We develop a random-matching model to study the price dynamics of monies produced privately according to a time-consuming mining technology. For our leading example, there exists a unique equilibrium where the value of money increases over time and reaches a steady state. There is also a continuum of perfect-foresight equilibria where the price of money inflates and bursts gradually over time. Initially, money is held for a speculative motive, but it acquires a transactional role as it becomes sufficiently abundant. We study fiat, commodity, and crypto monies, endogenous acceptability, and adopt implementation and equilibrium approaches. (JEL E31, E42, E51, N13, N14, N23, N24)
期刊介绍:
American Economic Journal: Macroeconomics focuses on studies of aggregate fluctuations and growth, and the role of policy in that context. Such studies often borrow from and interact with research in other fields, such as monetary theory, industrial organization, finance, labor economics, political economy, public finance, international economics, and development economics. To the extent that they make a contribution to macroeconomics, papers in these fields are also welcome.
