In a partially-specified correlated equilibrium (PSCE ) the players are partially informed of the conditional strategies of the other players, and they best respond to the worst-case possible strategy. We construct a decentralized procedure that converges to PSCE when the monitoring is imperfect. This procedure is based on minimizing conditional regret when players obtain noisy signals that dep...

We introduce an envelope condition method (ECM) for solving dynamic programming problems. The ECM method is simple to implement, dominates conventional value function iteration and is comparable in accuracy and cost to Carroll’s (2005) endogenous grid method.   : C6, C61, C63, C68   : Numerical dynamic programming; Value function iteration; Endogenous grid; Envelope cond...

A dynamic model with learning and adaptation captures the evolution in trader beliefs and trading strategies. Through a process of learning and observation, traders improve their understanding of the market. Traders also engage in a process of adaptation by switching between trading strategies based on past performance. The asymptotic properties are derived analytically, demonstrating that conv...

Solid state p-type dye-sensitized solar cells (p-ssDSCs) have been proposed and fabricated for the first time, using the organic dye P1 as the sensitizer on mesoporous NiO and phenyl-C61-butyric acid methyl ester (PCBM) as the electron conductor. The p-ssDSC has shown an impressive open circuit photovoltage of 620 mV. Femtosecond and nanosecond transient absorption spectroscopy has given eviden...

This paper presents a genetic algorithm to solve the orienteering problem, which is concerned with finding a path between a given set of control points, among which a start and an end point are specified, so as to maximize the total score collected subject to a prescribed distance constraint. Employing several sets of test problems from the literature, the performance of the genetic algorithm i...

We study a repeated game with asymmetric information about a dynamic state of nature. In the course of the game, the better informed player can communicate some or all of his information to the other. Our model covers costly and/or bounded communication. We characterize the set of equilibrium payoffs, and contrast these with the communication equilibrium payoffs, which by definition entail no c...

In this paper we survey recent works on rational inattention (RI) in macroeconomics within the dynamic linear-quadratic-Gaussian (LQG) setting. We first discuss how RI affects consumption smoothness and sensitivity, precautionary savings, asset pricing, portfolio choice, and aggregate fluctuations in the univariate case. We then discuss the applications of RI to macroeconomic models of permanen...

Economists model time as continuous or discrete. The recent literature on continuous time models with delays should help to bridge the gap between these two families of models. In this note, we propose a simple time–to–build model in continuous time, and show that a discrete time version is a true representation of the continuous time problem under some sufficient conditions. JEL codes: O40, E3...
