Project description:BackgroundThis paper attempts to evaluate the primary health care system by evaluating health centres in Greece.MethodsMalmquist Index Data Envelopment Analysis is applied to study the total productivity of 155 health centres in Greece during 2016-2018. The data were collected from the Ministry of Health and submitted to quality tests to ensure validity and avoid bias.ResultsThis paper measures the productivity of each of the 155 health centres in Greece and how it shifted during 2016-2018. In addition, the overall productivity change of the 155 health centres over time is calculated and analysed as being due to technical efficiency or technological efficiency. The analysis of the mean values showed a decrease of 0.9% in the overall productivity factor from 2016 to 2017 and a decrease of 5.2% from 2017 to 2018. The overall decrease in the productivity of the 155 health centres was 3.1%. From 2016 to 2018, 59 health centres changed their productivity mainly due to technological change and 91 changed mainly due to technical efficiency change. One health centre showed regression to its total productivity due to equal regression of its technical efficiency and technology.ConclusionsThe method used is nonparametric data envelopment analysis along with the Malmquist index to include panel data in the analysis. Meaningful results were extracted by indicating the number of health centres that improved their productivity, regressed in productivity, or remained constant through the period 2016-2018. This paper may contribute to improving health centres' efficiency and productivity. Furthermore, valuable results can be extracted for the National Health Care System to match available resources that correspond to each health centre's needs, as well as for manager planners and stakeholders in primary health care.

Project description:BackgroundThe pursuit of efficiency and productivity is one of the goals of health systems. In the era of Sustainable Development Goals and particularly the move towards universal health coverage, it is imperative to curb wastage of resources to ensure sustainable access of the population to needed and effective health services without enduring financial hardship. This study aims to assess total factor productivity change of national health systems of 20 countries in the WHO's Eastern Mediterranean Region.MethodsData Envelopment Analysis (DEA)-based Malmquist index is used to assess total factor productivity change and its components - efficiency change and technical change. To assess the robustness of the Malmquist index estimates, bootstrapping was performed. Outputs used are life expectancy at birth for both sexes and infant mortality; while total expenditure on health per capita in international dollars (PPP) is used as a measure of input. Panel data for the period 2003-2014 was extracted from databases of the WHO and the World Bank.ResultsIn all but five countries covered in the study, a decline in the mean total factor productivity is observed during the period 2003-2014. The decline is driven by technical regress. In all countries, the technical change component of the Malmquist TFP index is less than unity (range: 0.896 to 0.945). All countries exhibited growth in efficiency (efficiency change exceeding one) except two countries (Djibouti and Iraq). The growth in efficiency was mainly due to change in scale efficiency. Overall, total factor productivity in the region declined by 3.8%. This was due to a 9.1% decline in technical change, which overshadowed the 5.8% increase in efficiency. Three countries - Libya, Qatar and Yemen - showed a marginal growth in total factor productivity. There was no change in total factor productivity in Kuwait and Lebanon.ConclusionThe decline in total factor productivity over the study period is likely to hamper achieving the targets of Sustainable Development Goal 3 of ensuring healthy lives and promoting well-being for all at all ages. It is recommended that country-level studies on efficiency and productivity of health systems be conducted in order to intensively examine the determinants of inefficiency and productivity decline and implement appropriate interventions that could enhance efficiency and productivity.

