If a firm uses n inputs (n > 2), what inequality does the theory of

revealed cost minimization imply about changes in factor prices (Awi) and the changes in factor demands (Axi) for a given level of output?

The theory of revealed cost minimization implies that the sum of the changes in factor demands (Axi) must be greater than or equal to the sum of the changes in factor prices (Awi). This is because the firm will always seek to minimize its costs by adjusting the factor demands in response to changes in factor prices.

How is it statistically possible that within the last 45 minutes or so,

9 out of the 10 questions are asked by the same person called
Evaristi Paulo, the answers appears immediately, and none of the answers
are questioned by Evaristi?

Does Evaristi even look at the replies?
How about it Evaristi??
Just reply to this with a simple "hello"

Unless ..... mmmh, what do we think folks?
