The impact of the subsidy policy on total factor productivity : an empirical analysis of China's cotton production
2013
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from the publisher at: http://dx.doi.org/10.1155/2013/248537 Open access This paper develops one model to explore the relationship between the subsidy policy and the agricultural total factor productivity (TFP). It indicates that the agricultural TFP will be lower after the subsidy policy is implemented and there exists a negative relation between the subsidy and TFP, if subsidies are associated with the acreage. Using Malmquist index, this paper measures the changes of TFP in China's cotton production before and after the subsidy policy is implemented. The results verify that the subsidy po…
Health Insurance Reforms and Health Policies in Rural China
2016
Since the early 2000s, the Chinese government has undertaken a series of reforms in the health sector. Among these, the three most important have been concerned with medical insurance, hospital administration, and pharmaceutical policies. The aims of these reforms were to extend health insurance coverage, to increase the activities and the efficiency of the health establishments, and to improve patient care. This article focuses on two components of these reforms: the development of health insurance in rural areas and the policy on essential medicines in conjunction with hospital reforms. Our longstanding co-operation with a research team from Weifang University and with the Weifang Health …

The effect of the launch of bitcoin futures on the cryptocurrency market: an economic efficiency approach
2021
We analyze the economic efficiency of the cryptocurrency market after the launch of Bitcoin futures by means of the Data Envelopment Analysis and Malmquist Indexes. Our results show that the introduction of Bitcoin futures did not affect the economic efficiency of the cryptocurrency market. However, we observe that Bitcoin obtained the highest risk-return trade-off due to its liquidity compared to the rest of cryptocurrencies. Therefore, our paper underlines the support of investors on Bitcoin to the detriment of the rest of cryptocurrencies.
An intertemporal approach to measuring environmental performance with directional distance functions: Greenhouse gas emissions in the European Union
2014
Abstract The impact of economic activity on the environment is a matter of growing concern for firm managers, policymakers, researchers and society as a whole. Building on previous work by Kortelainen (2008) [Dynamic environmental performance analysis: A Malmquist index approach. Ecological Economics 64, 701–715], we contribute an approach to assessing intertemporal environmental performance at the level of the management of specific pollutants, as the result of change in eco-efficiency and environmental technical change, which identify catching-up with best available environmental practices and eco-innovation, respectively. In doing so, we use Data Envelopment Analysis techniques, directio…
Industrial productivity and convergence in Chinese regions: The effects of entering the world trade organisation
2011
Abstract Chinese economic growth is tremendously important, both due to how fast it is occurring and also its effect on the world economy as a whole. The size of the economy and the rate at which it is growing has opened up significant internal regional differences that are visible in the trends displayed by industry as the main exponent of this growth. This article analyses regional differences in industrial productivity using a dynamic approach (Malmquist index), that is, by determining regional productivity growth as well as the change in value added inequality from one region to another (sigma and beta convergence). Both approaches distinguish between the periods dating from 1995 to 200…
Convergence in OECD countries: technical change, efficiency and productivity
1998
The aim of this study is to analyze labor productivity convergence in the countries of the OECD over the period 1965-90. A non-parametric frontier approach is used to calculate the Malmquist productivity index. By breaking it down, the contribution to the growth of labor productivity of technical progress, of changes in efficiency, and of the accumulation of inputs per worker are quantified. Unlike other studies, the results obtained show that technical change has worked against labor productivity convergence, since it has always been greater in the countries with higher labor productivity. El trabajo tiene como objetivo básico analizar la contribución de las distintas fuentes del crecimien…
Productivity of wastewater treatment plants in the Valencia Region of Spain
2017
Abstract This study analyses the evolution of productivity over the 2008–2012 period for a homogenous set of 199 wastewater treatment plants that are located in the Valencia Region of Spain and utilize the same treatment technology, using the smoothed bootstrap Malmquist productivity index based on Data Envelopment Analysis (DEA). The results reveal a negative trend in productivity that is mainly the result of resource management rather than an inappropriate level of innovation or use of new technologies. In addition, the effect of exogenous factors on productivity is analysed using the Kruskal-Wallis (KW) test, finding that productivity levels were affected by the quality of the influent w…
The Luenberger productivity indicator in the water industry: An empirical analysis for England and Wales
2014
Abstract We innovate in the field of water companies' performance with an application of the directional distance function and the Luenberger productivity indicator (LPI) to the assessment of water companies' productivity growth. The advantage of our approach is that it takes into account both input contractions and output expansions. The analysis covered 22 water companies from England and Wales using data over the period 2001–2008. To the best of our knowledge, there are no prior studies applying the Luenberger productivity indicator to the water industry in England and Wales or other countries. For the sake of comparison, the traditional Malmquist productivity index (MPI) was also estima…
Efficiency and Productivity of Italian Touris Destinations: A Quantitative Estimation Based on Data Envelopment Analysis and the Malmquist Method
2007
This paper aims to provide a statistical analysis of the relative economic performance of Italian tourist areas. It uses two modelling approaches to estimate the competitiveness of these regions, viz. data envelopment analysis (DEA) and the Malmquist method. Our results show that the competitiveness position of several Italian regions has not improved over the years under consideration.
