Answer:
The correct answer is: It allows economists to isolate or focus attention on selected variables.
Explanation:
The word ceteris paribus means other things being constant. The working of an economy is very complex, each variable is affected by a number of variables. It is difficult to understand all the complex relationships at the same time.
The assumption of ceteris paribus or other factors being constant helps the economists in isolating the variables that they want to study while keeping others constant.
It simplifies the study of economic models and helps to easily grasp the working of the economy.
Answer: 1. Large
2. Abnormal
3. True
Explanation:
1. At any level, a market’s informational efficiency is likely to be stronger when there is a <u>Large</u> number of market participants.
When there is a larger number of participants, this means that there is a large number of people able to acquire and analyse information about securities and the financial markets.
As a result of this, information is more wide ranging and easily available such that they market has very good information efficiency.
2. The potential for a security to generate <u>Abnormal</u> returns is what generates a profitable investment.
When a security is potentially able to generate abnormal returns, there is a chance of making very profitable returns if those returns are higher or lower than estimated. When returns are estimated, these are usually reflected in the market price already because they are expected, when the returns are better or worse than expected though, this means that the prices were wrong therefore giving a chance of a positive gain on the security.
3. True.
Information efficiency is very important in the market. It can mean the difference between the market being manipulated and used for unfair gains and the market being used fairly by all. Information efficiency gives every market player the same Opportunity to find out about a security and act accordingly instead of select people taking advantage of hidden Opportunities.
Answer:
3.69
Explanation:

Answer:
annual withdrawals is $1,393.87
Explanation:
given data
Amount Deposited = $5,000
Annual Interest Rate = 7.2%
First withdrawal = 2020
last withdrawal = 2025
solution
we consider equal sized annual withdrawals = x
so we can say that Amount Deposited amount will be as
$5,000 = 
..........1
we take common here 
so
$5,000 = 
solve it we get
x = $1,393.87
so that annual withdrawals is $1,393.87
