IF YOU TOOK AN economics class in high school or college, you might see its usefulness as limited to helping with your grade point average. But the basic ideas you learned can still be valuable. Take this introductory microeconomics question: In a typical transaction, who has more power, the buyer or the seller?
When I started teaching economics many years ago, I gave the nod to buyers. Invoking the notion of “consumer sovereignty,” I’d explain to students that buyers have the power to vote with their feet—by walking to another store.

HERE’S THE LEAST surprising thing you’ll read this week: You can’t control the financial markets. They’re driven by news—and we simply don’t know what news we’ll get in the weeks and months ahead, whether it’s about the spread of the coronavirus, its impact on the global economy or something else entirely.
But don’t despair: There’s also much that we can control, including how much we save and spend, the amount of investment risk we take,

I’M WRITING THIS just before 6 a.m., following a few days during which world stock markets caught their own version of the flu. Frankly, I can’t sleep thinking about what’s happened—and especially about the investors who panicked and locked in their losses, just like so many folks did in late 2008 and early 2009.
It took me a few minutes to muster the courage to look at my 401(k). When I did,

HOW OFTEN DO YOU think about money? Hey, you just did. Seriously, we think about money every day and sometimes every hour. Some studies say we ponder financial matters even more often than the old standby: sex.
We’ve been thinking about the stuff for a long time. Money goes back about 3,000 years. Paper currency can be traced to China in 700 BC. They didn’t fool around: Their currency stated that all counterfeiters would be decapitated.

ONE OF MY FAVORITE movies of recent years was Hidden Figures. There’s a pivotal scene where the hero, Katherine Johnson, realizes they need to use an ancient numerical technique known as Euler’s Method to solve the trajectory equations for John Glenn’s mission. This involves breaking a complex problem into very small pieces, solving each part, and then summing them to get the solution.
Over my engineering career, I used various numerical integration techniques to solve complicated problems.

FROM AN EARLY AGE, I was amazed at the power of mathematics to model our world and solve real world problems. In engineering school, we studied a host of mathematical techniques that did just that. But I wish we’d spent more time on probability and statistics.
In 1989, I read a book that gave me a broader view of how probabilistic our world is and, at the same time, made me aware of how ill-prepared the general population is to understand these concepts.

BEATING THE STOCK market over the long term is no mean feat. Only a tiny proportion of investors—professional or otherwise—manage to do it. So why do so many people think they can?
Meir Statman, a finance professor at Santa Clara University, cites eight key reasons. In a new monograph titled Behavioral Finance: The Second Generation, he slots these reasons into two broad categories—five cognitive and emotional errors, followed by three expressive and emotional benefits:

I USED TO THINK anybody could be taught to manage money sensibly. I no longer believe that.
When I was in my 20s and scraping by on a junior reporter’s salary, I had some sense for the financial stress suffered by everyday Americans. But after a handful of years of diligently saving, I was able to escape those daily worries. Many Americans, alas, never do.
This was hammered home when I recently took the financial well-being questionnaire offered by the Consumer Financial Protection Bureau (CFPB).

WHY DON’T WE SPEND our time and energy on financial issues that have the greatest impact? We’ll drive to a more distant gas station to save 10 cents a gallon, but fail to do all the maintenance needed to extend the life of our car. What lies behind this sort of behavior? The savings from getting the best price per gallon is concrete and immediate, while maintaining our car is long term and abstract.

BEEN A DILIGENT saver during your working years? Upon retirement, you’ll likely find it tough to transform yourself into a happy spender. This is not a problem you’ll read much about—because it isn’t exactly a widespread affliction.
The fact is, most folks struggle their entire life to control their spending, only to reach retirement with too little saved. At that point, they have no choice but to tighten their belt. Indeed, the statistics are alarming.

I RECENTLY READ about a trendy way to lose weight: intermittent fasting. Supposedly there are also health benefits. That got me thinking.
I’ve been roundly criticized for bashing the financial independence/retire early movement, otherwise known as FIRE, and for arguing that average Americans spend unnecessarily on all kinds of stuff, thus hampering their long-term financial security. My point of view hasn’t changed. But I’ve found room for compromise: Think of it as periodic financial fasting.

MONEY HAS ALWAYS caused me stress. As a child, I worried my parents didn’t have enough, even though I had no idea what sum would have been considered enough for our family of six. In college, I worried about accumulating debt. I ended up living so frugally that I managed to save nearly all of the Pell grant that the government awarded me. I not only graduated debt-free, but also had a sizable emergency fund in place as I moved into adulthood.

“RESOLUTE” IS THE wrong adjective to describe most of us at the start of a new year. We know what we should be doing for our future self. But within weeks, days and sometimes hours, we forget about the person we’ll become.
What can we do to improve our odds of success in 2020? As Stephen Covey taught us years ago in The Seven Habits of Highly Effective People,

GIVING GIFTS DELIVERS significant emotional and health benefits, or so says the research. But I find much depends on how the actual giving takes place.
My best giving lesson occurred many years ago. At a rural busstop on the island of Crete, off the coast of Greece, I sat next to an old local woman dressed in ragged clothing and torn shoes. Neither of us spoke the other’s language. She carried with her a small bag of fresh peaches and motioned for me to take one.

“DON’T STOP THINKING about tomorrow,” sang Fleetwood Mac. It’s a shame they weren’t financial advisors.
We save money today so that we—or our heirs—can spend at some point in the future. A good tradeoff? I strongly believe that it is, and you wouldn’t be a HumbleDollar reader if you disagreed. Still, during this season of holiday shopping joy, it’s worth reminding ourselves that, yes, we should indeed think about tomorrow.
Living for Today.
