a) (3 points) Estimate how much it costs for Starbucks to make a cappuccino. (hint: think how much it would cost you if you would make it at home. However, take also into account that Starbucks must pay their baristas, pay for overhead expenses - this includes advertising, administrative (headquarters), depreciation, amortization, R&D, and all other expenses, such as income taxes and interest. (you can track the 2022 Starbucks annual report to get data for this), store rent in Irvine). Make sure you provide us all the data sources you used for your calculations. b) (1 point) Do you think Starbucks loses money when anyone sits at a table for over an hour? Justify your answer. c) (1 point) The profitability of Starbucks in 2018 in Europe was one-third of that in North America. Why do you think this is the case? d) (5 points) The marginal product of labor is a concept in economics that measures the increase in output as a result of adding one more unit of labor (worker). It provides an estimate of the additional amount of output that can be produced by adding one more worker to the production process. Use graphical analysis to discuss how the marginal product of labor may evolve as you keep hiring more workers on a Starbucks coffeeshop such as those we have at the UCI campus.
