Abstract

This study contrasts well established liquidity measures, namely volume-based turnover ratio, related price-impact Amihud (2002) construct and the multidimensional Liu (2006) indicator alongside the Lesmond, Ogden, and Trzcinka (1999) proportion of zero daily returns metric in explaining bid-ask spread plus commissions costs. We control for six critical firm governance characteristics that impact liquidity alongside the market-based controls that are conventionally solely included in the literature. Using a unique sample of 12 Sub Saharan African (SSA) equity markets, namely Kenya, Mauritius, Zambia, Zimbabwe, Botswana, Malawi, Namibia, Nigeria, Ghana, BRVM (Cote d'Ivoire), and then South Africa's ALT-x and Main boards we find evidence that state and foreign venture capitalist involvement in firms enhances liquidity while involvement of foreign partners, entrepreneurial founders, domestic venture capital and inclusion within an extended business or family network has opposite effect. The evidence supports the use of the proportion of daily zero returns measure in preference to other measures in capturing illiquidity. Furthermore we find that liquidity is closely associated with three of six World Bank Governance measures of institutional quality with these being government effectiveness, regulatory quality and rule of law.
