Q

What are the 3 reasons as to why the unemployment rate is not a perfect measure?

A
  1. It is difficult to distinguish between a person who is not in the labor force and someone who is unemployed.
  2. There are discouraged workers - people who would like to work but have given up in looking for a job, do not show up in unemployment statistics
  3. other people may claim to be unemployed to receive financial assistance, even though they are not looking for work.

Q

Describe the adjustment process after an injection of money into the economy i.e inflation:

A

An increase of money supply to an economy in equilibrium means that the quantity of money supplied is larger than the quantity demanded. Individuals no hold more money than they desire. This will increase consumption to compensate. The economy’s ability to produce goods and services has not been altered by the increase in money supply. The excess demand for goods and services means prices must rise. People then demand more money as they require more to consume at the new level. Eventually money demand will equal money supply and the economy will be in equilibrium. The price level acts to bring the supply and demand for money into equilibrium.

  • the quantity of output must rise (output not affected by money supply because need more land labour etc)

therefore prices rise due to inflation

Q

What is hyperinflation and why does it occur?

A

It is inflation that exceeds 50% per month. It occurs in some countries because the government prints too much money to pay for its spending.

Q

Describe an inflation tax:

A

When the government raises revenue by printing money it is said to levy an inflation tax. An inflation tax is like a tax on everyone who holds money. The inflation ends when the government institutes fiscal reforms such as cuts in government spending.

Q

Describe the cost of inflation: shoe leather costs

A

these are the wasted resources when inflation encourages people to reduce their money holdings. Inflation reduces the real value of money so people have incentive to minimise other cash holdings. Less cash requires more frequent trips to the bank to withdraw money from interest bearing accounts. The actual cost of reducing your money holdings is the time and convenience you must sacrifice to keep less money on hand. Extra trips to the bank take time away from productive activities.

103
Q

Describe the cost of inflation: menu costs

A

they are the costs of adjusting prices. During inflationary times it is necessary to update price lists and other posted prices. This is a resource-consuming process that takes time away from other productive activities.

104
Q

Describe the cost of inflation: relative price variability and the misallocation of resources

A

inflation distorts relative prices. Consumer decisions are distorted and markets are less able to allocate resources to their best uses.

105
Q

Describe the cost of inflation: inflation induced tax distortions

A

Inflation exaggerates the size of capital gains and increases the tax burden on this type of income. With progressive taxation, capital gains are taxed more heavily.

106
Q

What is bracket creep?

A

When there is inflation, wages are adjusted to the same level, however this means that sometimes you are moved to a higher tax bracket meaning you must pay more tax.

107
Q

Describe the cost of inflation: confusion and inconvenience

A

When the RBNZ increases money supply and creates inflation, it erodes the real value of the unit of account. Inflation causes dollars at different times to have different real values. therefore with rising prices, it is more difficult to compare real revenues, costs and profits over time.

108
Q

Q

If there is a deficit of the current account, how is this matched by the capital account?

A

By a surplus

133
Q

What does a surplus in the capital account indicate?

A

That NZ’s current account is being financed from the savings of foreigners which is bad because they will take the profit back to their own country, not NZ. It comprises foreign direct investments and foreign portfolio investments.

134

Q

When would there be inflows relating to NZ investment overseas rise/fall?

A

When overseas economic conditions are buoyant/depressed

140
Q

Describe NZ’s biggest problem - persistent large deficit in the current account is a major factor in the large invisible deficit:

A

reflects NZ’s heavy independence over long periods on foreign investment and overseas borrowing to finance current account deficits

141
Q

What are the 2 main causes of the external debt in NZ - the deficit in the current account?

A
  1. rising overseas claims (including external debt) caused by persistent current account deficits
  2. ready availability of overseas capital has encouraged national “overspending” i.e living beyond our means
142

A

when domestic residents buy foreign assets

145
Q

A
  1. provides an additional source of capital for economic development
  2. access to markets through integration in international production networks - complements liberalisation of trade
  3. access to technology
146
Q

A
  1. Bring national expenditure more in line with national earnings (accept a lower standard of living)
  2. increase the proportion of domestic investment financed from domestic saving.
147
Q

A

the price at which one currency exchanges for another

151
Q

What is the trade weighted index?

A

it is an alternative to quoting the price of NZ$ in terms of individual foreign currencies. It measures the value of the NZ$ in terms of weighted average of currencies of major trading partners. The weightings are loosely based on importance in overseas trade transactions. It provides a more balanced measure of value of NZ$ over time.

