Based on the Chinese government's standpoint, is it logical to impose the trade barrier?

Nowadays, China drives the global economy. So if the trade barrier is reduced, the Chinese economy will go down and affects the economy of the whole world. Do you agree or disagree with this argument

After reading the February 19th, 2009 Economist article, "Turning their backs on the world," do you believe it is wise for world governments to shy away from globalization during a period of economic crisis?

Globalisation

Turning their backs on the world

Feb 19th 2009 From The Economist print edition

The integration of the world economy is in retreat on almost every front

Illustration by Claudio Munoz

THE economic meltdown has popularised a new term: deglobalisation. Some critics of capitalism seem happy about it—like Walden Bello, a Philippine economist, who can perhaps claim to have coined the word with his book, "Deglobalisation, Ideas for a New World Economy". Britain’s prime minister, Gordon Brown, is among those who fear the results will be bad.

But is globalisation really ending? The world’s economies are certainly slowing fast. And the speed and scale of this recession are raising doubts about the assumptions that had underpinned the drive to integrate world markets. At the end of 2008 the IMF said the world economy would grow 2.2% in 2009, less than half the rate in 2007. Now it thinks growth will be just 0.5% this year, the lowest for 60 years. Even that may be optimistic; in the last quarter of 2008, some economies shrank at annualised rates of over 10%.

Nobody ever said globalisation had ended economic ups and downs, but this feels different: prima facie evidence of big problems at least, and possibly of the failure of globalisation to deliver many of its advertised benefits, especially to the poor. True, economic slowdown is not the same as deglobalisation. And the slowdown has yet to affect one thing. For years, poor countries have been growing faster than rich ones; so far, they still are. The gap between real GDP growth in emerging markets and in rich countries widened from nothing in 1991 to about five points in 2007—

and, says the IMF, it will stay at 5.3 points in 2008 and 2009. Helping poorer countries catch up has long been among the benefits touted for globalisation.

And yet the process is going into reverse. Globalisation means the global integration of the movement of goods, capital and jobs. Each of these processes is now in trouble. World trade has plunged. As recently as the first half of 2008, boosted by rising commodity prices and a falling dollar, trade was growing at an annualised 20% in dollar terms. In the second half of 2008, as commodities sagged and the dollar rose, growth slowed fast; by September, says the IMF, it was in reverse. In December, says the International Air Transport Association, air-cargo traffic (responsible for over a third of the value of the world’s traded goods) was down 23% on December 2007—almost double the fall in the year up to the end of September 2001, a result affected by the 9/11 terror attacks.

The downturn has been sharpest in countries that opened up most to world trade, especially East Asia’s tigers. Singapore’s exports are 186% of GDP; its economy shrank at an annualised rate of 17% in the last three months of 2008. Taiwan’s exports are over 60% of GDP; and its economy may fall as much as 11% this year. The downturn has also hurt rich countries that specialise in staid old-fashioned manufacturing—supposedly a safer activity than the reckless delusions of finance. On average, says the IMF, rich countries will contract 2% this year. But Germany and Japan, big exporters of capital goods, cars and electronics, will do worse, their economies shrinking by 2.5% and 2.6% respectively. In the last quarter their economies contracted alarmingly, falling at an annualised rate of 8% in Germany and by 13%—the worst since 1974—in Japan.

Small countries which went into businesses that grew in globalisation’s wake, like tourism, are also suffering. The World Tourism Organisation says international tourist arrivals fell 1% in the second half of 2008, which may not sound bad, but compares with growth of more than 5% a year for the previous four years. In the Caribbean, visitors may fall by a third this season; in some islands hotels are half empty, flights are being cancelled and national budgets, reliant on tourism, are strained.

