Part 1: going from no-trade to trade at world prices P S consumers add consumption, and gainG+H+I+J A Ps=100 D E B C F Pe=200 H G K producersreduce outputand loseG+H I J Pw=100 L N O M D Q Efficiency gain is I + J, Therefore efficiency loss of autarky is -(I+J)
Part 2: going from no-trade to export subsidy P S consumers face higherprices and lose-(B+C) A Ps=100 D E B C F Pe=200 H G K producersincrease outputand gainB+C+D+E I J Pw=100 L N O M D Q Export subsidy costs –(C+D+E+F) Therefore efficiency loss is –(C + F)
Combining: going from world price to export subsidy P S A Ps=100 D E B C F Pe=200 H G K I J Pw=100 L N O M D Q Combined efficiency loss is –(C + F + I + J)
