Protectionism is the economic policy of restraining trade between states through methods such as tariffs on imported goods, restrictive quotas, and a variety of other government regulations designed to allow (according to proponents) "fair competition" between imports and goods and service produced domestically.
This policy contrasts with free trade, where government barriers to trade are kept to a minimum. In recent years, it has become closely aligned with anti-globalization. The term is mostly used in the context of economics, where protectionism refers to policies or doctrines which protect businesses and workers within a country by restricting or regulating trade with foreign nations.
A variety of policies have been used to achieve protectionist goals. These include:
In the modern trade arena many other initiatives besides tariffs have been called protectionist. For example, some commentators, such as Jagdish Bhagwati, see developed countries efforts in imposing their own labor or environmental standards as protectionism. Also, the imposition of restrictive certification procedures on imports are seen in this light.
Further, others point out that free trade agreements often have protectionist provisions such as intellectual property, copyright, and patent restrictions that benefit large corporations. These provisions restrict trade in music, movies, pharmaceuticals, software, and other manufactured items to high cost producers with quotas from low cost producers set to zero.
Historically, protectionism was associated with economic theories such as mercantilism (that believed that it is beneficial to maintain a positive trade balance), and import substitution. During that time, Adam Smith famously warned against the "interested sophistry" of industry, seeking to gain advantage at the cost of the consumers.
Most mainstream economists agree that protectionism is harmful in that its costs outweigh the benefits and that it impedes economic growth. Economics Nobel prize winner and trade theorist Paul Krugman once stated, "If there were an Economist's Creed, it would surely contain the affirmations 'I understand the Principle of Comparative Advantage' and 'I advocate Free Trade'."
Cambridge University Professor Ha-Joon Chang argues that virtually all developed countries today successfully promoted their national industries through protectionism. Chang points to the significantly high tariffs of the UK, the US and other countries during their process of industrialization. While noting the success of protectionism, Chang has attempted to argue that it would be unfair if the developed countries now re-instituted protectionism by stating that those countries that used protectionist policies during their growth would be trying to "kick away the ladder" from developing countries. In the words of 19th century German economist, Friedrich List:
“It is a very common clever device that when anyone has attained the summit of greatness, he kicks away the ladder by which he has climbed up, in order to deprive others of the means of climbing up after him. In this lies the secret of the cosmopolitical doctrine of Adam Smith, and of the cosmopolitical tendencies of his great contemporary William Pitt, and of all his successors in the British Government administrations. Any nation which by means of protective duties and restrictions on navigation has raised her manufacturing power and her navigation to such a degree of development that no other nation can sustain free competition with her, can do nothing wiser than to throw away these ladders of her greatness, to preach to other nations the benefits of free trade, and to declare in penitent tones that she has hitherto wandered in the paths of error, and has now for the first time succeeded in discovering the truth” 
Protectionists believe that there is a legitimate need for government restrictions on free trade in order to protect their country’s economy and its people’s standard of living.
But that argument is explicitly and essentially premised on capital (and other factors) being immobile between nations. Under the new global economy, capital tends simply to flow to wherever costs are lowest—that is, to pursue absolute advantage." Protectionists would point to the building of plants and shifting of production to Mexico by American companies such as GE, GM, and Hershey Chocolate as proof of this argument.
Protectionists believe that infant industries must be protected in order to allow them to grow to a point where they can fairly compete with the larger mature industries established in foreign countries. They believe that without this protection, infant industries will die before they reach a size and age where economies of scale, industrial infrastructure, and skill in manufacturing have progressed sufficiently to allow the industry to compete in the global market.
Most industrialized governments have long held that laissez-faire capitalism creates social evils that harm its citizens. To protect those citizens, these governments have enacted laws that restrict what companies can and can not do in pursuit of profit. Examples are laws regarding:
Protectionists argue that these laws, adding cost to production, place an economic burden on domestic companies bound by them that put those companies at a disadvantage when they compete, both domestically and abroad, with goods and services produced in countries without such laws. They argue that governments have a responsibility to protect their corporations as well as their citizens when putting its companies at a competitive disadvantage by enacting laws for social good. Otherwise they believe that these laws end up destroying domestic companies and ultimately hurting the citizens these laws were designed to protect.
