摘要

本文试图衡量经济学研究的进展。为了衡量进步,我们依赖于一个客观的、标准化的衡量标准:经济学家对宏观经济指标的预测准确性。我们对经济预测准确度随时间变化的趋势进行描述性、探索性研究。数据来自专业人士对1968年以来美国失业率和名义GDP的预测。这里的分析显示,没有证据表明预测准确性有所提高。讨论了这一发现的几个潜在原因和含义。

Progress in Economics
This paper is an attempt to measure progress in economics research. In order to measure progress, we rely on an objective, standardized measure: economists’ accuracy forecasting macroeconomic indicators. We undertake a descriptive, exploratory study of trends over time in economic forecasting accuracy. Data comes from professionals’ forecasts of US unemployment and nominal GDP since 1968. The analysis here shows no evidence of improvement in forecasting accuracy. Several potential causes and implications of this finding are discussed.
