Macroeconomic Indicators What They Are & How to Use Them Chapter 19, 20, 35

Why should financial analysts care about macroeconomics Macroeconomy can affect your career! A recent study of Stanford MBA’s between 1968 and 1997 found that the state of the national economy at the time of graduation affected the average salary up to 20 years later (plus or minus about 10%).

Other Connections Macroeconomists study government fiscal policy. Government major borrower (or saver) in financial markets. Values of financial assets a major determinants of decisions of consumers. Financial theory emphasizes diversified portfolios whose performance depends on aggregate performance of the economy.

Quantity Aggregates To understand the macroeconomy, we need to measure it. Chief measure of economy is the level of production We need to combine the many goods produced or consumed in an economy into one measure =?

Gross Domestic Product (GDP) GDP is the sum of the value of new, final goods produced within the domestic borders of an economy. All goods sold in an economy share a common unit of measure: the price at which they are sold. Final goods are goods sold to their end-users Sum up the value of goods

GDP does not include: Intermediate goods which are sold from one firm to another for immediate transformation into other goods. financial transactions like buying stocks. purchases of used goods which have been sold before. goods produced overseas by domestic firms.

Data The U.N. maintains an easy to use statistical database with annual data for a wide variety of countries UN Main Aggregates DatabaseUN Main Aggregates Database Quarterly GDP data usually available from national statistical agencies. –HK: Census & Statistics Department NIPA TablesNIPA Tables –USA: Federal Reserve St. Louis FREDFRED

Three Methods for Calculating GDP 1.Production Method - The value added created in all the sectors of the economy. 2.Expenditure Method - The sum of the domestic spending on final goods (less domestic demand satisfied by imports). 3.Income Method – The Wage, Rent, Interest and Profit Income generated by the domestic economy.

Production Method At the plant level, Value added = Sales + Change in inventories - materials, intermediate inputs and energy costs. Value added at the firm level is directly taxed in the EU (VAT) GDP is the sum of VA across establishments. The value of a final good is equal to the value added at each stage of production.

Income Method Survey domestic residents and calculate their wage income, interest income, rental income plus the income of proprietors of small firms plus the profits & depreciation of the corporate sector. –Subtract net international income flows.

Earnings or Income Approach to Measuring GDP Measuring overall economic activity by adding the earnings or income generated by selling the output produced in the economy. (Not calculated for HK on an annual basis.) GDP = compensation of employees + proprietor’s income + rental income + corporate profits + net interest Copyright © 2010 Pearson Education, Inc.

National Income Compensation of employees: the wages and salaries and the fringe benefits paid by employers to employees. Proprietors’ income: the income of unincorporated businesses, such as medical practices, law firms, small farms, and retail stores. Rental income : the income households receive from the rental of their property. Corporate profits: the excess of revenues over costs for the incorporated business sector of the economy. Net interest: the interest private businesses pay to households for lending money to the firms minus the interest businesses receive plus interest earned from foreigners.

High Concept Income = Expenditure = Value Added

High Concept Value of a final good expenditure is equal to value added at each stage of production. (Expenditure = Value Added) Value Added would be paid to workers, creditors, or kept as profits. (Income = Value Added)

GNP vs. GDP Net Factor Income [NFI] is income earned on overseas work or investments minus income generated domestically but paid to foreigners. GNPGDP Gross National ProductGross Domestic Product = income earned by domestic residents = income created within national borders. GNP = GDP +NFI

Compare Macau and the Philippines GDP or GNP Macau produces a lot of profits paid to overseas owners of casinos. Philippines workers earn a lot of income overseas. Which is larger Philippines’ GDP or Philippines GNP? Does Macau have greater GDP or GNP?

Comparing GDP levels across time GDP measures the value of the goods produced by an economy by using the market price of each good to assign it a value. Problem: Prices of goods in terms of money are changing overtime making comparisons in overall value difficult. –Bias: Money prices are growing over time as money supply grows. Solution: Choose a Base Year’s prices as a fixed yardstick of value for different goods.

Real GDP: Y t GDP aka Nominal GDP aka Current Dollar GDP is the weighted sum of the number of goods produced using their current prices as the weight. Real GDP aka Constant Dollar GDP aka GDP adjusted for inflation is the weighted sum of the number of goods produces using the Base Year prices as yardsticks.

Price Indices: P t Two most commonly used price indices are GDP Deflator and Consumer Price Index (CPI) The GDP deflator is the ratio of nominal GDP to Real GDP (multiplied by 100).

Consumer Price Index The CPI is the price of a representative market basket of goods relative to the price of that same basket during a benchmark/base year (multiplied by 100).

Hong Kong’s History of Prices

Q: What is Inflation? A: The Growth Rate of Price Level Inflation: prices are growing Disinflation: inflation is slowing down but still positive Deflation: inflation is negative and prices are actually dropping.

Example What is the inflation rate in Candyland in 2005?

Adjusting for Inflation We can use some price index to “adjust for inflation” effectively converting a variable measured in money (nominal into a variable measured in the prices of some reference year. Real series measures the value of goods that could have been purchased with that amount of money in the reference year.

Converting Current Price Series into Constant Price Series Series to be adjusted for inflation: N t Contemporaneous price level (P t ) and comparable price level in reference year (P Ref ) Series adjusted for inflation – (i.e. how much that the goods that you could have bought with N in year t would cost in year Ref.)

Housing Price: Hong Kong Island Compare the price of housing in HK average price of an apartment on HK Island with an area between 100m 2 and 160m 2 –in September 2009 : HK$173,762 /m 2 –in December 1982: HK$14,742/m 2 How much did an apartment cost back then when expressed in today’s dollars?

Housing Price: Hong Kong Island The Hong Kong CPI (2000=100) was 35.5 in December 1982 and in December Calculate: In real terms, luxury housing in 2009 is almost 3 times as expensive as in 1982!

Example Compare the box office take of “Shrek 2” and “Sound of Music” in 2004 dollars.

Learning Outcomes Students should be able to: Calculate simple real aggregates like real GDP. Use price indices to calculate inflation rates and real interest rates. Adjust nominal series for inflation.
