Economists are united in support of free trade. Free trade brings great benefits: productivity is increased due to greater specialization from division of labor and all participants enjoy gains from trade. Any restrictions on trade move us away from this optimum. To the extent that beneficial trades are foregone, prosperity is sacrificed and waste is promoted. But the logic of the argument applies not only on the level of nations—it also applies with full force on the level of individuals.

The argument for free trade is a simple, logical proof. Trade is defined as voluntary exchange. From this it follows that all trades are mutually beneficial (ex ante). In other words, each party in a trade expects to benefit. If this were not so, then the exchange would not occur. Nobody will make a trade that they believe will leave them worse off. One would only make a disadvantageous exchange if it were involuntary—but this violates our definition of trade as voluntary exchange. Evidently, if all trades are undertaken because both parties expect to benefit, then any restriction of trade can only serve to eliminate gains from trade. Unrestricted free trade maximizes prosperity. This follows directly from the logic of voluntary exchange.

Now, if economists contend that tariffs are bad because they eliminate mutually beneficial exchanges and breed inefficiency, then they must also oppose sales taxes. For what is a sales tax but a tariff on trade between individuals? Sales taxes increase the cost of trades, eliminating mutually beneficial exchanges. They discourage specialization and trade, and encourage inefficient self-sufficient production.

Furthermore, this principle applies to all taxes that add to the marginal cost of production and trade. An income tax, for example, increases the marginal cost of producing for trade (a portion of each additional dollar earned is lost as taxes). This discourages production and reduces prosperity. It also encourages inefficient self-sufficient production (they don’t tax the work you do for yourself… yet). The only tax that wouldn’t harm incentives to produce and trade would be a tax of fixed amount unrelated to income or wealth (also known as a head tax). Of course, taking peoples’s money via taxation harms them, but a head tax wouldn’t do the added damage of reducing the incentive to produce and trade. Needless to say, a head tax would never be implemented in practice, as it would effectively end the welfare state.

In conclusion, if economists are to be consistent in their principled support of free trade, they must also oppose sales taxes on exactly the same grounds. If a tariff is a bad way to raise government revenues, then so is a sales tax. By the same principle, they must also oppose any tax related to income or wealth. These taxes harm the incentives to produce and trade. If economists are not willing to accept these conclusions, then they must also weaken their support for free trade.

 

The idea that we should “buy local” or that goods should be produced locally is fairly popular, but economically incoherent. There seems to be two main arguments for localism: 1) that long distance transportation is wasteful, and 2) that local spending benefits the local economy and makes people better off. Both arguments are wrong: localism is wasteful and can only impoverish us.

At the most basic level, all goods are produced locally to some people (at least the producers and their neighbors). Why does the location of production matter at all? A head of lettuce moving in a refrigerated truck is the same as a head of lettuce sitting in the refrigerator of the local store. Transportation doesn’t change the nature of the product. Furthermore, “local” is an arbitrary point on a continuum—is local 100 or 1000 miles? Why not 101 or 1001 miles? Taken to its logical conclusion, localism implies that everyone should be a self-sufficient producer and eschew all trade—it doesn’t get any more local than that. To put it bluntly, localism is a bad idea, based on a non-understanding of the economics of trade. Trades are mutually beneficial (else they would not occur) on all levels: from local to global.

Consider an Alaskan and a Colombian trading salmon and coffee. Despite the great distance separating them, this arrangement is the cheapest way of providing the Alaskan with coffee and the Colombian with salmon. If they were to “buy local” they would have to resort to very costly (wasteful) methods of production (such as greenhouses or cold-water tanks) or forgo the product entirely. Needless to say, they are both much worse off without trade.  The general principle I’ve outlined is that cost, not location, is the key factor. Alaskans can produce salmon at a much lower cost than Colombians, who can produce coffee at a much lower cost than Alaskans. If the savings from using efficient production exceed the transportation costs, then they both gain by trading because they can acquire the other product at a lower cost than if it were produced locally. By specializing and trading, they minimize waste and conserve scarce resources. To forgo mutually beneficial trades because of location is to shoot yourself in the foot.

The economics lesson here is about scarcity. Since resources are scarce, we must economize their use in order to maximize prosperity. By using the lowest cost methods of production, we minimize the amount of resources that are used up in producing goods. This leaves more resources for the production of other goods, increasing our well-being. In other words, the least cost method is the least wasteful method. So rather than worry about where the product comes from, just look at its price. If local goods happen to be cheaper, then they were produced less wastefully. Same for faraway goods. (Keep in mind, however, that this only holds in a free market, as government distorts prices which hides true costs). A lower price means that less resources were used in bringing the product to you (including the resources used up in transportation). This is why so many goods are produced non-locally: the savings from producing in a more efficient location exceed the costs of transportation. We all benefit from these savings by enjoying more goods at lower prices.

Globalization is often smeared as evil, but in truth, it is one of the greatest triumphs of human civilization. Localism is the real evil as it engenders waste, which can only bring poverty. Global free trade is the engine of worldwide prosperity and continues to be one of the most important solutions in the eradication of world poverty.

 

The Non-Aggression Principle is the foundation of libertarianism. It forbids aggression, i.e., the initiation of force against others. While there are many different justifications for the NAP, the simplest argument is an appeal to commonsense morality: we should deal with other people through reason and persuasion rather than violence and coercion.

In his article “The Irrelevance of Responsibility,” Roderick Long presents an Aristotelian Golden Mean justification of the NAP. He argues that a flourishing human life requires striking a balance between the subhuman and the superhuman. Since reason is the essential human trait, a truly human life requires relating to others through persuasion. Dealing with others through force is subhuman; but refusing to use force against aggressors is superhuman. Thus the NAP—using force only in defense—represents a Golden Mean between the extremes of subhuman aggression and superhuman pacifism.

I recently created a resources page to list the best material for learning about libertarian anarchism. It will be a pretty exclusive list as I want to keep it short and of highest quality. If you have any suggestions, leave a comment or contact me.