In contrast, the biggest emerging markets are doing less badly so far. In India, where exports are around 15% of GDP, the government recently said growth in the year to April 2009 would be 7.1%; most forecasters put growth for the 2009 calendar year lower, but still about 5%. In Brazil the economy has been harder hit by falling commodity prices and declining exports. Most economists still think output grew a bit in the year to the fourth quarter, and put growth for 2009 at 1.5% to 2%. China was still growing by 6.8% in the year to the fourth quarter, though like Brazil it is probably stagnating. Chinese exports fell 18% and imports 43% in the year to January. All three countries have large domestic markets and relatively stable banking systems, which have not been liberalised.

The gap between toothless tigers and friskier BICs (ie, BRICs minus Russia, a special case because of oil) raises questions not so much about globalisation as a whole—after all, Brazil, India and China have been beneficiaries—as about particular aspects. Can one be too dependent on trade? How far should one liberalise banking? Is there a trade-off between taking advantage of good times and providing shock absorbers for bad ones?

Emerging markets’ trade problems have been worsened by shifts in capital flows, globalisation’s second big plank. According to the World Bank, net private debt and equity flows to developing countries will fall from $1 trillion in 2007 to $530 billion in 2009, or from 7.7% to 3% of those countries’ GDPs. The Institute for International Finance sees an even steeper fall; it says that this year banks will extract more from emerging markets in debt repayments than they inject in new loans. Bond markets in those countries collapsed in the last quarter of 2008, doing less than $5 billion of business; in the second quarter, they had issued about $50 billion of bonds.

As with trade, financial deglobalisation is hitting countries in a variety of ways. In this case, East Asia has been less affected because most countries there are net creditors. But eastern Europe and Russia have been hammered because local banks went on a foreign-borrowing binge, foreign banks piled into their markets (and piled out again) and because some countries lacked insurance policies against tough times. Although many big emerging markets have built up foreign-exchange reserves and cut their external debts, in eastern Europe reserves have been flat, external debts have risen and current- account deficits have grown considerably in the past decade. In these countries, the reversal of globalisation has exacerbated problems that were building up anyway.

People in emerging markets have mixed feelings about financial liberalisation and may not regret its reversal. But foreign direct investment (FDI) is different. Most people welcome new factories and new jobs. FDI is also one of the commonest routes by which skills and technology are transferred from rich to poor countries.

This, too, is falling. The United Nations Conference on Trade and Development (UNCTAD) says worldwide FDI inflows shrank 21% in 2008 to $1.4 trillion. The World Association of Investment Promotion Agencies says FDI will contract by a further 12-15% this year.

In contrast to trade, the investment impact of the global downturn has so far been hardest on the countries where the woes began: rich ones. They have seen FDI falls of one-third on average and by half or more in Britain, Italy and Germany. Finland and Ireland have seen net outflows. FDI flows to developing countries were still growing in 2008, albeit by only 4%, after a rise of 21% in 2007. Flows to big South American countries were up by about a fifth; those to India more than doubled, though they may ebb as GDP falters.

The third of the three main aspects of globalisation—jobs—is following the other two, with a lag. The International Labour Organisation forecasts that unemployment worldwide will rise by around 30m above 2007’s level in 2009. Most of that rise will be the result of recession, not deglobalisation, but some will be attributable to the fall in trade (exporting companies will lay off workers) and some to declining investment (if expansion plans are cut, new jobs will not be created).

Deglobalisation will have a dire impact on migrants. In the past decade, more people have been moving voluntarily than ever before; now, some are going home. Those who provided labour for the housing boom in America (notably Latinos), Ireland (Poles) and China (rural Chinese going to cities on the eastern seaboard) have been among the first to be laid off. In Spain newly jobless builders are competing with migrants there for jobs picking fruit.

This will surely have an effect on the flow of remittances from rich countries to poor ones, although it has so far (see article) been quite resilient. In any case, economies that absorbed large numbers of foreign workers may take fewer. Some of the millions of South Asians who work in the Gulf, or the young Africans who flock to South Africa, or the Central Asians who work in Russia, may have to stay at home.

