I am doing one of the “Conversations with Tyler” events on September 24th, and in preparation for that, Tyler Cowen asked his blog readers to submit possible questions. As of this writing, there was a terrific list of challenging questions on the list. I want to offer some thoughts on one of those questions here – both because it has come up before and because it calls for the kind of elaboration that may be difficult at an event of this sort.
Here is the question that Don Boudreaux would like me to address:
“Rodrik was quoted in a 2007 New York Times report as saying that, while he follows the methods of modern economics, he rejects the “faith” [his word] – that says, among other things, that free trade is always good. And, of course, Rodrik is known for his ‘heterodox’ refusal to join in mainstream economists’ embrace of free trade.
So, ask Rodrik if economists who embrace free trade within a country are guilty of faith-based policy recommendations in the same way that he thinks economists who embrace free trade between countries are guilty of faith-based policy recommendations? If he answers no, ask him to summarize the relevant differences that separate intranational from international trade, and press him explain why these differences are real or strong enough to shift the burden of persuasion away from those who oppose a general policy of free trade and onto supporters of free trade.”
Let me preface my answer by stating the obvious: economics does not offer unconditional policy prescriptions. Every graduate student learns that depending on the background specifications, any policy x can be good or bad. A minimum wage can lower or raise employment (depending on whether employers have monopsony power); a natural resource discovery can raise or lower growth (depending on the likelihood of the Dutch disease); fiscal consolidation can expand or contract output (depending on the respective strengths of expectational versus Keynesian effects). And yes, the dictum that free trade benefits a nation depends on a long list of qualifying conditions.
So the proper response to the question “is free trade good?” is, as always, “it depends.” When an economist says “I support free trade” s/he must mean that s/he judges the circumstances under which free trade would not be desirable to be very rare or unlikely to obtain in the context at hand.
Many of the conditions under which free trade between nations is guaranteed to be desirable are unlikely to hold in practice. Market imperfections, returns to scale, macro imbalances, absence of first-best policy instruments are ubiquitous in the real world, particularly in the developing world on which I spend most of my time. This does not guarantee that import restrictions will be necessarily desirable. There are many ways in which governments can screw up, even when they mean well. But it does mean that a knee-jerk free trader response is faith-based rather than science-based.
OK then, what about trade restrictions within nations? If I am a skeptic on free trade between nations, should I not be a skeptic on trade within a nation as well?
No, not really, because I think the set of circumstances under which free trade within a nation may be undesirable is substantially smaller than the set of circumstances under which free trade between nations is undesirable. This is not because the economic logic that drives commerce within a country is different. It is because there are many more degrees of freedom in both the way that a region adjusts to trade and in the possibilities of governmental response.
So consider a case where a region loses out from trade within a nation – say because it de-industrializes rapidly and ends up specializing in technologically non-dynamic primary activities. One thing that can happen within a nation – and not across nations – is that the workers in that region can migrate to other regions and therefore partake in the benefits of trade that accrue elsewhere. That is how, for example, Southern states in the United States adjusted to the industrial dominance of the North.
Another thing that happens is that there is an overarching state that will engage in transfer payments and other policies that aid the lagging region. The region will have political representatives in the national government who will push for the interests of those adversely affected.
A third – particularly important – feature is that a nation shares a common set of regulations (in labor, product, and capital markets). Changes in inter-regional trade patterns are unlikely to be the result of what many people feel are “unfair trade practices” or “tilted playing fields.” When I lose my company or a job, it is because another company worked harder, invested more, or innovated better – not because it denied workers their bargaining rights, despoiled the environment, or received huge subsidies.
This is not to deny that there are differences in institutions and regulations even within nations. Federal systems, such as the one in the U.S., generally admit greater variation. And there is (limited) labor mobility among nations too. But no-one can deny that the borders of the nation state do demarcate jurisdictional boundaries. The possibilities of harmful competition between nations are much larger.
The boundaries of a nation are defined by shared sense of collective purpose, as embodied, in part, in that nation’s common laws and regulations and in its instruments of solidarity. (The problems of the euro zone are in large part the result of the absence of such a common purpose and solidarity.) When citizens of a nation lose that sense of common purpose, we get the demands for break-up and secession.
So the national market and the international market are different. The defining characteristic of a national market is that it is deeply embedded in a set of social and political institutions – a common legal and regulatory framework provided by the nation-state. The international market is at best weakly embedded in transnational arrangements, and the arrangements that do exist such as the WTO and bilateral investment treaties are commercial rather than fully-fledged political/redistributive/regulatory arrangements.
For a libertarian, I suppose this might be a distinction without difference. A libertarian might view much of the regulatory apparatus of the nation-state as superfluous at best and detrimental at worst. For me, the apparatus is what makes capitalism feasible and sustainable at the national level – and problematic at the global level.
Danny's answer is so odd. First, he claims he supports intranational trade since the conditions that would make it undesirable are unlikely in developing countries, where he "spends more of his time". Then he enumerates three conditions which he thinks holds in developing countries. First, labor mobility, which is not smooth in geographically or ethnographically fragmented countries. Second, he assumes that political representatives from affected regions represent the interests of the affected populations. Thirdly, he claims that "when I lose my company or job it is because another company worked harder, invested more or innovated better - not because it denied workers it's bargaining rights, despoiled the environment or received huge subsidies", which clearly sounds like a joke to anyone doing business in developing countries.

