All my research projects start with fundamental questions about money. Why does it exist at all? Why does it exist in the form that it does? Where do new forms come from and why? What are the roles of markets versus governments in affecting the answers to these questions?

As the projects progress they often lead to lessons in various fields: theory, history, macroeconomics, and political economy. The projects are arranged below according to these fields.

In terms of methodology, anything goes. I started with mathematical models, turned to historical legal narrative, and in yet unpublished or unfinished work I have used econometrics, laboratory experiments, and computerized models. The topic, however, is always the same: why money?
