Economics, but not as we know it. As the introduction to this programme on BBC radio 4 suggests, there has been criticism and concern about the way in which we think about economics. About, how it’s taught; the lessons we learn and whether we need to have a re-think. Tomas Sedlacek is a Czech economist and has a different way of thinking about this subject.
Humanomics is certainly a new way of thinking about economics and considering how it links and can be applied to a wide range of areas: the Bible; movies such as Fight Club and the Matrix. This 30 minute discussion between Evan Davies and Tomas Sedlacek provides some interesting insights and thoughts on some of the current challenges facing this subject and some novel insights into how we could change our thinking.
Tomas Sedlacek: The Economics of Good and Evil BBC Radio 4 (25/01/16)
Questions
- How do we define and measure value? Is this always possible? Can you think of some things where we cannot assign prices or numbers to values?
- How could economics be relevant Adam and Eve?
- Think about the marriage market. How would you apply the model of demand and supply to this most unusual of markets?
- What insights does Tomas Sedlacek provide about the ancient business cycle and this might affect our thinking about debt and assets?
- Do you think that refugees are of benefit to a country? If you don’t think they are of benefit, does this mean that countries should not accept them?
- If we did find out that corruption or crime and terrorism were of benefit to the GDP of a country, would you encourage it? Or would you place the morality issue above the actual figure of contribution?
The latest GDP numbers from the Office for National Statistics contained in Quarterly National Accounts, Q2 2014 show the economy’s output expanded by 0.9 per cent in the second quarter. This follows on the back of a 0.7 per cent increase in output in Q1 2014. The economy’s output is now thought to be 0.7 per cent above its Q1 2008 peak. Yet, the data show very different profiles for the four principal industrial sectors. The service sector appears to be ploughing ahead while the rest (production, construction and agriculture) lag behind.
Chart 1 shows quarterly economic growth since 1980s (click here for a PowerPoint of the chart). It illustrates nicely the inherent volatility of economies – one of the threshold concepts in economics. The average quarterly rate of growth since 1980 has been 0.5 per cent. On the face of it, a quarterly growth number of 0.9 per cent would appear very robust. Of course, this has to been set in the context of the 2008/9 recession. UK output peaked in Q1 2008 (£414.424 billion at 2011 prices). The revised data now show that there followed 5 quarters of declining output (previously, data suggested the duration of the recession was 6 quarters). During this period output shrank 6 per cent (GDP at 2011 prices had fallen by Q2 2009 to £389.388 billion ).
Chart 1 highlights two earlier downturns. First, there is the recession of the early 1980s. We can see the 5-quarter recession that commenced in Q1 1980. By the end of this recession output had shrunk by 4.5 per cent. Second, there is the recession of the early 1990s which commenced in Q3 1990. Again, this recession lasted five quarters. By the time the economy had come out of recession it had shrunk 2.2 per cent.
Consider now Chart 2 (click here for a PowerPoint of the chart). It allows us to analyse more recent events by tracking how industrial output has evolved since 2006. It suggests an unbalanced recovery. From it, we observe that in Q2 2014 service-sector output was 6.5 per cent higher than in Q1 2008. However, a very different picture emerges for the other principal industrial types. Output across the production industries remains 9.7 per cent lower, 9.2 per cent lower in agriculture and 8.9 per cent lower in the construction sector.
In short, the British economy continues to struggle to rebalance its industrial base. The business cycle remains heavily dependent on the service sector.

Commodity prices have been falling for the past three years and have reached a four-year low. Since early 2011, the IMF overall commodity price index (based on 2005 prices) has fallen by 16.5%: from 210.1 in April 2011 to 175.4 in August 2014. The last time it was this low was December 2010.
Some commodity prices have fallen by greater percentages, and in other cases the fall has been only slight. But in the past few months the falls have been more pronounced across most commodities. The chart below illustrates these falls in the case of three commodity groups: (a) food and beverages, (b) agricultural raw materials and (c) metals, ores and minerals. (Click here for a PowerPoint of the chart.)
Commodity prices are determined by demand and supply, and factors on both the demand and supply sides have contributed to the falls.
With growth slowing in China and with zero growth in the eurozone, demand for commodities has shown little growth and in some cases has fallen as stockpiles have been reduced.
On the supply side, investment in mining has boosted the supply of minerals and good harvests in various parts of the world have boosted the supply of many agricultural commodities.
But in historical terms, prices are still relatively high. There was a huge surge in commodity prices in the period up to the financial crisis of 2008 and then another surge as the world economy began to recover from 2009–11. Nevertheless, taking a longer-term perspective still, commodity prices have risen in real terms since the 1960s, but with considerable fluctuations around this trend, reflecting demand and supply at the time.

