Modeling the demand for cash and deposits is a primary concern for central banks. Within a wide range of academic contributions, payment choice models based on transaction sizes (TS models) have been promoted. However, TS models induce strong predictions about the use of payment instruments. In particular, all equal-sized transactions are supposed to be paid with the same payment instrument. We...

Drawing upon the transactional-relational continuum view of exchange, this study provides one of the very first attempts to examine the exchange relationships between individual buyers and sellers in a peer-to-peer online barter market. Using detailed transaction data and weblog data from a leading online market for book exchanges, we find that there is a dichotomy in users’ exchange orientatio...

With the rise in the availability of scalable network technologies and resources, Application Service Providers (ASPs) have become increasingly more feasible sources for obtaining IS services. ASP research represents an opportunity to integrate previous research on outsourcing, applied in the area of ASP choice. Historically, outsourcing research has adopted many theoretical perspectives, inclu...

For portfolio choice problems with proportional transaction costs, we discuss whether or not there exists a shadow price, i.e., a least favorable frictionless market extension leading to the same optimal strategy and utility. By means of an explicit counter-example, we show that shadow prices may fail to exist even in seemingly perfectly benign situations, i.e., for a log-investor trading in an...

In bitemporal databases, current facts and transaction states are modelled using a special value to represent the current time (such as a minimum or maximum timestamp or NULL). Previous studies indicate that the choice of value for now (i.e. the current time) significantly influences the efficiency of accessing bitemporal data. This paper introduces a new approach to represent now, in which cur...

We investigate how distraction affects the trading behavior of professional asset managers. Exploring detailed transaction-level data, we show that managers with a large fraction of portfolio stocks exhibiting an earnings announcement are significantly less likely to trade in other stocks, suggesting that these announcements absorb attention which is missing for the choice of which stocks to tr...

Although brokers’ trading is endemic in securities markets, the form of this trading differs between markets. Whereas in some securities markets, brokers may trade with their customers in the same transaction (simultaneous dual trading or SDT), in other markets, brokers are only allowed to trade after their customers in a separate transaction (consecutive dual trading or CDT). We show theoretic...

This paper demonstrates the relevance of consumers’ susceptibility to interpersonal influence (CSII) in an investment context. In Study 1, a survey of individual investors, investment-related knowledge, psycho-social risks, and social needs emerge as antecedents that explain investors’ susceptibility to informational and normative influence. In turn, susceptibility to normative influences incre...
