Student name:__________

1) It is commonly believed that the best ways to motivate an employee are (1) to improve the quality of the workplace and (2) to make the employee feel like he/she is part of the company. How would an economist analyze these statements?

2) Stella Ann Freeman is having a difficult time deciding whether or not to purchase a new car. How would understanding the concept of opportunity cost help her make a decision?

3) Jim Range has to choose between buying more soda or more pasta for the week. He has a fixed income and he knows the prices of both products.

(b) In April, Patrick receives a 5 percent pay increase. Inflation raises the price of concerts to $10.50 and the price of Celtic Springs Water to $2.10. Draw Patrick's new budget constraint and optimal consumption bundle, considering that the number of Celtic concerts is measured along the horizontal axis. How many Celtic concerts does he attend in April? How many bottles of water does he drink in April?

5) Ali inherits $10,000 from his great-great aunt in 2018. His great-great aunt's will requires that Ali spend the money before December 31, 2019.
