Unformatted text preview: Name: ANSWER KEY ECO 1104A INTRODUCTION TO MICROECONOMICS MIDTERM EXAMINATION Professor: David GrayOctober 23, 2002 INSTRUCTIONS a) The allotted time is one hour and twenty minutes. This examination counts for 25 % of your course grade. It consists of short answer questions and problems, and you should answer all of them. There are a total of 50 points. b) You may not consult with any written materials whatsoever, including other students' papers, and no conversation is permitted while the examination is in progress.

What are they? (Another hint: we see all three of them operating in the market place). (2 points) CONSUMPTION ACTIVITIES, PRODUCTION ACTIVITIES, AND EXCHANGE ACTIVITIES Note: Despite the two hints given, most students missed this question. Students incorrectly zeroed in on the word three, and then responded what?, how?, and for whom?, without reading the question carefully and thinking hard about what question was actually being asked. Do not answer any question too hastily: instead, you should spend a little time zooming, which means to focus on the part of the course to which the question refers. 3) Define the term opportunity cost and explain the relationship between scarcity, choices, and opportunity costs. (2 points) OPPORTUNITY COST IS THE COST OF THE HIGHEST FOREGONE ALTERNATIVE WHEN AN ECONOMIC ACTOR MAKES A CHOICE.
