List of top Economics Questions on Cost Function and Marginal Cost

Consider the following statements: A. Average Fixed Cost always decline with increase in output, B. Marginal Cost intersects AVC and ATC at their minimum point, C. Learning Curve implies cost rises with accumulated output, D. In the long run, all costs are variable, E. Longrun Average Cost is envelope of Shortrun Average Cost curves.

If the marginal cost of a firm is given as the function of output, \( C'(Q) = 2e^{0.2Q} \), and if the fixed cost is 75, find the total cost function.

Let the total cost (TC) = \( C = f(X) \) for a firm in the short run, which of the following expressions represents the correct relationship between marginal cost (MC) and average cost (AC)?

On the basis of the data given below for an imaginary economy, estimate the value of Net Domestic Product at Factor Cost (\(NDP_{FC}\)): \[ \begin{array}{|l|l|l|} \hline \textbf{S. No.} & \textbf{Items} & \textbf{Amount (in ₹ crore)} \\ \hline (i) & \text{Gross Domestic Fixed Capital Formation} & 300 \\ (ii) & \text{Exports} & 70 \\ (iii) & \text{Government Final Consumption Expenditure} & 400 \\ (iv) & \text{Consumption of Fixed Capital} & 50 \\ (v) & \text{Household Final Consumption Expenditure} & 590 \\ (vi) & \text{Inventory Investment (Net)} & -60 \\ (vii) & \text{Imports} & 80 \\ (viii) & \text{Net Indirect Taxes} & 50 \\ (ix) & \text{Net Factor Income from Abroad} & 40 \\ \hline \end{array} \]

“Accommodating transactions are undertaken to maintain stability in the Balance of Payments Account.”
Justify the given statement with a valid explanation.

Given a cubic cost function C(Q) = Q³ + Q² + Q + 1, arrange total cost (TC), Marginal Cost (MC), Average Cost (AC), Average Fixed Cost (AFC) in increasing order when Q = 2.
(a) AFC
(b) TC
(c) MC
(d) AC

For a manufacturing firm, the cost function is given by \(C = q^{3} + 2q^{2} + q + 1.\) The marginal and average costs at \(q = 10\) units are respectively given by:
