The statement " An economist would look for data on past changes in the money supply, and note the resulting changes in the price level " is correct.
Explanation:
In the past, the knowledge economist will research price-money ties and observe trends; then analyse data, and establish the theory.
Financial experts analyse the market activity of economists. Their main responsibility includes the compilation and review of economic and socio-economic data, guidance on economic choices for companies and governments and the creation of models for economic predictions.
- Financial political and socio-economic data collection and review.
- Surveys and diverse sampling techniques are carried out.
- Researching different areas such as governance, economics, employment, electricity, etc.
- Using historical information. Market trends analysis.
Answer:
Confront theories predictions with evidence
Explanation:
To test economic theories, economists would observe real behavior and test it with data from the real world. Which would in turn provide evidence based on what is being tested. Confronting theories predictions with evidence is a pointer to the fact that economic theories are verifiable and their validity can be tested.

Answer:
Explanation:
Given the following data about Dayna's Doorstep Inc(DD) :
Cost given by; C = 100 - 5Q + Q^2
Demand ; P = 55 - 2Q
A.) Set price to maximize output;
Marginal revenue (MR) = marginal cost (MC)
MR = taking first derivative of total revenue with respect to Q; (55 - 2Q^2)
MC = taking first derivative of total cost with respect to Q; (-5Q + Q^2)
MR = 55 - 4Q ; MC = 2Q - 5
55 - 4Q = 2Q - 5
60 = 6Q ; Q = 10
From
P = 55 - 2Q ;
P = 55 - 2(10) = $35
Output
35(10) - [100-5(10)+10^2]
350 - 150 = $200
Consumer surplus:
0.5Q(55-35)
0.5(10)(20) = $100
B.) Here,
Marginal cost = Price
2Q - 5 = 55 - 2Q
4Q = 60 ; Q = 15
P= 55 - 2(15) = $25
Totally revenue - total cost:
(25)(15) - [100-(5)(15)+15^2] = $125
Consumer surplus(CS) :
0.5Q(55-25) = 0.5(15)(30) = $225
C.) Dead Weight loss between Q=10 and Q=15, which is the area below the demand curve and above the marginal cost curve
=0.5×(35-15) ×(15-10)
=0.5×20×5 = $50
D.) If P=$27
27 = 55 - 2Q
2Q = 55 - 27
Q = 14
CS = 0.5×14×(55 - 27) = $196
DWL = 0.5(1)(4) = $2
