There was a bit of good economic news last week, with the announcement that U.S. retail sales rose 0.8 percent in July. That was the biggest gain since February, and well above the 0.3 percent that economists had predicted. So is the economy finally recovering?

Over the last five years, the word "hedge" has become something of a dirty word. Think hedge funds - those massive, unregulated accumulations of capital that played a key role in bringing about the Great Recession. The idea of protecting oneself against adverse economic conditions seemed sound, but it quickly mutated into a bewildering flurry of transactions that ended up creating more risk than they were designed to mitigate. What's more, the original concept behind hedge funds became watered down to the point that many today aren't really "hedging" against anything. They're simply a means for investors to park their money with a trusted fund manager who might or might not repay that trust in the form of steady returns - all with minimal regulatory oversight.

Nearly all major ocean carriers have announced plans to stop providing chassis to U.S. truckers at key shipping locations. But it's far from clear how that decision will play out.

What's in store for the U.S. and global economy? To Walter Kemmsies, chief economist of engineering firm Moffatt & Nichol, the next few years will bring "the good, the bad and the ugly."

Supply chains are just as susceptible to faddish behavior as anything else. We're social animals, so we tend to follow the crowd - especially if we believe that the crowd has a competitive edge. That's why so many companies flocked to China over the last couple of decades, in search of ever-cheaper sources of production. Or why outsourcing became such a hot trend over that same period of time.

We like the term "supply chain" because it suggests a tightly interlinked series of steps that results in the uninterrupted flow of product from the raw-materials stage all the way to the consumer. But the word "chain" also evokes a burden, and that's how many companies have come to view their operations in recent years. Hence the mania for outsourcing everything from design and manufacturing to logistics.
