The Time Value of Information and Material Wealth

Conventional economics says money today is worth more than money in the future.  This is why people are willing to agree to pay interest on a loan (and why a creditor requires it).  How much more money is worth today than in the future is determined by the discount or interest rate (depending on what kind of calculation you’re doing).  This would hold true, say the economists, even if we lived in a hard money world (e.g. silver and gold), and even after accounting for the risk of default by the debtor, because of opportunity costs.  Creditors and investors presumably have a choice as to what they do with their money.  Sitting on your pile of treasure in a vault ensures that it doesn’t get smaller, but it also doesn’t get bigger.  When they choose to make a loan or invest in an enterprise, they are, it is assumed, seeking the best possible (risk adjusted) return, and so the value of a given present pile of money at some time in the future is the principal invested plus the return earned between now and then.  If you can make 10% per year on some investment, and you have $100, and someone offers to give you $105 a year from now in exchange for your $100 now, all else being equal, you refuse, invest at 10%, and end up with $110 next year instead.

This conception of money is somewhat problematic, as it tends to render everything in the time and world of your grandchildren essentially worthless in the present.  Even at a modest 5% discount rate, $100 a century from now is only worth $0.59 today.  I think the problem comes largely from the convolution of informational and material wealth, and our habit of representing both of them with the same currency.

Confessions of an Economic Hit Man by John Perkins

I just finished reading Confessions of an Economic Hit Man by John Perkins.  It’s his personal account of working as an economic forecaster for an international infrastructure engineering and consulting company called Chas. T. Main during the 1970s (it’s since been purchased by Pasadena’s very own Parsons).  If I remember correctly, I got this book from Arjun.

It was widely criticized when it came out as being the rantings of a conspiracy theorist, and I think that by the end of the book, it definitely takes on that tone.  This is unfortunate, because a lot of the problems that Perkins points out really do exist, and it actually doesn’t matter much whether they’re the result of a shadowy global conspiracy, or a structural problem with our international economic and development system.  But most good conspiracy theories contain a grain of truth, and at the very least they can provide a useful lens into how the same situation and facts can be interpreted differently by people in different positions, with different experiences, and different incentives.  In that light, the book is asking the reader to consider what debt-based foreign development aid looks like from the point of view of the poor people living in the countries receiving the aid.  This is actually a really interesting thing to think about right now, because our current financial and economic crisis has been described by some as similar in many ways to the kinds of crises which the IMF and World Bank have historically been called on to deal with in “developing” economies.

  • A New Way Forward – Grassroots banking policy? Who'd have guessed? Their plan is "Nationalize. Reorganize. Decentralize." The N-word has some bad connotations, but what they're really advocating for is an FDIC style managed bankruptcy, i.e. letting the banks fail, cleaning out the shareholders and management, and applying real anti-trust laws to the financial industry. I never thought I'd go to a banking protest. (tagged: economics bailout finance fdic activism banking policy )
  • MailStopper – Is $20/year too much to pay to avoid junk mail? Would it really work? The self-monitoring aspect is interesting too. Would be great to be able to watch your name and address as it propagates through the ocean of direct marketing databases, and credit reporting agencies. (tagged: green junkmail sustainability internet )
  • YellowPagesGoesGreen.Org – I hate the two kilograms of cellulose that the phone company insists on littering my doorstep with each year. I was a little bit drunk when they showed up last week, and threw them in the street. I don't even have a land line. Why would I want a phone book? Who uses those things anyway? Thankfully, someone else has already created an opt-out system… too bad I'll have to wait a year to see if it actually works.

  • The Age of Stupid – A new combination sci-fi documentary on climate change… framed as a man looking back and trying to understand why we failed to act, from the year 2055. The movie was "crowd funded" – the filmmakers sold shares of the profits to individuals (and the crew) in exchange for cash (about $1 million total). The trailer looks fairly good… (tagged: climate film green environment )
  • Mistrial by iPhone – Juries’ Web Research Upends Trials – Another example (cf death of record companies, newspapers) of technology upending previously stable social and legal systems. 9/12 jury members found to be doing research on the trial they were sitting on, via their cell phones and the internet. People don't consider the meta-brain to be a separate entity any more. Certainly not for weeks of sequestration on end… (tagged: law technology internet phone jury trial )

Have you seen the light?

