Public support for spending cuts is also difficult to win. As a result, many Western policymakers are seeking alternative solutions many of which can be classified as financial repression.

That possibility could arise sometime in the future, when the proverbial brick wall comes into view. But it is not on the horizon yet, which means that there would be no positive private spending response to buffer public spending cuts.

Carlo Cottarelli, appointed by the Italian government to oversee its expenditure review, noted recently that even before spending cuts were enacted, they were being used to finance new spending. The political economy of public spending reform is tricky, and well designed macroeconomic plans can be taken hostage by pork barrel politics.

When Bush asked for spending cuts at the beginning of the year including a social security reform that includes cuts in future benefits world financiers expected that Bush would get his way, or most of it. Little did they appreciate that American voters, having never actually supported spending cuts, would resist.

Partisan disagreement about the proper scope of government remains, but there is no overall rejection of state intervention. Often, it is not interests or ideologies that make public spending cuts unavoidable just facts.

When an economy is suffering from high unemployment and weak aggregate demand, spending cuts are contractionary. Romney conceded this point recently, acknowledging that the fiscal cliff the expiration of Bush era tax cuts at the end of this year, combined with large spending cuts already scheduled to take effect would push the economy back into recession.

He was arguing as Wall Street went into meltdown that the American economy s fundamentals were still strong. McCain s solution seems to be more of Bush s policies tax cuts for the rich plus promises to curb public spending.

Balancing cuts in public spending in order not to endanger growth and employment requires a stable and smart government and time. The UK and Germany are, with their excessive restrictions, are preparing the ground for recessions at home.

In Europe, the United Kingdom, and the US, we are feeling the effects of the unsustainable levels of public and private debt accrued in the years before 2008. Spending cuts are being put in place by governments and households alike, with varying degrees of public acceptance and social unrest.

When an economy shrinks, government debt grows automatically, because its revenues decline and its expenses rise. When it cuts spending, its debt grows even more, because its cuts cause the economy to shrink further.

This in turn had made it possible to increase recurrent public spending in public services.

Even worse, the sequester s across the board spending cuts make no distinction between effective and essential programs and programs that represent special interests or have outlived their original purpose. Such arbitrary cuts are likely to inflict more damage on the economy than sensibly targeted cuts of the same magnitude.

Recent research also reveals that in OECD countries since World War II, successful fiscal consolidation defined as stabilizing the budget while avoiding recession averaged 5 6 of actual spending cuts per dollar of tax hikes. Cuts in spending, especially on entitlements and transfers, were far less likely to cause recessions than tax increases were.

What are the likely costs and benefits of stimulus versus consolidation? And what is the best combination of spending cuts and tax hikes?

Here we have had Republicans criticizing an increase in America s budget deficit after doubling America s national debt in the Bush presidency s eight years. Moreover, Republicans belief that only tax cuts, not public spending, will delivery recovery is a sad example of blinkered ideology.

For example, Ryan supported George W. Bush s spending spree. He also supports maintaining defense spending at or near its current level resisting the cuts that were put in place under the Budget Control Act of 2011.

In a fiscal crunch, the first spending cuts hit productive public investments, because governments prefer to protect current and often inefficient spending on public sector jobs and transfer payments to the private sector. As a result, the global recovery remains anemic in most advanced economies (with the partial exception of the US and the UK) and now also in the major emerging countries, where growth has slowed sharply in the last two years.

Spain has a combination of all three. But, while the specifics differ, the implications are the same all must now endure excruciatingly painful spending cuts.

In Pakistan both the public and private spending on health is low.

Nor do Keynesians think through the kinds of public investments that are needed for them, spending is spending. The result is a public sector vacuum and a dearth of public investments, which in turn holds back necessary private sector investment.

Or public spending all European leaders adamantly want to reduce government spending. But these same leaders, including that supposedly stern mistress of the budget Angela Merkel, were arguing less than two years ago that public spending would provide a Keynesian way out of the crisis.

Spending cuts and revenue increases that have been legislated since 2011 will reduce the projected deficit by 2.4 trillion over the next decade, with three quarters coming from spending cuts, almost exclusively in non defense discretionary programs. Based on current economic assumptions, the US needs about 4 trillion in savings to stabilize the debt GDP ratio over the next decade.

