Essays On The Economics Of Immigration, Phuong Vu

Electronic Thesis and Dissertation Repository

My dissertation consists of three papers studying the impact of social networks and employment mobility on Canadian immigrants, and the effects of economic conditions and immigration policy changes on international Ph.D. students in Canada. In the first paper, I use the Longitudinal Survey of Immigrants to Canada (LSIC) to examine the effects of social networks on labour market outcomes of newly arrived Canadian immigrants. I find that the presence of initial networks at landing significantly increases the probability of getting a network job and reduces the probability of getting a formal job after landing. Across immigration categories, network effects vary, …

Essays On Macroeconomics, Mauricio Torres Ferro

Electronic Thesis and Dissertation Repository

My dissertation consists of three essays on Macroeconomics. In the first two chapters, I study the implications of uncertain expenses for households' savings and for their consumption adjustment in response to monetary policy. In the third chapter, I study how asset liquidity affects households’ ability to smooth idiosyncratic income shocks.

In the first chapter, I characterize uncertain expenses using U.S. Consumer Expenditure Survey data. Here, my goals are twofold. First, I classify households’ spending that captures uncertainties in expenses (for example, car and home repairs or out-of-pocket medical expenses) and measure their overall importance. Second, I aim to understand how …

Examining Mobile Health App Engagement In A North American Employee Population: A One-Year Longitudinal Observational Study, Nabil Ratanshi

Electronic Thesis and Dissertation Repository

BACKGROUND: Mobile health (mHealth) apps may help promote physical activity and other health behaviours among office-based workers. Low app engagement, however, leading to little or no effect is typical. OBJECTIVE: To examine engagement with a rewards-based mHealth app and identify factors influencing engagement. METHODS: A one-year observational study was conducted with Canadian and U.S. users of the Sprout at Work app (N=2253; Female: 35.7%; Age: 39.3 years). Kaplan-Meier survival curves were used to examine engagement patterns from a ‘multiple-lives’ perspective (i.e., time to first disengagement, re-engagement, second disengagement). Regression models were used to identify factors influencing engagement. RESULTS: After one …

Essays On Financial Shocks And External Debt, Jafar El Armali

Electronic Thesis and Dissertation Repository

My thesis consists of three chapters: two chapters on the effects of financial shocks, and one on the relationship between external debt and economic growth in low- and middle-income countries.

Chapter 1, “Financial Shocks, Interbank Rates and Corporate Rates”, introduces financial shocks that change interbank and corporate debt rates and their spread and shows how these shocks affect economic fluctuations.

Chapter 2, “Tighter Debt Limits, Default, and Labour Supply”, shows that the effect of tighter debt limits on households' labour supply decisions depends on whether default is allowed or not.

Chapter 3, “External Debt, Initial Conditions, and Economic Growth in …

Statistical Roles Of The G-Expectation Framework In Model Uncertainty: The Semi-G-Structure As A Stepping Stone, Yifan Li

Electronic Thesis and Dissertation Repository

The G-expectation framework is a generalization of the classical probability system based on the sublinear expectation to deal with phenomena that cannot be described by a single probabilistic model. These phenomena are closely related to the long-existing concern about model uncertainty in statistics. However, the distributions and independence in the G-framework are quite different from the classical setup. These distinctions bring difficulty when applying the idea of this framework to general statistical practice. Therefore, a fundamental and unavoidable problem is how to better understand G-version concepts from a statistical perspective.

To explore this problem, this thesis establishes a new substructure …

Essays On The Economics Of Education, Enrique Martin Luccioni

Electronic Thesis and Dissertation Repository

My thesis consists of three chapters on the Economics of Education. In the first chapter, I take a structural approach to studying the extent to which teacher behavior and teacher interactions with students determine teaching contribution to test score growth in the classroom. Teachers’ contributions may differ across classrooms, as it may depend on the types of students taught and because teachers may adjust their effort to new contexts. The estimated model suggests that teacher and student efforts play a significant role in determining student knowledge. My findings indicate that teachers who are effective in teaching low-performing students may not …

Essays On Disability And The Labour Market, Robert Geoffrey Millard

Electronic Thesis and Dissertation Repository

My dissertation consists of three chapters about the effects of disability and disability policy.

