(a) Explain how asymmetric information between buyers and sellers can lead to market failure in the market for second-hand cars.

(b) Discuss the view that market-based responses are more effective than government regulation in addressing adverse selection, using real-world examples.

Health insurance markets often face issues related to asymmetric information, which can lead to market failures such as adverse selection and moral hazard. The government of Country X has implemented policies to address these issues by subsidizing insurance premiums and mandating universal coverage.

The government subsidizes 30% of the insurance premium for high-risk individuals. The annual insurance premium is $500 per person, and 1,000 high-risk individuals enroll in the program. Additionally, the government collects tax revenue from the general population to fund healthcare expenditures.

In 2023, the GDP of Country X was $1.5 trillion, with a population of 50 million people. The government’s total healthcare expenditure was $120 billion, of which 40% was financed through tax revenue. The country’s unemployment rate was 6%, and the Gini coefficient, which measures income inequality, was 0.38.

In response to trade liberalization policies, Country X signed a free trade agreement (FTA) with Country Y. This agreement reduced tariffs on pharmaceutical imports from 10% to 5%, leading to an increase in imported medicines by 20%. The price elasticity of demand (PED) for these medicines is estimated to be -0.8.
