INTERNATIONAL COMPARISONS OF WEALTH INEQUALITY

This study presents reasonably comparable estimates of the size distribution of household or personal wealth for eight OECD countries—Australia, Canada, France, Germany, Japan, Sweden, the United Kingdom, and the United States. In the mid-1980s, the U.S. ranked as the most unequal and Japan the least, while the other six countries had roughly comparable levels of wealth inequality. Moreover, while wealth inequality rose sharply in the U.S. during the 1980s, it increased modestly in Sweden and showed little change or a slight decline in Canada, France, and the U.K. A comparison of time trends for the U.K. and the U.S. suggests that the relatively high wealth inequality in the U.S. in the 1980s represents a marked turnaround from the 1950s, when the U.S. was considerably more equal in terms of wealth ownership than the U.K. Comparative results for the two countries hold for both conventional (marketable) wealth and for augmented wealth, which includes a valuation of public and private pension wealth.     

INTERNATIONAL COMPARISONS OF AUSTRALIAN GDP IN THE 19TH CENTURY

This paper summarises the results of a new comparison of the level of Australian and U.K. real product in the 1890s, obtained by the direct deflation of money values of GDP by relative prices. The object of the study was to provide a check on the existing comparisons, obtained by extrapolation of time series of real GDP, as shown, for example, in Maddison (1982). Existing estimates imply that in the 1890s Australian GDP per capita was about 50 percent higher in the U.K. and U.S.A. and more than twice that for the average of 12 other western countries. The present study suggests these results probably overstate Australia's real GDP, and that Australian real GDP per capita was 36 percent higher than the U.K. in 1891 and 3 percent higher in 1900. Personal consumption per capita was 15 percent higher in Australia than in the U.K. in 1891, but about the same level in 1900.
Although this study compares prices and GDP in the colony of New South Wales with those in the U.K., the colony may be taken as representative of Australia as a whole.¹     

THE SENSITIVITY OF INTERNATIONAL POVERTY COMPARISONS

Using data from the Luxembourg Income Study, I study the sensitivity of cross-national income poverty comparisons to the method in which poverty is measured. Absolute poverty comparisons that keep the purchasing power at the poverty line constant across countries lead to conclusions that differ from relative poverty comparisons in which the real value of the poverty line varies with average income. The absolute poverty ranking of countries also varies as the real value of the poverty line is lowered. Cross-national differences in household characteristics are largely irrelevant in explaining poverty differences.     

INTERNATIONAL COMPARISONS OF INTER-INDUSTRY WAGE DIFFERENTIALS

We use OECD data to examine inter-industry wage differentials (relative wages among industries) for 14 OECD countries over the period 1970–85. We find, first, that the industrial wage structures have shown remarkable stability over time in terms of rank order for all the countries in the sample. Second, despite their rank order stability, wage structures show a tendency to expand or contract. While the U.S. has shown increasing industry wage dispersion between 1970 and 1985, the pattern is very mixed for other countries. Unionization is a significant factor in explaining cross-country differences. Third, industry wage rankings show some evidence of becoming increasingly similar across nations over time, and this movement is associated with a convergence of per capita incomes. Fourth, industry wage differentials are positively related to an industry's productivity growth, output growth, capital intensity, and export orientation.     

INTERNATIONAL COMPARISONS OF EARNINGS INEQUALITY FOR MEN IN THE 1980s

In this paper we present a comparative analysis of earnings inequality during the 1980s among prime age men who headed households and worked year-round, full-time from five industrialized countries-Canada, Sweden, Australia, West Germany, and the United States. The data were obtained from the Luxembourg Income Study (LIS) database, a multinational collection of microdata sets from various countries which have been assembled for the primary purpose of making cross-national comparisons of economic and social well-being. The results of the comparison indicated that during the mid-1980s, the United States had the most unequal distribution of earnings and Sweden the least unequal. Between the early 1980s and mid-1980s, however, the earnings distributions in all five countries showed evidence of becoming more unequal, especially in the United States, Canada, and Sweden.     