The second chapter analyzes the variation in labour market outcomes across disabilities by representing disability as a bundle of characteristics. Rich with information on the characteristics of a disabling condition, I use the Participation and Activity Limitation Survey to compare the relative importance of each {characteristic} and their interactions on employment, wages, hours worked, and annual employment income. The disability {characteristics} include the type of activity limitation, number of limitations, timing of onset, severity, and persistence. I find substantial cross-sectional variation in labour supply, wages, and …

Community Development Agreements: The Hardening And Evaluation Of A Norm, Luka G. Petrusevski

Electronic Thesis and Dissertation Repository

Large scale mining projects generate highly variable outcomes. Proponents of mining cite benefits including job creation and revenue generation, while critics point to adverse social and economic impacts borne by mining-proximate communities. Community-based concerns about mining operations have raised ethical and social justice considerations relating to human-rights and consent. Community development agreements (CDAs) have emerged as an increasingly common tool to address such concerns and facilitate the delivery of tangible benefits from mining operations to affected communities. The effectiveness of CDAs, however, varies widely depending on the negotiated provisions and their implementation. This work contributes to the understanding of CDAs …

Essays On Industrial Organization And Health Economics, Cecilia S. Diaz Campo

Electronic Thesis and Dissertation Repository

My thesis consists of three chapters studying the impact of health insurance design and public health policy on consumers’ health and health care utilization, welfare, and costs.

Chapter 2 studies an overlooked dynamic incentive that encourages health care utilization, which I term \textit{dynamic moral hazard}. Typical health plans feature high deductibles and caps on consumers' out-of-pocket spending, which generate nonlinear pricing. These nonlinearities, coupled with the uncertainty intrinsic to future health care demand, encourage consumers to increase spending since current utilization lowers future expected prices. Standard models study health care utilization decisions through the lens of annual models, which abstract …

Revealed Preference Analysis: Theory And Applications, Charles Gauthier

Electronic Thesis and Dissertation Repository

This dissertation consists of three chapters studying revealed preference theory and its applications to testing and inference. The first chapter develops a semiparametric revealed preference methodology to analyze the effects of price search on prices paid across income groups. The second chapter derives a novel representation of the exponential discounting model to make inference on the discount factor. The third chapter derives an axiomatization of the exponential discounting model and uses it to propose a nonparametric test of dynamic discrete random utility models.

The first chapter develops a novel semiparametric approach to estimate the impacts of price search on prices …

Essays On Conflict Mediation, Ali Kamranzadeh

Electronic Thesis and Dissertation Repository

An important barrier to conflict resolution is asymmetric information. That is adversaries have private information about their objectives, resources, and strengths during the conflict and have incentives to misrepresent this information during the negotiations. Third-party institutions, like mediators, can help adversaries to reach an agreement by making a peace proposal. In this thesis, I explore the implication of asymmetric information of players to the design of an optimal peace proposal by a mediator.

Chapter 2, co-authored with Charles Zheng, studies a problem of conflict mediation where a mediator proposes a split of a good between two ex-ante identical contestants thereby …

Essays On The All-Pay Auction, Henk Schouten

Electronic Thesis and Dissertation Repository

Three all-pay auction models are examined. The first is a symmetric two-player binary-signal all-pay auction with correlated signals and interdependent valuations. The first chapter provides a complete characterization of each form of equilibrium and gives conditions for their existence. The main finding is that there generically exists a unique equilibrium. The unique equilibrium can only be one of four forms of equilibria. I apply my all-pay auction model to elections, where a candidate that receives good news from the polls behaves in a rationally overconfident manner and reduces her equilibrium effort. Consequently, the other candidate can win the election in …

Essays On Market Design And Auctions, Mingshi Kang

Electronic Thesis and Dissertation Repository

My thesis consists of three chapters that contribute to redistribution-driven market design and sponsored link auctions.