152
Q

Describe the demand curve for NZ$:

A
  • slopes down to the right

- demand for NZ$ = supply of foreign currency

153
Q

Describe the supply curve for NZ$:

A
  • slopes up to left

- supply of NZ$ = demand for foreign currency

154
Q

What are the 2 types of exchange rates?

A

fixed and floating/free

  3. Terms of trade shock
  4. relative inflation rates
  5. relative prosperity of our trading partners
160
Q

Describe relative rates of interest:

A

Demand for NZ$ rises, so supply falls and equilibrium price rises. equilibrium NZ$ price will fall if NZ interest rates fall relative to foreign rates. we can raise interest rates to stop exchange rate falling or lower interest rates to encourage the exchange rate to fall.

161
Q

Describe terms of trade shock:

A
  • sudden rise in import prices - supply of NZ$ rises and equilibrium exchange rate falls
  • sudden collapse of export prices - demand for NZ$ falls and equilibrium exchange rate falls
162
Q

What are the 2 most important international prices?

A

the nominal exchange rate and the real exchange rate

163
Q

What is the nominal exchange rate?

A

the rate at which a person can trade the currency of one country to the currency of another. it can be expressed in 2 ways:

  1. in units of foreign currency per one NZ dollar
  2. in NZ dollars per one unit of the foreign currency
164
Q

What is the real exchange rate?

A

A measure of international competitiveness and of relative purchasing power. Adjusts the nominal exchange rate for any inflation differential between trading partners. The real exchange rate is the rate at which a country trades its goods and services with another country. It compares the prices of domestic goods and foreign goods in the domestic economy.

165
Q

What units is the real exchange rate measured in?

A

Units of the foreign item per unit of the domestic item

166
Q

What is the real exchange rate equation?

A

= (nominal exchange rate x domestic price - in domestic currency) ÷ foreign price (in foreign currency)

167
Q

If there is inflation, how does it affect the competitiveness of NZ and the real exchange rate?

A

NZ competitiveness falls and he real exchange rate rises. It can be fixed with the depreciation of NZ$

168
Q

When does the real exchange rate rise i.e NZ loses competitiveness?

A

NZ inflation exceeds trading partners inflation and nominal exchange rate rises (NZ$ appreciates)

169
Q

When does the real exchange rate fall i.e NZ gains competitiveness?

A

NZ inflation is lower than trading partners inflation and nominal exchange rate falls (NZ$ depreciates)

170
Q

What is the key determinant of how much a country imports/exports?

A

the real exchange rate

171
Q

What is the PPP (purchasing power parity) theory?

A

a unit of any given currency should be able to buy the same quantity of goods in all countries

172
Q

What is the law of one price?

A

a good must sell for the same price in all locations

173
Q

What is arbitrage?

A

the process of taking advantage of differences in prices in different markets. eventually prices that differed in two markets would necessarily converge

174
Q

If the purchasing power is always the same at home and overseas, what would happen to the nominal exchange rates?

A

the nominal exchange rate can’t change and it will be 1

175
Q

What are the limitations of purchasing power parity?

A
  • many goods are not easily traded or shipped from one country to another
  • tradable goods are not always perfect substitutes when they are produced in different countries
176
Q

in a large open economy, describe government budget deficits:

A
  • reduce national saving and hence the supply of loanable funds
  • drive up interest rate
  • crowd out domestic investments
  • cause net capital outflow to fall (i.e NZ investment overseas decreases and foreign investment in NZ increases)
177
Q

What is the effect of budget deficits on loanable funds?

A

decreases the supply i.e shifts to the left which raises interest rate

178
Q

how do government deficits affect net capital outflow?

A

higher interest rates reduce capital outflow so NZ investors cut back their purchase of foreign capital and foreign investors buy the NZ$ denominated bonds and other assets which yield a higher interest rate

179
Q

How do government deficits affect foreign currency exchange rates?

A

a decrease in net capital outflow reduces the supply of NZ dollars in the international market. This causes the real exchange rate to appreciate and the CAB (current account) to deteriorate

180
Q

What are the twin deficits?

A

Higher rate of interest will result in overseas people buying NZ bonds which increases the demand for NZ$ so the NZ$ appreciates. exports are reduced and imports increase so net exports are down which leads to a trade deficit (twin deficits)

181
Q

describe the effect of government deficits on a small open economy e.g NZ:

A

they reduce national savings however its effect on supply of loanable funds is negligible since reduction of savings is almost always offset by an increased inflow of funds from overseas, hence the interest rate does not change. there is also no crowd out of domestic investments
S (decreases) = I + NCO (decreases)

182
Q

What is a trade policy and what are 3 examples?

