The demand for scarves depends on the weather during winter. If it is a heavy winter, then the demand for scarves is QH (P) = 84-3P and if it is a light winter the demand for scarves is QL(P) = 85-4P. The supply of scarves is Qs(P) = 4P - 7. a) Find the equilibrium price and quantity in each case. b) Calculate the elasticity of demand and the elasticity of supply when P = 10. Comment on your results. c) In separate graphs, draw the two cases and depict the consumer and producer surplus. Calculate the surpluses in all cases. d) The government wants to limit the production of scarves and sets a quota of 42 scarves. What is the effect of the quota in each case? In separate graphs, draw the effect of the quota. Calculate the effect of the quota on welfare (consumer surplus etc).

The price elasticity of supply for basmati rice (an aromatic strain of rice) is likely to be which of the following? multiple choice Higher in the long run than the short run, because farmers cannot easily change their decisions about how much basmati rice to plant once the current crop has been planted. Low in both the long and short runs, because rice farming requires only unskilled labor. High in both the long run and the short run, because the inputs required to produce basmati rice can easily be duplicated. High, because consumers have a lot of other kinds of rice and other staple foods to choose from.

For problems 1 – 4: The Dolan Corporation, a maker of small engines, determines that in 2019 the demand curve for its product is P = 2,000 - 50Q where P is the price (in dollars) of an engine and Q is the number of engines sold per month. What is the price elasticity of demand if price equals $750? a.-0.6 b.-1.667 c.-0.02 d.-1.00

You are an economist for the City Subway Commission. Presently, the price of a subway ride is 80 cents, and 250000 seats are filled weekly. The price elasticity of demand for subway rides is -0.40, and the income elasticity of demand is -0.60. (A) If a recession lowered area incomes by 5%, how many additional seats per week would the subway need?

The demand for hair dryers is described by the following function: P= 240-5Qd If the price is $185, what is the quantity demanded? If the price is $185, what is the total revenue? If the price is $175, what is the quantity demanded? If the price is $175, what is total revenue? Compute the price elasticity of demand at the average price of $180.

An entrepreneur's most recent venture is selling robots that he builds and programs himself. At a price of $160 each, he sells 660 robots. At a price of $290 each, he sells 340 robots. What is the price elasticity of demand for his robots? Present your elasticity using its absolute value.

p = 3 +0.5Q s What is the elasticity of supply? (P=10, Q=14)

Suppose the demand for a product is given by D(p)=-8p+227. A) Calculate the elasticity of demand at a price of $18. Elasticity = (Round to three decimal places.) B) At what price do you have unit elasticity? (Round your answer to the nearest penny.) Price = $

Problem Number 8 Economics: Elasticity of Demand for DVD Rentals. The demand for DVD rentals at Klix Video is given by q= D(x) = 120 - 20x, where q is the number of DVDs rented per day at x dollars per rental. Find each of the following. a) The elasticity as a function of x b) The elasticity at x = 2 and at x = c) The value of x for which E(x) = 1. Interpret the meaning of this price. d) The total-revenue function, R(x) = (x) D(x) e) The price x at which total revenue is a maximum 4. Interpret the meaning of these values of the elasticity.

The demand and supply for cola in a market is represented by    QD = 15 – 10P   &    QS = 40P – 50 Calculate the point price elasticity of demand at the equilibrium
