New trade theory

However, in the 20th century, an ever-larger share of trade occurred between countries with similar characteristics, which is difficult to explain by comparative advantage. Krugman's explanation of trade between similar countries was proposed in a 1979 paper in the ''

s all over the world; instead, it is concentrated in a few factories and therefore in a few countries (or maybe just one). This logic explains how each country may specialize in producing a few brands of any given type of product, instead of specializing in different types of products.

", which would later feature in his work on the new economic geography. The home market effect "states that, ceteris paribus, the country with the larger demand for a good shall, at equilibrium, produce a more than proportionate share of that good and be a net exporter of it". The home market effect was an unexpected result, and Krugman initially questioned it, but ultimately concluded that the mathematics of the model were correct. When there are economies of scale in production, it is possible that countries may become ' locked into' disadvantageous patterns of trade. Krugman points out that although globalization has been positive on a whole, since the 1980s the process known as hyper-globalization has at least played a part in rising inequality. Nonetheless, trade remains beneficial in general, even between similar countries, because it permits firms to save on costs by producing at a larger, more efficient scale, and because it increases the range of brands available and sharpens the competition between firms. Krugman has usually been supportive of

New economic geography

It took an interval of eleven years, but ultimately Krugman's work on New Trade Theory (NTT) converged to what is usually called the " new economic geography" (NEG), which Krugman began to develop in a seminal 1991 paper, "Increasing Returns and Economic Geography", published in the '' Journal of Political Economy''. In Krugman's own words, the passage from NTT to NEG was "obvious in retrospect; but it certainly took me a while to see it. ... The only good news was that nobody else picked up that $100 bill lying on the sidewalk in the interim."Krugman (1999
"Was it all in Ohlin?"
This would become Krugman's most-cited academic paper: by early 2009, it had 857 citations, more than double his second-ranked paper. Krugman called the paper "the love of my life in academic work".Krugman PR (2008)

, December 6, 2008. Stockholm, Sweden.
The "home market effect" that Krugman discovered in NTT also features in NEG, which interprets

economies of scale In microeconomics, economies of scale are the cost advantages that enterprises obtain due to their scale of operation, and are typically measured by the amount of output produced per unit of time. A decrease in cost per unit of output enables ...
, as Krugman's trade theory argues, then those economic regions with most production will be more profitable and will therefore attract even more production. That is, NTT implies that instead of spreading out evenly around the world, production will tend to concentrate in a few countries, regions, or cities, which will become densely populated but will also have higher levels of income.


Agglomeration and economies of scale

Manufacturing is characterized by increasing returns to scale and less restrictive and expansive land qualifications as compared to agricultural uses. So, geographically where can manufacturing be predicted to develop? Krugman states that manufacturing's geographical range is inherently limited by economies of scale, but also that manufacturing will establish and accrue itself in an area of high demand. Production that occurs adjacent to demand will result in lower transportation costs, but demand, as a result, will be greater due to concentrated nearby production. These forces act upon one another simultaneously, producing manufacturing and population agglomeration. Population will increase in these areas due to the more highly developed infrastructure and nearby production, therefore lowering the expense of goods, while economies of scale provide varied choices of goods and services. These forces will feed into each other until the greater portion of the urban population and manufacturing hubs are concentrated into a relatively insular geographic area.

, Krugman proposed, in an informal "mimeo" style of publication, an "international finance multiplier", to help explain the unexpected speed with which the global crisis had occurred. He argued that when, "highly leveraged financial institutions LIs which do a lot of cross-border investment ... lose heavily in one market ... they find themselves undercapitalized, and have to sell off assets across the board. This drives down prices, putting pressure on the balance sheets of other HLIs, and so on." Such a rapid contagion had hitherto been considered unlikely because of "decoupling" in a globalized economy. He first announced that he was working on such a model on his blog, on October 5, 2008. Within days of its appearance, it was being discussed on some popular economics-oriented blogs. The note was soon being cited in papers (draft and published) by other economists, even though it had not itself been through ordinary peer review processes.