A

Trade policies are government policy hat directly influences the quantity of goods and services that a country imports or exports

  1. Tariff - a tax on an imported good
  2. Import quota - a limit on the quantity of a good produced overseas and sold domestically
  3. Export subsidy - cash payments to exporters per unit of export
183
Q

describe how trade policies affect the NCO or CAB:

A

they don’t because they don’t change national savings or domestic investments. For a given level of national savings and domestic investments, the real exchange rate adjusts to keep the trade balance the same. more affects microeconomic rather than macroeconomic - only helps 1 industry

184
Q

What are the effects of promoting trade?

A
  1. no change in interest rate because nothing happens in the loanable funds market
  2. no change in NE and the CAB
185
Q

What is capital flight?

A

a large and sudden reduction in the demand for assets located in a country

186
Q

What is the affect of capital flight?

A

interest rate increases and domestic currency depreciates

187
Q

What is a recession?

A

a period of declining real incomes and rising unemployment - insufficient demand

188
Q

What is a depression?

A

A severe recession

189
Q

Describe the economic fact - most macroeconomic variable fluctuate together

A

Most macroeconomic variables that measure some type of income or production fluctuates closely together. Although they fluctuate together, they fluctuate by different amounts

190
Q

changes in GDP are ______ related to changes in the unemployment rate

A

inversely

191
Q

In the eqn involving G, what does G depend on?

A

it is a fixed policy variable of government fiscal policy whereas the other 3 variables depend on economic conditions i.e the price level

192
Q

describe the economic fact: net exports and output tend to move in the opposite direction

A

output has a weak negative correlation with changes in net exports. when GDP declines net exports increase. the relationship depends on what caused the GDP change

193
Q

What are the 4 key facts about economic fluctuations?

A
  1. Economic fluctuations are irregular and unpredictable
  2. Most macroeconomic variables fluctuate together
  3. As output falls, unemployment rises
  4. Net exports and output tend to move in the opposite direction
194
Q

We cannot use the classical theory of economics to describe economics in the short run, therefor what doe we use instead?

A

the model of aggregate demand and aggregate supply.

195
Q

What is the eqn for aggregate demand?

A

AD = C + I + G + NX

196
Q

What are the 2 variables that make up the model of aggregate demand and supply?

A
  1. the economy’s output of goods and services measured by the real GDP. The overall price level measured by the CPI or GDP deflator
197
Q

What does the aggregate demand curve show?

A

the quantity of goods and services that households, firms, and the government want to buy at each level

198
Q

What does the aggregate supply curve show?

A

the quantity of goods and services that households, firms, and the government choose to produce and sell at each price level

199
Q

Why does the demand curve slope downwards i.e what are the 3 theories?

A
  1. the price level and consumption - the wealth affect
  2. the price level and investment - the interest rate effect
  3. the price level and net exports - the exchange rat effect
200
Q

describe the price level and consumption - the wealth affect

A

a decrease in the price level makes the consumer feel more wealthy which in turn encourages them to spend more. This increase in consumer spending means that larger quantities of goods and services are demanded (affect C) - the pigou effect

201
Q

describe the price level and investment - the interest rate effect

A

a lower price level decreases the interest rate which encourages greater spending on investment goods. this increase in investment spending means a larger quantity of goods and services demanded (affects I) - the keynes effect

202
Q

describe the price level and net exports - the exchange rat effect

A

when a fall in the NZ price level (less inflation) causes NZ interest rates to fall, the real exchange rate depreciates which stimulates NZ net exports. the increase in NE spending means a larger quantity of goods and services demanded (NX) - the mundell-flemming effect

203
Q

What are the 4 things that cause a shift in the AD curve?

A

changes in:

  • consumption
  • investment
  • government purchases
  • net exports
204
Q

Describe the shifts of the AD curve arising from consumption:

A
  1. If NZ become more concerned with saving for retirement and reduce current consumption, aggregate demand will decline
  2. If the government cuts taxes, it encourages people to spend more resulting in an increase in aggregate demand
205
Q

Describe the shifts of the AD curve arising from investment:

A
  1. If firms become pessimistic about future business conditions, they may cut back on investment spending shifting aggregate demand to the left
  2. An investment tax credit increases the quantity of investment goods that firms demand which results in an increase in aggregate demand
  3. An increase in the supply of money lowers the interest rate in the short run. This leads to more investment spending which causes an increase in aggregate demand
206
Q

Describe the shifts of the AD curve arising from government purchases

A

If the NZ government decides to reduce purchases of construction materials for building new roads, aggregate demand will fall

207
Q

Describe the shifts of the AD curve arising from net exports

A
  1. When east Asia experiences a recession, it buys fewer goods and services from NZ which lowers net exports. Aggregate demand will shift to the left
  2. If the value of the NZ dollar increases, NZ goods will become more expensive to foreigners. Net exports fall and aggregate demand shifts to the left
208
Q

In the long run, the aggregate supply curve is _____

in the short run, the aggregate supply curve is ______

A

vertical

upward sloping

209
Q

Why is the long run supply curve vertical?

