Production Costs

When looking at productivity what is the relationship between TPL and MPL?

When the total product of labor is increasing, the marginal product of labor remains positive, but when the total product of labor is falling, the marginal product of labor becomes negative.

What is the difference between the short run (SR) and long run (LR) for a business from a microeconomics standpoint?

The short run is a period when the quantity of a single or more inputs does not vary and the quantities of the other inputs vary or can be varied. Contrary to this, the long run is a period when the amounts of all inputs can vary. The difference between these concepts entirely depends on how many inputs that affect production vary or the number of fixed inputs.

What will be some fixed cost and variable costs associated with producing an album?

Fixed costs of producing an album include rehearsal space, album artwork, gear. Variable costs include studio sessions, sound engineer, mixing and mastering, studio time, and publicity.

Where does the Law of Diminishing Returns sets in?

The law of diminishing returns sets in when an input value increases to a point where the marginal increase in outputs starts to diminish with all other factors held constant. The law sets in at a point where the effect of each additional until is to decrease output.
