Identify which cost of inflation—menu costs or shoe-leather costs—is illustrated in each of the following scenarios.

a. During the German hyperinflation of 1922–1923, some workers reportedly were paid two to three times per day. They would then rush out to spend their earnings before they became nearly worthless.

b. A hyperinflation in Zimbabwe was so severe that, according to one observer of supermarket employees, they were “running around that store with label makers, changing the prices three, four times a day.”
