On Trade Deficits and Tarriffs

PART I: Trade Balances are Worse than Useless

Let's imagine there are only three countries: the US, Canada and Mexico.

Let's further imagine that these three countries produce and consume all the goods and

services that they need locally except for three situations:

1) The US buys lumber from Canada

2) Canada buys steel from Mexico

3) Mexico buys automobiles from the US

Now, the trade balances will go like this:

US: In a trade deficit with Canada that just gets bigger and bigger.

US: In a trade surplus with Mexico that just gets bigger and bigger.

These trade balances don't mean anything. Nothing is out of whack. There is no limit

to how high they can go, and nothing ever needs to be paid back to anybody (it is not

debt).

Therefore I recommend ignoring trade balances entirely. They are a silly useless

metric that causes far too much confusion (including in Trump's mind).

PART II: Trade is win-win

In free markets, people trade with other people only of their own free will. They are

never compelled to make a specific trade. Therefore we can assume that both parties to

a trade doing so willingly actually value the received goods and services moreso than

they value the disposed of goods and services.

Therefore trade is win-win.

Therefore,.the more free trade that occurs, the richer everybody gets.

PART III: Tariffs and their purpose

Tarriffs are local import taxes you charge your own citizens in order to protect

local industries who produce the same products at a higher price. This may be

necessary for a number of different reasons:

1) Local industry is fledgling and not efficient yet, and you are giving them time to improve

2) Currency exchange rates are out of whack from purchasing-power-parity, and so you are

preventing efficient local industry from suffering the devastation of this artificial

imbalance.

Any other reason for imposing tarriffs causes a net loss since as already argued, trade

is win-win.

Trump may impose tarriffs in order to drive a hard bargain, but they are still a net loss

while they last. It is just that in Trump's case, they generally don't last long, they

were more of a threat than a long-term policy.

Since currency exchange rates change rapidly, I am of the opinion that tariffs should

change rapidly too. But they don't. Generally they are written into legislation and hard

to change quickly. IMHO government could do far better in this regard.

This is an oversimplified view. Yes, global free trade is ideal, but it's not as simple as that.

1) generating revenue from paychecks has secondary effects. It makes people unable to save. Generating revenue upstream becomes more of a consumption tax. It matters where the revenue comes from.

2) labor markets are not equal, and free trade is one way to arbitrage them and ultimately bring equilibrium to two different ones, which in the long run is great but in the meantime hurts the people in the one with higher wages, which leads to political will to prevent that from happening.

3) you address using them to protect industries. For a state to maintain powerful warfare fighting capability, it must have security with certain sectors and their supply chain sectors as well. The US subsidizes a coal industry in order to maintain a steel industry because coal is needed to make steel, in order to have vertical integration for it's weapons industry, which it needs in the event of large scale warfare. Food security is also another example of this.

4) the other side of that coin: states will use tariffs to hurt certain key industries of their competitors or rivals, for lots of reasons but the scary one being to make them less able to engage in warfare in the event armed conflict arises. So states need to protect their industries from that as well.

Ultimately we live in a game theoretical system dominated by states. They're going to use the tools at their disposal to engage in soft conflict with one another as they feel they need to. It's like a stable minimum, an arms race, "if we don't use these tools others will and it will hurt us" type scenario. We can wish we lived in a world not dominated by states, work towards that, but this is the reality we live in. In light of all that, are these tariffs still a bad idea? I don't know, but I do know it's not as simple as "free trade makes things cheaper and better for everybody".

Yes of course all of that. I didn't intend to list all reasons to apply tarriffs, just that all these reasons have a negative effect. That negative effect may well be outweighted by the reason. I should have worded it differently.
