For application of kites to ships for power and propulsion, a scheme for predicting time averaged kite forces is required. This paper presents a method for parameterizing figure of eight shape kite trajectories and for predicting kite velocity, force and other performance characteristics....

This paper injects a time dimension into the static, instantaneous adjustment model of Stark (2004). The paper assumes that in response to the incentive conferred by the prospect of migration, the average level of human capital – the source of a productivity-enhancing externality – changes...

I argue that dynamic oligopoly models are an area of industrial organization where much work needs to be done and much work can be done. In some particular settings (e.g., network industries), dynamic oligopoly models provide sensible answers when static models fall short of doing so.

We present a dynamical model of web site growth in order to explore the effects of competition among web sites and to determine how they affect the nature of markets. We show that under general conditions, as the competition between sites increases, the model exhibits a sudden transition from a...

The consumption of milk in China has been increasing over past two decades. Currently, China does not produce enough milk to meet this increase in demand. Consequently a large volume of milk is imported. In this study, import demand for milk in China is explored using demand systems approach...

This paper estimates static Malmquist and dynamic Luenberger productivity growth measures and decomposes these to identify the contributions of technical change, technical efficiency change and scale efficiency change. The Malmquist and Luenberger productivity growth measures are estimated using...
