Computer Price Indices and International Growth and Productivity Comparisons

Methodologies to derive price indices for information and communication technology (ICT) products vary between national statistical offices. This may lead to significant differences in measured price changes for these products and there has been concern about the international comparability of volume growth rates of GDP between several OECD countries. This article discusses the possible consequences for measures of economic growth of replacing one set of price indices by another one in the framework of national accounts. It is argued that the issue of ICT deflators cannot be dealt with in isolation and several other factors have to be taken into account, in particular whether ICT products are final or intermediate products, whether they are imported or domestically produced and whether national accounts are set up with fixed or chain weighted index numbers. Overall, results point to modest effects at the aggregate GDP level but may be more significant when it comes to component measures such as volume growth of investment, or of output in a particular industry.     

AN ANNUAL CHAIN INDEX OF ITALY'S "REAL" PRODUCT, 1861–1989

The construction and application of a Paasche annual chain index to the Italian GDP figures between 1861 and 1989 is the subject of this article. Comparison with product at constant prices shows, except for war periods, a revaluation of GDP in favour of the annual chain index of around 0.10 percent. The most striking differences are concentrated into periods of marked changes in relative prices, and the new index modifies the temporal pattern of the growth trend by accentuating, without altering the periodization, cyclical fluctuations.     

FURTHER ANALYSIS OF THE TWIN DEFICITS

In a 1989 Contemporary Policy Issues article Miller and Russek published findings of a causal relation between the fiscal deficit and the trade deficit. However, they found no overwhelming support for reverse causation between the twin deficits. The authors of the analysis here gathered annual data on U.S. federal budget deficits and net exports for 1950–1988 and deflated the nominal values by the GDP deflators to examine the causal relation based on real values. They made a distinction between structural and actual budget deficits. Instead of an arbitrary choice of lag structure, they used Hsiao (1979, 1981) minimum final prediction error criterion to determine the optimum lag lengths of the explanatory variables. The analysis reveals a unidirectional causal relation running from structural budget deficits to net exports, confirming some of Miller and Russek's findings. Contrary to Miller and Russek's conclusions, however, findings here indicate a bi-directional causal relation between actual budget deficits and net exports. These findings suggest important policy implications.     

PRICES AND PRICE ANALYSIS IN THE FRAMEWORK OF THE NATIONAL ACCOUNTS

The paper discusses the role of prices in the framework of the new System of National Accounts (SNA) in terms of three major uses: (1) deflation, (2) price indicators, and (3) price analysis. Following a brief review of the price and quantity measures required by the new SNA with its emphasis on deflation of commodity flows and input-output accounts, in addition to the more conventional deflation of final demand categories, the paper discusses some of the conceptual, methodological and data problems involved in implementing the various uses of prices in the new SNA. Implementing the use of prices as deflators depends, in part, on the concept of output selected (national versus domestic; gross versus net), and which of six concepts of valuation, ranging from purchasers'value to true factor cost, is used. Some of the difficulties in deflating nonmarket flows (e.g., interplant transfers) and industry value added, based on the double deflation method, are discussed. In concept price deflators, which have shifting weights, cannot be used as price indicators, which should have fixed weights. In practice, this is often disregarded and the deflators are used as price indicators. The paper support the SNA recommendation for the development of price indexes with fixed weights to be used as price indicators, in addition to the implicit price deflators. Research in the United States indicates that differences in weights can result in different price measures for various subperiods, components of demand and sector output. Periodic revisions in weights to provide more current fixed weights for price and quantity indexes in each subperiod may minimize the problem but it introduces a new problem—lack of comparability with the constant price tables in the SNA which have fixed weights for the entire period. The new SNA provides a comprehensive and integrated framework for price analysis including the analysis of the structure of aggregate price changes, the industrial origin of final demand prices, and the impact of price change in one sector of the economy on the rest of the economy. Some major gaps which need to be overcome in order to implement the use of the new SNA for price analysis include the development of industry capital stock estimates, separate estimates of proprietors’income, reconciliation of value added and distribution share estimates, and the development of a wide variety of information to supplement the conventional input-output tables in the SNA. Implementing the various objectives of price measures within the framework of the accounts will require a number of improvements in existing price measures and expanding the scope of coverage. “List” prices should be superseded by “transactions” prices and better techniques and data need to be developed to provide for quality adjustment of prices. Coverage will need to be expanded to include services, freight rates, trade margins, government expenditures, and also fill in gaps for many manufactured products. Finally, where possible, use of unit values as price indexes or deflators, e.g., imports and exports, should be replaced by direct price measures.     

