Immigration and within-group wage inequality : how queuing, competition, and care outsourcing exacerbate and erode earnings inequalities by Eiko H Strader( )

1 edition published in 2017 in English and held by 52 WorldCat member libraries worldwide

The rhetoric against immigration in the United States mostly focuses on the economic threat to low-educated native-born men using a singular labor market competition lens. In contrast to this trend, this dissertation builds on a large body of previous work on job queuing and ethnic competition, as well as insights gained from the studies on female labor force participation and the outsourcing of care work. By exploring regional differences in the wage effects of immigration across 100 metropolitan areas between 1980 and 2007, I argue that immigration is an intersectionally dynamic localized source of wage inequality and equality. The first chapter provides an overview of the current literature concerning the wage effects of immigration on native-born workers. The second chapter asks empirically whether immigration is related to regional differences in the gender wage gap, and finds that the gap is narrower in cities with higher concentrations of migrant domestic workers. In chapter three, I focus on native-born women only and investigate how within-women inequalities are mediated, unchanged, or sustained through immigration by race, class and motherhood. In the fourth chapter, I discuss the benefits and limitations of fixed- and random-effects models, and advocate for the use of hybrid-effects models for intersectional scholars who consider social inequality to be a multidimensional experience across time and space. Ultimately, I conclude that the wage effects of immigration are the result of gendered, raced and classed queuing processes, as well as changes in household production decisions. Findings presented in this dissertation advance empirical and theoretical debates on the linkage between immigration and within-country wage inequality by arguing that the wage effects of immigration are intersectionally dynamic. The policy implications of my dissertation are twofold. First, the binary treatment of native-born workers against immigrants is misguided because immigration intersects with other sources of inequality. Secondly, the continued reliance on the market-based care, as opposed to publicly provided care, increases the labor market vulnerability of some native-born workers
Two distribution tactics for retail demand fulfillment by Milad Ebtehaj( )

1 edition published in 2013 in English and held by 20 WorldCat member libraries worldwide

In the first decade of the twenty-first century, the doubling of the global retailing from seven to fourteen trillion dollars has been accompanied by a soaring competition in the marketplace. Further, ever-rising customer expectations for the availability of in-store products and on-time delivery of online purchases have intensified retail competition. Nimble distribution tactics are essential to manage retail delivery and replenishment operations in such a competitive environment. This dissertation investigates two new distribution tactics for retail demand fulfillment of fast moving full-pallet products, and commit-to-delivery online purchased products. The first distribution tactic is that of the shipment of full-pallet products via a subset of retail stores instead of established distribution centers. The tactic is studied by developing a solution methodology which employs both clustering and optimization. The methodology is applied in a computational study which required generating instances for multiple U.S. census regions, and successive optimization of multiple mixed integer multi-commodity network models for each problem instance. A Java application is developed which uses US Census Zip Code population demand based data to generate retail distribution regions. The application then clusters a distribution region into several service areas. Finally it optimizes each service area separately using the IBM ILOG CPLEX libraries, and visualizes the obtained solution as well as the clustering stages of each problem instance. The computational study reveals that through-store-transshipment achieves up to 11.6% cost reduction in distribution of full-pallet products. The solution methodology can solve the model instances faster than the exact method by an order of magnitude. The second distribution tactic is the use of an alternate distribution channel for online order fulfillment. The problem of identifying online order fulfillment channels is modelled as a two-stage location-routing problem for which a heuristic solution algorithm is developed. The algorithm rests on the selection of candidate fulfillment centers first, and successive optimization of stores reassignment at subsets of fulfillment centers next. It is implemented in Java using the IBM ILOG CPLEX solver libraries with automated solution visualization using Tikz libraries. The performance of the algorithm is tested in a computational study that includes three prototypical chains of retailers with presence in New England and Mid-Atlantic, South Atlantic, and Pacific census regions. Computational tests verify the viability of the developed solution algorithm both in terms of obtained solution quality and computation time-efficiency
Why do consumers consume prosocially? : the equity exchange theory of marketing by Spencer Mitchel Ross( )

