Chapter 5: Production

Technology of Production: Combines inputs (production factors) to create output.
Production with one variable input (Labour): Shows how output changes with varying labor input while holding other inputs constant. Analysis focuses on total product, average product, and marginal product of labor.
Production with two variable inputs (Labor, Capital): Examines production with both labor and capital as variable inputs, showing substitution possibilities between them and creating isoquants.
Technical Progress: Improvements in technology increase output for the same input combinations.

Introduction to the Theory of the Firm

Supply Side of the Market: Focuses on the firm's production decisions and cost variations with output.
Cost-Minimizing Production Decisions: Examines how firms choose the least costly input combinations to achieve a given output level.
Cost Variation with Output: Analyzes how a firm's costs change as its output level increases or decreases.

The Technology of Production

Production: Combination of inputs to produce output.
Categories of Inputs (Production Factors):
- Labour
- Raw materials
- Capital (which can include oil, land, and tools).

The Production Function

Production Function: Mathematical relationship showing the maximum output possible from a given combination of inputs.
Technical Feasibility: Describes what is currently technically achievable using current technology to obtain maximum output from input combinations.

Production with one variable input (Labour)

Data Table (Example Chart): Shows the relationship among the variables, and includes columns for Amount of Labor (L), Amount of Capital (K), total Output (Q), Average Product (AP), and Marginal Product (MP).
Average Product (AP): Output per unit of labor input = Q/L
Marginal Product (MP): Change in output resulting from a one-unit increase in labor while holding other inputs constant.
Law of Diminishing Marginal Returns: As more of a variable input (e.g., labor) is used with a fixed supply of other inputs, the extra output from each additional unit of the variable input eventually decreases.
Graph of Total Product (Q), Average Product (AP), and Marginal Product (MP) of labor. Showing how the Average (AP) and Marginal Product (MP) curves change with labor input.
Output increases at first, reaches a maximum and decreases. Average Product of Labour initially increases, reaches maximum, then decreases. Marginal Product initially increases rapidly, then decreases and eventually becomes negative.

Malthus and the Food Crisis

Thomas Malthus: Economist who predicted mass hunger due to diminishing marginal returns in agriculture.
Malthus's Theory: Population growth outpaces food production due to limited land and diminishing marginal returns in agriculture.
Counterarguments: Technological progress and improved farming techniques can offset diminishing returns, increasing food production.
Data: Chart of net food production per capita from 1961 to 2014. Demonstrates that food production has generally outpaced population growth. Shows how food production has kept up with population growth over time due to technological improvements.

The Effect of Technological Improvement

Technological Improvements: Advancements in technology increase productivity of inputs. This allows output to increase even when the underlying production function exhibits diminishing returns of any one input.

Production with Two Variable Inputs (L,K)

Substitution Among Production Factors: Managers of businesses make choices among different possible combinations of capital and labour.
Trade-offs: Input combinations must be determined using a trade-off between the two.
Flexibility of Inputs: Producers can react to changes in input market conditions.
Isoquant Maps: Show curves that indicate different output combinations of capital and labor that yield the same level of output.
Marginal Rate of Technical Substitution (MRTS): Rate at which one input can be substituted for another while maintaining a constant level of output.
Diminishing MRTS: The rate at which on input can be substituted for another decreases as more of that input is used.

Isoquants When Inputs are Perfect Substitutes

Constant MRTS: The rate at which one input can be substituted for another does not change.
Isoquant Shape: Straight lines, indicating perfect substitutability.

Fixed-Proportions Production Function

Fixed Proportions: Inputs must be used in a fixed ratio.
Isoquant Shape (example): L shape, indicating that inputs cannot be substituted.
Substitution Impossibility: Inputs must be combined in a certain proportion for any specific level of output.
