INDUSTRY‐LEVEL PRODUCTIVITY MEASUREMENT AND THE 2008 SYSTEM OF NATIONAL ACCOUNTS

The 2008 System of National Accounts recognizes capital services as the conceptually correct way to measure the input of capital into production. This allows setting up an integrated system of industry‐level and aggregate productivity accounts that are consistent with the 2008 SNA. The paper discusses the new aspects in the 2008 SNA and sets out such an integrated system, based on Jorgenson's aggregate production possibility frontier and gross output‐based industry productivity measures. Recent results for industry productivity measures for the United States complete the picture.     

Japan's productivity stagnation: Using dynamic Hsieh–Klenow decomposition

This study provides a new perspective on Japan's stagnant aggregate productivity by extending the Hsieh and Klenow (2009) framework to account for productivity growth, entry and exit, and product variety change. We measure the technical efficiency (TE) and allocative efficiency (AE) by the aggregate production possibility frontier and the distance from the frontier, respectively. We apply our approach to establishment- and firm-level data sets from Japan and find that the AE among survivors declined during the banking crisis period, while the TE declined during the global financial crisis period.     

Comment on “Unwrapping some euro area growth puzzles: Factor substitution, productivity and unemployment”

This paper estimates the factor elasticity of substitution of the aggregate production function and then uses these estimates to resolve two puzzles relating to the Euro Area. The paper is novel in three ways: First it uses the CES production technology in the empirical strategy to understand real world economic phenomena; second it uses a frontier empirical methodology; and third it uses a new dataset.     

Creative destruction on the Chechen frontier?

The economic performance of Chechnya is examined for the first time using an aggregate stochastic frontier production function method. The 15 sectors of the economy are found to be quite inefficient in the use of capital and labour to produce aggregate output. Extensive growth is likely to continue though at a lower rate as federal subsidies from Moscow end. Intensive growth is unlikely given the lack of foreign investment and the authoritarian political system. Some evidence for the emergence of a market economy is found, suggesting that Kadyrov has overseen an economic transition.     

INFRASTRUCTURE AND PRODUCTION EFFICIENCY: AN ANALYSIS ON THE KOREAN MANUFACTURING INDUSTRY

This study estimates an aggregate production function of manufacturing industry using panel data of 11 Korean regions covering 1977–1992. While the previous studies regard infrastructure as a direct input for production, the present study proposes that infrastructure has an effect on actual output by enhancing technical efficiency thereby, reducing the gap between maximum potential output and actual output. To investigate the relationship between infrastructure and technical efficiency, a stochastic frontier approach is applied to Korean manufacturing industry. Confirming the presence of substantial technical inefficiency in production, this study shows that an increase in infrastructure reduces the technical inefficiency level. The study also finds that, contrary to expectation, the industrialized regions are less efficient than the less industrialized ones. (JEL O20, H54, C23)     

A robust approach to the measurement of Farrell efficiency

Measurement of efficiency of the frontier production function by Farrell's convex hull method is generalized here in two aspects. One develops a minimax method of estimation by following the Chebyshev principle and the other develops a dummy-variable method of stratifying the entire data set before ordinary regressions are performed to estimate the production frontier. An empirical application to educational production functions illustrates these methods.     

Patterns of technical change: a geometrical analysis using the wage–profit rate schedule

In this paper we examine some basic stylized facts of economic growth according to the modern restatement of the classical theory of income distribution. In particular, we make use of a wage–profit frontier in order to explore the patterns of technical change experienced by a set of 18 industrialized economies, during the last 40 years. Our main purpose is to document the evolution of technical change. Using empirical evidence from the Italian industry, we also make an attempt to provide an explanation to data from a classical perspective, alternative to the standard approach founded on the aggregate production function.     

The Measurement of Dynamic Productive Efficiency

Measuring dynamic productive efficiency from observed input-output data raises several new issues which are absent in the static production frontier studies. The adjustment cost approach is developed here as an interface between the static and the dynamic frontier studies, and the non-parametric method of Farrell developed for static efficiency is extended for the specification of a dynamic production frontier.     

