In simultaneous equations models, dependent variables are functions of other dependent variables. Thus some of the explanatory variables are jointly determined with the dependent variable. For instance, in the simple model of supply and demand, price and quantity are jointly determined.

### In the supply demand model $Q_s=a_0+a_1P+u$ and $Q_d=b_0+b_1P+b_2Y+v$, is it true that $a_0,a_1$ are identified while $b_0,b_1,b_2$ are not?

In the supply demand model $Q_s=a_0+a_1P+u$ and $Q_d=b_0+b_1P+b_2Y+v$ and $Q_s=Q_d$, where $P$ is price, $Y$ is income, $u,v$ are the unobserved error terms. what are the identified parameters and ...

I'm reading through Asymptotic Theory for Econometricians by Halbert White and am trying to figure out the intuition for situations where the errors would be correlated. Here's the setup: $Y_{t1} = Y_{... 3 votes 1 answer 64 views ### How to estimate$\gamma$in the following model? Suppose I have the following model:$Q=1(x'\beta+e>0)$,$D=1(x'\alpha+\gamma Q+u>0)$and I want to estimate$\gamma$, the error terms$e,u$are jointly normal. If$e$and$u$are correlated, can ... • 325 1 vote 1 answer 70 views ### Is it possible to get a demand function as function of income and utility from this log linear indirect utility? I have this indirect utility function: $$v=-c\frac{p^{(-β+1)}}{(-\beta+1)}+\frac{y^{(-\gamma+1)}}{(-\gamma+1)}$$ with constraint Y = c + pq I have posted before about getting the utility function from ... 1 vote 0 answers 45 views ### Multicollinearity problem I am trying to model contract outcomes, let's say for car sales and I am interested if a certain group of people is better in negotiating better deals (e.g. women).

I would like to know if the logic in these two situations is correct. Situation 1: Let's say we have a continuous dependent variable, $y_1$, that then has a causal impact on an unobserved variable, \$\...
