    Technology and the Changing Family: A Unified Model of Marriage, Divorce, Educational Attainment and Married Female Labor-Force Participation

    Marriage has declined since 1960, with the drop being bigger for non-college educated individuals versus college educated ones. Divorce has increased, more so for the non-college educated vis-à-vis the college educated. Additionally, assortative mating has risen; i.e., people are more likely to marry someone of the same educational level today than in the past. A unified model of marriage, divorce, educational attainment and married female labor-force participation is developed and estimated to fit the postwar U.S. data. The role of technological progress in the household sector and shifts in the wage structure for explaining these facts is gauged.

    Marry Your Like: Assortative Mating and Income Inequality

    Get PDF
    Has there been an increase in positive assortative mating? Does assortative mating contribute to household income inequality? Data from the United States Census Bureau suggests there has been a rise in assortative mating. Additionally, assortative mating affects household income inequality. In particular, if matching in 2005 between husbands and wives had been random, instead of the pattern observed in the data, then the Gini coefficient would have fallen from the observed 0.43 to 0.34, so that income inequality would be smaller. Thus, assortative mating is important for income inequality. The high level of married female labor-force participation in 2005 is important for this result

    An Equilibrium Model of the African HIV/AIDS Epidemic

    Get PDF
    Eleven percent of the Malawian population is HIV infected. Eighteen percent of sexual encounters are casual. A condom is used one quarter of the time. A choice-theoretic general equilibrium search model is constructed to analyze the Malawian epidemic. In the developed framework, people select between different sexual practices while knowing the inherent risk. The analysis suggests that the efficacy of public policy depends upon the induced behavioral changes and general equilibrium effects that are typically absent in epidemiological studies and small-scale field experiments. For some interventions (some forms of promoting condoms or marriage), the quantitative exercise suggests that these effects may increase HIV prevalence, while for others (such as male circumcision or increased incomes) they strengthen the effectiveness of the intervention. The underlying channels giving rise to these effects are discussed in detail

    O objetivo deste trabalho é apresentar uma proposta de modelo de desempenho de processos educacionais com mensuração e aplicação em instituições de ensino superior - IES, capaz de beneficiá-las, evitando desperdício de trabalho, tempo e recursos envolvidos. Trata-se de um estudo de caso, no qual foi utilizado como objeto de estudo um Centro Universitário Comunitário, localizado na região da Grande São Paulo. As IES comunitárias são identificadas por suas gestões participativas e democráticas. Estas instituições de caráter público não estatal apresentam-se como um modelo alternativo de ensino superior, com uma determinação no desenvolvimento de ações em benefício da coletividade. Os procedimentos metodológicos utilizados foram a pesquisa bibliográfica - na qual buscouse estudar as análises de conceitos de custos, custeio e processos; a coleta dos dados e o mapeamento dos processos educacionais. As informações colhidas foram transformadas em demonstrações de resultados e a proposta de modelo de desempenho de processos educacionais foi realizada. Adaptando-se às características de uma IES, foi criado o termo unidade de responsabilidade , o qual refere-se a um centro de responsabilidade, tratando-se nesse caso dos cursos oferecidos pela instituição. Como resultado da pesquisa, apresenta-se que a ação tomada para evitar desperdícios e melhorar o resultado econômico foi a junção de disciplinas que atingiu os Custos Diretos de Ensino. Concluiu-se que essas melhorias através de processos educacionais apresentaram uma significante economia de recursos para a instituição

    Este artigo tem por base a publiCIDADE e as mudanças históricas da construção da marca do Banco da Amazônia (BASA), por meio das mensagens publicitárias veiculadas ao longo de mais de sete décadas de existência da instituição financeira (banco). Assim, buscamos estudar a construção das marcas do banco (Banco de Crédito da Borracha, Banco de Crédito da Amazônia, BASA e Banco da Amazônia) como uma personalidade representativa do progresso e do desenvolvimento da região amazônica, como lugar de pertencimento das populações atendidas e atingidas pelos projetos financiados pelo banco estatal e suas iniciativas institucionais publicizadas com o intuito de promover, publicitariamente, o(s) discurso(s) de progresso e de desenvolvimento da Amazônia
