China’s Capital Stock Series by Region and Sector

The lack of capital stock statistics for empirical research of the Chinese economy has for a long time been one of the major impediments in the profession. Professor Gregory Chow is one of the pioneers who attempted to deal with this matter. His seminal paper on China’s capital formation and economic growth was published in 1993 (Chow, 1993). Since then many authors have estimated their own capital stock data series. However, most authors have focused on investigations at the national level and their findings are not without controversies. In particular, few studies have provided estimates of capital stock for China’s regional economies. This paper adds to the existing literature in several ways. First, it presents a critical review of the methods and findings in the existing literature. Second, it proposes an alternative approach to estimate China’s capital stock series by region as well as across three economic sectors (agriculture, industry and services). Finally, preliminary analyses of the derived capital stock statistics are conducted to examine growth, disparity and convergence in China’s regional economies.     

THE RELATIONSHIP BETWEEN CAPITAL STOCK, UNEMPLOYMENT AND WAGES IN NINE EMU COUNTRIES

The focus of this paper is to investigate the importance of the capital stock in the determination of wages and unemployment in a range of EMU countries and to compare the results across countries. A time‐series analysis is conducted in the case of nine euro area countries, which were selected solely on the basis of data availability and consistency: Austria, Belgium, Finland, France, Germany, Italy, Ireland, the Netherlands and Spain. The paper begins with a short review of the literature on capital stock and unemployment, before it deals with the theoretical model. This is followed by estimation and testing of the theoretical model put forward, using both time‐series and panel data. The results are supportive of the main hypothesis of the paper: capital stock is an important determinant of unemployment and wages in the countries considered for the purposes of the paper.     

A Short‐Cut Method of Estimating Capital Stocks: When Can It be Used and How Well Does It Work?

Relatively few countries currently publish estimates of capital stocks because of the difficulty of applying the Perpetual Inventory Method. A short‐cut method which we term the Steady Growth Model (SGM) can produce plausible capital stock estimates provided certain conditions are met. Starting with a database covering 146 countries we conclude that the SGM can legitimately be used to calculate capital stocks for 53 of them. The 53 include equal numbers of high‐income and low‐income countries. The SGM requires only data on gross fixed capital formation for the base year, information about past growth rates of real GFCF, and assumptions about rates of depreciation. Despite its apparent simplicity, we show that our SGM stock estimates compare well with official stock estimates generated by the PIM. Other tests on capital–output ratios and capital‐stocks per head confirm the plausibility of stock estimates generated by SGM.

Is Public Capital Productive in China? Evidence from a Panel of Chinese Provinces

In addition to the direct productivity effect, public capital also has an indirect effect on private capital stock and labor input. This paper offers an evaluation of both the direct and indirect effects of Chinese public capital by applying a trans-log aggregate production function including public capital stock to a panel of regional data from 1986–2009. Moreover, we calculate the impact of public capital on regional total factor productivity (TFP) performance by introducing a system GMM estimation. The results show that the output elasticity of Chinese public capital stock is significantly positive, but decreasing year on year, and public capital is found to be a substitute for labor but complementary to private capital input. Finally, public capital has a significant positive effect on regional TFP performance.     

An estimate of the capital stock for the Belgian industrial sector

The paper submitted for publication considers the conditions for and the construction of a capital stock series, consistent with all macroeconomic relations. A careful study of the literature has shown that most existing and widely used capital stock series do not meet that requirement. A generative method with a general model for the real sector is proposed. The choice of the parameters of this model was decided upon the general consistency with the main macroeconomic aggregates. The results are compared with existing series of capital stock. What was obtained was a capital stock series that gives non-diverging results for the macroeconomic series when using the capital stock in alternative specifications. The main conclusions on depreciation rate, capital stock, technological change, return on capital and share of capital are condensed in a set of tables and diagrams.     

