nTEXT A Whiff of the 1930sA Whiff of the 1930s IN THE SPRING of 1931 Austrias largest bank,the Credit Anstalt,was on the verge of collapse.The Austrian government could not simply stand by and let it fail,but when it came to the banks rescue with large sums of freshly printed domestic currency,the resulting capital flight rapidly depleted Austrias gold and foreign exchange reserves.The obvious answer would have been to abandon the gold standard and let the currency float.But this solution was unacceptablenot just because a drop in the schillings value would magnify the burden of foreign-currency-denominated debt,but because a currency devaluation would deal a devastating blow to the confidence of a country whose memories of post-World War I hyperinflation were still fresh.Austria pleaded for help from its neighbors and the then-new Bank for International Settlements,but the offered assistance was too little,too late.In the end,the desperate government resorted to capital controls.Unit SixThe Return of Depression EconomicsPaul Krugman It is a familiar story to economic historians.It is also astonishingly modern-sounding:if the plot does not exactly fit any one of todays crisis-ridden economies around the world,it does sound very much like a pastiche of recent events in Indonesia,Malaysia,and Brazil.The main difference now is that financial rescue attempts from the international community have become routine.When a country gets in trouble today a SWAT team from the International Monetary Fund and the U.S.Treasury quickly arrives on the scene.Suppose,however,that the IMF could use a time machine to send its best money doctors back to that Vienna spring of 1931,but without the ability to offer a huge,no-questions-asked credit line on the spot.What would todays experts say?What could they tell the Austrians that they did not already know?Unit SixThe Return of Depression EconomicsPaul Krugman Most modern economiststo the extent that they think about it at allregard the Great Depression as a gratuitous,unnecessary tragedy.They believe that what might have been an ordinary,forgettable recession became a nightmarish slump thanks to the stupidity(or at least the ignorance)of policymakers.If only the Federal Reserve had not been preoccupied with defending the gold standard instead of the real economy;if only Herbert Hoover had followed an expansionary fiscal policy instead of trying to balance the budget,if only policy in general had not been governed by a“liquidationist”philosophy that saw short-run economic pain as a necessary purgative for previous excessesthen the catastrophe could easily have been avoided.And since we know better now,it cannot happen again.Unit SixThe Return of Depression EconomicsPaul Krugman Or can it?As little as two years ago I and most of my colleagues were quite confident that although the world would continue to suffer economic difficulties,those problems would not bear much resemblance to the crisis of the 1930sbecause economists and policymakers had learned the lessons of that decade and would never again perversely tighten monetary and fiscal policy in the face of recession.True,Mexico suffered a severe slump in 1995 and Japans economy had stagnated since 1991,but these appeared to be special cases,easily rationalized as the result of exceptionally misguided policy.Perhaps we should have known better and realized,for example,that the dilemma Austria faced in 1931 could just as easily arise in the modern world,and that now as then there are no good answers.In any case,there is no mistaking the lesson of the terrifying economic and financial events of the last two years:Unit SixThe Return of Depression EconomicsPaul Krugman the economic crisis in Asia,its spread to Latin America,the deepening slump in Japan,and the brief but ominous panic that swept bond markets last autumn.The truth is that the world economy poses more dangers than we had imagined.Problems we thought we knew how to cure have once again become intractable,like temporarily suppressed bacteria that eventually evolve a resistance to antibiotics.More specifically,the problem of aggregate demandof getting people to spend enough to employ the economys productive capacityis not,as we might have thought,always a problem with an easy solution.While it may often be possible for countries,especially large,stable,self-sufficient economies like the United States,to handle recessions simply by printing more money,we are finding an increasing number of cases in which countries find either that they cannot apply that same medicine or that the medicine is ineffectual.There is,in short,a definite whiff of the 1930s in the air.Unit SixThe Return of Depression EconomicsPaul Krugman The point is not that all of the current economic difficulties will necessarily get worse.There is a reasonable chance that 1999 will see some economic recovery in Asia,if not the beginning of a real climb back to economic health.Through prompt Federal Reserve action(and luck),the United States managed to avoid a financial panic last fall.Even Japan could do better in 1999 than it did in 1998.But even if all the current crises are weathered,the mere fact that they could happenand that conventional policy responses have turned out to be either ineffectual or unavailableis an