Classes of economies with consumption externalities and decisive, nonwasteful, and informationally decentralized allocation mechanisms on classes including these classes of economies are constructed. The informational size of the message spaces is shown to be minimal among the message spaces...

We consider a discrete time, pure exchange infinite horizon economy with $ n\geq 2$ consumers and $\ell \geq 1$ consumption goods per period. Within the framework of decentralized mechanisms, we show that for any given consumption trade at any period of time, say at time one, the consumers will...

We consider a discrete time, pure exchange infinite horizon economy with two or more consumers and at least one concumption good per period. Within the framework of decentralized mechanisms, we show that for a given consumption trade at any period of time, say at time one, the consumers will...
