We develop and test a model of initial play for symmetric normal-form games with multiple Nash equilibria. First, we specify an encompassing model that incorporates both equilibrium selection principles and boundedly rational behavioral models. We then design experimental games that can identify a variety of equilibrium selection principles. Model comparisons and hypothesis tests indicate that:...

One problem caused by cycles of choice functions is indecisiveness—decision makers will be paralyzed when they face choice sets with more than two options. We investigate the procedure of “random sampling” where the alternatives are random variables. When comparing any two alternatives, the decision maker samples each of the alternatives once and ranks them according to the comparison between t...

Jump bidding is a commonly observed phenomenon that involves bidders in ascending auctions submitting bids higher than required by the auctioneer. Such behavior is typically explained as due to irrationality or to bidders signaling their value. We present field data that suggests such explanations are unsatisfactory and construct an alternative model in which jump bidding occurs due to strategi...

In this paper we present a new technique for sparse matrix multiplication on vector multiprocessors based on the efficient implementation of a segmented sum operation. We describe how the segmented sum can be implemented on vector multiprocessors such that it both fully vectorizes within each processor and parallelizes across processors. Because of our method’s insensitivity to relative row siz...

Netupitant is a new, selective NK1 receptor antagonist under development for the prevention of chemotherapy-induced nausea and vomiting. Two studies were conducted to evaluate the brain receptor occupancy (RO) and disposition (ADME) of netupitant in humans. Positron emission tomography (PET) imaging with the NK1 receptor-binding-selective tracer [(11) C]-GR205171 was used to evaluate the brain ...

In this study, compressive strength, density, porosity, and methylene blue adsorptive intensity of sodium aluminosilicate monolith produced from coal fly ash (CFA), ceramic tile waste (CTW), spent bleaching earth (SBE) were evaluated. Using simple lattice mixture design, CFA-CTW-SBE blend with mass ratio 55.95% CFA, 38.73% CTW, 5.31% SBE, an alkali solution containing 80% 8M NaOH 20% silicate, ...

We introduce a set-valued solution concept, M equilibrium, to capture empirical regularities from over half century of game theory experiments. show equilibrium serves as meta for various models that hitherto were considered unrelated. is empirically robust and, despite being set-valued, falsifiable. Results series experiments compare leading behavioral demonstrate its virtues in predicting obs...

A discrete public good is provided when total contributions exceed the contribution threshold. I show that for a large class of threshold probability distributions, an increase in threshold uncertainty by 2nd-order stochastic dominance will increase (decrease) equilibrium contributions when the public good value is su ciently high (low). In an experiment designed to test these predictions, beha...

This paper studies lying. An agent randomly picks a number from a known distribution. She can then report any number and receive a monetary payoff based only on her report. The paper presents a model of lying costs that generates hypotheses regarding behavior. In an experiment, we find that the highest fraction of lies is from reporting the maximal outcome, but some participants do not make the...

Expectations play a crucial role in modern macroeconomic models. We consider a New Keynesian framework under rational expectations and under a behavioral model of expectation formation. We show how the economy behaves in the alternative scenarios with a focus on inflation volatility. Contrary to the rational model, the behavioral model predicts that inflation volatility can be lowered if the ce...
