Zero Economic Profit Example |
|
Definition
Farmer
A farmer puts down 1 million to start a farm. He could have deposited the money and made 50,000 a year or gotten a job for 30,000. So this 80,000 of implicit cost is economic loss. So if the farmer makes 1.08 million he will make zero economic profit even though he gained 80,000 dollars. |

|
|
Term
Explanation of Short Run Increase in Demand |
|
Definition
Entry and Exit of a market happens in the long run. So if something's increase occurs quickly (Oprah, health benefits etc...) the demand curve shifts right in response to greater demand. The firms will produce at a higher point on their supply curve for a higher price. In the long run more firms will enter and produce more so price will be lowered. Afterwards you'll have an increase in supply and the same price. |
|
|
Term
|
Definition
The long run supply curve is usually more elastic because of entry and exit. It has more time to respond to change in demand. |

Why Taxes create Deadweight Loss |
|
Definition
Taxes cause deadweight loss because they prevent buyers and sellers from realizing some of the gains from trade. Also people respond to incentives so people will buy at a point on the demand curve to the left of equilibrium. |
