Cost – Benefit Analysis and Opportunity Cost: Practical Use of Economics
The broadness of economics makes it difficult to distinguish its practical uses. For Economics in a sense, is used on a daily basis by anybody who makes decisions: from the common fish ball vendor to the lustrous financial managers.
This article focuses on the practical use of economics in our everyday lives. The topic is actually quite ironic, in a sense economics is used on a daily basis by every living human being (living meaning being able to make his or her decisions). Economics is not exclusive to the Economics majors out there nor is it reserved for those in the stock market and the government. It is applied and used by everyone- the ‘Masa’ as we commonly refer to them.
It is the 15th day of the month. Mang Pandoy just got his 5000 Pesos earnings from the construction firm he is working for. Mang Pandoy has a wife and 8 children to feed at home. He needs to buy dinner tonight, his options are sardines or noodles but he can also buy lechong manok. Surely lechong manok can make his family more satisfied, although will he risk wasteful spending on a delicious dinner. He could also opt to go with noodles to save more money; after all raising 8 children requires a lot of resources. He must weigh the benefits of the two choices – in this case lechong manok or sardines. Does it not sound more like a short run problem and a long run problem?
In this case Mang Pandoy has to choose between the short-run happiness of his family and the long-run financial stability of his family. Their 250 pesos they may spend on lechong manok can also be Junior’s ( Mang Pandoy’s 7th son) school supply allowance. It can also be their monthly electric bill.
But Mang Pandoy is not very fond of weighing his economic options and chooses to make his family happy for the night and goes ahead to buy lechong manok. Mang Pandoy’s family is satisfied for the mean time. And have I told you of Mang Pandoy’s philosophy that “life is short”? His short run benefits have more value to him. But it does not necessarily mean that he chose the lesser option.
Junior might be motivated because of his father’s good intentions and gets high marks in school, gets a scholarship and graduates a cum laude. These unforeseen events are what we may call externalities. They are things of which we have no control over, but are consequences of our economic decisions.
Junior gets a good job working abroad. He sends his brothers and sisters to school. They all graduate and Mang Pandoy and his family is better off economically. And all these because of the day they ate lechong manok.
To identify one by one the usefulness of economics
First things first, what is Economics really? Surely it must be something more than a course to take in college, something more than what determines the poorness and richness of a country. It is more than a social science with its many theories, and certainly more than supply and demand. Economics is a way of life. We live it in our everyday lives.
Going back to the basics, history has its own definition of what economics is. The term economics comes from the ancient Greek word oikonomos (οἰκονομία), oikos meaning household and nomos which means law, putting them together we come up with household law or law of the household. Households are the smallest units of our economy and laws are fundamental regulations imposed on us by society. Wait, does that not sound too simplistic? No. As a matter of fact households represent a fundamental aspect of the economy, inasmuch as they are economies themselves.
Are these households the very same residential areas we live in? The answer to that question is a very loud YES! Day in and day out people make economic choices on many categories in life and most of the decision-making begins at home. What shampoo to use? How many kilos of pork to consume? What type of refrigerator to invest in? Buy a Plasma TV, or a Regular one? Spend millions on a sports car or buy a smart car? The list goes on. These many little decisions, insignificant as they seem, have an impact on the overall economy. It may not be obvious to the normal person but through the trainedl eyes of an economist, these details come to life.
If economic decisions do in fact occur in every household, then it is also true that every person “out there” makes economic decisions on a daily basis. The fact that a person has money and spends it or either saves it contributes to the whole of the economy. He or she does not have known any complicated economic theories. He or she does not even have to have an economic degree of any kind.
Remembering Mang Pandoy
Mang Pandoy was our normal Filipino masa. He was unaware of any economic theories. Oblivious to the ups and downs of the economy, and yet he suffers from every economic woe and rejoices at every economic gain. Put simply, everyone who lives in this world is affected by the economy. The same thing can be said in another way: anyone who lives in this world performs economic decisions knowingly or unknowingly.
