This paper proposes an extended mobile payment service model founded on the existing ones to solve the non-repudiation problems with fair non-repudiation protocols for all phases in a typical m-commerce transaction. The novel model bases on assumptions about the cooperation between mobile network operators and financial institutions to deal with different payment amounts ranging from micro to m...

Some manufacturers impose a time-based contract on their suppliers under which each supplier is paid only when all of the suppliers have completed their tasks. We investigate whether or not the manufacturer ought to demand such a delayed payment contract. In our model with one manufacturer and two suppliers, we compare the impact of both a delayed payment regime and a no delayed payment regime ...

Two fundamental payment methods exist for online information purchase: macropayment and micro-payment. Traditional macro-payment methods, like credit and charge cards and digital currency, are suitable for large-value, low-volume transactions. However, large-volume, low-value commodities, such as discrete units of information from a website, better suit a micro-payment model. In micro-payment, ...

In this article, we construct a model to study competing payment networks, where networks offer differentiated products in terms of benefits to consumers and merchants. We study market equilibria for a variety of market structures: duopolistic competition and cartel, symmetric and asymmetric networks, and alternative assumptions about consumer preferences. We find that competition unambiguously...

The underlying model of an electronic payment system consists of three parties: a bank, a customer, and a shop. There are three different types of transactions within the system: withdrawal involving the bank and the customer, payment involving the customer and the shop, and deposit involving the shop and the bank. The customer's account is debited during withdrawal, and the shop is credited du...

Mobile technology has become increasingly common in today’s everyday life. However, mobile payment is surprisingly not among the frequently used mobile services, although technologically advanced solutions exist.

Also, implementation of an ACO is costly in terms of time and money. Immature design could cau...
