In 2013, France’s labor unions won a case against Sephora to prevent the retailer from staying open late and forcing its workers to work “antisocial hours.” The cosmetics store does about 20% of its business after 9 P.M., and the 50 sales staff who work the late shift are paid an hourly rate that is 25% higher than the day shift. Many of them were students or part-time workers, who were put out of work by these new laws. Identify the inefficiency and figure out a way to profit from it.

The quality of the good produced by half of theproducers (type L) is low, and the quality of the good produced by theremaining half (type H) is high. Each producer knows the quality of hisoutput and has no production cost.The market contains also traders, each of whom can buy a unit of thegood from a producer. If a trader buy a unit, he can sell it for the price20 if it is high quality and for the price 10 if it is low quality. No tradercan verify the quality of a good prior to purchasing it.A producer can obtain a certificate that says that his output has highquality. The cost of such a certificate is 4 for type H and 12 for type 12for type L. (A type L producer has to bribe the agency who gives thecertificate.)Traders make offers.
