Identify the appropriate macroeconomic concepts to explain the measurement and determination of national income?

Macro Economics is a branch of economics that deals with the performance, structure, and behavior of a national or regional economy as a whole. Along with microeconomics, macroeconomics is one of the two most general fields in economics. Macroeconomic is a contribution of various economic factors such as total employment, exchange, productivity, income, wealth, inflation, interest rate, balance of payments, monetary policy, savings, investment, international trade and international finance. In contrast, microeconomics is primarily focused on the actions of individual agents, such as firms and consumers, and how their behavior determines prices and quantities in specific markets.
