➤ What is the relationship between market share and profit maximization?
Larger market share can increase pricing power and lower average costs through economies of scale. It helps firms capture more customers, raise margins, and influence market conditions. However, market share alone does not guarantee profit maximization; firms must manage marginal cost, marginal revenue, product differentiation, and competitive responses to sustain higher profits.

➤ Why does the sum of exponents determine returns to scale in Cobb–Douglas functions?
The sum of exponents equals the degree of homogeneity. If the sum exceeds one, scaling inputs raises output more than proportionately (increasing returns); equal to one gives constant returns; less than one yields decreasing returns. This follows from scaling all inputs by the same factor and observing how output scales.
