One reason is that liberal neo-classical economists like Stiglitz and Krugman share values with heterodox economists, and shared values are easily conflated with shared analysis. Another reason is that heterodox and MIT School economists also often agree on policy, even if their reasoning is different.
这种现实很难表达。原因之一是斯蒂格利茨和克鲁格曼这样的自由新古典主义经济学家与非正统经济学家的价值观有某些相似之处，而价值观的近似又很容易与分析的近似相互混淆。还有一个原因是即便推理过程有所差异，非正统和麻省理工学派经济学家却常能就政策达成一致。最后，大多数人并不相信经济学家会大胆到要在经济学领域推行统一的观点。
