Telah dilakukan kajian model transfer uang dengan analogi transfer tenaga kinetik pada gas ideal dan model transfer uang dengan analogi penciptaan pasangan elektron positron. Pada model serupa gas ideal dapat diperoleh distribusi uang baik bila tumbukan terjadi elastik dan tidak elastik. Bila tumbukan elastik diperoleh distribusi uang serupa distribusi tenaga kinetik Boltzman-Gibbs. Bila tumbukan diasumsikan tidak elastik diperoleh distribusi uang dengan adanya kecendrungan menabung. Pada model serupa penciptaan pasangan dapat dijelaskan perpindahan aset dan liabilitas dengan bantuan diagram Feymann. Pada model ini dapat dijabarkan double entry bookkeeping.

It has been studied about money transfer model with analogy kinetic energy transfer at ideal gas and energy transfer at pair creation of electron and positron. Models ideal gas like obtained distribution of money if elastic collision and non elastic is happened. If collisions were assumed elastic, we will obtain distribution Boltzman-Gibss of money. If collision were assumed non elastic obtain distribution of money with saving propensity affects. Models pair creation-like can explanation assets and liabilities transfer through Feymann diagrams. At this models can be explained double entry bookkeeping.