As animals, and especially visual animals at that, we have a particular experience of the light.  For us it is illumination, information about our surroundings.  For that purpose moonlight or even starlight will do.  And for tens of millions of years, that’s all we ever saw.  Somehow a few of us made it through the Permian extinction, and into the Triassic, but the ascendancy of the dinosaurs eventually forced us into the darkness of the night.  Our world became dim, and our eyes went colorblind.  Most mammals today see only two colors, but a few of us have re-evolved a third photoreceptor.  Three colors is still inferior to the four or five or six seen by many near-surface fish, birds, reptiles, insects, and other arthropods.  The stomatopods are almost biological spectroscopic imaging systems, with 12 color channels in each of their independently movable trinocular eyes.  We are lesser than the eyes that never left the light.  They stole the colors from us and made us hide within the night.  They kept the sun for themselves, not knowing that our small and furtive ways, our burning endothermy and our fur would see us through the aftermath of the KT impact.

The Evolution of Cooperation by Robert Axelrod

The Evolution of Cooperation was, somewhat surprisingly, a story about math. Math that actually describes a lot of things in life. It’s the story of The Prisoner’s Dilemma.  What makes The Prisoner’s Dilemma interesting, is that the players in the game have conflicting incentives.  You can be rewarded either for cooperating, or for defecting.  Unlike most things we think of as “games”, it is not zero-sum: both players can win, and both players can lose.  Too often it seems like this possibility is forgotten.  The dilemma goes like this.

Two suspected accomplices are taken into custody for a crime and separately interrogated.  Each is pressured to rat out the other.  If neither of them squeals (they cooperate) then both of them get short jail terms.  If both of them rat, they both get fairly long terms.  If only one of them gives in, and the other remains silent, then the fink gets off, and the honorable thief goes away for a long long time.

  • The Missing $1,000,000 Tax Bracket – There's a fair amount of debate over what the "top marginal tax rate" should be, but it's infrequently noted that there's actually vastly more variation in the income threshold at which that rate becomes applicable. In inflation adjusted dollars, it's fluctuated between around $80,000 (Regan) and $80,000,000 (!) during the Depression. Ignoring this while debating the highest income tax rate is kind of absurd.

  • Evangelical Climate Initiative – A Christian take on climate change, given its reality, what is the appropriate response for a conscientious person of faith? From my point of view as an atheist, it's not so important what other peoples' motivations are for taking action, as long as they take action. I'm curious how this has been received by the evangelical movement. (tagged: religion climate science christian green )
  • Sailfish Cooperating to Hunt Sardines – I had no idea sailfish were so colorful (and changeable), let alone this cooperative. Glad National Geographic still exists, even if our maps no longer have "Terra Incognita" on them (tagged: fish cooperation nature )
  • Communicating the Second Premise: Whether Obama or Bush, Values Drive Science Policy Decisions – A good look at the division between science facts/findings and science policy in the context of stem cell research and Bush's vs. Obama's take on it. Facts alone do not imply any "shoulds". We need values to tell us what's right or wrong. Sometimes those values are so obvious we don't even think about them, and sometimes they're not, especially when new and poorly understood technology is involved.

The holes in my woolens

I discovered a couple of small holes in one of my my merino sweaters this morning.  Moth larvae.  My fault for not using camphor or some other kind of deterrant.  At first, I was bummed because I thought this represented a flaw – I love wool, and especially merino, because it’s warm even when it’s wet, it wicks, it doesn’t smell, it doesn’t burn and melt like plastic, it’s durable and comfortable and not based on petrochemicals.  But moths can eat it, and it can mold.  It requires more care than fleece.  Thinking just a little more, it occurred to me that actually, these holes are in some sense a feature, not a bug.
