Abstract

A positive relation between risk and return is a fundamental tenet of finance. Despite the theoretical prediction of a positive time-series risk-return relation, empirical evidence is mixed, with studies finding evidence of positive, negative, or insignificant relations. Due to low test power, using small samples can result in negative or insignificant coefficient estimates on the conditional variance even when the true relation is positive. I pool data across 33 developed countries, covering almost 2,600 years of market returns, which provides the most comprehensive test of the time-series risk-return relation to date. The regressions with individual country returns yield insignificant results with few exceptions, highlighting the need for an expanded sample. Using the full sample of developed country returns, I confirm the fundamental prediction about risk and return. The estimated mean-variance coefficient is positive with strong statistical significance.
