the aim of this study is to carry out an empirical study of constraint factors in recreational sporting activities. more specifically it tests the model of constraints (intra-personal, interpersonal, and structural), as proposed by crawford et al. (1991), and its relationship with actual participation levels in specific recreational sports activities in iran. although there is a growing body o...

We pose and study the problem of planning in Markov decision processes (MDPs), subject to participation constraints as studied mechanism design. In this problem, a planner must work with self-interested agent on given MDP. Each action MDP provides an immediate reward (possibly different) agent. The has no control choosing actions, but option end entire process at any time. goal is find policy t...

Traditional database systems have been successful in handling large amounts of data but lack mechanisms for schema derivations and schema veriication. In this paper, we propose (i) structures that carry expressive and useful information on the database schema, (ii) a set of inference rules for schema derivations, and (iii) a mechanism for discovering contradictory schema declarations. To this e...

In incomplete information environments with transferable utility, efficient outcomes are generally implementable unless interim or ex post participation constraints are imposed on the problem. In this paper we show that linking a sufficiently large number of independent but possibly unrelated social decisions, a slightly perturbed Groves mechanism can implement an efficient outcome with probabi...

This paper builds on the existing literature on telecommunications interconnection with non-linear pricing and heterogeneous agents, by explicitly taking into account consumers’ participation decision. This single change leads to dramatically different conclusions regarding the scope for collusion by interconnecting networks.
