Modern Monetary Theory vs Mainstream Monetary Theory

Although not in the A2 syllabus we have had some great discussions in my A2 class on Modern Monetary Theory – MMT. It has its roots in the theory of John Maynard Keynes who during the Great Depression created the field of macroeconomics. He stated that the fact that income must always move to the level where the flows of saving and investment are equal leads to one of the most important paradoxes in economics – the paradox of thrift. Keynes explains how, under certain circumstances, an attempt to increase savings may lead to a fall in total savings. Any attempt to save more which is not matched by an equal willingness to invest more will create a deficiency in demand – leakages (savings) will exceed injections (investment) and income will fall to a new equilibrium. When you get this situation it is the government that can get the economy moving again by putting money in people’s pockets.

MMT states that a government that can create its own money therefore:

1. Cannot default on debt denominated in its own currency;
2. Can pay for goods, services, and financial assets without a need to collect money in the form of taxes or debt issuance in advance of such purchases;
3. Is limited in its money creation and purchases by inflation, which accelerates once the economic resources (i.e., labor and capital) of the economy are utilised at full employment;
4. Can control inflation by taxation and bond issuance, which remove excess money from circulation, although the political will to do so may not always exist;
5. Does not need to compete with the private sector for scarce savings by issuing bonds.

Within this model the only constraint on spending is inflation, which can break out if the public and private sectors spend too much at the same time. As long as there are enough workers and equipment to meet growing demand without igniting inflation, the government can spend what it needs to maintain employment and achieve goals such as halting climate change.

How does it differ from more mainstream monetary policy – see table below.

Those against MMT are dubious of the idea that the treasury and central bank should work together and also concerned about the jobs guarantee. They argue that if the government’s wage for guaranteed jobs is too low it won’t do much to help unemployed workers or the economy, while if it’s too high it will undermine private employment. They also say that trying to use fiscal policy to steer the economy is a proven failure because politicians rarely act quickly enough to respond to a downturn. They can’t be relied upon to impose pain on the public through higher taxes or lower spending to quell rising inflation.

A2 Economics – Liquidity Trap

Just covering this with my A2 class and have gone through the theory with them. The liquidity trap is a situation where monetary policy becomes ineffective. Cutting the rate of interest is supposed to be the escape route from economic recession: boosting the money supply, increasing demand and thus reducing unemployment. But John Maynard Keynes argued that sometimes cutting the rate of interest, even to zero, would not help. People, banks and firms could become so risk averse that they preferred the liquidity of cash to offering credit or using the credit that is on offer. In such circumstances, the economy would be trapped in recession, despite the best efforts of monetary policy makers.

The graph below shows a liquidity trap. Increases or decreases in the supply of money at an interest rate of X do not affect interest rates, as all wealth-holders believe interest rates have reached the floor. All increases in money supply are simply taken up in idle balances. Since interest rates do not alter, the level of expenditure in the economy is not affected. Hence, monetary policy in this situation is ineffective.

Policies to overcome a liquidity trap

Quantitative easing (QE) is a type of monetary policy used by central banks to stimulate the economy when standard monetary policy has become ineffective. Governments and central banks like there to be “just enough” growth in an economy – not too much that could lead to inflation getting out of control, but not too little that there is stagnation. Their aim is the so-called “Goldilocks economy” – not too hot, but not too cold. One of the main tools they have to control growth is raising or lowering interest rates. Lower interest rates encourage people or companies to spend money, rather than save.

But when interest rates are almost at zero, central banks need to adopt different tactics – such as pumping money directly into the economy. This process is known as quantitative easing or QE.

Helicopter Drop. Milton Friedman  advocated bypassing the commercial banks and money could be paid directly to consumers . This policy was termed a ‘helicopter drop’ to indicate the idea of a central bank dropping money from a helicopter. If deflation is a real problem, the Central bank could give money credits which have to be spent by a certain date – to stop people just saving the extra money.

Turkey’s economy – stuffed

Inflation at 25%, Central Bank interest rates at 24%, Lira down 30% in value since the start of the year. What hope is there for the Turkish economy?

Wages and salaries haven’t kept pace with inflation and the reduction in demand has led to higher unemployment. There is pressure on the central bank to keep interest rates to avoid the lira collapsing. However this makes it expensive for businesses to borrow money and thereby reducing investment and ultimately growth.

No pain no gain – there is no alternative for Turkey other than undertaking painful and unpopular economic reforms. Remember what Reagan said in the 1980’s “If not now, when? If not us, who?”  He was referring to the stagflation conditions in the US economy at the time and how spending your way out of a recession, which had been the previous administration’s policy, didn’t work.

In order to the economy back on track things will need to get worse but President Erdogan has the time on his hands as there is neither parliamentary nor presidential elections in the next five years. This longer period should allow him the time to make painful adjustments without the pressure of elections which usually mean more short-term policies for political gain. Beyond stabilising the lira, which helped to ease the dollar-debt burden weighing on the country’s banks and corporate sectors, the 24 per cent interest rate level the central bank imposed also brought about a long-overdue economic adjustment. A cut in interest rates discourage net inflows of investment from foreigners and the resulting depreciation would accelerate the concerns about financial stability and deteriorating business and consumer confidence. Below is a mind map as to why a rise in the exchange rate maybe useful in reducing inflation.

