The intention of the present work is to evaluate long-run relations in the stock markets of six Latin American countries (Argentina, Brazil, Chile, Colombia, Mexico and Peru) and the United States stock market, by means of a model in which a cointegration relation exists between the principals...

This study examines the Koehler and Symanovski copula function with specific marginals, such as the skew Student-t, the skew generalized secant hyperbolic, and the skew generalized exponential power distributions, in modelling financial returns and measuring dependent risks. The copula function...

We investigate a link between the performance of several security indexes in broad investment categories and investor attention as measured by Google search probability. We find that there is a significant short-term change in index returns following an increase in attention. Conversely, a shock...

In this article copula theory is used to analyze the co-movements between the Brazilian and American capital markets. To formulate an effective asset allocation strategy, it is important to understand extreme events – both positive (booms) and negative (crashes) – and their effects on...

We show that adjustment cost models with labor supply can explain both asset returns and business cycle facts when adjustment costs penalize the changes of investment. This conclusion stands in contrast to results obtained in the literature with adjustment costs that penalize the changes of capital.

This paper examines the degree of persistence in the volatility of financial time series using a Long Memory Stochastic Volatility (LMSV) model. Specifically, it employs a Gaussian semiparametric (or local Whittle) estimator of the memory parameter, based on the frequency domain, proposed by...

This paper investigates the fractal behaviour of the electric spot prices traded in some European markets. Whereas the analysis leads to exclude the presence of multifractality, we provide evidence supporting the conclusion that the multifractional Brownian motion can represent a good candidate...

Health care costs represent a large and growing component of business and consumer expenditures in the US. Medical inflation represents these costs, and it differs from aggregate inflation and other market factors with respect to its rate of growth, statistical properties and the extent to which...

We present a novel asset pricing model that captures the investment wisdom and stock-selection approach of the long-term value-investors Benjamin Graham and Warren Buffett. Taking a longer term view of business prospects and business risks, we explicitly consider the time period in which a...