Macroeconomics and fiscal policy

Krugman has done much to revive discussion of the liquidity trap as a topic in economics. He recommended pursuing aggressive fiscal policy and
unconventional monetary policy Monetary policy is the policy adopted by the monetary authority of a nation to control either the interest rate payable for very short-term borrowing (borrowing by banks from each other to meet their short-term needs) or the money supply, often a ...

The debate he started at that time over liquidity traps and what policies best address them continues in the economics literature. Krugman had argued in ''The Return of Depression Economics'' that Japan was in a liquidity trap in the late 1990s, since the

" of the 1990s. He attributes the rise in income inequality in part to changes in technology, but principally to a change in political atmosphere which he attributes to Movement Conservatives. In September 2003, Krugman published a collection of his columns under the title, '' The Great Unraveling'', about the Bush administration's economic and foreign policies and the US economy in the early 2000s. His columns argued that the large deficits during that time were generated by the Bush administration as a result of decreasing taxes on the rich, increasing public spending, and fighting the

"The Great Wealth Transfer"
In 2007, Krugman published '' The Conscience of a Liberal'', whose title refers to Barry Goldwater's '' Conscience of a Conservative''."Nobelpristagaren i ekonomi 2008: Paul Krugman"
, speech by Paul Krugman (Retrieved December 26, 2008) 00:43 "The title of The Conscience of a Liberal ... is a reference to a book published almost 50 years ago in the United States called The ''Conscience of a Conservative'' by Barry Goldwater. That book is often taken to be the origin, the start, of a movement that ended up dominating U.S. politics that reached its first pinnacle under Ronald Reagan and then reached its full control of the U.S. government for most of the last eight years."
It details the history of wealth and income gaps in the United States in the 20th century. The book describes how the gap between rich and poor declined greatly during the middle of the century, and then widened in the last two decades to levels higher even than in the 1920s. In ''Conscience'', Krugman argues that government policies played a much greater role than commonly thought both in reducing inequality in the 1930s through 1970s and in increasing it in the 1980s through the present, and criticizes the Bush administration for implementing policies that Krugman believes widened the gap between the rich and poor. Krugman also argued that Republicans owed their electoral successes to their ability to exploit the race issue to win political dominance of the South.

credited Krugman with a commitment "to accurate history even when some fudging might be in order for the sake of political expediency". In a review for ''The New York Times'', Pulitzer prize-winning historian David M. Kennedy stated: "Krugman’s chapter on the imperative need for health care reform is the best in this book, a rueful reminder of the kind of skilled and accessible economic analysis of which he is capable". In late 2008, Krugman published a substantial updating of an earlier work, entitled ''The Return of Depression Economics and the Crisis of 2008''. In the book, he discusses the failure of the United States regulatory system to keep pace with a financial system increasingly out-of-control, and the causes of and possible ways to contain the greatest financial crisis since the 1930s. In 2012, Krugman published '' End This Depression Now!'', a book which argues that looking at the available historical economic data, fiscal cuts and austerity measures only deprive the economy of valuable funds that can circulate and further add to a poor economy – people cannot spend, and markets cannot thrive if there is not enough consumption and there cannot be sufficient consumption if there is large unemployment. He argues that while it is necessary to cut debt, it is the worst time to do so in an economy that has just suffered the most severe of financial shocks, and must be done instead when an economy is near full-employment when the private sector can withstand the burden of decreased government spending and austerity. Failure to stimulate the economy either by public or private sectors will only unnecessarily lengthen the current economic depression and make it worse.

Krugman advocated lower interest rates (to promote investment and spending on housing and other durable goods), and increased government spending on infrastructure, military, and unemployment benefits, arguing that these policies would have a larger stimulus effect, and unlike permanent tax cuts, would only temporarily increase the budget deficit. In addition, he was against Bush's proposal to privatize social security. In August 2005, after

He has criticized the Obama stimulus plan as being too small and inadequate given the size of the economy and the banking rescue plan as misdirected; Krugman wrote in ''The New York Times'': "an overwhelming majority f the American publicbelieves that the government is spending too much to help large financial institutions. This suggests that the administration's money-for-nothing financial policy will eventually deplete its political capital." In particular, he considered the Obama administration's actions to prop up the US financial system in 2009 to be impractical and unduly favorable to Wall Street bankers.

