摘要翻译：
近年来，许多人试图将美国实际产出(GDE)增长的支出方估计数与收入方估计数结合起来，以改善实际GDP增长的估计数。我们展示了如何从多个噪声数据发布中合并信息，以提供更精确的估计，同时避免了早期工作中所需的一些识别假设。这依赖于一个新的洞察力：使用多个数据发布允许我们区分新闻和噪音测量误差，而单一年份没有。我们的新衡量标准GDP++比Aruoba等人的GDP增长衡量标准GDP+更符合数据。（2016）由费城联邦储备银行出版。历史分解表明GDE发布的信息比GDI更丰富，而在大衰退之前的季度中，使用多个数据发布尤其重要。

英文摘要：
Recent years have seen many attempts to combine expenditure-side estimates of U.S. real output (GDE) growth with income-side estimates (GDI) to improve estimates of real GDP growth. We show how to incorporate information from multiple releases of noisy data to provide more precise estimates while avoiding some of the identifying assumptions required in earlier work. This relies on a new insight: using multiple data releases allows us to distinguish news and noise measurement errors in situations where a single vintage does not. Our new measure, GDP++, fits the data better than GDP+, the GDP growth measure of Aruoba et al. (2016) published by the Federal Reserve Bank of Philadephia. Historical decompositions show that GDE releases are more informative than GDI, while the use of multiple data releases is particularly important in the quarters leading up to the Great Recession.
