True or false and then EXPLAIN why. Assume the economy produces five goods. If the prices of three of the goods increase, then the price level must increase.

The correct answer is False.

Explanation:

The prices of goods and services are fundamentally determined by their demand and supply. When they increase or decrease, it is because one of these two variables has led to a change. Specifically, an increase in prices occurs especially for three reasons.

Case 1: Supply is maintained and demand increases :

In this situation, companies continue to offer the same amount of a good or service, but we all buy more of them. This can happen for many reasons, among them, an increase in the population (there are more people and more traffic jams and more bikes are sold for circulation on the urban road), it becomes somewhat fashionable, our incomes increase, etc.

It can also happen that the price of a substitute rises (goods that give us exactly the same, such as orange soft drinks of one brand or another). If the price of brand X increases, the demand for brand Y will surely increase, since it will cover the same need at a lower price.

Case 2: Supply falls and demand remains :

A reduction in the supply of companies will make it more expensive. It can happen for a wide range of reasons: from the number of companies with these offers decreasing until the technology of some firms becomes outdated and only a few remain on the market. It may also happen that the price of inputs increases and that manufacturers cannot produce the same quantity as before due to this increase in price.

Case 3: Supply falls and demand increases :

In this case, a ‘mix’ of the phenomena that we have seen previously would take place. However, there are other more specific variables that cause prices to vary. For example, on occasion, governments artificially increase their monetary base. In other words, they use the strategy of manufacturing and issuing money, with more money in circulation than an economy really needs.
