Replication package for "The Flexible Reverse Approach for Decomposing Economic Inefficiency: With an Application to Taiwanese Banks"

This package contains the files required for replicating the results reported in the paper “The Flexible Reverse Approach for Decomposing Economic Inefficiency: With an Application to Taiwanese Banks” coauthored with Jesús T Pastor, Juan Aparicio, and Javier Alcaraz and accepted for publication in June 2024 in Economic Modelling.

The package contains:

- A Word™ file describing the content of the accompanying Excel file, where the results of the example reported in Table 1 are replicated. The file includes basic instructions for running Excel’s Solver and the Visual Basic for Applications (VBA) macros that automate the optimization processes for all firms.

- An Excel™ file consisting of four tabs. The first tab presents the data, while each successive tab includes the models and results for the weighted additive technical inefficiency (Model_1), profit inefficiency (Model_4), and the closest benchmarks maximizing profit (Model_5).

The replication files correspond to the example used to illustrate the flexible reverse approach for measuring and decomposing profit inefficiency. The data on Taiwanese banks, collected and studied by Juo et al. (2015), were kindly provided by Prof. Tsu-Tan Fu. Since these data are not publicly available, readers interested in replicating the empirical application should contact the above authors. The spreadsheets can be easily modified to measure and decompose the profit inefficiency of any dataset of choice.

本数据包包含复现论文《The Flexible Reverse Approach for Decomposing Economic Inefficiency: With an Application to Taiwanese Banks》所需的全部文件。该论文由Jesús T. Pastor、Juan Aparicio与Javier Alcaraz合著，于2024年6月被《Economic Modelling》期刊录用待刊。

本数据包包含以下内容：
- 一份Word™文档，用于说明配套Excel文件的具体内容，该文件复现了论文表1中示例的计算结果。文档包含运行Excel求解器（Excel Solver）以及用于自动化全企业优化流程的Visual Basic for Applications（VBA）宏的基础操作指南。
- 一份包含四个工作表的Excel™文件：首个工作表用于展示原始数据集，后续三个工作表分别收录加权加法技术无效率模型（Model_1）、利润无效率模型（Model_4）以及最大化利润的最邻近基准模型（Model_5）的模型设定与计算结果。

本复现文件对应用于阐释灵活逆向法测度与分解利润无效率的示例数据集。该台湾银行数据集由Juo等人（2015）收集并开展研究，由傅祖坛（Tsu-Tan Fu）教授慷慨提供。由于该数据集未对外公开，有意复现该实证应用的读者请联系上述论文作者。本数据包内的电子表格可便捷修改，以测度与分解任意自选数据集的利润无效率。
