Explanation:

In a market economy, most businesses have most of the resources available to them such as labor, land, and capital. They make use of voluntary decisions, that are made in their own self-interest, to achieve the highest personal benefit from various marketplace activities and transactions.

Self-interest dominate in capitalist economies where goods and services are exchanged with ease. These forces are responsible for driving the supply and demand for goods and services as well as the value of goods and services.

Adam Smith was one of the first economists to explain how self-interest and rational self-interest in a free-market economy can result to the entire economic well-being.

cognitive overload: having a lot on your mind impairs decision-making and tends to result in the simplest, but not necessarily best, option being selected.

empathy gaps: overlooking how you might feel in a different situation can result in unnecessary purchases, such as overbuying when shopping for food on an empty stomach.

optimism and overconfidence: wearing rose-tinted glasses and having unrealistic expectations about the future can affect money management and leave you unprepared for a change in circumstance.

instant gratification: seeking instant gratification drives impulsive spending and can undermine long-term planning and savings.

harmful habits: automatic or mindless behaviour can amplify a poor financial decision as it becomes a recurring event.

social norms: we are heavily influenced by the actions of others; while this can be in certain circumstances, it also contributes to the pressure to keep up with the joneses through conspicuous consumption.
