News

• This is the News section for this website. It is the primary news source for the course Economic Dynamics (FH27041). Video and PDF resources will be linked from this page, and homework and tests will be announced here.

  There is also a Teams channel for Economic Dynamics and the course page on Manaba. If any resources are placed in either channel, they will also be announced and linked from this page. If you were registered in TWINS by 18:00 on October 5, you should be registered in the team as well. Otherwise you can use the registration key hpnvmew to join (your university address must be registered in Teams to use this code).

• All PDFs and the Lecture 5-1 video are available in the Economic_Dynamics_2023_FH27041 Team Files > Class Materials folder. The action for a plain click is to stream to your browser. If you really want to download, you have to select it with the checkbox at the left and select download as the action.

Fri Oct 13 05:33:13 2023

• Lecture information, videos, and PDFs are now available from the table in the Lecture Schedule. Future updates will just point to the Lecture Schedule.

• Lecture 2, Part 1: Introduction to modern economic growth theory: Robert Solow's pure dynamic model. (video 2-1 / PDF 2)

• Lecture 2, Part 2: Facts about economic growth and applications of Solow's model. (video 2-2 / PDF 2 from page 48)

• Homework has been assigned, as in the lecture video, Part 2, at the end. Due date is October 20. Please wait for an announcement to submit, the submission email address is not working yet.

• I have updated Part 3 (PDF 1-3) again with minor changes to the content.

Wed Oct 11 16:07:23 JST 2023

• I have replaced the PDFs for Lecture 1, Part 2 (PDF 1-2) and Lecture 1, Part 3 (PDF 1-3). I changed the format of the slides from those used in the videos but the content is the same except for updated information described below.

  The content of the Part 2 PDF is now identical to the slides used in the video.

  Important: In the Part 3 PDF, to conform to university policy, class participation has been removed from the grading policy. The replacement PDF has been changed to reflect this, but the video has not. The video is incorrect. The current PDF (which states "40% Research proposal, 20% Presentation, 40% Homework") is correct.

  The course contact addresses have been changed in Part 3. My email program has been upgraded, and I have not confirmed that the addresses work. Please save all messages you send to me until you have confirmation of receipt. (You should do that anyway, but it's especially important. You should also save the receipts because that is your proof that you sent it in case of any data loss.)

Mon Oct 9 13:21:03 JST 2023

• This page is still incomplete, but now all information is accurate except where marked as subject to change.

• You should not do or submit homework yet. The mail software on the host has been updated and the dynamics-help and dynamics-hw addresses don't seem to be working.

Fri Oct 6 10:33:51 JST 2023

• There are reports that the videos won't open. Try opening https://web.microsoftstream.com/browse?q=FH27041, and then find the videos (they're not in order! Thank you Microsoft.)

Thu Oct 5 23:42:56 JST 2023

• There are 3 videos for lecture on October 6. I am sorry, I have not confirmed that the linked PDFs accurately reflect the material in the videos. I will do that over the weekend and provide replacements where appropriate on Monday. The PDF for Part 2 is actually from another class, the modeling starts a few slides in.

  Information published below this point in this page relates to past instances of the course. It may be useful, but you should not rely on its accuracy with respect to policies in the 2023 instance of the course.

Course Outline and Goals

Economic Dynamics studies the "motion" of economic processes: disequilibrium behavior in convergence to equilibrium, growth, irreversible processes like consumption of exhaustible resources, and the acquisition and use of information in dynamic games and finance.

Goals of the course include:

• Good conceptual understanding of dynamic vs. static analysis.

• Conceptual grasp of the analysis of growth and convergence.

• Basic knowledge of specific applied theory areas, including:

  • Economic growth

  • Exhaustible resources

  • Stability of equilibrium

Other topics will be covered according to class interest, time constraint, and the whims of the instructor.

Lecture Schedule

The lecture schedule is currently incomplete. It probably won't change much but will be updated soon. Lectures 1 and 2 are accurate. Dates (including holidays) are correct.

Links to Homework Assignments

This section is now accurate but incomplete.

Various resources for examination study

There are no examinations this year because the course is entirely online. This section remains for your self-testing and if you're curious.

• Midterm Guide (from 2012, not recently updated)

The following resources contain sample and actual test questions for midterms and finals, with sample solutions for some of the questions. These solutions are samples; they are not necessarily complete, and not everything in every solution is necessary for full credit.

• Testbank of sample questions

The testbank is the primary resource. It is intended to contain all previous test questions (some of which are no longer relevant), some questions which have not been used yet. There may be some additional information in the past examinations below.

• Midterm 2016

• Midterm 2013

• Midterm 2012

• Midterm 2011

• Midterm 2010 (makeup)

• Midterm 2010

• Final 2005

• Midterm 2005

• About homework submission

  My host is working as it should be. Unfortunately, the university has decided to block mail to that host from off-campus, which seems to include s.tsukuba.ac.jp. For most students there is no way to send mail to me, and I don't know when this will get fixed.

  Send mail to turnbull@sk.tsukuba.ac.jp. The Subject field should be "FH 27041 Homework #(hw number)" in half-width Roman letters, where you replace the string "(hw number)" with the appropriate number. Without that exact Subject, my filter may miss your mail.

• Please resend homeworks #1 and #2, which were never received (the university's filter apparently throws away your mail with no indication to you or to me).

• Lecture 2 updated.

• Homeworks 3, 4, and 5 are at the end of Lecture 2

  They are due next week on Friday.

Thu Oct 11 01:01:48 2018
