Explain what changes in structural variables could lead to the smaller  quantities demanded and supplied while the equilibrium price stays at $4. Draw the relevant  supply-demand diagram, which furnishes the coordinates of the DD and SS curves, characterized  by the smaller quantities demanded and supplied at the $4 price.   Provide a detailed explanation of your diagram.

Suppose that the demand and supply curves for good X are: QD = 75 − 1.25P and QS = −60 + 2.50P  A: Algebraically solve for the market equilibrium price and quantity, neatly showing your work. B: Neatly construct a graph and plot the demand curve, carefully showing the horizontal andvertical intercepts. On the same graph, neatly plot the supply curve, showing an intercept. Label theequilibrium.

Question 3 Starting from an equilibrium point, explain the impact of an increase in the incomes of people in Qatar on the equilibrium price and equilibrium quantity of used cars (inferior good). Explain and illustrate your answer using the demand and supply model.

In the S-shaped model of the dynamics of house price booms and busts, a) A negative feedback process takes the housing market from the high to the low equilibrium. b) The high price equilibrium is sustained by a positive feedback process. c) The low price equilibrium is stable. + 4)

For each of the following changes, determine whether there will be a movement along the demand/supply curve or a shift in the demand/supply curve. If there is a shift in the curve, indicate the direction of the shift. • an increase in the price of a complement in production   • a decrease in tastes of consumers for a product   • a decrease in the number of buyers in the market   • a lowering of the product price   • a worsening of business expectations   • a decrease in government subsidies to firms

If the demand function for a commodity is given by the equation  p2 + 4q = 1200  and the supply function is given by the equation  700 − p2 + 10q = 0,  find the equilibrium quantity and equilibrium price. (Round your answers to two decimal places.)

Suppose there is an expectation of a rapid general price increase in goods and services in Australia in January 2021. Examine the effects of the anticipated general rapid increase in price for goods and services.

Consider a market in which the demand curve is given by P= 1000-50, and the supply curve is given by P=7.20. Suppose there is a positive supply shock and the supply curve shifts to the right, so that quantity supplied increases by 100 at each price. What is the new equilibrium price? Give your answer to 2 decimal places. 590.2

Equilibrium Scenarios On a separate piece of paper, use an appropriately labeled supply/demand graph to answer the following questions. For each question, you need to a) state the determinant of demand (TRIPE)/supply (NICEJAG) that caused the change, b) graph the change, and c) tell me what happens to equilibrium price and quantity. 1. What would be the effect of an increase in automobile worker wages on the market for automobiles? 2. What would be the effect of a decline in the price of personal computers on the market for software? 3. What would be the effect of an increase in the price of Budweiser beer on the market for Coors beer? 4. What would be the effect of a governmental subsidy on the market for AIDS research? 5. What would be the effect of a decline in the price of irrigation equipment on the market for corn? 6. What would be the effect of the government subsidizing the growers of watermelons on the market for watermelons? 7. What would be the effect on the market for Big…

Suppose there is a positive supply shock and the supply curve shifts to the right, so that quantity supplied increases by 100 at each price. What is the new equilibrium price? Give your answer to 2 decimal places.