A

In the long run, an economy’s production of and services depends on its supplies of labour, capital and natural resources and on the available technology used to turn these factors of production into goods and services. The price level does not affect variables in the long run

210
Q

In the vertical supply curve, the level of production is often called?

A

the natural rate of output or potential output (Yp) or full-employment output (Yfe) - when the economy is working at full capacity

211
Q

Is the vertical aggregate supply curve an application of the classical theory of economics?

A

Yes, it is an application of the classical dichotomy and monetary neutrality

212
Q

describe the effect of price level on aggregate supply of one product - i.e ice cream (microeconomics)

A

The upward sloping curve as more resources can be diverted to increase supply, but overall production in economy cannot increase when all prices increase

213
Q

What are the 5 variables that cause shifts in the aggregate supply curve?

A
  1. labour
  2. capital
  3. natural resources
  4. technological knowledge
  5. government polices
214
Q

Describe the shifts of the AS curve arising from labour:

A

Increases in skilled worker immigrants increases the number of workers available. The ling-run aggregate supply curve would shift to the right.

215
Q

Describe the shifts of the AS curve arising from capital:

A

An increase in the economy’s capital stock raises productivity and thus shifts the long run AS curve to the right. this is true for both human and physical capital

216
Q

If the natural rate of unemployment goes down, how does this affect the LRAS curve?

A

It will shift to the right

217
Q

If minimum wage is raised, how does this affect the LRAS curve

A

it will shift to the left because unemployment levels have risen

218
Q

Describe the shifts of the AS curve arising from changes in natural resources

A
  • a discovery of a new mineral deposit increases LRAS
  • a change in weather patterns that makes farming more difficult shifts the LRAS curve to the left
  • a change in the availability of imported resources can also affect long-run aggregate supply
219
Q

Describe the shifts of the AS curve arising from technological knowledge:

A
  • the invention of the computer has allowed the production of goods and services from any given level of resource. it shifted the AS curve to the right
  • opening up international trade has also shifts the curve to the right
220
Q

Describe the shifts of the AS curve arising from government polices

A
  • economic reforms introduced in NZ in the 1980’s and the 1990’s reduced the cost of resource allocation and that led to an economy wide gain in efficiency which in turn lead to an increase in productivity and an increase in real wages followed by unprecedented growth in innovative activities by self-employed people
221
Q

What are the 3 theories as to why the short term AS curve slopes upwards?

A
  1. the sticky wage theory
  2. the sticky price theory
  3. the misperceptions theory
222
Q

Describe why the short term AS curve slopes upwards: the sticky wage theory

A

nominal wages at slow to adjust. wages do not adjust immediately to a fall in the price level. A lower price level makes employment and production less profitable. This induces firms to reduce the quantity of goods and services supplied. wages are fixed on long term contracts and when prices fall, wages are stuck, the costs of firms go up and firms will hire less labour and supply less goods and services

223
Q

Describe why the short term AS curve slopes upwards: the sticky price theory

A

prices of some goods and services adjust slowly in response to changing economic conditions due to menu costs. An unexpected fall in the price level leaves some firms with higher than desired prices. This depresses sales which induces firms to reduce the quantity of goods and services they produce

224
Q

Describe why the short term AS curve slopes upwards: misperception theory

A

changes in the overall price level temporarily mislead suppliers about what is happening in the markets in which they sell their output. A lower price level causes misperceptions about relative prices which induce suppliers to decrease the quantity of goods and services supplied

225
Q

What are the 5 variables that cause a shift in the short term AS curve?

A
  1. labour
  2. capital
  3. natural resources
  4. technology
  5. expected price level
226
Q

Why might the short term AS curve shift in response to changes in the expected price levels?

A
  1. an increase in expected price level reduces the quantity of goods and services supplied and shifts the short term aggregate supply curve to the left
  2. A decrease in the expected price level raises the quantity of goods and services supplied and shift the short run aggregate supply curve to the right
227
Q

in the short run, shifts in the aggregate demand cause?

A

fluctuations in the economy’s output of goods and services

228
Q

in the long run, shifts in the aggregate demand cause?

A

affect the overall price level but not the output

229
Q

What are the 3 causes of the supply curve shifting to the left - not impacting on demand?