ominous warning.The problems of the 1990s have distinct similarities with the problems of the 1930s;so do the solutions.We had better all start relearning our Depression economics.Unit SixThe Return of Depression EconomicsPaul Krugman Its the Short Run,Stupid Its the Short Run,Stupid BEFORE THE 1930s most economists regarded the business cyclethe alternation of recessions and recoveriesas a relatively minor issue.Whatever the causes of such fluctuations,economists believed that slumps were self-correcting and that the economy always tended to restore full employment in the long run.Hence,the fundamental economic problem was to ensure that resources were used efficiently,not to ensure that they were used at all.True,as early as 1923 John Maynard Keynes famously took his colleagues to task,admonishing them not to ignore the short run:Unit SixThe Return of Depression EconomicsPaul Krugman This long run is a misleading guide to current affairs.In the long run we are all dead.Economists set themselves too easy,too useless a task if in tempestuous seasons they can only tell us that when the storm is long past the sea is flat again.But not until the Great Depression did economists realize that“short run”shortfalls of demand were crucially important.Perhaps slumps were still selfcorrecting in the long run,but would the economy survive to reach that long run?Given the experience of the Depression,one might have thought that classical economics was gone for good.But the success of Keynesian economics in damping down the business cycle meant that the old focus on the fullemployment long run could reemerge with a new justification.It was once againUnit SixThe Return of Depression EconomicsPaul Krugman reasonable to assume that the economy would always tend quickly back to full employmentnot because of any automatic mechanism but because intelligent policymakers would use monetary and fiscal policy to get it there.Like traditional European wine grapes that survived the great phylloxera epidemic by being grafted onto American-root stock,classical economic theory survived the Great Depression by being grafted onto the assumption that activist monetary and fiscal policy would ensure more or less full employment.In the 1950s Paul Samuelson dubbed the resurrection of classical full-employment economic theory the“neoclassical synthesis.”It remains to this day the position of those who appreciate but do not worship free markets.Here,for example,is what I wrote in Slate two years ago in an article entitled“Vulgar Keynesians”:Unit SixThe Return of Depression EconomicsPaul Krugman In reality the Federal Reserve Board actively manages interest rates,pushing them down when it thinks employment is too low and raising them when it thinks the economy is overheating.You may quarrel with the Fed chairmans judgmentyou may think that he should keep the economy on a looser reinbut you can hardly dispute his power.Indeed,if you want a simple model for predicting the unemployment rate in the United States over the next few years,here it is:It will be what Greenspan wants it to be,plus or minus a random error reflecting the fact that he is not quite God.But putting Greenspan(or his successor)into the picture restores much of the classical vision of the macroeconomy.Instead of an invisible hand pushing the economy toward full employment in some unspecified long run,we have the visible hand of the Fed pushing us toward its estimate of the noninflationary unemployment rate over the course of two or three years.Unit SixThe Return of Depression EconomicsPaul Krugman To an adherent of the neoclassical synthesis like myself,then,the really disturbing thing about the worlds current problems is not so much the possibility that they will spiral into a new Great Depression,which still remains unlikely and indeed seems to have receded in the last few months.Instead,the problem is that for the first time since the 1930s,we cannot be sure that governments can or will increase demand when we need it.The Unholy Trinity The Unholy Trinity WHAT HAS gone wrong?On the face of it,there seem to be two quite separate issues:the problems of developing countries threatened with hot money flows and those of mature economies facing a“liquidity trap.”Unit SixThe Return of Depression EconomicsPaul Krugman As the Bretton Woods system of fixed exchange rates that had governed postwar world monetary affairs began to show signs of strain in the 1960s,a number of economists began to argue that there was a fundamental dilemmaor,more precisely,a“trilemma”at the heart of international finance.Analysts such as the Canadian theorist Robert Mundell suggested that,as a fundamental matter of economic logic,countries could not get everything they want and that any exchange rate system involves sacrificing some important objectives to achieve others.Three conflicting objectives in particular,sometimes dubbed the“irreconcilable trinity,”have preoccupied would-be international financial architects.First,countries would like to retain scope for independent monetary policythat is,they would like to be able to cut interest rates to fight recessions and raise them to counter inflation.Unit SixThe Return of Depression EconomicsPaul Krugman more or less stable exchange rates because erratic fluctuations