...e like there should be another equation for K, but nobody is giving it to me. So I'm willing to act as if it is known. He has no error terms, so the first thing I say is he needs some, and so it becomes: X_(t+1) = (1 + a) X_t + (a/K)* (X_t)^2 - g Y_t X_t +e1_t Y_(t+1) = b Y_t + h* X_t * Y_t +e2_t If he has given me what he actually intends, there is no conventional simultaneity in the econometric sense, because there is no X_t+1 or Y_t+1 on the right hand side. THere might be some seemingly unrelated regression, though, since the error terms could be autocorrelated and this would induce a...
