Each term (3 months) the current group of economics students completed a questionnaire as to how much they would spend on new purchases compared to how much they would save/pay off bills, if they suddenly and unexpectedly received a check for $1,000. The average MPC is shown in the table below. Month in which student poll was taken Average of students’ responses as MPC March 0.41 June 0.30 September 0.22 December 0.56 What do these MPC’s imply about the students’ thinking over the course of the year? (Enter response here.) What is likely happening in the economy during the same period of time?
Q.3 - An economist has estimated demand of D = 1000 − P and Supply of S = 400 + 10R for onions, where R is the number of days of rainfall. (a) Plot the demand and supply curves. (b) Show the equilibrium quantity and the equilibrium price on the graph. (c) Use Algebra to determine the equilibrium price and quantity (d) Use a new graph of demand and supply curves to show the effect of an increase in rainfall
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.

1. A Travel-Cost Method Now it is time for your first consulting job as an environmental economist. The Forest Service would like to know whether they should preserve some national forest land, previously slated to be logged, for hiking. You are helping do a travel-cost analysis to estimate the annual benefits of hiking in this area. Survey data has been gathered from 500 hikers who visited the forest last year. This forest did not charge an entrance fee. Using a statistical technique called regression analysis, you have controlled for differences in income, employment status, age, and other important factors that might affect the number of hiking trips taken. Taking these factors into account, you have developed the following relationship: Zone 1 2 3 Population in zone 1,000 3.000 2,000 Cost Per Hiking Trip Per Person 20 40 80 Hiking Trips Taken Per Zonal Person Per Year 8 6 2 where cost includes gas, tolls, fares, hotels, entry fees, and the value of time spent traveling. a.

PROBLEM (1) (Rational Choice) Suppose your friend is about to buy a digital camera. A digital camera is identified with three dimensions; 1) resolution (in megapixels), 2) optical zoom (a real number) and 3) battery life (a number of hours). For example, A = (8, 4, 20) is a camera with 8mp resolution and x4 optical zoom and 20 hours of battery life. When he goes into a store, he faces a menu of cameras. When comparing two cameras if camera A is weakly better than B on at least 2 dimensions, it is weakly preferred to the other; written A ≥preferred B. a) Is this preference relation complete? Transitive? Prove it or show an example where the property doesn't hold. b) Suppose the agent chooses from any menu of cameras, a camera that is (weakly) preferred to all other cameras in the menu. Would this choice function be rational, given (a)? Briefly explain your reasoning.
