We develop a new global asset pricing model to study how illiquidity interacts with market segmentation and investability constraints in 42 markets. Noninvestable stocks that can only be held by foreign investors earn higher expected returns compared to freely investable stocks due to limited risk sharing and higher illiquidity. In addition to the world market premium, on average, developed and emerging market noninvestables earn an annual unspanned local market risk premium of 1.17% and 9.04%, and a liquidity level premium of 1.06% and 2.39%, respectively. These results obtained in a conditional setup are robust to the choice of liquidity measure.

We propose an estimation methodology tailored for large unbalanced panels of individual stock returns to study the factor structure and expected returns in international stock markets. We show that the local market is necessary to capture the factor structure in both developed and emerging markets. Neither the presence of multiple world or regional risk factors, systematic currency risk factors, nor a country-specific currency subsumes the importance of the local market factor. All factors, including the local market, carry significant risk premia across a large proportion of countries. The contribution of pricing errors to total expected returns is large and time-varying.
