But an excessive focus on vested interests can easily divert us from the critical contribution that policy analysis and political entrepreneurship can make. The possibilities of economic change are limited not just by the realities of political power, but also by the poverty of our ideas.
政治经济学毫无疑问是重要的。如果不能对现状带给我们的潜在得失做明确的理解，就很难明白现行政策。但过度关注既得利益很容易让我们注意力分散，不再关注政策分析和政治创业家所作出的关键性贡献。经济变迁的可能性不仅受政治权力制约，也受我们缺少好主意的制约。