京津都市区制造业劳动生产率变化的分解分析

以北京和天津为主体的大都市区,不仅是华北地区的经济核心区,更承担着全国参与世界经济竞争的职能,其中制造业仍是区域竞争能力演变的重要驱动因子,因此,增强京津都市区制造业的发展水平是提升本区国际竞争力的重要内容。该研究旨在对京津地区制造业的劳动生产率变化进行结构解析,明晰该区制造业劳动生产率变化的结构来源,为打造新型产业分工提供决策参考。研究表明,自1997—2007年间,北京和天津制造业的总体劳动生产率水平显著高于全国,大约相当于全国的2倍;研究期内京津地区的制造业生产效率均有显著增长,且自2005年以后天津制造业总体劳动生产率高于北京。采用Laspeyres指数分解法对京津两地制造业劳动生产率变化的结构分解结果表明:纯生产率效应即行业劳动生产率的变化是导致制造业整体劳动生产率变化的主要源泉,由劳动力等要素的流动导致的行业结构调整即结构红利效应并不显著。对制造业劳动生产率行业分解结果表明:京津两地制造业劳动生产率的变化主要源于通信设备、计算机及其他电子设备制造业、交通运输设备制造业、黑色金属冶炼及压延加工业和化学原料及化学制品制造业等技术与规模经济指向型行业。结论主张京津地区制造业要尽快以新型产业分工为基础,根据城市自身优势,实现制造业产品和功能的差异化战略,共同打造全球重要的现代制造业基地。     

THE SUBSTITUTABILITY OF CAPITAL, LABOR, AND R&D IN US MANUFACTURING

This paper examines the relationship between inputs in industrial production. The inputs studied here are capital, labor, and research and development (R&D). Using translog technology, our cross-industry analysis of six industries reveals that capital and labor are complements in production while R&D and labor are substitutes. However, the relationship between capital and R&D is not so clear cut. It is also found that constant-returns-to-scale hold for only two of the six industries. A test of sensitivity to changes in the R&D depreciation rates suggests that some industries are sensitive to such changes.     

INTERNATIONAL AND INTERTEMPORAL COMPARISONS OF REAL PRODUCT IN OECD COUNTRIES A GROWTH SENSITIVITY ANALYSIS

This paper provides two new data sets for comparisons of real income in OECD countries. The first set provides adjusted real series for GDP and its components from 1960 to 1993 based on OECD 1990 purchasing power parities. The second set uses OECD PPP of different benchmark years, and interpolates these applying national price indices. Comparisons between both alternatives, Penn World Tahle Mark 5 (PWT 5) and its new version (PWT 5.6), in terms of economic growth and convergence, reveal some remarkable differences. Moreover, there are wider differences concerning the relative countries' position in GDP per capita ranking. Estimations of convergence equations based on OECD data yield a better fit than those obtained using PWT data, although there are also some significant differences between PWT 5 and PWT 5.6. Nevertheless, a very positive result is that other parameters of interest in these equations are not affected by the use of these different data sources.     

MEASURING HOUSEHOLD ACTIVITIES: SOME INTERNATIONAL COMPARISONS

This paper focusses on macroeconomic approaches to the measurement of non-market household work or production in industrialised countries. It details the variety of parameters involved, the choice of which depends on the specific aim pursued by authors. A review of different aims pursued, parameters chosen, concepts used, alternative methods applied, and available statistical data is presented and results of evaluations are then compared. The money value of household activities is given in percentage of GNP and comparisons are made within the framework of similar approaches. Under this condition, results are remarkably consistent. At the same time, the paper shows how sensitive results are to the method used; it also puts emphasis on the lack of adequate statistical data which may be held responsible for a gap between the theoretical model of evaluation and its practical implementation. In the present state of knowledge, no definite assertion can be made on the time trend of household work and its money value as percentage of GNP or national income. The paper stresses the importance availability of data on the volume and nature of non-market household output would have for future research on the economic contribution of households in industrialised as well as in developing countries. Such data permitting an output approach to measurement would lead to better understanding of the interrelation between market and household sectors and would therefore improve economic analysis and forecasting. Adequate statistical data could possibly be collected through a process similar to that used for time use data in national surveys.     

