a) To determine if either hospital has a dominant strategy, we need to compare the payoffs for each hospital's services.
For Hospital B:
- If Hospital A offers basic care, the payoffs are 5 and 7 for basic, 9 and 8 for all-purpose, and 6 and 10 for specialty.
- If Hospital A offers all-purpose care, the payoffs are 5 and 4 for basic, 4 and 7 for all-purpose, and 6 and 12 for specialty.
- If Hospital A offers specialty care, the payoffs are 13 and 6 for basic, 7 and 4 for all-purpose, and 3 and 3 for specialty.
From these payoffs, we can see that for each service choice by Hospital A, the payoffs for Hospital B vary. Therefore, there is no dominant strategy for Hospital B.
Similarly, for Hospital A:
- If Hospital B offers basic care, the payoffs are 5 and 7 for basic, 5 and 4 for all-purpose, and 13 and 6 for specialty.
- If Hospital B offers all-purpose care, the payoffs are 9 and 8 for basic, 4 and 7 for all-purpose, and 7 and 4 for specialty.
- If Hospital B offers specialty care, the payoffs are 6 and 10 for basic, 6 and 12 for all-purpose, and 3 and 3 for specialty.
Again, there is no dominant strategy for Hospital A.
To find the Nash equilibrium strategies, we need to look for situations where neither hospital has an incentive to deviate from their chosen strategy. In this case, the Nash equilibrium occurs when both hospitals choose their all-purpose services. This is because if Hospital A chooses all-purpose, Hospital B's best response is also all-purpose, and vice versa.
b) If the hospitals coordinate and communicate with each other, they can jointly choose their strategies to maximize their combined profits. In this case, they should both choose the strategy that gives them the highest joint profit. Looking at the payoffs, the strategy that maximizes the joint profit is for both hospitals to offer specialty care.
c) A hospital merger may generate an increase in profit for several reasons:
- Economies of scale: Merging hospitals can lead to lower costs per patient by consolidating resources, sharing administrative costs, and optimizing the utilization of equipment and facilities.
- Enhanced bargaining power: A merged hospital may have more leverage in negotiations with insurance companies and suppliers, allowing them to secure better reimbursement rates or lower prices for medical supplies.
- Improved specialization: Merging hospitals can result in the consolidation of specialized services, leading to improved expertise, wider range of services, and attracting more patients.
- Increased market share: A merger can expand the merged hospital's market presence, allowing it to capture a larger share of patients and potentially increase revenue.
- Improved financial stability: A merger may provide financial stability by combining resources and pooling risks, making it easier to invest in advanced medical technologies and infrastructure.
It's important to note that the outcomes of hospital mergers can vary depending on the specifics of the situation and the local market conditions.