Protectionism is frequently criticized by mainstream economists as harming the people it is meant to help. Most mainstream economists instead support free trade. Economic theory, under the principle of comparative advantage, shows that the gains from free trade outweigh any losses as free trade creates more jobs than it destroys because it allows countries to specialize in the production of goods and services in which they have a comparative advantage. Protectionism results in deadweight loss; this loss to overall welfare gives no-one any benefit, unlike in a free market, where there is no such total loss. According to economist Stephen P. Magee, the benefits of free trade outweigh the losses by as much as 100 to 1.
Most economists, including Nobel prize winners Milton Friedman and Paul Krugman, believe that free trade helps workers in developing countries, even though they are not subject to the stringent health and labour standards of developed countries. This is because "the growth of manufacturing — and of the myriad other jobs that the new export sector creates — has a ripple effect throughout the economy" that creates competition among producers, lifting wages and living conditions. Economists[who?] have suggested that those who support protectionism ostensibly to further the interests of workers in least developed countries are in fact being disingenuous, seeking only to protect jobs in developed countries. Additionally, workers in the least developed countries only accept jobs if they are the best on offer, as all mutually consensual exchanges must be of benefit to both sides, or else they wouldn't be entered into freely. That they accept low-paying jobs from companies in developed countries shows that their other employment prospects are worse. A letter reprinted in the May 2010 edition of Econ Journal Watch identifies a similar sentiment against protectionism from sixteen British economists at the beginning of the 20th century.
Alan Greenspan, former chair of the American Federal Reserve, has criticized protectionist proposals as leading "to an atrophy of our competitive ability. ... If the protectionist route is followed, newer, more efficient industries will have less scope to expand, and overall output and economic welfare will suffer."
Protectionism has also been accused of being one of the major causes of war. Proponents of this theory point to the constant warfare in the 17th and 18th centuries among European countries whose governments were predominantly mercantilist and protectionist, the American Revolution, which came about ostensibly due to British tariffs and taxes, as well as the protective policies preceding both World War I and World War II. According to a slogan of Frédéric Bastiat (1801-1850), "When goods cannot cross borders, armies will."
Free trade promotes equal access to domestic resources (human, natural, capital, etc.) for domestic participants and foreign participants alike. Some thinkers[who?] extend that under free trade, citizens of participating countries deserve equal access to resources and social welfare (labor laws, education, etc.). Visa entrance policies tend to discourage free reallocation between many countries, and encourage it with others. High freedom and mobility has been shown to lead to far greater development than aid programs in many cases, for example eastern European countries in the European Union. In other words visa entrance requirements are a form of local protectionism.
Since the end of World War II, it has been the stated policy of most First World countries to eliminate protectionism through free trade policies enforced by international treaties and organizations such as the World Trade Organization. Certain policies of First World governments have been criticized as protectionist, however, such as the Common Agricultural Policy in the European Union, longstanding agricultural subsidies and proposed "Buy American" provisions in economic recovery packages in the United States .
Heads of the G20 meeting in London on 2 April 2009 pledged "We will not repeat the historic mistakes of protectionism of previous eras". Adherence to this pledge is monitored by the Global Trade Alert,providing up-to-date information and informed commentary to help ensure that the G20 pledge is met by maintaining confidence in the world trading system, detering beggar-thy-neighbour acts, and preserving the contribution that exports could play in the future recovery of the world economy. Although they were reiterating what they had already committed to, last November in Washington, 17 of these 20 countries were reported by the World Bank as having imposed trade restrictive measures since then. In its report, the World Bank says most of the world's major economies are resorting to protectionist measures as the global economic slowdown begins to bite. Economists who have examined the impact of new trade-restrictive measures using detailed bilaterally monthly trade statistics estimated that new measures taken through late 2009 were distorting global merchandise trade by 0.25% to 0.5% (about $50 billion a year).
