I have to draw some Supply/demand curves and I want to know if they are right

Personal computers: more user-friendly software become available and the costs of inputs are reduced.
Supply moves to the right, demand moves to the left, quantity goes up and so does price

Hospital services: higher wages paid to hospital employees accompanied by 4% increases in output per labor hour.
Supply moves to the right, demand does not move, quantity goes up and price goes down

Lift tickets for skiing: increased interest in skiing; higher costs for energy used by snow making machines (in a year with little snow temps in 20's F).
Supply does not move, demand moves to the right, quantity goes up and price goes up.

one-family housing: rise in interest rates for builders and for prospective owners.
Supply moves to the left, demand moves to the left, quantity goes down and price cannot be determined

eggs: trends towards lighter breakfasts and lower cholesterol diets; higher cost of chicken feed
Supply moves to the left, demand moves to the left, quantity goes down and price cannot be determined

management information system experts: increased global activity by firms
Supply does not move, demand moves to the right, quantity goes up and price goes up

a) user-friendly software would INCREASE the demand for computers. You are correct about supply. So, Q goes up, price change uncertain.

b) higher energy costs should DECREASE supply (shift inward), Increased interest in skiing increases demand, So, Price goes up, change in Q uncertain.

c) housing: I agree

d) eggs: I agree

e) management: I agree

To determine whether the supply/demand curve for each specific case is drawn correctly, we need to consider the factors that affect supply and demand and how they are represented on the curves.

1. Personal computers:
- Factors: More user-friendly software becomes available (increasing demand) and costs of inputs are reduced (decreasing supply).
- Correct: Supply moves to the right (shifts outward), demand moves to the left (shifts inward), quantity increases, and price increases.

2. Hospital services:
- Factors: Higher wages paid to hospital employees (increasing costs of production) and 4% increases in output per labor hour (increasing supply efficiency).
- Correct: Supply moves to the right (shifts outward), demand does not move, quantity increases, and price decreases.

3. Lift tickets for skiing:
- Factors: Increased interest in skiing (increasing demand) and higher costs for energy used by snow-making machines (increasing production costs).
- Correct: Supply does not move (remains the same), demand moves to the right (shifts outward), quantity increases, and price increases.

4. One-family housing:
- Factors: Rise in interest rates for builders and prospective owners (increasing costs of borrowing).
- Not determinable: With both supply and demand shifting to the left (inward), the effect on quantity and price cannot be determined without further information.

5. Eggs:
- Factors: Trends towards lighter breakfasts and lower cholesterol diets (decreasing demand) and higher cost of chicken feed (increasing production costs).
- Not determinable: With both supply and demand shifting to the left (inward), the effect on quantity and price cannot be determined without further information.

6. Management information system experts:
- Factors: Increased global activity by firms (increasing demand).
- Correct: Supply does not move, demand moves to the right (shifts outward), quantity increases, and price increases.

Based on this analysis, some of the supply/demand curve descriptions are correct, while others cannot be determined without additional information.
