Does mixed frequency vector error correction model add relevant information to exchange misalignment calculus? Evidence for United States

Real exchange rate is an important macroeconomic price in the economy and a ects economic activity, interest rates, domestic prices, trade and investiments ows among other variables. Methodologies have been developed in empirical exchange rate misalignment studies to evaluate whether a real e ective exchange is overvalued or undervalued. There is a vast body of literature on the determinants of long-term real exchange rates and on empirical strategies to implement the equilibrium norms obtained from theoretical models. This study seeks to contribute to this literature by showing that it is possible to calculate the misalignment from a mixed ointegrated vector error correction framework. An empirical exercise using United States' real exchange rate data is performed. The results suggest that the model with mixed frequency data is preferred to the models with same frequency variables

The impact of OFDI on economic growth countries. An econometric approach using panel data and time-series evidence

The thesis at hand adds to the existing literature by investigating the relationship between economic growth and outward foreign direct investments (OFDI) on a set of 16 emerging countries. Two different econometric techniques are employed: a panel data regression analysis and a time-series causality analysis. Results from the regression analysis indicate a positive and significant correlation between OFDI and economic growth. Additionally, the coefficient for the OFDI variable is robust in the sense specified by the Extreme Bound Analysis (EBA). On the other hand, the findings of the causality analysis are particularly heterogeneous. The vector autoregression (VAR) and the vector error correction model (VECM) approaches identify unidirectional Granger causality running either from OFDI to GDP or from GDP to OFDI in six countries. In four economies causality among the two variables is bidirectional, whereas in five countries no causality relationship between OFDI and GDP seems to be present.

Does active management add value?: the Brazilian mutual fund market

Does active management add or destroy value? With a sample of 699 with four different main categories: stocks, fixed income, hedge and exchange rate mutual funds we conclude that the active management add value to investors in stocks and hedge funds. But in fixed income mutual funds the evidence is against the active management. We also analyze the determinants of significant alphas. For stocks and hedge funds the evidence suggests that old, big and active funds generate biggest alphas. In fixed income funds the evidence is not clear, only a positive relationship between size and alphas could be found.

A arte do fazer: o artista Ruy Meira e as artes plásticas no Pará dos anos 1940 a 1980

Este trabalho busca estudar o panorama das artes plásticas no Estado do Pará entre as décadas de 1940 e 1980 a partir da figura de Ruy Meira (1921-1995), pintor e ceramista paraense. Meira, membro de uma destacada família de homens públicos e intelectuais nortistas, desempenhou papel central no amadurecimento das artes no Pará, seja por ter sido fundamental para o estabelecimento de importantes redes de sociabilidade artístico-intelectuais, seja por ter, em sua trajetória artística, sintetizado a história da absorção das principais vertentes da arte moderna no Pará. Para estudar a personalidade artístico-social de Meira, buscamos apoio no arquivo pessoal do artista, que contém importante material, em boa parte inédito, constituído de correspondência ativa e passiva, fotografias e catálogos de exposição.

Competição inter familiar: exchange traded funds e fundos de investimentos passivos

Com o ETF passando a ser utilizado por investidores mais sofisticados e com a possibilidade de passar a ganhar representatividade, seja para uma estratégia passiva ou para uma estratégia combinada com ativos de maior risco e mais especializados, este paper busca explicar e justificar a coexistência destes veículos, que tem objetivos semelhantes, mas com estruturas diferentes. Com este objetivo, o estudo busca analisar o comportamento e a eficácia dos produtos passivos de investimentos - fundos classificados como ETF´s (sigla para Exchange-Traded Fund) e Fundos Mútuos Passivos no mercado brasileiro. Buscamos avaliar comparativamente, demonstrando diferenciações dos produtos do ponto de vista técnico, validando o comportamento dos gestores em relação a gestão passiva e de produto para os investidores finais. Apesar de literatura acadêmica recente sobre a comparatividade, o estudo busca elucidar possíveis oportunidades e aspectos relevantes para os investidores. Não é objetivo deste trabalho fazer relação comparativa entre produtos ativos de ações e os ETF´s no Brasil, apenas detalharemos o retorno obtido nos últimos períodos. O trabalho demonstra, com exemplos númericos, que o ETF torna-se um instrumento atrativo aos investidores na medida do aproveitamento de suas potencialidades, fato este com evolução relevante nos mercados da Europa e Estados Unidos, principalmente.

Forecasting Multivariate Time Series under Present-Value-Model Short- and Long-run Co-movement Restrictions

This paper has two original contributions. First, we show that the present value model (PVM hereafter), which has a wide application in macroeconomics and fi nance, entails common cyclical feature restrictions in the dynamics of the vector error-correction representation (Vahid and Engle, 1993); something that has been already investigated in that VECM context by Johansen and Swensen (1999, 2011) but has not been discussed before with this new emphasis. We also provide the present value reduced rank constraints to be tested within the log-linear model. Our second contribution relates to forecasting time series that are subject to those long and short-run reduced rank restrictions. The reason why appropriate common cyclical feature restrictions might improve forecasting is because it finds natural exclusion restrictions preventing the estimation of useless parameters, which would otherwise contribute to the increase of forecast variance with no expected reduction in bias. We applied the techniques discussed in this paper to data known to be subject to present value restrictions, i.e. the online series maintained and up-dated by Shiller. We focus on three different data sets. The fi rst includes the levels of interest rates with long and short maturities, the second includes the level of real price and dividend for the S&P composite index, and the third includes the logarithmic transformation of prices and dividends. Our exhaustive investigation of several different multivariate models reveals that better forecasts can be achieved when restrictions are applied to them. Moreover, imposing short-run restrictions produce forecast winners 70% of the time for target variables of PVMs and 63.33% of the time when all variables in the system are considered.

Temporal causality between the exchange rate and the trade balance : the case of Brazil

The paper assesses the impact of intemational relative prices and domestic expenditure variables on Brazil' s foreign trade performance in the first half of the 1990s. It has been argued that the appreciation of the Real since 1994 has had a detrimental impact of the country's trade balance. However, using temporal precedence analysis, our results do not indicate that the trade balance is strongly affected by intemational rei ative prices, such as the exchange rate. Instead, domestic expenditure variables appear to be more powerful determinant of the country' s trade performance in recent years. Granger and error correction causality techniques are used to determine temporal precedence between the trade balance and the exchange rate in the period under examination. Our findings shed light on the debate over the sustainability of recent exchange rate-anchored macroeconomic stabilisation programmes, which is a topic that has encouraged a lot of debate among academics and practitioners.
