A commercial airline is analyzing the price scale for round trip flights between New York and Pennsylvania. The sooner the customer buys the ticket, the cheaper the ticket price is. The sales manager collected information for the last year on how many bought their tickets at each price: Ticket Price (in dollars) # of Customers (in thousands) 5 15 23 27 20 10 89 125 135 150 178 198 What is the coefficient of correlation between the ticket price and the number of customers purchasing at that price?

The demand for a commodity generally decreases as the price is raised. Suppose that the demand for oil (per capita per year) is D(p)=1000//p barreis, where p is the price per barrel in dollars. Find the demand when p=55. Estimate the decrease in demand if p rises to 56 and the increase in demand if p is decreased to 54. The demand D(55)= The decrease in demand =? barrels. The increase in demand =? barrels.

Using elasticities, you will be able to determine whether this price change will lead to a rise or fall in total revenue in this market. Using the midpoint method, the price elasticity of demand for pistachios between the price levels of $15 and 59 per ton is 0.33, meaning that between these two points, demand is inelastic. Thus, you can conclude that the grower's claim is incorrect because total revenue will increase due to the technological improvement. Confirm your previous conclusion by calculating total revenue in the pistachio market before and after the technological improvement. Enter these values in the following table. Before Technological Improvement After Technological Improvement

The coefficient of income in a regression of the quantity demanded of a commodity on price, income and other variables is 10. Calculate the income elasticity of demand for this commodity at income of $10,000 and sales of 80,000 units. What would be the income elasticity of demand if sales increased from 800,000 to 900,000 units and income rose from $10,000 to $11,000? What type of good is this commodity?

Quantity of A traded 10,000 15,000 Household Income | Price of B $3000 Price of A $1.10 $1.50 $0.90 $2500 $1.20 (i) Determine the price elasticity of demand for A, income elasticity of demand for A and the cross price elasticity of demand between A and B using the mid-point formula. Based on the elasticities, classify A in terms of its price and income elasticities of demand and establish the relationship between product A and product B. Given that the price of product A increases by 5%, household income increases by 3% and the price of product B increases by 2%, explain and compute the effect on the revenue from product A, assume each of the changes occurs separately. (ii) (b) The demand and supply functions of wheat is given as P = 20 – 0.05Q and P = 10 + 0.05Q, respectively. Solve for the equilibrium price and quantity in the wheat market. If the government implement a price floor of $18 per unit of wheat to help the wheat farmer, compute the consumer surplus, the producer surplus…

To discourage the energy drinks market, lawmakers, including Senator Miller (D-CA), have called for an aggressive tax on energy drinks. The Miller Bill would place a two dollar tax on energy drink tall cans (that on average cost $2.50) in all American markets. Other members of Congress led by Senator Cruz (R-TX), however, believed that tax to be too high, so the Miller Bill was amended to decrease the size of the tax to just one dollar. 1. Draw a graph with demand curve, supply curve, equilibrium price and quantity, tax price, tax incidence, tax revenue, and deadweight loss. Sen. Cruz claims that this smaller tax still accomplishes the goal of destroying the market for energy drinks, while Sen. Miller vehemently disagrees, stating that energy drinks will still be consumed, but to a lesser extent. Which senator is correct, and how can you tell from the graph? I 1:22 9,
