Short Run Effects of Expansionary Fiscal Policy
When nominal GDP increases, Money supply increases (money demand curve shifts RIGHT, even tho supply is same) --> higher nominal interest rate (i), leads to crowding out
Recessionary Gap
Y actual < Y Potential Price Level decreases Unemployment ABOVE natural rate
Inflationary Gap
Y actual > Y Potential Price Level increases Unemployment BELOW natural rate
Productivity
Y/L --> (GDP/ Number of labor hours)
Disposable income (Y^D)
Y^D = (Y - T) + TR (Y-T) = total taxes TR = total returns
Crowding out
nominal interest rate (i) increases --> real interest rate (r) increases --> C, I, NX decreases --> AD decreases/ shifts LEFT (sorta)
Per Capita GDP
per capita GDP = GDP/ population
Cyclical Unemployment
ppl are looking for jobs but no one is hiring, aka Recession
Consumption Function
the relationship between consumption spending and disposable income
Absolute convergence
two factors of tech transfer and poor countries attracting more capital ALONE will allow countries to converge
Domestic Financial Account
what foreign country buys from us - What we buy from foreign country out - in)
Where do short run Phillips curve and long run Phillips curve intersect
where Actual Inflation = Expected Inflation
Working age population
working age pop = labor force + not in labor force
The nominal interest rate is the a. interest rate corrected for inflation. b. interest rate as usually reported by banks. c. real rate of return to the lender. d. real cost of borrowing to the borrower.
B
Labor force
Labor force = employed + unemployed
Labor Force participation rate
Labor force participation rate = labor force/working age population
What is MPC
MPC = change in consumption/ (change in (Y-T) + TR) aka = change in consumption/ change in Y^D Disposable income = Y^D = total taxes + Total Returns
Current Account
Negative of (-) financial account
NAIRU
Non accelerating Inflation Rate of Unemployment - unemployment rate at which the inflation rate has no tendency to increase or decrease
Nominal GDP
P1Q1 + P2Q2 ... PnQn
Real GDP
P1bQ1 + P2bQ2 ... PnbQn
frictional unemployment
People in between jobs
Structural unemployment
People's skills are out of date/ they need to be retrained
Convergence
Poor countries catch up to rich countries
Philips curve
Shows tradeoff btw unemployment and inflation - offers policy members a menu of choices because it affects AD - Vertical in long run - slopes downward in short run
Marginal Propensity to Consume (MPC)
The slope of the consumption function: The amount by which consumption spending changes when disposable income changes
Unemployment Rate
Unemployment Rate = number unemployed/ Number in labor force
Calculating Current Price of a Past Price
Value in time (t) + n dollars = value of time (t) dollars SO (Pt + N) / Pt --> later yr/ earlier year
Levels form of Velocity
Velocity = Nominal GDP/ Money Supply OR (P x Y)/ M --> MV = PY
Balanced Trade
When exports = imports
Government spending (G) increases --> AD???
Increases or shifts RIGHT
Interest Rate (r) decreases--> Consumption (C) increases--> Investment (I) increases--> Net Exports (NX) increases --> AD ???
Increases or shifts RIGHT
Taxes (T) decrease --> AD ???
Increases or shifts RIGHT
Inflation
Inflation: Economy's overall price level rising Inflation = (P in later year - P in earlier year/ P in earlier year) x 100
Investment
Investment = change in K
Change in money supply
Change in money supply = change in total deposits + Change in cash held by public
Change in total deposits
Change in total deposits = 1/ (R + E) x Initial change in Reserves
Household wealth
Household wealth = household assets - household liabilities
Y dom (Domestic GDP) DECREASES
Imports (IM) decreases, (X-IM) increases, NX increases
Y dom (Domestic GDP) INCREASES
Imports (IM) increases, (X-IM) decreases, NX decrease
In the short run, open-market purchases by the Fed a. increase the price level and real GDP. b. decrease the price level and real GDP. c. increase the price level and decrease real GDP. d. decrease the price level and increase real GDP.
A
Growth Rate of Population
% Change in GDP - % Change in population
Growth rate of per capita GDP
% change in GDP/ population
Growth Rates form of velocity
% change in M + % change in V = % change in P + % Change in Y ****** In the long run % change in V = 0 AND * change in M does NOT affect % change in Y
Long run growth rates form of velocity
% change in M = % change in P + % Change in Y OR % change in P = % change in M - % Change in Y AKA Inflation = % change in M - % Change in Y
GDP Deflator
(Nominal GDP/ Real GDP) x 100
Wage increase (buying power in new year compared to old)
(old wage x new CPI) / Old CPI
Real percentage increase
(old wage x new CPI) / Old CPI = x Use answer from above equation, subtract is from NEW wage, divide by old wage, then x100 [(New wage -x)/ old wage] x100
What determines productivity
- Capital - human capital ( knowledge and skills acquired through education and training) - Technological change - increases the quantity of outputs firms can produce with given inputs
Short run Phillips curve
- Downward sloping cause everywhere on the curve, expected inflation is the same *** BUT ppl's expectations can be wrong - Monetary policy can reduce unemployment rate below natural rate by making inflation greater than expected
Environmental approach to development
- Geography - Disease - Climate - Inaccessibility of trade routes (aka landlocked) - Lack of natural resources - Policy implications (foreign aid)
Influences of natural rate of unemployment
- Gov policies (training programs, Unemployment compensation, labor marker policies, minimum wage laws) - labor unions (keep wages above equilibrium) - Efficiency wages (wages set by employer above equilibrium to make workers more efficient)
Expansionary Fiscal Policy
- Gov spending (G) increases - Taxes decrease - And/ or Transfer Payments (unemployment compensation, social security, etc) increase G increases, TR increases, Taxes decrease, disposable income increases, Consumption spending increases, AD increases
Tax multiplier
- MPC/ 1 -MPC
For movement up and down curve:
- Price level (P) increases --> GDP (Y) decreases - Price level (P) decreases --> GDP (Y) increases
Wealth Effect
- Price level (P) increases --> purchasing power of household wealth decreases --> Consumption (C) decreases--> Aggregate expenditure (AE) decreases - and vice versa
Interest Rate Effect
- Price level (P) increases--> Interest Rate (r) increases--> Consumption (C) decreases, Investment (I) decreases, Net Exports (NX) decreases--> AE decreases - and vice versa
International Trade Effect
- Price level (P) increases--> real exchange rate (e) increases--> Net Exports (NX) decreases--> AE decreases - and vice versa
Institutional Approach to development
- sounds legal system - stable political system - monetary stability - reduced corruption
3 approached of development
1) Environmental Approach 2) International trade approach 3) Institutional approach
Why do we expect convergence
1) Technological transfer 2) Poor counties attract more capital
MPS (marginal propensity to save)
1- MPC
3 sources of technological change
1. better machinery - computers software, machine tools 2. Increase in human capital - Education, training experience 3. Better organization and management of production
Government Spending multiplier
1/ (1-MPC)
Money multiplier
1/ (R + E) * R = reserve requirement *E = Excess Reserves
International Trade approach to development
2 dimensions of integration - capital flows --> financial capitals, FDI - Trade in goods and services --> import substituting industrialization *** this approach is in favor of globalization

