10. Historically, Fannie Mae and Freddie Mac went to banks and other mortgage originators, firms that loaned money to homebuyers, and buy their mortgages. This allowed the banks and other originators to make still more mortgage loans. Fannie and Freddie and investment banks would combine mortgages and sell them to individuals and businesses in the form of mortgage-backed securities (MBS).

In financial investing, there is generally a tradeoff between risk and reward. Greater returns usually come with greater risks. Financial investors interested in investing in the U.S. housing market while prices were still rising, sometimes at double-digit annual rates (“Flip This House”), became interested in U.S. mortgage-backed securities issued by Fannie and Freddie and major investment banks

a. How did private markets evaluate the default risk of MBS and why were risks so underpriced prior to the 2007-09 recession?

b. Conservative investors in MBS could buy a form of “insurance,” from other firms including traditional insurance companies (AIG) called credit default swaps, against potential mortgage defaults. When MBS became toxic assets, what happened in the market for these insurance-like contracts?

After you graduate from university, you find a job in a company that produces good X. You are working in a competitive market. Your boss asks you to compute the price elasticity of demand, income elasticity of demand, cross-price elasticity of demand, and the price elasticity of supply. The question is: how your boss will benefit from computing each of these elasticities. Explain in detail with an example for each case.

2) Two types of customers make up the market for Armoyas. There are 100 type A customers, each of whom is willing to pay up to $10 for an Armoya. There are 50 type B customers, each willing to pay up to $8 for an Armoya. No customer wishes to buy more than a single Armoya. The monopolist cannot differentiate between the types of customer. The average and marginal cost of production is constant at $6/Armoya.

a) What is the selling price of the good, and how much profit does the monopolist make?

b) The monopolist is offered the opportunity to advertise Armoyas at a cost of $80. The advertisement is predicted to attract another 100 type B customers. Will the advertisement be placed? What is the selling price of the good, and how much profit does the monopolist make?

c) Suppose the advertisement attracts no new customers, but raises the price all existing customers are willing to pay by $1. Will the advertisement be placed? What is the selling price of the good, and how much profit does the monopolist make?

Suppose that the annual market demand for Bleebs is given by Q=3750-75P The average and marginal costs of producing Bleebs are $10/bleeb.

A) If the firm acts as a single-price monopoly, what are the monopoly quantity, price, and profit?

B) Suppose that there are three hundred identical customers in this market. What is the best two-part tariff that the monopolist can use? If the monopolist implements the two-part tariff, how much profit will it make?

C) It turns out that the monopolist was wrong about the makeup of the customers. At any price, 1/3 of the customers buy twice as much as the other two thirds. If the monopolist implements the two-part tariff in part b, how much profit will it make?

Switzerland, a country with a special status outside the EU, banned the imports of agricultural products linked with the usage of specific pesticides and implemented restrictive policies for crops derived from agricultural productions that use any kind of chemical and natural product, which is not related to the protection of the environment, food safety or health. a) Explain the factors that have brought Switzerland to implement such restrictions, commenting on this trade policy approach. (10 points) b) Now suppose that Switzerland gives its agricultural industry an unfair advantage through underpriced loans and other export subsidies.
