地区劳动生产率差异分解与条件收敛——基于产业经济的结构分析

运用偏离-份额法,本文将1985-2008年地区劳动生产率差异分解成产业结构效应、纯生产率效应和配置效应。实证发现,产业结构效应对解释东部和西部地区劳动生产率差异具有突出作用;而纯生产率效应较低是中部地区劳动生产率低于全国平均水平的最重要原因。在此基础上,基于条件收敛分析框架,我们用SUR模型研究发现,地区间存在着的产业结构收敛、产业内纯生产率收敛是地区劳动生产率收敛的内在原因,并且产业内纯生产率收敛是其最主要的组成成分。     

The relative weight of manufacturing and services in Europe: An innovation perspective

This paper uses an innovation-based taxonomy of both manufacturing and service industries to assess the role of the process of structural change of the last 25 years on the rate of productivity growth in Europe, US and Japan. The empirical analysis exploits the shift-share methodology for a decomposition of aggregate labor productivity growth. A modified version is applied, that allows to interpret whether employment has shifted to higher or lower productivity sectors. The results are discussed in light of the role that the different industries play according to the innovation-based taxonomy.     

Physical productivity of new firms: it is not as high as it appears

This paper argues that the physical productivity of new firms is not as high as it is measured with conventional approaches. The overestimation is due to two reasons, both of which are related to the underestimation of production inputs of new firms. On the extensive margin, while conventional approaches implicitly assume the share of production costs in the total costs is the same for all firms, new firms spend a larger share of their costs on production. On the intensive margin, conventional approaches usually use capital stock as the proxy for capital input and tacitly assume a constant ratio between capital service and capital stock, whereas new firms tend to use their capital more intensively. Failure to incorporate the two facts leads to economically significant inflation in the measured physical productivity of new firms.     

要素流动与生产率增长研究——对广东省“空间结构红利假说”的实证分析

在采用"永续盘存法"估计广东省三次产业和各市资本存量的基础上,利用"偏离—份额法"分解了广东省产业结构和空间结构的生产率增长效应,并发现生产率的增长主要来源于劳动力的结构效应,尤其是静态转移效应;而内部增长效应在多数阶段都产生了较大的抑制作用。劳动力要素的流动所带来的不管是产业结构还是空间结构的改变都表现出了"结构红利"现象,而资本表现出的"结构红利"不明显,甚至还产生了"结构负利"。     

出口、产业结构和生产率变动：来自制造业与生产者服务业的证据

经济转型需要生产和就业结构的根本改变。生产率提高带来资源尤其是劳动力资源的优化配置。然而,这种优化配置的出现在不同行业具有不同的特点,并且其影响因素也各不相同。本文利用2001-2007年的数据采用份额转换方法测定了制造业和生产者服务业的生产率变化以及劳动力资源的配置变化,然后,从多个层面分析了出口等因素对制造业和生产者服务业的影响,其中出口对资源配置的影响在中、高技术的制造业和生产者服务业中有较积极的影响。     

Luenberger and Malmquist Productivity Indices: Theoretical Comparisons and Empirical Illustration

This contribution establishes, from a theoretical viewpoint, the relations between the Malmquist productivity indices, that measure in either input or output orientations, and the Luenberger productivity indices, that can simultaneously contract inputs and expand outputs, but that can also measure in either input or output orientations. The main result is that a Malmquist productivity index overestimates productivity changes, since it provides productivity measures that are nearly twice those given by the Luenberger productivity index looking for simultaneous contractions of inputs and expansions of outputs. This relationship is empirically illustrated using data from 20 OECD countries over the 1974–97 period.     

Optimal Growth with Endogenous Technical Progress: Hicksian Bias in a Macro Model

If productivity growth is endogenous, the question of whether to allocate some resources to increase the efficiency of capital needs to be examined in spite of the conventional wisdom that only Harrod-neutral technical progress is compatible with the steady state. This paper describes the crucial role that the production technology and research sectors play in determining the allocation of resources for accumulating physical capital and enhancing the productivity of inputs. We develop a model of biased growth, where, even in the steady state, the efficiency of capital and labour are increasing due to the allocation of resources to the research sector.

Second thoughts on development accounting

The relative roles of factor inputs and productivity are estimated in explaining the level of economic development. For a large sample of countries, it is shown that international differences in factor inputs account for between two thirds and three quarters of international differences in output per worker if alternative identifying productivity assumptions and a quality-adjusted measure of human capital are employed. For a sample of OECD countries, it is found that all differences in output per worker can be attributed to differences in factor inputs, leaving no role for international productivity differences. This result supports the reasoning of a traditional neoclassical growth model.     

