What is supply and demand

Explanation:

Supply and demand should be thought of together. Suppose you need a hairbrush. You go to your local pharmacy and ask one of the clerks if they stock hairbrushes. They say no they don't. If the pharmacy is supposed to have hairbrushes and they don't, then the supply side does not meet the demand. That's too little supply.

So next you try the nearest grocery store and they say "Yes. For you it's $2.99."

Now you represent the demand, and the store represents supply. They have the hairbrush you want. But the store won't stock hairbrushes if in the last year, you are their first customer who wanted a hairbrush. You still provide the demand, but there is no supplier. So you go without a hairbrush.

The same thing can happen to the supply side. The store has 25 hairbrushes. You only want one. There are too many brushes on the supply side. The store, if they do that with everything, will go broke. Too much supply is just as bad as not enough.

levels of production can be increased by technology while holding labor and capital constant, because increased technology makes the production process more efficient. subsequently, the lras curve is almost a vertical line, that can shift to the right, with an increase in technology.

the relationship between the lras curve and the ppc is that both can make the economy could grow. the ppc achieves that when it shifts outward because of more resources or technological advances while the lras curve shifts if more resources are developed or if there are technological advances.

the lras curve is a vertical line at an output level that represents the number of goods and services a nation can produce over a sustained period using all of its productive resources as efficiently as possible with all of the current technology available to it.

the production possibilities frontier (ppf) is a graphical device that is used for economic analysis of production decisions because the ppf measures the maximum possible combinations of two goods that an economy is capable of producing with its currently available resources and technology.
