# Marginal product and cost have an inverse relationship

### Explain the Relationship Between the Marginal Product of Labor & Marginal Cost | Bizfluent

Marginal Cost shows the change in the total cost when an additional unit of There is an inverse relationship between Marginal cost and marginal product. Inverse relationship between MC & MP. MC is independent of fixed francinebavay.info fixed cost do not change with change in output there are no marginal fixed cost. The U-shape of the marginal cost curve is closely related to the hump-shape of the marginal product curve. The increasing portion of the marginal product curve .

Variable costs VC are the costs of the variable input, labor, or wL, where w is the wage rate and L is the amount of labor employed. In the short run, production can be varied only by changing the variable input.

Thus only variable costs change as output increases: At low production levels the APL tends to increase as additional labor is added. The primary reason for the increase is specialization and division of labor. Eventually the MPL reaches it maximum value at the point of diminishing returns.

## Marginal cost

Beyond this point MPL will decrease. Graphically, the APL curve can be derived from the total product curve by drawing secants from the origin that intersect cut the total product curve. The slope increases until the line reaches a point of tangency with the total product curve.

This point marks the maximum average product of labor. It also marks the point where MPL which is the slope of the total product curve [8] equals the APL the slope of the secant.

Diminishing marginal returns[ edit ] The falling MPL is due to the law of diminishing marginal returns.

The law states, "as units of one input are added with all other inputs held constant a point will be reached where the resulting additions to output will begin to decrease; that is marginal product will decline. The key factor is that the variable input is being changed while all other factors of production are being held constant. Under such circumstances diminishing marginal returns are inevitable at some level of production.

Diminishing marginal returns means that the marginal product of the variable input is falling.

To ensure that our nation's banks retain their liquidity and remain in business, the Federal Reserve System stands ready to lend bank reserves on a moment's notice to any bank. The discount rate is the interest rate the Federal Reserve System charges for these loans.

Like any interest rate, when it goes up or down it discourages or encourages borrowing. In principle, the Fed can use the discount rate to control our nation's money supply.

Deriving Marginal Revenue From the Demand Curve

The U-shape of the marginal cost curve is closely related to the hump-shape of the marginal product curve. The increasing portion of the marginal product curve corresponds with the decreasing portion of the marginal cost curve.

The decreasing portion of the marginal product curve corresponds with the increasing portion of the marginal cost curve.

### What Is the Connection between Marginal Cost and Marginal Product?

The peak of the marginal product curve corresponds with the minimum of the marginal cost curve. Because variable cost is largely associated with the cost of employing a variable input in the short runit is possible to identify a connection between the marginal cost curve and the marginal product curve.

The quantity of output in which marginal cost is at a minimum is the same quantity of output produced by the variable input when the marginal product of the variable input is at a maximum. Over the range of production in which marginal product increases and the variable input experiences increasing marginal returnsthe marginal cost curve declines.

Over the range of production in which marginal product increases and the variable input experiences decreasing marginal returns brought on by the law of diminishing marginal returnsthe marginal cost curve is rising.

The correspondence between the marginal product and marginal cost curves indicates that the law of diminishing marginal returns is the key reason for increasing marginal cost.

This further implies that the law of supply and the positively-sloped supply curve can be explained in the short run by increasing marginal cost.

## Explain the Relationship Between the Marginal Product of Labor & Marginal Cost

Marginal Cost and Marginal Product This diagram displays the marginal product and marginal cost for the production of Wacky Willy Stuffed Amigos those cute and cuddly armadillos, tarantulas, scorpions, and rattlesnakes.

The top panel presents the marginal product of the variable input used to produced Stuffed Amigos. The bottom panel contains the marginal cost of producing Stuffed Amigos. The marginal product curve in the upper panel has a distinctive hump-shape, with marginal product rising, reaching a peak, then falling.
