Company attitudes toward social media sites vary. Some swing the doors wide open, allowing employees to tend to their Facebook farms and update Twitter statuses throughout the day. Others lock 'em down, keeping non-business site access to a minimum.

A recent study found that, in the United States, 77% of employees with Facebook accounts check in with the community from the office. And, the amount of time they're spending in this part of the online world is growing. In the United Kingdom, another study found that 57% log in regularly from work, costing their employers 40 minutes a day.

Philip Wicks, a consultant at Morse PLC, a technology research firm in London, "It isn't just something you can do for half an hour during a lunch break but all through the day and because of that, it has a huge impact because people aren't necessarily concentrating on what they should be doing during the day." He estimates that this translates to lost productivity of $2.25 billion a year.

It seems like the obvious move would be to block the sites, but William Beers of PricewaterhouseCoopers disagrees. "Instead of trying to shut it down, I think we should try to embrace these technologies, put in a nice policy that governs it and explain to users the risks related to it, provide some training and then see what business benefits we can have from it," he said.

Recession or not, people can't walk around naked ... especially not in the United Kingdom. (Iceland in summer? Fair game.) Marks & Spencer Group Plc (London: MKS:UK), the largest clothing retailer in the country, just sustained its smallest drop in sales in nearly two years thanks to some savvy deals (offered to consumers) and warm weather. After making their dollars pounds stretch for so long, shoppers were finally ready for a bit of style.

Revenue declined a modest 1.4% for the year so far, much better than the 2.5% average estimate offered by 16 analysts. This was good enough to push M&S shares up 4%. If all goes well, same store sales may start to increase soon, which means that a full recovery will be right around the corner. Same store sales have fallen for the past seven quarters, and company cut its dividend for the first time in almost a decade.

The discounts that helped lead to the recent M&S sales performance are responsible for 18% of the company's food sales (which are down 0.5% on for same store) – much better than the 2.4% estimate. General merchandise fell only 2.4%, beating the 3.5% projection handily.

Macroeconomic guru Jim Rogers has a message for investors: The United Kingdom is finished.

Bloomberg quotes the bow tie-clad forecaster as saying that he "would urge you to sell any sterling you might have. It's finished. I hate to say it, but I would not put any money in the U.K."

But England isn't the only country Rogers is trashing. Reuters reports that Rogers is accusing the United States of a systematic effort to devalue the dollar by "turning on the printing presses." It's hard to argue with that and he went on to say that "The idea that you can fix a period of excess borrowing and excess consumption by more borrowing and more consumption to me is just ludicrous."

He reiterated his bullishness on China's long-term future even though that market has been hammered of late.

Regardless of whether you buy into his investment theses, it's hard to argue with his logic that borrowing and consumption will not lead out of a nightmare created by borrowing and consumption.

Carlton Delfeld reveals his latest global ETF picks and warns of leveraged funds.

Q. Carlton, in your last newsletter, you commented on the low valuations of several global markets, including Ireland, Singapore, UK, and Sweden, among others. Have you since added any ETFs from these regions to your portfolios?

A. Yes, I have added iShares MSCI South Africa Index (NYSEArca: EZA), iShares MSCI Singapore Index (NYSEArca: EWS), and the iShares MSCI United Kingdom (NYSEArca: EWU). South Africa is in part a currency and commodity play. The United Kingdom is very much predicated on global financial recovery, and Singapore will likely be a core holding.

Q. Each of these regions seems to have its own stress points right now. Do you think that South Africa is particularly vulnerable to a global slowdown? Hasn't Singapore been hit hard by the bear market in China? And isn't the UK just moving into a housing decline that may rival that of the US?

A. South Africa, China and the UK are all trading at attractive valuations. They all have challenges. The South Africa Rand has been a strong currency and will come back with higher gold prices, the UK is already moving through the housing issue and its financial-oriented market has already been hammered. Lastly, Singapore is a very high-quality China play.

Cheerio! What to do if you're a 54-year-old former world leader, in good health, with Western sympathies? Days of leading a major country are behind you, but you're not ready to pack it in anytime soon. Link up with a major American corporation, of course! Tony Blair, who served as Great Britain's prime minister from 1997 through June of last year, has agreed to join with JPMorgan Chase (NYSE: JPM) in the role of part-time adviser.

The financial terms of the arrangement weren't disclosed, but one Manhattan recruitment consultant estimated in The Financial Times that Blair's fee would likely be more than $1 million a year (though that sum doesn't go quite as far in pounds these days).

In a surprise decision, the European Central Bank Thursday left its key interest rate unchanged, keeping its refinance rate a 4% due to inflation risks.

Confounds chatter

The ECB's decision went against growing chatter in Wall Street circles Wednesday that the ECB, the Bank of England and the U.S. Federal Reserve would all cut short-term interest rates, as well as implement other coordinated measures, to counteract the contraction effects of subprime mortgage and related asset defaults on the world's largest industrialized economies, the European Union and the United States.

"The decision to stay flat was a bit of a surprise, but that doesn't mean there won't be a future cut," Andrew Resnick, independent currency trader, told BloggingStocks Thursday. "I think we'll still see coordinated action by the ECB and the Federal Reserve to maintain liquidity and keep overnight rates at typical levels. Also keep in mind that the Bank of England cut its rate, so maybe they're doing it sequentially to prepare the market for the new monetary policy."

Recent reports highlight U.S. investors' strong and continuing interest in foreign markets. In many cases, cash is being invested indirectly, often through exchange-traded funds (ETFs) that mirror the currency-adjusted performance of publicly-traded shares in countries around the world.

While there are any number of fundamental reasons for choosing one nation's equity market over another, sometimes interesting opportunities crop up that seem, at first glance anyway, mainly technical in nature.

A comparison of the relative performance of the country funds for the United Kingdom and Germany, both based in Europe and subject to a number of the same macroeconomic influences, would seem to suggest such an opportunity.
