在各种情况下，研究了在实施之前宣布气候政策的意外后果。我们表明，类似于所谓的“绿色-Parkway”的现象也举行时，政策的实施日期是不确定的。各国政府迫于国际和国内的压力，不得不表明减少温室气体排放的意愿。采取实际措施，比如对化石能源征收碳税，则完全是另一回事，取决于一系列政治考虑。因此，经济行为主体往往认为政策执行日期不确定。我们表明，在政策宣布和实际执行之间的过渡期，温室气体的排放量维斯于“一切照旧”的情况有所增加。
Unintended consequences of announcing a climate policy well in advance of its implementation have been studied in a variety of situations. We show that a phenomenon akin to the so-called “Green- Paradox” holds also when the policy implementation date is uncertain. Governments are compelled, by international and domestic pressure, to demonstrate an intention to reduce greenhouse gas emissions. Taking actual steps, such as imposing a carbon tax on fossil energy, is a different matter altogether and depends on a host of political considerations. As a result, economic agents often consider the policy implementation date to be uncertain. We show that in the interim period between the policy announcement and its actual implementation the emission of green-house gases increases vis-`a-vis business-as-usual.
