Daly No policy prescription commands greater consensus among econ- omists than that of free trade based on intemational specialization ac- cording to comparative advantage. Free trade has long been presumed good un- less proved otherwise. That presump- tion is the cornerstone of the existing General Agreement on Tariffs and Trade (GATT) and the proposed North Amer- ican Free Trade Agreement (NAFTA). The proposals in the Uruguay Round of negotiations strengthen GATT's basic commitment to free trade and econom- ic globalization. Yet that presumption should be re- versed. The default position should fa- vor domestic production for domestic markets. When convenient, balanced in- ternational trade should be used, but it should not be allowed to govern a country's affairs at the risk of environ- mental and social disaster. The domes- tic economy should be the dog and in- temational trade its tail. GATT seeks to tie all the dogs' tails together so tightly that the international knot would wag the separate national dogs. The wiser course was well expressed in the overlooked words of John May- nard Keynes: "I sympathize, therefore, with those who would minimize, rather than those who would maximize, eco- nomic entanglement between nations. Ideas, knowledge, art, hospitality, trav- el-these are the things which should of their nature be intemational. But let goods be homespun whenever it is rea- sonably and conveniently possible; and, above all, let finance be primarily na- tional." Contrary to Keynes, the defend- ers of the proposed Uruguay Round of changes to GATT not only want to downplay "homespun goods," they also want finance and all other services to become primarily intemational. Economists and environmentalists are sometimes represented as being, respectively, for and against free trade, but that polarization does the argu- ment a disservice. Rather the real de- bate is over what kinds of regulations are to be instituted and what goals are legitimate. The free traders seek to max- imize profits and production without regard for considerations that repre- sent hidden social and environmental costs. They argue that when growth has made people wealthy enough, they will have the funds to clean up the damage done by growth. Conversely, environ- mentalists and some economists, my- self among them, suspect that growth is increasing environmental costs faster than benefits from production-there- by making us poorer, not richer. A more accurate name than the per- suasive label "free trade"-because who can be opposed to freedom?-is "dereg- ulated intemational commerce." Dereg- ulation is not always a good policy: re- call the recent experience of the U.S. with the deregulation of the savings and loan institutions. As one who formerly taught the doctrine of free trade to col- lege students, I have some sympathy for the free traders' view. Nevertheless, my major concem about my profession to- day is that our disciplinary preference for logically beautiful results over fac- tually grounded policies has reached such fanatical proportions that we econ- omists have become dangerous to the earth and its inhabitants. The free trade position is grounded in the logic of comparative advantage, first explicitly formulated by the early l9th- century Bntish economist David Ricar- do. He observed that countries with dif- ferent technologies, customs and re- sources will incur different costs when they make the same products. One country may find it comparatively less costly to mine coal than to grow wheat, but in another country the opposite may be true. If nations specialize in the products for which they have a com- parative advantage and trade freely to obtain others, everyone benefits. The problem is not the logic of this argument. It is the relevance of Ricar- do's critical but often forgotten assump- tion that factors of production (espe- cially capital) are intemationally immo- bile. In today's world, where billions of dollars can be transferred between nations at the speed of light, that es- sential condition is not met. Moreover, free traders encourage such foreign in- vestment as a development strategy. In short, the free traders are using an ar- gument that hinges on the impermabil- ity of national boundaries to capital to support a policy aimed at making those same boundaries increasingly pemme- able to both capital and goods! That fact alone invalidates the as- sumption that international trade will inevitably benefit all its partners. Fur- thermore, for trade to be mutually ben- eficial, the gains must not be offset by higher liabilities. After specialization, nations are no longer free not to trade, and that loss of independence can be a liability. Also, the cost of transporting goods internationally must not cancel out the profits. Transport costs are en- ergy intensive. Today, however, the cost of energy is frequently subsidized by governments through investment tax credits, federally subsidized research and military expenditures that ensure access to petroleum. The environmen- tal costs of fossil-fuel burning also do not factor into the price of gasoline. To the extent that energy is subsidized, then, so too is trade. The full cost of en- ergy, stripped of these obscuring subsi- dies, would therefore reduce the initial gains from long-distance trade, wheth- er international or interregional. Free trade can also introduce new inefficiencies. Contrary to the im- plications of comparative advan- tage, more than half of all internation- al trade involves the simultaneous im- port and export of essentially the same goods. For example, Americans import Danish sugar cookies, and Danes import American sugar cookies. Exchanging recipes would surely be more efficient. It would also be more in accord with Keynes's dictum that knowledge should be international and goods homespun (or in this case, homebaked). Another important but seldom men- tioned corollary of specialization is a reduction in the range of occupation- al choices. Uruguay has a clear compar- ative advantage in raising cattle and