The effect of Monetary Policy on Asset Price Inflation My macroeconomics professor told the following:
A decrease in interest rate causes that consumers rather spend their money on investments (stocks, houses) than put the money on the bank, and the increase in demand for stocks and houses causes asset price inflation in return.

However, if I try to search for a scholarly source saying the same thing, I cannot find anything. Is the above reasoning a solid one?

Thank you very much in advance!
My understanding of the effect of easing monetary policy on asset prices is that it can work through a more direct channel. 

If markets are efficient and risk neutral then generally the value of an asset $i$ is equal to the net present value of the expected cash flows generated by that project:
$$ P_i = NPV(i) = \sum_{\tau=0}^{\infty} \frac{E[C_\tau]}{\Pi_{\ell=0}^{\tau}(1+r_{\ell})} $$
Monetary policy directly lowers the denominator of the the fraction in the sum, so it raises the value of the sum. In English, by reducing the rate at which we discount future investment the present value of the asset's cash flows become more valuable. If monetary policy can also improve the economy more generally, it can also increase the expected size of the cash flows, further increasing the value of the asset (it also raises the numerator).
