In spite of fiat money is useless in a standard Arrow-Debreu model, in this paper we will show that this does not hold true anymore when goods are indivisible. In our setting, although fiat money yields no utility, its price will always be positive and the set of equilibrium allocations changes...

The relationship between money and credit is discussed in terms of network linkage. Fiat money is the only instrument with the universal recognition of its issuer. Near monies such as bank money and money substitutes such as gasoline credit cards can be classified in terms of their network...

Why people accept intrinsically worthless fiat money in exchange for real goods and services has been a longstanding question. There are many competing sufficient explanations that may confound each other in practice but can be individually tested in isolation experimentally. In this paper we...

Why do people coordinate on the use of valueless pieces of paper as generally accepted money? A possible answer is that these objects have intrinsic properties that make them better candidates to be used as media of exchange. Another answer stresses the fact that unconvertible fiat money will...

This paper extends the Kiyotaki-Wright search model of fiat money to allow for divisible money and goods. The extension allows me to examine the standard issues in monetary economics, such as the neutrality and super-neutrality of money, by severing the artificial link in the Kiyotaki-Wright...

Monetarists maintain that changes in the price level are attributable to the level of the money supply. Hence, price stability has been the rationale for the money supply rule derived from the Quantity Theory of Money. Consequently, to curb inflation, the general price level index is the lever...

Conventional theory suggests that fiat money will have value in capitalpoor economies. We demonstrate that fiat money may also have value in capital-rich economies, if the price of capital is excessively volatile. Excess asset-price volatility is generated by news; information that has no social...

Closed exchange and production-and-exchange economies may have multiple equilibria, a fact that is usually ignored in macroeconomic models. Our basic argument is that default and bankruptcy laws are required to prevent strategic default, and these laws can also serve to provide the conditions...

Currency is one of the most important of social and economic institutions. Evidently, the interrelation between monetary and economic power and stability is reciprocal. A strong and stable economy facilitates the achievement and maintenance of monetary stability; conversely, monetary stability...

A series of models (kept simple in order to stress the structure of the models and the nature of the questions) are described and problems are posed pertaining to a dynamic economy with various possibilities for the issuance of fiat money, credit and insurance.