Yet for all the economic pain, the social and political fallout from deglobalisation has not yet been severe. Protests may still come. Or maybe national governments are absorbing most of the ire. In December, Greece saw riots after a police bullet killed a teenager. In France, unions brought over 1m people onto the streets for a one-day strike, and a riot in Latvia over economic policy ended in more than 100 arrests. But only in Britain, where workers have picketed refineries and power stations over the hiring of foreigners, has protest had a very anti-global tone.

This lag may be explained by residual support for globalisation, especially in emerging markets. A poll in 2007 by the Pew Global Attitudes Project found that majorities in 47 countries saw international trade as good for them; majorities in 41 out of 46 welcomed multinational firms; in 39 out of 47, most felt better off with a free market. In more than half the countries where changes could be tracked, support for free markets was rising.

When consensus wobbles

But is that still true? Last summer, on the eve of the meltdown, European Union pollsters reported that two-thirds of EU citizens saw globalisation as profitable only for large firms, not citizens. In 2002, according to the Pew poll, 78% of Americans thought foreign trade helped the country; by 2007 it was only 59%. A CNN poll in July 2008 showed that, for the first time, a small majority of Americans saw trade as a threat, not an opportunity.

Of the few worldwide polls to have been completed since then, one by Edelman for the World Economic Forum found that 62% of respondents in 20 countries said they trusted companies less or a lot less now. Manifestly, popular opinion backs more state regulation.

So far, this has mostly taken the form of pouring public money into banks and selected industries, notably cars. Last week Barack Obama set out plans for another vast bank rescue, and the French government promised €6 billion ($7.8 billion) in preferential loans to Renault and Peugeot-Citroën in return for pledges that no car factories would be closed in France.

There has been somewhat less evidence of trade protectionism. India has raised some steel tariffs. The EU has reintroduced export subsidies for some dairy products. Russia has raised import duties on vehicles. But there has also been movement the other way. The American Senate softened the "Buy America" provisions of the stimulus bill. Mexico said that by 2012 it would cut tariffs on thousands of kinds of manufacture. And some countries have sought a safe harbour, rather than embracing pure nationalism. East Europeans are even keener on the shelter of the euro; Iceland has applied to the EU; the Irish are more likely than they were to vote for the EU’s Lisbon treaty.

Despite the downturn, the nations of the world have not shunned globalisation. It has been protected by the belief of firms in the efficiency of global supply chains. But like any chain, these are only as strong as their weakest link. A danger point will come if firms decide that this way of organising production has had its day.

Can you summarize this article and wrtite down some important points regarding GDP?

