Behind the Supply Curve: Input and costs - the Produciton function - inputs and output
7 important questions on Behind the Supply Curve: Input and costs - the Produciton function - inputs and output
What do we call an input whose quantity cannot be changed for a period of time? For example?
- an input that cannot be changed in the long run is a fixed input.
unable to increase land size.
What do we call inputs whose quantity can vary at any time? Example?
able to employ or layoff
What do we call it when the quantity of output a firm produces depend on the quantity of variable inputs for a given production technology.
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What are diminishing returns to an input? And what is the slope of the MPL curve?
- each successive input will raise production by less than the last if the quantity of all other inputs.
- When an increase in the quantity of that input, holding the quantity of all other inputs and technology fixed, reduces that inputs marginal product.
- due to diminishing returns to labor the MPL is negatively sloped.
How do we determine whether a quantity is fixed or variable? What are the two determinants? How do we define them
- we determine whether a quantity is fixed or variable depends on the time horizon.
- the long run: given that a long enough period of time has elapsed firms can adjust the quantity of an input.
- the short run: defined as the period during which at least ONE input is fixed
Why the total product curve upward sloping? Is the slope constant? Why?
The slope is not constant: as you move up the curve to the right, it flattens out.
Because of the quantity of output that is generated by adding one more worker diminishes
How does the TPC and MPC of the variable input shift?
The question on the page originate from the summary of the following study material:
