ECON 1B03 Final: Exam Study Guide ECON 1B03

PROBLEM SET ONE -2 - PRICE-ELASTICITY OF DEMAND

Column I - determine the Price-Elasticity of Demand Coefficient. Find material in Chapter 6 and the Powerpoint of Elasticity Chap 004 19e.ppt

change in quantity demanded change in price

E_D = ---------------------------------------- ∕ ----------------------------

sum of quantities demanded / 2 sum of prices / 2

The data in the first four columns represent price (P) and quantity demanded (Qd) in time 1 (before change in price) and time 2 (after change in price). Note that results should be expressed in absolute terms (see paragraph Elimination of Minus Sign). For example, -1 should be expressed as │1│.

Column II – Based on topic concerning Interpretations of E_D, indicate which applies based on how the quantity demanded changed subsequent to a change in price (elastic, inelastic, etc.)

Column III - you need to determine if the good in question would be considered a necessity, a luxury or neither.

Column IV – Indicate, in monetary terms, how much is the change in total revenue or total expenditure (TR = P X Q_D), from the first price level to the second.

Column V - the direction of the change, also in monetary terms, that is, increasing or decreasing, and by how much? (show a + sign for increasing and a – sign for decreasing).

Note: for any monetary result please include the applicable currency symbol ($, €, etc.)

Essay question: 50 points

11. Use the agricultural commodity that you selected in Chapter 1 and choose one agribusiness that buys it. Investigate the agribusiness using the Internet and other resources, and then write an essay addressing all or as many as possible of the following aspects of the agribusiness:

Size

Sales

Scope of product line

Worth (if public)

Number of employees

Locations globally

Market structure

Industry sector

All your answers/discussion should be typed in one essay that is at least 15 lines long (using formal English, correct paragraph and sentence structure, and making sure your ideas flow well from one sentence to another) using Times New Roman, 12 point, double space and 1-inch margins all around. Before submitting the final essay, use the “Spelling & Grammar” function of the MS Word to correct grammar.

At the end of your essay, provide the full citation record in alphabetical order in your list of references. For examples, visit: http://www.saea.org/wp-content/uploads/2013/08/reference-style-sheet.pdf. Please, note that the list of references does not count toward the minimum required 15 lines. Include your references in the text as “(Smith, 2015)” when citing at the end of a sentence, or “According to Smith (2015)” when citing at the beginning of a sentence. For example,

Negative publicity is a key determinant affecting consumers’ buying decisions (Ahluwalia, Burnkrant, and Unnava, 2000).

According to Cawley and Rizzo (2005), pharmaceutical products in the same therapeutic class experienced negative spillover in terms of lost sales.

Note: Most of the future essay questions will build on this essay question and/or the one agricultural commodity that you choose. This means that if there is little information on the agricultural commodity that you have chosen for this essay question, you should consider choosing a more common agricultural commodity on which ample information is available. In addition, this course will require you to compile all your answers to the essay questions into one term paper to be submitted by the end of the course. This means that the more effort you put into answering essay questions now, the more material you will have accumulated for your term paper by the end of the semester.

TYPE YOUR ANSWER TO THE ESSAY QUESTION 11 BELOW USING AS MUCH SPACE AS YOU NEED. THEN, PRINT THE HOMEWORK ASSIGNMENT AND SUBMIT THE HARD COPY.

Section I: Supply & Demand Analysis (Chapter 3) In each of the following 10 questions, show what happens to the Demand, Supply, equilibrium price and equilibrium quantity of copper. Show an increase by use of +, a decrease with a -, and no change with 0 (that’s a zero, not an O or o). Although in the real world, both supply and demand are constantly changing, in the model we are using here, only one curve shifts per problem. So, if demand goes + or -, supply will be 0, and vice versa. In no case will equilibrium price or equilibrium quantity be 0. You may want to sketch out the supply and demand curve analysis to help in answering the questions. You will also be required to identify which determinant (of demand or supply) has changed, thus causing the shift. Rather than actually writing in the determinant, fill in the blank with the number that corresponds to the relevant determinant, based upon the following list. You may want to refer to the lecture notes entitled Determinants of Demand & Supply in the COURSE CONTENTS section. For questions 1 - 10, refer back to this list. Some you may want to use more than once, some you won't use at all. Copy and paste this list to an MS Word document and then print it out if you don't want to keep scrolling back and forth between this list and the question you're trying to answer. Determinants of Demand: 1. Change in buyer tastes 2. Change in number of buyers 3. Change in income 4. Change in the prices of related goods (on the demand side) 5. Change in consumer expectations Determinants of Supply: 6. Change in resource prices 7. Change in technology 8. Changes in taxes and subsidies 9. Change in prices of related goods (on the supply side) 10. Change in producer expectations 11. Change in the number of suppliers. For example, if a rightward shift in the supply curve for an item were caused by an increase in the number of producers of that item, you would indicate this be entering 11 into the relevant blank. If the demand curve shifted to the left because people didn't like that item anymore (like mimeograph machines), you'd enter 1 into the blank. Q#1 President Trump signs into law a bill that says the U.S. government will subsidize the construction of new homes, office buildings, bridges, and other infrastructure projects requiring copper. Demand; Supply: Equilibrium Price: Equilibrium Quantity Exchanged; Which determinant changed?: Q#2 Non-capitalist economies around the world begin a phase of rapid economic development, construction and growth, becoming increasingly wealthy, as they begin to adopt more capitalist institutions, as in China, Russia, and the former communist countries of East Europe. Demand; Supply: Equilibrium Price: Equilibrium Quantity Exchanged: Which determinant changed?
