Answer: b. The instrument is correlated with x1.
d. The instrument does not directly influence y, except through x1.
Explanation:
Based on the information given in the question, the necessary characteristics of a suitable instrument include:
• The instrument is correlated with x1.
• The instrument does not directly influence y, except through x1.
Some of the criteria for an instrument variable are the fact that it should have a causal effect on independent variable and also the dependent variable isn't directly affected except through the independent variable which is x1 in this scenario.
Therefore, the correct option are B and D.
The cycle time of this process for the firm is 2.89.
<h3>What is a Cycle Time?</h3>
This refers to the average time between the start of production of one unit and the start of production of the next unit of production
Cycle Time = Net time available to work / Customer demand
Cycle Time = 1.1 + 1.5 / 0.9
Cycle Time = 2.88888888889
Cycle Time = 2.89.
Therefore, the cycle time of this process for the firm is 2.89.

Answer:
C. A capital expenditure.
Explanation:
This is an example of a capital expenditure as it makes significant improvements to the machines and extends the life considerably.
These types of expenses are capitalized in the balance sheets under the original asset name and the asset is revalued by the improvement cost and stated at net book value + improvement.
Revised depreciation is then calculated on this new NBV as applicable with increased life of asset.
Hope that helps.
Answer: Option (D) is correct.
Explanation:
The economic efficiency is achieved at a point where demand curve and supply curve intersects each other. This point is known as market equilibrium. The area under the demand curve and above the equilibrium price level is known as consumer surplus.
The area above the supply curve and under the equilibrium price level is known as producer surplus.
Hence, the combine area of consumer surplus and producer surplus have to maximized to have a economic efficiency in an economy.