NEW ESTIMATES OF THE U.S. ECONOMY'S POTENTIAL GROWTH RATE

Using an Okun's law framework, the analysis here estimates potential growth for the 1990s as measured by both fixed- and chain-weighted GDP. It then decomposes estimated potential growth rates into labor productivity growth (LPG) and labor input growth (LIG) using a regression analysis to separate secular from cyclical changes. It compares estimates of potential output and trend productivity growth for the 1990s with estimates from earlier periods. Results indicate that eliminating the substitution bias associated with fixed-weight measures of real GDP raises estimated potential GDP growth in the 1980s but lowers it in the 1990s. A slowdown in labor force growth, with little or no change in long-term productivity growth, largely accounts for the implied slowdown in potential growth.     

How productivity and domestic output are related to exports and foreign output in the case of Sweden

In this paper we examine the relationships between two sets of three variables: Swedish real exports, Swedish real GDP, and foreign real GDP in one set; and Swedish real exports, Swedish total factor productivity, and foreign real GDP in the other set. The foreign real GDP facing Sweden is proxied by total OECD real GDP minus Sweden's real GDP. Multivariate tests for integration and cointegration show that the variables in each model are cointegrated. We also perform Granger causality tests on these variables in our examination using the Toda-Yamamoto procedure. We discover bi-directional causality between Swedish real exports and Swedish real GDP (or Swedish total factor productivity). Foreign real GDP is shown to Granger cause Swedish real exports, but no significant causation of foreign real GDP on either domestic GDP or total factor productivity was found. A change in foreign real GDP thus appears to affect Swedish output and productivity only indirectly, through changes in Swedish exports. JEL classification:F41, F43, C30, C32     

MEASURING OUTPUT FROM THE PUBLIC SECTOR: A CRITICAL EXAMINATION OF THE ATKINSON REVIEW

In 1993 a new page was turned in national accounting. The United Nations Standards of National Accounting recommended a new standard for the measurement of output from the public sector. Implementation has recently begun in many countries, in Europe based on a European Union directive. In the U.K. the Atkinson Review in 2005 came up with a series of recommendations. This article examines its recommendations concerning the definition and valuation of government outputs. For the non‐market sector a market analog is recommended by the Review. However, several of its recommendations are inconsistent with that, championing social value as a basis for definitions and measurement. If taken seriously it will lead to arbitrary and politically controversial factors inserted into national accounts. The article highlights the norm that GDP is a measure of production, and advocates adhering to the market analog and following well recognized practices of national accounting.     

EFFECT OF GROUPING OF DATA ON THE DIVERGENCE BETWEEN LASPEYRES AND PAASCHE FORMS OF QUANTUM INDEXES*

Historical data for the manufacturing industry in the United States and United Kingdom are quoted, showing in most cases divergences between Laspeyres and Paasche forms of the quantum index that are by no means negligible. When the Paasche index for two of the series is recalculated with quantity indicators for industries instead of for products, the divergence is greatly reduced, and when quantity indicators for industry groups are substituted it almost disappears. This raises some questions about the practices of econometricians and statisticians, which are discussed. In a mathematical appendix by E. R. Coleman it is suggested that the grouping effect referred to does not depend on the particular way in which the data are grouped in most quantum indexes.     

The economic contribution of the “C” in ICT: Evidence from OECD countries

Numerous studies have documented the contribution of ICT to growth. Less has been done on the contribution of communications technology, the “C” in ICT. We construct an international dataset of fourteen OECD countries and present contributions to growth for each ICT asset (IT hardware, CT equipment and software) using alternative ICT deflators. Using each country’s deflator we find that the contribution of CT capital deepening to productivity growth is lower in the EU than the US. Thus we ask: is that lower contribution due to a lower rate of CT investment or differing sources and methods for measurement of price change? We find that: (a) there are still considerable disparities in measures of ICT price change across countries; (b) in terms of growth-accounting, price harmonisation has a greater impact on the measured contributions of IT hardware and software in the EU relative to the US, than that of CT equipment; over 1996–2013, harmonising investment prices explains just 15% of the gap in the EU CT contribution relative to the US, compared to 25% for IT hardware; (c) over 1996–2013, CT capital deepening accounted for 0.11% pa (6% as a share) of labour productivity growth (LPG) in the US, compared to 0.03% pa (2.5% of LPG) in the EU-13 when using national accounts deflators; and (d) using OECD harmonised deflators, the figure for the EU-13 is raised to 0.04% pa (4% of LPG).     

