Protectionism’s many weaknesses
After our lesson on tariffs and protectionism the other day, one of my year 2 IB Econ students emailed me with a few questions she had not had the chance to ask in class. I thought I’d post my responses here, since they were such good questions!
Question: Hi Mr Welker, I asked this on Monday’s blog about self-sufficiency, but no one answered my question and I have been meaning to ask this in class but I always get distracted and I forget. And perhaps you have already answered this, pardon me if you have.
Since Exports and Investment have a great effect on economic growth, why would a government want to protect its nation by imposing barriers to trade? Because by doing so, foreign firms cannot invest in that nation and potentially create job opportunities and also contribute to that nations GDP since, even though it’s a foreign investment, the revenue is collected by that government.
Answer: Protectionism is not typically aimed at reducing the amount of exports from the nation engaging in it, rather reducing the amount of imports or promoting increased exports. You’re exactly right that exports and investment contribute to aggregate demand (and therefore economic growth and employment) in a nation. But imports are a ‘leakage’ from the nation’s economy, and the greater the level of import spending, the lower a nation’s net exports. A nation with a trade deficit actually experiences negative net exports. The purpose of protectionism is to reduce import spending, or increase export revenues, and thereby increase net exports and aggregate demand and employment in the nation.
As for foreign investment, one of the consequences of a large trade deficit is increased foreign ownership of domestic resources or factors of production. Since a country that imports more than it exports spends more on foreign goods than it earns from the sale of its own goods to foreigners, foreign governments and firms end up with large amounts of that country’s money that is NOT being spent on that country’s goods. Much of this ends up back in the deficit country as foreign investment. Sometimes foreigners will buy government bonds (invest in the deficit country’s debt, in other words), but sometimes the money comes back home as foreigners buying up factories and real estate. Foreign investment may indeed help create jobs at home, but so does domestic investment, and when foreigners invest it means the country’s resources are now owned by interests abroad, which many countries view as a threat to their national and economic security. This can also serve as a justification for protectionism: to prevent foreign ownership of domestic assets.
Question: Also if the country is not exporting, it’s not enjoying the benefits of revenue from exported goods that could boost their economic growth. And anyway, isn’t the point of making money to spend it? Otherwise what is the incentive of being employed and earning an income? Unless of course, one can argue that income earned can then be spent on domestically produced goods.
Again, the purpose of protectionism is not to reduce a country’s exports, rather to reduce its imports and to increase its exports. But you have made a very important observation here that points to a major flaw in the argument for protectionism. The purpose of exporting goods it to make money to spend on imported goods, otherwise, WHY TRADE? A country gains from trade not only because it has a wider market for its own goods, but because the people of the nation have a wider market from which to choose the goods they themselves can consume. When a nation erects barriers to trade, it will ultimately have the effect of reducing not only imports, but possibly the nation’s own exports. Since foreigners earn less money from selling goods to the protected nation, they have less money to spend on that nation’s goods!
All protectionism can hope to do is increase the welfare of particular industries while reducing the welfare of the rest of society. It is rarely justifiable on the grounds that it will increase the total welfare of society as a whole, unless of course the protected industry is one vital to national security, such as the defense sectors or the energy sector (even this one is debatable!)
Question: Or do government spending (through subsidies, and creating job opportunities) and increased consumption due to income gains caused by government intervention overcome these factors and compensate for the lost opportunity of exports and investments.
Increasing government spending to off-set the fall in social welfare resulting from protectionism will only lead to greater inefficiency in society. Government may have to spend more on unemployment benefits for workers whose jobs are lost due to protectionism, which may require higher taxes on those workers whose jobs are being protected. As explained above, one industry’s gain leads to a loss of welfare for society as a whole. This is the problem with protectionism. It favors certain industries but imposes higher prices on consumers and higher costs of production on other industries. It should not be the government’s job to “pick winners and losers” in the global economy. By protecting certain industries, however, government attempts to do just that, but society as a whole loses.
I hope you understand what I am asking for here. Whenever you have time, I would love to hear your perspective.

Great questions, Maphrida!
Discussion Questions:
- How might protectionism lead to an increase in aggregate demand and domestic employment?
- Why does a large trade deficit lead to a build-up of foreign ownership of domestic factors of production?
- Discuss the view that protectionism in the form of tariffs on particular goods helps certain industries but harms the rest of society. Can you imagine an example of a protectionist policy that could increase the welfare of society as a whole?
- Explain how a protectionist policy that makes imports more expensive and thus reduces demand for imported goods can ultimately lead to a reduction in demand for the protected country’s exports abroad.
