Summary
Government policies aim to achieve efficient resource allocation and correct market failures through various tools such as taxes, subsidies, regulations, and more. These interventions address both negative and positive externalities to improve economic outcomes.
- Specific and Ad Valorem Indirect Taxes — Taxes imposed on goods to internalize external costs. Example: Pigouvian tax on firms causing pollution.
- Subsidies — Financial support to encourage production or consumption of beneficial goods. Example: Subsidies for vaccines to increase public health.
- Regulations — Rules set by authorities to control activities causing externalities. Example: Emission limits for vehicles to reduce air pollution.
- Pollution Permits — Tradable permits allowing a certain level of pollution. Example: Emission Trading Scheme in China.
- Property Rights — Legal rights to use resources, helping to manage externalities. Example: Assigning rights to reduce pollution through negotiation.
- Provision of Information — Disseminating knowledge to influence consumer and producer behavior. Example: Health warnings on tobacco products.
- Behavioural Insights and 'Nudge' Theory — Techniques to subtly guide better decision-making. Example: Campaigns to promote vaccination uptake.
