The Cafe Cash Register Standard
There is a cafe I like to visit whenever I am near Villanova University, where I studied and taught for many years. A few years ago, someone staged an informal experiment, putting a stamp on a dollar bill to make it easily identifiable. Staff at this cafe reported receiving the bill in payment no less than 30 times in a 60-day period. That one dollar bill became $30 in gross domestic product (GDP). In this sense, the local economy of the cafe is a phenomenally efficient engine of economic productivity.
