Suppose the market for nurses can be modeled using supply and demand (the market is perfectly competitive). There are a large number of hospitals, doctors’ offices, clinics, etc., so that no individual employer has an impact on the market wage. The nurses are not unionized so they individually have no impact on the wage.
Demand is given as Qd = 24,000 – 320W, where Qd is the quantity demanded (in full-time equivalents) and W is the hourly wage rate.
Supply is given as Qs = -18,000 + 1250W, where Qs is the quantity supplied.
24,000 – 320W = -18,000 + 1250W
If, at this point, you have a negative wage or negative quantity, you’ve made an error and should start over.
Another way to solve the above problems would be to derive the ‘inverse demand curve’ and the ‘inverse supply curve.’ The inverse supply curve gives the wage as a function of the quantity supplied. Given the supply function above, the inverse supply function is:
W = 14.4 + 0.0008Qs
Be sure you can duplicate the above answer before moving on to 3.
3 and 4. Derive the inverse demand function. It should take the form W = a + bQd, where a and b are derived from the demand function’s parameters. You will report a as the answer to (3) and b as the answer to (4). b should be reported to 6 decimal places.
If you set the inverse demand function equal to the inverse supply function you can solve for the equilibrium quantity (while you have Qd and Qs in the equations, you can make use of the fact that, in equilibrium, Qd = Qs, so that you are simply solving for Q).
5. What is the wage rate using the above approach?

DEMAND & SUPPLY: Consider the market for bananas which is known to be perfectly competitive. The market is characterized by the following relationships: QD = 10,000 – 140P QS = 7500 + 125P Plot the demand curve and the supply curve on a graph. Clearly label the axes and the intercepts. Why is the demand-curve downward-sloping? What is the slope of the demand curve? Why is the supply-curve upward-sloping? What is the slope of the supply curve? What is the...
For Question 1-8, consider a competitive market for a good where the demand curve is determined by the demand function: P=5-QD and the supply curve is determined by the supply function: P=QS. Where P stands for Price, QD is quantity demanded and QS is quantity supplied. What is the equilibrium price level for the good in the competitive market?
1. The market for a product is defined by the following demand and supply curves: Qd=20-7p Qs=-4+5P where Qd and Qs are the quantities demanded and supplied, and P is the price of the product in £s. (i) Draw (accurately) a diagram to depict the market for this product and determine the equilibrium price and quantity. (ii) Solve for the equilibrium market price and quantity mathematically (remember that, in equilibrium, Qd=Qs).
