This paper generalizes the ACD models of Engle and Russell (1998) using the so-called q-Weibull distribution as the conditional distribution. The new specification allows the hazard function to be non-monotonic. We document that the q-Weibull distribution recently suggested in physics as a...

There is a big controversy among both investment professionals and academics regarding the question of how the probability that a bull or bear market terminates depends on its age. Using more than two centuries of data on the broad US stock market index, in this paper we revisit the duration...

We re-examine the presence of rational speculative bubbles in the Singaporean and Indonesian stock markets in light of contradictory results in the literature. We employ a mix of descriptive statistics, explosiveness tests and duration dependence tests for an expanded dataset from 1970 to 2013...

We scrutinize China, Hong Kong, Indonesia, Japan, Malaysia, Philippines, South Korea, Taiwan, and Thailand for the presence of rational bubbles by employing several tests on a large dataset that includes three bubble episodes. We also convert most tests into recursive to overcome structural...

Theoretical credit risk models a la Merton (1974) predict a non-linear negative link between a firm's default likelihood and asset value. This motivates us to propose a flexible empirical Markov-switching bivariate copula that allows for distinct time-varying dependence between credit default...

Consider using the simple moving average (MA) rule of Gartley (1935) to determine when to buy stocks, and when to sell them and switch to the risk-free rate. In comparison, how might the performance be affected if the frequency is changed to the use of MA calculations? The empirical results show...

Purpose: The purpose of this paper is to re-examine the presence of rational speculative bubbles in the Malaysian stock market in light of contradictory results presented in previous studies. Design/methodology/approach: We use descriptive statistics, explosiveness tests and the duration...

We consider trading against a hedge fund or large trader that must liquidate a large position in a risky asset if the market price of the asset crosses a certain threshold. Liquidation occurs in a disorderly manner and negatively impacts the market price of the asset. We consider the perspective...

This paper tries to identify, for the first time, a chronology for the Portuguese stock market cycle and test for the presence of duration dependence in bull and bear markets. A duration dependent Markov-switching model is estimated over monthly growth rates of the Portuguese Stock Index for the...
