Answer:
a) H0: u = presence of a unit root
HA: u ≠ presence of a unit root ( i.e. stationary series )
b) t stat = -0.064
c) We will reject the Null hypothesis and the next step will be to accept the alternative hypothesis
d) It is not valid to compare the estimated t stat with the corresponding critical value because a random walk is non-stationary while the difference is stationary because it is white noise
Explanation:
<u>a) stating the null and alternative hypothesis</u>
H0: u = presence of a unit root
HA: u ≠ presence of a unit root ( i.e. stationary series )
<u>b) performing the test </u>
critical value = -2.88
T stat = coefficient / std error
= -0.02 / 0.31 = -0.064
c) From the test, the value of T stat > critical value we will reject the Null hypothesis hence the next step will be to accept the alternative hypothesis
d) It is not valid to compare the estimated t stat with the corresponding critical value because a random walk is non-stationary while the difference is stationary because it is white noise
Answer:
unit of account, a store of value, and a medium of exchange.
Explanation:
Functions of money
1. Medium of exchange : money can be used to exchange for goods and services. For example, money serves as a medium of exchange when you pay $20 for your favourite jeans
2. Unit of account : money can be used to value goods and services, For example, $20 is the value of your favourite jeans
3. Store of value : money can retain its value over the long term, this it can be used as a store of value
Answer:
- Sacred consumption
- Profane consumption
Explanation:
This differentiation is based on special religious events (e.g. religious holidays) that considered some goods as sacred, while profane had to do with everyday life.
Some modern marketing strategies try to build sacred brands. For example, Google has become our God of all knowledge and no one even dares to challenge that almost religious belief. Anyone can make their own coffee or buy coffee at any coffee shop, but Starbucks is different, it has built a sense of emotional connection with the public. It's not any coffee that we need or want.
The formula for annual depreciation by means of the units-of-production method is:
(depreciable cost / estimated output) x the actual yearly output
Under the units of production method, the quantity of depreciation indicted to expense differs in direct proportion to the amount of asset usage. Therefore, a business may charge more depreciation in times when there is more asset consumption and less depreciation in times when there is a smaller amount of usage. It is the most precise method for indicting depreciation as this method relate thoroughly to the wear and tear on assets. Though, it also needs that someone should track asset usage which means that its use is commonly restricted to more luxurious assets. It needs estimation of the total usage over the life of the asset in order to come up with the amount of depreciation to identify in separate accounting period.
