A model of banking and means of payment is constructed to analyze the effects of the introduction of central bank digital currency (CBDC). That CBDC is interest bearing is not an advantage, as replacement of physical currency with CBDC does not expand the attainable set of equilibrium allocations. CBDC can increase welfare by competing with private means of payment and shifting safe assets from the private banking sector to what is effectively a narrow banking facility. This uses the aggregate stock of safe collateral more efficiently, given incentive problems in private banking.

The late nineteenth century saw international mass migrations of capital and labor from the Old World to the New. Factors chased each other and the abundant resources at the frontier. Demographic structure also contributed to the massive capital flows from Britain to the New World. The dependency hypothesis is confirmed by estimation of savings functions in three New World economies (Argentina, Australia, and Canada) in which high dependency rates may have significantly depressed domestic savings rates and pulled in foreign investment: in effect an intergenerational transfer from old savers in the Old World to young savers in the New.

The last two decades have clearly shown that increased automobile ownership and highway construction can facilitate profound redistributions of population and economic activity within metropolitan areas. These changes are related in a fundamental way to many of the social and economic difficulties of our large, mature, central cities: loss of middle and upper income groups to the suburbs, declining retail sales in downtown areas, erosion of the tax base, shift of manufacturing and service establishments to suburban areas, decline of mass transit service and patronage, and increased traffic congestion. There is a great deal of support for the view that there has been too much highway construction and that the time has come to help public transportation. This paper explores some of the issues involved in a program of assistance to public transportation.

In this paper, a general-equilibrium business- cycle model is construct ed that, when subjected to real disturbances, mimics observed qualita tive comovements among real output, money, business failures, risk pr emia, intermediary loans, and prices. In contrast, monetary disturban ces generate cycles that have several inconsistencies with empirical evidence, thus providing support for real business-cycle theory at th e expense of monetary theories of the business cycle. Financial inter mediation arises endogenously in the model and intermediation matters for business-cycle behavior. A credit supply mechanism acts in tande m with an intertemporal substitution effect in propagating stochastic disturbances.
