- 5. GDP – The Measure of National Output Gross Domestic Product Market value of all final goods and services produced within a country during a given time period Market value – price x quantity produced Final goods – any new good that is ready for use by a consumer GDP excludes intermediate goods (one’s that are used to make others) GDP excludes secondhand sales (sale of used goods) Produced within a country – foreign owned firms that produce within the borders COUNT towards GDP Given time period – look at quarterly GDP & yearly Most important is the growth rate of GDP Issues with GDP – leaves out unpaid household & volunteer work, ignores informal/underground economy, says nothing about income distribution, doesn’t show what was exactly produced
- 7. Significance of GDP Analysis We have seen low GDP growth recently…it means we haven’t quite recovered yet!

- 14. Inflation Rate Definition: the percentage increase in the average price level of goods & services from one month/year to the next Consumer Price Index (CPI) price index for the “market basket” of consumer goods & services Called the “cost-of-living” index Primary measure of inflation in the U.S. Market basket based on thousands of surveys of households about spending habits and then BLS tracks price changes of these items each month

- 30. Phases of the Business Cycle Phase: Expansion- period of increasing real GDP (we’re producing more!) Recovery– period when the economy begins to produce more again Phase: Contraction- period of decline in real GDP (we’re producing less!) Recession– when real GDP declines for two consecutive quarters or six months Depression– prolonged economic downturn characterized by extreme conditions – plummeting GDP, extremely high unemployment, bank/business failures, etc.
- 31. Phases of the Business Cycle Phase: Peak – point where real GDP stops going up Phase: Trough– point where real GDP stops going down

- Each quarter, the Bureau of Economic Analysis (BEA), an agency of the U.S. Department of Commerce, releases an estimate of the level and growth of U.S. gross domestic product (GDP), the output of goods and services produced by labor and property located in the United States.What Does / Does Not Count Towards GDP: 2) Includes those goods produced in the USA, even if the company is owned by foreign firms or U.S. owned companies elsewhere do not countJapanese cars made in Ohio count 3) Intermediate Products aren’t countedProducts used in making other products (like new tires on a car) but replacement tires do count (flour, sugar, salt bought as end product counts but not what goes in bakery items) 4) Excludes Secondhand Sales- Sale of used goods (does not accumulate new wealth)5) Informal economy –operates without gov’t regulation - babysitters, drug dealers, mowing lawns etc. 6) unpaid work – volunteer firefighter & stay at home parents provides value but no $ is exchanged so can’t count in GDPOther GDP limitations 1. Reporting delays - too much info to report on present 2. tells nothing about the composition of output (up usually is good but what if it is creating nerve gas instead of public works, down usually bad but could be new drug that saves on medical costs 3. or the impact of production on quality of life. 4. Excludes non-market transactions - mowing lawn or housekeepingGDP is still the best measure of overall economic health because it only measures production within a nation’s borders! = want more production
- "U.S. Economy Grows at a 5.9% Rate"The Bureau of Economic Analysis' announcement about real GDP growth in late 2009 seemed like very good news. The U.S. economy grew at an annualized rate of 5.9 percent from October through December. Given the real GDP declines of much of the previous two years, was this evidence that the recession is over? Using GDP as an indicator that some people feel identifies a recession, maybe it is over. Then again, the National Bureau of Economic Research uses much more than simple GDP growth to identify the beginning and end of a recession.
