Market friction is an important factor of the study on market efficiency. The friction in physics produces entropy, and in the market model, market friction make an unstable state to generate entropy. We establish the market model and analyze this by multiple factors. Our model can effectively reflect the study results of market friction by other economists. Through the complex model, we get some results. The market friction may contribute to the optimization of local transactions. If there is no market frictions, the stock is equivalent to currency, and the sure market friction will make the consumption indifferent among different individuals. Lastly, we design some experiment models to study the friction more effectively and in depth. |
