ECON 2133 – Class Outline 1

Introduction

ECONOMICS: The study of how people allocate theirlimited resources to try to satisfy their unlimited wants.

Limited resources

versus unlimited wants

implies (economic) scarcity

And scarcity implies that we must make choices

So, Economics is the study of how people make choicesin the context of economic scarcity.

MICROECONOMICS: The study of how households and firmsmake decisions and interact in markets.

MACROECONOMICS: The study of the economy at the aggregate level (i.e., as a whole) including

 Total output of the economy (GDP)

 Employment / unemployment

 Changes in overall price levels (inflation)

 Economic growth, productivity, and living standards

 How govt. actions affect the economy (monetary and fiscal policy)

Chap. 4: Macroeconomic Issues

Econ. Growth: Increasing ______of goods and services by an economy over ______

(i.e., incr. real GDP)

See pgs. 90 – 92 & Fig. 1, p. 91

Living Standards: ______per ______(GDP / population)

Productivity: ______per ______(GDP / # of workers)

Rf. Chap. 8

Employment / Unemployment

Unemployment rate: the ______of the ______not working.

See pgs. 92 – 94 & Fig. 2, p. 93

Short run s in the U rate are largely explained by ______

See pgs. 93 – 94 & Fig. 3, p. 94

Price levels and inflation

Price level (or index): A number that indicates the ______level of prices at a given time, relative to the level at a “______” time

E.g.PLt = 1.2

PLb = 1.0

implies that prices at time t are _____% higher than at time b

Inflation: ______price levels over time

See pgs. 95 – 96 & Fig. 4, p. 95

The study of macroeconomics involves ______

See pgs. 96 - 97

E.g. Y = C + I + G + NX

Marcoeconomic policy: ______actions that affect the economy’s performance over time

Monetary policy influences the economy’s ______

 Fiscal policy - govt. ______and ______decisions that affect the economy

Structural policy affects the basic way in which the economy works

Positive analysis studies “what is” and predicts “what will be” under given economic conditions (measurement; scientific analysis)

Normative analysis: “what ought to be”

goes beyond positive anal. to express one’s value judgments

See p. 5 - 6, 98 - 99

Chap. 5 – Basic Macroeconomic Measures

Symbology

___total output of products by an econ. (i.e., gross domestic product - acronym GDP)

___“nominal” GDP

___“real” GDP

___disposable (personal) income

___personal consumption expenditures

___personal saving

___ (or Tx)tax payments or receipts

___capital investment spending

___govt. purchases of goods and services (govt. spending)

___consumer price index

___GDP deflator (a price index)

___annual inflation rate (%)

___unemployment rate (%)

The “Big Three” - Yr, U, 

GDP: the total market value of all final goods and services produced within a nation annually.

 ______products only

 Only ______products

 No purely ______transactions or ______transfers

Study pg. 104 - 107

Three ways to measure GDP:

Expenditures approach

Y = C + I + G + NX

C =

I =

G =

NX =

(NX = Ex - Im)

Ex = exports

Im = imports

See pg. 107 - 113

Practice: Do Pb. 1 (pg. 47 - 48, study. guide)

Factor payments approach

Y = w + i + r + pr + (tx (bus) + kd)

Ynd(net domestic product)

Ynat(national income)

Ypers(personal income)

Disposable (personal) income

Yd = Ypers - Tx

Yd = C + S(“allocations equation”)

See pg. 114 - 116

Value added approach

Y =  value added for all final products (in all stages of their production)

Value added = ______value of a product minus cost of ______inputs (from earlier stages of production) See pg. 114

Real vs. Nominal GDP

Nominal GDP (Yn): the production of products valued at ______prices

Real GDP (Yr): the production of products valued at ______(base year) prices

GDP deflator (Dy): a ______price index that measures changes in ______- ______price levels

See pg. 116 - 117

For any year x

Yr(x) = Yn(x) / [Dy(x) / 100]

E.g.Yn(x) = $8760 bil.

Dy(x) = 102.8

Yr(x) = ______/ [______/ ____ ] = $______bil.

More on PIs in Chap. 6

Uses of & problems with GDP measurements -- pgs. 117 - 120

Labor-related measures - Definitions

 Employed

 Unemployed

 Not in labor force

Labor force = employed + ______

Unemployment rate

U(%) = (Unemployed / ______) * 100

See Fig. 3, p. 124

Labor force participation rate

LFPR(%) = (Labor force / ______) * 100

See pgs. 126 – 129 & Fig. 5 (p. 127), Fig. 6 (p. 128

Types of unemployment

Frictional

Seasonal

Structural

Cyclical

See pgs. 120 - 123

“Full employment” is when ______unemployment = ___

See pg. 123

“Costs” of U - pgs. 123 - 126

Chap. 6 - Price levels and inflation

Study concepts of

Price level(base = _____)

Price index(base = ______)(pg. 140)

PI(t) = Cost of “mkt. basket” in year t

------x 100

Cost of “mkt. basket” in base yr.

E.g. CPI2004 = 2004 cost of mkt. basket

------x 100

1983 cost of mkt. basket(pg. 141)

To calculate an annual ∏ (inflation) rate from a PI:

∏(t) = PI(t) – PI(t-1)

------x 100

PI(t-1)(pg. 142)

Note that ∏(t) will be a percentage number

E.g.PI(t) = 130PI(t-1) = 120

∏(t) = [(_____ – _____ / _____] x 100 = ______%See Fig. 1, p. 143

How the CPI and Dy differ

CPI mkt. basket is products typically bought by U.S.

______-- C and Im

DY mkt. basket is products ______in the U.S. economy

C, I, G, and Ex

Using a PI to calc. “real” values from “nominal” values

Yn(b) = $5000 bil.Yn(t) = $6600 bil.

Dy(b) = 100Dy(t) = 125

Yr(t) = Yn(t) / (Dy(t) / 100)

Yr(t) = $______bil. / (_____ / _____) = $______bil.

vs.

Yr(b) = $5000 bil.Why?

Any PI series will have a base year.

For the base year, the PI = 100.0 - both by calculation and definition.

If a price level (PL) series, the base year value = 1.0

See pg. 145

The current CPI base is 1982 - 1984 avg. prices, with a 2002 mkt. basket.

Application: See Table 2, p. 145

CPI is not a perfect measure of price changes - it likely overstates the  rate by 1 - 2 %

Why?

______in product quality

_____ products (not in “mkt. basket”)

______when relative prices of products change

See pg. 151 - 152

The “costs” of 

______purchasing power of money

Decreases ______

Redistributes ______

Causes ______of resources

See pg. 145 - 151

Nominal and Real Interest Rates

r = i - r is real interest rate

i is nominal interest rate

E.g.i = 10% = 4%

So that r = ___%(pg. 148)