A TAXONOMY OF MULTILATERAL METHODS FOR MAKING INTERNATIONAL COMPARISONS OF PRICES AND QUANTITIES

A taxonomy of multilateral methods is developed. All the main methods are classified within the taxonomy. It is then shown that methods in the same class share many of the same properties. Therefore the taxonomy should help practitioners to appreciate the wide range of alternative methods for making international comparisons, the relationships between methods, and the relative strengths and weaknesses of each method.     

INCOME INEQUALITY IN AUSTRALIA AND NEW ZEALAND: INTERNATIONAL COMPARISONS AND RECENT TRENDS

In this paper we present results on the distribution of income in Australia and New Zealand that can be compared with those for a range of other advanced countries. The framework of analysis, concepts and definitions used have been developed as part of the Luxembourg Income Study (LIS). Using data for the early 1980s, the results indicate that the income distributions in Australia and New Zealand are not, as previous research has suggested, more equal than those in other countries. Neither country has an equivalent net family income inequality ranking in the top half of the eight countries studied. Further analysis indicates increasing inequality in Australia in the first half of the 1980s and, on the basis of some indicators, in New Zealand also. The paper does not investigate the causes of these increases in inequality, although the results indicate that the rise in property income has been a factor behind them.     

PROBLEMS OF INTERNATIONAL COMPARISONS OF NATIONAL ACCOUNTING AGGREGATES BETWEEN COUNTRIES WITH DIFFERENT ECONOMIC SYSTEMS

This paper discusses a number of problems arising in comparisons of levels of national accounting aggregates between countries with different economic systems, notably between countries with market economies and countries with centrally planned economies. It considers problems arising from differences in the national accounting concepts used and problems arising from institutional differences, both of which are viewed as relating to the concepts on which the comparison should be based and the adjustment of national data to these concepts. The final section considers index number problems.     

INTERNATIONAL COMPARISONS OF REAL PRODUCT AND ITS COMPOSITION: 1950–77

Structural relationships estimated from data obtained in a benchmark study of the expenditures and prices of 16 countries are used to develop a table of real gross domestic product and shares of gross domestic product devoted to private and public consumption and investment for each of over 100 countries in the years 1950 and 1960 through 1977. Price level estimates for total product and the three components are also provided.     

PROTECTION BY TARIFF BARRIERS AND INTERNATIONAL TRANSACTION COSTS

Using estimates of protection in the EU market against US exports, this paper illustrates the relative importance of natural and policy sources of protection and the measurement errors induced in the measurement of effective protection by omitting transactions costs. It also considers protection in the EU ‘domestic’ and export market, and the implications of the elimination of tariff barriers only on relative rates of protection in ‘domestic’ and export markets.     

FAMILY INCOME,AGE, AND SIZE OF UNIT: SELECTED INTERNATIONAL COMPARISONS*

Two aspects of the relationship between family unit income and the age of the head of the family unit are examined in this exploratory paper. First, in connection with the recent discussion in the U.S. about the “fair” level of income of the aged population, the economic well-being of various age of head groups is examined for the U.S., Canada, Norway, and Israel. Problems inherent in comparing income distributions across countries are described briefly, and the sensitivity of the estimates to definitional differences is discussed. Relative incomes of the different age groups are then compared within and between countries. Relative mean incomes, relative median incomes, relative mean incomes adjusted for size of unit in alternative ways, distributions of age groups among income quintiles, and relative income shares within age groups are compared. The focus is on aged units. It is found that, using these crude measures, aged units in the U.S. are roughly as well off relative to the other age groups as aged groups in the other countries examined. In the second section of the paper, a U.S. microdata file is reweighted to be consistent with the distributions by age of head of Norway and Canada. Relative income shares of quintiles are computed before and after reweighting and compared with the shares for Norway and Canada. The reweighting to Norway's age distribution increased differences in relative income shares between the two countries; the reweighting to Canada's age distribution slightly decreased differences.
