Labor supply and accounting firm mergers
(Massachusetts Institute of Technology, 2020)In this paper, I study how regulation-induced accounting labor supply shocks affect the audit market. Using a novel dataset that includes both large and small accounting firms, I identify labor supply shocks using the ... -
Lack of commitment and strategic behavior : four essays in financial economics
(Massachusetts Institute of Technology, 1990) -
Lambda-calculus models of programming languages.
(Massachusetts Institute of Technology, 1969) -
A Langrangian decomposition approach to weakly coupled dynamic optimization problems and its applications
(Massachusetts Institute of Technology, 2003)We present a Lagrangian based approach to decoupling weakly coupled dynamic optimization problems for both finite and infinite horizon problems. The main contributions of this dissertation are: (i) We develop methods for ... -
Large scale queueing systems : asymptotics and insights
(Massachusetts Institute of Technology, 2011)Parallel server queues are a family of stochastic models useful in a variety of applications, including service systems and telecommunication networks. A particular application that has received considerable attention in ... -
Large-scale analytics and optimization in urban transportation : improving public transit and its integration with vehicle-sharing services
(Massachusetts Institute of Technology, 2013)Public transportation is undeniably an effective way to move a large number of people in a city. Its ineffectiveness, such as long travel times, poor coverage, and lack of direct services, however, makes it unappealing to ... -
Learning and transfer of understanding in dynamic decision environments
(Massachusetts Institute of Technology, 1994) -
Learning at the boundary of the firm : learning-by-interaction between a manufacturer and its users
(Massachusetts Institute of Technology, 2009)My dissertation centers on the very nature of the interaction and the learning that happens between users and manufacturers, and explores various micro-level mechanisms, which I call, "learning-by-interaction." The core ... -
Learning strategies and performance in organizational teams
(Massachusetts Institute of Technology, 2005)(cont.) shows that vicarious learning is positively associated with performance. I argue that vicarious team learning is an under-explored dimension of what makes teams and organizations competitive. The chapter concludes ... -
Learning with structured decision constraints
(Massachusetts Institute of Technology, 2018)This thesis addresses several prediction and estimation problems under structured decision constraints. We consider them in two parts below. Part 1 focuses on supervised learning problems with constrained output spaces. ... -
Leveraging data analytics to improve outpatient healthcare operations
(Massachusetts Institute of Technology, 2020)Healthcare reform in the United States has received significant attention from the public, physicians, health administrators, and insurance payors. The important policy discussions surrounding healthcare reform have a ... -
Liberalizing development : effects of telecommunication liberalization in Thailand and the Philippines
(Massachusetts Institute of Technology, 2001)This thesis hypothesized that extensive telecommunications liberalization would not increase the penetration rate of the fixed telephone service better than other, less competition-oriented, policy alternatives. The ... -
Limit order markets, liquidity, and price impact
(Massachusetts Institute of Technology, 2004)In this thesis, I explore various aspects of market liquidity and analyze its effect on asset prices. First, in a model of a limit order market I explain how to define liquidity and derive a price impact function. Second, ... -
Linear programming and capacitated network loading
(Massachusetts Institute of Technology, 1998) -
Local energy management through mathematical modeling and optimization
(Massachusetts Institute of Technology, 2004)(cont.) Extensions to the core TOTEM model include a demand charge model, used for making daily optimal control decisions when the electric bill includes a charge based on the monthly maximum power draw. The problem of ... -
Location problems in the presence of queueing
(Massachusetts Institute of Technology, 1982) -
Locked-in : the effect of CEOs' capital gains taxes on corporate risk-taking
(Massachusetts Institute of Technology, 2017)I study the effects of CEOs' unrealized capital gains tax liabilities (tax burdens) on corporate risk-taking. Recent work suggests that high tax burdens discourage CEOs from selling stock. I hypothesize that this causes ... -
Lowering outbound shipping costs in an online retail environment by making better fulfillment and replenishment decisions
(Massachusetts Institute of Technology, 2012)As online retailing - or e-tailing - continues to grow as more and more customers buy physical goods on the internet, finding ways to reduce the cost and environmental impact of outbound shipping in this sector will become ... -
Machine learning approaches to challenging problems : interpretable imbalanced classification, interpretable density estimation, and causal inference
(Massachusetts Institute of Technology, 2018)In this thesis, I address three challenging machine-learning problems. The first problem that we address is the imbalanced data problem. We propose two algorithms to handle highly imbalanced classification problems. The ... -
Machine learning for problems with missing and uncertain data with applications to personalized medicine
(Massachusetts Institute of Technology, 2019)When we try to apply statistical learning in real-world applications, we frequently encounter data which include missing and uncertain values. This thesis explores the problem of learning from missing and uncertain data ...
