Convergence and productive e$ciency in fourteen OECD countries: A non-parametric frontier approach
نویسندگان
چکیده
This paper explores the use of a non-parametric frontier approach to analyse multi-factor productivity across time and countries. We argue that conventional measures of total factor productivity involve some restrictive assumptions that might bias the results. A non-parametric approach avoids these assumptions. The model uses linear programming techniques to examine the productivity catching-up in 14 OECD countries over the 1970}1990 period, under the assumption of variable returns to scale. We "nd evidence of convergence, even if at quite di!erent speeds, for total industry, for manufacturing and for services. ( 2000 Elsevier Science B.V. All rights reserved.

Productivity Breakdown of the Information Technology Industries across Countries
In this paper, we measure productivity growth of the information technology (IT) industries in fourteen OECD countries over the thirteen-year period of 1978 through 1990. The IT industries are the providers of IT capital goods, and this macro-level analysis seeks to find out how efficiently IT capital goods are produced. The basic unit of analysis employed is the Malmquist Total Factor Producti...
متن کاملStochastic Non-Parametric Frontier Analysis
In this paper we develop an approach that synthesizes the best features of the two main methods in the estimation of production efficiency. Specically, our approach first allows for statistical noise, similar to Stochastic frontier analysis, and second, it allows modeling multiple-inputs-multiple-outputs technologies without imposing parametric assumptions on production relationship, similar to...
متن کاملProductivity Change in the Telecommunications Industries of 13 OECD Countries
This paper focuses on the evolution of productivity in the telecommunications industries for 13 OECD countries over the period 1979-1998. It uses Data Envelopment Analysis, a non-parametric approach that allows decompositions of changes in productivity into variations in efficiency and technical change. Moreover, it tests the existence of convergence in labor and total factor productivity level...
متن کاملTesting the Convergence Clubs Hypothesis among MENA Countries
T his paper is to study the convergence of per capita income. Convergence clubs hypothesis is one of the forms of convergence hypotheses, implying that countries with the same initial level of economic development, technology, and government policies, tend to be similar in per capita income and thus have a tendency to cluster around a small number of poles. In order to test the hypot...
