In the Basic Circular Flow O = Y = E Where: O = output (production) Y = income E = expenditure (demand) Copyright 2005 Mc. Graw-Hill Australia Pty Ltd PPT Slides t/a Economics for Business 3 e by Fraser, Gionea and Fraser 15 -5
The Financial Sector • Saving (S) = Part of the Income that is not spent (leakage) • Total income = consumption spending + saving, i. e. Y=C+S • Investment (I) = that part of production that is not used for current consumption, e. g. capital goods Total income (Y) = C + I • Investment is an injection. If: S > I, the economy contracts S < I, the economy expands S = I, the economy is in equilibrium • The financial sector acts as an intermediary between lenders and borrowers Copyright 2005 Mc.

The Government Sector • Government taxation (T) reduces households’ disposable income and business funds Taxation (T) is a leakage (outflow) • Government spending (G) includes expenditure on collective goods and services and goods and services provided by the business sector, plus transfer payments (social security payments) Copyright 2005 Mc.

The Open Economy • Total leakages (outflows) are S, T and M • Total injections are I, G and X • The impact of total leakages/injections on the economic activity is as follows: S + T + M = I + G + X equilibrium S + T + M > I + G + X contraction S + T + M < I + G + X expansion Copyright 2005 Mc.
