Study Notes

Aggregates

Aggregates are used to simplify the complex economy.
They consider the total quantity and average price of goods and services.
Helps understand the overall economic system.

Output (Y)

Aggregate output (Y) is the total quantity of goods and services demanded.
It is equivalent to the quantity in supply-demand diagrams.
Measured primarily by Gross Domestic Product (GDP).

Gross Domestic Product (GDP)

GDP measures a country's output, sales, income, and spending.
GDP is calculated as the total value of all goods produced and sold, total income earned, and total spending on goods and services.
Ideally, these measures would always yield the same result in calculation; however, this is not always the case.

Economic Growth

Growth is the change in output over time.
A recession is a decline in output lasting for two consecutive quarters.
Growth is essential for maintaining a consistent standard of living and requires substantial exponential increase.

Price Level

The average price of all goods and services is called the price level.
Equivalent to the price in supply-and-demand diagrams, it is typically measured with a basket of commonly purchased goods.

Inflation

Inflation is the rise in the general price level—meaning things are becoming more expensive.
Deflation is a fall in prices.
Disinflation is a fall in the rate of inflation.
Inflation measures the increasing cost of goods and services.

Real vs. Nominal

Real values account for changes in prices (inflation).
Nominal values are the raw data, as reported.
Nominal wages are what one earns, and real wage is the purchasing power of those earnings.
When inflation is low, nominal and real values are similar; with high inflation, the real value is significantly lower, even as a nominal wage remains constant.

Why Inflation is Bad

Erodes savings because the buying power of savings decreases.
Transfers wealth from savers to borrowers, potentially causing excessive risk-taking.
Transfers wealth from employees to employers, especially impacting those with low bargaining power.
Disrupts market mechanisms and makes the economy less efficient.
Affects wages, predominantly impacting low-wage workers.

Inflation Spiral

Inflation can be self-perpetuating.
Rising prices may lead to expectations of continued price increases, causing workers and businesses to demand higher compensation & subsequent price increases to cover those rising costs.
These mechanisms create a cycle of escalating prices.
Once an inflationary or deflationary trend starts, reversing it is often difficult and costly.

Fighting Inflation

Central banks commonly combat inflation by raising interest rates.
Rising interest rates increase borrowing costs, reducing demand and eventually curbing inflation.
Higher interest rates can, however, lead to economic slowdown or recession.

Aggregate Demand and Supply

Aggregate supply is the total value of all output produced.
Aggregate demand is the total value spent by consumers, businesses, and the government on goods and services.
Equilibrium exists where aggregate supply and aggregate demand intersect.
Equilibrium output is equivalent to the GDP, and the equilibrium price level is measured using the market basket of goods.

Factors Affecting Inflation and Growth

Changes in aggregate supply and demand cause shifts in prices and output.
Decreased aggregate supply reduces output and raises prices, i.e., recessionary pressures.
Increased aggregate demand increases prices and output (boom conditions)

Supply-Side Policies

Designed to increase aggregate supply (output).
Includes measures such as tax cuts, deregulation, labor market reforms, funding for education/training, infrastructure, and research/development, and trade liberalization.

Problems with Supply-Side Policies

Frequently have distributional consequences, potentially affecting different groups differently.
Implementation is often difficult and takes time.

Aggregate Demand Policies

Used to manage the overall demand in an economy.
Contractionary policies are used to lower inflation. Expansionary policies are used to reduce problems of economic recessions.

Fiscal Policy

Government spending and taxation policies.
Contractionary fiscal policies reduce demand; expansionary policies stimulate demand.

Monetary Policy

Central bank actions to adjust interest rates to influence the money supply.
Open Market Operations (OMOs) involve buying or selling government bonds to affect interest rates.
Higher interest rates reduce aggregate demand.
Lower interest rates increase aggregate demand.

Taylor Rule

A guideline for central banks to set interest rates based on inflation and output goals.

Central Bank Credibility

A central bank's reputation for fighting inflation is crucial in managing expectations.
A strong reputation can make inflation more manageable.
