ESTIMATES OF THE AGGREGATE QUARTERLY CAPITAL STOCK FOR THE POST-WAR U.S. ECONOMY

We construct quarterly aggregate gross and net capital stock series for the post-war U.S. economy using annual capital stock, capital depreciation, and capital discard figures along with quarterly investment series. We construct nominal and real measures of all three categories in the aggregate capital stock: consumer durable goods, producer durable goods, and business structures. In constructing the nominal series we take into account the changes in capital goods' prices. The series are constructed using four different methods. Using time- and frequency-domain techniques, we compare the constructed series and characterize their short-run, business cycle, and long-run cyclical properties. We find that the constructed series exhibit very different cyclical and shock persistence dynamics. Practial implications are discussed.     

ESTIMATES OF CAPITAL STOCK BY INDUSTRIES IN THE FEDERAL REPUBLIC OF GERMANY

The main purpose of this paper is to discuss some of the measurement problems in connection with the perpetual inventory method applied for estimates of capital stock. In the Federal Republic of Germany, highly aggregated capital stock data by business sector are compiled by the Federal Statistical Office within its national accounts calculations, while more detailed capital stock estimates by industrial sectors are published by the German Institute of Economic Research (DIW) in Berlin. Because of various gaps in the statistical sources, the accuracy of the capital stock calculations is not yet entirely satisfactory. Aside from the problem of establishing long time series for gross fixed capital formation in constant prices for all sectors, it is difficult to obtain reliable data on the inter-sectoral transactions in secondhand capital goods. In addition, there are problems of determining price indices and service life distributions of the fixed assets in the various parts of the economy. This paper shows a way to arrive at a reasonably close approximation to the latter problem.     

APPRAISING THE U.S. OUTPUT AND PRODUCTIVITY ESTIMATES FOR GOVERNMENT–WHERE DO WE GO FROM HERE?

Output and productivity estimates for U.S. government organizations are a useful management tool, and are of potential value for improving national income accounts. Real gross government product is currently estimated on the basis of labor input data. However, this imparts a downward bias to real GNP estimates since labor productivity of federal civilian employees has risen, according to Labor Department estimates begun in 1972, at an average annual rate of 1; percent since 1967. The estimates now cover almost 70 percent of the employees. The chief avenue for further improvement lies in refinement of the output indicators. Coverage of state and local government employees is spotty and needs to be expanded. The author also recommends a major effort to estimate public capital stocks in current and constant prices as a basis for measuring rental values, capital inputs, and productivity.     

A cost-based analysis of scale economies in the French auto industry

This paper examines cost relationships in the French automobile industry using a translog cost function with domestic capital and labor and domestic and foreign intermediate goods inputs. The findings suggest scale economies at lower output levels, but diseconomies at mean and maximum output levels. Cross price elasticity estimates implied all input pairs except capital and foreign parts and labor and domestic parts are substitutes. Except for foreign components, direct price elasticity estimates were inelastic. Thus, further integration of Europe and reduction of foreign input prices may substantially increase their quantity demanded and decrease the demand for domestic labor and parts.     

U.S. REAL PRODUCT AND REAL FACTOR INPUT, 1929–1967

The objective of this paper is to provide a conceptual basis for separating social product and social factor input accounts into price and quantity components. Despite the essential similarity between concepts of real product and real factor input, the measurement of social factor outlay in constant prices is not well established in social accounting practice.
Production accounts are constructed for the United States in current and constant prices, including social product and social factor outlay, for the period 1929–1967. The resulting estimates are applied to the measurement of total factor productivity and the study of the responsiveness of product and factor intensities to price changes.     

Factor analysis of demand growth for information technology input in Japan

The purpose of this article is to decompose demand changes for factor input and explore the factor that information technology (IT) capital stock has largely increased in Japan. The Allen partial elasticities of substitution are calculated and the variations in factor input demand are broken down into two effects—price effect and output effect, using industry-level data. From an estimation of the total cost function, the following conclusions are presented. While IT capital stock and ordinary capital stock are complementary, IT serves as a substitute for labor. The factors influencing the high growth rate in IT capital stock are the decrease in the prices of IT and ordinary capital services, and the increase in the labor price, in addition to the output effect. On the other hand, labor demand declines due to both the downward rigidity of wages and the decrease in prices of two kinds of capital services.     

