06.12.10Localism
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.
Well done: you’ve managed to boil Adam Smith’s mammoth The Wealth of Nations down to a single blog post!
Self-sufficiency is the road to poverty, and the benefits of trade and specialization are limited by the size of the market. Whenever we increase the number of available voluntary trades, we increase prosperity.
One nit: the economic benefits of globalization extend to the most important non-scarce goods in the world. Ideas. An idea is something that can be shared with others without being lost by the sharer, and globalization maximizes the distribution of valuable ideas, including new technologies that can be copied.
Which means that one threat to globalization is the attempt to lock down ideas through intellectual property laws. To the extent “free trade” agreements do this, they are detrimental to actual free trade, which is simply the absence of barriers to trade. So we must always be careful to make sure our support of globalization does not include a support of global interference in the flow of ideas.
Great point. Actually, Tabarrok makes exactly that point in the TED talk I linked to.
[...] 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 [...]
What you say if fine, in a perfect free economy.
But obviously, we don’t have that and you failed to even hint at the fact that the link between far away production centers and their far away markets, that would be transportation, is entirely state subsidized.
It the taxpayers and citizens of all the points from here to there that pay for the shipping of Alaskan salmon and Columbian coffee. Roads, ports, fuel subsidies, acess to resources, hard to even get a hint of the true free market in the field of transportation.
Not to mention state subsidies of products, overfishing, state confiscation of lands, etc, that affect and distort local markets relative to the world market.
So, the choice to buy local is just that, a free choice and is a much freer expression of the market than the transportation of far away products to far away markets.
We have no clue what the “real” cost of purchasing far away products might be but we can guess without state intervention it would be much higher. And, at that point it would truly reflect resource use. It doesn’t come close at present.
We do know that the choice to buy local is just that, a free choice. I would think those who espouse free markets [me included] have no problem with free choice but maybe i am wrong?
