The escalating competitiveness within the healthcare industry and the growing financial burden necessitate public hospitals, which serve as crucial entities in this sector, to enhance the efficiency of their resource utilization. Public hospitals are mandated to determine their levels of activity, utilize cases of inactivity as benchmarks, and formulate strategies to ensure their active engagement. This study focuses on doing a performance and cost analysis of health institutions affiliated with the Turkish Republic Ministry of Health, namely the public hospitals in the Bakirköy area of Istanbul. The evaluation of activity and productivity is practiced to assess the performance and cost-effectiveness of these institutions. According to the data enveloping analysis method, it is evident that approximately 80% of health institutions affiliated with the Istanbul Bakirköy district public hospitals Union general secretary are fully operational and efficient. However, 20% of these institutions face challenges in effectively utilizing their resources. It is well acknowledged that teaching and research hospitals exhibit high levels of productivity and activity since they effectively utilize their resources in a sensible manner.

In the arena of economic analysis, the wealth of a nation is getting more and more attention to be a better indicator to evaluate the status of an economy. This paper had studied the aggregate household wealth of different nations of the world, 106 countries, for the year 2009-2018. During these years, only two countries of the world, China and the USA have managed to increase their wealth tremendously over the last decade while others experienced a slow pace in the growth of wealth. To satisfy the query of how efficient these countries were in maximizing their wealth, a stochastic frontier approach (SFA) has been used to predict the technical efficiency dependent variable and then generalized methods of moments (GMM) and other models have been used to find out the determinants of this efficiency. The study had come up with the result that land, labor, and capital mainly contributed to the output of wealth maximization while past year level of efficiency, export, and import played the main roles in determining the wealth maximizing efficiency status of a nation. It is found that there is a negative relationship between past-year efficiency with current years and the more a country imports, the less efficient the country is while the more it exports, the more efficient the country is in maximizing wealth.