NEW YORK – Striving to revive the world economy while simultaneously responding to the global climate crisis has raised a knotty question: are statistics giving us the right “signals” about what to do? In our performance-oriented world, measurement issues have taken on increased importance: what we measure affects what we do. If we have poor measures, what we strive to do (say, increase GDP) may actually contribute to a worsening of living standards. We may also be confronted with false choices, seeing trade-offs between output and environmental protection that don’t exist. By contrast, a better measure of economic performance might show that steps taken to improve the environment are good for the economy. Eighteen months ago, French President Nicolas Sarkozy established an international Commission on the Measurement of Economic Performance and Social Progress, owing to his dissatisfaction – and that of many others – with the current state of statistical information about the economy and society. On September 14, the Commission will issue its long-awaited report. The big question concerns whether GDP provides a good measure of living standards. In many cases, GDP statistics seem to suggest that the economy is doing far better than most citizens’ own perceptions. Moreover, the focus on GDP creates conflicts: political leaders are told to maximize it, but citizens also demand that attention be paid to enhancing security, reducing air, water, and noise pollution, and so forth – all of which might lower GDP growth. The fact that GDP may be a poor measure of well-being, or even of market activity, has, of course, long been recognized. But changes in society and the economy may have heightened the problems, at the same time that advances in economics and statistical techniques may have provided opportunities to improve our metrics. For example, while GDP is supposed to measure the value of output of goods and services, in one key sector – government – we typically have no way of doing it, so we often measure the output simply by the inputs. If government spends more – even if inefficiently – output goes up. In the last 60 years, the share of government output in GDP has increased from 21.4% to 38.6% in the US, from 27.6% to 52.7% in France, from 34.2% to 47.6% in the United Kingdom, and from 30.4% to 44.0% in Germany. So what was a relatively minor problem has now become a major one. Likewise, quality improvements – say, better cars rather than just more cars – account for much of the increase in GDP nowadays. But assessing quality improvements is difficult. Health care exemplifies this problem: much of medicine is publicly provided, and much of the advances are in quality. The same problems in making comparisons over time apply to comparisons across countries. The United States spends more on health care than any other country (both per capita and as a percentage of income), but gets poorer outcomes. Part of the difference between GDP per capita in the US and some European countries may thus be a result of the way we measure things. Another marked change in most societies is an increase in inequality. This means that there is increasing disparity between average (mean) income and the median income (that of the “typical” person, whose income lies in the middle of the distribution of all incomes). If a few bankers get much richer, average income can go up, even as most individuals’ incomes are declining. So GDP per capita statistics may not reflect what is happening to most citizens. We use market prices to value goods and services. But now, even those with the most faith in markets question reliance on market prices, as they argue against mark-to-market valuations. The pre-crisis profits of banks – onethird of all corporate profits – appear to have been a mirage. This realization casts a new light not only on our measures of performance, but also on the inferences we make. Before the crisis, when US growth (using standard GDP measures) seemed so much stronger than that of Europe, many Europeans argued that Europe should adopt US-style capitalism. Of course, anyone who wanted to could have seen American households’ growing indebtedness, which would have gone a long way toward correcting the false impression of success given by the GDP statistic. Recent methodological advances have enabled us to assess better what contributes to citizens’ sense of well-being, and to gather the data needed to make such assessments on a regular basis. These studies, for instance, verify and quantify what should be obvious: the loss of a job has a greater impact than can be accounted for just by the loss of income. They also demonstrate the importance of social connectedness. Any good measure of how well we are doing must also take account of sustainability. Just as a firm needs to measure the depreciation of its capital, so, too, our national accounts need to reflect the depletion of natural resources and the degradation of our environment. Statistical frameworks are intended to summarize what is going on in our complex society in a few easily interpretable numbers. It should have been obvious that one couldn’t reduce everything to a single number, GDP. The report by the Commission on the Measurement of Economic Performance and Social Progress will, one hopes, lead to a better understanding of the uses, and abuses, of that statistic. GDP Fetishism - Project Syndicate 2/8/10 4:05 PM http://www.project-syndicate.org/commentary/stiglitz116/English Page 2 of 3 The report should also provide guidance for creating a broader set of indicators that more accurately capture both well-being and sustainability; and it should provide impetus for improving the ability of GDP and related statistics to assess the performance of the economy and society. Such reforms will help us direct our efforts (and resources) in ways that lead to improvement in both.

