Arrange the following stages in the process of addressing positive externalities in consumption to promote societal wellbeing: A) Government identifies a positive externality, B) Policies are implemented to encourage consumption, C) Increased consumption leads to societal benefits, D) Evaluation of the effectiveness of policies.

To address positive externalities in consumption, the process begins when the government identifies a positive externality. This means they recognize that certain goods or services, like education or public parks, provide benefits not just to the individual using them but also to society as a whole. Next, the government implements policies to encourage more people to consume these goods, such as subsidies or tax breaks. As a result of these policies, increased consumption occurs, leading to greater societal benefits, like a more educated population or improved public health. Finally, it's important for the government to evaluate how effective these policies have been in achieving their goals, ensuring that the benefits continue to grow.
