Ch 25 Saving, Investment and the Financial System

*p review of financial terms learned in Micro stock market lessons

I. Saving and Investments in the National Income Accounts *assume a closed economy for now Y = C+I+G (Income = Expenditures) Subtract Consumption and Government from both sides Y-C-G = I Y-C-G : tells us our income (Y) after we paid for C and G….so this is National Savings (S) …..so Y-C-G = I ……= ……S = I *think back to AE model ….at Equilibrium, S = I …so National Savings = …. S = Y-C-G

If S = I : how is this coordinated in the economy????? THE FINANCIAL SYSTEM TAKES IN A NATION’S SAVINGS AND DIRECTS IT TO THE NATION’S INVESTMENTS (p.563)

National Savings is separated into Private and Public *must consider taxes Private Income (Y) must subtract private Taxes (T) and private Consumption ( C ) ….so Private Savings = Y-T-C Public Income consists of Tax revenue (T) and subtract Government spending (G) …so Public Savings = T-G National Savings = Private Savings + Public Savings S = ( Y-T-C) + (T-G)
