Undereducation and Overeducation in the Australian Labour Market*

This paper uses data from the 1996 Census of Population and Housing Household Sample File (HSF) to study the incidence of mismatch between workers' educational attainments and the requirements of their jobs, and the earnings consequences of this mismatch. It also examines whether mismatch contributes to the explanation of the gender wage differential in the Australian labour market. It is found that approximately 15.8 per cent of men and 13.6 per cent of women are overeducated, whereas approximately 18.5 per cent of women and 13.7 per cent of men are undereducated. Substantial earnings consequences are found to be associated with this mismatch, with surplus schooling yielding relatively low returns. The results suggest that mismatch does not account for the gender wage gap in the Australian labour market; rather the gender wage differential is entrenched in the fundamentals of pay determination.     

The Impact of Incomes Policy on Aggregate Wage Determination in Australia*

A model of aggregate wage determination for Australia is developed and used to examine the effects of incomes policies on the level of real wages. A theoretical model of wage determination which includes several channels of incomes policy effects is specified and estimated using aggregate data. The results provide strong evidence to support the view that during periods of certain incomes policies there have been important changes in behaviour in the Australian labour market. In particular, during the period of the Prices and Incomes Accord it is estimated that equilibrium real wages were over 5 per cent below what would have been expected from previous experience.     

Caste discrimination in the Indian urban labour market: An econometric analysis

This paper uses Degree Holders and Technical Personnel Survey of India to examine the wage gap between Non-Scheduled Castes/Tribes(NSC) and Scheduled Castes/Tribes(SC/ST). Separate wage equations, corrected for selection bias, are estimated for NSC and SC/ST. The parameter estimates of the wage equations were decomposed into ‘endowment’ and ‘treatment’ components using the familiar Oaxaca Decomposition Method. A separate account was also made to analyze the interaction between occupational attainment and the wage differential using the extended decomposition method. The main conclusion from the econometric results are: (a) the endowment difference is higher and discrimination causes 15 per cent lower wages for SC/ST as compared to NSC; (b) the discrimination coefficient is negative in the public sector whereas it is positive in the private sector; (c) intraoccupational wage effects dominate. The higher endowment difference in developing countries like India implies that the pre-market discriminatory practice with respect to education, health and nutrition are more crucial than labour market discrimination.

The Economic Situation

Throughout the first nine months of 1976 the Australian economy has remained virtually stagnant, with output and employment increasing only marginally and unemployment rising also. With the government following a severely contractionary policy in an attempt to break inflation the economy seems poised for a further modest downturn in the next nine months so that a self-sustaining recovery from the current recession does not seem to be in prospect before the second half of 1977. On the basis of existing policies our forecasts indicate a rate of growth of real GDP of only about 1.0 per cent in 1976–77, implying a further significant rise in unemployment during the financial year. There have been some hopeful signs in recent months of a reduction in inflation — the consumer price index increases in the first three quarters of 1976 were modest and wage rate increases remain closely in line with the wage indexation guidelines — but three factors have emerged to cast doubt on whether this improving trend will continue. The first is the effect of the recent drought on prices of foodstuffs, particularly meat, and the second is the expected 1.5 to 2.0 per cent increase in the consumer price index as a result of the changes in the method of financing hospital and medical services. These two factors mean that the December quarter increase in the consumer price index may be more than 5 per cent, threatening a further stimulus to inflation in 1977. Thirdly, present government policies could easily lead to a breakdown of the wage indexation system and a return to some form of collective bargaining over wage rates. Assuming nevertheless, a de facto continuation of partial indexation in 1977, we expect increases in male award wages and male average earnings of about 13 per cent during 1977, these increases being similar to those during 1975 and 1976 but much below the increases of 36 per cent and 28 per cent respectively recorded during 1974. Our forecasts also indicate increases in the consumer price index of 14 per cent during 1976 and 11 per cent during 1977, following increases of 16.3 per cent and 14.0 per cent during 1974 and 1975 respectively. These forecasts indicate that the government's fiscal, monetary, exchange rate and wage policies are likely to come under heavy challenge early in 1977, and decisions taken at that time are likely to be major determinants of economic developments in Australia in the next few years. The Institute would again urge a shift to a co-operative package including full wage indexation, with cuts in indirect taxes and public sector charges to wind down inflation and expand the economy. On current indications, labour productivity will be no higher in 1976–77 than in 1973–74, because of the weakness of total output, so that the whole burden of wage increases in that three year period has fallen on unit costs of production. It is our belief that the twin problems of inflation and unemployment will only be defeated in Australia when both cuts in indirect or direct taxes and increases in productivity are applied to reducing inflation in the context of an orderly system of wage and price determination.     

