In your report, there is a section about how program policies changed between 2002 and 2013. I will read what it says about that in English:
Furthermore, these policy changes occurred even though there was little empirical evidence of shortages in many occupations. As a result, controlling for different responses to shocks across provinces and other contemporaneous changes, I find that these modifications to the TFWP actually accelerated the rise in unemployment rates in Alberta and British Columbia.
In short, the way the policy was applied over at least the past 11 years had a direct impact on the labour market and on employment.
Can you comment further on that?
