In the dynamic two-sided market environment, overpricing one side of the market not only discourages demand on that side but also discourages participation on the other side. Over time, this process can lead to a death spiral. This paper develops a dynamic structural model of the video game...

A logistic equation with delay introduced into net growth describes an initial stage of solid tumor growth. Impulses describe external interference, such as radiotherapy. Examination of different treatment protocols showed that the one with constant dosage is better than with increasing or...

I study credence goods markets when there are both selfish and conscientious experts. The selfish expert is a profit maximizer. The conscientious expert wants to maximize profit and repair the consumer's problem. There are two classes of equilibria: uniform-price equilibria and nonuniform-price...