sheep. If it adhered strictly to the rule of specialization and trade, it would afford its citizens only the choice of being ei- ther cowboys or shepherds. Yet Uru- guayans feel a need for their own legal, financial, medical, insurance and educa- tional services, in addition to basic agri- culture and industry. That diversity en- tails some loss of efficiency, but it is nec- essary for community and nationhood. Uruguay is enriched by having a sym- phony orchestra of its own, even though it would be cost-effective to import bet- ter syrnphony concerts in exchange for wool, mutton, beef and leather. Individ- uals, too, must count the broader range of choices as a welfare gain: even those who are cowboys and shepherds are surely enriched by contact with coun- trymen who are not vaqueros or pas- tores My point is that the community di- mension of welfare is completely over- looked in the simplistic argument that if specialization and trade increase the per capita availability of commodities, they must be good. Let us assume that even after those liabilities are subtracted from the gross returns on trade, positive net gains still exist. They must still offset deeper, more fundamental problems. The argu- ments for free trade run afoul of the three basic goals of all economic poli- cies: the efficient allocation of resourc- es, the fair distnbution of resources and the maintenance of a sustainable scale of resource use. The first two are tradi- tional goals of neoclassical economics. The third has only recently been recog- nized and is associated with the view- point of ecological, or steady-state, eco- nomics. It means that the input of raw materials and energy to an economy and the output of waste materials and heat must be within the regenerative and ab- sorptive capacities of the ecosystem. In neoclassical economics the efficient allocation of resources depends on the counting and intemalization of all costs. Costs are internalized if they are directly paid by those entities responsible for them-as when, for example, a manu- facturer pays for the disposal of its fac- tory wastes and raises its prices to cov- er that expense. Costs are externalized if they are paid by someone else-as when the public suffers extra disease, stench and nuisance from uncollected wastes. Counting all costs is the very basis of efficiency. Economists rightly urge nations to follow a domestic program of internal- izing costs into prices. They also wrong- ly urge nations to trade freely with oth- er countries that do not intemalize their costs (and consequently have lower pric- es). If a nation tries to follow both those policies, the conflict is clear: free com- petition between different cost-internal- izing regimes is utterly unfair. Intemational trade increases compe- tition, and competition reduces costs. But competition can reduce costs in two ways: by increasing efficiency or by low- ering standards. A firm can save money by lowering its standards for pollution control, worker safety, wages, health care and so on-all choices that exter- nalize some of its costs. Profit-maximiz- ing firms in competition always have an incentive to exterr*lize their costs to the degree that they can get away with it. For precisely that reason, nations maintain large legal, administrative and auditing structures that bar reductions in the social and environmental stan- dards of domestic industries. There are no analogous international bodies of law and administration; there are only national laws, which differ widely. Con- sequently, free international trade en- courages industries to shift their pro- duction activities to the countries that have the lowest standards of cost inter- nalization-hardly a move toward glob- al efficiency. A ttaining cheapness by ignoring real costs is a sin against effi- ciency. Even GATT recognizes that requiring citizens of one country to compete against foreign prison la- bor would be carrying standards-low- ering competition too far. GATT there- fore allows the imposition of restric- tions on such trade. Yet it makes no similar exception for child labor, for un- insured risky labor or for subsistence- wage labor. The most practical solution is to per mit nations that internalize costs to levy compensating tariffs on trade with nations that do not. "Protectionism"- shielding an inefficient industry against more efficient foreign competitors-is a dirty word among economists. That is very different, however, from protect- ing an efficient national policy of full- cost pricing from standards-lowering international competition. Such tariffs are also not without pre- cedent. Free traders generally praise the fairness of "antidumping" tariffs that discourage countries from trading in goods at prices below their production costs. The only real difference is the decision to include the costs of environ- mental damage and community welfare in that reckoning. This tariff policy does not imply the imposition of one country's environ- mental preferences or moral judgments on another country. Each country should set the rules of cost internalization in its own market. Whoever sells in a na- tion's market should play by that na- tion's rules or pay a tariff sufficient to remove the competitive advantage of lower standards. For instance, under the Marine Mammal Protection Act, all tuna sold in the U.S. (whether by U.S. or Mex- ican fishermen) must count the cost of limiting the kill of dolphin associat- ed with catching tuna. Tuna sold in the Mexican market (whether by U.S. or Mex- ican fishermcn) need not include that cost. No standards are being imposed through "environmental imperialism"; paying the costs of a nation's environ- mental standards is merely the price of admission to its market. Indeed, free trade could be accused of reverse environmental imperialism. When firms produce under the most perrnissive standards and sell their prod- ucts elsewhere without penalty, they press on countries with higher stan- dards to lower them. In effect, unre- stricted trade imposes lower standards. Unrestricted