An Unbiased Estimator of Peculiar Velocity with Gaussian Distributed Errors for Precision Cosmology [PDF]

open access: yes, 2014
We introduce a new estimator of the peculiar velocity of a galaxy or group of galaxies from redshift and distance estimates. This estimator results in peculiar velocity estimates which are statistically unbiased and that have errors that are Gaussian ...

Malmquist Productivity Analysis Based on StoNED [PDF]

open access: yesSSRN Electronic Journal, 2015
We construct a Malmquist productivity index based on stochastic non-parametric envelopment of data (StoNED) method, and we study how the distributional assumptions in the second StoNED stage affect productivity change and its decompositions. Our discussion show that the distributional assumptions do not affect the estimates of overall productivity ...

Green Biased Technical Change in Terms of Industrial Water Resources in China’s Yangtze River Economic Belt [PDF]

open access: yes, 2020
As a significant ecological corridor from west to east across China, the Yangtze River Economical Belt (YREB) is in great need of green development and transformation. Rather than only focusing on the overall growth of green productivity, it is important

A Sequential Malmquist-Luenberger Productivity Index [PDF]

open access: yesSSRN Electronic Journal, 2009
This study proposes an alternative methodology for measuring environmentally sensitive productivity growth. The rationale of this methodology is to consider the features of technology appropriately by excluding a spurious technical regress based on the macroeconomic perspective. In order to consider this condition and to develop an alternative index, a

The interval Malmquist productivity index in DEA [PDF]

open access: yesIranian Journal of Optimization, 2010
One of the most popular approaches to measuring productivity changes is based on using Malmquist productivity indexes. In this paper we propose a method for obtaining interval Malmquist productivity index (IMPI). The classical DEA models have been before

LDC agriculture: Nonparametric Malmquist productivity indexes [PDF]

open access: yesJournal of Development Economics, 1997
Abstract This paper examines changes in agricultural productivity in 18 developing countries over the period 1961–1985. We use the nonparametric, output-based Malmquist index to examine whether the results from such an approach confirm results from other methods that have indicated declining agricultural productivity in less developed countries (LDCs)
