Study Notes
- Macroeconomics is the study of the economy as a whole and addresses topical issues.
Important Issues in Macroeconomics
- Issues include causes of recessions, the effects of government stimulus, and problems in the housing market spreading to the broader economy.
- The government budget deficit affects workers, consumers, businesses, and taxpayers
- Concerns also include the causes of inflation and measures the Federal Reserve Bank can take to combat rising prices.
- Macroeconomics also considers why some countries have low incomes and policies to alleviate poverty.
- The trade deficit and its effect on a country's well-being are also key macroeconomic concerns.
Economic Indicators
- Real GDP per capita (in 2012 dollars) has been tracked in the U.S., and reflects the effect of things like war, terror attacks, crisis and pandemics.
- The U.S. inflation rate (in 2012 dollars) has been tracked to reflect changes in rates due to events like war, terror attacks, crisis and pandemics.
- The U.S. unemployment rate (percentage of labor force) has been tracked to reflect changes in rates due to events like war, terror attacks, crisis and pandemics.
Economic Models
- Economic models are simplified versions of complex realities, and can be used to:
- Show relationships between variables.
- Explain the economy's behavior.
- Devise policies to improve economic performance.
- Supply and demand model for new cars shows how events affect price/quantity.
- Assumes a competitive market where each buyer/seller is too small to affect market price.
- Variables in the model of supply and demand for new cars:
- Qd = quantity of cars buyers demand
- Qs = quantity of cars producers supply
- P = price of new cars
- Y = aggregate income
- Ps = price of steel which is used as an input
Demand and Supply Equations
- Demand Equation: Qd = D (P, Y) which shows the quantity of cars consumers demand related to the price of cars (P) and aggregate income (Y).
- General functional notation shows that variables are related.
- Specific functional form shows the precise quantitative relationship.
- An example is a demand equation like: D (P, Y) = 60 – 10P + 2Y.
- Demand curve shows the relationship between quantity demanded and price, with other things being equal.
- Supply equation: Qs = S (P, Ps)
- Supply Curve shows the relationship between quantity supplied, price (P) and the price if inputs (PS), with other things equal.
Equilibrium
- Market equilibrium is the point at which supply and demand curves intersect, determining equilibrium price and quantity.
- An increase in consumer income increases the quantity of pizza consumers demand at each price, increasing the equilibrium price and quantity.
- An increase in Ps (price of steel) reduces the quantity of pizza producers supply at each price.
- Causes an increase in the market price and reduces the quantity.
Endogenous and Exogenous Variables
- Endogenous variables are determined within the model.
- P, Qd, Qs, are endogenous variables in the model of supply and demand for cars.
- Exogenous variables are determined outside the model, taken as given.
- Y, Ps, are exogenous variables in the model of supply and demand for cars.
Multiple Models and Flexible/Sticky Prices
- Macroeconomists study aspects of the economy and use models to address problems.
- The supply-demand model of the car market, can show how a fall in aggregate income affects the price and quantity of cars.
- It cannot explain why aggregate income falls.
- Macroeconomic models examine different issues, and have varied assumptions and can use endogenous and exogenous variables.
- Market clearing is an assumption that prices are flexible and adjust to equate supply and demand.
- Many prices are sticky, so they adjust sluggishly in response to supply/demand changes
- Many labor contracts fix the nominal wage for a year or longer.
- Many magazine publishers change prices only once every 3-4 years.
- If prices are sticky and in the short run, demand may not equal supply
- Can lead to unemployment.
- May result in firms cannot always sell all the goods they produce.
- If prices are flexible (long run), markets clear, and the economy behaves very differently.
Book outline
- Introductory material (Chapters 1, 2)
- Classical theory (Chapters 3–8)
- How the economy works in the long run, when prices are flexible.
- Growth theory (Chapters 9–11)
- The standard of living and its growth rate over the very long run.
- Business cycle theory (Chapters 12–16)
- How the economy works in the short run, when prices are sticky.
- Macroeconomic theory and policy (Chapters 17-22)
- Covers macroeconomic dynamics, models of consumer behavior, theories of firms' investment decisions, stabilization policy, government debt and deficits, financial crises.
- Macroeconomics is the study of the economy as a whole, including: growth in incomes; changes in the overall level of prices; the unemployment rate. Macroeconomists attempt to explain the economy and improve its performance.
- Models with flexible prices describe the economy in the long run.
- Models with sticky prices describe the economy in the short run.
- Macroeconomic events and performance arise from many microeconomic transactions, so macroeconomics uses many of the tools of microeconomics.
