Why PPC is also called transformation curve?

 PPC- Transformation Curve... 

PPC is also called transformation curve because it shows the nature of transformation of one commodity into other with the shift of resources from one use to others. Production with given resources and technology are being fully utilized and employed. The combination of two commodities produced can lie anywhere on the PPC but inside and outside it as shown in the following figure:


    In the above figure, point ‘H' lies below the PPC is inefficient because the available resources and technology aren’t fully utilized. Similarly point ‘G' lie above the PPC is unattainable due to limited stocks of resources and technology.

Comparison between the Marshall and Robbins definition of economics...

 Marshall defined economics as a science of material welfare. It emphasized on human welfare through the attainment and use of the material requisites of well-being. On the other hand, Robbins's definition of economics as a science of scarcity and choice emphasized on maximum satisfaction while satisfying unlimited wants through limited means which have alternative uses. From intensive analysis of these two definitions, we find the following similarities and dis-similarities:- Similarities.....  1. Study of human efforts : Both Marshall and Robbins considered economics as the study of human behavior or efforts for the material welfare of human beings or maximum satisfaction of human beings.  2 . Study of rational man: Both definitions are based on the assumption of rational man. The function of attaining and using material things for welfare of human beings in Marshall's definition and maximizing satisfaction through the scarce resources in Robbins's definition can be achie

Adam Smith Definition of Economics

 Adam Smith's definition of Economics...  Adam Smith, founder of modern economics and the leader of classical economists developed economics as a separate social science. So he is regarded as a father of Modern Economics. He wrote a book on the subject named " An Enquiry into the Nature and Causes of the Wealth of the Nations " which was published in 1776AD.

 Definition of Demand... In common language, demand is same as desire. But in economics, demand means effective desire which is supported by ability to pay and willingness to pay for goods and services. For example: if a poor person wanted to have an iPhone, it’s just his/her desire because he/she doesn’t have ability to pay for iPhone. Similarly, if a rich person wanted to buy an iPhone , it may be a demand because he/she has ability to pay for iPhone. To have a complete definition of demand, the price per unit of a commodity and the period of time in which quantity is being demanded should be clearly stated. Therefore, demand means desire, ability to pay and willingness to pay for goods and services at certain price during a certain period of time. According to Benham, “The demand for anything at a given price is the amount of it, which will be bought per unit for time at that price”. Thus demand for a commodity is defined as a schedule which shows various amounts of that commodi

Difference between movement along the demand curve and Shift in demand curve

Image
  Difference between movement along the demand curve and Shift in demand curve....  The main difference between movement along the demand curve and Shift in demand curve are as given below: 1. When the commodity experience change in both the quantity demanded and price, causing the curve to move in specific direction, is known as movement along the demand curve. But when the price of a commodity remains constant but there is a change in quantity demanded due to some other factors, causing the curve to shift in a particular side, it is called Shift in demand curve.  2. Movement in demand curve occurs along the curve, whereas the shift in demand curve changes its position due to change in original demand relationship.  3. Price is the main determinant of movement along the demand curve whereas other factors except price are the determinant of shift in demand curve.  4. Movement along the demand curve indicates the change in quantity demanded whereas Shift in demand curve indicates the ch
