Factors Influencing the Diffusion of Electric Arc Furnace Steelmaking Technology.
Applied Economics (Impact Factor: 0.46). 02/1994; 26(9):917-25. DOI: 10.1080/00036849400000053
In this paper, the adoption of electric arc furnace steelmaking technology is examined within a growth model of technological diffusion. The results indicate that the trend rate of adoption of electric are furnace technology is well represented by the S-shaped growth curve. Further results indicate that the trend rate of adoption is, for the most part, stable with respect to locally changing factors to production, such as input prices and activity levels. It appears that inertial aspects have an overwhelming influence on the diffusion process.

- "The logistic diffusion function originated from Griliches' (1957) study for hybrid corn has been developed with other variables that allow for more flexibility within the diffusion parameter. Labson and Gooday (1994) allowed the speed of adjustment to be a linear function of observable exogenous market factors. In Gruber's (1998) study, the diffusion of innovation is also complemented with other variables that allow for more flexibility within the diffusion parameter. "
ABSTRACT: With the development of the Internet, the telecommunication market has seen a rapid shift from voice-based services to data-based services. Relationships of substitutability and complementarity have emerged among communications technology services such as Internet service, mobile phone service and fixed telephone service. The article analyses the diffusion patterns of communication services in different continents. A modified logistic growth model is estimated using panel data for the years 1975-2004. The research forms a valuable framework for forecasting demand for new services based on the diffusion of incumbent services and can inform strategies for entering the communications network industry.Applied Economics 11/2009; 41(24):3143-3150.

ABSTRACT: The world iron ore and steel trade is undergoing significant restructuring, with rapidly developing economies in regions such as China, India, and South Korea emerging as key centers of growth in the sector. Alternatively, the industrialized economies of the European Union, Japan, and North America are gradually losing their dominant role. This paper describes an econometric trade model that has been constructed to quantitatively evaluate the dynamics of the world iron ore and steel market to the year 2000. Results obtained from this model indicate that the developing Asian region will account for 67 percent of the projected increase in annual steel consumption to the end of this decade. Production in the region is projected to increase by 37.2 million tonnes. To produce this volume of steel, China alone will need to import 57.9 million tonnes of iron ore annually by the year 2000. The world's major iron ore exporters—Australia, Brazil, and India—are projected to increase production accordingly.Journal of Policy Modeling 02/1997; 19(3):237-251.
