Below is a link to a very good interview with RBNZ Governor Adrian Orr on Radio NZ ‘Morning Report’ programme. Loads of good material on monetary policy – useful for discussion purposes with my A2 class today – online.
The Monetary Policy Committee decided to implement a Large Scale Asset Purchase programme (LSAP) of New Zealand government bonds. The programme will purchase $30 billion of New Zealand government bonds, across a range of maturities, in the secondary market over the next 12 months. The programme aims to provide further support to the economy, build confidence, and keep interest rates on government bonds low. The low OCR – 0.25%, lower long-term interest rates, and the fiscal stimulus recently announced together provide considerable support to the economy through this challenging period.
Currently covering Keynes vs Monetarist in the A2 course. Here is a powerpoint on the theory that I use for revision purposes. I have found that the graphs are particularly useful in explaining the theory. The powerpoint includes explanations of:
– Circular Flow and the Multiplier
– Diagrammatic Representation of Multiplier and Accelerator
– Quantity Theory of Money
– Demand for Money – Liquidity Preference
– Defaltionary and Inflationary Gap
– Extreme Monetarist and Extreme Keynesian
– Summary Table of “Keynesian and Monetarist”
– Essay Questions with suggested answers.

Three different shocks that are prevalent
Supply shock – will become more visible in the coming weeks as importers from China maybe unable to source adequate supply given widespread shutdowns across Chinese manufacturing.This loss of intermediate goods for production of final products cause a decline in revenue and consumer well-being. A good example of supply shocks were the oil crisis years of 1973 (oil prices up 400%) and 1979 (oil prices up 200%).
Demand shock – is already affecting consumer demand as travel slows, people avoid large gatherings, and consumers reduce discretionary spending. Already many sports fixtures have been cancelled which in turn hits revenue streams. With the uncertainty about job security demand in the consumer market will drop – cars, electronics, iPhones etc. Also tourism and airline industries are also exposed to the fall in demand.
Financial shock – although the supply and demand shocks will eventually subside, the global financial system is likely to have a longer-lasting impact. Long-term growth is the willingness of borrowers and lenders to invest and these decisions are influenced by: increased uncertainty regarding the global supply chain; a loss of confidence in the economy to withstand another attack; and a loss of confidence regarding the infrastructure for dealing with this and future crises.
Monetary policy is limited to what it can do with interest rates so low. Even with lower interest rates this does not tackle the problem of coronavirus – cheaper access to money won’t suddenly improve the supply chain or mean that consumers will start to spend more of their income. The RBNZ (NZ Central Bank) could instruct trading banks to be more tolerant of economic conditions.
Fiscal policy will be a much more powerful weapon – the government can help households by expanding the social safety net – extending unemployment benefit. Also the guaranteeing of employment should layoffs occur. Tourism and airline industries are being hit particularly hard. Although more of a monetary phenomenon the ‘Helicopter Drop’ could a policy tool of the government. A lot of governments already have introduced ‘shock therapy’ and unleashed significant stimulus measures:

Just completed the Keynes 45˚ line (still in the CIE A2 syllabus) with my A2 class and find this graph useful to explain it. A popular multi-choice question and usually in one part of an essay. Make sure that you are aware of the following;
1. C and S are NOT parallel
2. The income level at which Y=C is NOT the equilibrium level of Y which occurs where AMD crosses the 45˚ line.
1. OA is autonomous consumption.
2. Any consumption up to C=Y must be financed.
3. At OX1 all income is spent
4. At OB consumption = BQ and saving= PQ
5. Equilibrium level of Y shown in 2 ways
a) where AMD crosses 45˚ line
b) Planned S = Planned I – point D
Remember the following equilibriums:
2 sector – S=I
With Govt – S+T = I+G
With Govt and Trade – S+T+M = I+G+X
Below is a link to a very good interview with Corin Dann and Don Brash this morning on National Radio’s ‘Morning Report’. Former Reserve Bank Governor Don Brash says that the major Central Banks need to act together and reduce interest rates to offset the impact of Covid-19. The Central Banks he refers to are: US Fed, Bank of England, Bank of Japan and the European Central Bank. Good discussion of the impact of the NZ dollar on trade and the fact that just the past month in New Zealand, the virus may have cost as much as $300 million in lost exports to China. Worth a listen
Economists use the term Japanification as shorthand for the situation where economic growth remains stagnant even with significant monetary easing – lower interest rates and increased government spending. With interest rates already at record low levels it seems that a lot of economies are going the same way as Japan. However as discussed in the video below from the FT, Japan is a nice place to live and has a very high life expectancy. The concern for central banks is what other policy instruments do they have after really low interest rates – they are running out of ammunition. To boost growth in the USA is a lot different than in Japan according to Ben Friedman. He states that Japan does not have the problems of widening inequality and the stagnation of the middle income groups.
The question is why Japanese society seems to cope with an economy that doesn’t respond to very low interest rates and increase government spending? The FT look to Robert Pringle’s book ‘The Power of Money’ and suggest three reasons:
A significant number of developing countries are located in and around the equator which also means that they are more exposed to the extremes of climate change. As the world gets hotter these countries will suffer the most which makes their ability to advance their standard of living even harder. Temperatures in tropical climates will become far more variable and soil near the equator will dry up reducing its ability to dampen temperature swings e.g. Amazon rainforest, Congo, Indonesia etc.
The additional cost to poor countries in avoiding the damage caused by climate change is estimated to be between US$140bn – US$300bn each year on measures such as costal defences, strengthening buildings etc. This is according to the UN Environment Programme which assumes that global temperatures will be only 2°C above pre-industrial levels by the end of the century – unlikely according to The Economist. Not only are these countries suffering from climate change‑related drought, which will lead to a consequent drop in agricultural production and rise in food insecurity, but it also means higher interest payments than similar countries that are less exposed to climate change.
Climate Change = Higher risk of default = Higher Interest Payments
The V20 countries
The Vulnerable Twenty (V20) Group of Ministers of Finance of the Climate Vulnerable Forum is a dedicated cooperation initiative of economies systemically vulnerable to climate change. The call to create the V20 originated from the Climate Vulnerable Forum’s Costa Rica Action Plan (2013-2015) in a major effort to strengthen economic and financial responses to climate change. Originally 20 countries it has now expanded to 48 and the membership is mostly from poor countries that make up less than 5% of global GDP. They include the following:
Afghanistan, Bangladesh, Barbados, Bhutan, Burkina Faso, Cambodia, Colombia, Comoros, Costa Rica, Democratic Republic of the Congo, Dominican Republic, Ethiopia, Fiji, The Gambia, Ghana, Grenada, Guatemala, Haïti, Honduras, Kenya, Kiribati, Lebanon, Madagascar, Malawi, Maldives, Marshall Islands, Mongolia, Morocco, Nepal, Niger, Palau, Palestine, Papua New Guinea, Philippines, Rwanda, Saint Lucia, Samoa, Senegal, South Sudan, Sri Lanka, Sudan, Tanzania, Timor-Leste, Tunisia, Tuvalu, Vanuatu, Viet Nam and Yemen.
Research has estimated that V20 countries pay 1.2% higher than comparable countries which raises the V20’s borrowing costs by about 10% which is equivalent to an extra US$4bn each year in interest payments. It has also been estimated that of corporate debt a significant amount is held by countries who are the most at risk of climate change. This equates to 3% of total debt in more than 60,000 firms in 80 countries. These high risk countries were charged 0.83% higher interest on loans which equates to roughly a 10% premium. Therefore credit rating agencies are including climate change in their risk models and what makes it worse for developing countries is that they tend to be primary based economies which are the most susceptible to climate change. Moody’s, the credit rating agency, has suggested that of the 37 countries that are most vulnerable, farming accounts for 44% of employment on average.
For developing countries to counter the impacts of climate change sovereign parametric insurance has been prevalent. This insurance is pooled amongst countries in close proximity and makes the premium more affordable. This insurance relies on risk modeling rather than on-the-ground damage assessments to estimate the cost of disasters. Parametric insurance policies pay out automatically when certain pre-agreed conditions, such as wind speed, rainfall or modeled economic losses, meet or exceed a given threshold. Examples of areas where countries have pooled insurance are:
Like any insurance although it might be under used it does mean that countries can access money to recover and rebuild their economies – ideally with greater resilience.

With the A2 multiple choice tomorrow here is a mind map on liquidity preference. The liquidity preference or the demand for money is the sum of the transactionary, precautionary and speculative demand for money. Only the speculative demand is inversely related to interest rates. It is the speculative demand that students find difficult to understand. This is money not held for transaction purposes but in place of other financial assets, usually because they are expected to fall in price. Demand is interest elastic – i.e. is affected by changes in interest rates. Below is a mind map and some notes.
Bond prices and interest rates are inversely related – Interest Rates ↑ = Bond Prices ↓ and Interest Rates ↓ = Bond Prices ↑. If a bond has a fixed return, e.g. $10 a year. If the price of a bond is $100 this represents a 10% return. If the price of the bond is $50 this represents a 20% return, i.e. the lower the price of the bond, the greater the return.
At high rates of interest, individuals expect interest rates to fall and bond prices to rise. To benefit from the rise in bond prices individuals use their speculative balances to buy bonds. Thus when interest rates are high speculative money balances are low.
At low rates of interest, individuals expect interest rates to rise and bond prices to fall. To avoid the capital loses associated with a fall in the price of bonds individuals will sell their bonds and add to their speculative cash balances. Thus, when interest rates are low speculative money balances will be high.
In explaining the differences between internal and external balances I came across an old textbook that I used at University – Economics by David Begg. It was described as ‘The Student’s Bible” by BBC Radio 4 and I certainly do refer back to it quite regularly. Part 4 on macroeconomics has an informative diagram that shows the impact of booms and recessions on the internal and external balances.
Internal Balance – when Aggregate Demand equals Aggregate Supply (potential output). And there is full employment in the labour market. With sluggish wage and price adjustment, lower AD causes a recession. Only when AD returns to potential output is internal balance restored.
External Balance – this refers to the Current Account balance. The country is neither underspending nor overspending its foreign income. For a floating exchange rate, the total balance of payments is always zero. Since the balance of payments is the sum of the current, capital, and financial accounts, saying the current account is in balance then also implies that the sum of the capital and financial accounts are in balance.
In the diagram right the point of internal and external balance is the intersection of the two axes, with neither boom nor slump, and with neither a current account surplus nor a deficit.
The top left-hand quadrant shows a combination of a domestic slump and a current account surplus. This can be caused by a rise in desired savings or by an adoption of a tight fiscal policy and monetary policy. These reduce AD which cause both a domestic slump and a reduction in imports.
The bottom left-hand corner shows a higher real exchange rate, which makes exports less competitive, reduces export demand and raises import demand. The fall in net exports induces both a current account deficit and lower AD, leading to a domestic slump.
In a downturn a more expansionary fiscal and monetary policy can hasten the return to full employment eg. Quantitative easing, tax cuts, lower interest rates. However one could say that today it doesn’t seem to be that effective.
