The aim of this paper is to study the relationship between earnings management and the liquidity of the Tunisian market. Our study was conducted on a sample of 19 companies listed on the Tunis Stock Exchange over the 1999 - 2011 periods. Our results corroborate the existence of a positive and significant relationship between the earnings’ management achieved by the Tunisian companies and the market liquidity. Our study shows that the practice of earnings’ management makes the market more liquid. This result can be accounted for by the lack of awareness among the liquidity- providers of this practice, especially as the level of earnings’ management and the level of disclosure carried out the by companies that constitute our sample are not very high. Besides, this result confirms the theory stating that the investors buy the earnings.
