The marginal cost of funds from public sector borrowing

An expression for the welfare cost of a marginal increase in the public debt is derived using a simple AK endogenous growth model. This measure of the marginal cost of public funds (MCF) can be interpreted as the marginal benefit-cost ratio that a debtfinanced public project needs in order to generate a net social gain. The model predicts an increase in the public debt ratio will have little effect on the optimal public expenditure ratio and that most of the adjustment will occur on the tax side of the budget.

Gestão contemporânea de carreira: um estudo de caso com peritos criminais do Instituto Nacional de Criminalística da Polícia Federal

Nas últimas três décadas, intensificou-se na academia o debate sobre o tema gestão de carreiras. As transformações sociais, econômicas, tecnológicas e sua influência sobre o mercado de trabalho aguçaram o interesse dos pesquisadores organizacionais em entender como os indivíduos conduzem suas carreiras nesse novo cenário. A noção da responsabilidade pessoal na administração da própria carreira torna-se relevante, diminuindo o papel da organização nesse processo. Flexibilidade, autoconhecimento e abertura à mobilidade no trabalho são novos requisitos. Surgem na literatura dois modelos que bem expressam essa realidade: a carreira proteana e sem fronteiras. Este estudo teve como objetivo explorar de que forma servidores públicos federais da área de segurança pública – os peritos criminais do Instituto Nacional de Criminalística da Polícia Federal – gerenciam suas carreiras à luz de tais fenômenos, considerando o ambiente organizacional tradicional no qual estão imersos. Aspectos de comprometimento e entrincheiramento na carreira também foram considerados. Optou-se pela estratégia qualitativa com uso de estudo de caso e pesquisa documental. Foram realizadas onze (11) entrevistas em profundidade, cujo conteúdo foi analisado de acordo com uma grade temática pré-estabelecida. Os resultados revelam que atitudes de carreira proteana e sem fronteiras são identificadas mesmo com a rigidez do modelo administrativo de carreira do serviço público federal. Além disso, há indícios de entrincheiramento voluntário na carreira, sem, no entanto, afetar o comprometimento com a carreira. A pesquisa pretende abrir novas possibilidades de entendimento sobre o tema no setor público, em especial na área de segurança pública, considerando as peculiaridades de suas carreiras.

The impact of public capital and public investment on economic growth: an empirical investigation

in this anicle we measure the impact of public sector capital and investment on economic growth. Initially, traditional growth accounting regressions are run for a cross-country data set. A simple endogenous growth model is then constructed in order to take into account the determinants of labor, private capital and public capital. In both cases, public capital is a separate argument of the production function. An additional data-set constructed with quarterly American data was used in the estimations of the growth mode!. The results indicate lhat public capital and public investment play a significant role in determining growth rates and have a significant impact on capital and labor returns. Furthermore, the impact of public investment on productivity growth was found to be positive and always significant for bolh samples. Hence. in a fully optimizing modelo we confmn previous results in the literature that lhe failure of public investment to keep pace with output growlh during the Seventies and Eighties may have played a major role in the slowdown of lhe productivity growth in the period. Anolher main outcome concems the output elasticity wilh respect to public capital. The coefficiem estimates are always positive and significant but magnitudes depend on each of lhe two data set used.

From public to private : the performance of former public workers in the Brazilian labor market

This paper analyzes the placement in the private sector of a subset of Brazilian public-sector employees. This group left public employment in the mid-1990’s through a voluntary severance program. This paper contrasts their earnings before and after quitting the public sector, and compares both sets of wages to public and private sector earnings for similar workers. We find that participants in this voluntary severance program suffered a significant reduction in average earnings wage and an increase in earnings dispersion. We test whether the reduction in average earnings and the increase in earnings dispersion is the expected outcome once one controls for observed characteristics, by means of counterfactual simulations. Several methods of controlling for observed characteristics (parametric and non-parametrically) are used for robustness. The results indicate that this group of workers was paid at levels below what would be expected given their embodied observable characteristics.
