Duality in Dynamic Discrete Choice Models

Khai X. Chiong, Alfred Galichon, Matthew Shum
2015 Social Science Research Network  
The application of convex-analytic tools to dynamic discrete choice models, and the connection with two-sided matching models, is new in the literature.  ...  We show that the conditional choice probabilities and the choicespecific payoffs in these models are related in the sense of conjugate duality, and that the identification problem is a mass transport problem  ...  In the case when Q is a discrete distribution, the mass transport problem in the above proposition reduces to a linear-programming problem which coincides with the assignment game of Shapley and Shubik  ...

Optimal Pricing for Duopoly in Cognitive Radio Networks: Cooperate or not Cooperate?

2014 IEEE Transactions on Wireless Communications  
This strategy also requires each SU to know the average queueing delay, which is a non-trivial problem. Toward this end, we provide queueing delay analysis by using the M/G/1 queue with breakdown.  ...  From the BS's point of view, we consider a duopoly market based on the two paradigms: the opportunistic dynamic spectrum access (O-DSA) and the mixed O-DSA & dedicated dynamic spectrum access (D-DSA).  ...  ν(t + 1) with the gradient iterate (48); 3) Set t + 1 → t and go back to step 1 (until satisfying the termination criterion); between the two models: the non-cooperative and cooperative model in four  ...

Learning to disagree in a game of experimentation

Alessandro Bonatti, Johannes Hörner
2017 Journal of Economic Theory  
When actions are hidden, there exists a unique symmetric equilibrium that involves randomization over stopping times. With two players, this is the unique equilibrium.  ...  We analyze strategic experimentation in which information arrives through fully revealing, publicly observable "breakdowns."  ...  In a dynamic, continuous-time setting, we are not aware of another paper with a clear economic interpretation in which mixed strategies must be considered to ensure existence, despite convex action sets  ...

Multiplicative weights in monotropic games [article]

Ioannis Avramopoulos
2014 arXiv   pre-print
Monotropic games generalize strictly concave potential games and zero sum games with a unique minimax solution. Within the class of monotropic games, we study a multiplicative weights dynamic.  ...  We introduce a new class of population games that we call monotropic; these are games characterized by the presence of a unique globally neutrally stable Nash equilibrium.  ...  My interest in multiplicative weights grew out of a summer internship at Akamai Technologies in the summer of 2000 where I had the opportunity and privilege to work with Gary Miller and Joel Wein and interact  ...

Large Deviations and Stochastic Stability in the Small Noise Double Limit, I: Theory

William H. Sandholm, Mathias Staudigl
2014 Social Science Research Network  
The control problems are tractable in certain interesting cases, allowing analytical descriptions of the escape dynamics and long run behavior of the stochastic evolutionary process. *  ...  We show that in this double limit, escape from and transitions between equilibria can be described in terms of solutions to continuous optimal control problems.  ...  in terms of solutions to path cost minimization problems on the discrete set X N .  ...

Learning to Disagree in a Game of Experimentation

Alessandro Bonatti, Johannes Horner

When actions are hidden, there exists a unique symmetric equilibrium that involves randomization over stopping times. With two players, this is the unique equilibrium.  ...  We analyze strategic experimentation in which information arrives through fully revealing, publicly observable "breakdowns."  ...  A fortiori, the problem arises in games, and there are well-known examples of zero-sum games with sectionally convex action spaces for which the optimal policies cannot be found within the class of pure  ...

14th International Symposium on Mathematical Programming

1990 Mathematical programming  
If we use a decomposition approach in order to solve a minimization problem we often get an objective function in such a w a y that its domain dom 6 = n is not given explicitely to us.  ...  A v ariation of bundle methods is presented by means of which such a t ype of problems can be solved.In this variation a dynamic polyhedral model of dom is generated by means of normal vectors.In addition  ...  We consider examples to compare the new class of di erential games with well-known classes of games linear games with a quadratic functional and games with purely geometrical constraints and a terminal  ...

ClearPath

2009 Proceedings of the 2009 ACM SIGGRAPH/Eurographics Symposium on Computer Animation - SCA '09  
The overall approach, ClearPath, is general and can robustly handle dense scenarios with tens or hundreds of thousands of heterogeneous agents in a few milli-seconds.  ...  Our approach extends the notion of velocity obstacles from robotics and formulates the conditions for collision free navigation as a quadratic optimization problem.  ...  Acknowledgements This research is supported in part by ARO Contract W911NF-04-1-0088, NSF award 0636208, DARPA/RDECOM Contracts N61339-04-C-0043 and WR91CRB-08-C-0137, Intel, and Microsoft.  ...

A characterization of a limit solution for finite horizon bargaining problems

Haruo Imai, Hannu Salonen
2011 International Journal of Game Theory  
We investigate a two-person random proposer bargaining game with a deadline.  ...  A bounded time interval is divided into bargaining periods of equal length and we study the limit of the subgame perfect equilibrium outcomes as the number of bargaining periods goes to infinity while  ...  Coles and Wright (1998) where the game has infinite horizon, and GHM where breakdown possibility with risk preference is employed with fixed length of a period.  ...

Hybrid control synthesis for eventuality specifications using level set methods

Anastasios Trontis, Michael P. Spathopoulos
2003 International Journal of Control  
Due to the existence of set-valued disturbance inputs, the problem is studied in a game-theoretic framework.  ...  Having shown that a least restrictive solution does not exist, we propose a dynamic programming algorithm that computes the maximal initial set and a controller with the desired property.  ...  The control problem is concerned with an emergency shut-down sequence due to a cooling breakdown in the condenser.  ...

Dynamic relational contracts under complete information

Jonathan P. Thomas, Tim Worrall
2018 Journal of Economic Theory  
In the risk-averse case, the dynamics of actions and surplus may or may not be monotonic depending on whether or not a first-best allocation can be sustained.  ...  If the first-best allocation is not sustainable, there is a trade-off between risk sharing and surplus maximization; surplus may not be at its constrained maximum even in the long run and the "amnesia"  ...  In particular, we'd like to thank, Pierre Dubois, Francisco Gonzalez, Bruno Jullien and John Moore for very valuable comments. All errors are ours.  ...

The 10,000 Facets of MDP Model Checking [chapter]

Christel Baier, Holger Hermanns, Joost-Pieter Katoen
2019 Lecture Notes in Computer Science  
We survey the basic ingredients of MDP model checking and discuss its enormous developments since the seminal works by Courcoubetis and Yannakakis in the early 1990s.  ...  We discuss in particular the manifold facets of this field of research by surveying the verification of various MDP extensions, rich classes of properties, and their applications.  ...  Whereas for MDP model checking [72] , the set of achievable points is a convex area with finitely many corner points, for CTMDPs the convex area may have infinitely many corner points [135] .  ...

Measuring and hedging financial risks in dynamical world [article]

Nicole El Karoui
2003 arXiv   pre-print
History began with the paradigm of zero-risk introduced by Black & Scholes stating that any random amount to be paid in the future may be replicated by a dynamical portfolio.  ...  This challenging question has generated a deep and intensive academic research in the 20 last years, based on super-replication (perfect or with respect to confidence level) and optimization.  ...  Ill-posed inverse problem The problem of determining local volatility can be viewed as a function approximation non linear problem from a finite data set.  ...