ON THE TREATMENT OF TAXES AND GOVERNMENT IN THE NATIONAL ACCOUNTS

Framed in the context of the ongoing revision of the 1993 System of National Accounts (SNA), this note proposes a new presentation of the National Accounts. While it does not require new information, nor difficult calculations, it is suggested to be conceptually clearer and practically simpler. The changes concern the treatment of taxes and government in the national accounts which imply that: (i) GDP, measured at basic price, is now exactly the sum of all value added, which is split in the compensation of employees and an enlarged operating surplus; (ii) the two functions of government are clearly distinguished in a modified sequence of accounts, that is, as producing non-market services up to the allocation of primary income account, and then as redistributing the national income; and (iii) with a conventional allocation of government services and GDP broken down between market GDP and non-market GDP, households remain the only final consumer and the so called question of consumption subsidies is resolved.     

THE USA AS THE 'DEMANDER OF LAST RESORT' AND THE IMPLICATIONS FOR CHINA'S CURRENT ACCOUNT

Abstract.  The present paper evaluates the current account patterns of 69 countries during 1981–2006. We identify an asymmetric effect of the USA as the 'demander of last resort': a 1% increase in the lagged US imports/GDP is associated with a 0.3% increase in current account surpluses of countries running surpluses, but results in insignificant changes in the current accounts of countries running deficits. The impact of US demand variables is larger on the current accounts of developing countries than that of OECD countries. We also contemplate China's current account over the next 6 years, and project a large drop in its current account/GDP surpluses.     

THE DEVELOPMENT OF THE DISTRIBUTION OF WEALTH IN SWEDEN

This paper is concerned with the distribution of wealth in Sweden in 1975 and its development during the period 1920–75. The paper is based on a large study on wealth undertaken for the Swedish Commission on Wage-Earners and Capital Formation. The first report from this study was presented in 1979 as a book in Swedish: Roland Spånt, Den svenska förmögenhetsfördelningens utveckling (The Development of the Distribution of Wealth in Sweden), SOU 1979:9. That first report will also be published in English. Prior to that the main results can be found in this paper.
During 1980–81 we intend to publish specific reports on the distribution of shareholding, the effects of inflation, the development of the distribution of wealth 1975–78, the importance of pension rights etc.     

Wood and industrialization: Evidence and hypotheses from the case of Spain, 1860-1935

The aim of this paper is to study wood consumption during the industrial expansion which took place in the western world in the second half of the nineteenth and the first decades of the twentieth century, through the analysis of the case of Spain. For this purpose, we present the series of Spanish wood consumption both as a raw material (WRM) and as firewood (FW) between 1860 and 1935 and we carry out two exercises with these series. The first calculates the intensity of use (IOU), which relates wood consumption in physical terms with the evolution of the GDP. The second, more complex, exercise estimates a standard consumption function that allows us to know the elasticity of WRM with respect to the GDP, the Spanish price of wood and the Spanish price of a substitute material like iron. Based on our results, we discuss the lower dependence of the Spanish industrial economy on wood, the “liberation” of forest areas that may have occurred in Spain as a result of industrialization, and to what extent the trends observed for the Spanish case can be extrapolated internationally. The main conclusion is that industrialization transformed the uses of wood and, though the importance of this resource per unit of GDP decreased, its overall consumption increased, generating greater pressure on forests at an international level.     

Tariffs and economic growth in the first era of globalization

Are liberal trade policies good for growth? Sceptics often point to the late nineteenth century as a period when protectionist policies promoted economic development. This apparent blueprint for the benefits of protectionism paradoxically comes from a period that is often described as the first era of globalization. In this paper we reassess the empirical evidence about the relationship between tariffs and growth between 1870 and 1914. Our key findings challenge the idea that in the nineteenth century countries that raised tariffs thereby increased their own growth rate. Using new and improved data and employing a whole portfolio of econometric tests we do not find evidence that increased protectionism raised the rate of individual countries’ growth. While some positive cross-sectional correlation exists between tariffs and growth, this may reflect unobserved country traits rather than a causal relation. There is equally little evidence that other external factors, such as real exchange rates and terms of trade changes, were key drivers of economic performance. A paradox of this first era of globalization is not that free trade was bad for growth; it is that international economic policies seem to have mattered little to countries’ growth trajectories.     

SERVICE PRODUCTION IN HISTORICAL NATIONAL ACCOUNTS

Constant price calculation of service production is a problematic issue in contemporary national accounts, and it is far more so in historical series. The indicator method has been suggested as one way of coming to terms with volume calculations. This method is scrutinized, and it is claimed that it does not represent the solution for historical matters. Instead, various techniques have to be used for various parts of the total. The methods of deflating service production in five countries' historical national accounts as well as the consequences of using different methods are compared. Most often, existing series are not compatible with those for goods production, which of course has repercussions on attempts to study e.g. productivity. It is concluded that much work has to be done to improve the methodology and to arrive at a common international framework for historical national accounts.     

