It's starting to look like the Summer of Love. Two reasons: The recovery is taking on a L-U-V shape globally, and it's going to require huge amounts of love and nurturing to keep growth alive.

• L stands for Europe, where slowness to confront deep damage and write down the remaining $500 billion odd in bad bank debt, mean rebuilding will be protracted and painful.
• The United States sports a U, bouncing along bottom right. But its financial giants swallowed harsh medicine early and the U.S. has the flexibility to stage an impressive rebound, if not undone by a fast-rising jobless rate at 9.5 percent and heavily indebted consumers.
• V stands for Asia (ex Japan), the surprise region showing resiliency, thanks to its rapid Q4/Q1 inventory workdown and huge infrastructure spend by China.

Like the Summer of Love 41 years ago, it is a drug-fueled affair. G20 governments are peddling $820 billion in stimulus this year, equivalent to 2 percent of GDP. Central bankers are spending even more. The Fed has doubled its balance sheet to $2.04 trillion the past 12 months.

These actions might have cushioned a severe cyclical downturn but the structural adjustment to a world of costlier credit is only just beginning.

Will politicians and central bankers have the wisdom or the stomach to keep the drug supply going long enough to prevent L-U-V from turning into an ugly W?

Finance ministers and central bankers from the G20 meet this weekend in the English countryside to discuss the world's financial and economic crisis. With this in mind, MacroScope asked a number of economists what they want to see from the meeting and the G20 summit to follow later and what they expect to see.

The answer, in short, appears to be that much is needed but not much expected.

Paul Mortimer-Lee, head of market economics, BNP Paribas:

"There will be progress on agreeing that regulation needs to be more effective and more effectively co-ordinated on a global scale but I am unconvinced we are going to go a long way further.  Some populist posturing on bank bonuses etc should be expected. The less is achieved in other areas the more this will get played up. On bank recapitalisation, they will all agree strong capital is a good thing, but in no way do I expect a concerted plan -- it's driven by events and the exigencies of the local banking system.

"I would like to see progress on the international financial architecture/the IMF and its resources. Maybe we'll get some new facility and some agreement on more new cash ... but a radical overhaul requires the power structure to be rejigged -- more power to the (emerging economies) and less to Europe. This is not something European politicians will want to be high profile when it comes out."

Sarah Hewin, senior economist, Standard Chartered:

"The economic data continue to worsen and markets remain in a state of fear. So the best outcome from the meeting would be a co-ordinated response to frozen credit markets and collapsing global economic activity.

"A wish-list would include announcements on: fixing banking systems, including cleaning up banks’ balance sheets by dealing with toxic assets; more and co-ordinated fiscal stimulus and wider adoption of quantitative easing; expanding the size of the IMF to enable it to support vulnerable countries; and commitments against protectionism.

"But the experience of previous summits is not encouraging - apart from increasing IMF resources and making the right noises on protectionism, we are likely to see few real progressive steps taken."

Gabriel Stein, director, Lombard Street Research:

"The G20 meeting, like almost all summits, is a waste of time. Most of the work will have been done beforehand and the actual meeting could just as well be delegated to functionaries. Its main purpose is political.

"It will issue a bland communiqué telling us that they agree on the need for further reforms and oversight of the world financial system, but that while co-ordination is useful, the actual details are better left to each country/region with its specific issues and problems. It will also warn against protectionism."

Alessandro Bee, economist, Bank Sarasin:

"I would like them to come up with a plan to solve the credit crisis, a coordinated plan. Also apowerful plan with some clear-cut strategies. What we see now is more like a series of individual plans that sometmes materialse and sometimes not.

"I would expect some annoucements rather than real decisions.*

So that's them. What about you? What do you want to see and what do you expect to see?
