1)What is macro and micro economics? What are the main differences? 2)What will make the demand line shift? 3)What will make the supply line shift?

1)Macroeconomics refers to an economy's overall performance, whether on a national, regional, or global scale. In contrast, microeconomics refers to the economics branch that focuses on how individuals or consumers react to economic agents. The two types of economics have significant differences, such as; microeconomics focuses on individual markets, whereas macroeconomics deals with the economy. Microeconomics explains individual consumer behavior, whereas macroeconomics is concerned with the aggregate demand. Furthermore, microeconomics involves externalities that arise from consumption and production. In contrast, macroeconomics involves inflation and unemployment and how they affect the economy.

2)The demand line can either shift leftward or rightward depending on different factors. When the demand curve shifts leftwards, it means there is a decline in the demand, and when the demand curve shifts rightwards, it means there is a rise in the demand. Also, the factors that will shift the demand curve includes consumers' income, consumer tastes, consumer preferences, the price of the related goods, et cetera.

3)The supply line will shift when there are changes in the factors other than the own price of the product/services. These factors include a change in factor prices, natural conditions, technological progress, transport facilities, and taxes.
