A discussion of: “Global Sustainability (health, environment and monetary costs) of Three Dietary Patterns: Results from a Spanish Cohort (the SUN project)”

The CDC reports that over 40% of American adults are obese, which means a BMI of 30 or higher.

Now, we can argue about the BMI as a metric, but it does show that the number was 30% in 2000 and 40% in 2018. It is definitely capturing a trend, and a bad trend at that.

The CDC also points out the harm obesity causes.

Obesity-related conditions include heart disease, stroke, type 2 diabetes and certain types of…

A discussion of “A Skeptic’s Guide to Modern Monetary Theory”

A sexy new economic theory appeared in the last few years promising us that government debt really is nothing to worry about.

Modern Monetary Theory (MMT) says a nation that spends, taxes and borrows in a fiat currency they control can spend as much as they need without worrying about becoming insolvent. Whatever amount of money is needed can be printed.

I dismissed it when I first heard of it because that sounded ludicrous — debt does not matter? The size of the money supply does not matter?

While it…

I like to think of ways to teach that will make the experience more engaging for both the students and myself.

The crux of the problem is the gap between teaching and learning. Me standing there saying things to you does not necessarily translate into you learning.

Holbrook and Lean (2020) are addressing this issue but also focusing on what they call a teacher-student divide due to technology.

Essentially, the college students of today have been called digital natives because the online world has been an extensive part of their lives growing up. …

A Discussion “The Social Responsibility of Business: Milton Friedman Reconsidered”

As an economics professor, I know I have some misconceptions to overcome every semester a new crop of students appear in my intro microeconomics course.

Economics is about greed. It is immoral. Capitalism is bad.

Elrick and Thies (2018) offer an example of these bad ideas being proliferated due to a bad headline incorrectly summing up Milton Friedman’s free market ideas. And over the years, that incorrect view has been tagged to anyone professing free market views in the vein of Friedman.

Adam Smith’s view of the Invisible Hand first…

Do women earn less than men because of discrimination? Or are they making choices that lead to lower pay?

Why on earth would someone choose lower pay? Because the lower pay may come with other benefits such as scheduling flexibility, less overtime hours or other quality of life options.

Sorkin (2017) says that men earn more than women because they are more likely to work in higher wage industries, and within those industries, they are more likely to work at the higher wage firms.

He examines two theories to explain the observed pay gap between men and women.

1. Discrimination Explanation…

A Discussion “Initial Impacts of the Pandemic on Consumer Behavior”

Here is an early look at the impact on consumers’ income, spending and savings behavior from the dreadful economic shock of the coronavirus pandemic and shutdown.

As an economist, I never would have said it was possible to shut down the economy, so I watched in horrified awe as it happened.

Economics is classified as a social science, and we are criticized for how much we get wrong. Part of it is due to the interdependence of the economy that is more complicated than our mathematical models can capture.

But…

A discussion of “Revisiting the Purpose of Business”

I am an economist and a lot of what drew me to the field early on is the Adam Smith story of the Invisible Hand.

Briefly, it is the idea that our self-interested nature is channeled, as if by an all-knowing Invisible Hand, to an allocation of our resources that is optimal, even better than what a planner could have come up with.

Taking something that is of questionable value, our self-interested nature, and creating something that benefits all, — it seemed so beautiful and compelled me to study economics in the…

A Discussion of “The Productivity-Wage Premium: Does the Size Still Matter in a Service Economy?”

We turn today to another piece in the puzzle of determining why it seems income inequality has grown in the United States in recent decades.

Knowing why a variable is trending a certain way makes it easier to devise policies to alter it or address it if it cannot be altered. Without an understanding of what is happening, new policies can make things worse.

A previous article I reviewed examined a feature of our economy in recent years that impacts this issue: more industries are…
