Final answer:
High-income countries favor the wealthy, while middle-income and low-income countries adopt policies suitable for their income groups.
Step-by-step explanation:
The policy prescriptions of high-income, middle-income, and low-income countries differ based on their respective economic situations.
High-income countries often implement policies that favor high-income individuals, such as providing tax benefits or subsidies for investment and innovation. This is done to maintain economic growth and attract foreign investment.
On the other hand, middle-income and low-income countries adopt policies that are suitable for their income groups. For example, low-income countries focus on market-oriented policies, education, and healthcare to uplift their population from poverty traps. Middle-income countries strive for increases in physical capital and innovation to drive economic growth.
Each country needs to take into account their specific economic circumstances and the needs of their population when formulating policies.