Chapter 2 and 3 (co-authored with Charles Zheng) study redistribution-driven market design with endogenous buyers and sellers. In Chapter 2, we consider a large market environment with each individual endowed with equal shares of a limited resources and allowed to buy or sell the shares. We characterize the interim (incentive-constrained) Pareto frontier subject to market clearance and budget balance, and find that at most two prices are needed to attain any (interim) Pareto optimum. Under robust conditions of the primitives, the Pareto optimal allocation …

Application Of A Polynomial Affine Method In Dynamic Portfolio Choice, Yichen Zhu

Electronic Thesis and Dissertation Repository

This thesis develops numerical approaches to attain optimal multi-period portfolio strategies in the context of advanced stochastic models within expected utility and mean-variance theories. Unlike common buy-and-hold portfolio strategies, dynamic asset allocation reflects the investment philosophy of a portfolio manager that benefits from the most recent market conditions to rebalance the portfolio accordingly. This enables managers to capture fleeting opportunities in the markets thereby enhancing the portfolio performance. However, the solvability of the dynamic asset allocation problem is often non-analytical, especially when considering a high-dimensional portfolio with advanced models mimicking practical asset's return. To overcome this issue, this thesis presents …

Cost-Effectiveness Analysis Of Tpmt Genotype-Guided Azathioprine Treatment Compared To Standard Treatment For Patients With Moderate/Severe Ulcerative Colitis, Ali Unsal

Electronic Thesis and Dissertation Repository

This study assessed cost-effectiveness of pharmacogenomics (PGx)-based azathioprine (AZA) compared to standard AZA therapy for ulcerative colitis (UC) patients in Canada. A patient-level Microsimulation model was developed to compare the lifetime costs and quality-adjusted life years (QALYs) gained by a hypothetical cohort of UC patients with age and sex characteristics. The parameters used in the model were derived from the published literature and costs from the Ontario Schedules of Payments and published sources. The results were summarized in terms of the incremental cost-effectiveness ratio (ICER). Compared to standard AZA, PGx-based AZA care was the dominant strategy with 0.17 incremental QALYs …

Essays In Financial Asset Pricing, Dillon Ross Huddleston

Electronic Thesis and Dissertation Repository

Three essays in financial asset pricing are given; one concerning the partial differential equation (PDE) pricing and hedging of a class of continuous/generalized power mean Asian options, via their (optimal) Lie point symmetry groups, leading to practical pricing formulas. The second presents high-frequency predictions of S&P 500 returns via several machine learning models, statistically significantly demonstrating short-horizon market predictability and economically significantly profitable (beyond transaction costs) trading strategies. The third compares profitability between these [(mean) ensemble] strategies and Asian option Δ-hedging, using results of the first. Interpreting bounds on arithmetic Asian option prices as ask and bid values, hedging profitability …

Essays On Firms In International Trade, Aldo Sandoval Hernandez

Electronic Thesis and Dissertation Repository

My thesis is composed by three chapters that study the important role that firms play in mediating imports and exports between countries, and how their decisions and heterogeneity can influence the behavior of macroeconomic outcomes. The first chapter, explores the role of demand uncertainty and learning in explaining the low survival rates and sales of new exporters using a manufacturing survey for Colombian firms. In the second chapter, using a transaction-level dataset for Colombian exporters, I document novel facts about the post-entry dynamics of firm performance and prices in international markets, and study their connection with the transmission of exchange …

On The Estimation Of Heston-Nandi Garch Using Returns And/Or Options: A Simulation-Based Approach, Xize Ye

Electronic Thesis and Dissertation Repository

In this thesis, the Heston-Nandi GARCH(1,1) (henceforth, HN-GARCH) option pricing model is fitted via 4 maximum likelihood-based estimation and calibration approaches using simulated returns and/or options. The purpose is to examine the benefits of the joint estimation using both returns and options over the fundamental returns-only estimation on GARCH models. From our empirical studies, with the additional option sample, we can improve the efficiency of the estimates for HN-GARCH parameters. Nonetheless, the improvements for the risk premium factor, both from empirical standard errors, and sample RMSEs, are insignificant. In addition, option prices are simulated with a pre-defined noise structure and …

