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 paper provides a non-steady state general equilibrium foundation for the transactions demand for money going back to Baumol (1952) and Tobin (1956). In our economy, money competes against real capital as a store of value. We prove existence of a monetary general equilibrium in which both...

This paper aims to integrate the money market into the structure of the economy. The microfoundation is the starting point to define the money market and the general equilibrium mechanism of the economy. On this basis, this research seeks a linking mechanism of the money market with economic...

We study money creation and destruction in today’s monetary architecture within a general equilibrium setting. Two types of money are created and destructed: bank deposits, when banks grant loans to firms or to other banks, and central bank money, when the central bank grants loans to private...

Monetary and fiscal policy do not determine the stochastic path of prices: in the absence of financial policy, there remains indeterminacy indexed by an arbitrary probability measure over the set of states of the world. With an interest rate policy, and only if the asset market is complete,...

We consider a cash-in-advance economy under uncertainty in which monetary policy sets either short-term nominal interest rates or money supplies. We show that both the initial price level and the distribution of the inflation rate up to its expectation are indeterminate, regardless of the degree...

Money provides liquidity services through a cash-in-advance constraint. The exchange of commodities and assets extends over an infinite horizon under uncertainty and a complete asset market. Monetary policy sets the path of rates of interest and accommodates the demand for balances. Competitive...

In this paper we study the impact of the degree of concentration of a financial system on the aggregate demand for housing as well as the feedback effect of the size of the mortgage loan market on lenders' profits, internal capital accumulation, loan losses and potential bailouts. In a general...

Standard economics starts with behavioral axioms and arrives at conclusions about the equilibrium properties of the economy as a whole at point t. The present paper employs objective structural axioms and random changes in order to determine the conditions for market clearing and budget...
