From the abstract:
Using the case study of Oklahoma and a recently developed econometric technique, we examine the impact of right-to-work (RTW) laws on state-level labor market outcomes. Our results show that the passage of RTW laws in Oklahoma decreased private sector unionization rates. Several other state outcomes including total employment rate and private sector average wages, on the other hand, were not affected by RTW laws. The findings for the private sector generally carry over to the manufacturing sector.
