The AS multiple-choice paper is coming up and here is this graphic to explain indirect taxes – a popular question. An indirect tax will have the following effects on the market:
• The supply curve shifts vertically upwards(effectively a shift to the left) by the amount of the tax(gf) per unit. The price increases but not by the full amount of the tax. This is because of the slopes of the demand and supply curves. • The consumer surplus is reduced from acp to agb. The portion gbhp of the old consumer surplus is transferred to government in the form of tax. • The producer surplus is reduced from pce to fde. The portion phdf of the old producer surplus is transferred to the government in the form of tax. • The market is no longer able to reach equilibrium, and there is a loss of allocative efficiency resulting in the deadweight lost shown by the area bcd. This represents a loss of both consumer surplus bhc and the producer surplus hcd that is removed from the market. The deadweight loss also represents a loss of welfare to an individual or group where that loss is not offset by a welfare gain to some other individual or group.
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
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.
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.
With the exam season just about to start in New Zealand I thought it appropriate to do some revision blog posts. In the CIE A2 paper there is always a macro policy question and it usually focuses on the conflicts between the different objectives. Below is a mindmap on fiscal policy that might be useful. Fiscal Policy involves the use of Government Spending and Taxation in order to influence the level of economic activity. The Government receives money through Taxation (T) and spends money through Government spending (G).
Video from CNBC looking at why central banks became independent and if it still should be the case – very informative and they use the Phillips Curve in their explanation. WIth the ongoing inflation problems in the 1970’s and 80’s it was thought that giving central banks independence of government control should be implemented. It was argued that policy makers would struggle to convince the public they were serious about containing inflation if politicians retained a say on setting interest rates. In 1989 New Zealand become the first country to introduce an independent bank with the 1989 – Reserve Bank Act. The mandate was to keep inflation between 0-2% but later changed to 1-3%.
With the GFC in 2008 it was central banks who slashed interest rates and implemented several rounds of quantitative easing to stimulate demand. However the GFC could have been prevented if central banks intervened to stop the biggest asset-bubble in history instead of focusing purely on keeping inflation low. Furthermore the European Central Bank were slow to act and the recovery was stymied. The fact that Germany is under the threat of deflation means that the ECB have cut interest into negative territory and are relaunch another round of quantitative easing – they are running out of options. Economists are focusing on fiscal stimulus – tax cuts and government spending. Therefore monetary and fiscal policy should be working together. According to Larry Elliott of The Guardian. central bank independence is a product of the neoliberal Chicago school of economics and aims to advance neoliberal interests. More specifically, workers like high employment because in those circumstances it is easier to bid up pay.
Venezuela has been in the news for sometime with its economy spiralling out of control with the inflation rate last year at 100,000% – doubling roughly once a month. The occurrence of hyperinflation in economies has become more common with governments now printing money rather than that money being backed by the amount of gold that they held – gold standard. Because the gold supply is quite inelastic, being on the gold standard would theoretically stop government overspending and keep inflation under control. The country effectively abandoned the gold standard in 1933, and completely severed the link between the dollar and gold in 1971 – this was around the time of the Vietnam War.
The more recent hyperinflation in Zimbabwe, Bolivia, Argentina etc have come about through government’s not been able to control the printing presses and succumbing to the desire to stay in power at the expense of crippling the economy. Huge fiscal deficits and excessive borrowing are the common denominator here – see flow chart below:
Hyperinflation usually happens amongst chaotic domestic conditions, whether social unrest or that country being involved in conflict – e.g. post war Germany. However as reported by The Economist hyperinflation can occur under more mundane circumstances. For instance in Bolivia’s inflation reached 60,000% which was started by a commodity boom which allowed them to borrow heavily from overseas but once resource prices tumbled there was a significant reduction in government revenue. The government under Hugo Banzer increased spending to satisfy the voters who supported them in the election and this created further inflationary pressure. In a way this is similar to the Venezuela experience with high oil prices generating significant revenue for the government but once the oil prices fell the printing presses started to work overtime. And once inflation starts to accelerate Inflationary expectations kick in and then it becomes very difficult to control. However these inflationary expectations could reflect the lack of seriousness of government policy to rectify the problem as a change of government which is focused on prices can end hyperinflation in weeks. This reflects the trust in the incoming regime and was true of Bolivia (see video below). Here the incoming government under Gonzalo (Goni) Sánchez de Lozada were serious about the ravages of inflation and to deal with it didn’t use highly sophisticated economic theory. See below:
Government spending was slashed
Price controls were scrapped
Import tariffs were cut
Government budgets were balanced.
No borrowing from the Central Bank
As Jeff Sachs – advisor to the Bolivian government – said:
“All this gradualist stuff just doesn’t work. When it really gets out of control you’ve got to stop it, like in medicine. You’ve got to take some radical steps; otherwise your patient is going to die.”
This is a good summary of economic developments to watch in 2019 – from Al Jazeera. Some of the key points are:
Protectionist policies will remain and any truce between the US and China will be short-lived.
The US is in an unsustainable boom – the fiscal stimulus will fade and this will be followed by two larger deficits – budget and external. The US is consuming far more that it is producing and it mirrors the 1980’s – Reaganomics.
China is slowing down – as well as the protectionist issues as a result of the US trade policy there are tensions between the economic system of capitalism and the political system of communism. This combination is referred to as ‘Market Socialism’. The problems are associated with: economic growth v environmental problems, rural areas v urban areas, rich v poor. China’s movement away from oil to gas which benefits Qatar but to the detriment of the Saudi economy.
The Gulf economies are taking a hit from the fall in oil prices and government budgets may have to be cut. Diversification from the dependence on oil is necessary to avoid the resource curse and with a growing youth population job creating is needed. Movement to a more knowledge-based economy and large infrastructure projects are becoming focus areas as a necessity.
