Give meaning of increasing returns to a factor.
Increasing returns to a factor occur when TP increases at an increasing rate, i.e., MP rises.
Explain the reasons for : (i) increasing returns to a factor and (ii) increasing returns to scale.
Returns to a factor refers to the resultant increase in the total product when only one factor is increased, keeping all the other factors constant.
Giving reasons, state whether the following statements are true or false: (i) Average product will increase only when marginal product increases. (ii) Under diminishing returns to a factor, total product continues to increase until marginal product reaches zero.
