Abstract

We applied a method of estimating multiple effect sizes to agricultural efficiency data in Ghana. We used multi-efficiency data from 195 publications and 345 observations and fitted it to ordinary least squares regression to illustrate how the model works. The data is unique in the meta-regression efficiency space, containing all efficiency measures. We depart from existing frontier efficiency meta-regression by estimating the combined effect sizes of technical efficiency and other dimensions of frontier efficiency. We extended the single effect size estimation model to a multiple effect size estimation model. The application of the data showed that the strongest differences related to profit efficiency, the meta-regression of which has never been published. The average of the arithmetic means should not be considered as the overall efficiency, rather, the combined effect size in frontier efficiency meta-regression models.

多重效应量估计在加纳农业前沿效率元回归中的应用

我们对加纳的农业效率数据应用了一种估计多重效应大小的方法。我们使用了来自195篇出版物和345次观测的多效率数据，并将其拟合到普通最小二乘回归中，以说明模型是如何工作的。数据是唯一的元回归效率空间，包含所有的效率措施。我们从现有的前沿效率元回归出发，估计了技术效率和其他前沿效率维度的综合效应大小。我们将单效应量估计模型扩展到多效应量估计模型。数据的应用表明，最大的差异与利润效率有关，其元回归从未发表过。在前沿效率元回归模型中，算术均值的平均值不应被视为整体效率，而应被视为综合效应大小。

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.
