Q

Real GDP

141
Increase in government spending leads to
Increased government spending is likely to cause a rise in aggregate demand (AD). This can lead to higher growth in the short-term. It can also potentially lead to inflation
142
A decrease in government taxation leads to
lowering taxes raises disposable income, allowing the consumer to spend additional sums, thereby increasing GNP. (gross national product)

182
Four sectors of the economy
Government, households,firms and rest of word
183
Households breakdown
ncome through factor markets (wage from working, interests from capital etc.) →Households own factors of production (labor, land, physical capital, human capital, financial capital) and sell the use of these to firms. Pay taxes: income –taxes : disposable income Disposable income is spent on consumption, what is left are personal savings. Personal savings are invested via financial markets (banks, stocks, etc.)
184
Government breakdown
Has income through taxation and borrowing, spends by buying goods and services and through government transfers
185
Firms breakdown
Are financed through financial markets By inputs from factor markets engage in investment spending
186
Rest of the world breakdown
A ountry is not closed our isolated. Goods and services are exported or imported. Countries can borrow and lend
187
alternative ways of calculating gdp
Look at what has been spent on acquiring (domestically produced) total goods and services. Adding up total factor income earned by households from firms in the economy.

192
Inflation has economic costs because of unit of account (definition)
it may become increasingly hard to use the currency as a unit of account and makes various economic decisions less efficient, harder
193
If inflation is high who benefits who loses
So if inflation is higher than expected, those who lend out lose and those who borrowed gain!
194

198
Savings–investment spending identity
savings and investment spending are always equal for the economy as a whole
199
Savings (gov) formula
T − TR − G • T = the value of tax revenues, TR = the value of government transfers, G = the value of government spending

205
An increase for demand for loanable funds creates:
A rise in the equillibrium interest rate
206
Global loanable funds market
arises when international capital flows are so large | that they equalize interest rates across countries.
207
What changes the interest rate
Anything that shifts either the supply of loanable funds curve or the demand for loanable funds curve changes the interest rate.
208
Three tasks of a financial system

the relationship for the economy as a whole between aggregate disposable income and aggregate consumer spending c = a + MPC × yd
214
what tends to drive the booms and busts in the business cycle.
Investment spending
215
Two possible sources of a shift of planned aggregate spending line
Change in interest rate or wealth
216
The aggregate demand curve shifts because of
expectations. • wealth. • size of the existing stock of physical capital. • government policies. Increase in aggregate demand shifts the curve to the right
217

223
Reserve ratio formula
the fraction of bank deposits that a bank holds as | reserves ($100,000/$1,000,000 = 10%)
224
If the Fed wants to increase money supply it will
buy T bills to pay for the T-bills, Fed electronically increases the reserves of the seller • with more reserves, banks increase loans • money supply increases as the loans/money creation process ripples through the economy
225
If the Fed wants to decrease money supply they will
Sell T bills • in exchange for the T-bills, Fed decreases the reserves of the seller • with fewer reserves, banks decrease loans • money supply decreases as the loans/money creation process ripples through the economy in reverse
226