1 edition published in 2013 in English and held by 20 WorldCat member libraries worldwide

In order to satisfy consumers' needs and wants, marketers present consumers with choices of products and services through marketplace exchanges (Bagozzi 1974; 1975). Some products and services offered in marketing exchange are prosocial, forcing consumers to consider social, environmental, and economic attributes in their decision making process (Devinney, Auger, and Eckhardt 2010; Peloza and Shang 2011). Prior research in sustainability gives limited consideration to consumer-centric approaches to prosocial consumption research (Sheth, Sethia, and Srinivas 2011). Equity theory (Adams 1963; 1965), a theoretical framework established in the management literature, serves as an appropriate framework for studying how consumers are predisposed to prosocial consumption choices. This dissertation fills a gap inherent to the current, reasoned action paradigm of prosocial consumption research by 1) presenting a framework of equity exchange that helps explain prosocial consumption and 2) investigating--with respect to equity exchange--how individual difference dispositions influence prosocial consumption. This dissertation consists of two essays: In the first essay, "Equity Exchange and Consumer Sensitivity to Prosocial Choices," I present a theory of equity exchange, an operationalized construct of equity exchange--equity exchange sensitivity (Huseman, Hatfield, and Miles 1985; 1987)--and empirical support for equity exchange sensitivity's role in the prosocial consumption literature. In the second essay, "The Role of Equity Exchange Sensitivity in the Price-Perceived Quality Context," I test how equity exchange segments predict prosocial consumption preferences with respect to the price-perceived quality relationship (Levin and Johnson 1984; Rao and Monroe 1989; Zeithaml 1988). This dissertation makes several theoretical and substantive contributions. First, I assess how equity exchange theory can impact how researchers and marketers can take a consumer-centric approach to prosocial consumption behaviors. Second, I review how equity exchange sensitivity segmentation benefits both researchers and marketers in understanding how individual difference dispositions predict prosocial consumption choice. Finally, I present suggestions for future research testing the boundary conditions of equity exchange theory, including the potential to broaden its applicability beyond prosocial consumption to more general consumption decisions
Essays on human capital formation by Owen Thompson( )

1 edition published in 2013 in English and held by 20 WorldCat member libraries worldwide

This dissertation explores various aspects of human capital formation during childhood and their economic effects throughout the lifecourse. Chapter 1 investigates how the association between cognitive achievement and self-rated health in middle age differs by race, and attempts to explain these differences. Using data from the NLSY, I find that while whites with higher cognitive achievement scores tend to report substantially better general health, this relationship is far weaker or wholly absent among blacks. Further tests suggest that about 35% of this racial difference can be explained by behavioral decisions during adulthood, and that another portion of the disparity may trace back to prenatal and early childhood experiences. The chapter closes by noting that its results are broadly consistent with explanations of the racial health gap that emphasize entrenched forms of racial discrimination. Chapter 2 documents a novel gene-environment interactions by showing that the income-education association varies greatly across groups of children with different versions of a specific gene, monoamine-oxidase A (MAOA), which impacts neurotransmitter activity. For children with one MAOA variant, increases in household income have the expected positive association with education. For children with another variant, who comprise over half of the population, this relationship is much weaker. These results hold when the interactive effects are identified using genetic variation between full biological siblings, which genetic principles assert is as good as randomly assigned. Chapter 3 investigates the role of discrimination, broadly defined, in generating racial differences in home environments. To do so, I study the trends of a widely used index of the home environment (the HOME score) in a sample of mothers who were born between 1957 and 1964, and who therefore grew up in a period of rapidly declining racial discrimination in the US South. The chapter documents that HOME scores increased dramatically across these birth cohorts among Southern African American mothers, but did not increase at all among African Americans outside of the South or among Southern whites. I propose that convergence may have been due to shifts in parenting norms that were engendered by the fundamental social and economic changes occurring in the South over this period
How to understand credit spreads in credit default swaps by Xuan Che( )

1 edition published in 2013 in English and held by 20 WorldCat member libraries worldwide