Project description:ObjectiveThe increasing demand for total hip arthroplasty (THA) combined with limited resources in healthcare puts pressure on decision-makers in orthopaedics to provide the procedure at minimum costs and with good outcomes while maintaining or increasing access. The objective of this study was to analyse the development in productivity between 2005 and 2012 in the provision of THA.DesignThe study was a multiple registry-based longitudinal study.Setting and participantsThe study was conducted among 65 orthopaedic departments providing THA in Sweden from 2005 to 2012.Outcome measuresThe development in productivity was measured by Malmquist Productivity Index by relating department level total costs of THA to the number of non-cemented, hybrid and cemented THAs. We also break down the productivity change into changes in efficiency and technology.ResultsProductivity increased significantly in three periods (between 1.6% and 27.0%) and declined significantly in four periods (between 0.8% and 12.1%). Technology improved significantly in three periods (between 3.2% and 16.9%) and deteriorated significantly in two periods (between 10.2% and 12.6%). Significant progress in efficiency was achieved in two periods (ranging from 2.6% to 8.7%), whereas a significant regress was attained in one period (3.9%). For the time span as a whole, an average increase in productivity of 1.4% per year was found, where changes in efficiency contributed more to the improvement (1.1%) than did technical change (0.2%).ConclusionsWe found a slight improvement of productivity over time in the provision of THA, which was mainly driven by changes in efficiency. Further research is, however, needed where differences in quality of care and patient case mix between departments are taken into account.

Project description:Rural subjects, the agricultural industrial structure, public services and rural governance are fully empowered by digital villages. This empowerment effectively compensates for the urban-rural digital divide and promotes the equalization of urban-rural income, consumption, education, medical care, and governance. Based on the three-stage data envelopment analysis (DEA) model and Malmquist index, this article conducts an in-depth study of the static and dynamic efficiency trends of digital villages that empower urban-rural balanced development in 31 provinces in China from 2015 to 2020. The results show that comprehensive technical efficiency of 31 provinces is weak DEA effective, and that the scale efficiency is the main factor affecting comprehensive technical efficiency. The educational level, local finance and industrial structure optimization have a significant positive impact on efficiency evaluation, but technological innovation and the urbanization level have a significant negative impact. Total factor productivity shows diminishing marginal utility based on the Malmquist index and its decomposition change. Restricted by the change in technological progress, the efficiency of digital villages in China in enabling urban-rural equilibrium needs to be further improved.

Project description:ObjectivesPublic hospitals in Nepal account for a major share of the total health budget. Therefore, questions are often asked about the performance of these hospitals. Existing measures of performance are limited to historical ratio analyses without any benchmarks. The objective of this study is to explore the trends in inputs, outputs and productivity changes in Nepalese public hospitals from 2011-2012 to 2013-2014.Setting and participantsThe study was conducted among 32 Nepalese public hospitals (23 district level and 9 higher level) for the three fiscal years from 2011-2012 to 2013-2014.Outcome measuresFirst, basic ratio analyses were conducted for the input and output measures over the study years. Then, Malmquist productivity change scores were obtained using data envelopment analysis. Aggregated as well as separate analyses were conducted for district level and higher level hospitals.ResultsReal expenditures of the sampled hospitals declined over the 3-year period from an average of US$ 371 000 in year 1 to US$ 368 730 in year 2 and US$ 328680 in year 3. The average aggregated hospital outputs increased marginally from 8276 in 2011-2012 to 8613 in 2013-2014. The total factor productivity of the study hospitals declined by 6.9% annually from 2011-2012 to 2013-2014. Of the total 32 hospitals, productivity increased in only 12 (37.5%) hospitals and declined in the remaining 20 hospitals. The total factor productivity loss was influenced by a decline in technology change, despite an increase in efficiency.ConclusionsIn general, productivity of the study hospitals declined over the study period. Availability and accessibility of accurate, detailed and consistent measures of hospital inputs and outputs is a major challenge for this type of analysis.

Project description:This paper investigates the effect of firm-level operating flexibility on stock performance during the COVID-19 outbreak in China. We find that firm-level operating flexibility is significantly positively correlated with the cumulative abnormal stock returns that occurred during the event window, and this positive relation is more pronounced in firms in the provinces most affected by the epidemic. This positive relation is also more obvious in firms that have relatively fewer fixed assets. Therefore, our results provide direct empirical evidence that the real options embedded in operating flexibility played an important role during the COVID-19 outbreak.

