CNBC reports that the burger chain Shake Shack is planning to trial a new restaurantin New York which will not have a traditional cashier’s counter. Instead, “guests will use digital kiosks or their mobile phones to place [and pay for] orders.” Their order will be processed immediately to the kitchen and the guest will receive a text message when their food is ready.
Great, you might think. Shake Shack is investing in innovations which could improve the productivity of remaining workers, increasing wages (indeed, they want to pay the lower relative number of staff in this restaurant at least $15 an hour). Such investments might provide a more efficient and desirable service to customers too. This frees resources and excess labor for other more productive pursuits in the economy.
But the kicker for why Shake Shack is undertaking such investments comes later in the article:
it’s likely that in the next 15 to 20 months that areas like New York, California and D.C., in which there are many Shake Shacks, will transition to a $15 minimum wage…Adopting this payment policy in Astor Place will give the company a chance to work out the kinks before it rolls out a $15 minimum wage in these locations.
Anyone who has been to a McDonald’s in France will know what’s going on here. Shake Shack suspects that the cost of labor will rise due to an increased minimum wage, and given that projection, it’s become economic to consider investments in labor-saving technologies. Higher minimum wages act in effect as a subsidy to automation.
