The history of air: Nick Gillespie on Joseph Priestley

January 13, 2009

Lynne Kiesling

Nick Gillespie’s review in Reason makes me even more eager to read Steven Johnson’s new book, The Invention of Air: A Story of Science, Faith, Revolution, and the Birth of America. The main protagonist of this work is Joseph Priestley, one of the foundational chemists of the late 18th and early 19th centuries:

Along with his contemporaries Antoine Lavoisier and Carl Wilhem Scheele, Priestly isolated oxygen gas and was the first to draw connections between “pure air” and blood. However, as Johnson notes, Priestley was trapped within a rapidly failing scientific paradigm, phlogiston theory, which limited his ability to fully understand and accept what he was witnessing in his own experiments. One of the great dead ends in scientific discourse, phlogiston theory was a fanciful and massively influential attempt created in the 16th and 17th centuries to explain combustion, rust, and other forms of oxidation by replacing the ancient Greek elements (fire, water, air, and earth) with a series of previously undiscovered substances. Ironically, Lavoisier would ultimately use Priestley’s own experiments as the basis for refuting phlogiston theory and creating what we now know as chemistry. Like a laboratory Moses, Priestly pointed the way for others to a destination at which he could not quite arrive.

If you are interested in this book, chances are that you will also like Uglow’s The Lunar Men, a book that I enjoyed thoroughly and wrote about here and here back in 2003. Priestley figures prominently in that group in England, along with James Watt, Matthew Boulton, Josiah Wedgwood and Erasmus Darwin, before moving to the US.

Nick’s review of Johnson’s book is quite compelling, and highlights Johnson’s characterization of Priestley as a man “who survived riots, threats of prosecution, and other hardships and yet never doubted that ‘the world was headed naturally toward an increase in liberty and understanding.’” His intellectual curiosity and his quest for knowledge, and the connection between liberty and understanding, are important relationships to bear in mind today as much as they were two centuries ago.

What fixed vs. flexible retail power rates in Texas tell us about wind power in the ERCOT market

January 13, 2009

Michael Giberson

Electric power consumers in (the ERCOT portion of) Texas have many choices when it comes to the electric power retailer they wish to enroll with, and typically each retailer offers a handful of different plans.  Historically speaking, this is a crazy cornucopia of consumer choice not seen anywhere else in the world. Or, seen from another point of view, a lot of data for economists interested in retail electric power not available anywhere else. This post dissects a few bits of that data and offers a preliminary conclusion.

One choice available to many Texas power consumers, but rare elsewhere, is between rates that are variable from month-to-month and rates that are fixed for a longer term.  Typical terms for fixed rate offers are six months and one year, but terms as long as five years are offered.

The primary difference between a variable rate and a fixed rate is whether the customer or the retailer is exposed to the risk of adverse price movements.  A little simple economics leads one to expect that if the retailer is to take on the risk of adverse price movements, the customer will have to pay the retailer to take on the risk. So we’d expect that fixed rate contracts would tend to be higher than variable rate contracts.

And that is just what we see in the offers listed at www.powertochoose.com, the State’s online list (just comparing average offered fixed rate deals to average offered variable rate deals). For example, in the Houston area the average rate for fixed price offers was 14.04 cents/kwh and the average rate for variable price offers was 13.60.  In Dallas, fixed price offers averaged 13.35 cents/kwh and variable price offers averaged 13.03.

But elsewhere in north Texas, specifically the AEP North Texas distribution service territory, the average rate for fixed price offers was 12.7 cents/kwh and the average rate for variable prices offers was 12.8 cents/kwh. So, apparently in parts of north Texas, electric retailers in effect are willing to pay consumers a little bit in exchange for taking on price risk.

Crazy, right?

Well, not exactly.  A fixed rate offer transfers the exposure to both adverse and beneficial price movements.  If a retailer expects prices to fall (relative to the current market expectations), then it would want to encourage customers to lock in at current rates; if the risk of a price movement down is larger than the risk of a price movement up, and retailers are less risk-averse than individual consumers, then retailers would be willing to pay consumers to take on the risk.

And why might retailers in certain parts of north Texas expect prices to fall? Might it be access to large quantities of wind power that sometimes can’t reach Dallas or Houston due to transmission limits – sometimes such large amounts of wind that prices in the ERCOT west region go negative?

I think so.

Admittedly, simple averages of offered fixed and variable rates provide only the coarsest of indicators of what is going on. Maybe more sophisticated analysis makes the anomaly disappear. But at first glance, it looks like another market indicator of the temporary excess supply of subsidized wind power in west Texas.

Cass Sunstein, OIRA, and nudging

January 13, 2009

Lynne Kiesling

On Thursday President-elect Obama named law professor Cass Sunstein to head the Office of Information and Regulatory Affairs, an executive-branch office with the mission of analyzing and coordinating federal regulation. Most recently, Sunstein is known for his work with Richard Thaler on “choice architecture” and behavioral public policy, including their book Nudge.

Others have already opined about Sunstein’s appointment, including Saturday’s editorial from the Wall Street Journal and this Forbes column from Glenn Reynolds. Matt Welch helpfully aggregates several commentaries on Sunstein’s appointment in his Reason post. The consensus seems to be that Sunstein’s approach to regulation is not premised upon bureaucratic imposition and control, that his primary focus is to improve markets and competition, not to stifle them through government regulation, and that much of this is likely to be irrelevant because OIRA is a politically impotent office, so his efforts will have little effect.

