Slides & Notebooks

• The slides below are available in three different versions: an HTML version (used in classes), an HTML long version (for quick reading), and a pdf version (students can add notes). They are used as supporting material in the theoretical sessions.

• The active notebooks and some data files (csv files) are inside a zipped folder that can be downloaded by clicking on the link below. They are used in practical sessions (sometimes in theoretical ones as well).

  • Remember that we have to double-click on the zipped folder to get the original folder with the files.

  • Remember to keep all files in the same folder on your computer (or in the cloud).

  • The active notebooks ** _ cannot be run by the usual double-clicking _ **. They can only be opened through the Pluto window. So, we have to start Julia and Pluto in order to run them.

• The static notebooks are HTML versions of the (active) notebooks. They can be opened simply by clicking on the link below. We can see their contents on a browser (Chrome, Mozilla, Edge, or any other) and navigate on the HTML file, but we can not change their contents.

For those that want to have a flavor of what macroeconomics is all about, you can read this article by Paul Krugman in the New York Times, February 8, 2023: $$ Revisiting the Summer of Stagflation

In particular, see if you feel more inclined to favor Larry Summers’s dim view on inflation and unemployment (that containing inflation would require five years of 6 percent unemployment) or the more optimistic perspective of Paul Krugman: inflation seems to be rapidly coming down … and unemployment is [surprisingly] coming down as well.

Note. This article is made available here strictly for teaching purposes.

Warning

There was a typo in equation 5, slide 21. The new version was inserted on March 20 (17:00h). The correct version of that equation is the following: $$\begin{array}{}\text{(5)}& {\mathbb{E}}_t{y}_{t+1}=\alpha +\beta \cdot {\mathbb{E}}_t{y}_{t+2}+\theta \cdot {\mathbb{E}}_t{x}_{t+1}\end{array}$$
