Consider a supply and demand model written in its most general implicit form, using capital Greek letters
Question:
Consider a supply and demand model written in its most general implicit form, using capital Greek letters for the unknown parameters and \(E_{i}\) for the random errors,
a. Multiply each equation by 3 . Do they remain true?
b. Multiply the demand equation by \(-1 / \Gamma_{11}\). Does it remain true?
c. Define \(\alpha_{21}=-\Gamma_{21} / \Gamma_{11}, \beta_{11}=-\mathrm{B}_{11} / \Gamma_{11}, \beta_{21}=-\mathrm{B}_{21} / \Gamma_{11}, e_{1}=-E_{1} / \Gamma_{11}\) and write the demand equation with \(q\) on the left-hand side and the remaining terms on the right-hand side. By choosing \(q\) to be on the left-hand side of the equation, we have chosen a normalization rule.
d. Repeat the process for the supply equation, beginning by multiplying through by \(-1 / \Gamma_{22}\), and obtain the normalized supply curve with
Write the normalized supply equation with \(p\) on the left-hand side and the remaining terms on the right side.
e. Mathematically, in a system of jointly determined variables, it does not matter which variable appears on the left side of each normalized equation. True or false?
