Explanation of Solution
In a domestic production market, the steel industry is an oligopoly because there are a small number of firms and the products are standardized. The size makes it difficult for new entries and there is non- price competition and no collusion.
Concept introduction:
Pure competition: Perfect competition refers to the market structure which features more number of sellers and buyers in the market and the firm can sell homogenous products.
Pure monopoly: Monopoly refers to the market structure with the features of a single seller and more buyers. Firms have full control over the market. Price is fixed by the monopoly producer. There is a restriction for entry of the firm. Hence, there are no substitute goods available in the market.
Monopolistic competition: Monopolistic competition refers to the market structure with the feature of more firms producing differentiated goods. These goods are called substitute goods: but they are not perfect substitutes. There is no restriction to enter the business. Firms are price makers.
Oligopoly: Oligopoly refers to the market structure which features few sellers and more buyers.

Explanation of Solution
Wheat farms are pure competition in the market because there are a number of similar farms and the products are standardized. Also, there is no control over the price and no non-price competition. Since the cost of acquiring land from a present proprietor is large, entry is difficult.

Explanation of Solution
Commercial banks are in a monopolistic competition because there are many similar banks, the services are differentiated, and there is price control mostly in interest. Entry in the market is easy and there is much advertisement. Not every bank fits in the description of the monopolistic market; some smaller places act as a monopoly or an oligopoly.

Explanation of Solution
Automobile industries are an oligopoly because there are three big automakers in a market, the products are differentiated, and their size makes it difficult for new entries. There is also a lot of non-price competition; it does not appear to have no collusion and there is little price competition. Thus, imports make the industry more competitive and reduce the market power of US automakers.

- Question Seven There are specific applications of the hidden-action or moral hazard model. Consider employment contracts signed between a firm's owners and a manager who runs the firm on behalf of the owners. The manager is offered an employment contract which they can accept and decide how much effort, e ≥ 0, to exert. Suppose that an increase in effort, e, increases the firm's gross profit, not including payments to the manager, but is personally costly to the manager and the firm's gross profit, Пg, takes the following form: Пg = e +ε, ε~N(0,2). Let s denote the salary, which may depend on effort and/or gross profit, depending on what the owner can observe, offered as part of the contract between the owner and manager. Suppose that the manager is risk averse and has a utility function with respect to salary of the form: Aσ² U(W)=μ- 2 a) Derive the optimal result of the owner's expected net profit where there is full information and state what it implies. b) Suppose now that the…arrow_forward1. The IS/MP model assumes that the Fed sets the real interest rate at a given level Rt. Suppose the Fed adopts a monetary policy rule that instructs it how to change the real interest rate in response to short-run output. Let's call this a monetary policy rule (MPR): The parameter x is positive. Rt=+xY a) Redraw the IS/MP diagram replacing the MP curve with the MPR curve. Show how an aggregate demand shock affects output and interest rates in the short run. Use the IS and MPR equations to solve for the changes in output and the real interest rate. b) How does the change in a affect investment in the IS/MPR model? Explain how a tax cut affects short-run output and investment in this version of the short-run model. The effect on investment is called crowding out. c) Add the Phillips curve to complete the short-run model.
