The trend reflected in the job quality index constructed for this study indicates that economic growth alone is not enough to improve the quality of employment. Econometric techniques are used to estimate the long-run relationship between this index and GDP. The results of those calculations clearly point to a negative relationship between these two variables from 2005 on, when job quality began to improve against a backdrop of strong economic growth in combination with changes in the institutional framework (labour laws and collective bargaining mechanisms) that were conducive to an improvement in job quality.
