Hairy Heel Warts: Fads and Fashions

Lameness is an economically important problem in dairy cattle worldwide. Economic losses resulting from lameness arise not only from the cost to treat clinical cases but also from decreased milk production, decreased reproductive efficiency and premature culling. New York researchers estimate the total cost of lameness per 100 cows per year to be nearly $9000. The average incidence was 30 cases...

Management Techniques : Transient Fads or Trending Fashions ?

A model of fads, fashions, and group formation

I develop a model of consumer behavior where agents purchase goods in order to signify personal characteristics. Agents purchase goods in order to imitate agents similar to them and agents they want to emulate. Depending on parameter values of consumer preferences the model generates stable groups, fads and fashion cycles, or a mixture of both. The model is unique to the economic literature on ...

The Effect of Selection Bias in Studies of Fads and Fashions

Most studies of fashion and fads focus on objects and practices that once were popular. We argue that limiting the sample to such trajectories generates a selection bias that obscures the underlying process and generates biased estimates. Through simulations and the analysis of a data set that has previously not been used to analyze the rise and fall of cultural practices, the New York Times te...

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
