COVID-19 Quarantine Measures Efficiency Evaluation by Best Tube Interval Data Envelopment Analysis
All countries have responded with a wide range of measures to stop the propagation of coronavirus. We apply best tube Interval Data Envelopment Analysis, which allows to evaluate efficiency of quarantine measures using imprecise data. Using the Oxford COVID-19 Government Response Tracker’s (OxCGRT) data and proposed method, we construct timeseries of efficiency assessment of government responses to COVID-19. In addition, we separate all examined countries into several groups with similar patterns of quarantine measures efficiency.

The paper considers the classical Data Envelopment Analysis (DEA) model which is widely applied to efficiency evaluation in a great range of economic branches. Domains of applicability of the model are analyzed. The influence of heterogeneity of the evaluated sample on efficiency values, obtained with the use of DEA is studied. The detailed survey of the ...

The paper proposes a bootstrap methodology for robust estimation of cost efficiency in data envelopment analysis. Our algorithm re-samples "naive" input-oriented efficiency scores, rescales original inputs to bring them to the frontier, and then re-estimates cost efficiency scores for the rescaled inputs. We consider the cases with absence and presence of environmental variables. Simulation analyses ...

Data Envelopment Analysis (DEA) models and Free Disposal Hull (FDH) models were proposed almost simultaneously in the scientific literature. In DEA models, the constraints generate a convex set. For this reason, optimization methods and software are widely used for modeling and computations for these models. Non-convexity of production possibility set of FDH models refrained significantly ...
