the total benefits minus total costs flowing from a decision

what is equilibrium?

the. point where there is no tendency for change, quantity demanded equals quantity supplied

when thinking about how to create a market demand curve, first add all the quantities together at each point, then multiply by the scale, and. then plot your projection

it goes up, because even though there is a decrease in quantity demanded, there is a large increase in price, so the revenue is bigger

marginal!

what does economic surplus measure?

measures how much the decision has improved your well being

no, it means a shift ALONG the supply curve, it causes an increase or decrease in the quantity supplied

if you want less. gasoline to be produced, what should. you subsidize, diesel or gasoline? (assume diesel is a substitute in production for gasoline // subsidize means to support it by the government)

you should subsidize diesel because this means diesel is more profitable to make and the supply of gasoline will g down
