The money exchanger model adjust exchange rates such as to create incentives towards trade equilibrium, consistent with the classical arguments of Hume. When trade takes pleace between nations, the importer takes from the exchanger the importer's money for the goods delivered. As a result, the money exchange system will hold more of the importer's money and less of the exporter's , giving rise to adjustment of the exchange rate in the exporting nation,s favor. Thus, if money exchange system initially held 10 million and 5 bath, for an exchange rate of 2 to 1 bath, the export of 2 million dollars worth of products by Nation A to Nation B causes the system to disburse 2 million to exporter and receive 1 bath from importer, resulting in a new exchange rate of about 1.3 to 1.
