The description of the dynamics and fluctuations of macro variables remains one of the most exciting problems of financial economics. This paper models macro variables via the description of transactions between agents. We use risk ratings x of agents as their coordinates in the economic space....

This paper presents macro-finance as ensemble of economic agents and suggests use risk ratings of economic agents as their coordinates on economic space. Financial variables of separate economic agents are defined as functions of time and coordinates on economic space. Aggregations of financial...

This paper develops parallels between economics and physics and describes macroeconomics as multi-agent systems on economic space alike to multi-particle systems. Economic agents play roles of simple units of macroeconomics alike to “economic particles” and agent's risk ratings define their...

This paper models macro-finance on economic space alike to description of multi-particle systems. We treat economic agents as simple units of macro-finance system and use their risk ratings as their coordinates on economic space. Financial variables of separate economic agents are defined as...