intemational trade also raises problems of resource distribu- tion. In the world of comparative ad- vantage described by Ricardo, a nation's capital stays at home, and only goods are traded. If firms are free to relocate their capital intemationally to wherev- er their production costs would be low- est, then the favored countries have not merely a comparative advantage but an absolute advantage. Capital will drain out of one country and into another, perhaps making what H. Ross Perot called "a giant sucking sound" as jobs and wealth move with it. This special- ization will increase world production, but without any assurance that all the participating countries will benefit. When capital flows abroad, the oppor- tunity for new domestic employment diminishes, which drives down the price for domestic labor. Even if free trade and capital mobility raise wages in low- wage countries (and that tendency is thwarted by overpopulation and rapid population growth), they do so at the expense of labor in the high-wage coun- tries. They thereby increase income in- equality there. Most citizens are wage earners. In the U.S., 80 percent of the labor force is classified as "nonsupervi- sory employees." Their real wages have fallen 17 percent between 1973 and 1990, in significant part because of trade liberalization. Nor does labor in low-wage countries necessarily gain from free trade. It is likely that NAFTA will ruin Mexican peasants when "inexpensive" U.S. corn (subsidized by depleting topsoil, aqui- fers, oil wells and the federal treasury) can be freely imported. Displaced peas- ants will bid down wages. Their land wiU be bought cheaply by agribusiness- es to produce fancy vegetables and cut flowers for the U.S. market. IronicaUy, Mexico helps to keep U.S. com "inexpen- sive" by exporting its own vanishing re- serves of oil and genetic crop variants, which the U.S. needs to sustain its com monoculture. Neoclassical economists admit that overpopulation can spiU over from one country to another in the form of cheap labor. They acknowledge that fact as an argument against free immigration. Yet capital can migrate toward abun- dant labor even more easily than labor can move toward capital. The legitimate case for restrictions on labor immigra- tion is therefore easily extended to re- strictions on capital emigration. When confronted with such problems, neoclassical econo- mists often answer that growth wiU solve them. The aUocation problem of standards-lowering competition, they say, will be dealt with by universaUy "harmonizing" aU standards upward. The distribution problem of faUing wag- es in high-wage countries would only be temporary; the economists believe that growth wiU eventuaUy raise wages worldwide to the fommer high-wage lev- el and beyond. Yet the goal of a sustainable scale of total resource use forces us to ask: What wiU happen if the entire popu- lation of the earth consumes resourc- es at the rate of high-wage countries? Neoclassical economists generaUy ignore this question or give the facile response that there are no lirnits. The steady-state economic paradigm suggests a different answer. The regen- erative and assimilative capacities of the biosphere cannot support even the current levels of resource consumption, much less the manyfold increase re- quired to generalize the higher stan- dards worldwide. StiU less can the eco- system afford an ever growing popu- lation that is striving to consume more per capita. As a species, we already pre- empt about 40 percent of the land- based primary product of photosynthe- sis for human purposes. What happens to biodiversity if we double the human population, as we are projected to do over the next 30 to 50 years? These lirnits put a brake on the abil- ity of growth to wash away the prob- lems of misaUocation and maldistri- bution. In fact, free trade becomes a rec- ipe for hastening the speed with which competition lowers standards for effi- ciency, distributive equity and ecologi- cal sustainability. Notwithstanding those enormous problems, the appeal of bigger free trade blocs for corporations is obvious. The broader the free trade area, the less answerable a large and footloose cor- poration will be to any local or even national community. Spatial separation of the places that suffer the costs and enjoy the benefits becomes more fea- sible. The corporation wiU be able to buy labor in the low-wage markets and seU its products in the remaining high- wage, high-income markets. The larger the market, the longer a corporation will be able to avoid the logic of Henry Ford, who realized that he had to pay his workers enough for them to buy his cars. That is why transnational corpo- rations like free trade and why workers and environmentalists do not. In the view of steady-state econom- ics, the economy is one open sub- system in a finite, nongrowing and materially closed ecosystem. An open system takes matter and energy from the environment as raw materials and returns them as waste. A closed sys- tem is one in which matter constantly circulates internally while only energy flows through. Whatever enters a sys- tem as input and exits as output is called throughput. Just as an organism survives by consuming nutrients and excreting wastes, so too an economy must to some degree both deplete and pollute the environment. A steady-state economy is one whose throughput re mains constant at a level that neither depletes the environment beyond its regenerative capacity nor pollutes it be- yond its absorptive capacity. Most neoclassical economic analyses today rest on the assumption that the economy is the total system and na- ture is the subsystem. The economy is an isolated system involving only a circular flow of exchange value be- tween firms and households. Neither matter nor cncrgy enters or exits this system. The economy's growth is there- fore unconstrained. Nature may be fi- nite, but it is seen as just one sector of the economy, for which other sectors can substitute without limiting over- all growth. Although this vision of