Internal switches in all-photonic networks do not perform data conversion into the electronic domain, thereby eliminating a potential capacity bottleneck, but they introduce network scheduling challenges. In this paper we focus on scheduling fixed-length frames in all-photonic star-topology networks. We describe the Fair Matching (FMA) and Equal Share (ESA) algorithms, novel scheduling procedur...

A characterization of “generalized Bayesian updating” in a maxmin expected utility setting is provided. The key axioms are consequentialism and constant-act dynamic consistency. The latter requires that, if an arbitrary act f is preferred (inferior) to a constant act y conditional upon E, and if f dominates (is dominated by) y pointwise on the complementary event E, then f is unconditionally pr...

In this paper we argue that a large class of recursive contracts can be studied by means the conventional Negishi method. A planner is responsible for prescribing current actions along with distribution future utility values to all agents, so as maximize their weighted sum utilities. Under convexity method yields exact efficient frontier. Otherwise implementation re- quires contingent on public...

A seller chooses a reserve price in second-price auction to maximize worst-case expected revenue when she knows only the mean of value distribution and an upper bound on either values themselves or variance. Values are private iid. Using indirect technique, we prove that it is always optimal set seller's own valuation. However, maxmin may not be unique. Sometimes choose deterministic even rando...

A multiple-input single-output cognitive radio downlink network is studied with simultaneous wireless information and power transfer. In this network, a secondary user coexists with multiple primary users and multiple energy harvesting receivers. In order to guarantee secure communication and energy harvesting, the problem of robust secure artificial noiseaided beamforming and power splitting d...

A study of fairness in multicast networks poses several interesting problems e.g., the issue of intra-session fairness in addition to that of inter-session fairness in unicast networks. We develop a mathem...

Dynamic models of ambiguity aversion are increasingly popular in applied work. This paper shows that there is a strong interdependence in such models between the ambiguity attitude and the preference for the timing of the resolution of uncertainty, as defined by the classic work of Kreps and Porteus (1978). The modeling choices made in the domain of ambiguity aversion influence the set of model...

We consider a market model with n rational firms (doctors) and a continuum of boundedly rational consumers (patients). Following Spiegler (2006a), we assume that patients are not familiar with the market and rely on anecdotes. We analyze the price setting game played by doctors with given, different healing qualities. Doctors know their own quality, as well as the qualities of their competitors...
