We address the issue of manipulating games through communication. In the specific setting we consider (a variation of Boolean games), we assume there is some set of environment variables, the value of which is not directly accessible to players; each player has their own beliefs about these variables, and makes decisions about what actions to perform based on these beliefs. The communication we...

The fundamental aim in fisheries management is to determine an optimal fishing effort for sustainably harvesting from a replenishable resource. The current management objective of Australia’s Northern Prawn Fishery is to maximize the long-term net economic return following Australian government policy, resulting in an average recent catch of tiger prawn species of about 1,250 tons only. However...

F F Abstract—This paper analyzes the buyback contract of a supply chain including one retailer, one distributor and one supplier in a fuzzy decision making environment. The market demand is characterized as a fuzzy variable. To defuzzify the fuzzy number into a crisp one, the weighted possibilistic mean value method is applied, and the risk attitudes of the supply chain members are also conside...

Financial markets are overwhelmed by daily announcements. We use experimental asset markets to assess the impact of releasing public messages with different levels of reliability on asset prices. Subjects receive qualitative announcements in predetermined trading periods that are either preset by the experimenter, randomly selected, or determined by past asset market prices. We find that messag...

This paper investigates the role of scheduled news announcements in explaining the transmission of volatility, both within European markets and across U.S. and European ones. To this end, a novel approach is taken by employing a set of widely followed implied volatility indices. Aggregate, regional, and individual event dummies and surprise measures for U.S. and European news announcements are ...

The Vanderbilt University Center for Science Outreach (CSO) connects university scientists to the K-12 community to enhance and improve science education. The Virtual Scientist program utilizes interactive videoconference (IVC) to facilitate this connection, providing 40-50 sessions per academic year to a national audience. Scientists, defined as research faculty members, clinicians, postdoctor...

In this paper, we explore the impact of delay announcements using an empirical approach by analyzing the data from a medium-sized call center. We first explore the question of whether delay announcements impact customers’ behavior using a nonparametric approach. The answer to this question appears to be ambiguous. We thus turn to investigate the fundamental mechanism by which delay announcement...

There is general agreement that many, if not most, fisheries subsidies are detrimental to effective resource management. There is not, however, general agreement about subsidies used for decommissioning/buyback purposes. One school of thought argues that such subsidies can have a positive impact upon resource management, by removing excess fleet capacity from the fisheries. An opposing school o...

In the matroid buyback problem, an algorithm observes a sequence of bids and must decide whether to accept each bid at the moment it arrives, subject to a matroid constraint on the set of accepted bids. Decisions to reject bids are irrevocable, whereas decisions to accept bids may be canceled at a cost which is a fixed fraction of the bid value. We present a new randomized algorithm for this pr...
