This study proposes a new approach to the estimation of daily volatility in financial markets. To do this we evaluate a number of traditional estimators of daily volatility based upon intra-day data and propose a new estimator of daily volatility based upon intra-day data which is both unbiased...

Testing for linearity in time series models has been an active area of research [see Granger and Terasvirta (1993), Tong (1991)]. The authors consider a test for linearity against a particular regime switching model known as the smooth transition autoregressive (STAR) model.

This paper investigates whether the systematic asymmetric behaviour of the US unemployment rate can be explained by the stock market. We consider threshold models to capture the asymmetric relationship between quarterly US unemployment rate and Dow Jones Industrial Average (DJ) stock returns. We...

This paper investigates whether or not the LM techniques proposed to test the null hypothesis of linearity against GARCH, bilinear (BL) and Joint GARCH-BL alternatives separately, have desirable finite sample properties. The result of a Monte carlo simulation study show that their sizes are...

This paper investigates the short- and long-run Indonesian regional labour market integration using Johansen's system approach. The authors have tested for a number of co integrating relationships and common trends among West-Java, East-Java, Central-Java and Jakarta, wage rates, and for the...
