Long Run Equilibrium (A) Firm and Industry: A competitive market is made up of a large number of firms with complete freedom of entry. Such firms together are called competitive industry. An industry can be defined as a group of firms producing homogeneous products with freedom of entry and exit and which earn only normal profits. Hence the concept of an industry is applicable only under competitive conditions. There is no fixed size of an industry though the analytical stability of an industry

LONG-RUN EQUILIBRIUM OF A FIRM UNDER PERFECT COMPETITION In the long run‚ a firm in the perfectly competitive market can earn only normal profit. So‚ the profit maximization under long run is: (1)Necessary condition P=LMR=LAR=LMC=LAC (2)Sufficient condition Slope of MC > Slope of MR We can establish this condition from the following analysis. In the above diagram for any market price OP1 the existing firms can earn supernormal profit as for the equilibrium output level OQ1. The average

Task 1: Draw in a graph the short-run supply curve of a single firm. Express as a function of Q the ATC and FR-ATC curve and draw them in a separate graph. Compute the minimum level of the ATC and FR-ATC curves and represent them graphically. Task 2: Suppose that the industry consists of 10 firms with cost curves given by those in Table 1. Find the short-run equilibrium price when the market consists of these 10 firms. (You should assume that these 10 firms act as price takers.) Task 3: Assume that

Equilibrium of the Industry: Short-Run and Long-Run Equilibrium! Since the price of a product under perfect competition is determined by the intersection of the demand and supply curves of the product of an industry‚ we need to know the nature and shape of the supply curve of a product under perfect competition. We shall now explain how the supply curve of a product under condition of perfect competition is derived and the shape it takes both in the short run and the long run. Before explaining

avoid the possibility of price war. The price charged by Title King is $ 20‚000. Ajax has the following short-run cost curve: TC = 800‚000 - 5‚000Q + 100Q^2 a) Compute the marginal cost curve for Ajax answer: Marginal Cost (MC) = dTC/dQ Since the derivative of a constant = 0‚ MC = -5‚000 + 200Q b) Given Ajax pricing strategy‚ what is the marginal revenue function for Ajax? Since Ajax is pricing as if it were a perfectly competitive firm‚ then‚ it’s price would equal its marginal

Using aggregate demand‚ short-run aggregate supply and long-run aggregate supply curves‚ explain the process by which each of the following economic events will move the economy from one long-run macroeconomic equilibrium to another. Illustrate with diagrams. In each case‚ what are the short-run and long-run effects on the aggregate price level and aggregate output? a. There is a decrease in households’ wealth due to a decline

A2 Markets & Market Systems Short Run and Long Run Production | | As part of our introduction to the theory of the firm‚ we first consider the nature of production of different goods and services in the short and long run. The concept of a production functionThe production function is a mathematical expression which relates the quantity of factor inputs to the quantity of outputs that result. We make use of three measures of production / productivity. * Total product is simply the total

into outputs by firms in order to earn profit. Production can be divided into two types‚ that is short-run production and long-run production. Production in the short-run is the production period of time over which at least one factor is fixed as production in the long-run is the production period of time long enough for all factors to be varied. As mentioned by Sloman‚ (2004)‚ production in the short-run is subject to diminishing returns. The law of diminishing (marginal) return applies whereby there

Micro Economic Exam Long Run versus Short Run 1. Introduction Competitive market equilibrium is the traditional concept of economic equilibrium‚ appropriate for the analysis of commodity markets with flexible prices and many traders. It relies crucially on the assumption of a competitive environment where each trader decides upon a quantity that is so small compared to the total quantity traded in the market that their individual transactions have no influence on the prices. This paper will

QUESTION 1 Price ceiling create shortage. How to overcome it? According to the book “Economic Theory in the Malaysian Context”‚ the definition of price ceiling is a legally established maximum price a seller can charge. It means that the price is lower than the equilibrium market price and it cannot go above the ceiling price. The reason that government imposes ceiling price on item such as beef‚ flour‚ sugar and many more is because to ensure that consumers are able to buy these goods at
