A test for structural break based on quantile regressions (QR) reveals the impact of a break in the tails of the …. By repeatedly computing the QR test it is possible to check for stability of the coefficients both over time and with …

the paper presents a Lagrange multiplier test for structural break. The advantage of the LM test is in the ease of … implementation, since it simply requires the estimation of an auxiliary regression. An example shows the characteristics of each test …

The link between low levels of central bank independence (CBI) and high levels of inflation has long been established …

In a recent paper, Wilson (2003) investigates a number of independence tests and finds that they … as heteroscedasticity, so that the test can be used to test for (full) independence when the efficiency distribution has … and (iii) obtaining aggregate measures of industry efficiency. We propose a semi-parametric Hausmann-type asymptotic test …
