OCHESTER 1. (12 points) Supply and Demand for Riesling The Finger Lakes region of New York State is known for its Rieslings. The demand function for bottles of wine from this region (in 100,000s) has two variables average annual income of purchasers. The functional form is: Qd=-2Pd-5+0.0011, where the price of wine and the Qd is quantity sold, Pd is the price of one bottle of wine, and I is equal to average income. Assume average annual income today is $30,000. A) (3 points) Calculate and plot the demand curve. B) (3 points) Calculate and plot the demand curve for I = $35,000 on the same graph as used in part a. == C) (6 points) Now assume a supply curve, Qs = 25P, - 175. Plot the supply curve on the same graph. Compute the equilibrium prices and quantities for the two demand curves.

Livestock farmers frequently give antibiotics to their herds. The antibiotics create drug-resistant bacteria, making them less effective. This harms future users of antibiotics who will be using less-effective drugsA. What is the nature of the market failure? (3%)B.

4. (0,.7 or 10) Provide an example of product differentiation using any industry you want (e.g., fast food, shoes, clothing, etc.)

Part I The headline about Russian wheat suggests the market is broken. Illustrate the supply and demand for Russian wheat indicating the price in relation to equilibrium. Explain why the market is "broken," and what needs to occur to fix the market. Russian wheat trade falls silent as price floor leaves market 'broken' HIGHLIGHTS Russian wheat not offered below $275/mt since late March Government believed to have intervened to support prices, farmers Traders assess pricing power of Russian state in global market Part II Derive the demand and supply functions using the numbers in the table and calculate equilibrium price and quantity. Graph supply and demand and indicate equilibrium price and quantity. The government wants to help sugar consumers by setting the price at $2.50. Explain the outcome (in terms of Q and D) and your advice in this situation. Illustrate the effect on the same graph and be sure to indicate price and quantities. Price/bag Quantity demanded (bags of sugar)…