Its Bark is Worse Than its Bite: The Wage and Employment Effects of the Minimum Wage in the US

This study examines the effect of changes in the US minimum wage on wages and employment in 32 industries selected for their presumed sensitivity to the minimum wage. Applying time series techniques commonly used in macroeconomics and finance to changes in the minimum wage occurring from 1967 and 1991, we initially test for a wage response; only where one is found do we test for an employment response. Twenty-five per cent of the industry/minimum-wage-increase pairs show evidence of an appropriate wage response. Eight of these 54 show a statistically significant negative employment response, while six show significant, positive employment responses. Positive effects may be due to either a high variance distribution centred on zero or markets with 'lemons' problems concerning worker quality. Limiting analysis to industries in which the minimum wage binds provides no evidence of a consistent negative relationship between the historical minimum wage and employment.     

The Contribution of Intermittent Labour Force Participation to the Gender Wage Differential*

Despite equal pay decisions in 1969 and 1972 a gender wage differential of around 15 per cent exists in 1990. This paper uses information on the number of years worked from the 1984 National Social Science Survey to provide an understanding of the role of intermittent labour force participation in the wage determination process in Australia. Differences in years worked between males and females are shown to account for approximately 40 per cent of the gender wage gap. The analyses also reveal that males receive higher returns for each additional year of schooling than females     

The Henderson Question? The Melbourne Institute and 50 Years of Welfare Policy

I discuss selected research contributions of the Melbourne Institute of Applied Economic and Social Research to 50 years of welfare policy for those of workforce age and focus particularly on the policy focus of R. F. Henderson, the inaugural director. Following the spirit of his 1960s poverty research, in the mid‐1970s, government doubled unemployment allowances in real terms and increased pensions by approximately 40 per cent. Both income support payments were to be indexed by average wage increases. At the time, unemployment was typically around 1 per cent and the pension take‐up for those of workforce age was also limited. Today, income support take‐up rates have probably increased fivefold. In response, government has adopted a ‘make work pay’ policy over the last two decades and indexed allowances for Consumer Price Index increases and allowances have fallen by 25–35 per cent, relative to community living standards. Pensions continue to be indexed by average wage changes. I address a range of questions arising from this experience, including: Why has government abandoned the Henderson recommendations?; Is there any evidence that a ‘make work pay’ policy is working?

     

The Social Return to Apprenticeship Training

This paper draws together findings from a recent program of research to estimate the social rate of return to apprenticeship training and how the costs of training are distributed. It is estimated that 53 per cent of the costs of training an apprentice are borne by the employer, 28 per cent by the public sector and 19 per cent by the apprentice. This is in sharp contrast to the prediction of economic theory that trainees pay for general training. The social rate of return to male apprenticeships is estimated to be 12.8 per cent. This is in line with previous estimates of the social rate of return to university degrees and supports the case for policy measures to increase the level of apprenticeship training. Reforms taking place under the New Apprenticeships Systems are intended to shift the distribution of costs in line with that predicted by theory by placing a greater cost burden on apprentices for general training and increasing the specificity of training. If employers' willingness to offer apprenticeships has been a constraint, then these changes should stimulate apprenticeship training.     

