Abstract: | Since development is a process rather than an end-state, all countries are always in a constant state of change, regardless of their level of income. This article focuses on the challenges that affluent countries face today in shifting to a sustainable development path. These challenges include improving the quality of life, achieving environmental sustainability, and addressing inequality. In the United States in particular, these challenges have increased in recent decades, despite significant economic growth. The neoclassical development model assumes that growth makes it easier to achieve sustainable development and that wellbeing rises with per capita income. We question these assumptions, and find a theory of economic development in institutional economics that better explains and accommodates sustainability. We draw on the work of many original institutionalist economists (OIE), and others working in this tradition, to analyze the challenges of sustainable development in affluent countries, especially in the United States. |
