6 Outputs and Prices in GALA LAND 3. Gala Land produces three final goods: bread,water, and fruit. The table [right] shows thisyear’s output and price for each good.(a) Calculate this year’s nominal GDP.(b) Assume that in Gala Land the GDP deflator [GDP price index) is 100 in the baseyear and 150 this year. Calculate the following.(i) The inflation rate, expressed as a percentage, between the base year & this year.(ii) This year’s real GDP(c) Since the base year, workers have received a 20% increase in their nominal wages.If workers face the same inflation that you calculated in part (b)(i), what hashappened to their real wages? Explain.(d) If the GDP deflator in Gala Land increases unexpectedly, would a borrower with afixed-interest-rate loan be better off or worse off? Explain.FRQ [Form B]Outputs and Prices in GALA LANDThis Year’s Output This Year’s Price400 loaves of bread $6 per loaf1,000 gallons of water $2 per gallon800 pieces of fruit $2 per pieceAnswer to 3. (a): 400x$6=$2,400; 1,000x$2=$2,000;and 800x$2 = $1,600 for a Nominal GDP of $6,000.Answer to 3. (b) (i):Change/Original x 100; therefore 50/100 x 100 = 50% inflation rate.Answer to 3. (b) (ii):Nominal GDP/GDP deflator x 100 = Real GDP; $6,000/150 X 100 = Real GDP of $4,000.Answer to 3. (c): Inflation between these years has increased 50%; wages have increasedonly 20%; therefore workers real wages or real purchasing power has decreased.Answer to 3. (d): The borrower has borrowed “dear” money but is paying back “cheaper” money. He is better off because he is paying back money that isn’t worth what it was when he took out the loan.
