Three Essays On Financial Economics, Jiangyuan Li

Dissertations and Theses Collection (Open Access)

Disagreement measures are known to predict cross-sectional stock returns but fail to predict market returns. This paper proposes a partial least squares disagreement index by aggregating information across individual disagreement measures and shows that this index significantly predicts market returns both in- and out-ofsample. Consistent with the theory in Atmaz and Basak (2018), the disagreement index asymmetrically predicts market returns with greater power in high sentiment periods, is positively associated with investor expectations of market returns, predicts market returns through a cash flow channel, and can explain the positive volume-volatility relationship.

Essays On Heterogeneous Large Panel Data Models, Ke Miao

Dissertations and Theses Collection (Open Access)

This dissertation consists of three papers which contribute to the estimation and inference theory of the heterogeneous large panel data models. The first chapter studies a panel threshold model with interactive fixed effects. The least-squares estimators in the shrinking-threshold-effect framework are explored. The inference theory on both slope coefficients and the threshold parameter is derived, and a test for the presence of the threshold effect is proposed. The second chapter considers the least-squares estimation of a panel structure threshold regression (PSTR) model, where parameters may exhibit latent group structures. Under some regularity conditions, the latent group structure can be correctly …

Essays On Agricultural Commodity Processing, Bin Li

Dissertations and Theses Collection (Open Access)

This dissertation investigates two important issues in agricultural commodity processing: (i) biomass commercialization; that is, converting organic waste into a saleable product, from economic and environmental perspectives, and (ii) optimal procurement portfolio design using multiple suppliers and spot market, and the impact of by-product introduction on this optimal portfolio.

The first chapter examines the economic implications of biomass commercialization from the perspective of an agri-processor that uses a commodity input to produce both a commodity output and biomass. We characterize the value of biomass commercialization and perform sensitivity analysis to investigate how spot price uncertainty (input and output spot price …

Detecting Latent Communities In Network Formation Models, Shujie Ma, Liangjun Su, Yichong Zhang

Research Collection School Of Economics

This paper proposes a logistic undirected network formation model which allows for assortative matching on observed individual characteristics and the presence of edge-wise fixed effects. We model the coefficients of observed characteristics to have a latent community structure and the edge-wise fixed effects to be of low rank. We propose a multi-step estimation procedure involving nuclear norm regularization, sample splitting, iterative logistic regression and spectral clustering to detect the latent communities. We show that the latent communities can be exactly recovered when the expected degree of the network is of order log n or higher, where n is the number …

Forecast Combinations In Machine Learning, Yue Qiu, Tian Xie, Jun Yu

Research Collection School Of Economics

This paper introduces novel methods to combine forecasts made by machine learning techniques. Machine learning methods have found many successful applications in predicting the response variable. However, they ignore model uncertainty when the relationship between the response variable and the predictors is nonlinear. To further improve the forecasting performance, we propose a general framework to combine multiple forecasts from machine learning techniques. Simulation studies show that the proposed machine-learning-based forecast combinations work well. In empirical applications to forecast key macroeconomic and financial variables, we find that the proposed methods can produce more accurate forecasts than individual machine learning techniques and …

Asymptotic Theory For Near Integrated Processes Driven By Tempered Linear Processes, Farzad Sabzikar, Qiying Wang, Peter C. B. Phillips

Research Collection School Of Economics

In an early article on near-unit root autoregression, Ahtola and Tiao (1984) studied the behavior of the score function in a stationary first order autoregression driven by independent Gaussian innovations as the autoregressive coefficient approached unity from below. The present paper develops asymptotic theory for near-integrated random processes and associated regressions including the score function in more general settings where the errors are tempered linear processes. Tempered processes are stationary time series that have a semi-long memory property in the sense that the autocovariogram of the process resembles that of a long memory model for moderate lags but eventually diminishes …

Econometric Methods And Data Science Techniques: A Review Of Two Strands Of Literature And An Introduction To Hybrid Methods, Tian Xie, Jun Yu, Tao Zeng

Research Collection School Of Economics

The data market has been growing at an exceptional pace. Consequently, more sophisticated strategies to conduct economic forecasts have been introduced with machine learning techniques. Does machine learning pose a threat to conventional econometric methods in terms of forecasting? Moreover, does machine learning present great opportunities to cross-fertilize the field of econometric forecasting? In this report, we develop a pedagogical framework that identifies complementarity and bridges between the two strands of literature. Existing econometric methods and machine learning techniques for economic forecasting are reviewed and compared. The advantages and disadvantages of these two classes of methods are discussed. A class …