To secure permission, please contact [email protected]. tvselvakumaran 05:30 30 Sep 09 The official consensus Professor Martin Feldstein's latest article, "The G-20's Empty Promises" on Project Syndicate needs careful consideration. In his article, Professor Feldstein essentially adopts the "official consensus" of the economics profession on the current economic crisis. This official consensus, in its various mainfestations, has also been elaborated on by other famous economists, notably Professor Robert Lucas in his article in the Economist in early August, and by Professor Paul Krugman in his recent article in the New York Times Magazine. One characterizing feature of this official consensus is a confidence (a.k.a. triumphalism) in the certainty of outcomes predicted by modern economic theory. The main precepts of this official consensus are (i) Professor Ben Bernanke, the Chairman of the Board of Governors of the Federal Reserve, has at his disposal all the theoretical tools of economics that are necessary and sufficient to deal with the current economic crisis. As Professor Lucas explains it in his Economist article, if one were able to predict in advance exactly when a market crash would occur, it would imply that the market entertains arbritrage opportunities. Hence, it is not possible to predict financial crises in advance. However, except for the precise timing of the occurrence of financial crises, macroeconomic theory could explain the workings of the economy completely. In particular, to avert the recurrence of the Great Depression, certain actions were needed to be taken by the Fed -- the specifics of these actions were all clearly understood by the economics profession. However, it was politically untenable to take these actions before there was a financial crisis. Once the financial crisis occurred though, Professor Bernanke could intervene in the markets and take the necessary actions (in the Fall of 2008). These actions include the injection of several trillion dollars into the economy and making the availability of credit the cheapest possible. The actions taken by the Fed have now resulted in the economy avoiding a recurrence of the Great Depression. This is, in brief, what Professor Lucas has stated in his Economist article. (ii) Thus in Professor Lucas' interpretation of things, the collapse of Lehman Brothers, for example, was necessary, in order to justify the intervention of the Federal Reserve in the functioning of the markets. The collapse of Lehman Brothers was, although regrettable, an unavoidable event. But, on the whole, monetary policy, even if it is a profligate one, would be necessary and sufficient to prevent the recurrence of the Great Depression, in Professor Lucas' view. Furthermore, the old wisdom of the Chicago School that government should be kept minimal at all times continues to hold, even in light of the current economic crisis. The Keynesians led by Professor Krugman, on the other hand, believe that Lehman Brothers should never have been allowed to fail. In their view, when the Fed's fund rate is at zero, monetary policy is largely ineffective for sustaining and stimulating economic activity. This is because of liquidity traps caused by businessmen who don't see economic opportunities that would induce them to borrow the cheap money available from the banks. Hence the government should step in to provide massive fiscal assistance to the economy by taking on spending directly, even if it means assuming trillions of dollars of public debt. (iii) Professor Krugman scored a lot of points by pointing out that the current state of economic theory, highly influenced as it is by the efficient market hypothesis of the Chicago School, indicated that a crisis of such magnitude as the current economic crisis could not happen at all. This fundamental failure to recognize that an enormous crisis could indeed happen, calls for the overthrow of the policy that markets provide the best social gain when they are completely free from government interference. From first impressions, it might seem that the views of the monetarists and Keynesians are vastly different. However, it is important to note that in the view of the Keynesians too, once large scale government spending as prescribed by the Keynesians is instituted, there is again enough assurance that modern economic theory (although with a heavy Keynesian tilt) would be sufficient to deal with the current economic crisis. (iv) In this regard, perhaps it is relevant to refer here to Professor Robert Shiller's latest article, "Re-inventing Economics" on Project Syndicate. Professor Shiller points out that the free market ideology fails to identify bubbles. Because of the belief that markets know best on all occasions, bubbles cannot occur according to the free market ideology. Professor Shiller's approach pursues a different branch of the Keynesian school of thought than the big spenders. Rather than advocate large government spending to avert a depression, Professor Shiller proposes using techniques from behavioral psychology to predict bubbles in advance. In this way, the socially harmful effects of massive misallocations of capital that arose in the case of the housing bubble or the tech bubble could be prevented in the future. In his other recent article, "Echo Chamber of Boom and Bust" in the New York Times, Professor Shiller elaborates further on the techniques that one could use for studying bubbles. Briefly, the process by which confidence or panic spreads in markets is very similar to the process by which diseases spread among populations. This outlook allows for introducing methods that scientists use to study epidemics into the study of bubbles. (v) The Keynesians have also managed to re-write the conventional wisdom on the advantages of a strong dollar. Through the works of Professors Barry Eichengreen, Jeffrey Sachs and Ben Bernnake, a consensus has developed that attempting to support the gold standard was a major cause for the prolongation of the Great Depression. This has resulted in a viewpoint among economists that a devaluation of the dollar at present would help to reduce global imbalances by restoring the American manufacturing industry. The implications of this viewpoint were analyzed by Professor Feldstein in his July 2009 article "America's Saving Rate and the Dollar's Future" on Project Syndicate, with the conclusion that devaluation of the dollar would necessarily lead to a better future for GDP Fetishism - Project Syndicate 2/8/10 