Analyzing Income Distribution in Australia*

This paper contains an analysis of the sources of income inequality in Australia, based on data from the ABS income survey for 1978-79. The analysis proceeds by progressive decomposition of the population into component groups differentiated by characteristics such as sex, age, employment status and occupation. At each stage of the decomposition, total inequality is partitioned into contributions from within and between the component groups, as measured by the Shorrocks Iq index. The importance of the characteristic in question as a source of inequality can then be assessed. While the results of the analysis are described in some detail, the emphasis of the paper is primarily methodological.     

Economic Growth and Income Support Policy in Australia*

This paper examines the growth in welfare spending in Australia over the 20 years from the early 1960s to the early 1980s. Particularly for pensioners and beneficiaries with children, the levels of benefit and high tax rates implicit in the tax and social security systems are shown to create disincentives over wide ranges of private income. A careful examination of the evidence indicates that more generous levels of benefits had a modest but significant part in the growth of unemployment since 1970. The paper concludes by suggesting that the efficiency costs of meeting society's distributional objectives can be minimized by targeting assistance to the most needy and by the careful use of income testing.     

Longer Run Changes in the Distribution of Income in Australia*

This paper brings new evidence to bear on the question of changes in income distribution amongst individuals in Australia between 1942–43and 1989–90. The changes observed over this period are analyzed in the context of previous studies of the changing distribution of income in Australia over the past 80 years. The main conclusions of the paper are that the distribution of individual income in J 989–90is very similar to that estimated for 1942–43, and there is evidence that income inequality has been increasing during the 1980s     

Consumption and Income Inequality in Australia

Consumption may be a more appropriate measure of household well-being than income or earnings. Using four ABS Household Expenditures Surveys collected between 1975 and 1993, we compare trends in consumption and income inequality among Australian households. We find that consumption is much more equal than income. While there were significant increases in both income and consumption inequality, consumption inequality rose by much less. One interpretation of the results is that some income inequality in Australia reflects transitory fluctuations which households can smooth,'and that part of the growth in income inequality reflects an increase in these transitory fluctuations.     

Income and Health Concentration in Australia

This paper measures the concentration of ill-health among income groups in Australia using health survey data from 1989–90 ( Australian Bureau of Statistics 1991 ) and 1995 ( Australian Bureau of Statistics 1997 ), which contain responses on self-assessed health status and gross personal income. The technique of direct standardisation is used to control for the influence on health status of gender and age. Comparisons of the concentration of ill-health over time and between males and females and persons living in rural and urban areas are reported. For both surveys and all groups, we find that ill-health is concentrated among lower income groups. Concentration measures of ill-health are higher (in absolute terms) for men than for women. In all categories apart from women, the concentration measures fell between 1989–90 and 1995 surveys.     

Taxation Reform and Income Distribution in Australia

This article contains an analysis of the effects of changes in the existing tax mix on the distribution of income in Australia. Shifts from direct to indirect taxes, similar to ‘Option C’ in the Government's Draft White Paper on tax reform, are considered. The general equilibrium effects of the policy changes are analysed using an extended version of the ORANI model of the Australian economy. The Shorrocks I₀ index is then used to identify the sources of inequality in the pre- and post-change distributions. The results are based on data from the ABS Income and Housing Survey for 1981–82.     

Lost Exceptionalism? Comparative Income and Productivity in Australia and the UK, 1861–1948*

Australia had one of the highest per capita incomes in the world in the late nineteenth century, although this exceptional position subsequently eroded over time. This paper compares national income and sectoral labour productivity in Australia and the UK between 1861 and 1948 to uncover the underlying sources of Australia's high income and the reasons for its subsequent relative decline. We find that the country's higher per capita income was due primarily to higher labour productivity, because labour force participation, although higher in Australia than in the USA, was lower than in the UK. Australia had a substantial labour productivity lead in agriculture throughout the period, due to the importance of high value-added, non-arable farming, and a smaller lead in industry before World War I. The early productivity lead in industry was largely based on the importance of mining, and disappeared as manufacturing became more important. There was little productivity difference in services. These results reaffirm the importance of Australia's successful exploitation of its natural resource endowments in explaining the country's high initial income.     

