Introduction to Macro

●The study of a whole economy

●Macroeconomic phenomenon - rise in gasoline price, income growth, job growth, price

of goods rising, etc.

●These phenomena affect everyone in the economy

●Macroeconomists try to explain these phenomenon, understand how the economy

changes over time and predict how the economy will evolve in the future

●Macroeconomists use data from the past - information of key variables that explain the

state of the economy

●They build models to predict the evolution of an economy

●Some key information that macroeconomists need to build their models

○Gross domestic product (GDP)

■Total income of everyone in the economy or the total expenditure on its

output of goods and services

○Real GDP

■When GDP is adjusted for price level of goods in the economy which

gives an idea of purchasing power of an economy

○Inflation rate

■How fast prices are rising

○Unemployment rate

■Fraction of labor force that is looking for work but is not employed

Real GDP of U.S.

●How does the Real GDP of an economy evolve over time

●Real GDP grows over time

●Real GDP per person = income of the average person in an economy

○= real GDP / total population for each year

●Does not rise continuously

●Periods when there is a dip - recession or depression depending on severity

Inflation rate in the U.S.

●Inflation rate - measures the percentage in the average level of prices from the year

before

●If inflation rate is above zero: prices are rising

●If inflation rate is above below: prices are falling

●When prices are falling, it is also called deflation

Econ 100b lecture 17 - june 07, 2018. Macroeconomic phenomenon - rise in gasoline price, income growth, job growth, price of goods rising, etc. These phenomena affect everyone in the economy. Macroeconomists try to explain these phenomenon, understand how the economy changes over time and predict how the economy will evolve in the future. Macroeconomists use data from the past - information of key variables that explain the state of the economy. They build models to predict the evolution of an economy. Some key information that macroeconomists need to build their models. Total income of everyone in the economy or the total expenditure on its output of goods and services. When gdp is adjusted for price level of goods in the economy which gives an idea of purchasing power of an economy. Fraction of labor force that is looking for work but is not employed. How does the real gdp of an economy evolve over time.

There are many economic models to explain the macro-economies function. Adam Smith started the classic economic thinking with his laissez-faire theory. The classical foundation for the role of money supply in an economy started in the mid-1700s. In classic macroeconomics, money is used for transactions. If there is more money or less money in circulation then it means that the prices are higher or lower. The classic model dominated microeconomics and macroeconomics of 1800 and 1900. In the classic macroeconomic model, the role of money is that it is used for transactions. The classic role of money can be understood through the quantity theory of money. The quantity theory of money states that if there are changes in the price level, then there will be corresponding changes in the money supply. The equation for the quantity theory of money is: M * V = P * Q

In this equation,

M = Nominal money supply

V = Velocity of money

P = Average price level

Q = Quantity of goods and services sold

The average price times quantity of goods and services sold represents the nominal GDP. The velocity of money is the number of times a currency is spent during a year.

Say's Law states that supply creates its own demand. It means that the income that is derived from producing some goods by an individual, allows him to purchase goods produced by some other individual. Since everyone has a need to purchase goods, they will produce some goods to earn income and buy what they want. So, the product markets will always be in equilibrium.

Show an empirical study that tests the relative inflation and growth rates on the nominal exchange rates.