A
  1. output falls below the natural rate of employment
  2. unemployment rises
  3. the price level rises
230
Q

What is the result of an adverse shift in aggregate supply?

A

It causes stagflation - a period of recession and inflation. Output falls and prices rise. Policy makers who can influence aggregate demand cannot offset both these adverse effects simultaneously

231
Q

How can we fix the effects of an adverse shift in aggregate supply i.e stagflation?

A

Policy makers can respond to these changes i one of 2 ways

  1. do nothing and wait for prices and wages to adjust
  2. take action to increase aggregate demand by using monetary and fiscal policy
232
Q

Describe the money supply curve:

A

It is a variable of the central bank and does not depend on other variables or the ROI. The fixed money supply in the USA is represented by a vertical supply curve

233
Q

For the NZ economy, what are the 2 most important reasons for the downward slope of the aggregate demand curve?

A

interest rate effect and the exchange rate effect

234
Q

Describe the theory of liquid preference:

A

It is theory by Keynes that explains what factors determine the economy’s interest rate. According to the theory, interest rate adjusts to balance the supply and demand for money

235
Q

What are the 3 ways that the money supply is controlled by the central bank?

Q

What are the 2 things that determine money demand?

A
  1. According to the theory of liquidity preference one of the most important factors is the interest rate.
  2. people choose to hold money instead of other assets that offer higher rates of return because money can be used to buy goods and services
237
Q

What is the opportunity cost of holding money?

A

It is the interest that could be earned on interest earning assets. An increase in the interest rate raises the opportunity cost of holding money. As a result, the quantity of money demanded is reduced

238
Q

How can the central bank shift the demand curve by changing monetary policy?

A

An increase in money supply shifts the money supply curve to the right

239
Q

What happens when the central bank increases the money supply?

A

It lower the interest rate and increases the quantity of goods and services demanded at any given price level, shifting the aggregate demand curve to the right

240
Q

What happens when the central bank contracts the money supply?

A

It raises the interest rate and reduces the quantity of goods and services demanded at any given price level, shifting the aggregate demand curve to the right

241
Q

What is fiscal policy?

A

The governments choices regarding the overall level of government purchases or taxes (G + T)

242
Q

What does fiscal policy affect in the short run?

A

Aggregate demand

243
Q

What does fiscal policy affect in the long run?

A

Saving, investments and growth

244
Q

How do monetary policy and fiscal policy differ on the way they affect the aggregate demand curve?

A

Monetary policy (money supply) and fiscal policy (taxes) is indirect because it affects the aggregate demand curve through the decisions of firms or households (C + I). When the government alters its own purchases of goods and services it shifts the aggregate demand curve directly

245
Q

What are the 2 macroeconomic effects from the change in government purchases?

A
  1. The multiplier effect

2. The crowding out effect

246
Q

Describe the multiplier effect:

A

Each dollar spent by the government can raise the aggregate demand for goods and services by more than one dollar. Expansionary fiscal policy increases income and therefore consumer spending.

247
Q

What is the eqn for the multiplier effect?

A

Multiplier = 1/(1 - MPC)

MPC = marginal propensity to consume which is the fraction of extra income that a household consumes rather than saves
MPS = marginal propensity to save
MPC + MPC = 1

248
Q

What is the crowding out effect?

A

Fiscal policy may not affect the market as strongly as the multiplier. An increase in government purchases causes the interest rate to rise. A higher interest rate causes reduction in investment spending. The reduction in demand that occurs when a fiscal expansion raises the interest rate is called crowding out. It dampens the effects of fiscal policy on aggregate demand

249
Q

How does the crowding out effect affect the AD curve?

A

When the government increases its purchases by 20 million, the aggregate demand for goods and services could rise by more or less than 20 million depending on the relative strength of the multiplier effect and crowding out effect

250
Q

Describe what happens to the aggregate demand curve when the government cuts personal income taxes:

A

It increases the households take home pay. Households save some of this additional income and also spend some of it on consumer goods. It shifts to the right

251
Q

What determines the size of the shift in aggregate demand resulting from a tax change?

A

The multiplier and crowding out effect and also the households perceptions about the permanency of the tax change

252
Q

What are the 2 implications of the employment act?

A
  1. The government should avoid being the cause of economic fluctuations
  2. The government should respond to changes in the private economy in order to stabilise aggregate demand
253
Q

What are the implications of the RBA and FRA?

A
  1. Monetary policies would keep AD = LRAS

2. Fiscal policies would not be used to manage AD

254
Q

What are automatic stabilisers?

A

They are changes in fiscal policy that stimulate aggregate demand when economy goes into a recession without policymakers having to take any deliberate actions. It includes the tax system and some forms of government spending