- Switched from GNP to GDP in 1991= GDP + all payments that Americans receive from outside the United States minus all payments made to foreign-owned resources inside the United States.Personal Income (PI) is the total amount of income received by individuals before taxes.Disposable Personal Income (DI) is PI less taxes (personal income taxes).What’s the difference between GDP & GNP? Not equal (GDP is measure of all final goods & services produced in U.S. no matter who & GNP is all goods & services produced by U.S. citizens no matter where they are from
- CPI -This is one way the government measures inflation. It is termed as the “market basket of consumer good and services.” or-changes in the average prices of this basket changes overall cost of living – COL index-surveys thousands of households about their spending habits to create market basket then visits 25,000 retail stores to get price changes The BLS measurement of the CPI-U includes all urban consumers, representing about 87 percent of the total U.S. population. "It is based on the expenditures of almost all residents of urban or metropolitan areas, including professionals, the self-employed, the poor, the unemployed, and retired people, as well as urban wage earners and clerical workers. Not included in the CPI are the spending patterns of people living in rural non-metropolitan areas, farm families, people in the Armed Forces, and those in institutions, such as prisons and mental hospitals." With a few exceptions, these price indexes are seasonally adjusted. According to the BLS, "many economic series, including the CPI, are adjusted to remove the effect of seasonal influences-those which occur at the same time and in about the same magnitude every year. Among these influences are price movements resulting from changing weather conditions, production cycles, changeovers of models, and holidays."Calculating the CPI-U"The CPIs are based on prices of food, clothing, shelter, and fuels, transportation fares, charges for doctors' and dentists' services, drugs, and other goods and services that people buy for day-to-day living. Prices are collected each month in 87 urban areas across the country from about 4,000 housing units and approximately 25,000 retail establishments-department stores, supermarkets, hospitals, filling stations, and other types of stores and service establishments. All taxes directly associated with the purchase and use of items are included in the index.""Prices of fuels and a few other items are obtained every month in all 87 locations. Prices of most other commodities and services are collected every month in the three largest geographic areas and every other month in other reas. Prices of most goods and services are obtained by personal visits or telephone calls of the Bureau's trained representatives.""In calculating the index, price changes for the various items in each location are averaged together with weights, which represent their importance in the spending of the appropriate population group. Local data are then combined to obtain a U.S. city average."
- Price level – magnitude of prices at one point in time (used in comparison over time)The inflation rate is determined by comparing the price level at the beginning and end of a period.Deflation can occur when there is a decrease in the general price level.Types describing severity of inflation –Creeping inflation is inflation in a range of 1 to 3 percent annually.Galloping inflation is when inflation can go as high as 100 to 300 percent annually.Inflation of more than 500 percent a year is known as hyperinflation. (record 828 octillion worth of one prewar pengo)We can also end up with situations where the general price of goods falls throughout the marketThis results in deflationCalculated the same way as inflation, BUT results in a negative number
- Demand-Pull : consumers/business converge to buy up goods & services so merchants have to raise prices (lose customers though)Cost-Push : example – union wins large wage contract = increased cost of producing goods & then pass price to customers = rise in pricesWage-Price Spiral : higher prices = people ask for higher wages creates spiral, if workers get higher wages then merchants increase pricesExcessive monetary growth – any extra money given & then spent will cause demand-pull
- The dollar buys less – today our dollar buys 5 cents worth of goods & services bought in 1900 (prices rise & purchasing power decreases)Spending habits changeDisrupts economy – interest rates increase too so less spending on housing & durable goods (businesses stop expanding & cut back inventories/production)Speculation increasesRisky spending – people who usually invest in safe options now buy condos, diamonds, works of art or things that increase in price (don’t invest in normal things) people don’t want savings to go worthless so SPEND now to take advantage of lower pricesLenders are hurt; negative effect on economy loans made earlier are repaid with inflated dollars (ones with less purchasing power) – loan of $100 to buy 200 loaves of bread but once inflation sets in price doubles to $1 a loaf = only 100 loaves for lender
