    (Emerald Group Publishing Ltd, 2021) Dogan, Mustafa Isa; Ozsoy, Volkan Soner; Orkcu, H. Hasan
    Purpose The Covid-19 pandemic spread rapidly around the world and required strict restriction plans and policies. In most countries around the world, the outbreak of the disease has been serious and has greatly affected the health system and the economy. The factors such as the number of patients with chronic diseases, the number of people over 65 years old, hospital facilities, the number of confirmed Covid-19 cases, the recovering Covid-19 cases and the number of deaths affect the rate of spread of Covid-19. This study aims to evaluate the performances of 21 Organisation for Economic Co-operation and Development (OECD) countries against the Covid-19 outbreak using three data envelopment analysis (DEA) models. Design/methodology/approach In this study, the performance of 21 OECD countries to manage the Covid-19 process has been analysed weekly via DEA which is widely used in various practical problems and provides a general framework for efficiency evaluation problems using the inputs and outputs of decision-making units. Findings The analysis showed that 11 countries out of 21 countries were efficient for selected weeks. According to the DEA results from the 20-week review (09 April 2020-20 August 2020), information about the course of the epidemic prevention and the normalization process for any country can be obtained. Originality/value In this study, due to the problem of the discrimination power of DEA, the cross-efficiency model and the super-efficiency model also used. In addition, the output-oriented model was preferred in this study for Covid-19 management efficiency.

    Which Universities Use Their Spaces Efficiently? Efficiency Analysis of the Public University in Turkey
    (Gazi Univ, 2022) Ozsoy, Volkan Soner; Dogan, Mustafa Isa
    The young population is quite high as the birth rate in our country is higher than in other countries. The high number of young people increases the demand for higher education and as a result of this demand, universities gain importance. Thus, the number of universities constituting the educational infrastructure of our country has increased rapidly in recent years. Therefore, it caused that increased the number of newly opened departments and quotas depending on the number of universities. In the face of rapid growth, public investment demands of universities to solve the infrastructure problem have also increased. Despite the establishment of new buildings and classrooms built in the campuses created to fill the quotas, 71 thousand quotas remained empty in 2019. Thus, public resources were used inefficiently due to the fact that the envisaged public investments could not be utilized to the maximum. In this study, the places of the 125 state universities in Turkey were analyzed whether used efficiently. The number of buildings, the number of campuses, and the size of the indoor space they used were taken into consideration for this purpose. In addition, universities were grouped and evaluated according to the provinces where they were located and the years they were founded. While there was no significant difference between the groups according to CCR scores, it was concluded that there was a significant difference between the groups according to BCC scores. The test results show that there is a 5% significance difference between 32 universities established between 2006-2007 and 27 universities established until 1982 and 26 universities established between 1987-1994. The findings show that most of the universities allocated in 2018 use public resources efficiently. Furthermore, this study provides recommendations to decision-makers in evaluating new public investment demands.
