An economy that is divided into two sectors- manufacturing and agriculture. for each unit of output, manufacturing requires 0.6 units from agriculture and none from manufacturing. for each unit of output, agriculture requires 0.5 units from manufacturing and 0.2 units from agriculture. determine the production level needed to satisfy a final demand of 50 units for manufacturing and 30 units from agriculture.

Construct the consumption matrix for this economy, and determine what intermediate demands are created if agriculture plans to produce 50 units.

Final answer:

To find the production levels to meet a final demand in a dual sector economy, we use the Leontief input-output model and the consumption matrix. Agriculture's plan to produce 50 units requires solving a matrix equation to determine the intermediate demands for manufacturing.

Step-by-step explanation:

The question concerns the calculation of production levels in a dual sector economy, divided into manufacturing and agriculture, to meet a specific final demand. To determine the production levels needed, we must calculate the intermediate demands created by each sector using a consumption matrix.

Let's denote the manufacturing production level as M and the agriculture production level as A. According to the question, the consumption matrix is an array where manufacturing requires 0 units from itself but 0.6 units from agriculture, while agriculture requires 0.5 units from manufacturing and 0.2 units from itself for each unit of output produced. So, the consumption matrix C can be written as:

C = [[0, 0.6], [0.5, 0.2]]

The final demand is set to 50 units for manufacturing and 30 units for agriculture. The Leontief input-output model can then be used to calculate the total production levels needed to meet this final demand. The model uses the formula (I - C)^-1 * D, where I is the identity matrix and D is the vector of final demand. After calculating the inverse of (I - C), we can multiply it by D to find the total production vector.

In the case where agriculture plans to produce 50 units, we are asked to find the intermediate demands. We substitute 50 for A in the matrix equation A = CA + D to find the intermediate demands for manufacturing (M).

After performing the matrix multiplication and solving the resulting equations, we can obtain values for M and A that satisfy the given conditions.
