A mathematical connection between marginal product and total product stating that marginal product IS the slope of the total product curve. If the total product. What is the relationship between the total product and the marginal product. It is discussed followed by practice exercises to complete one. Total, Average and Marginal. Products. • The Total Product Curve shows the maximum output attainable from a given amount of a fixed input (capital).

So this tells us that, for example, let's say we have three employees, that on average each employee is producing If we were to graph it-- again, your average is this curve right here-- it goes up at first and then falls, just as marginal went up and then fell like that.

Let's talk about actually these two curves and how they're related to one another. So here, where the marginal lies above the average, that would be from here to the left.

The marginal is up above the average. Notice how it's pulling the average up. If I were to use a sports analogy-- I think that actually helps before I go into this specific example-- If I were to use a sports analogy, let's say that a quarterback has a certain average. Let's say we're talking about his average touchdown passes per game.

And let's say that his average right now is, on average, he's passing two. So he has two average touchdown passes per game. That would be, obviously, this curve-- his average.

The marginal represents his next game, his next performance. Because marginal means your additional thing. So if, in the next game, he has a really great game and he has, let's say, five touchdown passes, won't that bring his average of two up?

That's what's going on here. So with marginal and average product of labor, when we're here, to the left of this spot, adding another worker, one more, will add more than the average to output. So we'll pull that average up. As soon as that quarterback now has a really bad game, his marginal performance let's say is 0 touchdown passes, that's going to pull his average down.

And that's where the marginal lies below the average. So where a marginal lies below the average, it's going to pull it down. And that would mean that adding another worker will add less than the average to output. It doesn't mean necessarily that they're going to bring overall output down, it just means that they're going to add less than the average to output.

And that brings us to a concept called diminishing marginal product, which says that the marginal product of capital or labor will begin to fall at some point, holding everything else constant. So right here-- I said I would be talking to you about why the curves were shaped the way that they are.

Notice how total product is increasing except when we hire the sixth employee. But it's increasing at different rates, and that's what marginal product measures. It measures the rate at which total product is changing. And at first-- look at how the second employee, what he adds to the firm. He adds actually more than even the first worker. Why would that be? Well if you think about it, specialization can kind of explain that. With two people, can't you get so much more done than with just one person?

But remember, in the short run, there's a fixed input. And so there's fixed amount of stuff for these workers to work with.

So at some point-- I just have it set in pretty quickly here to prove my point-- but at some point, specialization kind of runs out. And yeah, hiring more workers is still going to help you produce more. As long as the marginal product of a worker is greater than the average product, computed by taking the total product divided by the number of workers, the average product will rise.

For students, it is often easiest to remember when you think about your grade point average. But if your g. Thus the marginal product will always intersect the average product at the maximum average product. There may even come a point where adding an additional worker makes things so crowded that total product begins to fall. In this case the marginal product is negative. In our example, adding the ninth and tenth worker yields lower output than what was produced with only eight workers.

So how many workers should be employed?

We know that we would not stop in the region where marginal product is increasing and we would not produce in the region where marginal product is negative. Thus we will produce where marginal product is decreasing but positive, but without looking at the costs and the price that the output sells for, we are unable to determine how many workers to employ.

A production function shows the output or total product as more of the variable input, in our case labor is added. The function shows the regions of increasing marginal product, decreasing marginal product, and negative marginal product. Practice Residential construction crews are often three to eight people depending on the type of work.

Think of what factors would cause increasing and decreasing marginal productivity in construction. Think of another industry and what would be the ideal number of workers? Key Equations Section Short Run Costs Accounting vs. Economics Recall that explicit costs are out-of-pocket expenses, such as payments for rent and utilities, and implicit costs reflect the opportunity costs of not employing the resource in the next best option. A mathematical connection between marginal product and total product stating that marginal product IS the slope of the total product curve.

If the total product curve has a positive slope that is, is upward slopingthen marginal product is positive. If the total product curve has a negative slope downward slopingthen marginal product is negative. If the total product curve has a zero slope horizontalthen marginal product is zero.

The relation between total product and marginal product is one of several that reflect the general relation between a total and the corresponding marginal. There general relation is this: A marginal is the slope of the total curve. Marginal is another term for slope.
