Housing Wealth Shocks, Home Equity Withdrawal, And The Claiming Of Social Security Retirement Benefits, Naqun Huang, Li Jing, Amanda Ross Apr 2022

Housing Wealth Shocks, Home Equity Withdrawal, And The Claiming Of Social Security Retirement Benefits, Naqun Huang, Li Jing, Amanda Ross

Research Collection School Of Economics

This paper examines the impact of changes in house prices on when eligible individuals start receiving Social Security benefits. If house prices increase, financially constrained households may draw upon the additional home equity to finance expenses and delay receipt of Social Security in order to have increased lifetime monthly benefits. To address concerns that house price changes are correlated with unobserved local demand shocks, we use a control function approach and employ two different instrumental variables. We find that individuals delay Social Security claiming when house prices increase during the housing boom. The probability of claiming within two years after …

The Grid Bootstrap For Continuous Time Models, Yiu Lim Lui, Weilin Xiao, Jun Yu Apr 2022

The Grid Bootstrap For Continuous Time Models, Yiu Lim Lui, Weilin Xiao, Jun Yu

Research Collection School Of Economics

This article proposes the new grid bootstrap to construct confidence intervals (CI) for the persistence parameter in a class of continuous-time models. It is different from the standard grid bootstrap of Hansen in dealing with the initial condition. The asymptotic validity of the CI is discussed under the in-fill scheme. The modified grid bootstrap leads to uniform inferences on the persistence parameter. Its improvement over in-fill asymptotics is achieved by expanding the coefficient-based statistic around its in-fill asymptotic distribution that is non-pivotal and depends on the initial condition. Monte Carlo studies show that the modified grid bootstrap performs better than …

The Effects Of The Affordable Care Act Dependent Coverage Mandate On Parents’ Labor Market Outcomes, Kim, Koh Kanghyock Apr 2022

The Effects Of The Affordable Care Act Dependent Coverage Mandate On Parents’ Labor Market Outcomes, Kim, Koh Kanghyock

Research Collection School Of Economics

We examine the labor market impacts of the Affordable Care Act dependent mandate (ACA-DM), which has significantly increased dependent children's health insurance coverage through parents’ employer-sponsored health benefits. Using data from the American Community Survey, we find that the ACA-DM reduced parents’ annual wages by about $2,600. However, the probability of employment and working hours only decreased marginally. The back-of-the-envelope calculation indicates that the magnitude of the estimated wage impact is similar to the increased insurance premium of a family plan due to the ACA-DM. These findings imply that a deadweight loss associated with the expansion of dependent health coverage …

The Gatt/Wto Welfare Effects: 1950–2015, Pao-Li Chang, Wei Jin, Kefang Yao Apr 2022

The Gatt/Wto Welfare Effects: 1950–2015, Pao-Li Chang, Wei Jin, Kefang Yao

Research Collection School Of Economics

This paper evaluates the welfare effects of GATT/WTO-induced reductions in tariffs, vari-able and fixed trade costs, based on identified direct effects of membership indicators on trade flows via nonparametric matching estimations. The identification does not require the use of tariff data, which permits a comprehensive evaluation of the welfare impact of GATT/WTO for a long panel since its inception (1950–2015) of as many as 180 economies. The results indicate substantial (but highly dispersed) welfare gains across members of different development stages and increasing welfare losses of nonmembers in later decades by staying outside the system. An extensive set of robustness …

Shieldfl: Mitigating Model Poisoning Attacks In Privacy-Preserving Federated Learning, Zhuoran Ma, Jianfeng Ma, Yinbin Miao, Yingjiu Li, Robert H. Deng Apr 2022

Shieldfl: Mitigating Model Poisoning Attacks In Privacy-Preserving Federated Learning, Zhuoran Ma, Jianfeng Ma, Yinbin Miao, Yingjiu Li, Robert H. Deng

Research Collection School Of Computing and Information Systems

Privacy-Preserving Federated Learning (PPFL) is an emerging secure distributed learning paradigm that aggregates user-trained local gradients into a federated model through a cryptographic protocol. Unfortunately, PPFL is vulnerable to model poisoning attacks launched by a Byzantine adversary, who crafts malicious local gradients to harm the accuracy of the federated model. To resist model poisoning attacks, existing defense strategies focus on identifying suspicious local gradients over plaintexts. However, the Byzantine adversary submits encrypted poisonous gradients to circumvent existing defense strategies in PPFL, resulting in encrypted model poisoning. To address the issue, in this paper we design a privacy-preserving defense strategy using …

Computableviz: Mathematical Operators As A Formalism For Visualization Processing And Analysis, Aoyu Wu, Wai Tong, Haotian Li, Dominik Moritz, Yong Wang, Huamin. Qu

Research Collection School Of Computing and Information Systems

Data visualizations are created and shared on the web at an unprecedented speed, raising new needs and questions for processing and analyzing visualizations after they have been generated and digitized. However, existing formalisms focus on operating on a single visualization instead of multiple visualizations, making it challenging to perform analysis tasks such as sorting and clustering visualizations. Through a systematic analysis of previous work, we abstract visualization-related tasks into mathematical operators such as union and propose a design space of visualization operations. We realize the design by developing ComputableViz, a library that supports operations on multiple visualization specifications. To demonstrate …

