Circuit theory of banking and finance

Drawing on monetary circuit theory, this study develops an approach to analyze the integrated functions of banking and finance in a monetary production economy. The study proposes a micro-founded, circuit-sequenced model of a decentralized-decisions economy, where production, exchange, and investment from households and firms are integrated through money creation and funds allocation operated, respectively, by banks and non-bank financial intermediaries. The model is used to draw implications on: the special nature of banks and the role of non-bank financial intermediaries; the relationship between saving and investment; and the channels through which finance may cause the circuit process to break down. The study also discusses how the circuit approach can be used for an integrated analysis of economic and financial structural change.
