Consider the following production possibilities frontier model for an economy that produces only two goods: barley and tablets. which of the following is true regarding this economic model? the fact that there are only two goods produced in this theoretical economy, when, in reality, economies produce many more types of goods, means this model is generally useless. this ppf is not an economic model. in order to construct such a model, an economist would need real life data regarding countries that only produce two goods. the fact that there are only two goods produced in this theoretical economy is a simplifying assumption that still allows economists to demonstrate key economic concepts.

The fact that there are only two goods produced in this theoretical economy is a simplifying assumption that still allows economists to demonstrate key economic concepts.

Explanation:

The purpose of economic models is not exactly to portray complex reality, but to produce insights into how it works. Creating a model with two countries that produce thousands of products would be methodologically unfeasible. Economists therefore adopt simplifications to explain concepts and create insights into how the real economy works.

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.