Examining The History Of Racial Groups To Understand Health Disparities In Monterey County, Virginia Murillo

Capstone Projects and Master's Theses

The Monterey County Health Department’s Health Equity Scholars Academy aspires to train health workforce leaders to prioritize equity into services. Health inequities occur when there are systematic differences in the health statuses of different populations. These disparities perpetuate negative health outcomes for minority groups. In Monterey County, too few public employees are aware of the types and pervasiveness of health inequities experienced by a significant proportion of the population. A timeline was developed to provide a more accessible way to educate public employees about significant events and policies affecting Monterey County resident’s health. Content from the timeline has been incorporated …

Safe Ag Safe Schools (SASS) is a local pesticide reform organization with members at the state and local levels aiming towards sustainable agricultural practices. SASS focuses on serving agriculturally working families and community members who reside near agricultural areas. The problem addressed by the capstone is that too many marginalized, low-income communities are facing environmental injustices produced by large corporation’s methods of generating revenue. These injustices include high risk of pesticide exposure due to inadequate training and access to equipment. The project focused on assessing farm workers’ knowledge regarding pesticide safety and decontamination procedures. The Office of the Monterey Agricultural …

Importance Of Mental Health Awareness In Schools, Alexandra Elliott

Capstone Projects and Master's Theses

We all have different experiences and beliefs that shape our perspectives and impact our mental health. The concept of mental health exists in Western civilization but is absent in others, so it is important to be sensitive when discussing the terminology of mental health by itself. There is ample evidence of a disproportionate amount of mental health issues among people living in low-income areas due to lack of resources in these communities. In fact, mental health resources are disproportionately accessible to white, affluent individuals in Western civilization. This senior capstone research project is intended to find ways to reach new …

What Kind Of Resources Are There For Caregivers Of Patients With Mental Illness?, Candice Robertson

Capstone Projects and Master's Theses

The capstone was implemented at Telecare, an agency that serves individuals who are on a psychiatric hold. The capstone’s macro-level problem is that caregivers are not receiving the support they need to adequately help their patients. The micro-level was that my agency works with the family so the social workers should be giving out appropriate resources for the caregivers. The capstone consisted of conducting research to assess the different resources that were available for caregivers online. I implemented this by conducting systematic GOOGLE searches and organizing top results by common themes that were in the articles found in the top …

“So, Literally,…Basically,...It’S Like…”: A Study Into The Generational And Sociological Impact Of American Language Culture, Richard Moreno

Capstone Projects and Master's Theses

Language is unique to the human species. It serves to communicate thoughts, feelings, emotions, etc. Within the context of this capstone I outline the theory that language is much more than this. Words can also serve to bond or reject, based on the level of acceptance within social groups towards the speaker. In seeking to discover what effects specific language utterances have on social interaction and the processes involved in developing cohesiveness collective identity in these groups, I found that they do have a definite impact and this is based mainly within generational parameters. Using a mixed method approach of …

The Influence Of State Political Orientation On Firm Environmental Practices, Trisha Coberly

Honors Program Theses

The purpose of this thesis is to examine the correlation between the political environment of the state where a company is headquartered and the implementation of environmentally sustainable practices. Additionally, I add firm specific factors as moderating variables to see if they will positively or negatively influence this relationship. Although there is an abundance of research on Corporate Social Responsibility (CSR) and its effects on firm performance this paper will look more narrowly at the environmental aspect of CSR and use state political orientation as the independent variable with firm characteristics acting as the moderating variables. Our results conclude that …

Perceptions Of Dementia In Faith-Based Organizations, Megan Elizabeth Kooker

Honors Program Theses

Dementia is a public health concern. The number of people who will have some form of dementia is expected to rise in the coming years (Brookmeyer, 2011). Around 50 million people have dementia worldwide. Every year, this number increases by about 10 million (World Health Organization, 2019). Because this is such a prevalent issue, each part of the community should be educated about dementia as well as how to best interact with people living with dementia (PLWD). In order to educate these individual community sectors, it is important to first research the existing perceptions about dementia among the community. Faith …

The Complexities Of Intimacy, Brie Henderson

Graduate School of Art Theses

Through my research I have discovered there are many complexities that exist within the topic of intimacy. Of these complexities, I chose to explore the topics attachment and codependency in my final series. Attachment and codependency are deeply rooted in psychology, poetry, and many artist’s practices. The relationship between poetry and my work has become deeply intertwined. I combine poetry with my work as a way to document my feelings and to inspire the titles for my paintings. Through a series of intimate watercolor paintings, I reference bodies, intimate interactions and the ambiguity within the two. This ambiguity asks viewers …

