Using the blank graph below, draw and label all the curves needed to show a negative externality and, show on your graph the change in total social costs that occurs when moving from the market equilibrium to the social equilibrium. Make sure to clearly identify and label which quantity is the market equilibrium (QME) and which is the social equilibrium (QSE). Please use a straight-edge when drawing.

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?

Greenhouse gases trap heat and make the planet warmer. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years. In this part, you will draw two pie graphs. A pie graph is used to show how a certain quantity has been divided into several parts, as well as to show the comparisons among these parts. 1. The data table below shows the total U.S. greenhouse gas emissions by economic sector in 2013, in million metric tons of CO2. On the pie graph provided, complete the graph to show the percent of greenhouse gas emissions for each economic sector. Label each section of the pie graph with its economic sector. The percent for "Agriculture" has been drawn and labeled for you. Economic Sector Electricity Transportation Industry Commercial & Residential Agriculture Percent of Greenhouse Gas Emissions 31 27 21 12 9 80 75 70- 85 65 95 90 wlad Percent 0 100 Agri- culture 55 50 45 10 40 35 20 25 30

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.