This dissertation attempts to explore three new ways to understand credit spreads in credit default swaps. The first chapter investigates a hypothesis that the VIX in its role as a fear index impacts intermediary and arbitrageur capital, resulting in decreased market integration across credit and equity markets. Hedging of credit default swaps in the equity markets is found to be surprisingly ineffective. On average, hedging reduces the RMSE by 10% and the VaR by 12%. However, a passive hedge kept in place over a period as long as a month is (multifold) more effective than dynamic daily hedging. The VIX and market returns are demonstrated to predict the improvement that occurs over time. It suggests that frictionless structural models are of limited use in explaining changes in credit spreads. The second chapter attempts to quantify the extent of informed trading versus hedging trading in the CDS market. By examining the relationship between autocorrelation of CDS return and trading activities, I find that an intense trading shock predicts a large momentum in CDS spread for most of firms in my sample, which indicates that informed trading dominates hedging trading in the CDS market according to the theoretical model. The finding is not asymmetric for adverse and favorable news under my measure. However, I do find that the dominance increases ahead of the deteriorating credit conditions and with number of relationship banks in a manner consistent with the theoretical prediction. Weak condition of investment banks may limit their ability and willingness to take risky intermediary activities when firms try to access to public capital market. Credit spreads of firms may go up due to interruption of supply of credit when the market is not as perfect as indicated in theories. Empirical results in the third chapter show that the financial health condition of book runners in debt offerings has significant adverse impact on credit spreads of 133 non-financial client firms during the period from January 2002 to June 2008. Moreover, this effect is more significant for firms that have greater credit constraints and that have stronger relationship with underwriters

Three essays exploring hedge fund dynamics by Li Cai( )

1 edition published in 2011 in English and held by 20 WorldCat member libraries worldwide

Hedge fund managers are largely free to pursue dynamic trading strategies and standard static performance appraisal is no longer accurate for evaluating hedge funds. Accordingly, chapter 1 presents some new ways of analyzing hedge fund strategies following a dynamic linear regression model. Chapter 2 examines hedge fund asset allocation dynamics through conducting optimal changepoint test on an asset class factor model. Based on the average F-test and the Bayesian Information Criterion (BIC), we find that dynamic hedge funds have significantly better quality than non-dynamic funds, signaled by lower volatility in returns, stricter share restrictions, and high water mark provision. In particular, a higher degree of dynamics is shown to be associated with better risk-adjusted performance at the individual fund level. Sub-period analysis suggests that the superiority of asset allocation dynamics is mostly driven by earlier time periods before the peak of the technology bubble. Flow analysis suggests that returns in the hedge fund industry are diminishing as capital flows in and arbitrage opportunities are not infinitely exploitable. Chapter 3 examines both the self-reported classification and return-based classification on a sample of hedge funds over the period of 2005 to 2010. Using seven versions of Lipper/TASS data, we are able to track self-reported styles year by year; return-based classification follows a clustering algorithm called Partitioning Around Medoids (PAM). We show non-negligible style dynamics in both classifications, suggest that static hedge fund classification is inappropriate. Although a few self-reported categories, e.g. managed futures, appears to be consistent with the return-based grouping. We show that a hedge fund's attractiveness relative to its peers differ by different classifications. We construct a disagreement measure, quantifying how much a fund's performance percentile differs by its self-claimed classification and by its return-based classification; it is found that right tail funds in the disagreement measure perform significantly better than the left tail funds. Moreover, we find that fund flow is positively related to the disagreement measure controlling for performance and fund characteristics. The results are robust to alternative disagreement measure or extended sample period
Studies in consumer procrastination by Shabnam Haj Azim Zanjani( )

1 edition published in 2012 in English and held by 20 WorldCat member libraries worldwide

