whether it changes the short-run aggregate supply‚ long-run aggregate supply‚ or a combination of the two‚ and why. a) Automotive firms in the United States switch to a new technology that raises productivity. Technological change enables firms to produce more from any given amount of facts of production. Therefore‚ technology increases potential GDP. So‚ an increase in potential GDP increases both- long run aggregate supply and short- run aggregate supply. b)Toyota and Honda build additional

CHAPTER 9 OLIGOPOLY AND FIRM ARCHITECTURE 1. The demand function for a product sold by an oligopolist is given below: QD = 370 – P The firm’s marginal cost function is given below: MC = 10 + 4Q Calculate the equilibrium price and quantity. Solution: P = 370 – Q so TR = 370Q – Q2 and MR = 370 – 2Q MR = 370 – 2Q = 10 + 4Q = MC so Q = 60 and P = 310 2. The demand function for a product sold by an oligopolist is given below: QD = 135 – 0.5P The firm’s marginal cost function is given

Introduction Aggregate demand is normally understood in the context of the total value of goods and services demanded by a given group of consumers at a given time period and at a given price (Brux 2007‚ p. 375).

Supply & Demand‚ and Price Elasticity All things in our society are connected in some way‚ for example‚ how humans relate to each other. Complex ideas and analysis are not without their own set of unique connections. The intricate theories of economics are a prime example of this connection. To gain an accurate understanding of how supply and demand are connected‚ and its role within the market‚ one must analyze the functions of each as separate entities‚ and how they relate to economics as a whole
