Some Observations on Minimum Wages

John Cochrane has a squeamish post service on minimum wages.

I was late discussing the theme of minimum payoff alongside a friend who favors them.  (He is a prominent economist, whose advert you lot would certainly recognize, but conversations alongside friends are off the record).  As justification for his view, he pointed me to this newspaper past times Lee in addition to Saez, called "Optimal minimum wage policy inward competitive undertaking market."

What was notable to me nigh this paper is the incredibly potent assumptions they necessitate to brand their case.  In particular,

Assumption 1. Efficient rationing: Workers who involuntarily lose their low-skilled jobs due to the minimum wage are those alongside the to the lowest degree surplus from working inward the low-skilled sector.

 Later they indicate out:

Finally, the desirability of the minimum wage hinges i time again crucially on the “efficient rationing” assumption. Under “uniform rationing”, where unemployment strikes independently of surplus, the minimum wage cannot amend upon the optimal taxation allocation, a indicate formally proven inward Lee in addition to Saez (2008). Indeed, alongside efficient rationing, a minimum wage effectively reveals the marginal workers to the government. Since costs of move are unobservable, this is valuable because it allows the authorities to kind workers into a to a greater extent than socially (albeit non privately) efficient ready of occupations, making the minimum wage desirable. In contrast, alongside uniform rationing, equally unemployment strikes randomly, a minimum wage does non give away anything nigh costs of work. As a result, it solely creates (privately) inefficient sorting across occupations without revealing anything of value to the government. It is non surprising that minimum payoff would non live on desirable inward this context.

Rather than providing a justification for minimum wages, the newspaper seems to produce but the opposite. It shows that you lot necessitate implausibly potent assumptions, such equally efficient rationing, to brand the case.  I cannot meet whatsoever compelling argue to believe that inward the presence of excess furnish of workers, the marketplace volition somehow cope to efficiently ration the scarce jobs.
