The influence of regionalization and psychic distance on the direction of Australian exports

International business research has identified separately two distinct influences on the direction of firm internationalisation. One of those influences is psychic distance, the other is regionalisation. This paper sets out to test the influences of regionalisation and psychic distance on the direction of Australian merchandise exports. The paper applies a quantitative methodology using a multiple regression model on a large, purposively compiled data set. Unlike most previous outward internationalisation studies, which use the firm as the unit of analysis, this paper uses aggregated Australian export values by country destination and export category over an extended time period, 1990 to 2004. The findings show that regionalisation is the dominant influence on the direction of Australian merchandise exports. This has important trade policy implications for Australian state and federal governments, related export promotion agencies and for managers of Australian firms, as well as for international business researchers generally.

The spatial pattern of child growth in Papua New Guinea

Child growth in PNG shows strong regional differences, with highlands children being generally shorter but stockier than those from lowland areas. Differences in diet, socioeconomic status and local subsistence agriculture were found to be important predictors of child growth. All variables indicating higher socioeconomic status were correlated with better growth, as was a high consumption of imported and local high quality foods such as cereals, legumes, tinned fish or meat and fresh fish. Differences in subsistence explained between 25% and 50% of the geographical variation in growth. Child growth was better in systems based on cassava and sweet potato, and worse in those where banana, sago and taro are staples. The cultivation of all major cash crops and sales of fish and food crops improved child growth. Birth weights show similar patterns to those observed in child growth. The implications of these findings for possible interventions are discussed.