生产性服务业细分行业技术进步率分析——以广州市为例

本文选取广州市1988—2007年服务业数据,运用面板模型对广州市生产性服务业细分行业的技术进步率进行测算和分析,研究结果表明:在其他要素投入保持不变的情况下,广州市生产性服务业资本存量1%的增长可以导致服务业增加值0.84%的增长;相应地,劳动投入1%的增长可以产生服务业增加值0.26%的增长。但是,服务业整体的技术进步贡献率仍然比较低,技术进步表现较佳的行业往往就是地方服务业的主导行业,如金融、国家机关和科技服务业,它们是广州吸引投资、保证产业繁荣的关键。而交通、批发零售、卫生和教育的技术进步水平有待提高。本文建议强化技术和利润之间的联系,建立有利于人才培养、知识产权保护和信息沟通的开放的环境。     

转轨时期我国行业层面资本积累的研究——资本存量和资本流量的测算

本文区分了资本财富存量估算和资本服务流量估算的差异,并使用OECD的资本测算框架估算了具有国际可比性的我国行业层面资本存量和资本流量数据。结果表明,同发达国家相比,不管是资本产出比还是资本收益率数据,都不能说明我国资本积累过度;但基础设施行业的资本积累速度明显偏快。从资本流量估算结果发现,制造业的资本生产率在提高,而第三产业特别是基础设施行业资本生产率在下降;第三产业的产出增长主要来自资本的贡献;而行业间资本再配置效应为负。     

Evidence that capital formation is overestimated in low- and middle-income countries in ICP 2011

Using the International Comparison Program (ICP) 2011’s cross-country data on input prices and project cost shares, I show that the ICP 2011 construction prices are substantially underestimated in the 143 low- and middle-income countries where these prices were estimated from input prices. As a consequence, the ICP 2011’s estimate of PPP-adjusted construction is overestimated on average by about 100% and gross fixed capital formation is overestimated by 25–30% in these countries. These nonrandom data errors are of sufficient magnitude to cause serious estimation bias in cross-country growth analyses.     

Estimates of China capital input index by industries (1981–2000)

The purpose of this paper is to report estimates of capital input index classified by industries in China from 1981 to 2000. We estimate capital stock based on the perpetual inventory method, and then estimate the flow of capital service and capital service price consistently with the capital compensation in input-output table. In our study, we discuss various assumptions and adjustments made on the data and estimation implementation.      

A Comparison of PIM Estimates with Direct Stock Information for Dwellings

One of the major sources of uncertainty in capital stock estimates stems from the use of the perpetual inventory method (PIM) in all the cases where direct stock information is not available. In the Danish capital stock estimates, it has been possible to dispense with the PIM as far as buildings are concerned. Instead, an administrative register of buildings is used together with a property register and the business register to produce an exhaustive enumeration of practically all buildings in the economy broken down by industry and sector. For the most important type of buildings, namely dwellings, the paper compares direct stock estimates derived by multiplying physical quantities (square meters) by the replacement prices per square meter with those that would result from applying the PIM to historical investment series. Dwellings are by far the most important non-financial assets in most developed economies.     

CHALLENGES FOR FRANCE IN THE EMERGING INTERNATIONAL ENVIRONMENT: A DYNAMIC ANALYSIS

France faces substantial challenges as the economic integration of Europe and the international economy continues. This article uses a dynamic aggregate translog cost function with inputs of capital, labor, and imports to examine the likely impact of closer world economic ties on France. This technique allows one to estimate short- as well as long-run direct price elasticities of demand for the inputs and cross-price elasticities for each respective input pair. The findings of the article include that (1) the French economy is becoming more sensitive to changes in import prices and (2) all the inputs are substitutes for one another. These results suggest that continuing international economic integration will present substantial challenges to the French economy. The short-run estimates of direct and cross-price elasticities are consistent with the Le Châtelier principle, except for the cross-price elasticities between capital and labor. Some possible reasons for the latter result are discussed in the article. (JEL F14, O10, O12)     

