Collective bargaining is an important instrument to deal with old and new challenges in the labour market, such as facilitating technological transitions or preventing inequalities in the labour market. This paper discusses the economic effects of collective bargaining systems and the importance of their design drawing on a mix of macro and micro evidence. It also provides a benchmarking exercise to compare the Chilean bargaining system with those of other OECD countries. Finally, it discusses noteworthy practices in other countries that can offer valuable insights to Chile as it contemplates the introduction of sectoral bargaining models.