circular flow is useful for analyzing exchanges be- tween producers and consumers, it is actively misleading for studying scale- the size of the economy relative to the environment. It is as if a biologist's vi- sion of an animal contained a circula- tory system but not a digestive tract or lungs. Such a beast would be indepen- dent of its environment, and its size would not matter. If it could move, it would be a perpetual motion machine. Long ago the world was relatively empty of human beings and their be- longings (man-made capital) and rela- tively full of other species and their habitats (natural capital). Years of eco- nomic growth have changed that basic pattern. As a result, the limiting factor on future economic growth has changed. If man-made and natural capital were good substitutes for one another, then natural capital could be totally replaced. The two are complementary, however, which means that the short supply of one imposes lirnits. What good are fish- ing boats without populations of fish? Or sawmills without forests? Once the number of fish that could be sold at market was primarily lirnited by the number of boats that could be built and manned; now it is limited by the num- ber of fish in the sea. As long as the scale of the human economy was very small relative to the ecosystem, no apparent sacrifice was involved in increasing it. The scale of the economy is now such that painless growth is no longer reasonable. If we see the economy as a subsystem of a fi- nite, nongrowing ecosystem, then there must be a maximal scale for its through- put of matter and energy. More impor- tant, there must also be an optimal scale. Economic growth beyond that op- timum would increase the environmen- tal costs faster than it would the pro- duction benefits, thereby ushering in an antieconomic phase that impover- ished rather than enriched. One can find disturbing evidence that we have already passed that point and, like Alice in Through the Looking Glass, the faster we run the farther behind we fall. Thus, the correlation between gross national product (GNP) and the index of sustainable economic welfare (which is based on personal consumption and ad- justed for depletion of natural capital and other factors) has taken a negative turn in the U.S. Like our planet, the economy may continue forever to develop qualitative- ly, but it cannot grow indefinitely and must eventually settle into a steady state in its physical dimensions. That condition need not be miserable, how- ever. We economists need to make the elementary distinction between growth (a quantitative increase in size result- ing from the accretion or assirnilation of materials) and development (the qual- itative evolution to a fuller, better or dif- ferent state). Quantitative and qualita- tive changes follow different laws. Con- flating the two, as we currently do in the GNP, has led to much confusion. Development without growth is sus- tainable development. An economy that is steady in scale may still continue to develop a greater capacity to satisfy hu- man wants by increasing the efficiency of its resource use, by improving social institutions and by clarifying its ethical priorities-but not by increasing the re- source throughput. In the light of the growth versus de- velopment distinction, let us return to the issue of international trade and consider two questions: What is the likely effect of free trade on growth? What is the likely effect of free trade on development? Free trade is likely to stimulate the growth of throughput. It allows a coun- try in effect to exceed its domestic re- generative and absorptive lirnits by "importing" those capacities from oth- er countries. True, a country "exporting" some of its carrying capacity in return for imported products might have in- creased its throughput even more if it had made those products domestically. Overall, nevertheless, trade does post- pone the day when countries must face up to living within their natural regen- erative and absorptive capacities. That some countries still have excess carrying capacity is more indicative of a shortfall in their desired domestic growth than of any conscious decision to reserve that capacity for export. By spatially separating the costs and benefits of environmental exploitation, international trade makes them harder to compare. It thereby increases the ten- dency for economies to overshoot their optimal scale. Furthermore, it forces countries to face tightening environmen- tal constraints more simultaneously and less sequentially than would otherwise be the case. They have less opportunity to learn from one another's experiences with controlling throughput and less control over their local environment. The standard arguments for free trade based on comparative advantage also depend on static promotions of efficien- cy. In other words, free trade in tox- ic wastes promotes static efficiency by allowing the disposal of wastes wher- ever it costs less according to today's prices and technologies. A more dynam- ic efficiency would be served by out- lawing the export of toxins. That step would internalize the disposal costs of toxins to their place of origin-to both the firm that generated them and the nation under whose laws the firm oper- ated. This policy creates an incentive to find technically superior ways of deal- ing with the toxins or of redesigning processes to avoid their production in the first place. All these allocative, distributional and scale problems stemming from free trade ought to reverse the traditional default position favoring it. Measures to integrate national economies further should now be treated as a bad idea un- less proved otherwise in specific cases. As Ronald Findley of Columbia Univer- sity characterized it, comparative ad- vantage may well be the "deepest and most beautiful result in all of econom- ics." Nevertheless, in a full world of in- ternationally mobile capital, our adher- ence to it for policy direction is a rec- ipe for national disintegration. ----- End Included Message -----