Farmer organizations and maize productivity in rural Burkina Faso: The effects of the diversion strategy on cotton input loans

This study analyzes the impact of the diversion strategy of cotton inputs on maize productivity among farmer organization (FO) members in Burkina Faso, based on an endogenous treatment effect model. This impact is assessed by measuring the effects of the producers’ strategy of using part of their cotton inputs for growing other crops, such as maize. The data from a 2014 multisectoral survey in Burkina Faso were used. The main result is that maize productivity is 59.11% lower for FO members who divert their cotton inputs. We suggest the development of financing systems for cereals, similar to those in the cotton sector, and the establishment of monitoring the use of input credits.

The Catching-up of Japanese with German Industries: Production Organization, Infrastructure, and R&D

This paper presents an empirical productivity comparison between Japan and Germany, focusing on organization, R&D and infrastructure. Time-series datasets from the auto vehicle and electronic engineering industries are used to demonstrate the reversal in productivity advantage from Germany to Japan at around 1980. It is argued that Japanese productivity gains arose from a better infrastructure and from cost-reducing innovations such as lean production methods. An econometric model determines the causes for the observed differences in the quantities of inputs used. It shows that frequent external procurement in Japanese manufacturing has shifted the factor inputs from labor and capital to materials, a result in line with the philosophy of lean production.     

Adoption Of Advanced Manufacturing Technology And Firm Performance In The Netherlands

This paper presents characteristics of firms that employ advanced manufacturing technology (AMT), explores the pattern of adoption of such technology, and traces the effects of adoption on the evolution of employment and productivity. The study uses linked firm-level data on production, factor inputs and on advanced manufacturing technology. It is found that the percentage of firms that employ advanced technology increases with higher labor productivity, higher export-sales ratios, and especially larger firm sire. Corrected for interactions, however, only initial size and the initial capital-labor ratio aid in predicting adoption of AMT. Conditional on adoption of AMT it is seen that intensity of advanced technology inputs decrease with firm sire and with labar productivity. Finally, firms which employed AMT in 1992 show higher average growth rates of (toral factor) productivity and employment between 1985 and 1991.

Why are initial estimates of productivity growth so unreliable?

This paper argues that initial estimates of productivity growth will tend to be much less reliable than those of most other macroeconomic aggregates, such as output or employment growth. Two distinct factors complicate productivity measurement. (1) When production increases, factor inputs typically increase as well. Productivity growth is therefore typically less variable than output growth, meaning that measurement errors will tend to be relatively more important. (2) Revisions to published estimates of production and factor inputs tend to be less highly correlated than the published estimates themselves. This further increases the impact of data revisions on published productivity estimates.To assess the extent of these problems in practice, we detail the importance of historical revisions to the most commonly-used measures of US aggregate productivity growth, expanding on previous empirical work by Aruoba (2008) and Anderson and Kliesen (2006). We find that such revisions have contributed substantially to policymakers’ forecast errors for US productivity growth.     

Natural Resources and Missing Inputs in International Productivity Comparisons*

Standard theory for cross-country productivity comparisons assumes all countries use the same factor inputs in production. This assumption is violated when including natural resources, such as oil, gas and gold, because countries do not extract the full set of resources. In this paper we propose a solution by viewing it as a “missing goods” problem and assigning missing inputs a reservation price equal to the world resource price. We show that this has a substantial impact on relative productivity levels for countries heavily reliant on natural resources for generating their income. Under our new productivity measure, resource-rich countries are no longer uncommonly productive.     

要素流向高增长行业能实现产业升级吗——基于制造业的分析

加大对高生产率(或高生产率增长率)行业的要素投入常被各地政府视为调整经济结构、实现产业升级的最有效措施之一。然而,本文通过使用偏离-份额法对制造业生产率的研究发现:总体上,外部的要素投入和转移并未促进、甚至抑制了制造业效率的提高;行业内部的生产率增长才是制造业生产率提高的最主要源泉;内生性的创新比外生性的要素投入更有利于推动制造业的效率提高;疏通要素流通渠道、融入全球价值链高端行业、完善内部创新的外部环境等,将是我国"十二五"期间实现制造业产业升级和经济结构战略性调整的关键。     

