Should economists shy away from teaching hard topics for fear of offending someone’s moral sensibilities? Should we restrict ourselves to the market for ice cream? The tagline of our textbook, Modern Principles, is See the Invisible Hand: Understand Your World. We take understand your world seriously and we teach topics that other textbooks do not such as the economics of network goods like Facebook or the economics of tying and bundling which students see regularly when they purchase cell phones and minutes and Cable TV.
The world, however, is not always a pleasant place and so we also discuss modern slavery and how the concept of the elasticity of supply can help us to evaluate programs like slave redemption. It’s important to teach this material with seriousness, it’s not an idle exercise in “freakonomics,” and it’s possible to misstep but we think students need to see economics as a vital discipline that can be used to make the world a better place, even if only one small step at a time.
Here is Tyler on elasticity and the economics of slave redemption. This is from the elasticity section of our course at MRUniversity, released today along with taxes and subsidies. You can also find a lengthier treatment with more details in Modern Principles.
