Which best describes the purpose served by economic models within an economic system?

The first answer is correct (A).

The theoretical models of economics are characterized by producing insights about the real functioning of the economy. In this way, a well-adjusted model identifies the patterns of functioning of economies, such as economic cycles and the expectation reversion aspects of economic agents and crises.

However, no model has the ability to control any economic aggregate. The models serve for the authorities to get ahead of economic events and make efficient decisions according to their objectives. For example, stimulating the economy, curbing inflation or avoiding crises.
