As developing and transition economies enter the next phase of reforms, labor market issues increasingly come to the fore. With the increased competition from globalization, the discussion is shifting to the need for greater labor market flexibility and the creation of "good" jobs. Moreover, the greater actual and perceived insecurity in labor markets has generated a new agenda on how to structure safety nets and labor market regulation. The older questions of the links between the formal and informal labor market, reappear with new dimensions and significance. More generally, it is clear that an accurate understanding of how labor market structures function is essential if we are to analyze alternative policy proposals in the wake of these concerns.
