Economics · Production and Costs
Consider the production function q = f(x1, x2) where a firm produces q amount of output using x1 amount of factor 1 and x2 amount of factor 2. If the firm increases both factors by a factor t (where t > 1), identify the condition representing decreasing returns to scale:
- 1f(t x1, t x2) > t × f(x1, x2)
- 2f(t x1, t x2) < t × f(x1, x2)✓
- 3f(t x1, t x2) = t × f(x1, x2)
- 4f(t x1, t x2) = f(x1, x2)
Correct answer
f(t x1, t x2) < t × f(x1, x2)
