3. Approach - Microeconomics is based on partial equilibrium analysis whereas macroeconomics is based on general equilibrium analysis.

4. Assumptions - Microeconomics is based on partial equilibrium. Partial equilibrium isolates an individual unit from other forces and proceeds with the assumption of 'ceteris paribus'. Macroeconomics is based on general equilibrium which assumes that everything is dependent on everything else.

5. Methods - Microeconomics uses the slicing method whereas macroeconomics uses the lumping method.

9. Theory of Distribution - Micro Theory of Distribution explains factor pricing. It explains how wages, rent, interest and profits are determined. Factor prices along with product prices determine the allocation of resources to the production of various goods. Macro Theory of Distribution explains what determines the relative aggregate shares from the total national income of the various social classes.

10. Basic Questions - Micro-Economic Theory -deals with the following basic questions. i.e., what goods shall be produced and in what quantities? How they shall be produced? How the goods and services produced shall be distributed? Whether the production of goods and their distribution for consumption is efficient. Macro-Economic Theory deals with the problem of full employment of resources, i.e., are all available resources being fully utilized? Is the economy's productive capacity increasing, i.e., problem of economic growth?
