Financial incentives and labour market duality

The French labour market is divided between workers in permanent jobs and those who alternate fixed-term contracts with unemployment spells. Among other public policies aiming at reducing this duality, financial incentives could induce employers to lengthen contract duration or favour permanent contracts. This article develops a matching model fitted to the French labour market characteristics and calibrated on French data. A gradual decrease in unemployment contributions or a firing tax reduces the share of short-term contract in total employment but increases market rigidity and lowers labour productivity. However, decreasing unemployment contributions gradually is less favourable for new entrants than a firing tax and lengthens unemployment spells. An additional contribution levied on short-term contracts to finance a bonus for permanent-contract hirings also decreases labour market duality and increases activity by 0.13% but without negative impacts on labour market flexibility and productivity.
