Hot dogs and hot dog buns are complements. If the price of a hot dog falls, then...

the demand for hot dog buns will increase.

The first equilibrium view is the national income equilibrium view. The second view is value of production or "value of total output."

...

The government taxes both the household sector and the business sector and so taxes are considered leakages.

...

The value of production is the total receipts of all producers.

...

(LO 1) Suppose the real GDP of an economy is $480 billion dollars and its unemployment rate is 7 percent. If the natural rate of unemployment is estimated at 5 percent, what is the value of the country's potential GDP in billions of dollars? $

$504 billion. (the GDP gap is equal to cyclical unemployment of 2% x 2.5 x actual GDP of $480 = $24 billion. Potentail GDP is equal to actual GDP of $480 + GDP gap of $24 = $504)

Some of the goods and services households buy come from foreign business sectors so this expenditure on imports is a leakage.

"Sit and Leak"

...

"Veg Injections"

...

Business receives payments for goods and services exported and that is a leakage.

...

Equilibrium is a state of balance between equal forces.

...

Examples of transfer payments are Employment Insurance payments, Canada PEnsion Plan payments and subsidies to businesses.

...

Financial intermediaries are financial institution, such as banks that act as agents between borrowers and lenders

...

If Leakage = Injections, then national income will remain unchanged.

...

If tax rates were to increase this would cause consumption spending to fall and income to continue to fall until the resulting decreases in Savings, Imports or Taxes were sufficient to bring injection and leakage back into equilibrium.

...

Injections > Leakage this causes disequilibrium.

...

LO2- Explain the concept of equilibrium and why national income can rise and fall.

...

Net tax revenue is total tax revenues minus government transfer payments.

...

Open Private Model with the Public Sector- The third pair of leakage/injections is not so simple- we must add another sector to our analysis: government.

...

Open Private Model- Putting Savings and Leakage aside for now, lets look a second pair of leakage/injection: imports and export.

...

Our first definition of national income equilibrium is: the level of income is where the total of all three leakages equals the total of all three injections.

...

49A a) $20; b) 5 percent (20/400 x 100); c) Since the GDP gap is 2 ½ times the amount of cyclical unemployment, the latter must equal 2% (5/2.5). Therefore the unemployment rate must be 8 percent (natural rate of 2% plus cyclical unemployment of 2%).

(LO 2) What are the three reasons for the downward slope of the aggregate demand curve?

51A. The aggregate demand curve is downward-sloping because of: real-balances effect which refers to the fact that a lower price level increases the value of real balances which will cause an increase in consumption; interest-rate effect which means that a lower price level will reduce interest rates and thereby causing an increase in investment; foreign-trade effect which means that a lower price level will make domestic products more competitive on world markets thus increasing exports and decreasing imports.

(LO 4) Starting from full-employment equilibrium, explain what effect an increase in aggregate demand will have on price, real GDP, and equilibrium.

52A. An increase in aggregate demand will lead to an increase in both real GDP and in the price level. As a result the economy will be above potential, full-employment GDP, i.e. an inflationary gap will exist.

(LO 4) T or F An increase in potential GDP has no effect on macroeconomic equilibrium.
