The central emphasis in the book is on the transaction and the
constraints that its architecture imposes on a discussion of monetary
theory and policy. Because of their comprehensiveness and discipline the
flow-of-funds accounts are the ideal vehicle for theorizing about real
and financial interaction. Such int- action can best be understood when
real and financial transac- tions are expressed in a common flow
dimension. Each decision by economic agents is seen as two-ended in
terms of markets: one market supplies the source of funds and the second
market absorbs these funds. A matrix of interdependent markets is
featured throughout the theoretical discussion. Credit markets, and the
bank credit market in particular, become the source of disturbance in
the theoretical model, but the necessary involve- ment of the money
market is also stressed. Theories of finan- cial instability and crisis
now receiving considerable attention are part of the more general theory
of the flow of funds. The rationale for the monetary authority to target
credit rather than the monetary aggregates emerges from the analytical
discus- sion. A flow-constrained analysis clarifies interest-rate deter-
mination, provides a helpful format for discussing equilibrium and
disequilibrium, integrates credit markets with the familiar IS-LM
framework, and identifies a class of missing equations in macro-monetary
theory. The prototype of the missing equations is an equation explaining
monetary dissaving in terms of a series of arguments only one of which
will be the stock of real balances or real wealth.
