I have taught economic principles and lessons for more than 40 years. My hope has been for students and others to use these concepts in making better decisions for their personal and financial goals.

At the beginning of a new year, it’s common to give “top 10” lists for various activities and objectives. So, in the spirit of such lists, here are my top 10 useful economic lessons.

1. We can’t have everything. If what we desire is unlimited, but what we have to spend is limited, then we can’t have everything. We have to make choices, like between a new car and college savings, or a big house with a long commute or a smaller dwelling minutes from work. Tradeoffs aren’t fun.

2. Dollars change in value. Inflation, which means a rise in the general cost of living, is a fact of economic life. Fortunately, it has recently been tame. Still, any inflation reduces what dollars can buy. In just the last decade, the dollar’s purchasing power has declined 17%. There are many apps you can use to track the purchasing power of the dollar.

3. We’re paid to delay gratification. Most of us would rather have things now than later. That’s a natural instinct, one reason being we may not be around to enjoy things in the future. Yet there’s a reward for delaying gratification. Money saved for future use can earn a return, generally called “interest.” And through the magical power of “compounding,” consistently saving relatively small amounts can turn into big future amounts. For example, saving $1,000 each year for 30 years and earning 3% interest will result in a cumulative total of more than $47,000.

4. We pay to have more now. In contrast to the previous lesson, if you want more now — particularly more than your current income can support — you’ll pay for it. Let’s say you need $80,000 to buy the luxury vehicle of your dreams. You borrow the $80,000 and agree to repay the loan over six years. You will be charged an interest rate to do this. Using a modest rate of 3%, you will repay a total of $86,250; $6,250 more than the loan amount. Plus, the vehicle will likely depreciate in value!

5. Lost earnings is the cost of time away from work. There are many potential uses for our time. For parents with young children, a good example is spending time working and earning versus spending time with the children. The cost of an extra 10 hours per week with the kids is what the parent could earn in that 10 hours. In making this decision, parents must decide which helps their children more — extra household money or extra parental time.

6. Pursue your passion, but have a backup plan. I originally wanted to be an architect and build cities. Yet after a year in a design program, I found I had no design ability. My backup plan was to study the economics of cities, which led to several degrees in economics. I still enjoy admiring well-designed buildings, but I found my talent was in economics.

7. Use diversification, low fees and long-run thinking in investing. Investing is often thought to be hard, but it’s really not. Lots of research shows that following three principles is all most people need. First, invest in multiple investment categories, such as domestic stocks, international stocks, bonds, commodities and real estate. Put more in the riskier categories when you’re young and move toward safety as you age. Second, use low-fee mutual funds to invest in the categories. And third, keep your eyes on the long run. Avoid making big changes when particular investments rise or fall. “Buy and hold” should be your guide.

8. Recognize that change, not stability, is the nature of the economy. My wife worries when she reads of a local restaurant closing that it’s a sign of bad times. Usually that’s not the case. Statistics show more than half of new restaurants fail in the first year. The reason is people’s food preferences often change. Plus there are always new restaurants opening to offer more competition. Retail is now being rocked by technology making it easier to order from the internet. At any point in time, our economy will always be a shifting mix of old and new.

9. Pay for small risks; insure for big risks. Life is full of risks. Accidents, injuries and illnesses happen all the time. It’s just that we don’t know when they will occur. We can pay to handle risks by purchasing insurance. Yet all risks aren’t created equal. Small risks that don’t cost much should be paid out of our pockets. Spending on insurance should be reserved for big risks that can cost us a lot. And one last point. If you buy insurance and never use it, you’ve not wasted money. You’ve purchased “peace of mind” for dealing with uncontrollable risks.

10. Track your personal economy. My late mother was a big planner, especially with money. She kept our family on a strict budget. This helped my parents’ family in two ways. First, it helped them meet goals, such as paying for a new vehicle or purchasing my father new tools for his carpentry business. But it also gave my parents information about where their money was going, and if adjustments needed to be made. Fortunately, with modern technology, tracking spending is easier. However, you have to commit to do it.

I encourage you to think about these lessons and see if they can help you. Some say a new year and a new decade is the time for new ideas. You decide!
