30
What is world price?
Price at which the good can be bought or sold abroad
31
What price will market go to when open to trade?
Competition among importers or exporters drives the domestic price to equality with the world price
32
If world price < domestic price?
Trade leads to imports and a fall in the domestic price towards the world price
33
What are effects of imports?
Net benefits increase for importing country: There are overall gains from trade because consumer gains exceed the producer losses
34
Who are the winners of imports?
Price to domestic consumers falls
35
Who are the losers of imports?
Price received by domestic suppliers falls Demand for workers in domestic industry drops, reduces wages to domestic workers in those industries
36
If world price > domestic price?
Trade leads to exports and a rise in the domestic price
37
What are the effects of exports?
Net benefits increase for exporting country: There are overall gains from trade because producer gains exceed the consumer losses
38
Who are the winners from export
Price received by domestic suppliers increases Demand for workers in domestic industry increases, increases wage to domestic workers in those industries
39
Who are the losers from export
Price paid by domestic consumers increases
40
What is free trade?
When the government does not attempt either to reduce or to increase the levels of exports and imports that occur naturally as a result of supply and demand
41
What is a tariff?
A tax levied on imports
42
How do tariffs affect price?
They raise the domestic price above the world price, leading to a fall in trade and total consumption and a rise in domestic production
43
Who are the winners from a tariff?
Domestic producers and the government gain, but consumer losses more than offset this gain, leading to deadweight loss

64
What are Long-Run Time Horizons
