What is the goal of producers?

Maximize profits by efficient production.

What are factors of production?

Labor and capital, including workers and machines.

Variable inputs can be easily changed, while fixed inputs are hard to change quickly.

Labor is variable, capital is fixed in the short run.

By making trade-offs between workers and machines.

Producers aim to maximize profits by efficiently utilizing labor and capital, adjusting inputs in the short run and optimizing labor-capital trade-offs in the long run, with diminishing marginal product of labor affecting production efficiency.
Returns to scale impact production quantities, not profit, with industries exhibiting either increasing or decreasing returns, influenced by factors like machinery efficiency and land limitations, emphasizing the importance of innovation and productivity in sustaining growth and standard of living.

Consumer theory has been completed, moving on to producer theory and the supply curve.
Producers aim to maximize profits by efficiently producing goods.
Producers have a production function to maximize profits by minimizing costs.
Labor and capital are factors of production, with labor being workers and capital being machines and buildings.
Inputs can be variable (easily changed) or fixed (hard to change quickly).
In the short run, labor is variable while capital is fixed.
Short run production function is q equals f of L and k bar.
Marginal product of labor is the change in output for the next unit of labor input.
Diminishing marginal product of labor occurs due to limited capital.
Long run production involves optimizing labor versus capital, making trade-offs between workers and machines.

An indifference curve represents points where individuals are indifferent, while an isoquant shows combinations of capital and labor that produce the same output.
Different combinations of capital and labor can produce the same output for a given production function.
Isoquants are combinations of inputs that yield the same level of output, following similar principles to indifference curves.
Perfectly substitutable inputs, like a Harvard graduate and a Beanie Baby, lead to linear isoquants with a slope of -1.
Perfectly non-substitutable inputs, such as a right shoe and a left shoe, result in a Leontieff production function.
The marginal rate of technical substitution is the slope of the isoquant, varying along the isoquant due to diminishing marginal products.
The MRTS is calculated as the negative ratio of the marginal product of labor to the marginal product of capital.
Returns to scale refer to the change in production when all inputs are proportionally increased or decreased.
Constant returns to scale mean doubling inputs results in double the output, while increasing returns to scale lead to more than double the output.
Increasing returns to scale can stem from firms specializing as they grow, while decreasing returns to scale may arise from coordination difficulties.

f of L is a function that doubles inputs to yield more than double the outputs.
Returns to scale refer to the quantity of product being produced, not profit.
Industries can exhibit either increasing or decreasing returns to scale.
Production of tobacco is an example of decreasing returns to scale due to limited land and crop yield.
Increasing returns to scale can be seen in industries like primary metal production with more efficient machinery and workers.
Forever increasing returns to scale would lead to a monopoly, which is unsustainable in an economy.
Productivity and innovation are crucial in increasing production with limited inputs.
Thomas Malthus predicted diminishing productivity due to fixed land leading to mass starvation, but innovation has disproved this theory.
Innovation in agriculture, like tractors and fertilizers, has significantly increased food production.
Standard of living is determined by productivity and innovation, with capital coming from savings and innovation being the key factor.

Total factor productivity measures how much productivity increases given capital and labor.
Productivity in the US grew rapidly from 1947 to 1973 at about 2.5% annually.
Productivity growth slowed from 1973 to the early 1990s to about 1% per year.
Productivity surged again from 1995 to 2005, reaching about 2.5% annually due to the IT boom.
However, productivity has since decreased to about 1.5% annually.
The distribution of productivity gains has heavily favored the top income brackets since 1973.
The question of how to spend productivity gains and who benefits from them remains crucial and raises equity and fairness concerns.
