final exam
(posted 09 Dec. 14.25)
 
Trade students,
 
Sorry it took me so long to finish writing your final exam. Click HERE  for the exam. I think the questions are pretty straightforward, so if you read the material, you should do well on this exam. You've got a lot of work to do, but you should do well on this exam.
 
As I've mentioned before, if you do better on the final exam than you did on the mid-term, then I'll drop the mid-term grade, so that the final will count as 80% of your grade for the course. Conversely, if you do worse on the final exam, then I'll take the weighted average of your mid-term (35%) and final (45%).
 
I want everyone to do well on the final, so work hard and write a good final exam!
 
Good Luck,
- Eric Doviak
 
ps: The final exam is on Thurs. 21 Dec. from 6:00 to 8:00 pm.

last class and final
(posted 03 Dec. 20.40)
 
Trade Students,
 
As I mentioned in class, I would like to discuss "Trade Policy in Developing Countries" next Thursday (7 Dec.). Please read chap. 10 in the Krugman-Obstfeld textbook and Rudiger Dornbusch's 1992 article in the Journal of Economic Perspectives.
 
Thursday will also be our last class, so I will distribute a copy of the exam questions after class.
 
The final exam will cover: The final exam will be on Thurs. 21 Dec. from 6:00 to 8:00 pm.
 
If you do better on the final exam than you did on the mid-term, then I'll drop the mid-term grade, so that the final will count as 80% of your grade for the course. Conversely, if you do worse on the final exam, then I'll take the weighted average of your mid-term (35%) and final (45%).
 
The idea here is to give everyone a strong incentive to do well on the final.

bring a blank check to class tomorrow
(posted: 29 Nov. 11.45)
 
Trade Students,
 
When we meet tomorrow, we will discuss the Friedburg-Hunt and Card articles. We'll be paying particular attention to the empirical methods discussed in those articles, so expect a question about them on your final exam.
 
Let's also have some fun with this topic. Here is a link to an article about Hazleton, PA's response to immigration  -- click HERE. In August, they passed an ordinance requiring everyone who rents a home, apartment, etc. (both owner and tenant) to get a license/permit from City Hall. One of the conditions for approval of a tenant's occupancy permit is that he/she show that he is either a citizen or legal resident of the US. Then in September, they passed an ordinance that suspends the business license of any firm that employs "unlawful workers" (immigrants without work permits) and suspends the rental license of any owner who rents to an "illegal alien."
 
The trouble with the ordinance is that it forces firms to fire any worker who is suspected of being an "unlawful worker" and forces landlords to evict any tenant who is suspected of being an "illegal alien." Only after the immigrant has lost his job and his home is he allowed to appeal. Not surprisingly, the Latino community is fleeing the City.
 
So read the articles and bring a blank check to class and let's send Hazleton a response!

ps:  No, this will not cost you any money! I promise.

articles for next week and for make-up
(posted: 10 Nov. 03.30)
 
Trade Students,
 
As I mentioned in class, for next week I would like you ALL to read the Downes (NYT 2006) article, the Card (JEL 2001) article, the Friedberg-Hunt (JEP 1995) article and the Borjas (JEP 1995) article.
 
The Downes article is simple and straightforward (After all, it's a newspaper article!), but the others articles come from the academic journals. Obviously, grad students will understand the material better than undergrads, but: "You still have to try, undergrads!"
 
I don't expect you to read these articles line by line and pick through each equation. I just want you to pull out the main ideas. Hint: read the first five pages, skip to the key regression results and then skip to the conclusion.
 
Bowing to popular demand, I have posted the articles for the Make-Up Exam and the articles for next week's lecture online.
 
Rather than use my website and incur the risks of copyright infringement issues, I decided to post the articles to BlackBoard. In fact, I went ahead and posted everything to BlackBoard! If you don't have a Portal Login yet, then it's high time you got one! Click the "Register Now!" link and the system will verify your status by using your last name, Social Security Number, date of birth, etc. It's a veritable treasure trove of material for your Trade course!
 
Have fun!

a couple of files
(posted: 04 Nov. 00.30)
 
Trade Students, 
 
Bowing to popular demand, I have posted two files. 
 
One file contains an example of the Stolper-Samuelson Effect -- click HERE. The Stolper-Samuelson effect is a critical part of the Factor Price Equalization Theorem, so I highly recommend these notes to anyone who is doing the make-up exam. 
 
