Examines the different employment structures in leisure and retail organizations in the light of the recent Sunday Trading Act, 1994. Considers the make‐up of staff; training methods; rates of pay and changing customer demand patterns in order to draw comparisons and identify possible emerging...

We study the ability of traditional diagnostic tests and LM and CUSUM structural break tests to detect a range of different types of breaks in GARCH models. We find that Wooldridge's (1990) robust LM tests for autocorrelation and ARCH have no power to detect structural breaks in GARCH models....

The San Vicente volcano in central El Salvador has a recurring and destructive pattern of landslides and debris flows occurring on the northern slopes of the volcano, and in recent memory, there have been at least seven major destructive debris flows. There has been no known attempt to study the...

We compare the ability of correlation and threshold effects in a stochastic volatility model to capture the asymmetric relationship between stock returns and volatility. The parameters are estimated using maximum likelihood based on the extended Kalman filter and uses numerical integration over...

Using a number of alternative approaches, Sichel (1994) demonstrated evidence supporting the notion that the US business cycle is best characterized as having three distinct phases, viz. contraction, followed by rapid expansion during the early stages of the recovery phase, followed by a period...