Since the GFC economics has been dominated by fiscal and monetary policies to stimulate aggregate demand. Monetary policy has in particular been reinventing itself with low interest rates not being enough to stimulate demand and the introduction of numerous rounds of QE.
Other policy areas might lack the excitement of delving into the unknown but are just as important to an economy. Maintenance of a country’s infrastructure, assets and government accounts are essential to the long-term development but government’s tend to avoid them as they are not creating anything new and therefore not recognisable by voters. A new hospital, school or major road grab the headlines and inform the electorate that they have been busy putting tax payer money to good use. Maintenance lacks the glamour of innovation.
The US after the GFC did spend a lot of money on new vanity infrastructure projects but these were in sparsely populated areas. However, it was busy cities that really needed their transport infrastructure upgraded and you would think this would be a priority for governments. In the US the fraction of existing road surfaces that are too bumpy has risen from 10% in 1997 to 21% in 2018. Invariably if infrastructure is not maintained it causes significant costs for an economy and in some cases fatalities – the recent bridge collapse in Genoa, Italy. One of the issues for economists is that the typically used measure of an economy, GDP, doesn’t take into consideration the cost of wear and tear. In order to do this they must work out the lifespan of each asset and decide on its depreciation. Some are similar to light bulbs which means they work until they blow – economists refer to this as the “one hoss shay” case. This is based on a poem where it imagines a horse-drawn cart built so well that it never broke down until it eventually fell apart. victim of a “general flavour of mild decay”. Other assets are more linear in how they depreciate in that they lose the same amount each year. Japan assumes that houses lose 4% in value each year and that is why Japan’s consumption of fixed capital is high – 22% of GDP – see graph from The Economist.
Too often governments, and organisations for that matter, preserves day-to-day spending by cutting maintenance and investment. Finance ministers might invest more in maintenance if the resulting boost to public wealth became more transparent. Furthermore if all government departments had to account for all the capital tied up in their operations, they might feel obliged to be more productive with it. New Zealand seems to be the only country to update its public-sector balance-sheet every month, allowing for timely assessment of public-sector worth. So instead of impressing voters with ideas and glossy projects, being boring might actually do some good. Economists tend to be good at this.
Very good video from Project Syndicate looking at the recovery of the US economy and if it is sustainable. Also was Trump responsible for the growth or Obama? Maybe Janet Yellen and central bankers with such low interest rates for a long period of time. However if there is another downturn do governments have the tools to grow the economy again? It seems that central banks have run out of ammunition i.e. no room to cut interest rates further. There is agreement that the levels of employment are not sustainable in the future and the focus should be on assisting low wage work and help people prepare for and keep work- ‘reward work’.

Starting with a definition. In 1956 Phillip Cagan, an economist working at America’s National Bureau of Economic Research, published a seminal study of hyperinflation, which he defined as a period in which prices rise by more than 50% a month.
There seems to be common patterns when hyperinflation occurs in an economy. These include:
Fiscal pressure – cost of funding a war, increased social welfare payments, corrupt officials taking money from the budget.
Dependence of a particular resource – the resource curse. Some economies rely on exports of oil, iron ore or other resources to fund its spending. This has the effect of increasing the value of the currency and although this will make imports cheaper once the resource runs out or global prices start to drop the overvalued currency falls causing a large increase in imported prices. Furthermore governments come to depend on revenue from oil and a sudden drop in prices saw a massive drop in tax revenue – 90% of Venezuela’s revenue came from oil.
Printing money – like Bolivia in the 1980’s, Venezuela overcame their shortfall in income by printing more money. The increase in the supply of money pushes up inflation. But what makes it worse is, as the inflation rate impacts the real value of government revenue, they continue to print money to finance the budget deficit which in turn exacerbates the problem – bigger budget deficit and further inflation.
Exchange rate – at some stage the exchange rate will collapse as people lose confidence in the currency. Imports become ever increasingly expensive and feed into the inflation calculation.
Inflationary expectations – In recent years more attention has been paid to the psychological effects which rising prices have on people’s behaviour. The various groups which make up the economy, acting in their own self-interest, will actually cause inflation to rise faster than otherwise would be the case if they believe rising prices are set to continue. This is evident in Venezuela as people become accustomed to higher prices and expect them to continue which makes inflation likely to continue.Workers, who have tended to get wage rises to ‘catch up’ with previous price increases, will attempt to gain a little extra compensate them for the expected further inflation, especially if they cannot negotiate wage increases for another year. Consumers, in belief that prices will keep rising, buy now to beat the price rises, but this extra buying adds to demand pressures on prices. In a country such as New Zealand’s before the 1990’s, with the absence of competition in many sectors of the economy, this behaviour reinforces inflationary pressures. ‘Breaking the inflationary cycle’ is an important part of permanently reducing inflation. If people believe prices will remain stable, they won’t, for example, buy land and property as a speculation to protect themselves.
Hyperinflation tends to end in two ways.
The paper currency becomes so utterly worthless that it is supplanted by a hard currency. This is what happened in Zimbabwe at the end of 2008, when the American dollar took over, in effect. Prices will stabilise, but other problems emerge. The country loses control of its banking system and its industry may lose competitiveness.
The second, hyperinflation ends through a reform programme. This was very much the case in Bolivia in the 1980’s – Government spending was slashed. Price controls were scrapped. Import tariffs were cut. Government budgets were balanced. Therefore this typically involves a commitment to control the budget, a new issue of banknotes and a stabilisation of the exchange rate—ideally all backed with confidence-inspiring foreign loans. Without such reform, Venezuela’s leaders, though scornful of America, may find that its people are forced eventually to adopt its dollar anyway.