A is this cause our investment in them is doing well and their investment is us is doing badly?
Global funds market
A global fund is a fund that invests in companies located anywhere in the world including the investor's own country. A global fund often seeks to identify the best investments from a global universe of securities. Global funds may also be passively managed. A global fund can be focused on a single asset class or allocated to multiple asset classes.

Foreign Portfolio Investment
Capital Investment financed with foreign money but operated by domestic residents Ex: investing in a foreign company
Foreign Direct Investment
Capital Investment owned and operated by a foreign entity ex: a factory or office building for a company operated in another place

Per worker production function
Diminishing marginal returns to capital - if worker has little K, giving them more increases their productivity - If workers already have a lot of K, giving them more increases production fairly littler
Net Foreign Investments (NFI)
Domestic residents' purchases of foreign assets minus foreigners' purchase of domestic assets
Monetary Policy
Done ONLY by the Fed
Fiscal Policy
Done by the Treasury Dept, at the direction of the legislative or executive branch
Long Run Phillips curve
Expectations CATCH UP to reality, the unemployment rate goes back to natural rate WHETHER inflation is low or high
Natural rate of unemployment
Frictional + Structural

d
r us (US interest rate) INCREASES [relative to rest of world]
demand for $ increases, Nominal interest rate (E) increases, Real interest rate (e) increases, Exports (X) decreases, Imports (IM) increases, NX decreases
Real Exchange Rate (e)
e = (P dom x E)/ P for
IF Purchasing Power Parity holds
e = 1 --> E = P foreign - P domestic if e>1, then E is TOO HIGH
Y for (Foreign GDP) DECREASES
exports (X) decreases, (X-IM) decreases, NX decreases
Real interest rate (e) INCREASES
exports (X) decreases, Imports (IM) increases, Net Exports (NX or X - IM) decreases
Y for (Foreign GDP) INCREASES
exports (X) increases, (X- IM) increases, NX increases
Real interest rate (e) DECREASES