In anticipation of President Obama's Job Summit in December 2009, Krugman said in a Fresh Dialogues interview, "This jobs summit can't be an empty exercise ... he can't come out with a proposal for $10 or $20 Billion of stuff because people will view that as a joke. There has to be a significant job proposal ... I have in mind something like $300 Billion."

In his June 28, 2010 column in ''The New York Times'', in light of the recent G-20 Toronto Summit, Krugman criticized world leaders for agreeing to halve deficits by 2013. Krugman claimed that these efforts could lead the global economy into the early stages of a "third depression" and leave "millions of lives blighted by the absence of jobs". He advocated instead the continued stimulus of economies to foster greater growth. In a 2014 review of

. " rugman and Obstfeldseem to want to shame students into believing that there are no well-grounded arguments against coercing poor countries into free trade. ... This is poor logic, and pernicious insensitivity." In 1987 he quipped that, "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'." However, Krugman argues in the same article that, given the findings of New Trade Theory, " ree tradehas shifted from optimum to reasonable rule of thumb ... it can never again be asserted as the policy that economic theory tells us is always right." In the article, Krugman comes out in favor of free trade given the enormous political costs of actively engaging in strategic trade policy and because there is no clear method for a government to discover which industries will ultimately yield positive returns. He also notes that increasing returns and strategic trade theory do not disprove the underlying truth of

, Krugman made a significant departure from his general support for free trade, entertaining the idea of a 25% tariff on Chinese imports as a retaliation for China's policy of maintaining a low value for the renminbi, which many saw as hostile currency manipulation, artificially making their exports more competitive. In 2015, Krugman noted his ambivalence about the proposed

He noted that if there is a trade war, imports would decrease as much as exports, so employment should not be strongly impacted, at least in the medium to long run. He believes that the US should not repeat Reagan's 1981 policy on taxes and quotas on imported products, as even if it does not produce a recession, protectionism would shock "value chains" and disrupt jobs and communities in the same way as free trade in the past. In addition, other countries would take retaliatory measures against US exports. Krugman recommended against the abandonment of NAFTA, because it could cause economic losses and disruptions to businesses, jobs, and communities. In the late 2010s, Krugman admitted that the models that scholars used to measure the impact of
globalization Globalization, or globalisation (English in the Commonwealth of Nations, Commonwealth English; American and British English spelling differences#-ise, -ize (-isation, -ization), see spelling differences), is the process of foreign relation ...
in the 1990s underestimated the effect on jobs and inequality in developed countries such as the US. He noted that although free trade has harmed some industries, communities, and some workers, it remains a win-win system overall, enriching both parties to the agreement at the national level; a trade war is equivalently negative for the nations involved, even while it may benefit some individuals or industries within each nation.


Immigration

Krugman wrote in March 2006: "Immigration reduces the wages of domestic workers who compete with immigrants. That's just supply and demand: we’re talking about large increases in the number of low-skill workers relative to other inputs into production, so it's inevitable that this means a fall in wages ... the fiscal burden of low-wage immigrants is also pretty clear."


Green economy

Krugman has called for a transition to a green economy. He supported the

On the Iraq War

Krugman opposed the 2003 invasion of Iraq. He wrote in his ''New York Times'' column: "What we should have learned from the Iraq debacle was that you should always be skeptical and that you should never rely on supposed authority. If you hear that ‘everyone’ supports a policy, whether it's a war of choice or fiscal austerity, you should ask whether ‘everyone’ has been defined to exclude anyone expressing a different opinion."


On Donald Trump

Krugman has been a vocal critic of
Donald Trump Donald John Trump (born June 14, 1946) is an American politician, media personality, and businessman who served as the 45th president of the United States from 2017 to 2021. Trump graduated from the Wharton School of the University of P ...
and his administration. His criticisms have included the president's climate change proposals, economic policy, the Republican tax plan and Trump's foreign policy initiatives. Krugman has often used his op-ed column in ''The New York Times'' to set out arguments against the president's policies. On election night in 2016, Krugman wrongly predicted in a ''New York Times'' op-ed that the markets would never recover under Trump and stated "first-pass answer is never" but retracted the call in the same publication three days later.

Sad!"