International Organization of Production with Heterogeneous Firms

This paper presents a North–South model with differentiated goods being produced in the North. Each differentiated final good requires both management and manufacturing services as inputs, and firms are heterogeneous with regard to their productivity levels in providing these inputs. Two scenarios of relocating manufacturing to the South, which are interpreted to correspond to vertical foreign direct investment (FDI) and offshoring, are investigated. In both cases there is a minimum level of management productivity required for firms to benefit from relocation of manufacturing to the South. In the case of offshoring, productivity and profit gains are relatively larger for firms with low initial manufacturing productivity. Firms with high initial productivity in both aspects choose not to offshore owing to the presence of fixed costs. The model is subsequently used to examine the implications of global economic integration on the type of firm that exits an industry, changes production location or keeps manufacturing domestically.     

Total factor productivity in the Lithuanian family farms after accession to the EU: application of the bias-corrected Malmquist indices

The non-parametric measures of efficiency and productivity do not enable to fathom the underlying technology changes in terms of input saving and consumption. However, the bias-corrected Malmquist productivity index offers a remedy to this shortcoming. This paper, thus, employed the bias-corrected Malmquist productivity index to measurement of the total factor productivity changes in the Lithuanian family farms. The paper employed the Malmquist productivity indices to measure the technical changes (TCs) in terms of input-saving or input-use. Specifically, a sample of 200 family farms was used for the analysis. The research period covered years 2004–2009. The three farming types were considered, namely crop, livestock, and mixed farming. The analysis indicted that crop farming was peculiar with land-using and asset-saving TC, whereas labour-using and intermediate consumption saving TCs were observed only for certain combinations of inputs. As for livestock farms these generally experienced intermediate consumption and asset saving TCs against all the remaining inputs, whereas labour-saving and land-using TC varied with the reference inputs. Finally, mixed farms can be considered as those peculiar with increasing land use and decreasing capital consumption. Labour-using and intermediate consumption saving TCs did also hold for most of the analysed factors. The Lithuanian agricultural sector has not been analysed by the means of the bias-corrected Malmquist indices. Furthermore, there is a gap in the literature on the efficiency and total factor productivity in the Lithuanian farms in general. The present study, therefore, presents insights on the technology change based on non-parametric estimates.     

The Impact of Input and Output Tariffs on Firms' Productivity: Theory and Evidence

This paper studies the impact of trade liberalization on productivity. It shows that when intermediate inputs are not highly differentiated, lowering input tariffs leads to a rise in within‐firm productivity and wages, and lowering output tariffs has the opposite effect. When intermediate inputs are highly differentiated, the conclusions reverse. These predictions are supported by the data, given by the industrial survey from INEGI (Mexico's Insitituto Nacional de Estadistica Geografia e Informacion) in the period 1984–90. The paper yields estimates for the elasticity of substitution among intermediate inputs, which are useful in determining the direction of the impact of trade liberalization. These estimates can be used to assess the gains from trade liberalization.     

INDEX NUMBERS AND THE COMPUTATION OF FACTOR PRODUCTIVITY1

For purposes of analyzing the nature and meaning of index number formulas to be used in the calculation of factor productivity, a distinction is made between interetemporal comparison of factor productivity for a single country and contemporaneous comparison of factor productivity in two different countries. In the former case, the country in question is supposed ideally to be realizing fully its production possibilities, and the concern is seen as appraisal of shifts in such possibilities over time due to the advance of technological knowledge. Following Moorsteen such an advance is taken to be represented by the change in capacity to produce a standard mix of outputs per unit of a standard mix of inputs. Any mix might be standard, but those actually realized at the times in question are of particular interest. The index number formulas to be applied then depend on the assumed shape of the functions representing production possibilities. The conventional practice of aggregating output arithmetically and inputs geometrically, for example, is in order where production possibilities are given by an elaborated Cobb-Douglas function, but achieves only more or less approximate results otherwise. The analysis necessarily bears also on the prices at which inputs and outputs are to be valued. For the case of contemporaneous comparison of different countries, technological knowledge is taken ideally to be the same in the countries considered. Hence the concern is to gauge differences in production efficiency, i.e., realization of production possibilities. With production capacity understood to reflect any shortfall from possibilities, and hence production inefficiency in that sense, the analysis proceeds much as before, but given the fact of inefficiency determination of suitable prices for valuation of inputs and outputs becomes relatively difficult. Alternative expedients, none entirely satisfactory, are explored.
