Problem #1. Consider a three-sector economy consisting of a: construction (C) sector; manufacturing (M) sector; and transportation and warehousing (T) sector. The input-output (IO) transactions table (i.e. the Use table, billion $/year) is: 12.455 M CMTAX 0.275 491.154 1,973.767 40.425 1,026.979 T Y X 7.194 1,538.909 1,558.833 114.545 1,895.193 4,474.659 209.856 195.330 560.692 1,006.303 2,278.581 689.234 1,558.833 4,474.659 1,006.303 where X is the total output, Y is the output to final consumers, and V is the value added. For $1 billion/year production of commodity by the manufacturing (M) sector: (a) Calculate the direct requirements (overall and from each sector) in billion $/year; and (b) Calculate the total requirements (overall and from each sector) in billion $/year.
