A DISEQUILIBRIUM ECONOMETRIC MODEL OF THE AUSTRALIAN RAW WOOL MARKET*

This paper develops a quarterly disequilibrium model of the Australian wool market. It is postulated that because of inherent market imperfections the market does not clear. The model consists of demand and supply equations for both private and government traders, a minimum condition to determine quantity transacted and a price adjustment equation based on excess demand/supply. Effective demand/supply concepts which recognise the expectation of rationing are employed to model private demand/supply. Supplier price expectations explicitly account for the lower bound imposed by the minimum reserve price scheme (RPS). The estimates suggest that the disequilibrium hypothesis cannot be rejected, as a consequence measures of market imbalance are provided. The model is also used to simulate the effects of the removal of the RPS.     

Climbing the Job Ladder: New Evidence of Gender Inequity

An explanation for the gender wage gap is that women are less able or less willing to “climb the job ladder.” However, the empirical evidence on gender differences in job mobility has been mixed. Focusing on a subsample of younger, university‐educated workers from an Australian longitudinal survey, we find strong evidence that the dynamics of promotions and employer changes worsen women’s labor market position.     

MEASURING PRICE ELASTICITY OF SECTORIAL IMPORTS

Previous published studies have estimated the long‐run cointegrating relationship to infer the price elasticity of imports, but a stable long‐run cointegrating relationship might not be detected in the data, especially in the case of sectoral data. This paper develops a method to estimate the price elasticity of imports based on a vector autoregression model, which can be applied when a stable long‐run cointegration relationship does not exist. The methods developed in past studies and our method are applied to Korean sectoral imports data to illustrate the usefulness of our method.     

INFLATION TARGETING IN PRACTICE: FURTHER EVIDENCE

This paper empirically investigates the plausibility, which has been argued but not fully established, that the efficacy of the inflation-targeting strategy recently implemented by New Zealand, Canada, and the U.K. has been an artifact of a global disinflationary environment. A data decomposition procedure, which involves cointegration and canonical correlation analysis, is used to remove common trend and cyclical components from historical data that these three countries share with their nontargeting neighboring countries, namely, Australia, the U.S., and Germany, respectively. Simulations based on resulting country-specific data for inflation and other economic aggregates reveal scant evidence of regime-shift effects as exhibited in observed data. This contrast in findings highlights the extent to which cross-country synchronization in economic activity has on the performance of small open economies. (JEL C32, E52, E58)     

Optimal Schooling Investments and Earnings: An Analysis Using Australian Twins Data

The potential impact that unobserved ability can have on both schooling and earnings outcomes has been modelled by Ashenfelter and Rouse (1998). This paper applies their model to the Australian Twins Sample. The best estimate of the return to schooling for genetically identical (or MZ) twins is 8.9 per cent. Measurement errors in the schooling data are shown to constitute a more serious problem than the omission of the family effects that impact on ability. Individuals from higher ability families receive a lower marginal benefit from their investment in human capital.

A study on the subjective symptoms of the ageing process in middle-aged men: effects of socio-economic status,diet and health care behaviour*

In order to investigate the factors influencing the ageing process of middle-aged men, different environmental variables including socio-economic status, diet, smoking and drinking were studied as possible determinants of the ageing process. Six hundred and forty-seven Korean men over 40 years of age were studied. Frequency, chi-square, t-test, and stepwise multiple regression analyses were employed to identify the significant variables. As a result of the analyses, occupation and smoking were found to be the most influential factors. In short, those who did not refrain from smoking and had professional jobs experienced early symptoms in the ageing process.