Intrasectoral structural change and aggregate productivity development: robust stochastic nonparametric frontier function estimates

This paper investigates the sources of total factor productivity growth in the German manufacturing sector during 1981–1998. Decompositions of aggregate productivity growth are used to identify the effects of structural change and entry–exit on aggregate productivity growth. We find a substantial rise in productivity growth after the German reunification. The bulk of this rise can be attributed to structural change and entry–exit. Two methodological refinements are implemented. The first refinement is the application of robust stochastic nonparametric approaches to frontier function analysis, and the second is the calculation of bootstrap confidence intervals for the components of the productivity decompositions.     

Public and private inputs in aggregate production and growth: a cross-country efficiency approach

In a cross section of OECD countries, we replace the macroeconomic production function by a production possibility frontier, total factor productivity being the composite effect of efficiency scores and possibility frontier changes. We consider, for the periods 1970, 1980, 1990 and 2000 one output – GDP per worker – and three inputs – human capital, public physical capital per worker and private physical capital per worker. We use a semi-parametric analysis, computing Malmquist productivity indexes, and we also resort to stochastic frontier analysis. Results show that private capital is important for growth, although public and human capital also contribute positively. A governance indicator, a nondiscretionary input, explains inefficiency. Better governance helps countries to achieve a better performance. Nonparametric and parametric results coincide rather closely on the movements of the countries vis-à-vis the possibility frontier and on their relative distances to the frontier.     

Trade, technology transfer and national efficiency in developing countries

This paper simultaneously explores the determinants of the developing countries’ production frontier and these countries’ ‘efficiency’ in using the available resources and technology. In doing so it allows for the transfer of (industrial country) technology in determining the frontier and for international trade's influence on absorptive capacity and national efficiency levels. Stochastic frontier analysis is used to model the production frontier for 57 developing countries for the period 1970-1998, to measure cross-country and temporal differences in efficiency levels and to explain the differences in efficiency levels. The results indicate significant differences in efficiency levels across countries and regions and movement over time, and an important influence of trade and trade policy in raising output both through technology improvements embodied in imported capital goods and by inducing efficiency improvements.     

测度政府技术效率的模型与方法比较研究

技术效率是在产出规模不变,市场价格不变的条件下,按照既定的要素投入比例所能达到的最小生产成本占实际生产成本的百分比。政府技术效率是广义的政府绩效或效率的一个部分,它是政府提供公共服务过程中能够测度的政府投入与政府产出之间的比例关系。测度政府技术效率主要的模型与方法有非参数前沿法和参数前沿法。非参数前沿法主要包括数据包络法分析（DEA）和自由处置包（FDH）,而参数前沿法主要包括随机前沿法（SFA）、模糊边界法（TFA）和确定性前沿法（DFA）。通过建立模型科学对政府技术效率进行评估与测度可提高政府各个方面的科学性和有效性,从而促进政府技术效率的提高。     

Economic versus physical input measures in the analysis of technical efficiency in fisheries

The measurement of technical efficiency requires the estimation of an appropriate production frontier. This is based on a set of inputs that are assumed to influence the level of output. Deviations from this frontier production function are separated into random variation and inefficiency. However, mis-specification of the production function through the use of inappropriate input measures may result in a bias in the measures of inefficiency. In fisheries, production is generally assumed to be a function of stock size, fishing time and the level of physical inputs employed. Defining the appropriate levels of physical inputs, however, is not straightforward, and several alternative measures are available. While economic measures of capital are more intuitively appealing, physical measures are generally readily available and hence less costly to collect. In this study, technical efficiency is measured for three fleet segments operating in the North Sea using three different gear types. The effects of using different measures of capital in the production frontier on the efficiency estimates are examined.     

Micro-heterogeneity and aggregate productivity development in the German manufacturing sector

A decomposition of aggregate productivity growth of German manufacturing firms that pertain to 11 different industries at a roughly two-digit level observed over the period 1981–1998 is performed. Productivity is measured by a nonparametric frontier function approach. The decompositions of productivity allow for an explanation of the aggregate outcomes by the quantification of the effect of structural change and the contributions of entering and exiting firms. Our results show that these forces drive aggregate productivity to a considerable extent. Remarkably, the large productivity improvements after the German reunification are mainly driven by structural change.