Consumer procrastination is an understudied phenomenon in marketing. Through three essays, this dissertation extends the knowledge of consumer procrastination by examining dispositional and situational causes of several constructs and behaviors related to procrastination, the subsequent impact of procrastination on marketing- relevant variables such as cognitions, experiences, emotions, and behaviors, and the role of variables that moderate the effect of procrastination. Using a multi-trait, multi-method, multi-context, and multi-sample approach, Essay 1 examines the effect of trait procrastination, the Big-Five personality factors, and the characteristics of the task at hand on procrastination behavior. The results of an online survey and a SMS-based Experience Sampling Method show that Internet-enabled procrastination explains online procrastination behavior of the younger and older generations. The findings also indicate that indecisive procrastinators are agreeable and neurotic but less conscientious and open to experience; high task procrastinators are neurotic and less open. Essay 2 examines the joint effects of trait procrastination and goal-directedness of online activities to explain how consumers experience flow online and how they respond to marketers' influence strategies. The result of an online survey shows decisional procrastination leads to greater Internet-enabled procrastination which in turn, leads to greater flow and purchase behavior. Goal-directedness increased (decreased) purchase frequency for non-procrastinators (indecisive procrastinators). The proposed model of flow re-enforces the importance of this compelling experience in increasing online purchase decisions and simultaneously provides theoretical understanding on how online procrastination acts as an addictive behavior. Essay 3 examines the market versus personality-related antecedents of consumer procrastination and its consequences in terms of post-decision cognitions, emotions and behaviors through a series of scenario-based experiments. The results indicate time limit, price uncertainty, price consciousness, sale proneness and prestige seeking positively influence consumer delay in making purchase decisions. Further, the positive impact of uncertainty is only salient when people have short time limits rather than long ones. We also found when the outcome knowledge is unpleasant, respondents who decided to wait for a better sale experience greater self-responsibility and regret but have lower intention for exit, voice or WOM compared to the people who had purchased the product

Concealed questions : in search of answers by Ilaria Frana( )

1 edition published in 2010 in English and held by 5 WorldCat member libraries worldwide

This dissertation examines the semantic interpretation of various types of DPs in so-called concealed-question (cq) constructions, as "Bill's phone number" in the sentence "John knows Bill's phone number". The peculiar characteristic of DP-CQs is that they are interpreted as having the meaning of an embedded question. So, for instance, the definite "Bill's phone number" from the example above can have the same meaning as the embedded question what "Bill's phone number is". Building on previous proposals from Heim (1979) and Romero (2005), I defend the hypothesis that CQs denote individual concepts (IC-approach). The main result of the dissertation is that (a) it provides genuinely new analyses for several types of CQs that seemed problematic for existing analyses, including quantified and indefinite CQs ("John knows every book that Mary read this summer/a doctor who can treat your illness"), and (b) it shows that the IC-approach can deliver the right results if we allow quantifier raising and adopt the copy theory of movement (Chomsky 1995) and Fox's trace conversion mechanism (Fox 1999, 2002). Chapter 1 introduces initial data on CQs and briefly discusses dissimilarities between concealed questions and their embedded question counterparts. In Chapter 2, I introduce Heim (1979) and Romero (2005)'s analysis of definite--CQs as denoting individual concepts (IC-approach). Following up on Nathan (2006), I show that the IC-approach can be extended to account for CQ-meanings of quantified DP-objects, under the assumption that the np-cq is shifted into a predicate of meaningfully sorted individual concepts (an assumption that was not required to account for CQ-meanings of definite descriptions). As discussed extensively in the course of the chapter, the assumption that common nouns must in some cases denote predicates of individual concepts has found independent motivation in the literature (Montague 1973, Nathan 2006, Romero 2007, among others). Therefore, the proposed extension of Heim and Romero's analysis to the quantified cases is fairly uncontroversial. In Chapter 3, I discuss some problems for the IC-Approach. First, I show that the analysis of quantified CQs laid out in Chapter 2 cannot be extended to quantified CQs with non-relational NPs. Second, I discuss the problematic ambiguity between "pair-list" readings and "set" readings (Heim 1979, Roelofsen and Aloni 2008) and propose that such ambiguity should be traced back to the systematic ambiguity between "transitive" and "intransitive" meanings of relational nouns. In this way, I argue that the failure of accounting for set readings under the IC-approach is just another symptom of its inability to account for non-relational NP-CQs, and that the two problems should be unified. Finally, I discuss the challenge presented by indefinite CQs with non-relational nouns. In Chapter 4, I propose an amendment to the IC-approach that accounts for the problems presented in Chapter 3. The solution relies on the copy theory of movement (Chomsky 1995) and Fox's trace conversion mechanism (Fox 1999, 2002). Overall, The main point of the chapter is to show that once we have an account for quantified CQ-readings with non-relational NPs, all the other challenges can also be taken into account. Finally, I propose that one further amendment is necessary to account for "pair-list" readings with relational nouns that are not functional.

