Consider an infectious disease such as the flu which is spread primarily through virus particles in aerosolized respiratory droplets of already infected people. a In the midst of an infectious disease epidemic of this sort, is it privately rational for people to limit their exposure to other people, perhaps by staying home from work or not going to school? b An infected person who goes out into public areas and does not take precautions to contain their respiratory emissions clearly poses a negative externality on those around them. Does an uninfected person going out into public areas also pose a negative externality? c For a particularly severe disease outbreak of this sort, one possible government response is to exaggerate to the public both the harm that might arise from contracting the disease and the likelihood of contracting the disease. In what ways might such a strategy reduce the harm to the public from the disease epidemic? In what ways might such a strategy increase the…

As of May, 2021; 40% of the COVID-19 vaccines administered globally have gone to people in 27 wealth nations that represent only 11% of the global population. Amidst this vaccine inequality in the backdrop of the pandemic in the world, every country should have the right to make its own vaccine. That's the principle, underpinning the campaign to temporarily waive Intellectual Property (IP) protection on coronavirus vaccines. (a) Suppose the IP is waived (the know-how is available to everyone) and Bangladesh can make its own vaccine. Using the theories of demand-supply and market, discuss the impact of this scenario on the price, quantity, profit margins of the vaccine producing firms, consumers' surplus, producers' surplus in the COVID-19 vaccine market of Bangladesh. (b) Suppose the Government of Bangladesh imposes a per-unit tax on the vaccines sold by "B". Who will bear most of this tax burden and why? (c) If the IP is not waived and only one company "B" is approved for producing…
