This paper considers the costs and benefits of inflation using a stochastic version of Townsend′s turnpike model in which agents of each type are allowed to remain at a trading post for multiple periods. Numerical results show that moderate rates of inflation can be welfare-improving, but only when private credit markets are extremely limited. More generally, the existence of private credit markets curtails the ability of inflationary policy to do both harm and good. In addition, the welfare consequences of inflation depend on how much information about the economy the government has access to when implementing its policies.

This paper takes an alternative approach to the topic of money and growth by developing a model in which the effects of sustained capital accumulation on an evolving system of payments, in addition to the conventional effects of sustained inflation on growth, are examined. While the effects of inflation on growth are small, the effects of growth on the monetary system are substantial. The results are consistent with ideas about money and growth contained in work that predates that of James Tobin and Miguel Sidrauski, as well as with evidence that money and asset demands vary systematically within economies as they develop.
