Exercises 1-4 refer to an economy that is divided into three
sectors-manufacturing, agriculture, and services. For each unit
of output, manufacturing requires .10 unit from other companies
in that sector, .30 unit from agriculture, and .30 unit from services.
For each unit of output, agriculture uses .20 unit of its own output,
.60 unit from manufacturing, and .10 unit from services. For each
unit of output, the services sector consumes .10 unit from services,
.60 unit from manufacturing, but no agricultural products.
1. Construct the consumption matrix for this economy, and de-
termine what intermediate demands are created if agriculture
plans to produce 100 units.
2. Determine the production levels needed to satisfy a final
demand of 18 units for agriculture, with no final demand for
the other sectors. (Do not compute an inverse matrix.)
3. Determine the production levels needed to satisfy a final
demand of 18 units for manufacturing, with no final demand
for the other sectors. (Do not compute an inverse matrix.)
4. Determine the production levels needed to satisfy a final de-
mand of 18 units for manufacturing, 18 units for agriculture,
and 0 units for services.
