Question
The COVID-19 vaccination program in India illustrates key economic concepts such as positive externalities, public goods, and market failure. Vaccination provides private marginal benefits (PMB), such as personal health protection, but also generates social marginal benefits (SMB) by reducing virus transmission and easing the burden on healthcare systems. The SMB is greater than the PMB because society benefits more from widespread vaccination than individuals do. Without intervention, the market would lead to under-vaccination, as individuals do not account for these external benefits, leading to a socially suboptimal outcome.
To address this market failure, government intervention through free or subsidized vaccines ensures that the positive externalities are internalized, aligning private incentives with social benefits. This helps achieve the socially optimal outcome, where the SMB equals the social marginal cost (SMC). By making vaccines widely accessible, the government corrects the under-consumption of vaccines, ensuring public health is maximized and the broader societal benefits are fully realized.
Explain this in economic terms and concept using graph and elaborate on policy implications.

- Suppose Homer and Smithers are in the same health insurance pool and they pay the same premium for their health insurance. Suppose further, that the SNPP discriminates against employees on the basis of body weight so that a negative wage penalty is associated with obesity. Finally, suppose Homer eschews exercise and loves jelly donuts much more than Smithers does. As a result, Homer also has much higher expected medical expenditures. Does Homer impose a negative externality on Smithers?

Draw a supply and demand graph for vaccines that shows a private (individual) market demand curve for vaccines (D) that obeys the law of demand and a market supply curve (S) for vaccines that obeys the law of supply. Label the equilibrium price (P) and quantity (Q) of vaccines produced in the free market.arrow_forward

By contrast, in Beveridge countries, centralized health technology assessment is required before the public health care system will cover expensive new technologies. What is the nature of the social costs associated with covering a new technology in a Beveridge public health care system? What is the nature of the social costs associated with not covering a new technology in such a system?
