Continued from the last post.
Question #5: Would privatization be a free lunch? (See numerous posts at Angry Bear) Economists are trained to be very skeptical of free lunch claims. It's hard to answer yes to that question. However, if it were reworded: are the opportunities for some small efficiency gains? That asks about the same thing but sounds better. (Ok, ok, I'll quit being evasive.) Not much of a free lunch--not to the extent that some claim. Some efficiency gains might be possible, mostly for the very young. This has a lot to do with how people's portfolios will change if there was privatization. It also has to do with Ricardian Equivalence. Here's what I said in January. I was responding to PGL of Angry Bear:
PGL writes that if people already have balanced portfolios, including the bonds implicit in the Trust Fund and their 401(k)s and they suddenly receive the Trust Fund, they will not buy stocks. The implication is that they would buy bonds, effectively replacing the bonds in the Trust Fund and keeping their risk/return ratio the same.
Our logic is pretty much the same. If Social Security was fully funded, I would absolutely 100% agree. But it's not. So I don't. Not 100% anyway. I have to ask myself this question. Suppose the government gave me a $1000 refund on my FICA tax for this year and offered me two options. 1) Give it back to Social Security and forget the whole thing ever happened or 2) buy a $1000 government bond (TIPS, so I don't have to worry about inflation) and keep rolling it over until I retire.
I choose door number 2. In a heartbeat. In other words, I don't think that the bonds implicit in the Trust Fund are the same as a bond in my hand (or my private account). If I did think that they were the same, I wouldn't care--option 1 and option 2 would be equivalent. (UPDATE/CLARIFICATION: It's not by a wide margin that I choose door number 2, but I would choose it. The implication that has for PGL's comment is that while I don't agree 100%, I think he's close. Close enough that there should be more discussion on this point.)
Another reason I'd choose door number 2 that I didn't mention is that I would just like to own the bond myself. Once I own those bonds, would I sell some to buy stocks? I would if my portfolio was previously at a boundary--if I had no stocks and was borrowing constrained. I make the same point in these comments.
No large scale free lunches, but some small scale efficiency gains for mostly young workers. The wealthy and the over-40 set would probably be unaffected. In other words, Ricardian Equivalence would be a good first order approximation. Barro and Becker would be right as a first order approximation.
Question #6: Should private accounts be carved out or added on? I think a carve out would be better if it was done right (sensible assumptions about equity growth, less Draconian cuts). It would also be worse if it was done badly (use your imagination). To have any value, an add-on would have to accomplish something that the present array of 401(k)s and IRAs does not. If it encourages young people to save, it would be better than nothing.
Question #7: What is the significance of 2041? I'll be 69 years old. That's about it.
In other words, the date the trust fund is exhausted is a moving target. (Wasn't it just 2042?) If productivity growth stays healthy and other good things happen, that date will be pushed back. It has been pushed back before. But by the same token, it won't be pushed back to infinity. Since initial benefits are indexed to wage growth, it is harder for productivity gains to push that date back than if initial benefits were indexed to price growth. (See my response to the question on whether or not there is a crisis--it's not a crisis, and 2041 isn't set in stone.)
Closing thoughts: A reasoned debate is still possible. My rationale for these posts is to summarize where I've been and collect my thoughts in one place for my own reference (and yours if you're still listening) as we go into the serious debates on this issue over the summer. If you're still with me after these two posts, you can decide for yourself where I am on the ideological spectrum--I've been called all kinds of things. But I endeavor to be honest. I try to be as consistent as I can be. I love a good discussion of economics, both theory and policy. This has been, and promises to continue to be, both enjoyable and enlightening. As I look back, I haven't changed my position much, but discussions with you, my readers, have refined them.
Thanks to everyone with whom I have discussed these issues through e-mail or blog comments. I look forward to more. Have at it.
