Limit Pricing is a fascinating yet widely unexplored concept in economics classes. When teaching our students about how monopolists and/or firms with market power make their decision regarding output and prices, it usually follows a simple premise - firms choose the level of output to maximize profits, which occurs where marginal revenue equals marginal cost, … Continue reading Should Antitrust Agencies be Concerned about Limit Pricing?
Last Saturday, September 30th, I had the opportunity to share a little bit of my Brazilian Culture at the University of Kansas. Phi Beta Delta hosted this wonderful concert in which students from many nationalities shared music and/or dance from their heritage.

First clarification I want to make is the understanding that this post isn’t about whether firms should or not maximize profit – which can just as well be the theme for another post. Most Micro and Macroeconomic Theory start from the premise that each firm seeks to maximize profit, which is intuitively sound and can … Continue reading DO FIRMS MAXIMIZE PROFITS?

I have found that creating a dynamic experience for the classroom is the best way to keep students on their toes. Most of us are familiar with the learning pyramid … Continue reading Using Kahoot in the Classroom
This may sound to you like a pretty philosophical question, but I would like to go mathematical for a minute (bear with me)…then yeah, let’s get philosophical (because observation can only take you so far…let us reason through it too).

How often do you catch yourself or somebody else saying the phrase: "I have no time". Having no time per se isn't particularly different then saying: I have no space, in which we often refer to something that doesn't fit. The whole human experience in this planet is severely underlined by the whole concept of … Continue reading The untouchable dimension “Time”
Much of the early-on Undergrad-ECON classes focus on recognizing in what consists and Economic Environment and how it affect consumer's willingness to pay for a certain good and/or supplier's willingness to exchange his good for a certain monetary value. Sometimes the way in which those introductory courses introduce this subject is disguised by the distinction … Continue reading The so called Economic Environment
Externality is an Economic concept that arises whenever private parties fail to perceive some implicit cost or benefit due to the decisions they make. Is one of the forms of "Market Failure" that we encounter in our daily lives (i.e. situations in which market allocation won't result in a socially optimal result), and the main reason … Continue reading Externality and Trees
