This paper uses time-varying second moments to investigate exchange rate exposure betas. Using a BEKK-GARCH(1,21)-M model, time-varying exchange rate exposure betas are obtained with explicit focus on the non-orthogonality between exchange rate changes and market returns. We look into certain...

This paper examines the adequacy of the exposure coefficient/beta in measuring the entire impact of exchange rate changes on firms' future operating cash flows. To this end, we investigate the presence of four elements of exchange rate exposure: (a) sensitivity of stock returns to exchange rate...

On the basis that the sources of sign and magnitude asymmetries of exchange rate exposure are largely related to each other, this paper attempts to capture both types of exposure asymmetries in tandem. In addition, the overall impact of incorporating exposure asymmetries on returns is also...

The study examines the behavior of stock returns and volatility of returns in CSE around both Presidential and Parliamentary elections. Based on daily data during the sample period January 1985 through September 2009, a univariate GARCH model with return and volatility dummies is employed for...

This study examines the impact of terrorism on stock returns and volatility from an econometric perspective. Taking daily returns within the sample period May 1985-January 2007, the relevant hypotheses are tested in the context of the Colombo Stock Exchange. A GARCH specification is used to...

This study examines the existence, magnitude and direction of volatility spillovers between the Sri Lankan stock market and two other major stock markets in the South Asian region: India and Pakistan. Main stock indices of Sri Lanka, India, and Pakistan are employed as proxies to represent stock...

The Heteroskedastic Mixture Model (HMM) of Lamoureux, and Lastrapes (1990) is extended, relaxing the restriction imposed on the mean i.e. μ_t-1=0 . Instead, an exogenous variable r_m, along with its vector β_m, that predicts return r_t is introduced to examine the hypothesis that the volume is a...

The objective of this study is to identify the short- and long-run determinants of inflation in Sri Lanka. It follows an eclectic approach to seeking possible determinants of inflation and employs an Autoregressive Distributed Lag (ARDL) bounds testing approach to test for co integration between...