Depreciated Depreciation Methods? Alternatives to Sraffa’s Take on Fixed Capital

This article discusses the treatment of fixed capital in the classical theory of price. Sraffa uses non-linear depreciation of ‘physical’ capital that equalizes all annual profit rates individually, but violates the proportionality of monetary machine value reduction and physical use-up on an annual basis. One alternative is to apply simple linear depreciation that has equal annual fixed capital costs. The key for consistency is that the internal rate of return on fixed capital investments throughout the fixed asset lifetime must be equated with the normal profit rate. A second alternative is to use ‘monetary’ capital, where the ‘correct’ amortization charges depend on the ability of the accumulated depreciation fund to earn interest. Among these valid alternative methods are the original proposals of Marx and Torrens, which were dismissed falsely and prematurely by Neo-Ricardian economists. These alternatives are shown here to imply fundamentally different prices of production. For all methods, the formulas for deriving amortization charges and fixed capital prices of all vintages are derived. The article also illustrates how the system of Sraffian price equations can be modified to incorporate these methods.     

Brand capital and firm value

We study the role of brand capital – a primary form of intangible capital – for firm valuation and risk in the cross section of publicly traded firms. Using an empirical measure of brand capital stock constructed from advertising expenditures accounting data, we show that: (i) firms with low brand capital investment rates have higher average stock returns than firms with high brand capital investment rates, a difference of 5.2% per annum; (ii) more brand capital intensive firms have higher average stock returns than less brand capital intensive firms, a difference of 5.1% per annum; and (iii) investment in both brand capital and physical capital is volatile and procyclical. A neoclassical investment-based model in which brand capital is a factor of production subject to adjustment costs matches the data well. The model also provides a novel explanation for the empirical links between advertising expenditures and stock returns around seasoned equity offerings (SEO) documented in previous studies.     

HUMAN CAPITAL IN CHINA, 1985–2008

We estimated China's human capital stock from 1985 to 2008 based on the Jorgenson–Fraumeni (J–F) lifetime income framework. In order to accommodate the Chinese data and to capture human capital accumulation through both formal education and informal training, we modified the original J–F method by incorporating the Mincer model. We calculated total and per capita human capital stock for different population groups, and studied their trends and dynamics during the course of economic transition. We also constructed Divisia indexes of various orders to evaluate the contribution of different factors to the growth of human capital in China.     

What output-capital ratio to adopt for macroeconomic calibrations?

Regarding the output-capital ratio in heterodox macroeconomic simulation studies, a surprisingly wide range of numerical values can be found. The paper discusses quarterly US data that are publicly available where, in order to capture depreciation, the construction of the capital stock by the perpetual inventory method relies on detailed estimates of its lifetime. Subsequently the paper builds up a capital stock series by alternatively having recourse to the statistics about capital consumption and furthermore determining an initial level by an assumption about the long-term growth of capital. This procedure leads to somewhat different results. In addition, the rates of depreciation and profit are studied that are implied by the two approaches. The paper closes with two numerical proposals for the steady state values of these variables and the output-capital ratio that could be readily employed for macrodynamic modelling, and that are quite different from many of the aforementioned examples.     

Empirical evidence regarding electricity consumption and urban economic growth

Links between electricity consumption and economic growth are fairly well documented for national economies, but less so for urban economies. The analysis of such relationships at the sub-national level of aggregation can potentially offer a useful complement to national-level research. This study examines the electricity-growth nexus in El Paso, Texas, while also considering the roles of capital stocks and employment. Testing suggests the presence of cointegrating relationships and a vector error correction model is estimated. Granger causality tests reveal the absence of causality between electricity consumption and personal income, implying that energy conservation efforts will have a neutral effect on economic growth. Furthermore, the results indicate that causality runs from the capital stock and employment to both personal income and electricity consumption. This echoes previous research regarding the importance of accounting for capital and labour factors of production in studies of aggregate electricity utilization and economic performance. The methodology used in this analysis to develop a broad synthetic measure of the urban capital stock, including various categories of public infrastructure, can also be applied to other regions and urban economies.     

