In the model setting of multiregional macroeconomic research, constant return on scale all production functions and free flow factors cannot be combined. Otherwise, potential theoretical conflict, that is, problem contradiction equations, may arise. If there is a unified capital interest rate in market regions remains unchanged, it necessary to set restrictions labor force order realize differe...

The returns to education remain a central concern for development policy. In developed countries there is evidence that the returns to education have been rising. Evidence for changes over this period for developing countries is limited. In this paper we use data from Kenya and Tanzania to estimate returns to education for manufacturing workers and examine how these returns have changed from 19...

Abstract The current study aims to investigate the relationship between Iran’s Targeted Subsidies Plan and the stock returns of listed companies on the Tehran Stock Exchange (TSE). Stock returns is obtained from the indices of three industries: pharmaceuticals, chemicals, and machinery and equipment. Moreover, the present research uses gold price and dollar price as control variables. The Targe...

Using a sample of 21 OECD-countries we measure productivity in top-edge economic research by using data envelopment analysis (DEA). DEA is a tool for evaluating relative efficiency and is widely used when there are multiple inputs and outputs and one lacks a specific functional form of a production function. The publications in 10 economics journals with the highest average impact factor over t...

introduction: due to increased costs of health sector, much effort has been done to compare the performance of hospitals and measure their efficiency in recent years. the purpose of this study was to evaluate the relative efficiency of public and private hospitals in qom during 2007 using data envelopment analysis (dea) approach. methods: this was an applied and analytic study. the study popula...

Background: Despite the potential benefits of virtual reality technology in physical rehabilitation, only a few studies have evaluated the efficacy of this type of treatment in patients with neck pain.Objective: The aim of this study was to compare the effects of virtual reality training (VRT) versus conventional proprioceptive training (CPT) in patients with neck pain.Methods: Forty four parti...

In this article, we will estimate efficiency amountof decision-making unit by offering the continuous piecewise polynomialextrapolation and interpolation by CCR model input-oriented on the assumptionthat it is constant returns to scale in different times. And finally, we willestimate efficiency amount of decision-making unit indifferent times byoffering an example.
