Our study estimates the crowd-out of private health insurance following SCHIP expansions for children. We use panel data from the 2001 panel of the Survey of Income and Program Participation (SIPP). We use multivariate regression models to the crowd-out of private health insurance. This difference-in-differences approach controls for other factors that affect both the control group and treatment group, and measures the extent of crowd-out private coverage in the treatment group relative to the control group. We find that nearly 26 percent of the transitions from private coverage into SCHIP coverage were made by children who would have had private coverage in the absence of the expansions. This paper provides evidence that the SCHIP expansions have overall displacement effect of 52.9 percent for private coverage for those children who had private coverage or were uninsured from the first interview in 2001. This dissertation provides empirical evidence on the impact of SCHIP on single mothers¡¯ working decisions using recent CPS (Current Population Survey) data during 1999-2005. The empirical work requires a measure of the change in eligibility requirements; we compute a measure suggested by Yelowitz (1995). The major findings of this paper are: first, SCHIP expansions are found to have a significant positive impact on hours-worked decision; second, most models yielded results that indicated that SCHIP expansions have a generally insignificant impact on the decision to work.

This dissertation extends the literature on the crowd-out theory to international nonprofits based in the United States. The dissertation measures the simultaneous impact of government grants on private contributions and fundraising activities of INGOs. Understanding the relationship of the major players (government, donors and nonprofit managers) in revenue collection of INGOs is important in understanding international charity and its implications. Six major sub-categories of international organizations have been identified for this research. These are based on a review of the literature on international organizations and those already coded as international according to the National Taxonomy of Exempt Entities (NTEE). An overview of the INGO sub-categories, their description and coding can be seen in table A5 in appendix A. The major sub-categories include (1) International, Foreign Affairs and National Security (ifans), (2) Promotion of International Understanding (piu), (3) International Development (id), (4) International Peace and Security (ips), (5) International Human Rights (ihr), and (6) International, Foreign Affairs and National Security N.E.C. (ifansNEC). We will employ a panel dataset of INGOs between the years 1998 and 2003 to test for crowding-out effect of government grants on private contributions and fundraising activities. We have a total of 2,169 INGOs in our data set and a total of 6,239 observations.

This dissertation consists of three empirical essays on labor, health, and real estate economics. The first essay theoretically and empirically analyzed the effects of the costs of firing an employee and hiring a replacement in a labor market with imperfect information. The theory suggested that increased expected firing or replacement costs contributed to a ``lemons effect" for the fired worker through the negative signal received in the labor market regarding the worker's ability. To test this theory, data from the Displaced Worker's Supplement to the Current Population Survey from 2004 to 2014 was used. The results were mixed, but suggested that workers in the United States who were displaced from their job experienced decreased probabilities of finding reemployment as firing costs increased. The essay also examined whether this ``lemons effect" contributed to larger wage decreases, but the estimates did not support this conclusion. The second essay estimated the impacts of the 2001 elimination of the Medicare 24-month waiting period for non-elderly Amyotrophic Lateral Sclerosis (ALS) patients. Using data from the National Hospital Discharge Survey, this essay estimated the effects of the elimination on health insurance coverage and utilization of health care services. By applying a difference-in-difference OLS estimation technique, it was estimated that, as a result of the waiting period elimination, non-elderly ALS patients were more likely to be insured, but there was a significant crowd-out of private insurance. These non-elderly patients who were admitted to the hospital with serious symptoms were also more likely to be transferred to long- or short-term care facilities while non-serious patients were more likely to receive a high (four or more) number of medical services while hospitalized. In the third essay, the effects of a new suburban casino on local housing prices were evaluated. Similar to the second essay, a difference-in-difference approach was applied, but it was combined with a spatial hedonic pricing model. Using data from a GIS product from the Maryland Department of Planning and local-area data from the American Community Survey, the effects that the opening of Maryland Live! Casino had on home sales prices of properties located in primary (one-mile radius) and secondary (one to three miles) impact areas were estimated. The results of the estimations indicated that the opening of the casino had a positive impact on housing prices in the primary impact area and this impact likely began during the construction period. No impacts, however, were evident in the secondary impact area. / Economics

