Decomposing differences in labour force status between Indigenous and non-Indigenous Australians

Despite several policy efforts to promote economic participation by Indigenous Australians, they continue to have low participation rates compared to non-Indigenous Australians. This study decomposes the gap in labour market attachment between Indigenous and non- Indigenous Australians in non-remote areas, combining two separate data sources in a novel way to obtain access to richer information than was previously possible. It shows that among women at least two thirds of the gap can be attributed to differences in the observed characteristics between the two populations. For men, the differences in observed characteristics of the two populations can account for 36 to 47 percent of the gap. A detailed decomposition shows that lower education, worse health, and larger families (particularly for women) explain the lower labour market attachment of Indigenous Australians to a substantial extent. Compared with previous studies, this study is able to explain a larger proportion of the gap in employment between Indigenous and non-Indigenous people due to being able to include a larger set of explanatory variables.

The Impact of Intergovernmental Grants on Cost Efficiency: Theory and Evidence from German Municipalities

In this paper we use a simple bureaucracy model of fiscal illusion to analyze the impact of intergovernmental grants on the cost efficiency of local jurisdictions. We find that a higher degree of redistribution within a system of fiscal equalization or an increase in the amount of grants received by a local jurisdiction leads to an extension of organizational slack or X-inefficiency in that jurisdiction. This theoretical prediction is tested by conducting an empirical analysis using a broad panel of German municipalities. The results of the empirical analysis are consistent with the theoretical findings and therefore support the existence of a negative incentive effect of intergovernmental grants on local authorities' cost efficiency. --Cost efficiency,Fiscal equalisation,Intergovernmental grants,Bureaucracy,Stochastic frontier analysis,German municipalities

What determines local governments' technical efficiency? The case of road maintenance

In this paper we investigate the determinants of local governments' technical efficiency in road maintenance for a panel of German counties using a broad variety of estimation approaches. More specifically, we calculate efficiency indices using non-parametric (DEA) and parametric (stochastic frontier analysis) reference technologies, and examine how these efficiency indices can be explained by estimating and comparing four different regression models. The results of our analysis show that (controlling for numerous characteristics of the counties) the disposable income of the counties' citizens, intergovernmental grants (for county roads), and the payments to the counties influence efficiency negatively. Concerning political variables we find weak evidence that efficiency decreases with an increasing share of seats of left-wing parties in the county council; the hypothesis that efficiency decreases with the degree of political concentration in the county council could not be confirmed. --Technical efficiency,road maintenance,stochastic frontier analysis,data envelopment analysis,German counties

Numerical simulation of mesoscale precipitation

The numerical simulation of mesoscale precipitation as well as the development of software and appropriate computer techniques are investigated. The development of a mesoscale model and the means to incorporate meteorological data into the model are examined

New Zealand Labour Supply from 1991-2001: an analysis based on a discrete choice structural utility model

This paper presents results for four separately estimated sets of discrete choice labour supply models using the Household Economic Surveys from 1991/92 up to 2000/01. The New Zealand working-age population is divided into sole parents, single men, single women, and couples. The labour supply models use imputed wages for the non-workers. Some of the preference parameters for work and income are made dependent on personal and household characteristics to allow for heterogeneity in preferences among households. In addition, allowance is made for unobserved heterogeneity in preferences. The estimated parameters for the different groups are used to calculate confidence intervals for expected labour supply and the probability of working at the different discrete hours points. The effect of particular characteristics on labour supply is illustrated by computing marginal effects across the samples. The wage elasticities fall within the range of values found in other studies. Expected labour supply, predicted by using the estimated models, results in values close to the observed averages and confidence intervals around the expected values are reasonably narrow in most groups. The results are as anticipated and similar to results in other countries, with preferences for work being higher for people with higher education, who are in their thirties. Furthermore, for women the presence of young children decreases the preference for work. In addition to these variables, which are usually included in labour supply models, the “eligibility for New Zealand Superannuation†indicator and a “living with parents†indicator are included. For all groups, the delayed eligibility for the state provided superannuation scheme is found to increase labour supply. The indicator for living with one’s parents is found to increase labour supply for sole parents (indicating that living with one’s parents may be a childcare strategy), although the effect was not significant.New Zealand labour supply; discrete choice labour supply model; simulated maximum likelihood; simulated confidence intervals

Behavioural Microsimulation Modelling With the Melbourne Institute Tax and Transfer Simulator(MITTS) : Uses and Extensions

This paper describes microsimulation modelling in non-technical terms; and it explains what can be achieved with microsimulation modelling in general, and the Melbourne Institute Tax and Transfer Simulator (MITTS) in particular. The focus is on behavioural microsimulation modelling, which takes individuals’ labour supply responses into account when analysing tax and transfer reforms. Microsimulation models are built to replicate closely the considerable degree of heterogeneity observed in the population. Several examples of recent uses of MITTS are given and briefly described. In addition, one worked-out example is presented to illustrate some of the features and typical outputs of MITTS. Given the relatively recent development of behavioural microsimulation models, there are several opportunities for further extensions. For example, it would be valuable to allow for the demand side of labour, indicating whether new labour force participants are likely to find work; or to allow for life-cycle dynamics, which are important to deal with population-ageing issues or with female labour force participation.

Wage and Employment Rates in New Zealand from 1991 to 2001

This paper presents results for five separately estimated sets of employment and wage equations. The New Zealand working- age population is divided into sole parents, single men, single women, married men and married women. The results for the wage equations are as anticipated and similar to the results in other countries. A higher education level, living in a city and age (up to the early forties) increase the expected wage. Wages also differ significantly across industries and occupations. Employment follows the expected patterns as well, where women with children are less likely to be employed; education increases the employment probability; and living in remote areas decreases employment. In addition to the usual variables, unemployment affects the probability of employment negatively and a clear upward time trend is observed for sole parents, living with one’s parents decreases the employment probability of singles but increases the probability for sole parents, and eligibility for the New Zealand Superannuation seems relevant in the employment decision.Wage rate; employment; joint model specification