Network infrastructure spillover in private productive sectors: evidence from Spanish high capacity roads

Interest in public infrastructure research has been a subject of increasing concern to economists and policy-makers. This article aims at analysing the locational impact of the high capacity roads (HCR) on the Spanish private economic activity from 1970 through 1998, given that this is one of main infrastructure-based development strategy undertaken in Spain in this period. In a stochastic frontier production-function framework, we allow for modelling of provincial heterogeneity through the existence of different efficiency levels in the territorial units. Results show HCR spillovers between geographically close provinces and between provinces displaying similar socio-demographic characteristics and government size. To the extent that the magnitude and sign of these impacts differ across sectors a reasonable explanation of the limited impact of HCR on aggregate private production could be made. The presence of a negative spillover effect in the industrial and business service sector suggests that Spanish provinces may have used HCR capital as a competitive tool for attracting factors of production leading to a rearrangement in these economic activities.     

The CES Production Function,the accounting identity,and Occam's razor

This paper reconsiders the argument that empirical estimations of aggregate production functions may be interpreted merely as statistical artefact. The reason is that Occam's razor, or Herbert Simon's principle of parsimony, suggests that the aggregate production function, together with the side equations derived from the usual neoclassical optimizing conditions, simply reflect the underlying accounting identity that value added definitionally equals the wage bill plus total profits. This argument is illustrated with respect to the empirical evidence presented by Arrow, Chenery, Minhas and Solow (Review of Economics and Statistics, XLIII, 225-50, 1961) and which led them to derive the Constant Elasticity of Substitution aggregate production function. It is shown that their results are more parsimoniously explained with reference to the underlying accounting identity than to any technological relationship.     

外商直接投资和经济增长的关系研究

理论研究普遍认为外商直接投资对经济增长产生了积极的影响,但对外商直接投资如何影响新兴工业化国家的发展过程的具体机制却研究甚少。本文从新兴工业化国家的视角提出并验证了有关外商直接投资对经济增长作用的两个假设:(1)外商直接投资有利于减小国内生产的非效率,是提高生产技术效率的推动器;(2)外商直接投资有利于加快国内技术进步,是生产前沿的移动器。因为这种双重作用,所以外商直接投资是新兴工业化国家赶超世界发达国家的一个重要因素。中国过去几十年经济快速的发展为验证这两个假设提供了一个理想的范例。     

An analysis of the impact of unionization on efficiency: evidence from a meta-frontier analysis

This article examines the impact of unions on the efficiency of establishments in the manufacturing industry by comparing the results from two different empirical strategies: stochastic frontier analysis (SFA) and meta-frontier analysis (MFA). While SFA concludes that union establishments show higher technological efficiency, the results are the opposite when estimating production functions with MFA. In SFA, unionized establishments appear to be more efficient because they remain closer to their own production frontier; however, in MFA – where groups with heterogeneous technology can be compared – we find that nonunionized establishments are more efficient because they are closer to the meta-frontier than their unionized counterparts.     

Estimating technical change by nonparametric methods

A nonparametric method using dynamic data envelopment analysis is developed here to specify and estimate a dynamic production frontier. By this technique technological progress measured by the time shift of the production frontier and the scale economies measured by increasing returns to scale are estimated from the observed input output data, which may sometimes be nonstationary. An application to US computer industry exhibits substantial technological progress and scale economies over the period 1987–1998.     

Differentiable Technology,the Curvature of the Profit Function,and the Response of Supply to Own-Price Changes

The author establishes a property of supply for a competitive firm: Assuming differentiability of the production frontier, linearly independent price vectors have disjoint image sets under the supply mapping. This property supports the main results. First, the author drew a simple proof of McFadden's proposition that differentiability of the production frontier is necessary and sufficient for strict quasiconvexity of the profit function. This proposition rules out linearity of the profit function on any subset of price domain, in turn ruling out supply and input- demand functions that are constant and have zero values for all price effects. Second, for discrete price changes, own-price effects in supply are strictly positive, assuming a differentiable technology. In this context, strict convexity of the production set is irrelevant. The author indicates implications for cost and demand theory.
