Working Paper Estimando os gastos privados com educação no brasil(2011) NAERCIO AQUINO MENEZES FILHO; Nuñez, Diana FeketeEste artigo estima, pela primeira vez na literatura, os gastos totais privados com educação no Brasil, utilizando os micro-dados de gastos das famílias brasileiras da Pesquisa de Orçamentos Familiares para os anos de 2002/2003 e 2008/2009. Verificamos que as famílias brasileiras gastaram 1,9% do PIB com educação em 2002/03 e 1,3% em 2008/09. Uma comparação com outros países mostra que os gastos privados e públicos são maiores que a média dos países da OCDE. Os gastos com educação não estão relacionados com o desempenho escolar médio dos países, medido pelos últimos resultados do exame internacional PISAWorking Paper Modelo Multi-Estado de Markov em Cartões de Crédito(2008) RINALDO ARTES; Régis, Daniel EvangelistaModelos multi-estado de Markov são utilizados na área médica para estimar as probabilidades de transição entre, por exemplo, vários estágios de uma doença, podendo o paciente recuperar-se ou morrer. O principal interesse deste trabalho é analisar a aplicação do modelo multiestado de Markov na área de risco associado ao uso de cartões de crédito, aproveitando as características de transições entre diversos estados de relacionamento entre os clientes e as instituições ao longo do tempo e, com isso, gerar modelos de escore para diversos fins. Modelos de regressão logística também são estimados a fim de comparar os resultados com os obtidos pelo modelo multi-estado de Markov.Working Paper A crise política de 2005: Causas estruturais e conjunturais que a explicam(2008) CARLOS ALBERTO FURTADO DE MELOWorking Paper Appropriability and Complementarities in a Fragile Patent System: Evidence from Brazilian Manufacturin(2013) Barros, Henrique MachadoWorking Paper The Usefulness of Financial Variables in Predicting Exchange Rate Movements(2013) Rossi Junior, Jose LuizThis paper studies the predictive power of several financial variables usually used as proxies for global liquidity, volatility, and risk aversion in forecasting exchange rates for a set of countries from January 2001 to April 2013. The results indicate that changes in the long-term interest rate, in the VIX, in the high yield spread, and in the market liquidity indicators have strong in-sample and out-of-sample predictive power with respect to exchange rates. The results indicate that the relationship between the financial variables and the exchange rate is relatively stable. The paper shows that the predictability of the models is persistent over time and does not depend on the choice of the window size adopted in the forecasting exercises.Working Paper Replacement Cycles, Income Distribution, and Dynamic Price Discrimination(2013) EDUARDO CORREIA DE SOUZA; Batista, Jorge ChamiWorking Paper Management of Intellectual Property in Brazilian Universities: a Multiple Case Study(2013) Pojo, Sabrina Da Rosa; Vidal, Valéria Schneider; Zen, Aurora Carneiro; Barros, Henrique MachadoOriginally established to incentivize individual inventors the patent system became broadly used by corporations, and has been increasingly used by universities worldwide. In Brazil, this is not different; especially in recent years when public policy has attempted to more directly foster innovation in the country. However, little is known as to the extent that universities in Brazil are able to coordinate patent-related activities and to facilitate knowledge transfer. On the basis of multiple case studies this paper explores how publicly-funded universities in Brazil are equipping themselves to deal with intellectual property rights (IPR) as well as technology licensing. The studied cases suggest that despite significant amount of patents applications, Brazilian universities present many differences in the management of their intellectual property. In particular, universities’ TTOs seem to play a central role in university productivity when it comes to patenting and knowledge transfer.Working Paper Tecnologia da Informação e Eficiência Bancária no Brasil(2013) Mainetti Junior, Sergio; Gramani, Maria Cristina Nogueira; Barros, Henrique MachadoApesar de ser inegável a transformação proporcionada pela tecnologia da informação (TI) para a sociedade, a compreensão dos seus efeitos ainda é objeto de estudo. Este artigo aborda o impacto das despesas com TI na eficiência do setor bancário no Brasil. A novidade deste trabalho é que ele utiliza uma segmentação do setor bancário de tal modo que uma das pressuposições da técnica empírica não seja violada. A amostra conta com 37 bancos, os quais representam cerca de 70% dos ativos do Sistema Financeiro Nacional e que são agrupados em três categorias: varejistas, atacadistas e especializados em crédito. Por meio da técnica de análise envoltória de dados, os resultados mostram que a TI tem impacto distinto na eficiência dos segmentos bancários. Os resultados da pesquisa empírica revelaram que as despesas com TI parecem importar mais para a eficiência dos bancos varejistas do que para a eficiência dos bancos nos outros dois segmentos.Working Paper Trade, structural transformation and growth in China(2013) Ferreira, Pedro Cavalcanti; MARCELO RODRIGUES DOS SANTOS; Silva, Leonardo Fonseca daChina's recent performance in economic growth was characterized by high investment rate, increase in international trade, strong productivity growth in agriculture and nonfarm sectors and the reallocation of labor across sectors. We present a standard dynamic general equilibrium model of structural transformation for the Chinese economy to assess the contributions of the main drivers for the Chinese economic development. Our paper di§ers from other contributions to the literature by adding an external sector to the general equilibrium model of structural transformation. By doing that, we are able to estimate the contribution of trade to the economic development of China. We estimate that the contribution of trade to Chinaís economic growth was 26% of total economic growth during the period from 1980-2005. Moreover, the agricultural sector explained 27% of Chinese economic performance from 1980 to 2005.Working Paper Liquidity and Exchange Rates(2013) Rossi Júnior, José LuizThis paper studies the predictive power of several proxies for liquidity in forecasting exchange rates for a set of countries from January 2001 to April 2013. The results indicate that changes in funding liquidity of U.S. financial intermediaries impact exchange rates around the globe; however, the type of funding and its relevance in explaining exchange rate movements vary across time. Public liquidity represented by U.S. monetary aggregates is not robustly significant in forecasting exchange rate changes across time, countries or forecasting horizons. By contrast, the long-term interest rate and risk taking indicators have robust in-sample and out-of-sample predictive power with respect to exchange rates. Finally, the paper confirms that dynamic factors extracted from a panel of several liquidity indicators are useful in predicting exchange rate movements.
