My main areas of research focus on development finance and financial integration. I'm also interested in the complementarity between formal and informal finance such as the Rotating Credit and Savings Association. My research also examine the link between digital finance especially mobile money and financial account as well as the effects of financial innovation on childhood education.

Are mobile money and financial accounts complementary? Evidence from the WAEMU region, with Issouf Soumaré (January 2021)
Recently, the innovation of mobile money has experienced strong development and has been a key tool for financial inclusion in sub-Saharan Africa, including the West African Economic and Monetary Union (WAEMU). Even holders of formal financial accounts have adopted it widely. Based on a sample of 6,891 households in the WAEMU region, we study the complementarity between the use of mobile money and financial accounts. Our empirical results show that households generally perceive mobile money and the financial account as substitutes. We also found that the individuals for whom the two accounts are complementary have a high level of education and live in countries where formal and mobile financial services are more accessible. Moreover, contrary to anterior works, we show that among those for which the two accounts are complementary, almost 50% find that formal financial account is the complement. We attribute this preference to a very low use of formal financial services such as savings and borrowings in WAEMU.
