One of the reasons why it is so hard to forecast economic growth and other macroeconomic indicators is that economies can be affected by economic shocks. Sometimes the effects of shocks are large. The problem with shocks is that, by their very nature, they are unpredictable or hard to predict.
A case in point is the current crisis in Ukraine. First there was the uprising in Kiev, the ousting of President Yanukovich and the formation of a new government. Then there was the seizing of the Crimean parliament by gunmen loyal to Russia. The next day, Saturday March 1, President Putin won parliamentary approval to invade Ukraine and Russian forces took control of the Crimea.
On Monday 3 March, stock markets fell around the world. The biggest falls were in Russia (see chart). In other stock markets, the size of the falls was directly related to the closeness of trade ties with Russia. The next day, with a degree of calm descending on the Crimea and no imminent invasion by Russia of other eastern parts of Ukraine, stock markets rallied.
What will happen to countries’ economies depends on what happens as the events unfold. There could be a continuing uneasy peace, with the West effectively accepting, despite protests, the Russian control of the Crimea. But what if Russia invades eastern Ukraine and tries to annex it to Russia or promote its being run as a separate country? What if the West reacted strongly by sending in troops? What if the reaction were simply sanctions? That, of course would depend on the nature of those sanctions.
Some of the possibilities could have serious effects on the world economy and especially the Russian economy and the economies of those with strong economic ties to Russia, such as those European countries relying heavily on gas and oil imports from Russia through the pipeline network.
Economists are often criticised for poor forecasts. But when economic shocks can have large effects and when they are hard to predict by anyone, not just economists, then it is hardly surprising that economic forecasts are sometimes highly inaccurate.

World leaders are meeting at the World Economic Forum in Davos, in the Swiss Alps. This annual conference is an opportunity for politicans, economists and businesspeople from around the world to discuss the state of the world economy and to consider policy options.
To coincide with the conference, the BBC’s Newsnight has produced the following slide show, which presents some economic facts about the world economy. The slide show provides no commentary and there is no commentary either in this blog – just some questions for you to ponder.
Using the economics you’ve learned so far, try answering these questions, which focus on the reasons for the patterns in the figures, the likely future patterns and the policy implications.

Questions
- Go through each of the slides in the Newsnight presentation and select the ones of most interest to you. Then, as an economist, provide an explanation for them.
- Identify some patterns over time in the statistics. Then project forward 20 years and discuss whether the patterns are likely to have changed and, if so, why.
- What policies could governments adopt to reverse any undesirable trends you have identified? How likely are these policies to be implemented and how successful are they likely to be?
The 159 member countries of the World Trade Organisation have reached an agreement on liberalising trade. The deal, which was reached on 6 December 2013 at a meeting in Bali, is the first substantial agreement since the WTO was formed in 1995 (see Timeline: World Trade Organization for other agreements).
It involves simplifying customs procedures and making them more transparent, limited reductions in tariffs and quotas and allowing greater access to WTO members’ markets for exporters. It also permits developing countries to continue subsidising their agriculture in order to promote food security, provided the practice does not distort international trade. According to the WTO:
The trade facilitation decision is a multilateral deal to simplify customs procedures by reducing costs and improving their speed and efficiency. It will be a legally binding agreement and is one of the biggest reforms of the WTO since its establishment in 1995. …The objectives are: to speed up customs procedures; make trade easier, faster and cheaper; provide clarity, efficiency and transparency; reduce bureaucracy and corruption, and use technological advances. It also has provisions on goods in transit, an issue particularly of interest to landlocked countries seeking to trade through ports in neighbouring countries.
In a report published by the Peterson Institute in Washington, it is estimated that the extra trade will add some $960bn to world GDP and create some 20.6m extra jobs. 
But how fully does it meet the objectives of the Doha Development Agenda, the yet-to-be-concluded trade round started in Qatar in November 2001?
According to the EU’s trade commissioner Karel De Gucht, about one quarter of the goals set for the Doha Round have been achieved in this agreement. This, of course, still leaves a long way to go if all the Doha objectives are to be met. World trade, although now likely to be somewhat freer, is still not free; developing countries will still find restricted access for their agricultural products, and manufactures too, to many markets in the rich world; rich countries will still find restricted access for their manufactured products and services to many markets in the developing world.

