# Stumped? Get a Hint for Solving the Problem

• charlies1902
In summary, the conversation discusses a problem involving a Leontief model and the question of whether it is acceptable for cii to be greater than 1 for some i. The problem asks for both mathematical and real-world reasons for this. The speaker is unsure of how to answer the question but suggests that numbers greater than one may be allowed along the diagonal.

I attached the problem.

I honestly have no idea how to even go about solving this problem. If someone can give me a hint, that'd be great.

Start by understanding what the problem is saying. You have a Leontief model of the form
$$\textbf{x} = C \textbf{x} + \textbf{d},$$
where d is external demand and C is the inter-sector internal demand matrix. The question is asking if it is OK to have cii > 1 for some i, and if not, why not.
It asks for both mathematical and real-world reasons.
