This study estimates liquidity premiums using the recently developed Liu (2006) measure within a multifactor capital asset pricing model (CAPM) including size premiums and a time varying parameter model for the West African emerging markets of Nigeria. The evidence suggests that additional size and liquidity factors impart negligible impact in explaining the cross section of stock returns in the Nigerian domestic equity market. Costs of equity estimates are high further underlining the limitations of this market as a capital-raising venue in contrast to the dominant banking sector.
