A client has a problem, but does not know whether it is serious or minor. She consults an expert who can correctly diagnose and fix her problem. This paper characterizes the equilibrium pricing and recommendation strategies of an expert under the assumptions that i) the type of treatment is...

We study delegating a consumer's treatment plan decisions to an altruistic physician. The physician's degree of altruism is his private information. The consumer's illness severity will be learned by the physician, and also become his private information. Treatments are discrete choices, and can...

A decision maker offers a new product to a number of potential adopers. He does not know the value of the product, but adopers receive some private information about it. We study how the decision maker may influence learning among adopers by manipulaing the launch sequence when both the decision...

The present longitudinal study examined life satisfaction and the related socio-demographic, family, and positive youth development correlates in junior secondary school students in Hong Kong. Results showed that adolescents perceived life satisfaction decreased in their junior secondary school...

A monopolist launches a new product to distinct markets. The monopolist does not know the quality of the product while consumers in each market receive some private information about the quality. We study how the monopolist may in°uence consumer learning by manipulating the launching sequence...

False data injection (FDI) is considered to be one of the most dangerous cyber-attacks in smart grids, as it may lead to energy theft from end users, false dispatch in the distribution process, and device breakdown during power generation. In this paper, a novel kind of FDI attack, named...

In China and some other developing countries' public health sectors, many patients give their doctors a payment outside the official channel before a major treatment. This secret payment has been documented as informal payment in the literature. We argue that the fundamental cause for informal...

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...
