Sovereign Debt and Drive-In Movies, Part I

In Eco 101 you probably learned that one of the big issues that arises whenever there is an effort at collective action in the absence of a central authority is the free-rider problem, otherwise known as "positive externalities."

Let's go over it again, because some of us (myself included) have allowed our memories of Eco 101 lessons to become ... less than fresh.

Textbook analogy: An entrepreneur creates a drive-in movie theatre, because it is cheaper just to put up a screen than to build a whole building. At first things work fine but over time cinephiles discover that they don’t have to drive into the entrepreneur’s lot and pay him in order to watch the movie: they can enjoy the same movie for free by parking on the opposite side of the street. The entrepreneur either internalizes the benefit (puts up walls) or he goes out of business.

So external benefits, that is, benefits available to freeloaders, threaten the viability of the whole enterprise.

That is one view of the recent and ongoing controversy over Argentine bonds. In the case of a distressed sovereign nation, the analog of the desirable movie-going experience is an efficient, reliable restructuring of those debts, the sort of thing that successful bankruptcy proceedings provide in the corporate/domestic context. In such a restructuring, on the sovereign level, many bondholders have to be willing to accept a haircut on their bonds in return for continued predictable payments of the interest.

But there are always holdouts, who are in the position of the folks outside the drive-in grounds. So: what to do?

Many people have drawn the usual Eco 101 lesson. You need a sovereign. In this case, you need a sovereign for the sovereigns. You need some international organization to do what bankruptcy courts do, while doing at the same time what walls do for an indoor theatre.   

There have been efforts of late to arrange something like that. But there are other approaches to the problem. I'll go a bit further in tomorrow's entry.

Cancer Breakthrough

Hopeful news in recent days about an old and dear desideratum: a cure for cancer. Or at least for a cancer, and a nasty one at that.

The news comes about because investors in GlaxoSmithKline are greedy for profits, and has already inspired a bit of deregulation to boot. 

The FDA has paved the road for a speedy review of a new BCMA drug for multiple myeloma, essentially cancer of the bone marrow. This means that the US govt has removed some of the hurdles that would otherwise (by decision of the same govt) face a company trying to proceed with these trials expeditiously. 

This has been done because the Phase I clinical trial results have been very promising. The report I've seen indicates that details of these results will be shared with the world on Dec. 11 at the annual meeting of the American Society of Hematology. 

The European Medicines Agency has also given priority treatment to the drug in question. 

GSK's website identifies the drug at issue as "GSK2857916," althou…

A Story About Coleridge

This is a quote from a memoir by Dorothy Wordsworth, reflecting on a trip she took with two famous poets, her brother, William Wordsworth, and their similarly gifted companion, Samuel Taylor Coleridge.

We sat upon a bench, placed for the sake of one of these views, whence we looked down upon the waterfall, and over the open country ... A lady and gentleman, more expeditious tourists than ourselves, came to the spot; they left us at the seat, and we found them again at another station above the Falls. Coleridge, who is always good-natured enough to enter into conversation with anybody whom he meets in his way, began to talk with the gentleman, who observed that it was a majestic waterfall. Coleridge was delighted with the accuracy of the epithet, particularly as he had been settling in his own mind the precise meaning of the words grand, majestic, sublime, etc., and had discussed the subject with William at some length the day before. “Yes, sir,” says Coleridge, “it is a majestic wate…

Hume's Cutlery

David Hume is renowned for two pieces of cutlery, the guillotine and the fork.

Hume's guillotine is the sharp cut he makes between "is" statements and "ought" statements, to make the point that the former never ground the latter.

His "fork" is the division between what later came to be called "analytic" and "synthetic" statements, with the ominous observation that any books containing statements that cannot be assigned to one or the other prong should be burnt.

Actually, I should acknowledge that there is some dispute as to how well or poorly the dichotomy Hume outlines really maps onto the analytic/synthetic dichotomy. Some writers maintain that Hume meant something quite different and has been hijacked. Personally, I've never seen the alleged difference however hard they've worked to point it out to me.

The guillotine makes for a more dramatic graphic than a mere fork, hence the bit of clip art above.

I'm curious whe…
