We study whether segmented labor markets with flexibility at the margin (e.g., just affecting fixed-term employees) can achieve similar volatility than fully deregulated labor markets. Flexibility at the margin produces a gap in separation costs among matched workers that cause fixed-term...

This paper extends the standard matching model by introducing a gap in separation costs between entrant and incumbent workers. We show that when this gap is omitted from the model, these costs do not improve the labor market volatility without introducing unrealistic unemployment responses to...

This paper extends the Diamond-Mortensen-Pissarides (DMP) matching model with endogenous job destruction by introducing post-match labor turnover costs (PMLTC). We consider training and separation costs which create heterogeneity among workers. In particular, there are two types of employed...