To keep the example simple, I used Cobb-Douglas production functions to derive a relationship between the relative price of cloth and the relative wage. The example assumes that you know how to take the first derivative with respect to labor to obtain the marginal product of labor. If you're not familiar with derivatives, then maybe these notes on Calculus Tricks will help you -- click HERE
 
The other file contains the email that I sent about Comparative Advantage in the Specific Factors Model. The file explains why it is WRONG to say that the US has a comparative advantage in manufactures because the US has a higher capital-land ratio than Africa. For that file -- click HERE.
 
Hope this helps,
- Eric Doviak

make-up exam -- factor price equalization
(posted: 28 Oct. 12.10)
 
Trade Students,
 
For a copy of your make-up exam -- click HERE. Students who missed the in-class mid-term exam are (obviously) expected to submit answers to this exam. 
 
The exam is also for students who did not do well on the mid-term exam and would like to improve their grade. If you get a better grade on the make-up than you did on the mid-term exam, then the mid-term grade will disappear.
 
To assist you, I have scanned a copy of my notes on Factor Price Equalization -- click HERE.
 
 
a few words of advice
 
Write thorough and complete answers to the questions. EXPLAIN. EXPLAIN. EXPLAIN. 
 
For example, "... because the United States has a higher opportunity cost of producing shoes" is NOT an answer! Why does the US have a higher opportunity cost of producing shoes? 
 
Oh and by the way ... if the Production Possibilities Frontier is concave to the origin, then wouldn't the US and its trading partner both produce at the point where their opportunity cost of producing shoes is equal to the world relative price of shoes? ... Yes, they would!
 
So answer the questions thoroughly and completely and provide detailed explanations! 
 
Also, I have given you a copy of my notes to assist you, NOT to give you the answers! If you understand factor price equalization, then you should be able to explain the theorem in your own words. So don't rewrite my notes! 
 
Copying somebody else's work doesn't teach you anything. Teach yourself the factor-price equalization theorem and then explain it to me. Show me that you understand this material!
 
Good Luck,
- Eric Doviak

class schedule and upcoming exam
(posted: 1 Oct. 12.00)
 
It took more time Heckscher-Ohlin model again last Thursday, but I think the extra time helped you develop a strong comprehension of the model and of the Rybczyński and Stolper-Samuelson effects. You can be sure that those topics will appear on the exam on 12 Oct.
 
Undergraduates -- be sure to read KO chaps. 1 - 4 thoroughly and do HW # 1 - 3.
 
Grad students -- be sure to read Feenstra chaps. 1 - 3 and the two Jones articles and do HW # 1 - 3.
 
On Thursday, we'll discuss HW #3 and conduct a review for the mid-term exam (Thurs. 12 Oct).
 
For your convenience, click HERE to download HW #3.

Homework #3 and Class Schedule
(posted: 22 Sept. 15.30)
 
Students,
 
Homework #3 -- click HERE
 
Thank you for your patience yesterday. I apologize for not giving you a break. Please understand that I needed to finish the description of the Heckscher-Ohlin model before the end of the class period.
 
Now that we have finished a survey of the three basic trade models (Ricardian, Specific Factors and Heckscher-Ohlin), it is time to discuss the predictions of those models in more depth. To that end there is no new reading for next week.
 
Instead, I want you to catch up on the reading. You should have read the first four chapters of Krugman-Obstfeld. Graduate Students should have read the first three chapters of Feenstra and the Jones articles.
 
Once you finish reading them, READ THEM AGAIN !!!  I want you to learn this material in depth.
 
When we meet again on Thursday, I will finish discussing the the Heckscher-Ohlin model and then we will begin discussing Homework #3 -- click HERE.
 
It's a very long set of questions and it will take at least two weeks to get through it all, but it will help you learn the material in depth.
 
All the best,
- Eric Doviak

Links to Homework and My Notes
(posted: 15 Sept. 12.36)
 
Students,
 
Here is a link to Homework #2 which we will discuss in class on Thurs. -- click HERE  You should also read about the Heckscher-Ohlin model in Chap. 4 in the Krugman/Obstfeld textbook. 
 
Grad students:  I hope the discussion of the Heckscher-Ohlin model will resolve all of the troubles you're having with the Jones articles. And to make sure that it does, I will incorporate a lot of Jones' material into the undergraduate lecture.
 
I have also scanned the answer to the graduate problem in HW #1 -- click HERE
 
I also scanned my notes on the "General Properties of Production Models" (taken from Jones/Scheinkman) -- click HERE
 
Keep working hard. I'm confident that we'll turn a corner next week.