Union Wage Effects and the Probability of Union Membership*

This paper uses Lee's (1978) model to determine the wage gains associated with trade union membership and the reasons individuals join trade unions in Australia The data are derived from the 1984 Australian National Social Science Survey. A major conclusion is that unions secure a 17.22 per cent wage gain for their members, other things the same. This expected wage premium is shown to have an important positive impact upon the union membership decision. The welfare loss associated with the union wage premium is argued to be relatively minor about one half of one per cent of gross domestic product     

Work and Wage Dynamics around Childbirth

In this paper, we investigate how the wage processes of women who are well established in the labour market are affected by having children. We estimate a flexible fixed‐effects wage regression model extended by post‐childbirth fixed effects. We use register data on West Germany, and we exploit the expansionary family policy during the late 1980s and 1990s for identification. On their return to work after childbirth, the wages of mothers drop by 3–5.7 per cent per year of leave. We find negative selection back to full‐time work after childbirth. We discuss the policy implications regarding statistical discrimination and the results concerning the family gap.

Empirical determinants of physician incomes — Evidence from Canadian data

This paper makes use of the fact that the stock of medical manpower in Canada is institutionally and exogenously determined in order to develop a model predicting physician average net income. An econometric evaluation of this model on a sample involving Canada's ten provinces during 1968–1982 suggests that a one per cent increase in physician fees increases physician average net income by 0.70 per cent, and a one per cent increase in the physician to population ratio reduces average net income by 0.62 per cent. In both cases, the elasticities are less than unity because the supply function for an individual physician is backward bending — on average, a Canadian physician reduces his hours worked by an amount between 0.17 and 0.50 per cent (95 per cent confidence interval) if his real wage rate is increased by one per cent.     

Income Growth and Earnings Variations in New Zealand, 1998–2004

This article analyses changes in the distributions of working‐age individuals' earnings and total income in New Zealand over the period 1998–2004. We find that there have been broad gains in income across the distribution, suggesting the spoils of growth have been shared widely. Mean and median earnings increased 15 and 23 per cent respectively, while mean and median income increased 12–13 per cent. Inequality, as measured by the Gini coefficient, was more stable: earnings inequality fell 4 per cent, while income inequality was unchanged. The main drivers of the changes were employment and real wage growth. We estimate that roughly one‐half of the growth in average incomes was due to employment growth, and one‐quarter each to demographic changes and wage growth. The relative employment and wage contributions varied across the income distribution: employment growth dominated gains at the lower end of the distribution, while wage gains dominated changes at the higher end.     

Schooling choices: Preferences, discount rates, and rates of return

This paper develops an empirical model to identify the structural parameters of schooling preferences and human capital production. Our model distinguishes between consumption and investment motives with regard to schooling. The results show that both motives matter. Preferences for schooling vary with social background and ability. Children from poorer social backgrounds and of lower ability have a lower preference for schooling. The discount rate that enters the net value of lifetime income varies with social background as well. The marginal rate of return to schooling decreases with ability and schooling. On average the marginal rate of return is 7.3 per cent, which can be contrasted with a `Mincerian' rate of return equal to 4.8 per cent. This indicates that the usual OLS estimate underestimates the true rate of return. First version received: November 1997/Final version received: February 1999     

Public–Private Sector Wage Differentials in Australia

This paper examines public–private sector wage differentials in Australia. After controlling for observed characteristics and individual fixed effects, we show that on average workers in the public sector earn about 5.1 per cent more in hourly wages than those in the private sector. The wage premium is slightly higher for females than males. Using a panel data quantile regression model with fixed effects, we show that the positive wage effects of public sector employment are heterogeneous, with comparatively larger impact at the lower end of the wage distribution than at other parts. We also find evidence of heterogeneity in the public sector wage premiums by qualification, time period, occupation and state/territory.     

Wages in a growing Russia

The robust Russian economic recovery after the 1998 financial crisis raised the economic standing of the population, especially for lowly paid workers, most of whom are women. In this paper I use the Russian Longitudinal Monitoring Survey from 1996 through 2002 to ask whether this helped to reduce the gender wage gap. I first focus on those whose wages are paid in full. Next, I ask about the gender composition of wage arrears as the overall extent of wage arrears dropped from 60 to 20 per cent after the 1998 crisis. I show that a temporary widening of the overall gender wage gap in 2000 is due to low‐wage women becoming more likely to receive their wages in full than low‐wage men. Except for this effect, the male–female pay difference in Russia exhibits a stable pattern.     