Questions
- Identify specific demand-and supply-side factors that have affected prices of (a) grains; (b) meat; (c) metal prices; (d) oil.
- Why is the demand for commodities likely to be relatively inelastic with respect to price, at least in the short term? What are the implications of this for price responses to changes in supply?
- Why may there currently be a ‘buying opportunity’ for potential commodity purchasers?
- What is meant by the ‘futures market’ and future prices? Why may the 6-month future price quoted today not necessarily be the same as the spot price (i.e. the actual price for immediate trading) in 6 months’ time?
- How does speculation affect commodity prices?
- How does a strong US dollar affect commodity prices (which are expressed in dollars)?
- How may changes in stockpiles give an indication of likely changes in commodity prices over the coming months?
- Distinguish between real and nominal commodity prices. Which have risen more and why?
- How do real commodity prices today compare with those in previous decades?
The latest preliminary GDP estimates for 2014 Q1 suggest that the economy’s output (real GDP) expanded by 0.8 per cent following on the back of a 0.7 per cent increase in 2013 Q4. Growth was observed in three of the four main industrial sectors: 0.9% in services, 0.8% in production and 0.3% in construction. In contrast, output decreased by 0.7% in agriculture. The total output of the economy is now just 0.6 per cent below its 2008 Q1 peak with the output of the service sector now 2.0 per cent higher.
Data on growth need to be set in the context of the inherent volatility of economies and in this case in the context of 2008/9 recession. Then, output fall by some 7.2 per cent. UK output peaked in 2008 Q1 (£392.786 billion at 2010 prices). There then followed 6 quarters during which output declined.
Output declined again in 2010 Q4 (-0.2% growth), in 2011 Q4 (-0.1% growth), in 2012 Q2 (-0.4%) and in 2012 Q4 (-0.2%). A double-dip recession was only narrowly avoided with growth recorded at zero on 2012 Q1. The latest ONS numbers show the economy grew by 0.8 per cent in 2013 Q2 (to £381.318 billion at 2010 prices), by 0.8 per cent in 2013 Q3 (to £384.533 billion at 2010 prices), by 0.7 per cent in 2013 Q4 (to £387.138 billion at 2010 prices) and by 0.8 per cent in 2014 Q1 (to £390.235 billion at 2010 prices). Compared with 2013 Q1, the output of the UK economy in 2014 Q1 is 3.1 per cent higher.
Chart 1 helps to put the recent growth numbers into an historical context. It shows the quarterly change in real GDP since the 1980s. We can see the 5-quarter recession that commenced in 1980 Q1 when output shrunk by 4.6 per cent, the 5-quarter recession that commenced in 1990 Q3 when output shrank by 2.4 per cent and the 6-quarter recession that commenced in 2008 Q2 when output shrank by 7.2 per cent. (Click here to download the chart to PowerPoint.)
Chart 2 scratches a little below the surface by looking at output by the 4 principal industrial types. The interesting finding is that the output of the service sector has now risen above its 2008 Q1 peak. In 2014 Q1, service sector output was 2.0 per cent higher than 2008 Q1. The fact that total output remains 0.6 per cent lower can be explained by the lop-sided industrial recovery. Output in agriculture, forestry and fisheries remains 7.1 per cent lower, production (including manufacturing) 11.5 per cent lower and construction 12.2 per cent lower.

The latest preliminary GDP estimates for 2013 Q3 suggest that the economy’s output (real GDP) expanded by 0.8 per cent following on the back of a 0.7 per cent increase in Q2. Growth was observed across the main industrial sectors with the important service sector growing by 0.7 per cent. While the output of the service sector is now 0.5 per cent higher than its 2008 Q1 peak, the total output of the economy remains 2.6 per cent below its 2008 Q1 peak.
The volatility of growth underpins the idea of business cycles and on occasions results in recessions. Today’s release needs to be set in the context of this volatility and in the context of 2008/9 recession which saw output fall by 7.2 per cent. UK output peaked in 2008 Q1 (£392.786 billion at 2010 prices). There then followed 6 quarters during which output declined.
Output declined again in 2010 Q4 (–0.2% growth) and again in 2011 Q4 (–0.1% growth). The estimates of real GDP for 2011 Q4 and 2012 Q1 are identical at £376.462 billion (at 2010 prices). Previous revisions have seen the 2012 Q1 growth number revised up so that a further recession resulting in a double-dip recession no longer appears in the figures.
While output is now portrayed as (very) flat in 2012 Q1, it did fall again in 2012 Q2 (–0.5 per cent growth) and in 2012 Q4 (–0.3 per cent growth). Moving forward in time, the latest ONS numbers show an economy that grew by 0.4 per cent in 2013 Q1 (to £377.301 billion at 2010 prices), by 0.7 per cent in 2013 Q2 (to £379.780 billion at 2010 prices) and by 0.8 per cent in 2013 Q3 billion (to £382.818 billion at 2010 prices). Compared with 2012 Q3, the output of the UK economy in 2013 Q2 is 1.5 per cent higher.
Chart 1 helps to put the recent growth numbers into an historical context. It shows the quarterly change in real GDP since the 1980s. From it, we can see the 5-quarter recession that commenced in 1980 Q1 when output shrunk by 4.6 per cent, the 5-quarter recession that commenced in 1990 Q3 when output shrank by 2.4 per cent and the 6-quarter recession that commenced in 2008 Q2 when output shrank by 7.2 per cent. (Click here to download a PowerPoint of the chart.)
Chart 2 scratches a little below the surface by looking at output by the four principal industrial types. The interesting finding is that the output of the service sector has now risen above its 2008 Q1 peak. In 2013 Q3 output is 0.5 per cent larger. By contrast, the other three sectors remain smaller than in 2008 Q1. Agriculture, forestry and fisheries is 5.9 per cent smaller, construction 14.3 per cent smaller and production (including manufacturing) is 14.6 per cent smaller. (Click here to download a PowerPoint of the chart.)
With today’s release, quarterly growth now averages –0.11 per cent since 2008 Q2. If we take the series back to the mid 1950s when it began, the average quarterly rate of growth is 0.64 per cent which is equivalent to an annual rate of increase of 2.57 per cent. While today’s news is encouraging it remains important to keep it in perspective and to ensure that growth is sustainable and built on firm foundations.
