Discrete time volatility models typically employ a latent scale factor to represent volatility. High frequency data may be used to construct proxies for these scale factors. Examples are the intraday high-low range and the realized volatility. This paper develops a method for ranking and...

This paper investigates the impact of a Japanese fishery’s MSC certification on the related seafood markets. In September 2008, the Marine Stewardship Council (MSC) certified the Kyoto flat-head flounder Danish seine fishery (KDSFF) as the first sustainable fishery in Asia. Assuming the MSC...

This paper deals with testing a time series with a structural break in its mean for a unit root when the break date is known. A nonlinear (with respect to coefficients) test equation is used, providing asymptotically efficient estimates. Finite-sample and quasi-asymptotic empirical distributions...

The economic literature examining changes in divorce rates is not conclusive since legal reforms have been found to have permanent, transitory or no effect on divorce rates. This paper studies differences in divorce rates among 16 European countries from 1930 to 2006, by exploiting time-series...

The purpose of this paper is to examine the unit root properties of eleven Pakistani macroeconomic series using annual data. Along with traditional unit root tests, we use the procedure developed by Zivot and Andrews to test the null of unit root against the break-stationary alternative....

This paper explores the response of the divorce rate to law reform introducing unilateral divorce after controlling for law reforms concerning the aftermath of divorce, which are omitted from most previous works. We introduce two main policy changes that have swept the U.S. since the late 1970s;...

The purpose of this paper is to examine the relationship between domestic debt dynamics and fiscal deficits over the period 1970-2006. We pretest the variables for stationarity by carrying out unit root tests. However, a variable may appear to exhibit non-stationary behavior when in actual fact...

This paper examines whether stock prices for 16 countries are trend stationary or follow a random walk process using the (Zivot and Andrews, 1992) and (Lumsdaine and Papell, 1997) tests and monthly data (1987:12-2005:12). With one structural break, the ZA test results provide evidence in favour...

The Zivot and Andrews (1992) one-break and Lumsdaine and Papell (1997) two-break unit root tests are used to investigate the random walk hypothesis in Thai stock prices for the period December 1987 to December 2005. The results provide strong evidence that the Thai stock prices are characterized...

The ability of the economy to create jobs through economic growth, it is essential to improve social welfare. It has been argued that the persistence of unemployment in Chile post Asian crisis was mainly due to two factors: First, to a loss of employment generating capacity, expressed in a fall...