But, they fear that calling for spending cuts will be unpopular, unlike, they hope, demands to balance the budget. For them, the problem with the fiscal cliff is that it does not cut spending enough and raises taxes too much.

Introductory economics used to emphasize the Keynesian multiplier effect recipients of government spending (or of consumer spending stimulated by tax cuts or transfers) respond to the increase in their incomes by spending more, as do the recipients of that spending, and so on. Again, the multiplier is much more relevant under current conditions, because it does not fuel higher inflation and interest rates (and thus crowd out private spending).

When weak aggregate demand causes the economy to operate far below its potential, cuts in government spending enlarge the jobs deficit. Indeed, in his recent speech in Jackson Hole, Wyoming, US Federal Reserve Chairman Ben Bernanke warned that such cuts significantly inhibit job creation.

Anemic government spending, not profligacy, has been a major factor behind the economy s lackluster recovery. According to a recent report by the Congressional Budget Office, large spending cuts by state and local governments and, more recently, a significant reduction in federal spending have contributed to the unusual and prolonged weakness of aggregate demand.

Indeed, the deflationary spiral, particularly in Greece and Spain, is causing output to contract so rapidly that further spending cuts and tax increases are not reducing budget deficits and public debt relative to GDP. And Europe s preferred solution more austerity is merely causing fiscal targets to recede faster.

The Keynesian prescription is simple If the economy is weak, fiscal policy should be used to stimulate it if it is overheating, spending cuts or tax hikes should be used to cool it down. Public debt levels will rise and fall, but policymakers should not pay too much attention.

The results of austerity have been what any Keynesian would have expected hardly any growth in the UK and the eurozone in the last two and a half years, and huge declines in some countries little reduction in public deficits, despite large spending cuts and higher national debts.

Crisis and management is a key function of public administration, and it cuts across service delivery and delivery functions.

Cut public sector spending directly, while creating incentives to induce lower private sector expenditure.

It has no economic justification. In the long run, additional targeted spending cuts will be necessary as part of a balanced package to stabilize the debt GDP ratio.

A large scale public investment program would stimulate employment in the short term, and growth in the long term, leading in the end to a lower national debt. But financial markets demonstrated their shortsightedness in the years preceding the crisis, and are doing so once again, by applying pressure for spending cuts, even if that implies reducing badly needed public investments.

Fiscal consolidation means less public spending. And less spending means less upward pressure on prices which is the last thing Europe needs in a deflationary environment.

The Center on Budget and Policy Priorities finds that almost two thirds of the Ryan budget s spending cuts would come from such programs. Romney offers few specifics, but simple arithmetic shows that his plan would require even deeper cuts in these programs than Ryan s plan would.

Will 2010 see a recovery shaped like a V or a W, or will there simply be an anemic tilt towards a very distant prospect of better times? I suspect the latter, with unemployment and cuts in public spending certainly in much of Europe and the United States constraining economic confidence.

And one of the first victims of difficult economic times, I think, is public spending of any kind, but certainly in the firing line at the moment is public spending for science, and particularly curiosity led science and exploration.

Yes, there will be big spending cuts which will hit defense contractors, doctors with Medicare patients, and all who benefit from or rely on government discretionary spending and substantial tax increases. But, to balance the budget in the long run, either taxes have to go up or spending has to go down relative to some baseline, or both.

Beyond improving public accounts, a large part of the revenues from high commodity prices were used to increase public spending, although this proportion varied from country to country. At one extreme stands Argentina, with the largest increase in public spending relative to GDP in Latin America (almost ten points).

Spending cuts and tax increases that in the long run restore fiscal sanity and balance are good. Having them all hit a weak, still depressed economy simultaneously is not good.

At first glance, one might think that lowering taxes would make people happier, because having more disposable income increases their wellbeing. But other factors can also come into play, such as whether the tax cuts are perceived as fair and whether they are accompanied by unpopular spending cuts.

Until now, the diplomatic effort to prevent dangerous climate change has focused on coordinating national cuts in greenhouse gas emissions. But what is needed is more spending, not just more coordination.

America s gravest fiscal problem is the short and medium run deficit between tax revenues and spending. This deficit is entirely of Bush s own creation, having enacted and now seeking to extend tax cuts that are not cuts at all, because they merely shift the burden of fiscal consolidation onto future generations.

Why? It cuts fuel poverty, it cuts their bills, and it cuts carbon emissions at the same time.
