EDITOR'S PICKS:

We've chosen five of this week's best, including Alan Kohler on the advantages of being Wesfarmers, Stephen Bartholomeusz on QBE's pitch, Robert Gottliebsen on BHP's merger strategy, Rob Burgess on decoupling and Martin Wolf of the Financial Times on the trials of regulation.

Wesfarmers' winning hand
Alan Kohler
For most companies, refinancing a huge debt in the current climate would be a nightmare. But for cash-flow rich Wesfarmers, the possibility of an equity raising gives it more bargaining power with the banks.

Avoiding a premium
Stephen Bartholomeusz
QBE has made a name for itself over the years by making smart acquisitions at very good prices. Its approach to rival outfit IAG serves to confirm that.

Get the deal done
Robert Gottliebsen
Rio Tinto and BHP Billiton have played the merger game to perfection. But there's a real danger that unless it draws to a close soon, an altogether different outcome might eventuate.

If the US jumped off a cliff
Rob Burgess
The IMF is keen to point out that Asia has not 'decoupled' from the US. But economic figures emerging from the region tell a very different story.

A question of regulation
Martin Wolf, Financial Times
The regulators are forever doomed to close the stable doors behind financial institutions that always find new and more exciting ways of losing money. But regulation remains a vital component of our system.
