We build a one-period general equilibrium model with money. Equilibrium exists, and fiat money has positive value, as long as the ratio of outside money to inside money is less than the gains to trade available at autarky. We show that the nominal effects of government fiscal and monetary policy...

This study derives the monetary structure of transactions, the use of commodity or fiat money, endogenously from transaction costs in a segmented market general equilibrium model. Market segmentation means there are separate budget constraints for each transaction: Budgets balance in each...

In this paper, we articulate a vision for how widespread adoption of Digital Fiat Currency may affect the macroeconomic levers a nation has at its disposal to steady economic growth. We describe monetary (and certain fiscal) policy implications of a nation's choice to incorporate Digital Fiat...

This paper reviews what cryptocurrencies are, and it frames them within the context of historical monetary experiences and contemporary monetary economics. The paper argues that, as pure duciary private money, cryptocurrencies are a bubble without a fundamental value and that they will not...

This paper mainly addresses why people are rationally willing to cooperate with one another to accept fiat money from the perspective of decentralized sequential general equilibrium framework by using dynamic game to determine agents' expectation of nominal prices in unrevealed future. The model...

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...

Kiyotaki-Wright (1991, 1993) ensured fiat money's essentiality; but they abstract competition away. Therefore, Lagos-Wright (2005) added a frictionless centralized market to their model; however, their method should be improved. This paper directly substitutes perfectly competitive decentralized...
