Transaction costs are one of the major impediments to the implementation of dynamic hedging strategies. We consider an alternative to utility maximization, similar to the “good-deal” pricing framework in incomplete markets. We perform a dynamic riskreward analysis for a family of non-self-financing strategies of practical importance: deterministic time hedging; i.e., hedging at predetermined, f...

Therein, a sound understanding of transaction costs of respective payment instruments is extremely relevant when deciding which payment method to offer in ecommerce. Using a unique dataset with more than 14 million actual sales transactions from a leading ...

Multi-period guarantees are often embedded in life insurance contracts. In this paper we consider the problem of hedging these multiperiod guarantees in the presence of transaction costs. We derive the hedging strategies for the cheapest hedge portfolio for a multi-period guarantee that with certainty makes the insurance company able to meet the obligations from the insurance policies it has is...

We present a cryptographic protocol for securing electronic commerce over the Internet. The protocol reeects existing transaction models in two respects: (1) it uses only traditional parties to complete a nancial transaction and so the transaction cost is kept low; and (2) it preserves some important features of the conventional transaction systems, which have been the key elements for the conv...

Theory suggests that when transaction costs are low, corporations and stakeholders can minimize social costs by transacting to their mutual advantage, but when transaction costs are high, reducing social costs requires the intervention of a centralized institution. In surprisingly little work have scholars considered what happens in between—when transaction costs exist but recourse to hierarchi...