Most observers will be watching to see what form Sunstein’s focus on “choice architecture” and behavioral public policy will take when and if it gets implemented. The premise of this behavioral approach to what I (and Elinor Ostrom) would call institutional design is Sunstein’s and Thaler’s so-called “libertarian paternalism”. Sunstein and Thaler draw their normative policy implications from behavioral economics research that suggests that real-world decision-making does not always result in individuals making the decisions that theoretical models suggest would be optimal, or rational. In his review of Nudge, Will Wilkinson cites some examples:

If a cafeteria puts its key lime pie a bit out of the way, fewer people will succumb to delicious temptation. If employees are not required to fill out confusing paperwork to enroll in a savings plan, more of them will enroll.

One area where this behavioral issue comes up in electricity instutional design is the design of fixed-price default service contracts, and whether the default contract should be opt-in or opt-out. Those who argue it should be opt-in base their argument on consumer inertia and status quo bias — if the heretofore-regulated incumbent is the default service provider and the default contract is opt-out, innate consumer inertia would predispose them to stay on the default contract, even if competing suppliers could now enter the market and offer services that would likely be appealing to those customers. Thus by reinforcing existing inertia and status quo bias, the opt-out default contract reduces competitive entry into new retail electricity markets, and stifles retail competition. This opt-in/opt-out design dimension is relevant for health care plans, retirement plans, any sort of contractual choice situation with a status quo option.

In some ways this approach is a refreshing change from regulation that is informed by traditional, neoclassical economic modeling of individual choice, which is devoid of any formal attention to the real cognitive constraints that individuals face daily when bombarded with information and making choices in the face of budget constraints, information constraints, and (to use the Austrian phrase for it) radical ignorance — some of what individuals need to know to make the decisions that they would in our formal theoretical models is simply unknowable. Note here that the ideas I am using originate in the work of Herb Simon on bounded rationality and the use of heuristics in individual decision-making, and of Michael Polanyi on tacit knowledge and the extent to which we know stuff that we don’t know we know, and our brains subconsciously make choices constantly, which enables us to function in our information-rich environment without being overwhelmed. This behavioral approach to institutional design takes into account two important aspects of reality:

1. Individuals do face cognitive limitations on their decision-making, and have evolved adaptation mechanisms to deal with them.

2. To live together in civil society, we do have to engage in collective action, which requires institutional design.

In other words, take people as they really are, and when we have to engage in collective action, design institutions that take into account those cognitive realities. Yes. But here’s where my skepticism about the Sunstein-Thaler libertarian paternalism kicks in. Much of what is important in public policy is shaping incentives and future behavior. If we take Simon and Polanyi, and Hayek, seriously, then it’s crucial to acknowledge that a lot of what shapes incentives and future behavior is not just unknown — it’s unknowable. We don’t know our own preferences completely — we discover them through market processes, and through the process of making decisions. We don’t know what future choice sets will look like, let alone what our preferences over those choices will be. These things are simply unknowable, and therefore designing institutions to affect those unknowable incentives and outcomes is almost always likely to end up in failure. This approach to choice architecture cannot overcome the knowledge problem. So I think the best that we can hope for from such a so-called “libertarian paternalism” approach to regulation is small, local changes in design parameters that are well-known and relatively non-controversial.

Another aspect of the challenge to this approach to institutional design is indeed the elitist-paternalist critique: how will the regulator know in every situation that Choice B actually would make the individual better off than Choice A? What makes you think that you know what is better for me than I do? Seriously? Again, the unknowability of preferences until presented with a real choice situation, even to the person possessing them, makes it highly unlikely that any third party can know that one outcome would be better for a person than another outcome. This is old territory that has been covered elsewhere, including this April post from Will Wilkinson, so I will stop here, except for one observation: just because we face cognitive limitations to decision-making, that does not necessarily mean that the ultimate outcomes of decision-making are inefficient, or irrational, or “anomalies”, to use one of Thaler’s favorite linguistic tropes. Again, taking Simon and Polanyi and Hayek seriously, we devise conscious and subconscious adaptations to these cognitive realities, we use technology to help us filter and to make decisions that better reflect our preferences as we perceive them. Who are you to say that the outcome of that process is irrational or inferior?

Another question to ask when thinking about the process of institutional design and behavioral economics: why would these “Nudge” rules be any less prone to political manipulation, lobbying, and rent-seeking than more traditional top-down institutional design? The electricity default contract is an example; the traditional “consumer advocate” community generally uses its political and advocacy power to argue that opt-in default would expose consumers to too much unwanted price volatility and too much effort to avoid that price volatility, so the default should be everyone going on a fixed-price contract unless they want something else. “Nudge”-based institutions are still institutions of collective action, and thus are still going to have the same incentives for manipulation, lobbying, and rent seeking.

Finally, while I do think that the process of institutional design, including regulatory institutional design, can benefit from thinking about these choice architecture questions, I do think the “libertarian paternalism” nomenclature does a disservice to the language. “Nudge” applied to regulatory policy is not strictly libertarian, because regulation is still ultimately grounded in coercion. The “choice architecture” language does a much better job of communicating what this idea is about — incorporating behavioral and cognitive reality into institutional design. At least the “Nudge” approach to regulatory policy is more respectful of individual autonomy and choice than the likely bureaucratic alternatives.

In devising OIRA policy I’d like to hear Sunstein invoke another of his former Chicago colleagues, Ronald Coase, and state that in promoting and facilitating open, transparent markets, the most important role of economic regulatory policy is to reduce the transaction costs that prevent private parties from engaging in mutually-beneficial exchange. That means using OIRA to evaluate the entry barriers and other transaction costs that federal regulation can create. OIRA does cover other areas of regulatory policy where the ideas of transaction costs are not as strictly relevant, but thinking in terms of reciprocal benefit, reducing transaction costs, and the alignment of, for example, environmental and economic incentives through the reduction of transaction costs and better-defined property rights transcends economic regulation.