Perceptions of principal attributes in the era of accountability by Jahmal I Mosley( )

1 edition published in 2011 in English and held by 5 WorldCat member libraries worldwide

This dissertation investigates Vermont principals' perceptions of leadership attributes linked to the role of the principal. It is guided by four research questions: (1) are there any clusters of participants who sorted the principal leadership attribute items similarly and differently; (2) how are the principal leadership attribute items within each factor ranked by the participants; (3) to what extent do the participants within each factor similarly describe the leadership attributes; and (4) to what extent do the participants within each factor find leadership attributes to be most/least characteristic of their roles? Consequently, thirty-five Vermont principals participated in Q-sort activities, which involved sorting forty-five leadership statements from the Multifactor Leadership Questionnaire (mlq). The Multifactor Leadership Questionnaire had been validated in previous studies. Participants' sorts were subjected to factor analysis to identify similarities and differences among sorts. The analysis of the data revealed the presence of two factors. Factor a members consisted of eighteen subjects who placed high value on leadership items linked to collective mission, purpose, and goal. Factor b members consisted of sixteen subjects who ranked high leadership attributes linked to collegiality and collaboration. The qualitative data provided further insight into factors' perceptions of leadership attributes. Because of the ways the factors sorted and reacted to leadership attributes, the two Factor a members were assigned the name "mission-oriented," and Factor b members were assigned the name "collaboration-oriented." The findings of this investigation revealed the emergence of the mission-oriented collaborative leadership. Under the mission-oriented collaborative leadership, school leaders witness individuals in their schools engage in fluid, genuine, reverential, and open conversations about the organization and processes group members will use to achieve community, state, and federal accountability expectations. The mission-oriented collaborative leadership style provides a synergy for meeting both the needs of the organization and the individuals who provide the human capital. Future research studies should focus on the effects mission-oriented collaborative leadership approach has on teachers' productivity, local reform efforts in the schools, and student achievement as measured by state accountability systems.

Foundations and applications of generalized planning by Siddharth Srivastava( )

1 edition published in 2010 in English and held by 4 WorldCat member libraries worldwide

Research in the field of Automated Planning is largely focused on the problem of constructing plans or sequences of actions for going from a specific initial state to a goal state. The complexity of this task makes it desirable to find "generalized" plans which can solve multiple problem instances from a class of similar problems. Most approaches for constructing such plans work under two common constraints: (a) problem instances typically do not vary in terms of the number of objects, unless theorem proving is used as a mechanism for applying actions, and, (b) generalized plan representations avoid incorporating loops of actions because of the absence of methods for efficiently evaluating their effects and their utility. Approaches proposed recently address some aspects of these limitations, but these issues are representative of deeper problems in knowledge representation and model checking, and are crucial to the problem of generalized planning. Moreover, the "generalized planning problem" itself has never been defined in a manner which could unify the wide range of representations and approaches developed for it. This thesis is a study of the fundamental problems behind these issues. We begin with a comprehensive formulation of the generalized planning problem and an identification of the most significant challenges involved in solving it. We use an abstract representation from recent work in model checking to efficiently represent situations with unknown quantities of objects and compute the possible effects of actions on such situations. We study the problem of evaluating loops of actions for termination and utility by grounding it in a powerful model of computation called abacus programs. Although evaluating loops of actions in this manner is undecidable in general, we obtain a suite of algorithms for doing so in a restricted class of abacus programs, and consequently, in the class of plans which can be translated to such abacus programs. In the final sections of this thesis, these components are utilized for developing methods for solving the generalized planning problem by generalizing sample plans and merging them together; by using classical planners to automate this process and thereby solve a given problem from scratch; and also by conducting a direct search in the space of abstract states.

