Integrating Kantian ethics affects economics in three important ways. This integration allows for a more complete understanding of human choice, incorporating not just preferences and constraints, but also principles and strength of will or character. It demonstrates the broader impact of welfare economics, which generates policies that affect not only persons' well-being, but also their dignity and autonomy. Finally, it reconciles the traditional, individualist stance in economic models of choice with the social responsibility emphasized by many systems of philosophical ethics and heterodox schools of economics.
