Chapter 9: Production and Productivity

1. Chapter 9:Production and Productivity

2. GDP: Gross Domestic Product • Economists monitor the macroeconomy using national income accounting, a system that collects statistics on production, income, investment, and savings. • Gross domestic product (GDP) is the dollar value of all final goods and services produced within a country’s borders in a given year. • GDP does not include the value of intermediate goods. • Intermediate goods are goods used in the production of final goods and services.

3. Calculating GDP The Expenditure Approach • The expenditure approach totals annual expenditures on four categories of final goods or services. 1. Consumer goods and services 2. Business goods and services 3. Government goods and services 4. Net exports or imports of goods or services. The Income Approach • The income approach calculates GDP by adding up all the incomes in the economy. • Consumer goods include durable goods, goods that last for a relatively long time like refrigerators, and nondurable goods, or goods that last a short period of time, like food and light bulbs.

4. Nominal GDP is GDP measured in current prices. It does not account for price level increases from year to year. Real GDP is GDP expressed in constant, or unchanging, dollars. GDP Deflator is a price index that reduces prices into a base year. Nominal and Real GDP Year 1 Nominal GDP Year 2 Nominal GDP Year 3 Real GDP Suppose an economy‘s entire output is cars and trucks. In the second year, the economy’s output does not increase, but the prices of the cars and trucks do: To correct for an increase in prices, economists establish a set of constant prices by choosing one year as a base year. When they calculate real GDP for other years, they use the prices from the base year. So we calculate the real GDP for Year 2 using the prices from Year 1: This year the economy produces: 10 cars at $16,000 each = $160,000 + 10 trucks at $21,000 each = $210,000 Total = $370,000 10 cars at $15,000 each = $150,000 + 10 trucks at $20,000 each = $200,000 Total = $350,000 This new GDP figure of $370,000 is misleading. GDP rises because of an increase in prices. Economists prefer to have a measure of GDP that is not affected by changes in prices. So they calculate real GDP. Since we have used the current year’s prices to express the current year’s output, the result is a nominal GDP of $350,000. 10 cars at $15,000 each = $150,000 + 10 trucks at $20,000 each = $200,000 Total = $350,000 Real GDP for Year 2, therefore, is $350,000 Real and Nominal GDP Chart taken from: Prentice Hall

5. Limitations of GDP • GDP does not take into account certain economic activities: • Nonmarket Activities GDP does not measure goods and services that people make or do themselves, such as caring for children, mowing lawns, or cooking dinner. • Negative Externalities Unintended economic side effects, such as pollution, have a monetary value that is often not reflected in GDP. • The Underground Economy There is much economic activity which, although income is generated, never reported to the government. Examples include black market transactions and "under the table" wages. • Quality of Life Although GDP is often used as a quality of life measurement, there are factors not covered by it. These include leisure time, pleasant surroundings, and personal safety.

6. Other input and Output Measures Gross National Product (GNP) • GNP is a measure of the market value of all goods and services produced by Americans in one year. Net National Product (NNP) • NNP is a measure of the output made by Americans in one year minus adjustments for depreciation. Depreciation is the loss of value of capital equipment that results from normal wear and tear. National Income (NI) • NI is equal to NNP minus sales and excise taxes. Personal Income (PI) • PI is the total pre-tax income paid to U.S. households. Disposable Personal Income (DPI) • DPI is equal to personal income minus individual income taxes.

7. Measurements of the Macroeconomy – income earned outside U.S. by U.S. firms and citizens income earned by foreign firms and foreign citizens located in the U.S. + = Gross Domestic Product Gross National Product – Gross National Product Net National Product depreciation of capital equipment = – Net National Product = National Income sales and excise taxes • firms‘ reinvested profits • firms‘ income taxes • social security – + = National Income Personal Income other household income – = Disposable Personal Income Personal Income individual income taxes Key Macroeconomic Measurements Prentice Hall

8. Factors Influencing GDP Aggregate Supply • Aggregate supply is the total amount of goods and services in the economy available at all possible price levels. • As price levels rise, aggregate supply rises and real GDP increases. Aggregate Demand • Aggregate demand is the amount of goods and services that will be purchased at all possible price levels. • Lower price levels will increase aggregate demand as consumers’ purchasing power increases. Aggregate Supply/Aggregate Demand Equilibrium By combining aggregate supply curves and aggregate demand curves, equilibrium for the macroeconomy can be determined.

9. How do Economists Measure Economic Growth How do economists measure economic growth? What is capital deepening? How are saving and investing related to economic growth? How does technological progress affect economic growth? What other factors can affect economic growth?

10. Measuring Economic Growth GDP and Population Growth • In order to account for population increases in an economy, economists use a measurement of real GDP per capita. It is a measure of real GDP divided by the total population. • Real GDP per capita is considered the best measure of a nation’s standard of living. GDP and Quality of Life • Like measurements of GDP itself, the measurement of real GDP per capita excludes many factors that affect the quality of life. • The basic measure of a nation’s economic growth rate is the percentage change of real GDP over a given period of time.

11. Capital Deepening The process of increasing the amount of capital per worker is called capital deepening. Capital deepening is one of the most important sources of growth in modern economies. Firms increase physical capital by purchasing more equipment. Firms and employees increase human capital through additional training and education.

