How will you choose to contribute to the public good over not contributing, and what factors must be considered. Solution Public goods are goods that everyone (contributors and non-contributors alike) can enjoy, once they are provided. Casual observations in economic system highlights that sometimes people choose to contribute to the public good over not contributing, even when we recognize the pull to free ride on the contributions of others. This contribution can be in the following forms: effort in work teams, provision of tangible or intangible public goods, the use of natural resources (the tragedy of the commons), contributions to charities, tax honesty, buyer-seller relationships, employer-employee relationships. The explanatory factors which motivates people to contribute may be efficient coercion, selective incentives, institutional structure, government trustworthiness, social norms, social capital, ethical reciprocity, and dispositions.
