In this paper I investigate the nature of the beliefs which agents must hold (at least implicitly) in order to justify their considering various alternatives, in two distinct settings: the Walrasian model without production (with competitive equilibrium), and the sell-all version of the...

This paper investigates the existence of unique equilibrium in two-good economies where agents have preferences with the same relative risk aversion and different utility weights. Aggregate demand behavior is characterized in terms of both macrolevel and micro-level information inherent in the...

This paper addresses firstly why people have to use fiat money and then why they are rationally willing to accept it from the perspective of general equilibrium by using dynamic game to determine agents' expectation of its purchasing power in unrevealed future. Its model formulates the process...

In an infinite-time decentralized sequence economy, agents use fiat money to bridge markets as if they make trades in a centralized economy, to avoid huge transaction cost that all agents' going together must incur. The model in this paper formulates the process how agents decide the fiat...

The paper presents and studies a new concept of coalition domination for incomplete markets. It was elaborated applying a contractual approach and based on the notion of fuzzy contractual allocation, see Marakulin (2011, 2013). Core allocations are implemented by the net trades (webs of...

We show that all the fundamental properties of competitive equilibrium in Marshall's theory of value, as presented in Note XXI of the mathematical appendix to his Principles of Economics (1890), derive from the Strong Law of Demand. This is, existence, uniqueness, optimality, global stability of...

We study the design of mechanisms that implement Lindahl or Walrasian allocations and whose Nash equilibria are dynamically stable for a wide class of adaptive dynamics. We argue that supermodularity is not a desirable stability criterion in this mechanism design context, focusing instead on...

We present a new notion of cardinal revealed preference that exploits the expenditure information in classical consumer theory environments with finite data. We propose a new behavioral axiom, Acyclic Enticement (AE), that requires the acyclicity of the cardinal revealed-preference relation. AE...

Taxation under oligopoly is analysed in a general equilibrium setting where the firms are large relative to the size of the economy and maximise the utility of their shareholders. It turns out that the model is an aggregative game, which simplifies the comparative statics for the effects of...
