A non-parametric investigation of supply side factors and healthcare efficiency in the U.S
Springer Science and Business Media LLC - Tập 54 - Trang 59-74 - 2020
Richard Gearhart, Nyakundi Michieka
In this study, the supply-side factors affecting healthcare efficiency in the U.S are studied using data between 2010 and 2017. The recently developed non-parametric order-m estimator is used for the analysis. Results suggest that the U.S. has output production that is 87.6-percent of the expected maximum amount, with life expectancy being 3 years too short given healthcare spending and education ...... hiện toàn bộ
An Analysis of Differences in Earnings Between Small and Large Commercial Banks
Springer Science and Business Media LLC - Tập 20 - Trang 97-114 - 2003
P.A.V.B. Swamy, George S. Tavlas, Thomas J. Lutton
This paper introduces a simple, yet rich, measure of efficiency changes based on the revenue-generating-ability (RGA) principle. Using this principle, we explain the connections between efficiency changes and the variables, such as pretax profits, interest expense, non-interest expense, profit margins, loan loss provision, and asset quality. These connections are used to explain earnings differenc...... hiện toàn bộ
Shadow profit maximization and a measure of overall inefficiency
Springer Science and Business Media LLC - Tập 27 - Trang 231-236 - 2007
Subhash C. Ray
Determining the profit maximizing input–output bundle of a firm requires data on prices. This paper shows how endogenously determined shadow prices can be used in place of actual prices to obtain the optimal input–output bundle where the firm’s shadow profit is maximized. This approach amounts to an application of the Weak Axiom of Profit Maximization (WAPM) formulated by Varian [(1984) The Non-pa...... hiện toàn bộ
Explaining firms efficiency in the Ivorian manufacturing sector: a robust nonparametric approach
Springer Science and Business Media LLC - Tập 37 Số 2 - Trang 155-169 - 2012
Nolwenn Roudaut, Anne Vanhems
On functional form representation of multi-output production technologies
Springer Science and Business Media LLC - Tập 33 - Trang 81-96 - 2009
Rolf Färe, Carlos Martins-Filho, Michael Vardanyan
The introduction of directional distance functions has given researchers an alternative to Shephard distance functions. In this paper we conduct a Monte Carlo study to investigate the performance of distance functions as an approximation for models of technology. Our results indicate that quadratic representations of technology have better approximation properties than translog parameterizations.
Productivity efficiencies in Ukrainian polyclinics: lessons for health system transitions from differential responses to market changes
Springer Science and Business Media LLC - Tập 29 - Trang 103-111 - 2008
Patrick M. Bernet, Michael D. Rosko, Vivian G. Valdmanis, Anatoly Pilyavsky, William E. Aaronson
Ukraine’s recent elections revealed deep divisions between eastern regions, which favored central economic planning, and western regions, which preferred more free market reforms. This study compares polyclinics in Ukraine to see if the inflexibility of Soviet-style planned economies results in lower economic efficiency in eastern regions. Using data from two geopolitical regions, Data Envelopment...... hiện toàn bộ
Public Infrastructure Investment and Efficiency in Italian Regions
Springer Science and Business Media LLC - - 2006
Camilla Mastromarco, Ulrich Woitek
Capital use intensity and productivity biases
Springer Science and Business Media LLC - Tập 37 - Trang 59-71 - 2011
Matthew A. Andersen, Julian M. Alston, Philip G. Pardey
Measures of productivity growth are often pro-cyclical. This paper focuses on measurement errors in capital inputs, associated with unobserved variations in capital utilization rates, as an explanation for the existence of pro-cyclical patterns in measures of productivity. Recently constructed national and state-specific indexes of inputs, outputs, and productivity in U.S. agriculture for 1949–200...... hiện toàn bộ
Boundary problems with the “Russell” graph measure of technical efficiency: a refinement
Springer Science and Business Media LLC - Tập 37 Số 3 - Trang 239-248 - 2012
Levkoff, Steven B., Russell, R. Robert, Schworm, William
In an influential paper, Färe and Lovell (J Econ Theory 19:150–162, 1978) proposed an (input based) technical efficiency index designed to correct two fundamental inadequacies of the Debreu-Farrell index: its failure to satisfy (1) indication (the index is equal to 1 if and only if the input bundle is technically efficient) and (2) weak monotonicity (an increase in any one input quantity cannot in...... hiện toàn bộ
Facet analysis in data envelopment analysis: some pitfalls of the CRS models
Springer Science and Business Media LLC -
Ole Bent Olesen, Niels Christian Petersen
AbstractThe nonparametric estimator of the Extended Facet reference technology for the Constant Returns to Scale case has attracted some attention, because the associated production frontier by construction does only include strongly efficient faces of maximal dimension, or strongly efficient faces that are part of such strongly efficient faces of maximal dimension...... hiện toàn bộ
