Also, suppose the supply schedule can be represented by the equation Q8=200+ 10P, where QS is the quantity supplied. Refer to Scenario 4-1. Suppose the price is currently equal to 10 in this market. Is there a shortage or surplus in this market, and how large is the shortage/surplus?arrow_forwardYou own Earthworm Excavators. Your company is the sole manufacturer of super-sized excavators that are used in the world’s largest mining operations. The U.S. has recently lifted export restrictions on the product you sell, so you can now sell your equipment in the world market along with sales in the domestic market. You hire an economist to estimate the following (inverse) demand curves per year for these distinct markets: Domestic market : Pd = $1200 - $10QdForeign market : Pf = $600 - $5Qf where P refers to prices charged in each market in thousands of dollars and Q refers to the annual quantities demanded in each market. The total costs (in thousands of dollars) of your annual operation are given by: TC = 900 + 200Q a. If you decide to offer you machines at a single price to all potential buyers, at what price will the foreign buyers be priced out of the market?b.

- Consider the market for pork illustrated in the graph. Suppose initial demand (D') is Q = 290 – 20p and supply (S') is Q = 80 + 40p and that a $3.00 tax is charged to consumers, shifting the demand curve to D. Using the original and after-tax pork demand functions and the supply function, derive the initial equilibrium price and quantity and the after-tax equilibrium price and quantity. %24 (Enter all responses using real numbers rounded to two decimal places) The equilibrium price is initially $ per kg.

Suppose that the supply for recycled copper is Sr = 15+2.5q. Demand for copper is P = 65 - 1.5q. Note, buyers don't distinguish between recycled and virgin copper. The equilibrium price and output for copper is (hint: draw a graph) q=8.46, p = $52.31. q=0, p = $65. q=12.50, p = $46.25.

- The coconut oil demand function (Bushena and Perloff, 1991) is Q=1,200-9.5p+16.2pp +0.2Y, where Q is the quantity of coconut oil demanded in thousands of metric tons per year, p is the price of coconut oil in cents per pound, pp is the price of palm oil in cents per pound, and Y is the income of consumers. Assume that p is initially 50 cents per pound, pp is 29 cents per pound, and Q is 1,325 thousand metric tons per year. Calculate the price elasticity of demand for coconut oil and the cross-price elasticity of demand (with respect to the price of palm oil).