Increasing wage dispersion and the changes in relative employment and wages in Mexico's urban informal sector: 1987-1993

This study analyses the role of changes in informal/formal relative employment, wage levels and wage inequality in explaining increasing wage dispersion in Mexico during the 1987–1993 period. From 1987 to 1993, the variance of the log of hourly wages for Mexican workers increased by more than 50 per cent. Using data from the Encuesta nacional de empleo urbano we find that this increase in the overall wage dispersion was mainly driven by increasing wage dispersion in the formal sector coupled with a faster growth in formal sector employment as a percentage of total employment. However, compression in the distribution of wages within the informal sector contributed to substantially slowdown the increasing overall wage inequality. About 60 per cent of the 1987–1993 4.65 percentage point reduction in the informal sector share of total employment is explained by changes in the structure that determines sectoral employment; the rest is explained by changes in the composition of the labour force, particularly increases in the sectoral education gap and a change in the regional relative share of sectoral employment. Also, from 1987 to 1993 the sectoral wage ratio increased from 0.59 to 0.63. It seems that a relative improvement in unobserved skills in the informal sector helped to close the wage differential but this effect was partially offset by an increase in the relative prices of both observed and unobserved skills, as well as increases in relative observed skills in the formal sector, particularly education.     

Work Effort, Moderation in Expulsion, and Illegal Migration

Illegal migrants supply a valuable productive input: effort. But their status as illegals means that these migrants face a strictly positive probability of expulsion. A return to their country of origin entails reduced earnings when the wage at origin is lower than the wage at destination. This prospect induces illegal migrants to exert more work effort than comparable workers who face no such prospect. The lower the probable, alternative earnings, the harsher the penalty that illegal migrants will be subjected to upon their return, for a given probability of expulsion, and the higher the level of effort they will exert at destination. While the home‐country wage that awaits the illegal migrants upon their return is exogenous to the host country, the probability of their return is not. Given the home‐country wage, a higher probability of expulsion will induce illegal migrants to supply more effort. Hence, different combinations of probabilities of expulsion and home‐country wages yield the same level of effort. Thus, variation in the extent to which receiving countries undertake measures aimed at apprehending and expelling illegal migrants can be attributed not to characteristics of the illegal migrants themselves but to a feature that pertains to the illegal migrants’ country of origin.     

The wage effects of training in Portugal: differences across skill groups,genders, sectors and training types

This article investigates the determinants and wage effects of training in Portugal. In a first stage, we show that there are considerable differences in training participation across groups of workers, with elder and low educated individuals participating substantially less. In a second stage, we show that training has a positive and significant impact on wages. The estimated wage return is about 30% for men and 38% for women. Discriminating between levels of education and working experience and the public and private sector reveals important differences across categories of workers. We find that women, low educated workers and workers with long working experience earn larger returns from training. The average effect of training is similar in the private sector and the public sector. However, differences across experience groups are larger in the private sector, while differences across education groups are larger in the public sector. We use three alternative classifications of training activities and find that training in the firm, training aimed to improve skills needed at the current job and training with duration less than a year are associated to larger wage gains.     

Why Has Australian Wages Growth Been So Low? A Phillips Curve Perspective

Wages growth in Australia has recently been the lowest in two decades. One possible explanation is a decline in the non‐accelerating inflation rate of unemployment (NAIRU). We examine this hypothesis by estimating a wage Phillips curve including a time‐varying NAIRU. Our findings are: (i) the NAIRU has recently been around 5.5 per cent; (ii) our approach increases the precision of the NAIRU estimates; (iii) low inflation expectations have been an important contributing factor; and (iv) the long‐run annual wages growth is nearly 3 per cent. We also find that the underutilisation rate suggests greater slack exists, but is less useful in explaining wage developments.
