The role of the state in evolutionary economics
从演化视角出发，探讨公共政策超越新古典经济学中市场失灵纠正的广泛作用，同时指出政府引导经济系统演化的能力高度有限，并尝试提出演化视角下的公共政策规范准则。
From an evolutionary perspective, the role of public policy extends far beyond the mere correction of market failures emphasised by neoclassical economics. Public policy may facilitate the market process. It may also guide the market process (in the case of multiple equilibria). The state can finally play a more creative role by allowing private agents to satisfy individually or collectively certain goals unattainable through market forces alone. However, this paper shows that although the scope of useful public policies is broader in an evolutionary approach than in neoclassical economics, the government's ability to direct the evolution of the economic system is highly limited. This paper also tries to formulate certain normative criteria which could act as public policy guidelines in an evolutionary perspective. Copyright 2004, Oxford University Press.
