Moreover, beyond effective regulation (including ensuring a level playing field for competition), modern economies are founded on technological innovation, which in turn presupposes basic research funded by government. This is an example of a public good – things from which we all benefit, but that would be undersupplied (or not supplied at all) were we to rely on the private sector.
此外，除了有效监管（包括确保为竞争提供平等舞台），现代经济的基础是技术创新，后者反过来要求政府资助的基础研究。这是一个我们都能从中获益的公共品的例子，但如果我们只依靠私人部门，那么这一公共品将是供给不足的（或者根本不存在供给）。