This research assessed the short- and long-term effectiveness of a private nutrition company’s promotion initiative in school cafeterias in Belo Horizonte, Brazil. Two hundred and eight children and adolescents from 3 schools participated in a short-lived, lottery-based incentives program contingent on the purchase of locally promoted healthy products. One hundred and forty-four children and adolescents from a fourth comparable school served as controls. A multilevel model compared the average number of promoted healthy products purchased daily per participant before (26 weekdays), during (9 weekdays), and after (28 weekdays) the intervention period. The results indicate a clear short-term effect. The incentives program significantly increased the purchase of promoted healthy products during (vs. before) the intervention period in the treated schools, specially among girls and younger children. On average, no long-term effect was observed. The purchase of the promoted healthy products returned to pre-intervention levels immediately after the removal of the incentives program. Interestingly, a detailed analysis revealed a rather heterogeneous long-term effect based on past consumption behavior. The incentive promoted a positive long-term effect on the children who had never consumed the incentivized healthier products prior to the intervention, whereas a negative long-term effect was noted for the already habitual consumers of the targeted healthier products. Past consumption behavior must be taken into consideration for a complete understanding of the long-term effects of incentives on healthier eating. / O impacto de incentivos econômicos sobre a alimentação saudável não é claro, particularmente no longo prazo (ou seja, após o período da intervenção). Esta pesquisa avaliou a eficácia de curto e longo prazo de uma iniciativa de promoção de uma empresa de nutrição privada em cantinas escolares em Belo Horizonte, Brasil. Duzentas e oito crianças e adolescentes de três escolas participaram de um programa de incentivos de curta duração baseado em um sorteio, condicionado à compra de produtos saudáveis promovidos localmente. Cento e quarenta e quatro crianças e adolescentes de uma quarta escola comparável serviram como controles. Um modelo multinível comparou o número médio de produtos saudáveis promovidos adquiridos diariamente por participante antes (26 dias úteis), durante (9 dias úteis) e após (28 dias úteis) o período da intervenção. Os resultados indicam um efeito claro de curto prazo. O programa de incentivos aumentou significativamente a compra de produtos saudáveis promovidos durante o período da intervenção (vs. antes) nas escolas tratadas, especialmente entre as meninas e crianças mais novas. Em média, nenhum efeito de longo prazo foi observado. A compra dos produtos saudáveis promovidos retornou aos níveis pré-intervenção imediatamente após a remoção do programa de incentivos. Curiosamente, uma análise detalhada revelou um efeito bastante heterogêneo de longo prazo baseado no comportamento prévio de consumo dos indivíduos. O incentivo promoveu um efeito positivo de longo prazo sobre as crianças que nunca haviam consumido os produtos promovidos e saudáveis antes da intervenção, ao passo que um efeito negativo de longo prazo foi observado para os consumidores já habituais dos produtos mais saudáveis visados. O comportamento do consumo passado deve ser levado em consideração para uma melhor compreensão dos efeitos de longo prazo de incentivos sobre uma alimentação mais saudável.

