The Economy Is Not Like A Sports Game
Now left-liberal blogger Matthew Yglesias thinks that this is a good analogy for the economy. He argues that Estonia's success in turning its economy around can't be replicated in all the other countries with deep economic problems because there is supposedly only a "finite level of demand" that nations are competing for, and that therefore Estonia's success has been achieved at the expense of others, just like victories in sport championships are achieved at the expense of other teams.
There are 3 reasons why this is wrong. First of all, though it is true that trade- and current account balances are zero sum games on a global level it is certainly not one at the Euro area level as the Euro area is only a limited part of the world.
And furthermore, reductions in external deficits in for example Greece and Portugal or increases in the Estonian surplus can be achieved by reductions in the large surpluses of for example Germany, Holland and Finland.
And secondly, Estonia's 8.4% growth has not been achieved through higher net exports. In fact, Estonia's trade and current account surplus has been somewhat lower this year than the previous year.
And thirdly and perhaps most importantly, it is not true that there is only a finite level of demand and that economic growth is therefore a zero sum game. When new productive activities are performed, it is not just supply but also demand that increases. That is why "aggregate demand" always increases during for example periods of technological progress, and that is also why for example the strong increase in exports in Estonia has been associated with just as strong (in fact, slightly stronger) increase in imports.
That is why following the Estonian role model would be good for Greece, Portugal, Ireland, Italy and Spain-and why that would help and not hurt the rest of Europe as well.
