We measure the United States capital stock of money implied by the Divisia monetary aggregate service flow, in a manner consistent with the present-value model of economic capital stock and asset pricing theory. The resulting measures differ substantially from the usual simple sum accounting monetary aggregates. We permit non-martingale expectations and time varying discount rates. Based on Bar...
