Abstract

We analyze diverse and heterogeneous literature to grasp the general effect size of financial development on economic growth on a world scale. For that, we perform by far the largest available meta-analysis of the finance–growth nexus using 3561 estimates collected from 177 studies. Our meta-synthesis results show that large heterogeneity in empirical evidence is, in fact, driven by only a limited number of variables (moderators). By using advanced techniques, we also document the existence of the publication selection bias that is propagated in the literature in a nonlinear fashion. We account for uncertainty in moderator selection by employing model-averaging techniques. After adjusting for the publication bias, the results of our meta-regression provide evidence of a small but genuine positive effect of the financial development on growth that very mildly declines over time. Finance channeled via capital markets seems to be more beneficial for economic growth than that provided in the form of private credit. Our evidence goes against arguments about the damaging role of financial development and is in line with century-old theoretical foundations that favor the positive role of finance on economic growth.

探寻金融对经济增长的一般效应大小:对全球研究的大型荟萃分析
摘要 我们分析了各种不同的文献,以掌握金融发展对全球经济增长的总体影响程度。为此,我们利用从 177 项研究中收集的 3561 个估计值,对金融与经济增长的关系进行了迄今为止最大规模的元分析。我们的元综合结果表明,经验证据中的巨大异质性实际上仅由数量有限的变量(调节因素)驱动。通过使用先进的技术,我们还记录了文献中以非线性方式传播的发表选择偏差的存在。我们通过使用模型平均技术来考虑调节因子选择的不确定性。在对发表偏差进行调整后,我们的元回归结果证明,金融发展对经济增长的积极影响虽小,但确实存在,而且随着时间的推移,这种影响会逐渐减弱。与私人信贷相比,通过资本市场提供的金融似乎更有利于经济增长。我们的证据与有关金融发展的破坏性作用的论点背道而驰,并与支持金融对经济增长的积极作用的百年理论基础相一致。

期刊介绍: Empirical Economics publishes high quality papers using econometric or statistical methods to fill the gap between economic theory and observed data. Papers explore such topics as estimation of established relationships between economic variables, testing of hypotheses derived from economic theory, treatment effect estimation, policy evaluation, simulation, forecasting, as well as econometric methods and measurement. Empirical Economics emphasizes the replicability of empirical results. Replication studies of important results in the literature - both positive and negative results - may be published as short papers in Empirical Economics. Authors of all accepted papers and replications are required to submit all data and codes prior to publication (for more details, see: Instructions for Authors).The journal follows a single blind review procedure. In order to ensure the high quality of the journal and an efficient editorial process, a substantial number of submissions that have very poor chances of receiving positive reviews are routinely rejected without sending the papers for review.Officially cited as: Empir Econ
