本文件探讨了对跨国生产率比较至关重要的若干问题。我们开发了一种“双重”方法来比较各国的全要素生产率（TFP）水平，该方法依赖于要素价格数据，而不是标准“原始”估计所需的库存数据。与基于原始估计的发展会计文献一致，我们发现TFP占各国工人人均收入差异的很大一部分。然而，我们也发现，有显着差异的TFP序列使用两种方法计算。我们将这种分歧的原因追溯到资本使用者成本和资本实物存量数据之间的不一致。此外，我们建立了标准的柯布-道格拉斯方法，假设所有国家的资本份额为三分之一，这是一个非常好的近似，更一般的公式下，各国有不同的总生产函数，不需要一个恒定的弹性替代要素。
This paper tackles a number of issues that are central to cross-country comparisons of productivity. We develop a "dual" method to compare levels of total factor productivity (TFP) across nations that relies on factor price data rather than the data on stocks offactors required by standard "primal" estimates. Consistent with the development accounting literature based on primal estimates, we find that TFP accounts for much of the differences in income per worker across countries. However, we also find that there are significant differences between TFP series calculated using the two approaches. We trace the reason for this divergence to inconsistencies between the data on user costs of capital and physical stocks of capital. In addition, we establish that the standard Cobb-Douglas methodology of assuming a constant capital share of one-third for all countries is a very good approximation to a more general formulation under which countries have different aggregate production functions that do not require a constant elasticity of substitution among factors.
