D. decreases; demand for money E None of the above 3. Suppose the money supply remains constant and the money demand curve shifts left. This is illustrated on a graph of the money market as in the demand for money and that creates A an increase: an excess demand for money that is eliminated by rising prices B an increase: an excess demand for money that is eliminated by falling prices C a decrease: an excess demand for money that...
5. Suppose you want to estimate by MCO the following function: ? = ?0?1?1?2?2? Using the proposed function, suggest a model that allows econometric estimation by MCO. What benefit does the transformation you proposed offer? Explain the assumptions that the error term must meet to obtain an estimate by MCO that can be validated as adjusted to reality. 5. Suponga que desea estimar por MCO la siguiente función: y = Box, B1xxBze Utilizando la función propuesta, sugiera un modelo que...
