Jane is the General Manager at a new caf and wants to hire a few baristas.The going rate for baristas is $15 per hour.Jane has heard that many of the local coffee shops have high turnover with baristas "ghosting" them - simply not showing up for their shifts and never coming back.Jane starts to put together an advertisement to hire baristas for $15 per hour, but changes her mind and lists the wages she will pay at $20 per hour.Why would Jane pay $15 per hour?What's her rationale for paying $20 (or any wage higher than $15)?