"Another thing that happens is that there is an overarching state that will engage in transfer payments and other policies that aid the lagging region. The region will have political representatives in the national government who will push for the interests of those adversely affected."
Why wouldn't these same outcomes apply to foreign competition?
A further question, don't those transfer payments impede incentives to reinvest within the affected region or make it a more desirable place than it really is for the affected workers? Why isn't that malinvestment?

In light of the empirical reality of most developing nation regulatory systems, this strikes me as bizarre,
"The boundaries of a nation are defined by shared sense of collective purpose, as embodied, in part, in that nation’s common laws and regulations and in its instruments of solidarity."
To take one example: In the Central African Republic, it takes an average of 46 days to prepare a container for export and 68 days to complete the procedures required to import a container. Does Prof. Rodrik believe that these procedures were the outcome of a deliberative democracy in which the "collective purpose" of the nation had been discovered? In Singapore the comparable figures are 6 days and 4 days.
I'm sure that Prof. Rodrik can cite legitimate examples of laws and regulations that do, in some sense, represent "a shared sense of collective purpose." That said, the great mass of red tape that is perpetuating global poverty is more likely a combination of protectionist legislation serving cronies and/or poorly thought out rules that serve no one's interest well, except the bureaucrats that thereby collect bribes and "gifts" to get things done.
If it was possible to get Prof. Rodrik to go through every legal and regulatory obstacle to economic freedom in developing nations, I suspect he could only justify a tiny fraction of those laws and regulations either on the grounds of economic efficiency or "collective purpose."
As a consequence of the empirical reality that most laws and regulations in developing nations are unjustifiable (whether with respect to free trade or internal regulation), the morally-motivated economist should emphasize the need to reduce irrational obstacles rather than emphasize those cherry-picked circumstances in which his vision of the world actually has some validity.

The answer provided is less economic than political. Yes, libertarian thought posits all government action beyond security and justice to be superfluous and destructive of liberty and property.
So, the arguments presented is not that there is any economic difference between intra- and international trade, rather political considerations distort markets and can artificially create win-lose propositions where none should exist.
So Prof Rodrik assumes political reality as set and unchangeable, therefore artificial political restrictions on voluntary, peaceful exchange are justifiable in the eyes of those imposing them.
Political fatalism masquerading as economic theory...

This assumption can't be considered universal:
One thing that can happen within a nation – and not across nations – is that the workers in that region can migrate to other regions and therefore partake in the benefits of trade that accrue elsewhere. That is how, for example, Southern states in the United States adjusted to the industrial dominance of the North.
This isn't the case in countries such as Indonesia or China (and many other places) where domestic migration and human movement is controlled. Similarly, this:
Another thing that happens is that there is an overarching state that will engage in transfer payments and other policies that aid the lagging region.
This makes the assumption that the 'overarching state' will inevitably distribute wealth evenly, whereas the disparities between urban and rural revenue distribution can be stark, thinking specifically of Thailand (where it is used to prop up a middle-class voter base for Thai royalists) and, historically, Indonesia, where most of the 14,000 islands that aren't Java (including Sumatra, geographically the largest island) have for the most part been ignored and suffered economically as a result.
I think this all boils down to the assumptions in this statement:
The boundaries of a nation are defined by shared sense of collective purpose, as embodied, in part, in that nation’s common laws and regulations and in its instruments of solidarity.
This is true of a strong state, but the fact is the majority of the world's states are in fact weak. Governments are not accountable, they are absent rule of law, democracy is ineffective. They are not defined by a 'collective purpose'; they are merely defined by an arbitrary political boundary. In other words, Professor Rodrik views a nation state as politically homogeneous; whereas in many cases they are rife with division that can be equal to or worse than international political divisions.

I work in Forex, it is a worldwide business, so that’s the real trading in the whole world. It is really pleasing to work with a business like that, as we can make so much out of it. I trade with OctaFX broker and they got sensational setup with small spread of 0.2 pips, high leverage up to 1.500 while there is also rebate program available, it is superb with allowing me to gain 15 dollars profits per lot size trade and that includes the losing one as well.
