Q

Economics as a social science (3 points)

A

The ‘social’ aspect is because economics looks at human behavior, particularly in relation to satisfying human needs and wants. Economics is also a ‘science’. This is because of the way that economists put forward and investigate theories in the same way as scientists. The theories put forward by economists are often referred to as models.
