We build a model where introspection matters – i.e., people rationally form expectations about others using the lens of their own attitudes. Since trustworthy individuals are more “optimistic” about people than opportunists, they are less afraid to engage in market-based exchanges, where they may be vulnerable to opportunistic behavior. Within this context, we use an indirect evolutionary appro...

Given the global challenges of security, both in physical and cyber worlds, security agencies must optimize the use of their limited resources. To that end, many security agencies have begun to use "security game" algorithms, which optimally plan defender allocations, using models of adversary behavior that have originated in behavioral game theory. To advance our understanding of adversary beh...

This chapter addresses the relationship between a supplier and the manufacturers that it serves, from the perspective of transaction cost economics theory (TCE). TCE deals with relationships between organizations, such as customers, manufacturers and suppliers. It states that investment in transaction-specific assets opens the door for opportunistic behavior by an organization’s partners. Inter...

Ex-post opportunistic behavior, commonly present in bilateral trade relationships, is a key element of the transaction cost economics. Investment in outside options is a prime example of such opportunism and often leads to inefficiency, for example by exerting effort to search for alternative business partners even if it does not add trade value. We experimentally investigate a bilateral trade ...

abstract: This study is based on the theory of transaction costs (TCT) to analyze opportunistic behavior suppliers in public purchases agricultural products provided by private sector. We argue that among purchasing modalities, electronic auction, although using principles reverse English auction and considered as a market structure governance driven price, presents at time bidding seller, unti...

The current Internet design is not capable to support communications in environments characterized by very long delays and frequent network partitions. To allow devices to communicate in such environments, delay-tolerant networking solutions have been proposed by exploiting opportunistic message forwarding, with limited expectations of end-to-end connectivity and node resources. Such solutions ...

Mobility is regarded as a network transport mechanism for distributing data in many networks. However, many mobility models ignore the fact that peer nodes often carried by people and thus move in group pattern according to some kind of social relation. In this paper, we propose one mobility model based on group behavior character which derives from real movement scenario in daily life. This pa...
