Building Blocks in Economics :The Problem of Choice

Economics deals with choice in the presence of limited resources and unlimited wants. It studies how individuals, enterprises, governments, and societies use scarce resources efficiently to satisfy needs and wants, and the opportunity cost of those choices.

The three key questions in economics are: what to produce, how to produce, and for whom to produce. These arise because wants are unlimited but resources are limited.

Different economic systems answer the three questions differently. In a market economy, demand and supply mainly decide resource allocation. In a planned economy, the government decides what, how, and for whom to produce. A mixed economy combines both market forces and government regulation.

I cannot know what your parents bought, but you can write any three items from this month and classify them. For example: rice — need, school bag — need, toy — want. Needs are essentials like food, water, and shelter, while wants are non-essential items like gadgets, luxury items, or entertainment.

Yes, too many wants may create problems because human wants are unlimited and keep changing, while resources are limited. If people want too many things at once, they may face shortage of money, time, and resources, and it becomes difficult to satisfy all wants. This is why choices and prioritisation are necessary.

When parents make everyday purchases, they compare needs, wants, prices, and available money. The opportunity cost of one decision is the value of the next best alternative given up. For example, if they buy a new mobile phone, the opportunity cost may be the holiday, savings, or another useful item they could have bought instead.

I spend time by first doing important tasks such as study, rest, and helping at home, and then using the remaining time for leisure. Time is a scarce resource because each day has only 24 hours, so choosing one activity means giving up time for another activity. Therefore, time also has opportunity cost.

No, the government should not completely stay out of enterprise decisions. The chapter says that even in a market economy, the government plays an important role by ensuring safety, law and order, and public goods. Some regulation is needed so that markets work fairly and resources are not misused.

One example is the government's role in providing or restricting support to an industry. From the chapter, government actions can affect industries through laws, regulations, permits, and incentives. For example, if the government encourages machinery, a sector may grow faster; if it imposes too many restrictions, it may reduce competition and innovation.

The government should allocate more funds to healthcare and education because these build human well-being and long-term development. The chapter suggests that public spending on welfare and infrastructure helps improve people's quality of life. Defence and space exploration are also important, but healthcare and education directly benefit a larger part of the population and support future growth.