in the value of their currency create uncertainty for business and can sometimes cause severe disruptions to the financial system.Third,countries would like to maintain full convertibilitythat is,they would like to assure businesses that money can be freely moved in or out of the country,if only to avoid the bureaucracy,paperwork,and opportunities for corruption inevitably associated with any attempt to limit capital movements.Alas,these objectives are indeed irreconcilable.The iron law of international finance is that countries can achieve at most two of the three.The logic of this law becomes apparent when one considers what happens if a country tries to have it all.Suppose that a country,like the members of the European Monetary System,were to maintain free capital mobility and also commit itself to keeping its exchange rate fixed,buying or selling its currency on the foreign exchange markets as necessary.Unit SixThe Return of Depression EconomicsPaul Krugman Could it cut interest rates to fight a recession?Not for long.If France were to try reducing its interest rates below German levels,investors,knowing that the exchange rate was fixed,would see a profit opportunity in the“carry trade.”That is,they would borrow in French francs,exchange the proceeds for Deutsche marks,and invest them in Germany.To prevent this increased supply of francs and demand for marks from driving down the value of its currency,the Bank of France would have to sell marks while buying francs itself.Even if the bank started with tens of billions of marks in its account,it would quickly find those reserves exhausted.At that point a choice would have to be made.France would either have to give up on its attempt to cut interest rates and abandon the goal of independent monetary policy,or let the franc drop and give up on the goal of exchange rate stability.Alternatively,it could impose some kind of capital controls,limiting investors ability to convert francs into foreign currency.Unit SixThe Return of Depression EconomicsPaul Krugman The trilemma of international finance forces countries to choose among three basic exchange regimes:a floating exchange regime,which allows complete freedom of international transactions and lets the government use monetary policy to fight recessions at the cost of erratic fluctuations;a fixed rate,which purchases stability at the expense of monetary independence;or capital controls,which can reconcile a relatively stable exchange rate with some monetary independence but only at the cost of other problems.Since World War I broke up the classical gold standard,all of these regimes have been tried repeatedly.The conventional wisdom about which regime is most desirable has itself gone through cycles.But two years ago the majority opinion among economistsand less decisively in the international policy communitywas clearly in favor of floating rates.There had once been considerable sympathy for attempts to limit exchange rate variation:for example,the“adjustable pegs”of the Bretton Woods Unit SixThe Return of Depression EconomicsPaul Krugman era,under which rates were normally held within narrow bands but adjusted on occasion as circumstances warranted.But experience showed that the mere hint of a possible devaluation in the face of highly mobile capital provoked massive speculative attacks.So such compromise systems broke down,with countries either giving up and floating their rates or averting speculation by ruling out any possibility of future changes in currency values.And that meant that adopting any sort of fixed exchange rate required in effect giving up completely on monetary adjustment.Hong Kong offers a classic example.Economic turmoil in the rest of Asia and the devaluation of many neighboring countries currencies have left Hong Kong clearly overpriced and led to record unemployment.No law would prevent the textbook solutiona one-time devaluation of the Hong Kong dollar.But the citys economic authorities have concluded that the only way to prevent massive speculation against that currency every time there is an economic downturn is to commit themselves firmly to keeping its value in U.S.dollars constant.A recession must therefore simply be endured.Unit SixThe Return of Depression EconomicsPaul Krugman A country could avoid locking its exchange rate by reinstituting capital controls of the kind that prevailed for the first two decades of Bretton Woods,which allowed the pegs of that system to be truly adjustable,but the costs of such controls seem a high price to pay.A freely floating exchange rate,then,appears to be the lesser of three evils.Even economists who are generally pro-floating agree that tightly integrated regions that form“optimal currency areas”should adopt the ultimate form of fixed exchange rates,a common currency.(Whether the new eurozone constitutes such an area is another question.)But as a general rule,the preferred alternative of most economists is a floating exchange rate.In particular,it is the one most consistent with the neoclassical synthesis,because it leaves countries free to pursue both free-market and full-employment policies.(from Foreign Affairs,January/February 1999)Unit SixThe Return of Depression EconomicsPaul KrugmanExercisesn.Translate the following into English,using the
