Principles of Economics

 

Problem Set #1

Due Friday, September 6th, in class[*]

Short Answers  

 

1. Define opportunity cost and give an example from your own experience.

 

2. Economists are often criticized because their economic models do not fully and accurately describe the “real world”.  How might economists defend themselves against this charge?

 

3. What is the main difference between microeconomics and macroeconomics?

 

4. Explain the two main causes of market failure and give an example of each.

 

5. Which of the following statements are normative and which are positive?  Why?

(a)               Baseball players make too much money.

(b)               The price of computer equipment usually starts to fall after it has been on the market for a long time.

(c)                A $0.50 per gallon gasoline tax will cause some consumers to shift from using cars to taking public transportation.

(d)              Charging a toll on the NJ Turnpike is fair because those who use the turnpike pay for its construction and maintenance. 

 

6. Go to the library and find at least 5 topics that economists are currently writing about in academic journals.  Choose one article to represent each of your five topics.  At least 2 of the articles must deal with an issue you did not know economists studied (put an asterisk before the names of these topics) and at least 2 of them must be published prior to 1997 (this will require you to go to the stacks on the bottom floor of the library).  For each article, give the citation in AER format[†] and a short description (1-2 paragraphs) of what the paper is about (what questions are the authors trying to answer?), and what the author(s) find (what are their results, conclusions, and/or policy implications?).    I realize that you will not understand all aspects of the articles, but do not simply copy the abstract.  Many articles will deal with several topics, but you should focus on and summarize only the part of the paper which deals with the topic you’ve chosen. 

 

Restrict your search to the following journals: American Economic Review (especially the May issue), Journal of Political Economy, Quarterly Journal of Economics,   Review of Economic Studies, Review of Economics and Statistics, Journal of Economic Perspectives, and Journal of Economic Literature.   You may have more than one paper from a given journal, but they must be from different issues of that journal.  That is, two articles from the same issue of the same journal are not allowed.    Good ways to find papers: (1) go to the stacks on the first floor of the library and browse the recent issues, (2) use “EconLit,” a searchable database of economics literature for which there is a link on the library website (ask a librarian for assistance) or there’s a link on my page www.davidson.edu/academic/economics/foley/links.html, or (3) search  “JSTOR” (Journal Storage), www.jstor.org, which houses journal issues older than 5 years. 

 

 

Problems

 

1. Suppose Brenda knows the exact value, in terms of money, that she derives from eating nectarines.

 

            Number of Nectarines Eaten                      Brenda’s Total Value

                                    1                                                                      $1.00

                                    2                                                                      2.00

                                    3                                                                      2.90

                                    4                                                                      3.70
                                    5                                                                      4.30

                                    6                                                                      4.60

                                    7                                                                      4.55

(a) What is the marginal value to Brenda of eating the fourth nectarine?  Of eating the sixth nectarine?

 

(b) If nectarines cost $0.50 each, how many will Brenda buy?  How many will she buy if they are free?
