Price (P) of good (-)
price goes down, quantity demand goes up
losers of trade
producers of the discontinued product and consumers of the opposite because of price increases
winners of trade
producers of the sole product and consumers of the opposite because of price reduction
absolute advantage
productivity
Market Equilibrium:
quantity supplied = quantity demanded we sell everything we want to because this is true, every buyer can find a seller
Quantity Supplied (Qs)
specific amount willing and able to sell at a specific price
Link with Reservation Price
value of what it is you are giving up, minimum amount of money a seller will sell
Future price (-)
waiting to sell for best reward
sunk costs
cost you give up regardless (money)
Inferior good (-)
ones we would buy less
Other input costs (-)
if other costs increase (other than labor), supply decreases b/c doing less
suppose the government imposes a $1 excise tax on a good, suppose further that the demand elasticity is 0.4 and the supply elasticity is 0.6. 1) what % of the tax falls on the buyers? 2) What % of the tax falls on the sellers? 3) What change in price of the good for buyers? 4) What is the change in the price do sellers receive?
(both are inelastic, less than 1) 1) Es/(Ed+Es) x 100 = 60% 2) Ed/(Ed+Es) x 100 = 40% 3) Increases by 60% of the tax, $.60 4) Decreases by 40% of tax, $.40
opportunity cost per unit table
- what you give up to make one - value: what you give up / what you get

The Method
1. Who is DIRECTLY affected? Who's going to notice the change and alter their behavior (buyer or seller) a. i.e., Who would notice the change and alter their behavior? 2. How does behavior change? More or less 3. What is the result?
If "workers in the United States are the most productive in the world," why do we consume so many imported goods?
Because they are cheap to produce, thus cheaper to sell (opportunity cost); productivity is irrelevant to the question, opportunity cost is what matters most in this situation
If "trade can make everyone better off," why is there so much opposition to it?
Everything comes with a cost, must look at both sides, be suspicious if someone is only giving you one side of a story; countries as a whole if you add up all the benefits and costs, the benefits will outweigh the costs for ALL countries as a WHOLE; there will be opposition only from those INDIVIDUALS from which the costs outweigh the benefits; we are setting policies for the country as a WHOLE; trade allows for countries to produce outside their limits