12. How Saving Leads to Capital Deepening Shawna’s income: $30,000 $25,000 spent $5,000 saved $3,000 in a mutual fund (stocks and corporate bonds) $2,000 in “rainy day” bank account Bank lends Shawna’s money to firms in forms such as loans and mortgages Mutual-fund firm makes Shawna’s $3,000 available to firms Firms spend money on business capital investment The Effects of Savings and Investing • The proportion of disposable income spent to income saved is called the savings rate. • When consumers save or invest, money in banks, their money becomes available for firms to borrow or use. This allows firms to deepen capital. • In the long run, more savings will lead to higher output and income for the population, raising GDP and living standards. Prentice Hall

13. Technological Process • Besides capital deepening, the other key source of economic growth is technological progress. • Technological progress is an increase in efficiency gained by producing more output without using more inputs. • A variety of factors contribute to technological progress: • Innovation When new products and ideas are successfully brought to market, output goes up, boosting GDP and business profits. • Scale of the Market Larger markets provide more incentives for innovation since the potential profits are greater. • Education and Experience Increased human capital makes workers more productive. Educated workers may also have the necessary skills needed to use new technology. • New products • New method of production • New ways of organizing production of marketing products • New methods of communication can each demonstrate how productivity increases

14. Other factors affecting growth: Population Growth • If population grows while the supply of capital remains constant, the amount of capital per worker will actually shrink. Government • Government can affect the process of economic growth by raising or lowering taxes. Government use of tax revenues also affects growth: funds spent on public goods increase investment, while funds spent on consumption decrease net investment. Foreign Trade • Trade deficits, the result of importing more goods than exporting goods, can sometimes increase investment and capital deepening if the imports consist of investment goods rather than consumer goods.

15. Chapter 10: The U.S. Labor force

16. Labor Force, Differences in Wages and Salaries Labor force: all people not in institutions who are 16 years of age or older and who are currently employed or who are unemployed and looking for work Difference in ability. Differences in effort and jobs. Experience. Good timing.

17. The Rise of AFL and CIO • AFL: American Federation of Labor: was formed under the leadership of Samuel Gompers • Gompers introduced a policy of business unionism that concentrated union efforts on obtaining higher wages and better working conditions rather than asserting political influence • John L. Lewis: formed a rival organization CIO • CIO: Congress of Industrial Organizations • This organization joined ranks with workers from the steel, automobile, rubber, textile, and meat-packing industries GIVING RISE to the term INDUSTRIAL UNION • Industrial union: made up of both skilled and unskilled workers in a particular plant or industry

18. Labor Legislation and the Growth of the Unions • Clayton Act: made labor unions “exempt” from antitrust rules and regulations • Norris-LaGuardia Act of 1932: limited the ability of the courts to use injunctions • Injunctions: used to stop workers from striking • Fair Labor Standards Act of 1938: Minimum wage law • National Labor Relations Act of 1935: (Wagner Act): measure guaranteed the right of workers to join unions and engage in collective bargaining • Labor-Management Relations (Taft-Hartley) Act of 1947: prevented labor unions from engaging in “unfair labor practices”

19. Chapter 9: Vocabulary • GDP: Gross Domestic Product: final value of all goods and services produced within a country in a year • Nominal GDP: GDP reported in current prices • Real GDP: GDP adjusted for inflation • GDP deflator: price index that reduces current prices into prices of a base year • Real per Capita GDP: the real gross domestic product divided by the country’s population • The change is real per capita GDP is a good indicator of a change in a nation’s standard of living • It is a measure of the amount of goods and services available to a nation’s citizens

20. Vocabulary Continued… • Productivity: the output of goods and services measured per unit of input by labor, capital, land • Input: workers, capital resources, or the amount of work space used • When productivity goes UP, more or better products are produced with the same amount of resources • Labor productivity: the amount of goods and services the work force can produce during a given time period-an hour, a week, a month, a year • Increasing labor productivity is the main force behind growing per capita real GDP

21. Vocabulary Continued again… Fixed costs: costs that remain the same regardless of the amount of product a firm produces Variable costs: costs that change with the changing amounts of production Average fixed costs: total fixed costs divided by the quantity produced Average variable costs: total variable costs divided by the quantity produced Total costs: the sum of total fixed costs and total variable costs Marginal cost: additional cost of increasing a unit of production Law of diminishing marginal returns: economic principle which holds that as more and more variable resources (such as workers or materials) are added to a fixed amount of other resources (such as building and equipment), the additional (marginal) amount produced eventually decreases

22. Vocabulary continued…yet again… • Marginal revenue: the additional revenue generated from the sale of an additional quantity of the product • Total revenue: a calculation of revenue that is determined by price times quantity sold • (Total Revenue – Total Cost = Total Profit) • Marginal analysis: decision making that involves comparing marginal (additional) benefits and marginal costs • Economies of scale: reductions in cost resulting from large-scale production

23. Chapter 10: Vocabulary Derived demand: demand for a resource (such as labor) based on the demand for goods and services that the resource produces Labor force: all people not in institutions who are 16 years of age or older and who are currently employed or who are unemployed and looking for work Job discrimination: the practice of favoring one person over another for reasons that have nothing to do with ability to perform a job Labor union: an association of workers that seeks to improve its members’ wages, working conditions, and benefits Collective bargaining: a process in which union and company representatives meet to negotiate a new labor contract

24. Vocabulary continued… Strike: a withholding of labor services by a union Grievance: formal complaint made by a union if it feels one member or a class of its members have been treated inappropriately under the terms of the contract Seniority: a worker’s length of service with an employer Lockout: closing down of a business to pressure a union into accepting employment conditions Injunction: a court order to keep a union from striking and picketing Picketing: the act of employees carrying signs that call attention to a labor strike with the goal of arousing public sympathy Union shop: nonunion members can be hired by the factory, business or agency but only in the condition that they join the union after they are hired