RNBZ can’t seriously be thinking about reducing the OCR

Today’s labour market data showed a drop in unemployment from 4.4% to 3.9% and an employment rate of 68.3% the highest since the HLFS survey was first reported in 1986. The
unemployment rate of 3.9% is the lowest since June 2008 and towards the lowest bound of the RBNZs estimated 4% to 5.5% range for the Non-Accelerating Inflation Rate of Unemployment (NAIRU). See graph below:

Tomorrow the RBNZ present their November Monetary Policy Statement (MPS) and these figures give them limited time to change any policy direction. Remember that the RBNZ is now tasked “supporting maximum sustainable employment within the economy” alongside its price stability mandate of 1-3% CPI with a target of 2%. However these figures seem to suggest that further easing is not required to meet employment objectives.

What is the Natural Rate of Unemployment?

The natural rate of unemployment is the difference between those who would like a job at the current wage rate – and those who are willing and able to take a job. In the above diagram, it is the level (Q2-Q1).

The natural rate of unemployment will therefore include:
Frictional unemployment – those people in-between jobs
Structural unemployment – those people that don’t have the skills that fit the jobs that are available.

It is also referred to as the Non-Accelerating Inflation Rate of Unemployment (NAIRU) – the job market neither pushes up inflation nor holds it back.

Questions about the next recession.

Ryan Avent of ‘The Economist’ considers how the next recession might happen — he asks the following questions:

  1. When will the next recession be?
  2. Where will it begin?
  3. Is the world prepared for a recession?
  4. What are the obstacles?
  5. What should governments do?

Very good viewing for macro policies – Unit 4 and 5 of the CIE A2 Economics course.

With the downturn in an economy, cutting interest rates has been the favoured policy of central banks. But the use of quantitative easing (QE) might mean the end of conventional monetary policy with rates already at record low levels – by pushing rates into negative territory they are actually encouraging a deflationary environment, stronger currencies and slower growth. The graph below shows a liquidity trap. Increases or decreases in the supply of money at an interest rate of X do not affect interest rates, as all wealth-holders believe interest rates have reached the floor. All increases in money supply are simply taken up in idle balances. Since interest rates do not alter, the level of expenditure in the economy is not affected. Hence, monetary policy in this situation is ineffective.

Economic Consequences of Trump

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’.

Global Monetary Policy – why are US rates on the rise?

With the A2 mock exam next week here is a post on the theory and applied aspects of monetary policy. Monetary policy is the process by which the monetary authority of a country controls the supply of money, often targeting an inflation rate or interest rate to ensure price stability and general trust in the currency.

Further goals of a monetary policy are usually to contribute to economic growth and stability, to lower unemployment, and to maintain predictable exchange rates with other currencies.

Monetary policy is referred to as either being expansionary or contractionary, where an expansionary policy increases the total supply of money in the economy more rapidly than usual, and contractionary policy expands the money supply more slowly than usual or even shrinks it. Expansionary policy is traditionally used to try to combat unemployment in a recession by lowering interest rates in the hope that easy credit will entice businesses into expanding. Contractionary policy is intended to slow inflation in order to avoid the resulting distortions and deterioration of asset values. See  mind map of Monetary Policy below.

What have caused US interest rates to increase?

The US economy has been at the forefront of the global upswing in the last couple of years and compared to other countries they are imposing a contractionary monetary policy – see graph.

The central bank in the USA, the Federal Reserve, are confident that the economy is nearly at full capacity and that inflationary pressures are starting to become evident. The main factors behind this are as follows and they all point towards an increase in aggregate demand.

  • Higher GDP growth
  • Rising investment in oil and gas industry
  • Strong consumer spending
  • Tax cuts
  • Strong employment growth
  • Tight labour market
  • Higher wages

The US is the only major economy to impose a significant contractionary monetary policy and the Fed has increased its interest rate six times in the last two years, and four more rate hikes are expected over the next 12 months. The UK and Canada have raised their policy rates tentatively, while Europe and Japan are still in the midst of unconventional easing programmes and interest rate hikes are a distant prospect. Whilst the Reserve Bank in New Zealand don’t expect rates to rise until early 2020.

New Zealand’s Neutral Rate of Interest

A speech delivered last July by John McDermott (Assistant Governor and Head of Economics at the RBNZ) talked about the neutral rate of interest. Central Banks have often used the term ‘the neutral rate’ which refers to a rate of interest that neither stimulates the economy nor restrains economic growth. This rate is often defined as the rate which is consistent with full employment, trend growth, and stable prices – an economy where neither expansionary nor contractionary measures need to be implemented.

The neutral interest rate is the rate of interest where desired savings equal desired investment, and can be thought of as the level of the OCR that is neither contractionary nor expansionary for the economy.

OCR > Neutral Rate = Contractionary and slowing down the economy
OCR < Neutral Rate = Expansionary and speeding up the economy

The RBNZ’s last published estimate of the neutral OCR was in June 2017 at 3.5%, with a range of estimates around that between 2.6% to 4.6%. Like many other countries, the neutral cash rate in NZ is estimated to have been declining over many years.

Since the GFC neutral rates around the world have been falling which reflects the following:

  1.  Lower expectations about growth in the economy = reduces the return to investment
  2.  Relative to pre-GFC, a wider spread between the central bank rate and the interest rates faced by households and businesses (i.e. mortgages and business lending rates).
  3. An increase in global desired savings. For instance, demographic trends offshore have led to an increase in saving among the cohort of the population going through prime earning years (as they save for retirement). Likewise, increased income inequality is thought to increase desired savings, as top income earners typically have a lower marginal propensity to consume – MPC.
  4. Higher debt ratios in some countries (including NZ) make the economy more sensitive to interest rate increases than before.

Central Banks don’t have the independence to set the neutral rate as it is very much influenced by global forces. However they do have independence as to where they set their policy rate relative to the neutral rate.