Skilled Immigration and Wages in Australia*

This paper investigates the impact of the relative growth of skilled migration on the structure of Australian wages. Unlike conventional approaches, the present study uses macro data to examine the response of wages to immigration flows. We use instrumental variable techniques to control for the potential endogeneity of immigration. The results, using alternative estimation strategies, are consistent with the dominant findings from existing empirical work. There is no robust evidence that a relative increase in skilled immigrants exerts any discernible adverse consequences on the wage structure in Australia.     

Share Ribs and Income Distribution*

The connection between changes in commodity prices and the distribution of income is a question of active interest since the 1941 Stolper-Samuelson Theorem. In higher dimensions results are obtained only if structure is imposed. Here we assume that each of n-industries is alike in the shape of the profile (rib) of distributive factor shares with a permutation of factor numbering such that industry n is most intensive in factor n. Such a structure reveals either a strong version of the Stolper Samuelson Theorem or a Neighborhood oscillation pattern depending on the shape of the share ribs.     

Statistical Inference and Changes in Income Inequality in Australia

This paper studies the changes in income inequality in Australia between 1986 and 1999, using the Gini coefficient and Theil's inequality measure. Individuals are divided into various subgroups along several dimensions, namely region of residence, employment status, occupation and age. The change in inequality over time, between and within these subgroups is studied, and the bootstrap method is used to establish whether these changes are statistically significant .     

Australia and the Pacific Economy*

The industrialization and growth of East Asian countries has shifted the centre of world trade and economic activity towards the Pacific. There has already been a huge redirection of Australia's trade and external economic interests towards the region, based importantly on the emergence of Japan as a major economic power. Australia's future economic prospects will be significantly determined by how it manages its trade policy interests in the context of continuing East Asian industrialization. The most promising Australian trade policy approach is one which allies Australia's trading interests to those of East Asian countries in seeking to maintain an open non-discriminatory trade regime, supportive of the transformation of trade specialization necessary to the industrialization of resource-deficient countries, and which marries that objective to the liberalization of her own and Pacific country markets.     

Wage Determination In Australia*

This paper examines whether a stable expectations-augmented Phillips curve exists for Australia. High real wages in the face of continuing high unemployment over the past decade have led to suggestions that the level of unemployment has little effect on wage determination, with the bargaining process taking place between employers and those employees in ‘secure employment’. Results from aggregate data suggest that the level of unemployment is relevant to wage determination. In addition, the impact of overtime on the growth in money wages is consistent with the view that those in secure employment are influenced by labour market conditions.     

The Relationship between Personal Income and Net Worth in Australia

This article uses data from the Household, Income and Labour Dynamics in Australia (HILDA) Survey to examine the changing distribution of net worth with age. Even after controlling for age, the relationship between income and net worth is positive, except for the older age groups. Inequality falls as age increases. The income poor save in different forms compared with high income individuals of the same age cohort. Holdings of financial assets, especially equity investments and superannuation, are heavily concentrated in the hands of high income earners, while fixed income investments are favoured by the elderly for all income groups.     

The Youth Labour Market in Australia*

This paper uses unit record data from the 1985 Australian Longitudinal Survey to review the major features of the youth labour market. It is shown that education plays an important role in determining the incidence of unemployment, wages, hours of work and access to training opportunities. Analyses of labour market dynamics indicates that the probability of leaving unemployment falls off substantially as the duration of the unemployment spell increases. A major conclusion of the paper is that the longer term unemployed appear to be segmented from other labour market participants. An implication of this finding is that there b very little which the longer term unemployed can do at the margin to influence their success other than adopt the most productive method of job search.
