The government can employ a tax policy to address concerns about negative externalities in the dairy industry. By levying a tax on producers, the private cost increases, making it a consideration for buyers and sellers. This internalizes the negative externality, leading to a social optimal output. While there are pros (tax revenue) and cons (government failure, deadweight loss), other public policy initiatives include regulating production, setting quotas, or implementing rules regarding productivity and breeding. Private individuals can also address concerns by improving product quality, reducing wastage, and promoting ethical animal treatment. However, private solutions may not be effective due to the self-centered nature of economic players.
