However, since conditions for a perfect market do not exist in a real capital market, security prices may not fully reflect all relevant information. Fama therefore pointed out the need to define the requirement for a stock price to fully reflect information in EMH in terms of expected return from holdings a security. He also pointed to the need to define relevant information in the EMH, and in defining it, he divided the market into three levels: the weak form, the semi strong form and the strong form. The EMH has three sub-hypotheses: the weak form, semi strong and strong form efficient market hypotheses. Each deals with a different level of cumulative information.

By borrowing so much money, the government “crowds out” private individuals and private commercial interests. Now, the way these shortages get rationed, is for the prices to be pushed up, which is represented by a shift from i0 to i1 (also meaning interest rates are pushed up) Graph 2: The “Crowding Out” Effect Once interest rates are pushed up, it brings unintended and opposite effects on the AD. Consumer spendings will go down, businesses won’t be able to afford money to buy new capitals, leading to decreases in investment spendings and consumer spendings. These are parts of AD, therefore the AD is shifted partway back as shown in graph 3 below. In this case, overall unfortunately, the intended expansionary fiscal policy is diminished.
