Broadband Demand Analysis for Network Building

An increase of broadband demand is forecasted by transitional methods that consider the effect of this increase through many factors, such as customer requirement diversification, and new service introduction and deployment under competition. Broadband demand forecasting has become important for closing the digital divide, promoting regional developments, and constructing networks economically; therefore, a demand forecast model that considers the mechanisms of market structure is necessary. In this paper, a demand analysis method for broadband access combining macro- and micro-data mining is proposed, and the service choice behaviour of customers is introduced as a customer model not only to express the macro trend of market structure, but also to consider area marketing. The proposed method can estimate the potential demand, determine the point at which broadband demand growth peaks in a specified area, and support a decision for ultra high-speed broadband access facility installation.     

The Extent and Impact of Enterprise Training: The Case of Kitakyushu City

This paper examines the incidence and intensity of training as well as the impact of training on wage growth, using a unique survey of establishments and employees in Japan. We find that the worker's probability of receiving certain forms of training depends not only on union status, occupation, education, age and past job experience, but also on the business types and practices of the firms. Our evidence also suggests that formal training is associated with the measures of business growth. Controlling for such growth measures, both the incidence of routine formal training and the duration of informal training are found to boost wage increases.

Transition from School to Work in Japan

Using retrospective data of young people's work experience in Japan, this paper found that initial labor market conditions, i.e., when workers first enter the labor market after permanently leaving school, have a significant lasting impact on the employment experiences of workers in their teens and twenties. An increase in the unemployment rate at the time of labor market entry reduces the probability of gaining full-time regular employment and, more important, increases the future probability of workers of leaving employers by lowering the quality of job matches. It was also found that the vocational guidance or recommendations workers received at school could be effective in raising the quality of job matches. The adverse effect of initial unemployment rates on employment opportunities was most profoundly observed among female college graduates. J. Japan. Int. Econ., December 2001, 15(4), pp. 465–488.
