Do taxspots matter?
研究了政府是否应通过不确定的财政政策（即税收斑点）来融资，分析了在标准拉姆齐问题中税收斑点最优且反复出现的条件，发现谨慎和市场不完全性起关键作用。
Should the government run an uncertain fiscal policy to finance its liabilities? We call the resulting uncertainty taxspots, and study conditions that make taxspots optimal and recurrent in standard Ramsey problems. We show that prudence and market incompleteness play a role in sustaining taxspots, and that equal-treatment randomizations can be decentralized via taxspots even in the absence of financial markets.
