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.
