Efficiency And Productivity

This paper examines the dual efficiency of bioenergy, renewable hydro energy, solar energy, wind energy, and geothermal energy for selected OECD countries through an integrated model with energy, economic, environmental, and social dimensions. Two questions are explored: Which renewable energy alternative is more dual efficient and productive? Which renewable energy alternative is best for a particular country? Data envelopment analysis (DEA) is used for the efficiency evaluation, and the global Malmquist productivity index is applied for productivity analysis. Results indicate bioenergy as the most efficient renewable energy alternative with a 20% increase in average efficiency in 2016 compared to 2012. Renewable hydro energy, wind energy, and solar energy show a 17.5%, 16%, and 11% increase, respectively. The average efficiency growth across all renewable energy alternatives signifies major advancement. Country performance in renewable energy is non-monolithic; therefore, they should customize their renewable energy portfolio accordingly to their strengths to enhance renewable energy efficiency. Renewable hydro appears to have the most positive productivity change in 2016 compared to 2012, while solar energy regressed in productivity due to its scale inefficiency. All renewable energy alternatives have relatively equal average pure efficiency change. The positive trend in efficiency and productivity provides an incentive for policy makers to pursue further development of renewable energy technologies with a focus on improving scale efficiency.

Efficiency And Productivity

Market share on Islamic Insurance is still very small compared to conventional insurance. Islamic insurance companies must be able to compete with conventional insurance in order to increase their market share. Efficiency and Productivity are factors that must be improved so that Islamic insurance can compete with conventional insurance. This study aims to analyze the level of efficiency and productivity of Islamic insurance during the 2016-2018 period. The study was conducted on 48 Islamic insurance companies consisting of 26 Islamic life insurance companies and 22 Islamic general insurance companies. Efficiency analysis use the Data Envelopment Analysis (DEA) approach and productivity analysis use the Malmquist Productivity Index (MPI). The novelty of this study, among others, involves Islamic general insurance in the productivity analysis which has not been studied so far. The results of the analysis shows that the majority of Islamic life insurance and Islamic general insurance are inefficient during the 2016-2018 period. The size of the company which represents the total assets is the factor that have a positive and significant effect on the efficiency value. The results of the productivity analysis shows that the productivity level of both sharia life insurance and general sharia insurance during the 2016-2018 period is influenced by technological change factors.

Human Healthcare

Today, the health industry is known as a human healthcare service required to develop the economy ensuring life and health for people of each country. Applications of science and technology to create tools, equipment, and drugs always focus on applying a lot to healthcare and getting top priority. Therefore, the health sector always has the most important role in providing community health, treating diseases, ensuring life, and maintaining human health to study and work. Besides, the health sector contributes a lot to the socio-economic development of each country. In this study, the authors use data on pharmaceutical enterprises' business situation in 2012-2017 to process, analyze and evaluate the business performance of all these businesses from 2012 through 2017 by using the Malmquist productivity index model of data envelopment analysis. This study has achieved positive results and high applicability; the authors used specific indexes to evaluate the efficiency of use and changes in technique and technology at pharmaceutical companies, which helps managers have both broad and detailed insights into the production and business activities of these enterprises.

Efficiency And Productivity

The Financial Master Plan (2001- 2010) aims to enhance the capacity of banking industry so that higher effic iency and productivity can be reaped in the future. This study seeks to determine the impact of merger on the efficiency and productivity ofcommercial banks in Malaysia for the period 1995 until 2005. The study uses a non-parametric approach, nam ely DEA (data envelopment analysis?) to estimate the efficiency scores and to construct the Malmquist productivity index. To enable this estimation, three bank inputs and outputs are used. Amongst the findings are those banks exhibit higher efficiency score after the merger and thefo reign banks are more efficient than the local banks. Productivity of the banks is calculated in both periods, before and after the merger: The results show that, it is the local banks that have improved the most after the merger. The main source of productivity is technical change or innovation. The findings support the existing policy of having larger domestic banks in term of size.
