Factors affecting return to work after injury: a study for the Victorian WorkCover Authority

Johnson, David ; Fry, Tim ( 2002-12)

Speedy and efficacious return to work of recovered or recovering workers is a central objective of workers compensation authorities. However, many of the factors that facilitate return to work are not well understood. This paper aims to shed light on these issues by utilizing a sample from the administrative records of workers compensation claimants in Victoria for the financial years 1993/94 to 1997/98. We separately model payments made as pensions (weekly payments) and payments made as lump sums to meet medical purposes (non-weekly claims). Two part model specifications are employed to model both the incidence of a payment and the duration or amount of that payment. The results show that claimant characteristics, characteristics of the accident, industry, employer and insurer characteristics influence the incidence, duration and cost of workers compensation claims.
Cost focussed firms and Internet usage

Loundes, J. ( 2002-12)

This paper looks at Internet usage by Australian firms that have a cost focussed competitive strategy. The data source for this analysis is the Melbourne Institute Business Survey, conducted by the Melbourne Institute of Applied Economic and Social Research. The survey was conducted in late 2001, and targeted large Australian firms. Instrumental variables estimation found that cost-focussed organizations utilised the Internet more intensively for both internal organizational activities and external market activities than organizations that did not have a high focus on costs. However, this impact appeared greater for internal organizational activities, suggesting that these firms possibly believed that there were greater cost savings and efficiency gains-at least in terms of Internet usage-to be had in using the Internet as part of the internal operations of the organization.
Optimal employee turnover rate: theory and evidence

HARRIS, MARK ; Tang, Kam-Ki ; TSENG, YI-PING ( 2002-10)

This paper investigates the quantitative effects of employee turnover on firms' productivity.The Australian Business Longitudinal Survey 1995-98, a unique survey providing firm level data on both production and employee turnover, is used as the data source. Theoretical studies have advocated that firm specific human capital and job matching to be the two major, but competing, mechanisms through which turnover affects productivity. Our results indicate that the effect of job matching dominates when turnover is"low," while the effect of firm specific human capital dominates when turnover is"high." We identify that the optimal turnover rate - the rate that maximises productivity, controlling for other factors - is about 0.3, well in excess of the sample mean. The finding suggests that further increasing the flexibility of employment arrangement for small and medium Australian enterprises could yield substantial productivity gains.
Business use of the Internet in Australia

Loundes, J. ( 2002-10)

This paper provides summary statistics of Internet usage by Australian businesses using several data sources. Aggregate statistics are provided from the Australian Bureau of Statistics (ABS) Business Use of Information Technology. More detailed information on firm characteristics and Internet usage are provided from the Melbourne Institute Business Survey, conducted by the Melbourne Institute of Applied Economic and Social Research. Despite being a relatively new phenomenon, the academic research to date has already generated some general observations. The first of these is that Internet use is only beneficial to the organisation if it is incorporated into an overall strategy. Evidence from the Melbourne Institute Business Survey shows organisations that were strong in at least one competitive strategy (that is, operational excellence, customer intimacy or product leadership) were more likely to use particular features of the Internet than the rest of the sample. The academic research also indicates that there are significant differences in Internet adoption depending on the type of industry the organisation operates in. Again, the Melbourne Institute Business Survey shows that Internet usage does indeed vary across industries, with manufacturers more likely to use the Internet for the co-ordination of delivery arrangements, whereas the service industries are more likely to use the Internet for customer self-service and personnel benefits.

Estimation of labour supply models for four separate groups in the Australian population

Kalb, G. R. ( 2002-11)

This paper estimates discrete choice models of labour supply for couples, single men, single women and sole parents in Australia using the Income and Housing Costs Survey of 1994/1995, 1995/1996, 996/1997 and 1997/1998. These models are estimated to serve as input in a microsimulation model, where they generate the behavioural responses to policy changes. The results are according to expectations, 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. Expected labour supply, predicted by using the estimated models, results in values close to the observed average.
Economic analyses of families: existing research findings

Johnson, D. ; Kalb, G. R ( 2002-12)

This paper provides a literature review on economics of the family. In particular, where decisions of families related to marriage, fertility, labour supply and home production are concerned. First an overview of the theory on these issues is given, followed by a selection of empirical studies. Finally, the review highlights some areas of interest for future research in Australia.
Are pro-reformers better performers?

Fry, T. R. L. ; Jarvis, K. ; Loundes, J. ( 2002-09)

There appears to be widespread consensus in industry and government that a switch from centralized bargaining to an enterprise based system benefits productivity. However, research suggests that the link between bargaining structures and worker productivity is dubious and that empirical research has been unable to discover a relationship between them. In this paper we use data from Australian companies at the enterprise level and examine the links between performance and a range of human resources, industrial relations and management variables to determine whether bargaining structures do impact on performance. In particular, we investigate whether organisations that have incorporated aspects of the industrial relations reform agenda have outperformed organisations that have not. The results from the application of a treatment effects regression model show evidence that organisations adopting the industrial relations reform agenda report significantly higher levels of self-assessed labour productivity relative to their competitors, even after controlling for a number of different factor

Firm performance and investment in R&D and intellectual property

ROGERS, MARK ( 2002-07)

This paper analyses the relationship between innovation - proxied by Research and Development (R&D), patent and trade mark activity - and profitability in a panel of Australian firms (1995 to 1998). Special attention is given to assessing the nature of competitive conditions faced by different firms, as the nature of competition is likely to affect the returns to innovation. The hypothesis is that lower levels of competition will imply higher returns to innovation. To allow for a time lag time before any return to innovation, the market value of the firms is used as a proxy for expected future profits. The results give some support for the main hypothesis: the market's valuation of R&D activity is higher in industries where competition is lower. However, the paper highlights the difficulty in assessing competitive conditions and finds a number of results that challenge the simple hypothesis.
