Abstract

                  The study extends the popular duration dependence test and applies it to test for rational, speculative bubbles in Thailand’s stock market.

The extension is important because it allows duration dependence to be non-monotone and be able to vary with the levels of bubbles as well as economic

and financial variables. A non-monotone, time-varying duration dependence specification is new and made possible by applying a Cox proportional hazard

function together with a Generalized-Weibull baseline function. Using the SET index return data, the study finds that rational speculative bubbles exist in

Thailand’s stock market. The duration dependence is monotone decreasing and varies with the levels of bubbles and other economic and financial

variables such as bank loans, money supply and capital inflows.
