As economies around the world return to growth after the deepest recession in a generation, renewed attention is being paid to enormous fiscal deficits and vast expansions of government debt. This year’s projected deficits as a share of GDP are estimated to be a remarkable 13.5 percent for the US — twice the previous record at the depth of the horrific early 1980s recession — 14.4 percent for Britain, 8.2 percent for France, 8 percent for India, 7.4 percent for Japan, 5.4 percent for Italy, 4.7 percent for Germany, 4.2 percent for China and 2.4 percent for Canada.
In addition to the automatic decline in tax revenues and increase in social-welfare spending during a recession, many nations added large spending increases and/or tax cuts to try to stimulate their economies. The increase in the deficit is the sum of these “automatic stabilizers” and discretionary programs. The discretionary policy response has been largest in the US at a cumulative 4.8 percent of GDP and in China at 4.4 percent between last year and next year, while it has been modest in Germany and Canada and smaller in Britain, France and India.
The automatic increase in the deficit has also been largest in the US, modest in Britain and Germany and smaller in Japan, India, Canada, China, France and Italy. These automatic effects should soon begin to reverse as economic activity recovers, but there is much debate, including at the G8 and G20 meetings, over whether the discretionary stimulus should be extended or ended, repeated or reversed.
Since every dollar, euro, yen, rupee or yuan borrowed today requires the same present value in future interest payments — and therefore future taxes — there are important long-term costs to balance against whatever benefits the deficits create today. There is no fiscal free lunch.
Some politicians, such as US President Barack Obama, herald their fiscal stimulus programs as effective responses to the economic crisis. They pledge allegiance to long-term fiscal responsibility, yet propose budgets with large deficits for years to come and big hikes in the debt-GDP ratio.
Politicians from political parties out of power denounce the deficits and debt as a horrific legacy for our children and an insurmountable burden on the economy. In the US in the 1980s, Democrats excoriated then-US president Ronald Reagan on deficits; Republicans now excoriate Obama on his much larger deficits and debt. Deficits are convenient for politicians as they hide and delay the true tax cost of spending. But when are deficits desirable and when are they damaging?
The impact of the economy on the budget balance is swifter, surer and larger than the impact of the budget balance on the economy. All economists agree that we should allow the automatic stabilizers to work. Discretionary fiscal policy is often clumsy in responding to recession, given the usual lags in legislative and administrative implementation and the politics of pork and special interests surrounding spending and tax decisions.
The US stimulus has been much slower to enter the economy than promised. Indeed, most of the stimulus money will be spent after the recession “appears to have ended,” and the evidence is that so far it has had little effect.
It is appropriate to finance some long-lived public-capital investment by government borrowing, since the benefits will accrue for many years, and future taxpayers might equitably bear part of the burden. This is standard practice for US state and local governments. It is also more efficient to keep tax rates stable over time, and thus to finance with debt temporary large spending needs such as military buildups during war (or to prevent war), while reversing the debt buildup thereafter.
The US federal government’s borrowing exceeded tax revenues in every year since the end of World War II. Such debt finance is both equitable and efficient. But little in the current stimulus programs is justifiable on either of the grounds mentioned above.
The level, composition and growth of spending and taxes are the fundamental fiscal indicators. Even with a balanced budget, there is still the issue of the effectiveness and efficiency of spending, as each dollar of government revenue costs the economy about US$1.30, given the distortions to private decisions caused by taxes.
Large deficits shift the bill for today’s consumption to future generations and can crowd out private investment, thereby slowing the improvement of living standards. Deficits are riskier if the level of the national debt, the accumulation of all previous deficits, is high or rapidly rising relative to GDP.
The debt-GDP ratio varies a lot by country. It will double in the US unless Obama reverses course, as former US president Bill Clinton did when he and a Republican Congress balanced the budget.
Deficits are problematic if they finance consumption, not productive public investment on infrastructure. The crisis funding of the modest delayed infrastructure component of most stimulus programs suggests that much of it would not pass a rigorous cost-benefit test. Some US federal agencies are trying to spend 10 times their previous budgets — not a recipe for efficiency or speed. And deficits can lead to inflation if central banks monetize the government debt, a serious concern in financial markets, as China has warned the US.
These concerns require that fiscal exit strategies be planned, announced and implemented soon, before the stimulus programs become permanently entrenched, develop powerful dependent constituencies and greatly increase the risk of rising interest rates, inflation and taxation. On this score, citizens everywhere, from Boston to Berlin, Mumbai to Moscow, are right to be appalled at the explosion of government debt.

Would China attack Taiwan during the American lame duck period? For months, there have been worries that Beijing would seek to take advantage of an American president slowed by age and a potentially chaotic transition to make a move on Taiwan. In the wake of an American election that ended without drama, that far-fetched scenario will likely prove purely hypothetical. But there is a crisis brewing elsewhere in Asia — one with which US president-elect Donald Trump may have to deal during his first days in office. Tensions between the Philippines and China in the South China Sea have been at
Russian President Vladimir Putin’s hypersonic missile carried a simple message to the West over Ukraine: Back off, and if you do not, Russia reserves the right to hit US and British military facilities. Russia fired a new intermediate-range hypersonic ballistic missile known as “Oreshnik,” or Hazel Tree, at Ukraine on Thursday in what Putin said was a direct response to strikes on Russia by Ukrainian forces with US and British missiles. In a special statement from the Kremlin just after 8pm in Moscow that day, the Russian president said the war was escalating toward a global conflict, although he avoided any nuclear
A nation has several pillars of national defense, among them are military strength, energy and food security, and national unity. Military strength is very much on the forefront of the debate, while several recent editorials have dealt with energy security. National unity and a sense of shared purpose — especially while a powerful, hostile state is becoming increasingly menacing — are problematic, and would continue to be until the nation’s schizophrenia is properly managed. The controversy over the past few days over former navy lieutenant commander Lu Li-shih’s (呂禮詩) usage of the term “our China” during an interview about his attendance
Bo Guagua (薄瓜瓜), the son of former Chinese Communist Party (CCP) Central Committee Politburo member and former Chongqing Municipal Communist Party secretary Bo Xilai (薄熙來), used his British passport to make a low-key entry into Taiwan on a flight originating in Canada. He is set to marry the granddaughter of former political heavyweight Hsu Wen-cheng (許文政), the founder of Luodong Poh-Ai Hospital in Yilan County’s Luodong Township (羅東). Bo Xilai is a former high-ranking CCP official who was once a challenger to Chinese President Xi Jinping (習近平) for the chairmanship of the CCP. That makes Bo Guagua a bona fide “third-generation red”
