They find that this reform led to a reduction in the probability that a worker on a fixed-term contract would be converted to a permanent contract. In addition, those workers who had their contracts converted experienced a significantly higher hourly wage growth at the time of conversion and faced a lower reduction in wage growth during the years in which the changed legislation was in force. Consequently, the implementation of this law led to a 27% increase in the wage-growth differential between the two contracts. The findings are based on an endogenous regime-switching model using rich administrative linked employer\u2013employee data.<\/jats:p>","DOI":"10.1177\/0019793917737506","type":"journal-article","created":{"date-parts":[[2017,10,23]],"date-time":"2017-10-23T19:09:27Z","timestamp":1508785767000},"page":"760-788","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":12,"title":["Asymmetric Labor Market Reforms: Effects on Wage Growth and Conversion Probability of Fixed-Term Contracts"],"prefix":"10.1177","volume":"71","author":[{"given":"Marta","family":"Silva","sequence":"first","affiliation":[]},{"given":"Luis Filipe","family":"Martins","sequence":"additional","affiliation":[]},{"given":"Helena","family":"Lopes","sequence":"additional","affiliation":[{"name":"Marta Silva is a Research Economist at Banco de Portugal and is affiliated with the Business Research Unit (BRU-IUL) and the Centre for Socioeconomic and Territorial Studies (DIN\u00c2MIA\u2019CET-IUL).
