14. Isoquants are typically: — Convex to the origin
15. Explicit costs are: — Costs that involve a direct payment of money

21. Total Cost (TC) is the sum of: — Fixed Costs and Variable Costs
22. What are the main types of costs considered in the Theory of Costs? — Total Costs, Average Costs, and Marginal Costs
23. When does the Marginal Product (MP) curve typically start to decline? — After the point where the Law of Diminishing Marginal Returns sets in
24. The Marginal Rate of Technical Substitution (MRTS) between two inputs (e.g., labor and capital) indicates: — How much capital must be reduced to increase labor by one unit while keeping output constant
25. As output increases, AFC: — Decreases
26. Economies of Scale occur when LRAC: — Decreases as output increases
27. Constant Returns to Scale occur when LRAC: — Remains constant as output increases
28. The production function shows the relationship between: — Inputs and the maximum output achievable
29. The AVC curve typically: — Is U-shaped

31. Which of the following is NOT typically considered a factor of production? — Money
32. Which of the following is a cause of economies of scale? — Increased specialization and division of labor
33. The MRTS is equal to the ratio of: — Marginal Product of Labor to Marginal Product of Capital
34. The slope of an isoquant is known as the: — Marginal Rate of Technical Substitution (MRTS)
35. Variable Costs (VC) are costs that: — Vary directly with the level of output
36. In the short run, a firm's production decisions are constrained by: — At least one fixed input
37. A Cobb-Douglas production function is often represented as Q = A * L^α * K^β. What does the sum (α + β) indicate? — The returns to scale (if α + β = 1, constant returns; >1, increasing; <1, decreasing)
38. The point of tangency between an isoquant and an isocost line represents: — Both the maximum output for a given cost and the minimum cost for a given output
39. The relationship between Marginal Product (MP) and Average Product (AP) is such that MP intersects AP at: — The maximum point of the AP curve
40. The slope of an isocost line is equal to: — The negative of the ratio of the prices of the two inputs
41. The difference between the short run and the long run in production theory is: — The ability to change all inputs
42. Marginal Cost (MC) is defined as: — The change in total cost resulting from a one-unit change in output
43. Marginal Product (MP) is defined as: — The change in total output resulting from a one-unit change in a variable input
44. The MC curve intersects the AVC and ATC curves at: — Their minimum points
45. Average Fixed Cost (AFC) is calculated as: — Fixed Cost / Quantity
46. The Law of Diminishing Marginal Returns states that as more units of a variable input are added to a fixed input, beyond a certain point: — The marginal product of the variable input will eventually decrease
47. Economic profit is calculated as: — Total Revenue - (Explicit Costs + Implicit Costs)
48. The 'break-even point' for a firm occurs where: — Total Revenue equals Total Cost (Economic Profit is zero)
49. Average Total Cost (ATC) is calculated as: — Total Cost / Quantity
50. Fixed Costs (FC) are costs that: — Do not vary with the level of output in the short run
