General equilibrium is investigated with N commodities traded at N(N-1)/2 commodity-pairwise trading posts. Trade is a resource-using activity recovering transactions costs through the spread between bid (wholesale) and ask (retail)prices (quoted as commodity rates of exchange). Budget...

Existence and efficiency of general equilibrium with commodity money is investigated in an economy where N commodities are traded at N(N-1)/2 commodity-pairwise trading posts. Trade is a resource-using activity recovering transaction costs through the spread between bid (wholesale) and ask...

Walrasian general competitive equilibrium is considered in a simple example of an exchange economy with commodity-pairwise trading posts and transaction costs. Budget balance is enforced at each trading post separately. Commodity-denominated bid and ask prices at each post allow the post to...

In an economy with commodity-pairwise trading posts and transaction costs, commodity money is endogenously determined in general equilibrium. Absent double coincidence of wants, the low-transaction cost commodity (with the narrowest proportional bid/ask price spread) becomes the common medium of...

General equilibrium is investigated with N commodities traded at N(N−1) 2 commodity-pairwise trading posts. Trade is a resource-using activity recovering transaction costs through the spread between bid (wholesale) and ask (retail) prices (quoted as commodity rates of exchange). Budget...

General equilibrium is investigated with N commodities traded at N(N − 1)/2 commodity-pairwise trading posts. Bid and ask prices are quoted as commodity rates of exchange. Trade is a resource-using activity undertaken by firms recovering transaction costs through the spread between bid...

In the classic Arrow-Debreu model, the existence of money is not accommodated. However, using trading post market segmentation and requiring budget balance in each pair-wise transaction the model can converge to monetary equilibrium. Uniqueness of the common medium of exchange (commodity money)...