4:05 PM http://www.project-syndicate.org/commentary/stiglitz116/English Page 3 of 3 America. Lost in this new interpretation is the fact that a stable dollar provides many economic benefits for America. The equity premium for American companies taking more risks globally, the transaction charges for providing market making facilities in global markets, and the provisions of liquidity for the currency of international trade are major drivers of economic growth for America, which derive from the dollar being the global reserve currency. (vi) Some other Keynesians have gone beyond questioning just the free market ideology. For example, in his latest article, "GDP Fetishism" on Project Syndicate, Professor Joseph Stiglitz proposes a broad set of economic indicators like health, well-being and sustainability rather than a narrow focus on GDP growth. Yet other developments imply that the rest of the world is steadily moving away from using the dollar as the main reserve currency. To finance this new global reserve system, the IMF has created $250 billion worth of Special Drawing Rights (SDR), and the IMF has indicated its intention to triple this allocation of $250 billion in the future. It would need a strong commitment from the policy-makers in America to re-claim for the dollar its position as the predominant global reserve currency. However, judging from the writings of American economists like Professor Feldstein, it appears that the consensus among professional economists favors devaluing the dollar instead. (vii) The official consensus is a result of a grand compromise between the Chicago School economists and the Keynesians.The conservative economists of the Chicago School would like to avoid the embarassment of getting publicly criticized for the failures of the efficient market hypothesis that this current economics crisis has severely exposed. So famous conservative economists like Professor Lucas have reached out for a consensus by indicating their willingness for a compromise. This compromise involves among other things, (a) foregoing raising concerns about the government's mismanagement of Fanie Mae and Freddie Mac, and (b) lending support to the Fed and the Treasury in their efforts to stabilize the economy, even if the methods that the Fed and the Treasury employ are highly inefficient. What are the Keynesians compromising on? Well, the Western liberal tradition has been intellectually bankrupt ever since the late 1960s. It is only the free market ideology of the Chicago School that has served as the driver of wealth creation in the advanced countries during the last four decades. Hence, the official consensus is a convenient compromise for the Keynesians to avoid asking difficult questions about the future of the Western liberal tradition. Instead, they would like to enact much drama in the media about the resurrection of their hero, John Maynard Keynes. (viii) One other characterizing feature of the official consensus in the economics profession is a collective tendency to "Blame It All On Obama". The conservative economists blame President Obama for not focusing adequately on America's ballooning national debt. The liberals, led by Professor Krugman, fault President Obama for getting distracted from the left's free spending ways by concerns on the size of the fiscal deficit. In the confusion that has ensued, President Obama's own team of economics advisors has fallen back on the official consensus in the economics profession. Availing themselves of the security provided by this official consensus, President Obama's economics team has misled the President thoroughly in economic matters. To begin with, the President is only empowered to administer the nation's affairs for a four year term. The projections put out by the Congressional Budget Office (CBO) for the deficits in the next decade are only a non-authoritative guidance for where the nation's finances would be, if current policies hold for the next decade. Instead, the democrats have been behaving as if the $9 trillion of additional public debt that the CBO projects for the next decade is already a given certainty. In particular, they have not been careful to mention clearly in public discussions how much of this extra spending can be attributed to the President's own spending plans in his current four-year term. Neither have they shown any concerns for taking the Fed and the Treasury to taks for their highly inefficient methods to stabilize the economy. Because of these instances of neglect, the public is not willing to trust the government in financial matters. President Obama has rapidly lost his approval ratings. Professor Lawrence Summers, Professor Christina Romer, Professor Austan Goolsbee and Professor Peter Orszag are directly responsible for this abuse of public trust. (ix) The official consensus has also prevented economists from recognizing that President Obama's universal message of tolerance and justice, which has been received very favorably all around the world, actually opens up vast areas of economic opportunity for America. Unfortunately, it does not matter, for the economists, whether George W. Bush or Barack Obama is in office. The most they can do is re-work their models to favor Keynesian policies, and to argue that the policies they propose arise directly from their number-crunching methods. One might be tempted to attribute this widespread consensus among economists to stick to a narrow theoretical interpretation of the current economic crisis, to the certainty afforded by the mathematical models, which have become indispensible through the course of the 20th century, for the development of economic theory. However, this would be a big mistake. The official consensus in the economics profession is primarily a result of undue influences of power and money. It is much less a result of mathematically based economic theory. In the longterm, this attitude among economists of sticking to an official consensus is going to do serious damage to the American economy. Some other aspects of the official consensus have been explained very well by Professor Kenneth Rogoff in his recent article, "The Confidence Game" on Project Syndicate. I recommend that the reader go through that article. The official consensus is the single largest threat to a robust recovery in the global economy. The official consensus also gravely misinterprets the events of the Great Depression. The implications of this misinterpretation bear directly on the economic health of America.

