PRODUCTION FUNCTIONS AND THE DISAGGREGATION OF LABOR INPUTS IN MANUFACTURING PLANTS*

ABSTRACT. This paper investigates the assumption of homogeneous labor inputs underlying the production functions in many regional models. The results indicate that nonproduction and production labor within manufacturing plants are not strongly separable, and the homogeneous labor assumption is not therefore appropriate. Hence, regional models need to take this into account in order to give reliable results. Differences between industries provide useful additional insights into their labor and capital relationships.     

A LINEAR PROGRAMMING APPROACH TO SOLVING INFEASIBLE RAS PROBLEMS

ABSTRACT The RAS procedure is widely used to update national and regional input-output tables and international trade tables and to construct regional tables from national ones. Special problems, however, have been encountered when the procedure is used to adjust interregional trade tables. In this paper, the special properties of interregional trade tables that increase the likelihood of nonconvergence of the RAS procedure are discussed, and two linear programming methods of solving infeasible RAS problems are provided. First, a closed linear programming approach, which enables exogenous information to override the purely mechanical solution of infeasible RAS problems, is presented. Finally, the open linear programming approach is applied successfully to adjust U.S. interregional trade data that had previously failed to converge using the RAS procedure.     

STRUCTURAL ANALYSIS OF THE POLICE-TRACKER STORY GENRE IN GOONIYANDI

This paper investigates the structure and socio-cultural functions of a class of narrative texts in the Gooniyandi language of the Fitzroy Crossing area (Kimberley, W.A.). These are ‘police-tracker stories’: narratives relating actual incidents involving the police and police trackers; most are autobiographical accounts told to me by Jack Bohemia, a former police tracker. It is argued that the texts of this type constitute a genre, characterised structurally in terms of episodes: all the texts consist of a set of seven inherent episode-types, six of which form two ternary episode-sequences. A variety of other, optional episodes may also occur. The episodal structure of the texts reflects, in an iconic way, their socio-cultural meanings and the narrator's ideology. It is argued that the texts represent an ideology of place as the organising principle for past experiences; and that they project a moral view of the world, in which ‘crimes' are ‘punished’. Some brief comments are also made rejecting the category label ‘oral history’.
