Review Demand and supply have been generalized to explain macroeconomic variables in a market economy. The Aggregate Demand-Aggregate Supply model is the most direct application of supply and demand to macroeconomics. Compared to microeconomic uses of demand and supply‚ different theoretical considerations apply to such macroeconomic counterparts as aggregate demand and aggregate supply. The AD-AS or Aggregate Demand-Aggregate Supply model is a macroeconomic model that explains price level and output

Part 1: Suppose that the tin mining market is perfectly competitive. The market demand curve is given by D(P) = 300 – P‚ where D is measured in units per year‚ and P is measured in $ per units. There are many potential entrants into this market‚ all of whom have identical cost curves. These cost curves are summarized in Table 1 below: Table 1 Cost Curve Formula Maginal cost (in $ per unit) MC = 30. Fixed cost per year FC = 100. (Annualized) Capital charge CC = 100. Capacity (in units per year)

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

States: * A deep recession hits the world economy. * The world oil price rises sharply. * U.S. businesses expect future profits to fall. a. Explain for each event whether it changes short-run aggregate supply‚ long-run aggregate supply‚ aggregate demand‚ or some combination of them. A deep recession in the world economy decreases aggregate demand. A sharp rise in oil prices decreases short-run aggregate supply. The expectation of lower future profits decreases investment and decreases

Given a certain event/scenario‚ (a) analyze the curve/s affected‚ shifts or movements and the direction‚ and (b) effect to equilibrium price (P*) and equilibrium quantity (Q*) Scenario 1 a. Prices of optical drives suddenly increase The production cost has increased so the supply decreases and eventually the price go up. The supply curve shifts to the left. b. A new market-standard

answer these questions: A. Which way should the equilibrium shift when HCl is added? How do your results support your answer? It should shift to the left because adding any component causes the equilibrium to shift to the opposite side. B. Which way should the equilibrium shift when Na2EDTA is added? How do your results support your answer? It should shift to the right because the removal of a component causes the equilibrium to shift to the side from which the component was removed

marketplace fluctuations in the supply and demand affect the price of the gasoline and everyone can see the result of that volatility at the pump as the gas price fluctuates accordingly. When demand for the gas is high retailers raise prices and when demand is low – the prices are driven down. As an example‚ one can observe that when in need for gas the intersection that has several gas stations would have the same or similar pricing for gas because the supply is high and the prices are contained by competition
