1. In the context of Production Functions, when the Elasticity of Substitution (σ) is constant and equal to 1, the function is known as:

• Leontief Function
• Cobb-Douglas Function
• CES Production Function
• Linear Production Function

Answer: B. Cobb-Douglas specifically exhibits a constant elasticity of substitution equal to unity (1).

2. (PYQ 2021) The 'Law of Equi-marginal Returns' is primarily used to determine:
