This paper uses a frequency domain approach to gain insight into the correlation between survey indicators and year … of the correlation between survey indicators and year-on-year GDP growth at the different frequencies to explain their … overall correlation. We show that survey indicators, similar to year-on-year GDP growth, do not perfectly reflect business …

A new test for constant correlation is proposed. Based on the bivariate Student-t distribution, this test is derived as … & Rouwenhorst, 2005) specify the unknown correlations as piecewise constant, our model-setup for the correlation coefficient is …

The paper proposes a new method to estimate correlation of account level Basle II Loss Given Default (LGD). The … correlation determines the probability distribution of portfolio level LGD in the context of a copula model which is used to … we apply the maximum likelihood method to estimate the best correlation parameter.
