The new approach to parity of prices is the subject of article. The base of this approach is estimation of parameters of model for comparison of prices between countries. The disparity of the prices is defined as a sharp deviation of the price from the parity. Milk is taken as an example. The model on which the parity of the prices is defined, has been developed for the longterm prices fore- casting. The realization of the certain scenario of development of a national economy is a base of such forecasting
We address the external effects on public sector efficiency measures acquired using Data Envelopment Analysis. We use the health care system in Russian regions in 2011 to evaluate modern approaches to accounting for external effects. We propose a promising method of correcting DEA efficiency measures. Despite the multiple advantages DEA offers, the usage of this approach carries with it a number of methodological difficulties. Accounting for multiple factors of efficiency calls for more complex methods, among which the most promising are DMU clustering and calculating local production possibility frontiers. Using regression models for estimate correction requires further study due to possible systematic errors during estimation. A mixture of data correction and DMU clustering together with multi-stage DEA seems most promising at the moment. Analyzing several stages of transforming society’s resources into social welfare will allow for picking out the weak points in a state agency’s work.
