Definitions [2]
Definitions: Microeconomics
- Kenneth Boulding: "Microeconomics is the study of particular firms, particular households, individual prices, wages, incomes, individual industries, and particular commodities."
- Maurice Dobb: “Microeconomics is, in fact, a microscopic study of the economy.”
- Prof. A. P. Lerner: "Microeconomics consists of looking at the economy through a microscope, as it were, to see how the millions of cells in the body of the economy-the individuals or households as consumers and individuals or firms as producers–play their part in the working of the whole economic organism."
- "Micro-economics theory explains the composition or allocation of total production, why more of some things are produced than of others." — Watson
- "Micro economics is concerned with economic activities of economic units as consumers, resource owners and business firms." — Leftwitch
- "Micro economics deals with small parts of the economy." — Shapiro
Definition: Macroeconomics
- Kenneth Boulding: "Macro Economics deals not with individual quantities as such but with the aggregates of these quantities, not with the individual incomes but with the national income, not with individual prices but with the general price level, not with individual output but with the national output."
- J.L. Hansen: "Macroeconomics is that branch of economics which considers the relationship between large aggregates such as the volume of employment, total amount of savings, investment, national income, etc."
- Prof Carl Shapiro: "Macroeconomics deals with the functioning of the economy as a whole."
- Gardner Ackley: "Macroeconomics concerns itself with such variables as the aggregate volume of the output of any economy, within the extent to which its resources are employed with the size of the national income, with the general price level."
