Answer:
price-level surprises
Explanation:
Price can be defined as the amount of money that is required to be paid by a buyer (customer) to a seller (producer) in order to acquire goods and services. Thus, it refers to the amount of money a customer or consumer buying goods and services are willing to pay for the goods and services being offered. Also, the price of goods and services are primarily being set by the seller or service provider.
In sales and marketing, pricing of products is considered to be an essential element of a business firm's marketing mix because place, promotion and product largely depends on it.
The rational expectations theory (RET) is an economic theory which states that consumers would always make decisions based on the best information that is made available to them at a given time.
According to rational expectations theory (RET), unanticipated changes in the price level, or price-level surprises would cause temporary changes in real output. Thus, macroeconomic policy such as price level, economic growth, Gross Domestic Product (GDP), inflation, unemployment and national income levels are ineffective in both the short run and long run
