The level and uncertainty of inflation: results from OECD forecasts
研究通胀水平与不确定性之间的关系，使用OECD通胀预测的平方预测误差衡量不确定性，发现多数国家两者之间并无显著正相关。
There is considerable evidence that inflation variability and the level of inflation are positively related across countries. Evidence of a within-country relation is mixed. Evidence for a significant positive relation comes mostly from studies using some survey measure; contrary evidence comes mostly from studies using regression errors. Our measure of uncertainty is the squared forecast-error from Organization for Economic Cooperation and Development inflation forecasts. Most countries do not exhibit a positive and significant relation. The greatest number of positive coefficients is for relative uncertainty regressed on contemporaneous inflation.
