 2008

Do Online Reviews Affect Product Sales? The Role Of Reviewer Characteristics And Temporal Effects, Nan Hu, Ling Liu, Jennifer Zhang

Research Collection School Of Computing and Information Systems

Online product reviews provided by consumers who previously purchased products have become a major information source for consumers and marketers regarding product quality. This study extends previous research by conducting a more compelling test of the effect of online reviews on sales. In particular, we consider both quantitative and qualitative aspects of online reviews, such as reviewer quality, reviewer exposure, product coverage, and temporal effects. Using transaction cost economics and uncertainty reduction theories, this study adopts a portfolio approach to assess the effectiveness of the online review market. We show that consumers understand the value difference between favorable news and …

The Effective Reach Of Choice Of Law Agreements, Tiong Min Yeo Sep 2008

The Effective Reach Of Choice Of Law Agreements, Tiong Min Yeo

Research Collection Yong Pung How School Of Law

Two fundamental principles relating to party autonomy developed in the recent history of the conflict of laws. Despite initial reservations, the law today takes for granted that the parties’ agreement is nearly conclusive in respect of both their choice of litigation forum and their choice of the law governing the contractual relationship. Meanwhile, the law of obligations – in tort, restitution and equity – has grown apace; disputes between contracting parties today are rarely confined to pure contractual issues. Can contracting parties choose the law to govern non-contractual disputes in cross-border litigation? In the absence of such choice, to what …

Limit Theory For Explosively Cointegrated Systems, Peter C. B. Phillips, Tassos Magdalinos Aug 2008

Limit Theory For Explosively Cointegrated Systems, Peter C. B. Phillips, Tassos Magdalinos

Research Collection School Of Economics

A limit theory is developed for multivariate regression in an explosive cointegrated system. The asymptotic behavior of the least squares estimator of the cointegrating coefficients is found to depend upon the precise relationship between the explosive regressors. When the eigenvalues of the autoregressive matrix Θ are distinct, the centered least squares estimator has an exponential Θn rate of convergence and a mixed normal limit distribution. No central limit theory is applicable here, and Gaussian innovations are assumed. On the other hand, when some regressors exhibit common explosive behavior, a different mixed normal limiting distribution is derived with rate of convergence …