THE "REAL" CHINESE GROSS DOMESTIC PRODUCT (GDP) FOR THE PRE-REFORM PERIOD 1952–77

This paper develops an econometric method based on the relationship between GDP and NMP to estimate an unknown Chinese GDP series of 1952–77 using recently available Chinese GDP data of 1978–90 and a reconstructed NMP series of 1952–90. In this manner, a long-term (1952–90) series of China's GDP has been obtained for long-term analyses. A reassessment of Chinese economic performance of 1952–90 using this series suggests that the paper's estimate provides a reasonable reflection of both the Chinese pre-and post-reform economic growth in terms of production structure, growth pattern and policy changes. A series of China's per capita GDP in U.S. dollars which is comparable to the World Bank's estimate for the early 1980s has also been obtained.     

On the relevance of exports for regional output growth in China

Despite high economic growth during the past decades, China is still vulnerable to shocks arising from industrial states. The advanced economies strongly influence Chinese export performance, with subsequent effects on output growth. Using a production function, this article examines to which extent regional GDP growth in China is export driven. In a panel of 28 Chinese provinces, series are splitted into common and idiosyncratic components, the latter being stationary. The results indicate cointegration between the common components of GDP, the capital stock and exports. In equilibrium, exports increase GDP by more than their impact expected from the national accounts. While exports and capital are weakly exogenous, GDP responds to deviations from the long run. A similar adjustment pattern can be detected for most regions, except for some provinces in the Western part of the country.     

TERMS OF TRADE AND ECONOMIC GROWTH IN NINETEENTH CENTURY BRITAIN *

International trade and economic growth have been considered intimately linked in nineteenth century Britain. Conventional estimates of Britain's gross national product, however, fail to account for changes in the terms of trade and may be misleading indicators of changes in real income. Revised figures that incorporate terms of trade changes are presented here. One finding is that conventional estimates of GNP overstate growth in real income early in the century when the terms of trade deteriorated.     

CAN INVESTMENT IN INTANGIBLES EXPLAIN THE SWEDISH PRODUCTIVITY BOOM IN THE 1990s?

In the early 1990s the Swedish economy experienced a severe economic and financial crisis which resulted in a substantial GDP decrease. Even though the crisis was not a complete surprise for many economists, almost no one expected that the Swedish economy would be prospering with booming productivity growth only a few years later. Economists have presented three explanations for the fast recovery and productivity growth in 1995–2006: market reforms, crisis recovery, and the impact of ICT. This paper offers an alternative view, emphasizing instead firms' substantial investment in intangible assets such as R&D, design, and advertising. Based on the growth accounting framework, intangible capital accounted for more than 30 percent of the labor productivity growth in the Swedish business sector from 1995 to 2006. Thus, Swedish TFP growth, one of the highest among OECD countries, is reduced substantially when investment in intangibles is included in the growth accounting analysis.     

THE EXPORT PERFORMANCE OF U.S. AND SWEDISH MULTINATIONALS

While the U.S. and Sweden both lost more than 20 percent of their shares of world and developed countries' exports of manufactures between the mid-1960s and mid-1980s, the export shares of their multinational firms stayed fairly stable or even increased. The multinationals raised the proportion of their worldwide exports that they supplied from their overseas affiliates. These developments suggest that the declines in the trade shares of the US. and Sweden were not due mainly to deterioration in the innovativeness or inventiveness of American and Swedish firms, their management ability or their technological capabilities, but rather to economic developments in the firms' home countries.
The finding that firms have done better as exporters than their home countries is strengthened when we look at different industry groups. In both the U.S. and Sweden, and in all industry groups, with one exception, the multinationals' export shares increased relative to those of their home countries. The margins were often wide, and were mostly larger for Swedish firms than for U.S. firms.
Part of the explanation for the growth of each country's exports and those of its multinationals is the initial composition of exports, or the comparative advantages of the countries and their firms. These were skewed, in the mid-1960s, to industries that were to enjoy rapid growth in the next decade or so. Despite these initial comparative advantages, the exports of both countries fell far behind world export growth.
The comparative advantages of both countries' multinationals were even more biased toward fast-growth industries than those of the countries. That fact partly accounted for the better export performance of the multinationals relative to their home countries, but the multinationals outperformed their countries within each industry as well as for manufacturing as a whole.
