  • Production “Production is the process of converting raw material into useful thing”.
  • Saving It is the part of income which is not consumed. It is an art of abstinence from consumption.
  • Investment It is expenditure by the producers on the purchase of such assets which help to generate income.
  • Economic Activity It is an activity which is related to the use of scarce means. Means are always scarce in relation to our wants.
