I have an upcoming FAQs post (it will be post 5 in two weeks…currently I am running a week ahead on the posts and post 4 is almost done and will be on monetary policy implementation…post 6 will be on treasury-central bank coordination, post 7 will start the private-bank posts) on monetary policy and the QE -asset price channel will be explained. But here is a short answer:
No bank’s don’t use cash to buy assets. If they deal with non-bank agents they just credit bank accounts, if banks deal with a fed account holder they debit their reserve balances to make payments.
The link works through interest rate, arbitrage, search for yield, and the fact that QE reduces the quantity of securities available in the market.
Reading models can be classified by whether they emphasize on lexical processes (Reader, EMMA, E-Z Reader, SWIFT) or oculomotor control processes (Competition-Interaction Theory, SERIF). Models in the first group focus on the effect of relatively high-level cognitive processes like those on word frequency, word parsing or word predictability, while models in the second group focus on the more primitive mechanisms of oculomotor processes in reading such as how word length of currently fixated word and its neighbour words affect saccade amplitude and latency (or fixation duration).
