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.

Buckwheat Prices – the true indicator of the Russian economy

December 8, 2014 Leave a comment

BuckwheatA hat tip once again to colleague David Parr for this piece on buckwheat prices. As Russia comes to term with falling oil prices, a depreciating rouble, high inflation and sanctions over the Ukrainian crisis there is one other indicator that is worth a mention – buckwheat prices.

Buckwheat is seen as part of the Russian staple diet and can be eaten with any meal in Russia – porridge, served with liver, stuffed inside a roast piglet. It was when rumours started that buckwheat supplies were running low that shoppers rushed out to supermarkets to fill their trolleys. A drought in Russia reduced the buckwheat harvest from 700,000 tonnes to under 600,000 tonnes but this could hardly cause the rapid increase in prices. However media reports were enough to act as a catalyst for panic buying amongst consumers -it took only four days for the town of Penza to be stripped of buckwheat stocks which normally last for two months. In Moscow buckwheat rose from around 30 rubbles to 50 rubbles. Furthermore with the introduction of Western sanctions people are starting to stock pile buckwheat as they are unsure of what will eventuate. It is estimated that over a third of the population have stocked up on buckwheat over the last month.

It seems that buckwheat is a sacred food for Russians and it tends to be in very short supply when there is any sign of crisis in the economy. But it is not just buckwheat which has increased in price. There has been a 30-40% increase in basic foods such as eggs, fish chicken, and sausages as Russia enforces retaliatory embargo banning Western food imports.

Quirky Economic Indicator – length of a ladder

September 22, 2014 1 comment

Listening to “From Our Own Correspondent” on the BBC World Service I came across an interesting piece by Kate Adie on Global Trade. With the downturn in global trade the international transport industry has been very much affected. Those that have been associated with the distribution of goods get an early indication of the slowdown in global growth. The obvious indicators are: idle cranes, queues of merchant ships dwindle etc. But what about the speed of cargo ships and the length of ladders to climb aboard?

When the world economy was “steaming” ahead the captain of a merchant ship said that they cruised at 20 knots but when the economic crisis of 2008 arrived we slowed to 16 knots. A harbour pilot summed up the state of world trade by the length of the ladders that he climbs on the sides of ships.

A long climb up the ladder signifies that the ship is high in the water and exports are correspondingly low.

A short climb up the ladder signifies that the ship is low in the water and exports are correspondingly high.

The seafarers say that they take air to China before they load up with goods for the US.

Stock Market Returns and the Weather

August 4, 2014 Leave a comment

Snow covers a street sign at the corner of Wall St. and Broad St. in New York's financial districtAn interesting paper by Ming Dong, Andréanne Tremblay of York University, Toronto investigated the effects of five weather conditions (sunshine, wind, rain, snow depth, and temperature) on daily index returns of 49 countries from 1973 to 2012.

The effects of the weather on mood depend critically on geographical regions, and more precisely, on regions defined by their annual average temperature. The emotional effects of other weather variables may be also specific to the temperature region – in hot countries rain might seen as a positive whilst in cold climates rain could be seen to exacerbate the cold climate. However they make two assumptions:

1. Comfortable weather should lead to an upbeat investor mood and therefore high stock returns.
2. The weather effects on returns should be stronger when people spend more time outdoors or when outdoor time is more valuable.

Here are some of their findings:

Cold Countries

In the cold region, the positive sunshine effect on returns concentrates in the summer, when investors spend more time outdoors, and in late winter and early spring, when the marginal utility of outdoor experience may be particularly high after a long winter. However very cold weather is also associated with higher returns which suggest that cold stimulates risk-taking, referring to psychological studies in which participants reported increased aggression as temperatures dropped below -8 degrees C.

Hot Countries

Sunshine has a positive effect on returns during the warmer portion of the year, from May through September—but not June or July, presumably because the scorching sun compromises the outdoor time during peak heat. The sunshine effect is also strong from December to February, consistent with the idea that sunshine brings pleasant warmth during the winter when people still spend considerable time outdoors.

Mild Countries

Stock returns and temperature are strongly negatively correlated in the winter (from December to February). This finding is incompatible with the comfortable weather hypothesis, because it is unlikely that during winter times in the cold region, lower temperature leads to happy mood.


1. The effects of the weather on stock returns depend critically on the temperature environment, which is characterised by geographical region and month of the year.

2. All five weather conditions significantly influence returns, especially during seasons when people expect to spend, or highly value, time in the outdoors.

Developing Economies Case Studies

Devel Countries flagsHere is something that I picked up from David Carpenter’s blog post on the Tutor2u site. It is an ebook put together by his A level economics class and is a useful guideline to the characteristics of Developing Countries. It goes through 5 categories for each country

1. History
2. Geography
3. Politics
4. Economy and Trade
5. Poverty & Income Inequality

This would be a worthwhile exercise for those doing Cambridge A2 economics Unit 6. Click below to download.

ANZ Truckometer

December 11, 2013 Leave a comment

Heard about this indicator on National Radio Morning Report programme this morning and is another variable that can be useful to gauge the state of the economy. The ANZ Truckometer is a set of two economic indicators derived using traffic volume data from around the country. Traffic flows are a real-time and real-world proxy for economic activity –particularly for the New Zealand economy, where a large proportion of freight is moved by road. It represents an extremely timely barometer of economic momentum. The ANZ Heavy Traffic Index shows a strong contemporaneous relationship to GDP, while the ANZ Light Traffic Index has a six month lead on activity as measured by GDP. Notice the change around 2007/08 with the GFC.

Libya – Fastest growing economy in 2012 but what does it mean?

November 23, 2012 Leave a comment

The Daily Chart in The Economist recently looked at the fastest growing and contracting economies since 1980. The main points:

Fastest Growing: In 2012 Libya with 122% growth came out on top – due to the recovery of oil production. However you must remember that this is a % change from the previous year when the economy contracted by about 60% with the civil unrest and the departure of foreign oil companies. Statistically this creates a smaller base when you calculate % change.

If a country’s GDP shrinks by 60%, it must grow by 150% just to restore its former size. Thus even if Libya fulfills the IMF’s forecast for this year, its GDP will still be smaller than it was in 2010

The Economist also looked at other countries that had fast growth rates but this was predominately due to a disaster of some sort in the preceding year or the discovery of a natural resource.

Equitorial Guinea – In the 1990‘s very poor and depended on cocoa and timber for income. 1996 they discovered oil and attracted FDI. After producing 80,000 barrels per day increasing GDP by 150%.

Kuwait – contracted 41% during the first Gulf War on 1991 but grew 50% the next year as growth started to return.
