Use supply and demand models to illustrate how the following changes would affect the demand curve or the supply curve for inpatient services at a hospital in a large city. Be sure to label old and new curves (D1=old demand, D2= new demand, S1=old supply, and S2=new supply). What is the impact on price (increase/decrease) and quantity (increase/decrease)? (a) Average real income in the community increases. (b) A number of physicians in the area join together and open up a discount-price walk-in clinic. Suppose physician services and inpatient hospital services are complements. (c) Suppose the hospital building goes through a renovation. Using supply and demand analysis, show graphically and explain in words some of the factors that may have led to rising health care prices in the United States from 1960s to the present day.

Suppose demand curve is given by P = Q + 10 and the supply curve is given by P = Q + 2. P denotes Price and Q denotes Quantity. (a) Graph both the supply and demand curves. (b) What is the equilibrium price and quantity (P and Q)? (c) Calculate consumer surplus. Shade appropriate area in graph. (d) Calculate producer surplus. Shade appropriate area in graph. (e) Calculate total surplus.

Suppose XER Inc. is a monopoly and produces a drug that cures the common cold. The weekly market demand for its product takes the form P = 4Q + 660, where Q is measured as number of tablets. The marginal costs (MC) are equal at $100 per tablet (a horizontal marginal cost curve). (a) Given this information, solve for the level of output that will be produced by XER Inc. if it maximizes profits. Remember: You can calculate Marginal Revenue curve from demand curve. (b) Solve for the price charged. (c) From a societal point of view, does the profit-maximizing level of output represent an efficient level of output? Why or why not? (d) Suppose the source of the entry barrier was removed so XER is no longer a monopoly. What will be the new equilibrium?

Introduction

Healthcare markets in the United States have historically been characterized by complex interactions of supply, demand, and government regulation, which contribute to the persistent issue of rising healthcare costs. Understanding these dynamics through supply and demand models provides valuable insights into how various events and policy changes influence prices and quantities of healthcare services. This paper explores several scenarios affecting inpatient hospital services, analyzes market equilibrium, and examines the effects of monopoly pricing on pharmaceuticals.

Impact of Changes on Inpatient Services

a) Increase in Average Real Income

When the community’s average real income rises, the demand for healthcare services, including inpatient hospital services, generally increases. Healthcare is considered a normal good; as income increases, individuals tend to consume more healthcare services. Graphically, this shift results in a rightward shift of the demand curve from D1 to D2, indicating higher demand at each price level. The new equilibrium point will feature a higher price and a higher quantity of inpatient services, reflecting increased utilization driven by greater purchasing power.

b) Introduction of Discount-Price Walk-In Clinics by Physicians

The entry of discounted walk-in clinics by physicians introduces a substitute for inpatient services, especially for less severe health issues. As these clinics become more accessible and affordable, the demand for inpatient services decreases, shifting the demand curve leftward from D1 to D2. This decrease in demand leads to a reduction in both price and quantity of inpatient services, assuming supply remains unchanged. Consumers might prefer the convenience or lower costs of walk-in clinics, which diminishes the hospital’s market share.

c) Renovation of Hospital Buildings

Renovations and improvements in hospital infrastructure and facilities typically increase the perceived quality of inpatient services. As consumers value quality healthcare more highly, their willingness to pay for inpatient services increases, resulting in a rightward shift of the demand curve from D1 to D2. The effect on prices is an increase, accompanied by a rise in the quantity of services provided, assuming supply remains stable. Additionally, renovations may temporarily reduce the hospital's supply due to construction disruptions, which can further elevate prices in the short term.

Factors Contributing to Rising Healthcare Prices

Several factors have contributed to escalating healthcare costs in the United States from the 1960s to the present:

1. Technological Advancements: Innovations such as advanced imaging and minimally invasive surgeries improve care but increase costs (Cutler & McClellan, 2001).

2. Aging Population: Growing proportions of elderly individuals with chronic conditions demand more resources, driving up costs (Hoffman et al., 2018).

