Veganstan's neighbouring country, Beefland. can produce and sell unlimited quantities of broccoli at 0.5$ per kilogram which happens to be also the world price PW for broccoli. 4: Assume that there is free trade between Veganstan and Beefland. For Veganstan: a) graphically show the free trade equilibrium price P'"r and quantity OFF; 2 b) briefly discuss how PFT and QFT compare to PCE and 005; c) discuss the welfare implications3 of free trade relative to the closed economy. 5: Assume that while allowing trade with Beefland, Veganstan's policy makers place a tariff of 0.5$ per kg on all broccoli imported from Beefland. For Veganstan: a) graphically show the post tariff equilibrium price PT and quantity QT; b) briefly discuss how PT and QT compare to P"T and Q\"; c) discuss the welfare implications of the tariff relat.ive to free trade. 6: Assume that while allowing for free trade with Beefland. Veganstan's policy makers decide to give to all broccoli producers in Veganstan a subsidy of 0.5 $ per kg produced. For Veganstan: a) graphically show the post subsidy equilibrium price PS and quantity 05; b) briefly discuss how P5 and 05 compare to PFr and QFT; c) discuss the effect of the subsidy on the quantity of broccoli that is being supplied domestically, as well as on the quantity that is being imported from Beefland; d) discuss the welfare implications of the subsidy relative to free trade. 7: For this question only, we assume that cauliflower is a substitute for broccoli. 1 Both demand and supply are expressed in kilograms (kg). and all prices are in dollars ($). 2 By \"graphically show", we mean that you should use the demand and supply graph/diagram analisys. 3 Recall that by \"welfare implications\" we mean: consumer surplus. producer surplus, deadweight loss. and overall welfare (including e.g. tax revenue or subsidy costs, if relevant)
