Estimating Dynamic Discrete Choice Models Of Product Differentiation: An Application To Medicare Part D With Switching Costs, Daniel P. Miller, Jungwon Yeo

Research Collection School Of Economics

This paper proposes an algorithm to estimate dynamic discrete choice models using aggregate market share data. The algorithm achieves a computational advantage by decomposing the complicated mapping between market shares and utility flows into two simpler ones. The first maps observed market shares to mean choice specific values, and the second then maps to mean utility flows. In the application, we estimate switching costs in the Medicare Part D market. Our results indicate a large switching cost of around $1,700, which implies an average welfare loss of $480 as enrollees choose to remain in sub-optimal plans to avoid switching costs.

International Activity And Domestic Law, Adam I. Muchmore

Faculty Scholarship

This invited essay explores the ways States use their domestic laws to regulate activities that cross national borders. Domestic-law enforcement decisions play an underappreciated role in the development of international regulatory policy, particularly in situations where the enforcing State's power to apply its law extraterritorially is not contested. Collective action problems suggest there will be an undersupply of enforcement decisions that promote global welfare and an oversupply of enforcement decisions that promote national welfare. These collective action problems may be mitigated in part by government networks and other forms of regulatory cooperation.

This study is based on interviews with White students graduating from a student affairs preparation program as well as a literature review of whiteness in education. Applying critical race theory, the author examined the ways that students and institutions protected whiteness. Institutions and those within them concerned with equity must have awareness of whiteness and rework curriculum, pedagogy, polices, and practices to fracture educational hegemony of whiteness.

The goal of this study was to examine the ways that White students enrolled in a student affairs master’s program in a predominantly White institution engaged with race and racism and to locate …

What Brings You Pleasure? The Role Of Desire Within The Development Of Compulsive Purchasing, Justine Rapp

College of Business: Dissertations, Theses, and Student Research

This paper seeks to put forth two major contributions into marketing scholarship: (1) the role of desire within the development of compulsivity from impulsive consumptions, and (2) an assessment of compulsivity measurement scales. A mixed method design provides for both statistical and qualitative support for both contributions, for a deeper and replicated account of consumer behavior within the marketplace. First, we develop a possible path for the development of compulsivity, explaining impulsivity as an antecedent with consumer shopping desire as the driving factor. With this, we introduce the variable Consumer Shopping Desire as a quantified construct related to Belk et …

Marketing Contracts, Overconfidence, And Timing In The Canadian Wheat Market, Fabio L. Mattos, Stefanie A. Fryza

Department of Agronomy and Horticulture: Faculty Publications

This paper investigates factors that impact marketing performance in the Canadian wheat market. Using data provided by the Canadian Wheat Board (CWB) for six crop years, results indicate that producers were not able to profitably use all marketing contracts offered by the CWB, earlier pricing tended to generate better performance, there was a negative relationship between activeness and performance (suggesting overconfidence in marketing skills), and performance was generally worse in volatile crop years. Further analysis reveals some of these findings differ when outperforming and underperforming producers are investigated separately, particularly with respect to activeness and volatility.

The Soulless Machine, Nathan Lomas

Theses

Since their creation, we have grown increasingly reliant on machines to aid us in our understanding and perceptions of the world - the camera is no exception. As an extension of the human eye, it allows us the opportunity to examine our environments from new perspectives, offering up views that we may not be able to witness on our own. Though in truth, the structure of the machine is ingrained in everything we know: from the natural world to our social patterns, actions are prescribed, parts move with united purpose, yet there is a certain comfort in the surrender of …

Supply Network Relationships: A Review Of Empirical Evidence, Andrew Humphries, Carlos Mena

Business Faculty Publications and Presentations

Supply networks are prevalent industry structures which, like the academic literature, are complex, confusing and short on practical guidance. We evaluate the current position of empirical research to expose the main constructs that can be used to study cooperative supply network relationships, to identify emergent themes, gaps and shortcomings, to share insights with managers and, to propose future research approaches. Five significant drivers of supply network relationship behaviors are identified: complexity, power, alignment of objectives, knowledge management and coordination. This paper provides a unique, topical 'map' of the supply networks field and proposes a theoretical model for integrating the many …

Clinical Review Of Treatment Options For Major Depressive Disorder In Patients With Coronary Heart Disease, Fahad D. Alosaimi, Brian Baker

Saudi Medical Journal

It is established that the prevalence of major depressive disorder (MDD) in coronary heart disease (CHD) populations is high and is associated with increased mortality. In this systematic review, we examined the evidence for the effective treatment of MDD in CHD patients by reviewing randomized control trials (RCTs) between 1980 and 2011 and then assessing whether these treatments were clinically meaningful. A total of 8 RCTs were retrieved. Sertraline, citalopram, and mirtazapine were safe from a cardiac perspective, but only sertraline and citalopram were clearly more effective than placebo in CHD patients with moderate-to-severe type, recurrent MDD, or MDD episode …

Fast And Accurate Psd Matrix Estimation By Row Reduction, Hiroshi Kuwajima, Takashi Washio, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Fast and accurate estimation of missing relations, e.g., similarity, distance and kernel, among objects is now one of the most important techniques required by major data mining tasks, because the missing information of the relations is needed in many applications such as economics, psychology, and social network communities. Though some approaches have been proposed in the last several years, the practical balance between their required computation amount and obtained accuracy are insufficient for some class of the relation estimation. The objective of this paper is to formalize a problem to quickly and efficiently estimate missing relations among objects from the …

A Multi-Site Case Study Investigating Teacher Perspectives Of Standards Based Reform And Gifted Students, Amy Valadez

Doctoral Dissertations and Projects

The push by the Federal government to directly increase and positively impact achievement since the implementation of No Child Left Behind (NCLB) (2001) gave rise to the educational design known as standards based reform (SBR). This legislation impacted all sub-groups by measuring growth for sub-populations to determine yearly adequate progress. The growth of the sub-population of gifted students, however, was not included in the determination of a school's or county's success, so the impact of standards based reform on the gifted student is lacking. Therefore, this case study examined educators' perspectives of standards based reform on the gifted child in …