Surveying Structural Complexity In Quantum Many-Body Systems, Whei Yeap Suen, Thomas J. Elliott, Jayne Thompson, Andrew J. P. Garner, John R. Mahoney, Vlatko Vedral, Mile Gu

Research Collection School Of Computing and Information Systems

Quantum many-body systems exhibit a rich and diverse range of exotic behaviours, owing to their underlying non-classical structure. These systems present a deep structure beyond those that can be captured by measures of correlation and entanglement alone. Using tools from complexity science, we characterise such structure. We investigate the structural complexities that can be found within the patterns that manifest from the observational data of these systems. In particular, using two prototypical quantum many-body systems as test cases-the one-dimensional quantum Ising and Bose-Hubbard models-we explore how different information-theoretic measures of complexity are able to identify different features of such patterns. …

Research Collection School Of Computing and Information Systems

Anomaly detection offers a powerful approach to identifying unusual activities and uncommon behaviors in real-world video scenes. At present, convolutional neural networks (CNN) have been widely used to tackle anomalous events detection, which mainly rely on its stronger ability of feature representation than traditional hand-crafted features. However, massive video data and high cost of CNN model training are a challenge to achieve satisfactory detection results for resource-limited users. In this paper, we propose a secure video anomaly detection framework (SecureAD) based on CNN. Specifically, we introduce additive secret sharing to design several calculation protocols for achieving safe CNN training and …

Learning For Amalgamation: A Multi-Source Transfer Learning Framework For Sentiment Classification, Cuong V. Nguyen, Khiem H. Le, Hong Quang Pham, Quang H. Pham, Binh T. Nguyen

Research Collection School Of Computing and Information Systems

Transfer learning plays an essential role in Deep Learning, which can remarkably improve the performance of the target domain, whose training data is not sufficient. Our work explores beyond the common practice of transfer learning with a single pre-trained model. We focus on the task of Vietnamese sentiment classification and propose LIFA, a framework to learn a unified embedding from several pre-trained models. We further propose two more LIFA variants that encourage the pre-trained models to either cooperate or compete with one another. Studying these variants sheds light on the success of LIFA by showing that sharing knowledge among the …

User Satisfaction Estimation With Sequential Dialogue Act Modeling In Goal-Oriented Conversational Systems, Yang Deng, Wenxuan Zhang, Wai Lam, Hong Cheng, Helen Meng Apr 2022

User Satisfaction Estimation With Sequential Dialogue Act Modeling In Goal-Oriented Conversational Systems, Yang Deng, Wenxuan Zhang, Wai Lam, Hong Cheng, Helen Meng

Research Collection School Of Computing and Information Systems

User Satisfaction Estimation (USE) is an important yet challenging task in goal-oriented conversational systems. Whether the user is satisfied with the system largely depends on the fulfillment of the user’s needs, which can be implicitly reflected by users’ dialogue acts. However, existing studies often neglect the sequential transitions of dialogue act or rely heavily on annotated dialogue act labels when utilizing dialogue acts to facilitate USE. In this paper, we propose a novel framework, namely USDA, to incorporate the sequential dynamics of dialogue acts for predicting user satisfaction, by jointly learning User Satisfaction Estimation and Dialogue Act Recognition tasks. In …

A Framework For Understanding The Taxation Of Digital Tokens, Vincent Ooi Apr 2022

A Framework For Understanding The Taxation Of Digital Tokens, Vincent Ooi

Research Collection Yong Pung How School Of Law

As a relatively new area, the taxation of digital tokens can give rise to several dangerous misconceptions. This article lays out five propositions to counter these misconceptions: 1) digital tokens are not a single monolithic asset class attracting uniform tax treatment; 2) the common trichotomous division of digital tokens into payment, utility and security tokens is derived from securities regulation and should not be blindly adopted into tax law; 3) the three classes are not mutually exclusive and hybrid tokens may exist; 4) the fact that an asset is a digital token rarely changes its tax treatment by itself, which …

Hearing, Darius Chan, Gerome Goh Apr 2022

Hearing, Darius Chan, Gerome Goh

Research Collection Yong Pung How School Of Law

In certain international commercial arbitrations, for instance, in expedited proceedings under the auspices of various institutional rules, the tribunal may decide the dispute based on documentary evidence only. However, in most cases, hearings are generally conducted for the tribunal to hear examination of any factual or expert witness and/or for oral argument. It is not uncommon for there to be multiple hearings in a single arbitration, with each hearing focusing on specific procedural or substantive issues. The hearing is therefore a forum for the parties to adduce evidence and/or put forward their legal views in direct confrontation with each other. …

Immunomodulatory Effects And Clinical Benefits Of Intravenous Immunoglobulin In Myasthenia Gravis., Marinos C Dalakas, Andreas Meisel

Department of Neurology Faculty Papers

Introduction Myasthenia gravis (MG) is an antibody-mediated disease that develops in the majority of patients mainly as a result of acetylcholine receptor (AChR) autoantibodies. This process is mediated by a series of immunoregulatory events. Therapeutic targets for MG include suppression of circulating antibodies or antibody production, suppression of complement activation, and immunomodulation of cytokines or T cells. Intravenous immunoglobulin (IVIg) has an effect on all of these mechanisms. Areas covered This narrative review explores the broad immunomodulatory effects of IVIg in MG and provides an update on IVIg treatment for MG. Expert opinion IVIg has a range of immunomodulatory effects …
