Do employees benefit from worker representation on corporate boards?

In the RD sample, firm size refers to the number of employees in the firm, measured in January of the year before the year in which we measure worker representation status and wages. [...] The third subsample, which we refer to as the RD sample, restricts the full sample to workers employed by firms in a window of 20 employees on either side of the firm size discontinuity in the rights to representation, which occurs at 30 employees.4 The final subsample, which we refer to as the adoption sample, restricts to workers employed by a firm adopting worker representation for the first ti. [...] The last set of bars also controls for the average age of workers in the firm, the immigrant share, the share of workers that are male, the share of workers that are unionized, and the share of high-skilled workers. [...] If this were the case, we would expect the wage growth of workers in the treatment group to be lower than that of the comparison group in the years before the move. [...] While the unrestricted means show the underlying variation in the data, we also plot estimated local linear regression lines on each side of the firm size cut-off, to illustrate the trends in the data and the sizes of the discontinuities at the cut-off.