Questions
- According to the law of comparative advantage, there is a net gain from international trade. Explain why.
- What are the likely gains from freer trade?
- Is freer trade necessarily better than less free trade?
- Who is likely to gain most from the WTO deal reached in Bali?
- What were the goals of the Doha Development Agenda?
- In what ways does the Bali agreement fall short of the goals set at Doha in 2001?
- Why is it so difficult to reach a comprehensive international deal on trade liberalisation that also protects the interests of poor countries?
- Do you agree with the World Development Movement (WDM) that the Bali Package is “an agreement for transnational corporations, not the world’s poor”?
- Would it now benefit the world for individual countries to pursue bilateral trade deals?
The world’s population is set to go on rising – at least to 2050. And as population rises, so will the demand for food. But here we come up against a potentially catastrophic illustration of the law of diminishing returns. Population is set to grow, but the world supply of land is pretty well fixed. And with global warming, some land may become unusable.
According to Sir John Beddington, an expert in population biology and lead author of a government-commissioned report, The Future of Food and Farming, there could be serious consequences of this population rise, including rapid rises in the demand for food, rising food prices, rising land prices, the degradation of land, growing food poverty in many developing countries, growing political unrest and serious environmental damage. As the report’s Executive Summary states:
The global food system will experience an unprecedented confluence of pressures over the next 40 years. On the demand side, global population size will increase from nearly seven billion today to eight billion by 2030, and probably to over nine billion by 2050; many people are likely to be wealthier, creating demand for a more varied, high-quality diet requiring additional resources to produce. On the production side, competition for land, water and energy will intensify, while the effects of climate change will become increasingly apparent. The need to reduce greenhouse gas emissions and adapt to a changing climate will become imperative. Over this period globalisation will continue, exposing the food system to novel economic and political pressures.
Any one of these pressures (‘drivers of change’) would present substantial challenges to food security; together they constitute a major threat that requires a strategic reappraisal of how the world is fed.
The report specifically looks at five key challenges for the future:
A. Balancing future demand and supply sustainably – to ensure that food supplies are affordable.
B. Ensuring that there is adequate stability in food prices – and protecting the most vulnerable from the volatility that does occur.
C. Achieving global access to food and ending hunger – this recognises that producing enough food in the world so that everyone can potentially be fed is not the same thing as ensuring food security for all.
D. Managing the contribution of the food system to the mitigation of climate change.
E. Maintaining biodiversity and ecosystem services while feeding the world.

The link below is to a podcast by Martin Wolf of the Financial Times. It considers a new book, Fault Lines by Raghu Rajan of the University of Chicago Booth School of Business. Rajan argues that the global economy is severely unbalanced:
There is a fair amount of consensus that the world economy is in need of rebalancing. Countries like Iceland, Greece, Spain, and the United States overspent prior to the crisis, financing the spending with government or private borrowing, while countries like Germany, Japan, and China supplied those countries goods even while financing their spending habits. Simply put, the consensus now requires U.S. households to save more and Chinese households to spend more in order to achieve the necessary rebalancing.
Martin Wolf identifies these imbalances and discusses various possible solutions. The problem is that what may seem sensible economically is not always feasible politically.

Questions
- What are the fault lines that Martin Wolf identifies?
- Have they become more acute since the credit crunch and subsequent recession?
- What risks do these fault lines pose to the future health of the global economy?
- How do political relationships make integrating the world economy more difficult? What insights does game theory provide for understanding the tensions in these relationships?
- Is a policy of export-led growth a wise one for the UK to pursue?
- Explain why global demand may be structurally deficient.
