We extend the analysis of Kiyotaki and Wright, who study economies where the commodities that serve as media of exchange (or, commodity money) are determined endogenously. Kiyotaki and Wright consider only steady-state, pure-strategy equilibria; here we allow dynamic and mixed-strategy...

Japan has seen episodes in which boom and bust in land prices is accompanied by boom and bust in business fixed investment. We develop a model that includes land in the production function. We show that in this model movements in land prices will be associated with movements of the capital stock...

There is much confusion in the economics literature on wage determination and the employment–inflation trade-off. Few model builders pay as much careful attention to the definition and meaning of long-run concepts as did Albert Ando. Expanding on years of painstaking work by Ando, the...

To analyze business fixed investment in Japan, which has been unusually volatile in recent years, we develop and apply a loglinear flexible accelerator model. We find that movements in business fixed investment are consistent with movements in output and the tax- adjusted cost of capital, both...

The authors analyze economies in which individuals specialize in consumption and production and meet randomly over time in a way that implies that trade must be bilateral and quid pro quo. Nash equilibria in trading strategies are characterized. Certain goods emerge endogenously as media of...
