The UK demand for steel

The paper suggests a short-run model of the demand for steel that may be used for forecasting future trends. The paper commences with consideration of a long-run model which is estimated using cointegration analysis. An error correction model is then developed to depict the short-run movements to equilibrium. This can be used for the purpose of ex-post forecasting.     

Saltatory Ontogeny and the Life-History Model: Neglected Processes and Patterns of Evolution

A single cell – an egg – cannot be in the same stabilized state as a differentiated multicellular embryo or reproducing adult. The entire ontogeny must, therefore, consist of a sequence of stabilized states. Ontogeny of a phenotype cannot progress gradually but is a saltatory homeorhetic system, proceeding via natural thresholds from one self organized state to the next, hierarchically ever more complex and specialized. The natural boundaries of ontogeny – the far-from-stabilized thresholds – represent also states when changes can be easiest inserted or induced, and especially in the early ontogeny, from the intervals where evolution (change) can occur. As a result, ontogeny can also be divided into distinct life-history intervals called periods, be it embryo, larva (infant, pup), juvenile, adult and senescence, each divided in turn into phases, and each of these into natural steps. It is left to the imagination of scholars in social sciences to find parallels of saltation in economics and history.     

A note on the interpretation of the Cox procedure for non-nested hypotheses

This note demonstrates that the Cox procedure for non-nested hypotheses yields only four possible conclusions. Therefore, if a researcher draws any implications upon rejection of a null hypothesis, the inference could be misleading.     

An Analysis of Occupational Outcomes for Indigenous and Asian Employees in Australia

This paper examines occupational performance in Australia across three racial groups in Australia: Indigenous Australians; Asian people, defined as all those whose language spoken at home was either Chinese, Vietnamese or other forms of a South-east or East Asian language; and white people, defined as the residual category. The paper has as its starting point, observed differences in occupational attainment among the three groups in Australia and sets out to account for these observed differences on the basis of both race and non-racial attributes such as, age, education and area of residence.     

Regional welfare loss meaures of the 1973 oil embargo: a numerical methods approach

A simple exercise of time-series analysis shows that the presence of the phonomenon of temporal aggregation in quarterly consumption data can substantially alter the empirical inference about Hall' mocel of consumption behaviour. This fact has received almost no attention in the econometric research in this field.