3. Administrative Expenses: Complex billing and insurance processes add administrative costs to healthcare providers (Bpc, 2019).

4. Provider Market Power: Hospitals and physicians often possess market power, allowing them to set higher prices (Carroll et al., 2015).

5. Pharmaceutical Innovation: High prices for new drugs and treatments augment overall healthcare expenditure (Kesselheim et al., 2016).

6. Defensive Medicine: Physicians ordering unnecessary tests to avoid malpractice suits inflate costs (Studdert et al., 2005).

Market Graphing and Equilibrium Analysis

Given the demand curve P = Q + 10 and supply curve P = Q + 2, the equilibrium can be calculated by setting demand equal to supply:

Q + 10 = Q + 2

=> 10 = 2

which indicates an inconsistency; thus, adjusting the demand curve to P = -Q + 10 (more typical in downward sloping demand) better suits analysis. Assuming P = -Q + 10 for demonstration:

Set demand and supply equal:

- Q + 10 = Q + 2

=> -Q - Q = 2 - 10

=> -2Q = -8

=> Q = 4

Substituting into either equation:

P = -4 + 10 = 6

Therefore, equilibrium price (P) is $6, and quantity (Q) is 4 units.

Consumer and Producer Surplus

Consumer surplus corresponds to the area above the market price and below the demand curve up to Q*:

- Max willingness to pay at Q=0: P=10 (from P = -Q + 10).

- Consumer surplus = 0.5 (height) (base) = 0.5 (10 - 6) 4 = 8.

Producer surplus is the area below the price line and above the supply curve up to Q*:

- Minimum acceptable price at Q=0: P=2 (from P=Q + 2).

- Producer surplus = 0.5 (6 - 2) 4 = 8.

Total surplus = Consumer surplus + Producer surplus = 16.

Pharmaceutical Monopoly and Market Outcomes

a) Profit-Maximizing Output and Pricing for XER Inc.

The demand function: P = 4Q + 660

Marginal Cost (MC): $100 per tablet

Step 1: Derive Total Revenue (TR) and Marginal Revenue (MR):

TR = P Q = (4Q + 660) Q = 4Q^2 + 660Q

MR = d(TR)/dQ = 8Q + 660

Step 2: Set MR = MC to find optimal output:

8Q + 660 = 100

=> 8Q = -560

=> Q = -70

Since quantity cannot be negative, this indicates the demand curve as specified is invalid for profit maximization with MC = $100; likely, the demand curve was miswritten. Adjusting the demand curve to P = -Q + 660 for demonstration:

TR = (-Q + 660) * Q = -Q^2 + 660Q

MR = d(TR)/dQ = -2Q + 660

Set MR = MC:

-2Q + 660 = 100

=> -2Q = -560

=> Q = 280 units

Price:

P = -Q + 660 = -280 + 660 = $380

b) Price at Equilibrium: $380

c) Societal Efficiency of Monopoly Pricing

The monopoly produces less output and charges higher prices than the socially optimal level, which is where price equals marginal cost (P = $100). Here, the monopoly produces Q = 280 units, and price is $380, indicating significant deadweight loss and inefficiency from a societal perspective because the quantity is less than the socially efficient quantity, and consumers demand more at a lower price.

d) Removal of Entry Barriers and Market Equilibrium

Without monopoly power, competitive markets would produce at P = MC = $100, with quantity determined by demand:

Q = (660 - P)/4 = (660 - 100)/4 = 155 units

In competitive equilibrium, price drops to $100, and output increases to 155 units, maximizing societal welfare.

Conclusion

Analyzing various scenarios through supply and demand frameworks elucidates the factors influencing healthcare costs and market outcomes. Increased income and infrastructure improvements tend to raise demand and prices; competition from alternative providers can moderate demand; and monopolistic control negatively impacts social efficiency. Policymakers should consider these dynamics to foster a more equitable and efficient healthcare system.
