Economic Norms


An overview of what the percentages of GDP, unemployment, and inflation rates indicate about the economy.

Types of Unemployment

Unemployment→failure to use available resources (labor)
Employed→includes those that are self-employed

Unemployed:
  1. new entrants
  2. reentrants
  3. laid off
  4. lost last job (fired)
  5. quit last job
NOT in labor force:
  • military (armed services)
  • homemakers
  • students
  • retirees
  • disabled people
  • those in mental institutions
  • prisoners
Frictional
·         temporary, transitional, short-term (searching for job, in between jobs)
·         signals new jobs are available and reflects freedom of choice
·         people quit/got fired, or looking for a better job
·         graduates from college
Cyclical
·         economic downturn in business cycle (4)
·         deficient demand for goods and services (caused by recession)
·         jobs do come back (same one or another in field)
Structural
·         Deals w/ tech. 1) automation→job may become obsolete due to change in consumer tastes 2) creative destruction; as jobs are created, others are lost 3) change in skills (ex. NASA→cut program)
Seasonal
·         Jobs dependent on seasons/weather (ex. Lifeguard, Santa Claus, Easter Bunny, construction workers)


Unemployment rate formula→
(# of unemployed/total labor force-# of unemployed+# of employed-)x100
**standard unemployed rate>4-6%

Full employment (FE)→natural rate of unemployment (NRU)
  • equal to structural and frictional unemployment
  • FE does NOT mean 0 unemployment
Okun's Law:
  • describes how unemployment relates to a nation's GDP
  • states that for every 1% unemployment above the NRU, a (-) GDP gap of 2% will occur
Unequal burdens of unemployment:
  1. rates are lower for white-collar workers
  2. teens have highest rates
  3. blacks have higher rates than whites
  4. rates for males and females are comparable

Types of Inflation

Inflation→rise in general level of pricing; 2-3% inflation rate is wonderful ($ today can buy less than it did yesterday)
Deflation→decline in general price level (many industrious nations)
Disinflation→occurs when inflation rate itself declines

Solving inflation problems:
  • Rule of 70→# of years it takes to double inflation (70/annual inflation rate)
  • inflation rate→(current year price index-prior year price index)/prior year price index
Finding real interest rates: (real interest rate=nominal interest rate-inflation)→single digit #s
  • Real interest rate→cost of borrowing/lending $ that's adjusted for expected inflation (always expressed as a %)
  • Nominal interest rate→unadjusted cost of borrowing/lending $ (expressed as %)
Causes of Inflation:
  • Demand-pull→caused by an excess of demand over output that pulls prices ↑; output and emplyment rise while price level is also rising; spending increases faster than production 1) ↑ in govt purchases 2) excessive increases in $ supply (create condition called "hyperinflation"→rapid rise in inflation rate 3) rising incomes as economy approaches full employment output
  • Cost-push (supply side economics)→caused by rise in per unit production soct due to increasing resource costs; 2 sources 1) supply shocks→dramatic rise in energy or raw material prices due to input shortages or a growing demand for inputs 2) price wage spiral→where workers seek higher wages to offset higher consumer prices
Effects of Inflation:

-Anticipated~
-Unanticipated: has stronger effects because those expecting inflation may be able to adjust their work/spending habits to avoid/lessen effects
-Both: wages/pensions may have "cost of living adjustments" (COLAs) built in to offset anticipated inflation
  1. fixed income groups (ex. grandparents) will be hurt→real income suffers (nominal income does not rise w/ prices)
  2. savers will be hurt i.e. inflation takes away from interest earned on account (interest doesn't rise w/ prices)
  3. borrowers can be helped by unanticipated inflation while lenders are hurt (debts will be repaid w/ cheaper $ than ones loaned out)

