We analyze wealth condensation for a wide class of stochastic economy models on the basis of the economic analog of thermodynamic potentials, termed transfer potentials. The economy model is based on three common transfers modes of wealth: random transfer, profit proportional to wealth and...

We analyze a monetary system of random money transfer on the basis of double entry bookkeeping. Without boundary conditions, we do not reach a price equilibrium and violate text-book formulas of economists quantity theory (MV=PQ). To match the resulting quantity of money with the model...

Although economic practice is measured by bookkeeping, economic theory neglects its role. We want to bridge this gap. We analyze the structure of bookkeeping from a mechanical viewpoint and compare money with momentum. Bookkeeping and income statements translate to the physicist vocabulary of...
