In economics, the Fisher equation is used to determine the
relationship of the nominal interest rate and the real interest rate. This
equation takes into account the effect of inflation. Mathematically this is
expressed as:
Real rate = 
-1
The values given are:
Nominal rate= 10% =
0.1
Inflation=5%=0.05
Substituting known
values and by calculation:
<span>Real rate=0.0476 =
4.76%</span>
Answer:
<em>c. The reasoning of both Alfons and Mary suffers from the omitted variable problem</em>
Explanation:
The issue of omitted variables occurs as a result of mis-specification of a linear regression model, which could be either because the impact of the omitted variable on both the dependent variable is unclear, or the evidence was not accessible.
This causes you to omit the variable from your regression, resulting in over-estimation (upward bias) or underestimation (downward) of the influence of one of the other predictor variables.
Four major categories of Primary energy use are:
1. Transportation
2. Industrial Process
3. Commercial and residential use
4. Generation of electrical power
Transportation depends entirely on petroleum, whereas
nuclear power, coal, and water power are limited to the production of
electricity. Electricity is in most commercial and residential use. Industrial processes
use natural gas, oil, and electricity. Some oil, natural gas and biomass are
used for the generation of electricity.
When the demand for bikes has considerably increased with a rise in price by $10, then the profit also increases by $10 on every bike sold.
<h3>What is meant by profit?</h3>
Profit is an incentive earned by a company by selling its products at a price higher than the original cost.
From the provided situation, it has been analyzed that there is a direct relationship between price and demand, which means an increase in demand leads to a rise in prices also. This will ultimately raise the profits of a company in respect of goods sold.
Therefore, the profits are also raised by $10 in a similar way as the rise in price by $10 due to an increase in demand for bikes.
