Are global systematic risk and country-specific idiosyncratic risk priced in the integrated world markets?

摘要

Empirical evidence showing significant effects of local factors on international equity returns while failing to find significant effects from global systematic risk seems counter-intuitive in today's integrated world markets. This paper uses the conditional second moments estimated from an asymmetric dynamic conditional correlation model to measure the time-varying world beta and country-specific idiosyncratic risks, and tests the relationship between country-level index returns and world beta risk conditioned on positive and negative world market returns. The results show that the conditional dynamic world beta risks significantly predict the cross-country variation in expected index returns, while country-specific risk is not significantly priced.
