La profitabilité des secteurs de l’économie sénégalaise

This paper focuses on performance measures based on a panel of 22 sectors of the Senegalese economy. A particular emphasis is made on the profitability which is the indicator looked at by both the government to identify sectors that need help, investors to know which sector is attractive and also banks who need to appreciate the level of risk of a sector. Markov Chains test was conducted to check the persistence of profitability among sectors. The findings revealed the absence of convergence of sectors. Technical inefficiency has been therefore included to explain the profitability discrepancies found between sectors measured by the fixed effects. The profit loss due to inefficiency is also computed for each sector.
