摘要

本文提出了一种对常用的生产率增长会计分解的修正，用于校准内生增长模型。具体而言，进一步分解企业内部成分以显示企业生产率增长率和相对水平的协方差。这一时刻提供了有关相对生产率分配的系统性波动的信息，在内生增长模型中，这种波动源于企业的投资行为，从而影响总收入增长。这种分解允许评估建模假设和量化引入或影响跨公司增长的不同激励的参数。

Revisiting productivity growth accounting decompositions

This paper proposes a modification to popular productivity growth accounting decompositions useful for calibrating endogenous growth models. Specifically, the within-firm component is further decomposed to show the covariance of firms’ productivity growth rates and relative levels. This moment provides information about the systematic churning within the relative productivity distribution that, in endogenous growth models, stems from firms’ investment behavior, thus affecting aggregate income growth. This decomposition allows assessing modeling assumptions and quantifying parameters that introduce or affect differential incentives to grow across firms.

期刊介绍： Established in 1947, Research in Economics is one of the oldest general-interest economics journals in the world and the main one among those based in Italy. The purpose of the journal is to select original theoretical and empirical articles that will have high impact on the debate in the social sciences; since 1947, it has published important research contributions on a wide range of topics. A summary of our editorial policy is this: the editors make a preliminary assessment of whether the results of a paper, if correct, are worth publishing. If so one of the associate editors reviews the paper: from the reviewer we expect to learn if the paper is understandable and coherent and - within reasonable bounds - the results are correct. We believe that long lags in publication and multiple demands for revision simply slow scientific progress. Our goal is to provide you a definitive answer within one month of submission. We give the editors one week to judge the overall contribution and if acceptable send your paper to an associate editor. We expect the associate editor to provide a more detailed evaluation within three weeks so that the editors can make a final decision before the month expires. In the (rare) case of a revision we allow four months and in the case of conditional acceptance we allow two months to submit the final version. In both cases we expect a cover letter explaining how you met the requirements. For conditional acceptance the editors will verify that the requirements were met. In the case of revision the original associate editor will do so. If the revision cannot be at least conditionally accepted it is rejected: there is no second revision.
