We investigate this trade-off through analyzing a model that incorporates(More)
Firm-specific human capital loses its value if the firm exits the industry. This paper explores this simple but important link by developing a new firm-dynamics model that incorporates workers, their accumulation of specific human capital, and their mobility. In my model, a firm's production efficiency is determined by the levels of its managerial ability(More)
This paper explores welfare consequences of technology spillover that is accompanied by a Northern firm's FDI in the South and enhances a Southern firm's product quality. To this end, we explore an international duopoly model of vertical product differentiation in which a Northern firm (firm N) and a Southern firm (firm S) compete in the Southern market. By(More)
The statistical and soft computing methods have been used to predict time series data from different fields. The different methods have been applied on same or different time series data. One method has been selected among the applied methods based error analysis. In this paper, an algorithm has been proposed to forecast the time series data based on(More)

This paper explores oligopoly models that capture this important link between knowledge transfer and partial equity ownership (PEO). We consider an industry(More)

'Vertical keiretsu', characterized by suppliers' willingness to make customized investments and their long-term relationships with manufacturers, had been recognized as an important source of strength in Japanese industries. Our model predicts that, in contrast to the recent popular argument, the information-technology revolution can strengthen 'vertical(More)
Information about a new or non-frequently purchased product is often produced by both sides of the market. We construct a monopoly pricing model consisting of both seller's information disclosure and consumer's information acquisition. The presence of consumer search, which lowers the probability of making sales, creates incentive for the monopolist to(More)
