Producers and producer-groups spend this social premium to support socioeconomic development in a variety of ways. One common way to spend the social premium of fair trade is to privately invest in public goods that infrastructure and the government are lacking in. These public goods include environment initiatives, public schools, and water projects. At some point, all producer-groups re-invest their social premium back into their farms and businesses. They buy capital, like trucks and machinery, and education for their members, like organic farming education. Thirty-eight percent of producer-groups spend the social premium in its entirety on themselves, but the rest invest in public goods, like paying for teachers' salaries, providing a community health care clinic, and improving infrastructure, such as bringing in electricity and bettering roads.
