> Supply-and-demand theory once made sense. That was before employers gained so much power. Except power itself is determined by supply and demand. Employers have gained more power precisely because of the increased labor supply (more women, more robots, more foreign workers) that is also responsible for stagnant wages. The power, of course, comes from the need for others to have association with that person/business…
My summary of the article would be: If supply and demand were working, a minimum wage increase would cause a loss of jobs. We studies minimum wage increases and jobs were not loss. The conclusion was therefore that Supply and demand were broken. Then then want on to say how they found a link between having a small number of employers in a field and lower wages.
Which seems like a rather bizarre conclusion. Minimum wage is a form of supply management. You do not have to lose any jobs, but you have eliminated the competition, at least on factors of price, as it is illegal for someone else to do the job for less. With a smaller labor supply, effectively speaking, price is able to rise.
