The gig economy is a rapidly growing portion of the US labor landscape. It is appealing to many individuals, as it provides autonomy for workers and opens up increased opportunities for working jobs with desirable schedules. The new California legislation, Assembly Bill 5, is likely to disrupt this sector by increasing costs for employers and removing autonomy from independent contractors with the ABC test that challenges current legal classifications of independent contractors. The ABC test has previously been passed in Massachusetts in 2004 and this paper aims to determine how the test has impacted the Massachusetts self-employment sector. A difference-in-differences estimation and linear regression model were analyzed to accurately determine the impact. A minimal negative correlation was found between the introduction of the ABC test in Massachusetts and the proportion of self-employed individuals in Massachusetts post-treatment. It was also found that the percentage change of average wages for self-employed individuals sharply increased in the first year directly following the implementation of the ABC test in Massachusetts and then decreased in the next year. The regression showed little correlation between the ABC test and self-employment in Massachusetts, as the p-value was not significant at the 5% level for the difference-in-differences interaction term, possibly due to limitations of the model.
