Empirical Essays on Poverty, Inequality, and Social Welfare

McCaig, Brian 19 February 2010 (has links)
This thesis consists of three empirical chapters related to distributional outcomes, such as poverty and inequality, in three different contexts. Chapter 1 outlines a class of statistical procedures that permit testing of a broad range of multidimensional stochastic dominance hypotheses. We apply the procedures to data on income and leisure hours for individuals in Germany, the UK, and the USA. We find that no country first-order stochastically dominates the others in both dimensions for all years of comparison. Furthermore, while in general the USA stochastically dominates Germany and the UK with respect to income, in most periods Germany stochastically dominates with respect to leisure hours. Finally, we find evidence that bivariate poverty is lower in Germany than in either the UK or the USA. On the other hand, poverty comparisons between the UK and the USA are sensitive to the subpopulation of individuals considered. Chapter 2 provides a detailed description of the evolution of income inequality in Vietnam between 1993 and 2006. We construct consistent estimates of annual household income using five nationally representative household surveys. Our main finding is that Vietnam’s rapid growth was accompanied by a reduction in inequality between 1993 and 2002 and an unchanged level of inequality between 2002 and 2006. We find that strong growth in employment income and robust growth of cropping income played an important role in decreasing rural inequality, while the growth of wage income and the stagnation of household business income similarly contributed to the reduction in urban inequality. Chapter 3 examines the impacts of the 2001 U.S.-Vietnam Bilateral Trade Agreement on provincial poverty level in Vietnam. My main finding is that provinces that were more exposed to the U.S. tariff cuts experienced faster decreases in poverty between 2002 and 2004. I subsequently explore three labour market channels from the trade agreement to poverty alleviation. Provinces that were more exposed to the tariff cuts experienced (1) increases in provincial wage premiums for low-skilled workers, (2) faster movement into wage and salaried jobs for low-skilled workers, and (3) more rapid job growth in formal enterprises.

Assessing the demand for phytosterol-enriched products

Yuan, Yan 15 May 2009 (has links)
Phytosterol is a healthful ingredient that helps reduce blood cholesterol levels. It has been over ten years since the first phytosterol-enriched product, Benecol margarine, was launched in Finland in 1995; however, understanding of this product is still limited. In addition, it has been shown in the literature that health-related concerns have an influence on consumers’ decisions to consume harmful or beneficial ingredients. This study estimates the demand for three phytosterol-enriched products in the categories of margarine, orange juice and yogurt. The objectives of this study are (1) to estimate price and expenditure elasticities for phytosterol-enriched brands and comparative non-phytosterol brands, (2) to identify cannibalization effects with a proposed methodology, and, (3) to estimate the welfare effects associated with the introduction of a product. Subsuming LA/AIDS, Rotterdam, CBS and NBR demand systems, the Barten synthetic demand system is applied to margarine weekly scanner data. Phytosterol-enriched margarine brands (Benecol and Take Control) commanded significantly higher prices relative to other margarine brands. Strong substitutability among the phytosterol brands was evident as suggested by the statistically significant and relatively large compensated cross-price elasticities. Cannibalization is defined as the competition between products offered by the same firm. Cannibalization studies are important to multi-product firms because they provide insights into the benefits of offering product variety. In addition, the identification and assessment of cannibalization are integral factors for strategic decisions of new product introductions. However, there are no standard measures to identify its effects. We use the Barten synthetic demand system along with two conventional measures to illustrate that the use of cross-price elasticities derived from a flexible demand system is a viable alternative to identify cannibalization effects. The third objective analyzes the consumer welfare effects associated with a new functional food product introduction. Using the Barten synthetic model and pre- and post-introduction scanner data, we estimate direct price and variety effects associated with the introduction of a new functional food product (i.e., phytosterol-enriched product). With post-introduction data and an assumed demand structure, we also estimate indirect price effects. Our results suggest notable welfare effects consisting of a relatively small price effect and a large variety effect.

Bull-switching in African Bovid Herds: Assessing Best Practices for Breeding Management in Waterbuck

Jones, Renee Crystal Michelle 2010 August 1900 (has links)
To implement sustainable ex-situ management of big ungulate herds such as African Waterbuck (Kobus ellipsiprymnus), one strategy is to place a vasectomized male with females during the sub-optimal season for breeding and subsequently replace him with an intact male during the optimal breeding season. However, information is needed on the effects of vasectomy and the long-term effects on social well-being of individuals used in this "bull-switching" treatment, which is designed to enhance well-being of the whole herd. In this study, behavioral observations were conducted in three periods (pre-treatment, treatment, post-treatment) 2-months in length. Focal individual observations were used to systematically record (a) continuous samples on video (6-min duration; n = 595), (b) instantaneous samples of proximity (n = 951), and (c) field notes of all-occurrences of social interaction (courting and antagonistic). The quantitative and qualitative analyses revealed a significant effect of treatment on three (courtship, escalation, and proximity) out of four measures (deescalation was not affected). Courtship and escalation behaviors increased significantly during the treatment (G2 = 46.35; df=1, P <0.001; z=6.60). The treatment was associated with a significant change in proximity for females (G2 = 17.21; df=1; P <0.001; z=2.31) and other males (G2 =16.10; df=1; P <0.001; z=-3.57). Overall, (1) there was no substantial change with social well-being of the vasectomized male before removal and after reintroduction; (2) the male proximity did not fluctuate significantly with the juvenile males, calves, and other species; and (3) the vasectomized male and the intact male exhibited similar social well-being characteristics. Considering current environmental changes, the treatment did not result in a decline of the social well-being of females and calves, but it did for non-breeding males. Courtship declined in post-treatment, but this was due to the increased percent of pregnant females. During post-treatment, a change in ratio of green grass and supplementary feed pellets possibly affected de-escalation in the context of interspecies interactions. The change of the proximity of the herd was associated with increased heat and use of shaded areas in the pasture. The treatment resulted in a change in relationship with the satellite male and juvenile males in the herd.

Successful reentry into the workplace: a case study of the experiences of female welfare recipients participating in two job training programs

Tucker, Jo B. 25 April 2007 (has links)
This case study investigated eight welfare recipients and their perceptions of the effectiveness of the job training programs in which they participated in an effort to understand the domains in which welfare-reliant individuals exhibit a commitment to work. Specific issues addressed by this qualitative study included the individuals' perceptions of (1) the program effects on escaping poverty and becoming self-sufficient; (2) the impact of the program focus on the participants' achievement and empowerment; (3) employment and the prospects of getting off welfare, both before and after program completion; and (4) recommendations for improvement in designing such programs. It is clear that all participants in the study found resolution to the tensions in their lives through the programs. Life skills training was critical in enhancing the self-esteem of the participants, providing them the tools necessary to overcome their fear of independence and allowing them to experience their own definition of success. Each participant in the study wished for more time in the program. Most participants felt the program was a gift and verbalized the value of supportive services on-site.
