One disadvantage of vector autoregressive (VAR) models is that they require time series to have equal lengths in the estimation process. This requirement induces a loss of potentially valuable information coming from time series that are longer than others. The issue is particularly evident in...

Hospital emergency departments are often overused by patients that do not really need urgent care. These admissions are one of the major factors contributing to hospital costs, which should not be allowed to compromise the response and effectiveness of the National Health Services (SNS). The aim...

Several studies have explored the linkage between non-performing loans and major macroeconomic indicators, using a wide variety of methodologies, sometimes with different results. This occurs, we argue, because these relationships are generally derived in terms of correlation coefficients...

Purpose - This article examines whether deviations from fundamental value or closed-end country fund's discounts or premiums forecast future share price returns or net asset returns. Design/methodology/approach - The main empirical (econometric) tool is a vector autoregressive (VAR) model. The...
