As every school child knows, water is formed by the two elements of hydrogen and oxygen in a very simple formula we all know as H2O. Today we start a series that starts with the question, What are the elements that comprise deflation? Far from being simple, the "equation" for deflation is as complex as that of DNA. And sadly, while the genome project has helped us with great insights into how DNA works, economic analysis is still back in the 1950s when it comes to decoding deflation. Notwithstanding the paucity of understanding we can glean from the dismal science, in this week's letter we will start thinking about the most fundamentally important question of the day: is inflation, or deflation, in our future?

But quickly, I want to thank the many people who wrote very kind words about last week's letter. Many thought it was one of the better letters I have done in a long time. If you did not read it, you can read it here. And of course, you can go there and sign up to get this letter sent to you each week for free. Why not become of my 1 million (plus and growing) closest friends?

Among the economists and writers I regularly read, there are some who, if they agree with me, I go back and check my assumptions - I must have been wrong. Paul Krugman is one of those thinkers. I admit to his brilliance, but his left-leaning philosophy does not particularly square with mine, and I find that most of the time I disagree.

That being said, I strongly encourage you to read his essay in the New York Times Magazine, which comes out this weekend. It is worth the high price of the Times to read it, if you can't get it online. It is a very hard critique and analysis of the failure of current macro and financial economic thought, which didn't even come close to predicting the current financial malaise. Indeed, as he points out, most schools of thought said the state we are in could not happen.

Last week we began a series on data abuse, about how various commentators twist and torture data to make it say what they want, or fail to look at the details underneath the headlines. Predictably, there is a lot of fodder this week as we forge ahead into this ripe territory. The headlines screamed that US income data went up unexpectedly. Green shoots were everywhere. But if you look at the actual data, you find something much different. And, I keep hearing the insistent refrain that the market is telling us that the recovery is around the corner. Well, the recovery may be, but can the market really tell us that? I have about 25 windows open in my computer, with tons of misleading data. Let's see how much we can cover in this week's letter.

But first, I want to focus your quick attention on a new "Conversation" I will have next Monday. (For those readers who are new, I have a subscription service where I hold conversations with friends on a variety of current topics. I am gratified that it's getting rave reviews.)

I have been writing about the New Normal of late, and for my next Conversation I have invited two of the sharpest analysts I know to talk about what the New Normal will look like.

What levels do we get to? What does the world economy look like? What will the path to recovery look like? And so on! David Rosenberg , former chief economist for Merrill Lynch, one of the few mainstream analysts who got it right (now with Gluskin Sheff in Toronto) and the brilliant Michael Lewitt of Harch Capital Management, someone who was writing about the credit crisis long before it happened, are both deep thinkers, and both have strong ideas about how our future will unfold. I can't wait to get them at the same table and see if we can flesh out a few concrete ideas.
