We analyze hospital efficiency and productivity growth using an innovative approach which employs the directional distance function and the Luenberger productivity indicator. The primary advantage of our approach is that both input contractions and output expansions are considered. Our model generates a productivity indicator that is decomposed into the usual constituents of productivity growth...

In this article, we introduce two community-contributed data envelopment analysis commands for measuring technical efficiency and productivity change in Stata. Over the last decades, an important theoretical progression of analysis, a nonparametric method widely used to assess performance decision-making units, is incorporation undesirable outputs. Models able deal with outputs have been develo...

Under the background of transformation main social contradictions and new stage improving quality efficiency economy, it is great significance for regional high-quality development to promote inclusive green growth city clusters along middle reaches Yangtze River. Based on SBM-Malmquist-Luenberger model, this paper measures real performance River, corresponding policy optimization suggestions a...

a r t i c l e i n f o Keywords: Malmquist–Luenberger index Urban water utilities Greenhouse gas emissions Nonparametric productivity measurement The energy use and greenhouse gas emissions in the provision of urban water and sewerage services have become an increasingly important issue in recent times. However, the impact of negative externalities such as greenhouse gas emissions on the product...

In this paper we extend the work of Färe and Zelenyuk (2003) to find a theoretically justified method of aggregating Malmquist Productivity Indexes over individual decision making units (firms, countries, etc.) into a group Malmquist Productivity Index. We also consider the aggregation of decomposed parts of the Malmquist Productivity Index to obtain a decomposition of the Malmquist Productivit...

The purpose of this paper is twofold. First, in the framework of the strategic groups’ literature, it analyses changes in productivity and efficiency of Spanish private and savings banks over an eight-year period (1998–2006). Second, by adapting the decomposition of the Malmquist productivity indices suggested by Färe et al. (1994), it proposes similar components decomposing the Luenberger prod...

Enhancing the economic and environmental efficiency of municipal solid waste (MSW) management is crucial for transitioning to a circular economy achieving cost-efficient sustainable practices. In this study, we introduce an innovative approach examine influence MSW recycling on performance over multiple years. We employ non-parametric method assess compare Malmquist Productivity Index (MPI) Mal...

The Yellow River Basin is an important energy base of China, and its green development crucial to Chinese economic transformation. In this paper, we calculate the total factor productivity (GTFP) measure level by using Slack Based Model- Global Malmquist-Luenberger (SBM-GML) index model. On basis, use a Generalized Method Moments (GMM) model further analyze impact resource endowment industrial ...

The data envelopment analysis (DEA) technique is well known for computing the Malmquist-Luenberger productivity index (MLPI) in measuring change decision-making units (DMUs) over two consecutive periods. In this research, we detect infeasibility of directional distance function (DDF) based DEA model MLPI under variable returns to scale technology when takes on negative values. We address proble...
