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...

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...

This article develops a tractable graphical device for analyzing the stochastic overlapping generations (SOLG) economy. In this paper, the graphical device is applied to the theoretical study on stochastic bubbles per Weil [”Confidence and the real value of money in an overlapping generations...

We propose a model in which money performs an essential role in the process of exchange, despite the presence of a multilateral clearing house. Agents are assumed to be anonymous and unable to make binding commitments. The clearing house can detect deviations but it cannot identify the...

The introduction and widespread use of credit cards increases trading efficiency but, by also increasing the velocity of money, it causes inflation, in the absence of monetary intervention. If the monetary authority attempts to restore pre-credit card price levels by reducing the money supply,...

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...

We study a monetary, general equilibrium economy in which banks exist because they provide intertemporal insurance to risk-averse depositors. A quot;banking crisisquot; is defined as a case in which banks exhaust their reserve assets. Under different model specifications, the banking industry is...

In an endowment economy, we analyze coexistence and competition between traditional fiat money (Dollar) and cryptocurrency (Bitcoin). Agents can trade consumption goods in either currency or hold on to currency for speculative purposes. A central bank ensures a Dollar inflation target, while...
