We develop a model of production and exchange with uncertainty concerning the quality of commodities and study the role of fiat money in ameliorating frictions caused by private information. The model is specified so that, without private information, only high-quality commodities are produced, and there is no welfare gain from using money. With private information, there can be equilibria (and sometimes multiple equilibria) where low-quality commodities are produced, and money can increase welfare. Money works by promoting useful production and exchange. In efficient monetary equilibria, agents adopt strategies that increase the probability of acquiring high-quality output.

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.
