Together, they accounted for more than 30 percent of the world's total gross national product.

When we examine the reproduction of the total social product, however, other problems emerge.

Finally, we need an equation that determines the total product of an economy.

It makes up the total gross domestic product of Britain.

If that rate were to continue to 2030, the total product would be more than twice what it is now, precisely 121.6 percent higher.

So the increase of total product would be almost 100 percentage points more than the increase in population.

Under the latest European proposal, such items would amount to no more than 8 percent of total agricultural products.

The output is relatively high, at 2.6% of the total product.

Up until this point every additional unit has been adding more value to the total product than the previous one.

Therefore the total product starts to decrease at this point.
