“…Very few studies handled the measurement of efficiency in hospitals outside Europe and the US. For exceptional examples are: Canada (Chowdhury, Zelenyuk, Laporte, & Wodchis, 2014), Japan (Kawaguchi, Tone, & Tsutsui, 2014), China (Yang & Zeng 2014, Xu et al 2015, Turkey (Sahin & Ozcan 2000, Ali 2016), Iran (Hajialiafzali, Moss, & Mahmood, 2007), and the Philippines (Li et al, 2016). Few studies applied DEA in the developing countries.…”

Jordan is committed to providing healthcare services for more than a million refugees coming from bordering countries in the last five years and face increasing demand for the services of public hospitals. Their efficiency is a key success factor to manage the unique and complex context effectively. This research investigated the technical and scale efficiency of the Jordanian Public Hospitals. The study applied constant and variable returns to scale input-oriented DEA models to rank hospitals and allocate the factors associated with inefficient operations. The work tested 27 general public hospitals from 2010 to 2014, in total, 135 observations were examined with respect to four input-measures and three output-measures. The output-measures characterize three functional areas; inpatient, outpatient, and ambulance and emergency departments. Further, decomposing the technical efficiency allowed considering for scale effects. Findings revealed that 25 observations out of 135 ones were efficient and constructed the efficient frontier. Eight hospitals in 2014 were on the frontier, but weakly efficient and all suffered slacks. Targets and reference sets were identified to guide improvements. Hospitals were sorted into five performance patterns; promising, declining, stable good, stable poor, and unstable. The number of physicians and outpatient services recorded high slacks. On average, 2013 scored the best performance. Scale analysis shows that a capacity of 160 beds is an optimal production size in Jordan. Inefficient and weakly efficient hospitals can target areas of opportunities for performance improvements. The efficiency of Public hospitals in Jordan was not investigated since 1992. The study was limited to public hospitals from 2010 to 2014.

The few studies on COVID-19’s impact on stock market efficiency have reached mixed conclusions. However, the findings lean towards a negative impact, no studies have assessed market efficiency when returns increase in the existing capacity of COVID-19 cases, exchange rates and inflation rates. This study uses data envelopment analysis (DEA) and the DEA-adjusted estimator. We finally adopt the cross and time product ratios to determine the persistence of stock market efficiency. We find that the COVID-19 pandemic severely impacted the efficiency of African stock markets in 2021 and that the efficiency of African stock markets persists only in the short run. These findings are relevant to investors seeking to diversify their portfolios during pandemics and to regulators of African stock markets. Global investors should diversify their portfolios with African stock markets to mitigate the impact of pandemics on their investments. To reap the benefits of diversification, investors should invest in efficient African markets during pandemics and sell stocks in inefficient markets in the short run. In addition, regulators of African stock markets should adopt technologies that aid in the flow of information among investors.