International Comparisons of Levels of Capital Input and Multi-Factor Productivity

Abstract. The paper uses a method by Christensen et al. to construct cross-country comparisons of the levels of capital input, capital and labour productivity and multi-factor productivity. These results are used to decompose international differences in gross domestic product per capita into differences in labour utilization, information and communication technology (ICT) and non-ICT capital intensity and multi-factor productivity for seven Organisation for Economic Co-operation and Development countries. We provide Monte Carlo estimates to examine the effects of measurement errors in the base data, and these simulations showed that boundaries for the resulting indicators can be important.     

Lindahl Pricing, Nonrival Infrastructure, and Endogenous Growth

The paper constructs a model of endogenous growth where infrastructure is an accumulable stock generating a nonrival input service. A typical market economy cannot attain the socially optimum steady state path, since nonrivalry precludes competitive pricing of infrastructure. However, there exist agent specific prices for the infrastructural service, a price for the infrastructural stock, a rate of interest, and a subsidy for the representative household that can sustain the optimal path as a dynamic Lindahl equilibrium. The rates of return from physical and infrastructural capital equal the rate of interest. Investment programs are socially optimum. The government's budget is balanced.     

Input cost, capacity utilization and substitution in the short run

This article studies the behavior of input cost shares in an environment where labor is costly to adjust, materials can be adjusted at no cost and capital is fixed. A model relating cost shares with relative prices and adjustment costs is proposed, allowing joint estimation of the elasticity of substitution and the adjustment cost function, which is an unknown function of the capacity utilization. Based on a panel of more than 700 manufacturing firms, we find evidence of strong input share variations according to the degree of capacity utilization. The estimated shapes of adjustment costs curves of labor are in agreement with our theoretical model, and we obtain sensible elasticities of substitution estimates. Based on such estimates, we find evidence of a negative (positive) bias in downturns (recoveries) in conventional productivity growth measures.     

CAN A PERPETUAL INVENTORY CAPITAL STOCK BE USED FOR PRODUCTION FUNCTION PARAMETER ESTIMATION?

Due to lack of data on capital disappearance, we simply do not know the covariance of the capital stock with factor inputs and prices well enough to estimate production function parameters. Since replacement rates are rational economic decisions, the errors in a perpetual inventory capital stock vary systematically with the business cycle and such economic variables as rates of technical progress and interest rates. This introduces systematic errors into calculated parameters of production functions and rates of technical progress.     

Biofuels and Land Use Change: Sugarcane and Soybean Acreage Response in Brazil

Scientists and economists are increasingly worried that biofuels production is leading to land use changes in the form of competition with food crops or loss of natural ecosystems. I estimate acreage conversion in response to shocks in sugarcane (a biofuels feedstock) and soybean (thought to be affected by United States corn ethanol production) prices in Brazil at a national and regional level. Using county-level data from 1973 to 2005, I consider a dynamic panel data model of input demand for agricultural land, conditioning on price changes of other commodities. The short-run crop-price elasticity of sugarcane acreage in Brazil is estimated to be approximately zero, whereas the elasticity of soybean acreage is 0.9 when both spot and futures prices change. The regional estimates for soybeans show considerable variation, and are highest in areas of ecological importance, such as the cerrado. Sugarcane estimates are more homogeneous. These results should be taken into account in impact assessments of biofuels.     

NEW ESTIMATES OF GROSS NATIONAL PRODUCT FOR THE UNITED KINGDOM 1830–1914

This paper presents a new annual series for United Kingdom gross national product, at current and constant prices, calculated from the expenditure side. These results differ significantly from previous estimates in that they go back to the beginning of the railway age on an annual basis and also in that the constant price estimates involve a detailed deflation of the main components of expenditure on consumption and capital formation. The implications of the new results are summarised, with particular reference to rates of growth and relative price changes, and an appendix describes the sources of the estimates.
