Froeb discussed post-investment holdup as a sunk cost problem associated with contract-specific fixed investments. The modern theory of contracts is sometimes called the theory of joining wills, which simply means when parties make an agreement they are joining together to endeavor of mutual interest. The problem with all contracts that endure over time is that not all potential challenges can be anticipated. attempt to seek accommodations to advance

their mutual interest, so long as the return on the invested activity pays off. Froeb illustrates the idea by the example of marriage as a contract (1).

1. Your firm conducted a search for a new chief financial officer and hired a highly qualified candidate with a yearly salary of $250,000. After six months, the person left to join another firm.
2. Your firm has an exclusive contract to assemble automobile seats for a number of luxury models. Almost 100% of the materials are imported and, of those, over 50% include parts manufactured in China. All of the prices on the parts from China increased by 25% when the U.S. imposed tariffs on China. Your company has informed all of its customers that increased cost must be passed on for your firm to continue supplying the seats. All of your customers reluctantly agreed to pay the additional cost.
3. Your company took note of your progress toward your MBA, and when the director for customer services left the company, you were asked to take over as interim director. You were encouraged to apply for the full-time position once you got your MBA. You served for 13 months, at which time your company was acquired by another company and your position was abolished.

There was a contract in place between the seat makers and the auto makers.The seats werea highly specific and unique product..So is the automanufacturer'sdemand curve for seats highly elastic or highly inelastic?
