Trading up — Jeff Frankel and Rachel Ziemba will be guest blogging this week

I will be away most of this week and will not be posting regularly.

In the interim though, the quality of this blog is likely to go up.

Jeff Frankel of Harvard (who recently started his own blog) has agreed to contribute a few guest posts. And Rachel Ziemba of RGEmonitor -- who co-wrote a series of papers with me on the Gulf’s sovereign funds and contributes to RGE’s economonitor -- will be chipping in as well.

There no doubt will be plenty to discuss.