Analysis Of Health Care Costs Over A One-Year Period Following Anticoagulant Therapy Among Ontario Patients Diagnosed With Atrial Fibrillation, Michael Situ

Electronic Thesis and Dissertation Repository

Atrial fibrillation patients are at high risk of ischemic strokes, which can be drastically reduced using oral anticoagulants (OACs). Warfarin has been the standard OAC for this population but its effectiveness rests on consistent monitoring with the potential for severe bleeding events. Newer OACs, like rivaroxaban and apixaban, address these drawbacks but have a comparatively higher upfront cost. Uncertainty remains over which OAC is cost-saving from a health care system perspective. Using a retrospective cohort study design and inverse probability weighting regression adjustment estimators, one-year health care costs among patients treated with warfarin, rivaroxaban, and apixaban were compared. Compared to …

Essays In Financial Econometrics And Machine Learning, Fred Liu

Electronic Thesis and Dissertation Repository

Financial econometrics is a highly interdisciplinary field that integrates finance, economics, probability, statistics, and applied mathematics. Machine learning is a growing area in finance that is particularly suitable for studying problems with many variables. My thesis contains three chapters that explore financial econometrics and machine learning in the fields of asset pricing and risk management.

Chapter 2 studies the implications of the new Basel 3 regulations. In 2019, the BCBS finalized the Basel 3 regulatory regime, which changes the regulatory measure of market risk and adds new complex calculations based on liquidity and risk factors. This chapter is motivated by …

Essays On Private Information And Monetary Policy, Zijian Wang

Electronic Thesis and Dissertation Repository

In our economy, many interactions between individuals involve one party possessing more or better information than the other party (i.e., private information). For example, in asset markets, sellers often have better knowledge about the quality of the assets than buyers. Private information also exists when governments collect taxes, because taxpayers typically have more information about their income compared to the government. In my thesis, I explore the implications of private information in three novel contexts.

In Chapter 2, I study the implications of tax evasion for the design of central bank digital currency, which is an emerging payment instrument. I …

Three Essays On Individual And Household Responses To Information, Liquidity, And Policy Shocks, Brian C. Held

Electronic Thesis and Dissertation Repository

This thesis consists of three empirical studies of heterogeneous individual and household behaviour in response to shocks that occur in the labour market and in the consumer marketplace. Chapter 2 contributes to the labour literature by examining the long-term effects of firings on subsequent labour market outcomes from an ability learning perspective. Chapter 3 contributes to the household savings and personal finance literature by studying how households navigate temporary liquidity shocks due to income disruption. Chapter 4 contributes to our understanding of online sales tax policy in the context of the rural-urban divide. In Chapter 2, I develop a search …

Heavy Metal Fundraisers: Entrepreneurial Recording Artists In Platform Capitalism, Jason Netherton

Electronic Thesis and Dissertation Repository

Abstract

How do cultural producers square customary understandings of what it means to be authentic and autonomous creators in new contexts characterized by digital-era entrepreneurial pressures and online platform-mediated financial opportunities? This study examines how heavy metal recording artists experience these pressures; how some of them engage in platform-based crowdfunding, argue over its legitimacy, and rationalize varying degrees of acceptance and dependence. First, my analysis centers on a case study which follows the experiences of a progressive metal band as they navigate a new financial relation in conjunction first with the fundraising platform Pozible and then the patronage-based crowdfunding platform …

Examination Of Institutional Investment In The United States Of America From 1999 To 2018, Martin R. Lefebvre

Electronic Thesis and Dissertation Repository

This thesis examines the evolution of spatial preference of institutional investors located in the United States of America for the time period of 1999 to 2018 using a mix of exploratory data analysis techniques and more sophisticated space-time and machine learning techniques such as ESRI Space-Time cube and Latent Dirichlet Allocation topic modeling. This thesis concludes that despite having the appearance of a footloose industry due to almost negligible fixed costs, institutional investors are attracted to highly dynamic urban centres and on the 20 year time horizon, appear surprisingly sticky in their location preference. This is consistent with the belief …