Project description:This article analyzes the effects of diversification and brand breadth on firm performance for professional service firms (PSFs). The research aim is two-fold. First, we test whether moving into products may put at risk the core resources that sustain PSFs' competitive advantage. Second, we study which branding strategies best match their diversification attempts. Broad (narrow) brands characterize a branding strategy with scarce (plentiful) associations to specific product characteristics. We analyzed trademark portfolios of 47 U.S.-based management consulting firms in the 2000 to 2009 time period. Panel regression results suggest that (1) PSFs always benefit from diversification when they remain pure-service providers; (2) performance is positively related to a strategy of specialized narrow brands.

Project description:This article covers comprehensive data on firm-level corporate governance practices as imposed by the Jordan Securities Commission (JSC). The study includes panel data for 95 non-financial Jordanian listed firms (industrial and service sector) in Amman Stock Exchange (ASE). The time frame used for this study is from 2012 to 2017. Data presented were extracted from the annual reports of each firm. The annual reports had been downloaded from the official website of the ASE. The data can be used easily by the researcher to develop and calculate a corporate governance index that involves thirty-two internal governance attributes and is comprised of three equally weighted sub-indices. The first sub-index which is "Disclosure and Transparency" consists of 15 unique attributes. While the second sub-index, "Board Effectiveness and Composition" consists of 9 unique attributes. The last sub-index which is "Shareholders Rights" consists of 8 unique attributes. Thus, the un-weighted corporate governance index has an important feature that is easily replicated and modified, enabling the researcher to rate firms based on an aggregate index score or by using the sub-indices score also.

Project description:This paper explores the impact of artificial intelligence and industrial robots on firms' export behaviour and divides the impact mechanism into the productivity effect and labour substitution effect. It examines the effect of industrial robots on firms' export value by using Chinese Customs data, Chinese Industrial Firm data and robot data from the International Robot Federation (IRF). The main findings are as follows: Firstly, the impact of artificial intelligence and industrial robots on Chinese firms' export value is generally negative, which means the negative labour substitution effect dominates the positive productivity effect. Secondly, the impact of artificial intelligence varies significantly by industry, and the export value of firms from high-tech industries benefits from the use of industrial robots. Thirdly, the impact of artificial intelligence on firms' export value also varies by time; before 2003, the use of industrial robots showed mainly an inhibiting effect on firms' exports, which turned into a driving effect thereafter, and after 2006, industrial robots began to significantly promote firms' export. Finally, the higher the quality of export products, the more likely the use of industrial robots will be to promote firms' export value, and the higher the capital-labour ratio is, the more likely firms' export value will be to benefit from the use of artificial intelligence and industrial robots. On the basis of these findings, this study proposes promoting the productivity effect to dominate the labour substitution effect through technological progress and the improvement of export product quality.

Project description:This study estimates the contribution of gendered social norms in explaining the gender gap in productivity of unorganised manufacturing firms. Restrictions on mobility and burden of household work mean that female firm-owners primarily operate from their household premises. Using data from unorganised firms operating in the manufacturing sector in India, this paper finds gender gap in firm productivity. The Blinder-Oaxaca decomposition at mean show that despite controlling for size of the firm, assets and other conventional factors, the location of a female proprietary firm within the household premises of the owner explains 19% of the observed gender gap in productivity. The RIF decomposition results show that at the different quartiles, this contribution varies from 19 to 36% of the composition effect. The evidence suggests that the persistence of the gender gap in firm productivity is associated with the persistence of gendered social norms. Supplementary Information The online version contains supplementary material available at 10.1007/s11187-022-00637-2. Plain English Summary Almost 95% of female owned firms in the unorganised manufacturing sector in India operate from within the household premises, due to prevalent gendered social norms. These norms put the responsibility of unpaid household work solely on women and impose mobility restrictions. This paper examines whether restrictive social norms contribute towards the gender gap in firm productivity. I find that that the location of these firms within the household restricts them from expanding, as well as contribute to prevalent the gender gap in productivity and incomes generated from proprietary firms operating in the unorganised manufacturing sector. Newer policies supporting women’s mobility and paid work that supplement conventional policies to improve entrepreneurship are required. However, as social norms involve coordinated actions and fear of sanction in case of noncompliance, these policies would work effectively if they are targeted towards both genders and entire neighbourhoods.
