3. According to Baumol and Tobin, the transactions demand for money depends upon the interest rate as well as nominal income. Explain why the transactions demand for money depends upon the interest rate. Why is this important?

4. (a) Show that a decrease in taxes causes the IS curve to shift out using a
45 degree line diagram and an IS curve diagram. (b) Show graphically and explain
intuitively how the slope of the IS curve changes when the responsiveness of
investment to the interest rate (I_{i}) increases. A detailed
mathematical answer can be substituted for the graphical analysis.