Realized volatility models and alternative Value-at-Risk prediction strategies

We assess the Value-at-Risk (VaR) forecasting performance of recently proposed realized volatility (RV) models combined with alternative parametric and semi-parametric quantile estimation methods. A benchmark inter-daily GJR-GARCH model is also employed. Based on four asset classes, i.e. equity, FOREX, fixed income and commodity, and a turbulent six year out-of-sample period (2007–2013), we find that statistical accuracy and regulatory compliance is essentially improved when we use quantile methods which account for the fat tails and the asymmetry of the innovations distribution. In particular, empirical analysis gives evidence in favor of the skewed student distribution and the Extreme Value Theory (EVT) method. Nonetheless, efficiency of VaR estimates, as defined by the minimization of Basel II capital requirements and its opportunity costs, is reassured only with the use of realized volatility models. Overall, empirical evidence support the use of an asymmetric HAR realized volatility model coupled with the EVT method since it produces statistically accurate VaR forecasts which comply with Basel II accuracy mandates and allows for more efficient capital allocations.     

Exhaustible resources,technology choice and industrialization of developing countries

How should the world economy adapt to the increased demand for exhaustible resources from countries like China and India? To address that issue, this paper presents a dynamic model of the world economy with two technologies for production; a resource technology, which uses an exhaustible resource as an input and an alternative technology, which does not. I find that both the time path of resource extraction and the adoption of the alternative technology depend on the optimal allocation of capital across the technologies, and on the size of the capital stock in relation to the resource stock. In particular, if the capital stock is low, only the resource technology is used initially and the alternative technology is adopted with a delay. Next, I use the model to analyze the effects of industrialization of developing countries on the extraction of oil and technology choice for energy production. As a result of industrialization, the alternative technology for energy production is adopted earlier.

That elusive elasticity and the ubiquitous bias: Is panel data a panacea?

There is often assumed to be a unit elasticity of substitution between capital and labour. But estimates based on neoclassical capital demand equations frequently find a smaller value. Recent time-series work for the United States and Canada has suggested that, once the biases inherent in estimating cointegrating vectors are properly accounted for, the elasticity could indeed be close to 1. We investigate this possibility for the United Kingdom. First we use aggregate data and find that the estimated elasticity is in the neighbourhood of 0.4. We then exploit a unique industry-level dataset for the United Kingdom to try and further pinpoint our estimates. Estimates using dynamic panel data methods are close to our benchmark estimate using aggregate data, providing a robust statistical rejection of a unit elasticity in UK data.     

PRODUCTIVE CAPITAL IN ITALY: A DISAGGREGATED ESTIMATE BY SECTORS OF ORIGIN AND DESTINATION: 1985–88

This study presents a series of matrices of the capital stock disaggregated both by branch of origin and by branch of destination for the years 1985 to 1988 for Italy. The tables, whose dimensions are 23 × 23, were constructed using the perpetual inventory method and are based on disaggregated time series of gross capital formation provided by Istat (Italian Statistical Institute). The tables refer to both gross and net capital (with straight-line depreciation) and have been tested on alternative hypotheses for the average expected service lives of capital goods and their survival functions.     

Efficiency‐adjusted public capital,capital grants,and growth

A debate on whether capital grants, and especially European Union (EU) funds, actually contribute to growth has gained prominence lately. This article empirically assesses the relationship between the quality of public investment, capital grants, and growth in a sample of 43 emerging and peripheral economies over 1991–2015. To this end, the contribution of public capital to growth is estimated using efficiency‐adjusted public capital stock series, which reflects the quality of public investment management institutions. In addition, the determinants of effective public investment are analyzed. The results suggest that capital grants contribute positively to effective public investment, and the latter is significant in explaining variations in economic growth. Finally, the article illustrates the impact of raising EU funds absorption on potential growth in emerging and peripheral EU countries.