3) Inequality. On important but irrelevant facts

Here is the article:

Inequality

On important but irrelevant facts

Should we care more about global or national inequality?

Free exchange

Jan 9th, 2014

by R.A. | LONDON

WRITING on Thomas Piketty's new book, Nicolas Goetzmann notes:

I think that Piketty missed something which might be important: Capital is mobile, workers are not, and in the end, we have this: Gini is reducing on a worldwide basis since 2005.

Scott Sumner adds:

I also like Goetzmann's comment about global Gini coefficients. Liberals should care about global welfare. Are they closet nationalists?

These sorts of remarks are common responses to those pointing out that inequality is soaring across the rich world, and they strike me as very problematic.

It is true, of course, that inequality globally has been falling. And it is absolutely right to say that this trend is hugely important and is contributing to a massive rise in global welfare. We should all be ecstatic about it. But in no way does that development excuse us from caring about and worrying about national income inequality, for a few very important reasons.

The first is that it implies, without ever making an actual argument, that efforts to reduce income inequality within rich economies must necessarily slow reductions in global inequality. Why bring up the global statistic unless you are worried that expressions of concern about national inequality are likely to undermine the global trend? Some egalitarian-minded policies might, of course, but many others would not. I'm not sure why someone would want to stake out the position that subsidized pre-school for disadvantaged children is unnecessary, for example, because global inequality is falling.

Second, while we all should care about welfare globally, we should also recognize that the political salience of the issue is exclusively national. To a first approximation, America's Congress does not care in the least about the status of global inequality. There are no sitting congresspersons from Burundi. National inequality, by contrast, is highly politically relevant. Catch-up in the emerging world has a lot to do with innovation and openness in the rich world. If soaring national inequality undermines political support for policies that facilitate innovation and openness, that's a problem for everyone. It's a pretty basic political economy point that globalization will continue while national polities feel that globalization is broadly in their interest. People who like globalization should therefore be very, very concerned when it doesn't appear to be generating broad-based growth in rich countries.

The third is that inequality is growing within emerging markets. One might be inclined to argue that we shouldn't worry too much about that, since rising inequality is a classic side-effect of rapid development which should go away as emerging economies mature. But one of the most important points in Mr. Piketty's book is that the conventional wisdom that development naturally increases and then reduces inequalities is wrong: the data show that there is no systematic tendency for inequality to fall as an economy matures.

And so we should note that the backlash to globalization and development might well come from within emerging markets, and indeed one would have to be fairly cut-off from the news to miss populist expressions of dissatisfaction across the biggest emerging economies over the past couple of years. What's more, Mr. Piketty's work suggests that as the process of catch-up slows inequality trends within countries will begin to dominate inequality trends across countries, leading global inequality to rise once more.

So yes, global inequality has been falling. That is no reason for people of any ideological persuasion to ignore very worrying trends in national distributions of income and wealth.
