Unpredictable behavior is central to optimal play in many strategic situations because predictable patterns leave players vulnerable to exploitation. A theory of unpredictable behavior based on differential complexity constraints is presented in the context of repeated two-person zero-sum games....

This paper adopts mechanism design to investigate the coexistence of fiat money and higher-return assets. We consider an economy with pairwise meetings where fiat money and risk-free capital compete as means of payment, as in [28]. The trading mechanism in pairwise meetings is chosen among all...

The Lagos-Wright model -- a monetary model in which pairwise meetings alternate in time with a centralized meeting -- has been extensively analyzed, but always using particular trading protocols. Here, trading protocols are replaced by two alternative notions of implementability: one that allows...

The Lagos-Wright model-a monetary model in which pairwise meetings alternate in time with a centralized meeting-has been extensively analyzed, but always using particular trading protocols. Here, trading protocols are replaced by two alternative notions of implementability: one that allows only...

We present an axiomatization of expected utility from the frequentist perspective. It starts with a preference relation on the set of infinite sequences with limit relative frequencies. We consider three axioms parallel to the ones for the von Neumann–Morgenstern (vN–M) expected utility...

Existing solutions to the problem of coexistence of money and higher-return substitutes that rely on imperfect recognizability of the substitutes adopt extreme assumptions: they either have a zero cost of counterfeiting the substitutes or omit plausible refinements that would rule out pooling...