The Art Of 'Stick To Sports,' Politics, And Sports Media Industry Studies, Shi-Quan Nettingham

UNLV Theses, Dissertations, Professional Papers, and Capstones

This thesis aims at unpacking the discourse of “stick to sports,” which audiences wield to police social and cultural boundaries and battles involving race, gender, and politics. The melding of sports and politics, primarily through social media platforms, riles up audiences resulting in arguments where larger social issues are deliberated and processed. The stick to sports discourse is used to dictate who can and can’t speak and what kinds of discussions are appropriate in relation to sports. The sports network ESPN is a site for understanding how corporations leverage this discourse and use it to claim political neutrality, while disciplining …

Zooarchaeology Of Bone, Antler, And Ivory Technologies: A Case Study From The Central Anatolian Bronze And Iron Age Site Kaman Kalehӧyük, Sarah Raffae Macintosh

UNLV Theses, Dissertations, Professional Papers, and Capstones

The proposed dissertation research investigates bone, antler, and ivory technologies in central Anatolia (present-day Turkey) during the Bronze and Iron Ages (ca. 3000-100 Before Current Era or BCE). At this time, rural agrarian societies were transforming into more complex polities and states. This transformation was marked by a rapid increase of social complexity as documented in the archaeological record in terms of monumental administrative and religious buildings, uniform ceramic ware, and writing. The current archaeological record also informs us about the rate of technological change in pottery, architecture, and metallurgy, as typology, style, and function are widely documented and studied …

Love In South Korea: Transformations Of Intimacy And Gender Relations In Korean Romantic Relationships, Alex Joseph Nelson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Romantic love holds a central place in South Korean imaginaries, animating television dramas and pop ballads, but has been largely overlooked in Korea's ethnographic record. Drawing on data collected through 18 months of ethnographic fieldwork, survey research, interviews, and analysis of folklore, the present study investigates how South Koreans conceptualize romantic love, how those conceptions have changed over time, and the ways they are transforming with the Korean field of gender relations.

This study documents love's entwinement with marriage in South Korea. Koreans are developing companionate ideals of marriage that shift the focus of kinship from the parent-child relationship to …

Excavating Gender: The Embodiment And (Re)Presentation Of Social Relations In Mierzanowice Communities Of The Early Bronze Age, Mark Paul Toussaint

UNLV Theses, Dissertations, Professional Papers, and Capstones

The construction of gender in a society is based on a discursive relationship between culture and biology. Ideological components are often translated into structural factors, which condition access to social and biological resources and exposure to risk. Cumulative differential health outcomes for groups can become embodied in ways that affect the skeleton. By conducting population-level analyses of skeletal markers of health and trauma, bioarchaeologists work backwards to attempt to reconstruct social conditions. Archaeological and mortuary context is an important part of this process.

Cemeteries of the Mierzanowice Culture (MC) in southern Poland (2300-1600 BCE) offer a unique opportunity to study …

Stress And Coping In Food-Insecure African Americans In Clark County, Nevada, Johanna Andrews

UNLV Theses, Dissertations, Professional Papers, and Capstones

African Americans have the highest rates of food insecurity than any other racial/ethnic group in the nation as a result of poverty, low household income, unemployment, food injustice, food mirages, and racial segregation. This consistent uncertainty in food access demonstrably results in poor mental health outcomes for food-insecure African Americans. Thus, the Transactional Model of Stress and Coping provides a theoretical framework to investigate how African Americans cope with food insecurity. The purpose of this study was to evaluate processes of coping with food insecurity and determine their impact on emotional well-being for African Americans in Clark County, Nevada. A …

Examining The Factor Structures Of The A-Des And Ptci To Identify Unique Predictors Of Ptsd Symptom Clusters In Maltreated Youth, Amanda Howard

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research on childhood posttraumatic stress disorder (PTSD) has increased over the past decade. Youth who experience maltreatment are more likely to exhibit symptoms of PTSD. At present, the literature largely focuses on youth who have experienced general trauma or PTSD symptoms, while maltreated youth are understudied. To date, no studies have examined the psychometric properties of the Adolescent Dissociative Experiences Scale (A-DES) or the Posttraumatic Cognitions Inventory (PTCI) in a sample of maltreated youth. Predictors of childhood PTSD for maltreated youth remain unknown. The present study was the first research study to date to examine the factor structures of the …
