Have you ever taken an economics class?
If so then the content of this blog post may already be familiar to you. Today I will be looking at rational choice, the concept of sunk costs, and how they can be applied not only to economics but everyday life as well. These concepts made so much sense to me when I read my Economics text that I wanted to share them!
Every time you make or anyone else makes a decision, there will be costs and rewards associated with each choice you can pick.
If for example you are at Dunkin Donuts and trying to decide if you want a glazed chocolate donut. Your cost/rewards might look like this:
Rewards: I love chocolate, My tongue will feel like angels are dancing on it.
Costs: the glaze is sticky, It costs $1, I will be one step closer to being fat.
You are going to pick the option that maximizes your rewards and minimizes your costs. What is the best option for you? What choice will net you the most benefit? Is it more important for you to have a tasty treat or did your new diet tips app make you think twice?
Either way at the end of the day, you made a decision. This is an example of rational choice. Whatever our decisions, we always make them rationally. What about drug users? Are they acting rationally?
My Economics textbook would argue “Yes.” Even in extreme cases humans still act rationally.
What if you saw a man high on drugs jump out the window in front of you. You might say “He clearly wasn’t making a rational choice.” But the truth is he was. In the donut example, I talked about the individual costs and rewards for you eating the donut. The rewards and costs are made from our own sets of information, feelings, and preferences. Many people sometimes incorrectly assume that others will make the same decisions they do because they perceive that others use the same set of information they do.
Initially, you may assume that the man who jumped out the window isn’t rational, but you don’t know if it was or not. You do not share the same set of information. What if the only reason the crazed drug man jumped was to get away from the three-headed dragon monster that was chasing him down the hallway?
If a three-headed dragon monster was chasing you, would you jump out the window? I know I would.
Now that rational choice is out of the way we can start to explain the concept of sunk costs.
Investopedia says that “A sunk cost is a cost that has already been incurred and thus cannot be recovered.”
We make decisions in the present.
Each decision we make should therefore logically be decided by the “Now.” Costs that were previously incurred, already invested, or gained in the past shouldn’t have any weight in your current decision. But never the less, many people do make decisions with these “sunk costs” in mind.
A good example of people making this mistake comes from an article in the Wall Stree Journal. A woman who runs a cat cafe was quoted as saying
“I’ve already sunk so much money into this business, I can’t just walk away,”
When deciding to keep her business open, she should only be concerned about the present and future costs. Sunk costs are behind her. If she does end up factoring them into her calculus then she is making a poor choice. It is in her best interest to limit her rational analysis to just the costs and rewards associated with keeping the store open right now and in the future. Sunk costs should mean nothing.
Hopefully, you have become more informed about these random economic concepts. Since learning about them from my textbook, I know I have applied them in my daily life.
I hope you do too, but only if the rewards for you outweigh the costs.
