Is the common view in the field of economics that ‘Free Trade’ is the best way forward for the world economy true? Yes. However we are living in a time whereby the field of economics is in despair and disillusion. No longer can we assume that all the theories put forward by economists in the past, and that have worked in the past, are the best options to take in this moment in time. What I am trying to say is that in this day and age there is certainly room for debate in the ‘Free Trade vs. Protectionism’ argument.
The economic case against protectionism is that it distorts incentives: each country produces goods in which it has a comparative disadvantage, and consumes too little of imported goods. And under normal conditions that’s the end of the story. But these are not normal conditions. We’re in the midst of a prolonged global slump, with governments everywhere having trouble coming up with an effective response. The crux of the problem facing us is that there are major policy externalities that are constantly arising. For example, if country X’s fiscal stimulus (measures taken by the government, normally involving increased public spending and lower taxation, aimed at giving a positive jolt to economic activity) helps country Y’s economy by increasing their exports, there is a problem since country Y will not experience X’s addition to government debt. Therefore the benefit that occurs as a result of fiscal stimulus for one country is less than it is for the world as a whole. Subsequently, this means if macroeconomic policy is not coordinated internationally- and it most certainly is not- there will tend to be too little fiscal stimulus, everywhere.
Now ask, how would this change if each country adopted protectionist measures that “contained” the effects of fiscal expansion within its domestic economy? Then every government would adopt a more expansionary policy — and the world would get closer to full employment than it would have otherwise. Yes, trade would be more distorted, which is a cost; but the distortion caused by a severely underemployed world economy would be reduced. You must understand that this is not a cry for protectionist policies at all times, rather it is a second-best argument; a way in which the world must adjust to the ever-changing economic climate it is currently experiencing.
Everything I’ve just said only applies when the world is stuck in a liquidity trap (money is not readily accessible), which is what is going on in the world today. But this shall not be the normal situation. If we do go all protectionist in the long term it will destroy all the advancements made in trade negotiations over the past century, and it would take a long time to put the pieces together again. Nonetheless, there is a short run case for protectionism which will only increase in force and plausibility if an effective economic recovery program is not found.
