经济如何应对有关未来政策或未来基本面的消息?标准的做法是假设代理人对这类新闻有共同的了解,并且对其他人将如何反应没有不确定性。放松这一假设会削弱新闻的一般均衡效应,并在总体水平上使某种形式的短视合理化。我们建立这些见解一类游戏嵌套,但不限于新凯恩斯主义模型。我们的研究结果有助于解决前瞻性指引难题,为财政刺激的前期加载提供了理论基础,并更广泛地说明了依赖于长期前瞻性反馈循环的预测的脆弱性。(JEL D82、D83、D84、E12、E23、E52、E62)
How does the economy respond to news about future policies or future fundamentals? Standard practice assumes that agents have common knowledge of such news and face no uncertainty about how others will respond. Relaxing this assumption attenuates the general equilibrium effects of news and rationalizes a form of myopia at the aggregate level. We establish these insights within a class of games which nests, but is not limited to, the New Keynesian model. Our results help resolve the forward-guidance puzzle, offer a rationale for the front-loading of fiscal stimuli, and illustrate more broadly the fragility of predictions that rest on long series of forward-looking feedback loops.