Adding Data-Driven Modelling To Causal Inference And Financial Economics, Sha Wang

Electronic Thesis and Dissertation Repository

My thesis, which consists of three chapters, aims to either adapt ML to solve important questions in financial markets, or apply state-of-the art ML methodologies that specifically target on economic causal inference problems. The first chapter is adapted from a paper co-authored with Lars Stentoft and published on the Journal of Portfolio Management in 2019. We modified a ML model in order to develop a portfolio tracking strategy that solves a pain point for investors. Many investors try to replicate the performance of certain financial instrument, such as a hedge fund strategy return index for its desirable risk-return profile. However, …

Essays On Student Loans And Returns To Skill, Qian Liu

Electronic Thesis and Dissertation Repository

This thesis consists of three studies, which explore topics related to labor economics. Chapters 2 and 3 examine the returns on student loans and student loan repayment policy, respectively. Chapter 4 examines the returns to skill and the evolution of skills at older ages.

In Chapter 2 (co-authored with Lance Lochner), we study rates of return on government student loans in Canada using novel administrative data from the Canada Student Loans Program. We exploit rich information on personal characteristics, loan amounts, field of study, and institution of attendance to explain differences in rates of return across different types of borrowers. …

Essays On Share Repurchases And Boom-Bust Cycles, Bohan Li

Electronic Thesis and Dissertation Repository

My doctoral dissertation consists of three chapters on financial economics. In the first chapter, I examine whether a firm's share repurchases and issuances reveal information on its future 2-year stock returns. Firm-quarter observations with repurchases or issuances are each divided into twenty 5-percentile bins sorted by their magnitude. I regress 2-year future stock returns on the bins and find a non-linear relationship between the change in shares outstanding and returns. Firms making repurchases (issuances) of less than 9.3% (1.4%) of shares outstanding outperform the equal-weight portfolio by 6.4% (3.9%). These observations account for 90% of repurchases and 70% of issuances. …

Understanding The Determinants Of The Cost Of Coronary Artery Bypass Graft Surgery, Hun Lee

Electronic Thesis and Dissertation Repository

Introduction: The relationship between patient demographics, clinical factors, and cost of coronary artery bypass graft (CABG) is complex. Investigation of these relationships is important to aid clinical practice and inform reimbursement models. This thesis analyzes multiple different domains in order to understand the significant factors that impact the cost of CABG at the London Health Sciences Centre (LHSC).

Methods: Model selection, construction of nested descriptive models, exploration of mediation analysis of the impact of peri-operative factors and cost through length of stay, and construction of estimative models were performed.

Results: Several baseline characteristics, socio-demographics, peri-operative variables, and post-operative variables were …

The Impact Of Levodopa Administration On Learning From Short-Term And Long-Term Action Consequences: A Paradigm Validation., Masood Rezaei

Electronic Thesis and Dissertation Repository

Behavioral and neuroimaging studies have identified two valuation systems in the human brain for controlling behavior known as model-free (MF) and model-based (MB). MF is based on immediate evaluation and MB is based on long-term evaluation of the outcome of our decisions. Previous studies suggest that dopamine baseline activity may play an important role in the balance between the two systems and determine how they compete or interact in controlling our actions. The overarching aims of this study is to investigate the impact of levodopa administration on learning from immediate and long-term action consequences, and to dissociate the role of …

A Language Barrier To Human Capital Development: The Case Of Guatemalan Students, Fidel Pérez Macal

Electronic Thesis and Dissertation Repository

Not being proficient in a school’s predominant language of instruction can represent a language barrier for students’ human capital development. In Guatemala, 24 languages are spoken apart from Spanish, which is the language of instruction in the majority of schools, and about 40 percent of the total population has a non-Spanish language as a mother tongue. National standardized tests show that non-Spanish mother tongue (non-SMT) students are outperformed by SMT students in elementary and secondary schools.

My thesis analyzes whether non-SMT students face a language barrier and traces its source. Two main findings emerge. First, non-SMT students are not yet …
