The growth of open networks created the interest to commercialise it. The establishment of an electronic business mechanism must be accompanied by a digital – electronic payment system to transfer the value of transactions. Financial organizations are requested to offer a secure e-payment synthesis with equivalent level of security served in conventional paper-based payment transactions. PKI, w...

In games where agents are asked to declare their available resources, they can also strategize over this declaration. Surprisingly, not in all such games a VCG payment can be applied to construct a truthful mechanism using an optimal algorithm, though such payments can prevent under-reporting of resources. We show this for the problem of allocating tasks in a social network (STAP). Since STAP i...

Background: This paper is an effort to analyze cashless payment vs Conventional system in India. The current study focuses on the challenges and threats faced by Indian consumer while using digital money. highlights buying patter of context conventional system. Methods: In theoretical model constructed reviewing different journals based as well evaluates factor effecting purchase decision light...

The buyer’s type is his value  ∈ [ ] and the seller’s type is his cost  ∈ [ ]. The buyer’s value is drawn from a distribution (·) whose density (·) is nonzero on [ ], while the seller’s cost is drawn from the distribution  (·) whose density (·) is nonzero on [ ]. A trader observes his own type but not the type of the other trader. The buyer’s ex post utility from acquiring the...

Over the last decade, Africa has become a global leader in mobile money—cashless electronic payment that use mobile telephones as the main payment mechanism, rather than using a smartphone only as a conduit to a user’s bank or credit card account. More than half the mobile money companies in the world operate in Africa. In 2014, the most recent year for which figures are available, the mobile m...

Today, charging of EVs generally takes place at home. Just a few charging stations are available in public areas – as part of model studies. Since vehicles are parked frequently, e.g. while shopping or at work, they can be charged during these times. In the future, a broadly based and standardized infrastructure will be built up for this purpose. It has to offer a standardized mechanism for cha...

We propose a hybrid auction mechanism for sponsored search, where bidders can be truthful or not, and are accordingly treated differently. Our class of hybrid mechanisms give incentives for non-truthful bidders to bid truthfully, while behaving as a non-truthful auction if no bidders are truthful. Our motivation is that the Generalized Second Price (GSP) auction (the current mechanism of choice...

The Generalized Second Price (GSP) auction has appealing properties when ads are simple (text based and identical in size), but does not generalize to richer ad settings, whereas truthful mechanisms such as VCG do. However, a straight switch from GSP to VCG incurs significant revenue loss for the search engine. We introduce a transitional mechanism which encourages advertisers to update their b...

We model asymmetric information arising from physician agency, and its effect on the design of payment and health care quantity. The physician-patient coalition aims to maximize a combination of physician profit and patient benefit. The degree of substitution between profit and patient benefit in the physician-patient coalition is the physician’s private information, as is the patient’s intrins...

In the space of designs by which to auction off a single good, we have seen that there is a significant difference between a payment scheme that charges the second-highest bid, and one in which bidders pay their bids. In this lecture, we introduce a new payment and allocation scheme, called the posted-price mechanism, in which the auctioneer announces (i.e., posts) the price π at which they are...