過去四十年， 我國經濟快速成長， 國民所得不斷提高，　公共部門的經 費不斷增加， 但所提供的公共財貨與勞務的數量與品質，卻遠落後於人 民期望之後， 這是造成投資環境惡化、 私人投資(private investment) 意願低落、 及生活素質低落的主要因素之一。 目前台灣地區諸多經濟與 社會結構失衡問題的癥結，在於公共投資(public investment)政策反應 社會需求的速度過於遲緩。因此， 深入了解台灣地區公共投資的情形， 對於我國解決目前所面臨的經濟問題、 追求進一步的經濟成長、及提升 生活素質將有很大的助益。然公共投資是整體投資活動的一環， 與私人 投資同是支持經濟成長的重要角色。 公共投資增加是否會排擠私人投資 ， 需視兩種相對力量大小而定。 一方面較高水準公共投資對私人投資產 出排擠(cro wd-out)；但某些公共資本主要在提供公共基礎設施，藉此可 降低私人的生產成本， 提升私人投資意願。 若公共投資增加， 致使私 人投資減少則排擠產生； 再者公共投資提供的公共基礎設施， 輔助私經 濟的運作， 使私人的邊際生產力提升， 進而使私人投資增加， 則誘導( crowd-in)產生。本篇論文共分為五個部分， 依序為諸論、 公共投資與 私人投資之文獻回顧 、 台灣地區公共投資的回顧、 公共投資與私人投 資關係的實證分析、 及結論。

Esse trabalho teve como objetivo contribuir para o debate sobre a importância das políticas de incentivo à inovação no Brasil. Os resultados esperados do uso que as empresas fizeram dos diferentes tipos de instrumentos sobre os gastos em pesquisa e desenvolvimento (P&D) foram avaliados pelo método de diferenças em diferenças. O método permitiu obter as diferenças de gastos entre empresas beneficiárias de instrumentos e as não-beneficiárias em três períodos consecutivos: 2005 em relação à 2003; 2008 em relação à 2005 e de 2011 em relação à 2008. Ao fazer isso, foi possível identificar se tais diferenças foram positivas e significativas, podendo ser atribuídas às influências dos instrumentos. Os instrumentos utilizados foram: incentivos fiscais, Lei de Informática, financiamentos em parcerias, financiamentos sem parcerias e subvenção. E a utilização dos mesmos pelas empresas teve maior relevância no âmbito de diversos programas de apoio à inovação vigentes no país a partir da retomada das políticas industriais e tecnológicas, nos anos 2000. O estudo concluiu que os efeitos positivos e significativos são limitados à determinados grupos tecnológicos e à poucos instrumentos, em geral, de caráter fiscal. Além disso, esses efeitos positivos surgem em apenas um período, sendo que para cada grupo tecnológico foram efetuadas estimativas para três períodos. Também não houve evidências de que os instrumentos financeiros exerçam efeitos significativos sobre as decisões de gastos em pesquisa e desenvolvimento, apesar da maior ênfase dada aos mesmos no período estudado. Os resultados sugerem fraca influência dos mecanismos de apoio à P&D no Brasil sobre o aumento dos gastos privados, apesar dos avanços recentes. / This study aimed to contribute to the debate about the importance of encouraging innovation policies in Brazil. Understanding the role played by public support instruments to research and development activities in relation to private business spending has become fundamental to achieving this end. The expected results of the use that companies made of different types of instruments on spending were evaluated by the method of difference in differences. This allows you to compare, over a certain period of time, the differences in expenses between the companies that made use of any type of instrument and the companies that did not. Thus, the method yielded differences in spending between the beneficiary and nonbeneficiary firms of those instruments of three consecutive periods: 2005 compared to 2003; 2008 compared to 2005 and 2011 compared to 2008. In doing so, it was possible to identify whether these differences were positive and significant and can be attributed to the influence of the instruments. The instruments used were: tax incentives, Information Technology Law, financing partnerships, financing and grants. And their use by companies had most relevance within various programs to support innovation in force in the country from the resumption of industry and technology policy in the 2000s. The study concluded that the positive and significant effects are limited to certain technological groups and the few instruments in general tax character. In addition, these positive effects arise in one period, and for each technology group estimates were made for three periods. There was also no evidence that the financial instruments carry significant effects on spending decisions on research and development, despite the greater emphasis given to them during the study period. The results suggest weak influence of mechanisms to support R&D in Brazil on the rise in private spending, despite progress in recent years.