Competing triggers : transparency and opacity in vowel harmony by Wendell A Kimper( )

1 edition published in 2011 in English and held by 4 WorldCat member libraries worldwide

This dissertation takes up the issue of transparency and opacity in vowel harmony--that is, when a segment is unable to undergo a harmony process, will it be skipped over by harmony (transparent) or will it prevent harmony from propagating further (opaque)? I argue that the choice between transparency and opacity is best understood as a competition between potential harmony triggers--segments are opaque when they themselves trigger spreading of the opposing feature value, and transparent when they do not. The analysis pursued in this dissertation is situated in the framework of Serial Harmonic Grammar, a variant of Optimality Theory which combines the step-wise evaluation of Harmonic Serialism with the weighted constraints of Harmonic Grammar. I argue that harmony is driven by a positively defined constraint, which assigns rewards rather than violations. Preferences for locality and for particular segmental triggers are exerted via scaling factors on the harmony constraint--rewards are diminished for non-local spreading, and increased for spreading from a preferred trigger. Evidence for this proposal comes from a diverse range of vowel harmony languages, in particular those with multiple non-participating segments which display asymmetries in their amenability to transparency. Segments more likely to be treated as opaque are also independently better triggers--they can be observed to be strong triggers in other contexts, and they are perceptually impoverished along the spreading feature dimension, which means they stand to benefit more from the perceptual advantages conferred by harmony. This proposal is also supported by experimental evidence. Results of a nonce-word discrimination task and a phoneme recall task both support the claim that harmony is perceptually advantageous; the latter suggests that this advantage obtains even among non-adjacent segments, and I argue that permitting explicitly non-local representations in harmony does not require abandoning phonetic grounding. Evidence for a trigger competition approach comes from a nonce-word study on Finnish disharmonic loanwords, which showed that vowels which are better triggers are more likely to induce transparent harmony, and less likely to be treated as transparent themselves.

Topics in the Nez Perce verb by Amy Rose Deal( )

1 edition published in 2010 in English and held by 4 WorldCat member libraries worldwide

This dissertation investigates several topics in the morphology, syntax and semantics of the Nez Perce verb and verbal clause. The first part of the dissertation focuses on the morphological segmentation of the Nez Perce verb and on the semantic description of the verb and clause. Chapter 1 provides a grammar sketch. Chapter 2 discusses the morphology, syntax and semantics of verbal suffix complexes for tense, space, aspect and modality. Chapter 3 investigates the modal suffix "o'qa," which is variously translated "can," "could (have)," "would (have)," "should," "may," and "must," and used to make circumstantial, deontic and counterfactual claims. I argue that this suffix has only a non-epistemic possibility meaning, and that apparent necessity meanings are artifacts of translation. Chapter 4 investigates the future suffix "u'," generally translated "will." Based on evidence from truth-value judgment tasks, conjunctions of "u'" sentences describing incompatible states of affairs, and negation, I argue that "u'" sentences have non- modal truth conditions. I also discuss challenges to this analysis from free choice licensing and from certain acceptable conjunctions of incompatible "u'" sentences. The second part of the dissertation explores the syntax of the verb and clause as revealed by the system of case-marking. Nez Perce case follows a tripartite pattern, with no case on intransitive subjects, and both ergative and objective cases in transitive clauses. Transitive clauses may alternatively surface with "no" case, however. I show that caseless transitive clauses in Nez Perce come in two syntactically and semantically distinguished varieties. In one variety, the subject binds a possessor phrase within the object. Chapter 6 takes up this construction together with possessor raising, which I analyze as involving movement to a [straight theta]-position. I argue that the absence of case under possessor-binding reflects an anaphor agreement effect. In the other variety of caseless clause, the object is a weak indefinite. Chapter 7 concludes that such objects are not full DPs. In chapter 8, I propose a morphological theory of case-marking which captures the cased/caseless distinction for transitive clauses. Both ergative and objective cases are analyzed as morphological results of the syntactic system of agreement.
