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.     

Reliance on Income Support in Australia: Prevalence and Persistence

Welfare dependence or reliance is widely regarded to have adverse consequences for both the community and welfare recipients, yet there have been few studies of the extent and nature of welfare reliance. Indeed, the concept of welfare reliance does not seem to be well defined. In the present paper, we clarify the meaning of the concept and derive reliance measures consistent with this concept. These measures are applied to describe the extent and nature of reliance on income support payments in Australia of persons aged 15–64 years, using Australian Bureau of Statistics income survey data and Australian government administrative data for income support payments.     

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.     

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.     

Immigrant Generation and Income in Australia*

Microdata for adult men from the 1981 Australian Census are used to study the determinants of income by immigrant generation. The overseas born, 30 per cent of adult males, have 5 per cent lower incomes than the native born, and ceteris paribus, 7 per cent lower incomes. Schooling and pre-immigration labour market experience have smaller effects for the overseas born. Among the Australian born, those with overseas-born parents have 4 per cent higher incomes overall, but, ceteris paribus, there is no difference. The means and partial effects of the explanatory variables among the native born are not related to the parents' nativity.     

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.     

Estimates of Cash-Based Income Tax Evasion in Australia

This article provides new estimates of the size of the cash economy in Australia over the period from 1950–51 to 1989–90. This series is used to estimate income tax revenue losses for each year and to examine the factors which influence the incentive to evade income tax.     

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 .     

Income Inequality in Australia in an International Comparative Perspective

Earlier comparative work on income distribution has tended to suggest that Australia is characterised by less income inequality than other industrialised economies. Concerns about the quality of the Australian data used in such comparisons have led to the need for more detailed assessment of the situation. The Luxembourg Income Study has been a focus for this work by bringing together microdata sets for a range of countries and reorganising them to conform to standardised concepts and definitions. This paper builds on earlier work undertaken as part of the Luxembourg Income Study by including Australia in an international comparative analysis of income distribution and redistribution. The Australian data are those from the 1981–82 Income and Housing Survey, with income tax imputed onto the data file. Results are presented for the gross and net income distributions between both families and individuals in seven countries. A common set of equivalence scales is also used to adjust for differing family needs. The results indicate that, using several summary measures of inequality, the distribution of income in Australia is less equal than in four of the other six countries studied. Earlier research which placed Australia high on the international league table of income equality is thus not confirmed by the results.     

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     

Towards a Negative Income Tax System for Australia

The undue complexity of the Australian tax-transfer system is outlined as are the associated high effective marginal tax rates for many individuals and families. A negative income tax system is a possible solution to these problems.
The most radical version of negative income tax is a 'basic income/flat tax' system which combines universal tax credits (that vary according to presence of children, disability etc.) and a flat tax rate on private income. Using NATSEM's microsimulation model STINMOD it is found that to ensure that no current social security beneficiaries become worse off under such a system would either be very expensive to introduce or require a tax rate that is likely to be unacceptably high. Less radical versions of negative income tax are also costed, incorporating the possibility of varying tax rates, the tapering out of tax credits, and placing some restrictions on the granting of tax credits. This makes negative income tax look more feasible.
The analysis does not incorporate behavioural responses. Since the motivation for a negative income tax system is largely to achieve such responses (for example, labour supply responses), this feasibility analysis might have been unduly harsh. Research is required to incorporate behavioural responses into the analysis.     

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 Relationship between Income,Wealth and Age in Australia

This article analyses the relationship between income, wealth, wealth‐adjusted income and age in Australia using a 2009–10 cross‐sectional data set. The main findings are: (i) wealth and wealth‐adjusted income generally rise with age, while income is constant across the life cycle; (ii) both income inequality and wealth inequality rise until mid‐life and fall thereafter, while wealth‐adjusted income inequality depends on the method of calculation used, one showing a fall in later life and another showing no fall; and (iii) after income, wealth and wealth‐adjusted income inequalities are adjusted for age, underlying inequality is lower in all three cases.     

Planning Retirement Income in Australia: Routes through the Maze

Individual retirees face a daunting task when they consider how best to invest their accumulated superannuation account and non-superannuation savings. This article highlights the fact that there is rarely an obvious decision in this choice and that the optimal decision depends on a number of factors. These factors include the valuation criterion adopted, the level of benefits, the individual's income level, the means-tests, the tax rates on income and superannuation benefits and the person's life expectancy. The optimal behaviour at retirement is significantly affected by the individual characteristics of relative lifetime earnings and post-retirement rates of mortality.
