What is the economy?

A short animated video by the Reserve Bank which shows how the economy works. It also outlines the role of the Reserve Bank of New Zealand. Good for an introductory lesson.

What would happen if there was a Grexit?

July 3, 2015 Leave a comment

The Greeks vote on Sunday whether to accept a June 25 offer from the International Monetary Fund, European Union and the European Central Bank (collectively known as “the Troika”) to provide Greece with desperately needed bailout money. In exchange, the Troika demanded that Greece implement a list of tax increases, spending cuts, and economic reforms. If there is a no vote then there could be the following scenario.

Negatives
* Overnight the Greek authorities would have to circulate a new currency (most likely the Drachma)
* The Drachma would depreciate against the Euro – according to some analysts this would increase Greek debt from the current level of 175% to 230% of GDP.
* Interest rates would increase causing businesses to go bankrupt – some have indicated that this would be around 50% of businesses
* The risk of a run on the banks would mean that the monetary authorities would have to introduce controls on money flows – especially abroad.
* Social unrest would no doubt escalate in the short-term and many Greeks will leave the country (if they can afford it).
* The Greek government would find it difficult to raise funds from overseas as investors become more prudent and see Greek bonds as an even bigger risk than before.
* A devaluation will would do nothing to change Greece’s structural problems.
* The euro will lose credibility in the long run and its weaker members will be exposed to bank runs which will ultimately extinguish any chance of a recovery.

Positives
* A weaker currency would make Greek exports a lot cheaper and may resurrect the textile industry that collapsed a few years ago.
* However the biggest benefit would be the tourism industry where holidays would become very cheap relative to similar destinations in Europe.
* The Greek government could keep printing money to finance the promises made Alexis Tsipras’ government – maybe an inflationary threat.
* Interest rates would no longer be determined by the ECB and a more expansionary monetary policy could be implemented by Greek authorities to tackle the downturn.

We’ve been here before as Jeff Sachs mentioned in his piece from Project Syndicate.

Almost a century ago, at World War I’s end, John Maynard Keynes offered a warning that holds great relevance today. Then, as now, creditor countries (mainly the US) were demanding that deeply indebted countries make good on their debts. Keynes knew that a tragedy was in the making.

“Will the discontented peoples of Europe be willing for a generation to come so to order their lives that an appreciable part of their daily produce may be available to meet a foreign payment?” he asked in The Economic Consequences of the Peace. “In short, I do not believe that any of these tributes will continue to be paid, at the best, for more than a few years.”

The Greek government is right to have drawn the line. It has a responsibility to its citizens. The real choice, after all, lies not with Greece, but with Europe.

Below is a chart from Bloomberg Business explaining the outcomes.

What do the Shanghai Stock Exchange and the Yangtze River have in common?

June 15, 2015 Leave a comment

One of my A2 students alerted me to the fact that the Yangtze River and the Shanghai Stock Exchange Composite Index (SSEC) in the post GFC period are quite similar in shape. Maybe the building of the three gorges dam led to a drop in the SSEC index.

Auckland housing market like the Dublin bubble?

May 25, 2015 Leave a comment

Between 2007 and 2010 house prices in Dublin fell by 56% and had a devastating effect on the banking system in Ireland. Is there going to be a correction in the Auckland housing market of a similar ilk?

Brian Gaynor touched on this in his column in the NZ Herald on the 16th May. Today there are some similarities to the boom in Dublin house prices and that of Auckland. These included:

1. The media painted a picture of escalating house prices and a property boom
2. Purchasers queuing overnight to buy a section or a newly built house
3. Banks offering cash incentives on home loans.
4. Very low mortgage interest rates
5. Auckland’s house prices have increased by 12.4% in the last 6 months. By comparison Dublin’s house prices never increased by more than 12% in any six month period during the boom.
6. Mortgage debt in New Zealand is now above $200 billion – doubling in 10 years. The majority of the debt being in the Auckland residential region. Consumer mortgage debt to disposable income in 2012 was 147% as compared to 58% in  March 1991. In Ireland Bank lending it was 175% in 2008. Graph below shows a graph highlighting Ireland’s exposure to debt.

What is a property bubble?
Property bubbles grow as long as buyers are willing to borrow increasingly large amounts in the expectation that prices will continue to rise. This process inevitably hits a limit where borrowers become reluctant to take on what start to appear as impossibly large levels of debt, and the self-reinforcing spiral of borrowing and prices starts to work in reverse.

Central Bank easing on a global scale.

Below is an image I got from the Business Insider site that shows the extent of monetary easing and tightening by Central Banks around the globe.

A2 Economics – Keynesians vs Monetarists

February 24, 2015 Leave a comment

Just been going through this part of the course with my A2 class and came across a table from some old A Level notes produced by Russell Tillson (ex Epsom College Economics and Politics Department) to help them understand the principal differences.

WE THE ECONOMY – 20 short movies on economics

January 12, 2015 Leave a comment

WE THE ECONOMY website provides a series of short films that explain economic concepts or key features of the modern economy. Each of the 20 movies focuses on some aspect of the U.S. economy or on some economic concept. The films are grouped into five ‘chapters’ covering the basics of the economy:

What is the Economy?
What is Money?
What is the Role of our Government in the Economy?
What is Globalization?
What Causes Inequality?

Every 5-8 minute video is well worth watching and useful for the classroom. Below is the trailer – very professionally done and excellent reinforcement when teaching certain topics.
