1. Corwin-Schultz Bid-ask Spread Estimator in the Brazilian Stock Market
This paper tests the validity of the Corwin-Schultz bid-ask spread estimator in the Brazilian stock market. The Corwin-Schultz estimator arises as an easy way to compute asymmetric information throughout daily high and low stock prices for estimating overnight and non-negative adjusted spreads. The sample consisted of Ibovespa firms from 1986 to 2014 and was

2. A Common-Feature Approach for Testing Present-Value Restrictions with Financial Data
It is well known that cointegration between the level of two variables (labeled Yt and yt in this paper) is a necessary condition to assess the empirical validity of a present-value model (PV and PVM, respectively, hereafter) linking them. The work on cointegration has been so prevalent that it is often overlooked that another necessary condition for the PVM

3. ANÁLISE DA CAUSALIDADE E COINTEGRAÇÃO ENTRE VARIÁVEIS MACROECONÔMICAS E O IBOVESPA / ANALYSIS OF CAUSALITY AND COINTEGRATION BETWEEN MACROECONOMIC VARIABLES AND IBOVESPA
The aim of this work was to assess the causality relation among the set of macroeconomic variables, represented by interest and exchange rates, inflation and Industrial Production Index as proxy of the Gross Internal Product regarding São Paulo Stock Exchange Index (IBOVESPA).

4. Delimitação de mercado usando testes baseados em preço: uma análise econométrica

5. Exchange rate dynamics in Brazil
The paper aims to investigate on empirical and theoretical grounds the Brazilian exchange rate dynamics under floating exchange rates. The empirical analysis examines the short and long term behavior of the exchange rate, interest rate (domestic and foreign) and country risk using econometric techniques such as variance decomposition, Granger causality, coin

6. Análise do mecanismo de transmissão dos preços internacionais de commodities agrícolas sobre o comportamento da taxa de câmbio real no Brasil
This paper examined the transmission mechanism of international prices of agricultural commodities into the real exchange rate in Brazil for the period from January 2000 to February 2010. We used time series models (ARIMA Model, Transfer Model, Intervention Analysis, Johansen Cointegration Test) in determination of the short and long run elasticities. Transf

7. Infrastructure and productivity in Latin America: is there a relationship in the long run?
This article analyses the relationship between infrastructure and total factor productivity (TFP) in the four major Latin American economies: Argentina, Brazil, Chile and Mexico. We hypothesise that an increase in infrastructure has an indirect effect on long-term economic growth by raising productivity. To assess this theory, we use the traditional Johansen

8. Human capital and innovation: evidence from panel cointegration tests
Panel cointegration techniques applied to pooled data for 27 economies for the period 1960-2000 indicate that: i) government spending in education and innovation indicators are cointegrated; ii) education hierarchy is relevant when explaining innovation; and iii) the relation between education and innovation can be obtained after an accommodation of a level

9. Apreçamento racional de mercadorias utilizando modelo de valor presente para o boi gordo no período de 2001 a 2008
Campbell and Schiller (1987) proposed, within the scope of econometric analysis and cointegration, a powerful tool that enabled the present value model tests to also test market rationality and efficiency. The opportunity offered by the present value model of a substantial and settled fundamental value theory together with a powerful tool kit of empiricaleco

10. Hysteresis in brazilian manufactured exports: a panel cointegration analysis / Hysteresis nas exportações manufaturadas brasileiras: uma análise de cointegração com dados em painel
In spite of the recent fall of the growth rate of Brazilian exports, the response of external sales to the appreciation of the exchange rate has been slower than what was predicted by economic theory. These evidences suggest that deviations from a long-run relationship between exchange rate and exports may take longer to be corrected, motivating the investig

11. Uma abordagem da hipótese da neutralidade da moeda usando dados do Brasil pós-Real / An approach to the hypothesis of neutrality of money using data from Brazil after the Real Plan
The hypothesis of neutrality of money is the theoretical framework of the Quantity Theory of Money (QTM), which is based from the Fishers equation of exchange, assuming that the income-velocity of money is constant, the real output is exogenously determined by nonmonetary variables, such as technology, capital stock and labor supply. But the real output is t

12. Análise do modelo de valor presente entre preços das ações e dividendos para o mercado financeiro no Brasil: evidência baseada nos dados em painel dinâmico
A Hipótese de Eficiência de Mercado tem sido a proposição central das finanças durante muitos anos, com o desenvolvimento de razões teóricas poderosas explicando porque a hipótese deveria permanecer. A partir da década de 30, destacam-se os primeiros trabalhos relacionados à análise de títulos, surgindo a idéia de que o valor fundamental de qual