- Each month, the Bureau of Labor Statistics (BLS) releases data from the monthly "Household Survey" conducted by the Bureau of the Census, providing a comprehensive body of information on the employment and unemployment experience of the U.S. population, classified by age, sex, race, and a variety of other characteristics.The BLS also conducts the Current Employment Statistics (CES) program, surveying about 150,000 businesses and government agencies, representing approximately 390,000 individual work sites, in order to provide detailed industry data on employment, hours, and earnings of workers on nonfarm payrolls.The BLS compiles information from these sources and announces the monthly "Employment Situation," reporting the current U.S. employment and unemployment data estimates. The monthly announcement reports employment data from the previous full month.Education matters. Those with less education tend to be unemployed at higher rates. The group with the lowest identified unemployment rate in March was people with a Bachelors Degree or higher, at 4.9 percent. Those without a high school diploma had an unemployment rate almost 3 times higher, at 14.5 percent. Figure 2: U.S. Unemployment Rates, March 2010U.S. Unemployment Rate by Demographic Group Civilian Non-institutionalized Population 9.7% Men (20 years and over) 10.0% Women (20 years and over) 8.0% Teenagers 26.1% Whites 8.8% Black/African Americans 16.5% Hispanics/Latino Ethnicity 12.6% Asians 7.5% U.S. Unemployment Rates by Educational Attainment All adults, 25 years and over 8.3% Less than HS Diploma 14.5% HS Graduates, no college 10.8% Some College, Associate Degree 8.2% Bachelors Degree and Higher 4.9% Additional Unemployment Data “The number of long-term unemployed (those jobless for 27 weeks and over) increased by 414,000 over the month to 6.5 million. In March, 44.1 percent of unemployed persons were jobless for 27 weeks or more.” As the recession continues, larger numbers are unemployed for a longer time. Those analysts concerned that this will be a “jobless recovery” believe that many of the long-term unemployed will not find jobs in their old industries, as investments in technology replace employees. “The civilian labor force participation rate (64.9 percent) and the employment-population ratio (58.6 percent) continued to edge up in March.” “The number of persons workingpart time for economic reasons (sometimes referred to as involuntary part-time workers) increased to 9.1 million in March. These individuals were working part time because their hours had been cut back or because they were unable to find a full-time job.” “About 2.3 million persons were marginally attached to the labor force in March, compared with 2.1 million a year earlier. (The data are not seasonally adjusted.) These individuals were not in the labor force, wanted and were available for work, and had looked for a job sometime in the prior 12 months. They were not counted as unemployed because they had not searched for work in the 4 weeks preceding the survey.” “Among the marginally attached, there were 1.0 million discouraged workers in March, up by 309,000 from a year earlier. (The data are not seasonally adjusted.) Discouraged workers are persons not currently looking for work because they believe no jobs are available for them. The remaining 1.3 million persons marginally attached to the labor force had not searched for work in the 4 weeks preceding the survey for reasons such as school attendance or family responsibilities.” Many have simply given-up looking for work. Others are working only part-time, not by choice.
- Frictional – between jobs for one reason or another such as looking for a better job or a first time workerStructural – consumer tastes make some goods & services not in demand (horses, whips, saddles to U.S. automobiles & then to foreign made automobiles) gov’t closes military bases, occurs with fundamental change in operations of the economy Cyclical – people are laid off during recession (cut back production), = people stop buying cars, fridges, washers, dryersSeasonal – resulting in changes of weather or demand for certain produts – carpenters work less in winter (seasonal takes place every year but cyclical may last 3-5 years)Technological – workers with less skills, talent, education are replaced by machinesDIFFERENCE BETWEEN STRUCTURAL & TECHNOLOGICAL - factors unrelated to efficient means of production can cause structural unemploy. But in your laboring days, you'll want to make sure not to choose a job that is going to be made obsolete by technology. There's not much need anymore for telegraph operators or horse-and-buggy drivers; the telephone and automobile did those jobs in.A few jobs that are likely to go down as the horse-and-buggy drivers of the 21st century, probably sooner than later:Bank teller, Telephone operator, Photo processor, Video store clerk, Newspaper classifieds salesperson
- Incomes in manufacturing had dropped by 70 percent, and incomes in construction had dropped by more than 80 percent. Government was the only industry that had grown over the period.
