All
instructional videos that are available on The
Snarr Institute are organized below by course: Principles
of Macroeconomics, Business Quantitative Methods
(statistics), and Labor Economics.
An example is shown below. In this video, I analyze the economics of
Hurricane Katrina (at minute 0:00), math teacher shortages (15:20), minimum
wage hikes (22:30), immigration (26:50), and Lebron
James's pay (31:00).
