Banks supply payment services that underpin the smooth operation of the economy. To ensure an effi cient payment system, it is important to maintain competition among payment service providers, but data available to gauge the degree of competition are quite limited. We propose and implement a frontierbased method to assess relative competition in bank-provided payment services. Billion dollar b...

This paper studies a risk-sharing model where traders face endowment shocks and information asymmetries. We show that a negative participation externality arises due to the endogenous information aggregation by prices, and it creates a counter force to a standard positive externality of risk-sharing. As a result, the optimal market size that maximizes gains from trade per trader is finite. The ...

This is the online appendix to Frankel [48]. It consists of the omitted formal results and proofs that underlie the extensions discussed in section 3 of that paper. Section 7 studies the case of large noise; section 8 (p. 12) studies a two-period learning model; and section 9 (p. 21) studies a model of duopoly competition. In order to avoid ambiguity, numbering of sections, footnotes, and resul...

This data gives an opportunity to confi rm to some extent the degree to which these strategies are used. More importantly, perhaps, while articles on the best and worst strategies for choosing passcodes are not in short supply, the data gives us a better starting point for evaluating the entropic effi cacy of these strategies as the basis for better recommendations to end-users. And that’s a to...

Background: Aptamers are single stranded DNA (ssDNA) or RNA molecules. The potential of aptamers for binding to the different targets has made them be widely used as the preferred diagnostic and therapeutic tools. DNA aptamers present several advantages over the RNA oligonucleotides due to their higher stability, easier selection, and production. Selection of DNA aptamers which...

In an incomplete information setting, we analyze the sealed bid auction proposed by Knaster (cf. Steinhaus (1948)). This procedure was designed to effi ciently and fairly allocate multiple indivisible items when participants report their valuations truthfully. In equilibrium, players do not follow truthful bidding strategies. We find that, expost, the equilibrium allocation is still effi cient,...
