Study Notes
Introduction to Production
- Economics previously focused on consumer demand.
- This section introduces the supply side, focusing on production.
Production Functions
- Firms produce a single good.
- Two main inputs: labor (workers) and capital (buildings, machinery, tools).
- Production function describes how inputs combine to produce output (Q = F(K,L)).
- Unlike utility functions, production functions have physical meaning (e.g., producing 100 apples).
- Transformations of the function aren't permitted without impacting the meaning.
-
Returns to Scale:
- Increasing: Output more than doubles when inputs double.
- Constant: Output doubles when inputs double.
- Decreasing: Output less than doubles when inputs double.
Marginal Product
- The marginal product of capital (MPK) measures additional output from one more unit of capital, holding labor constant.
- The marginal product of labor (MPL) measures additional output from one more worker, holding capital constant.
- As capital increases with labor held constant, MPK tends to fall (diminishing returns). The same logic applies to additional labor.
Marginal Rate of Technical Substitution (MRTS)
- The MRTS measures the rate at which one input can be substituted for another while maintaining a constant output level.
- MRTS = MPL/MPK. This ratio indicates the relative productivity of labor and capital.
- A constant MRTS suggests a constant rate of substitution between inputs.
Isoquants
- Isoquants are similar to indifference curves in consumer theory.
- Isoquants show all possible combinations of inputs (K and L) that produce a specific level of output (Q).
- The slope of an isoquant represents the MRTS (negative of MRTS).
