  8. Summary • By liberalising its beef market Europe is moving away from protectionism, so imports from Brazil increase. • This increases the total world import demand, so there is a new higher world equilibrium price and imports. • If a country is large and tries to raise its domestic price then this will depress the world price. • If a country tries to stabilise the domestic price then this will destabilise the world market price for everyone else if the country is large.
