# The flows in an economic input-output model are as follows: x 11 = 50, x 12 = 50, x 21

## Question:

The flows in an economic input-output model are as follows: x_{11} = 50, x_{12} = 50, x_{21} = 30, x_{22}=0, ƒ_{1}= 10, ƒ_{2} = 25.

1. Determine the input-output model for this network. You need to derive two equations in terms of the throughput and final demand from each sector.

2. For the given flows, sector 1 extracts crude oil and emits 5 m^{3} of SO_{2}. Sector 2 transports crude oil and emits 8 m^{3} of SO_{2}. Determine the life cycle emission of SO for delivering $10,000 worth of crude oil.