GDP

Gross Domestic Product (GDP):
  • total value of all final goods and services produced in U.S. in a given (one) year
  • includes all production and income earned w/in U.S. by U.S. and foreign producers
  • does NOT include production outside U.S., even by Americans
Gross National Product (GNP):
  • total value of all final goods and services produced by Americans in a year
  • includes production or income by Americans anywhere in the world
  • excludes production by non-Americans, even in the U.S.
Formula for GDP→C+Ig+G+Xn
  • C=personal consumption (67%); purchases of finished goods and services
  • Ig=Gross Private Domestic Investment; new factory equipment; construction of housing; factory equipment maintenance; unsold inventory built in a year
  • G=Govt spending (ex. buy airplanes, buses)
  • Xn=net exports (exports-imports)
Items NOT Counted in GDP:
  • used/second-hand goods
  • gifts (scholarships)
  • stocks and bonds (recycling $)
  • unreported business activities (cash tips)
  • illegal activities (selling drugs, mafia)
  • financial transactions between banks (switching $) and businesses
  • intermediate goods→used to finish product
  • non-market activities (babysitting, volunteering)
Expenditure Approach→C+Ig+G+Xn=GDP
  • income generated from production of goods and services
Income Approach→W+R+I+P (wages+rents+interest+profits+statistical adjustments)→make balanced
  • add all income generated from production of final output
**expenditure and income approach MUST be equal

Net Domestic Product (NDP)→GDP adjusted for depreciation (consumption of fixed capital)

National Income (NI)→income earned by American-owned resources, whether it is here/abroad
  1. Net National Product (NNP)-Indirect Business Taxes (IBT)
  2. CE+RI+II+CP+PI (compensation employee+rental income+interest income+corporate profits+proprietor’s income)
  3. GDP-IBT-Depreciation-Net Foreign Factor Payment
Personal Income (PI)→income received by households regardless of source

Disposable Personal Income (DPI)→after tax income, available for household consumption
  • NI-Household Taxes (HT)+Govt Transfer Payments (GTP)
Nominal GDP (NGDP)→measures GDP in current dollars, no matter what output is (PxQ)

  Real GDP (RGDP)→measures GDP in constant dollars, adjusted for inflation

GDP Deflator→measure of level of prices of all new domestically produced final goods and services in economy
  • (NGDP/RGDP)x100
Inflation rate→a rise in the general level of prices
  • (price index in year 2 (current year)-price index in year 1 (previous year))/price index in year 1 (previous year)
Consumer Price Index (CPI)→most widely used measure of overall price level in U.S.
  • (price of market basket in particular year/price of same market basket in previous year)x100
GNP=GDP+Net Foreign Factor Payment
Net Private Domestic Investment+Depreciation=Gross Private Domestic Investment

*Net Domestic Product=GDP-Depreciation

*Budget=Govt Purchases of G&S and Govt Transfer Payments-Govt Tax & Fee Collections

*Trade=Exports-Imports

    Circular Flow Model


    Learn the Circular Flow Model from this amazing guy.

    Unit 2: Types of Economies

    Types of Eco. Systems:
    1. Command (aka "centrally planned")-govt owns capital and land; controls labor (ex. Cuba)
    2. Traditional-based on habits, rituals, and customs; decisions made by elders; discourages new ideas and technology (ex. tribes)
    3. Mixed-businesses regulated by govt to protect public's interest (ex. U.S., Canada, Mexico)
    4. Free Market-people and firms act in own best interest; buyers and sellers exchange goods and services (ex. Hong Kong-only true free market)
    Three Eco. Questions:
    1. What goods and services should be produced?
    2. How should these goods and services be produced?
    3. Who will consume these goods and services?
    Market→an institution that allows buyers and sellers to trade
    Households→a person or group of people that share an income
    Firms→organization that produces goods and services for sell

    Product Market
    Factor Market (aka “Resource Market”)
    ·         Buyer usually consumer
    ·         Seller is a firm
    ·         Factors of production (4-land, labor, capital, entrepreneurship)
    ·         Buyer usually firm
    ·         Seller is factor owner
