Big data helps monopolies, not you

Economists say competition in markets rages from “perfect” (no company can charge a price over cost without losing 100% of its customers to another company) to “monopoly” (one company sets prices to maximize profits).

Two caveats are important. First, the monopolist doesn’t charge as much as possible but whatever maximizes profits. There might be a lot of trading going on, but also a lot of missing trades. Second, businesses seek monopoly power in different ways, from having a unique product with zero substitutes (pretty rare) to being open for business at a certain time and place (pretty common). Businesses often try to create monopoly power by making it hard to compare products with competitors or across boundaries. That’s why they sell the same razor in pink for women and blue for men, change model numbers for the same product in different markets, change package sizes, and so on.

Thus, businesses make it harder to see similarities and differences because confusion for you means larger profits for them.

Flipping this idea over, businesses want to identify similarities and differences among customers to make it easier to charge different prices to different customers. Their goal is not to charge as much as the market will bear but as much as you will bear.

Thus, businesses “price discriminate” (PD) in a quest to get $4 from you and $6 from me for the same product.  There are three types of PD, arranged from easiest to hardest to implement:

  • “Third degree PD means charging a different price to different consumer groups,” e.g., young vs old or lunch vs dinner.
  • “Second-degree PD means pricing according to quantity demanded, e.g., larger quantities are available at a lower unit price.”
  • “First degree PD means (FDPD) charging the maximum price each consumer is willing to pay.”

There are many examples of second and third degree PD, but FDPD is harder to pursue. In the past, we got close to FDPD with auctions in which the highest bidder won the good, but auctions take time and still leave money on the table (the winner only needs to outbid the second place bidder).

Now the technology exists to allow routine and widespread FDPD. That technology has arrived with “big data,” and it’s not your friend.

Why?

  • Our social media habits reveal our likes, choices, and friends
  • Our social graph links us to friends and relatives, allowing data to be cross-checked and refined with weak or strong links to the people around us.
  • Our loyalty cards, credit cards, and credit scores can be used to understand our ability- and willingness-to-pay
  • Our phones track everywhere we go.
  • Personal fitness devices record our heart-rates, stepping speed, etc.
  • Data brokers can cheaply buy and combine many datasets and use machine learning (AIs) to create our “digital twins.” Twins may not be too accurate when they are born (here’s one effort), but your actions are constantly being compared to your twin’s predicted action. With time, your twin will will know you better than you do.

Taken together, Big Data means that you will be paying more and getting less for many goods and services. At its most-dystopian extreme, Big Data will direct you to friends, work and romance based on business profit-maximization instead of your own ideals of happiness.

My one-handed conclusion is that big data is more of a curse than a blessing for the average human.


NB: I’ve blogged for years on the weaknesses and threats of social media, but this post also draws on my 25 years of experience in working with data and the many ways we abuse data.

Some people getting uppity

The title of this post refers to how some whites refer to successful blacks in the US. (They also bomb, lynch and imprison those blacks.) The gendered-version of this slander is “putting women in their place.” When it comes to the poor, the rich say they should “pull themselves up by their bootstraps.” The young? Some oldies complain about “kids these days.”

In all of these cases, the better-off complainer ignores their social and historical privilege. They rarely consider how the economic, social, political institutions created by their ancestors have put them firmly at the top end of a tilted playing field.

So the relative improvement in the lives of racial/ethnic minorities, women, the poor, and the young upset the privileged, the most prominent group of which is composed of old white rich men, who I’ll label “Donnies.”

The Donnies don’t like uppity people invading their world, so they lash out.

“Ethnics” invade Donny pools, restaurants, and professions. Even worse, they marry their women and move to their neighborhoods.

Women are doing better in school (now that they can attend), taking Donny jobs, making more money than Donny, and even (!) deciding they don’t need to trade their womb for Donny’s money. Donnies are mad, so they accuse women of having sex or being ugly — as if that will fix Donny’s bad grades, low earnings or lack of sex appeal.

Donnies hate it when the poor succeed, calling them “nouveaux riches.” Many Donnies owe their wealth to colonial pillage, family, or social networks that allow stupid Donnies to collect outrageous salaries (I went to school with many of them). Donnies caught lying and stealing don’t often face punishment, but the poor do [pdf].

The young? Donnies tell them to respect their elders when all there is to respect is wrinkles and hair loss. In the distant past, respect made sense, but old people today probably owe their longevity to medical science, welfare systems and professional carers.

A few years ago, Barack Obama was castigated for saying that business owners “didn’t build that” without outside help. Although business owners work hard, Obama was right to call attention to the enabling environment that made their success possible. Many Donnies take those institutions for granted. Others (like the Criminal-in-Chief) take advantage of the system. In my experience, I’d say that about 80 percent of these Donnies would break down in tears if they faced the business-climate of China, Mexico or Thailand. They wouldn’t even last a day in Argentina, Egypt or India.

My one-handed conclusion: The Donnies of this world are getting upset as they realize how Others are earning the success they never did.

Innovative bureaucrats?

The Dutch are fond of subsidies for arts, sustainability and… innovation.

These subsidies arise when bureaucrats with “topical portfolios” award cash to winners of various “promise to stimulate [topic]” contests.

On the one hand, I am pleased to see the government providing public goods, i.e., stimulating efforts to help everyone.

On the other hand, these programs tend to find the least-productive incentives to advance the “topic”

(My one-handed view is that this structure is wrong… keep reading…)

So the irony is that the bureaucracy in charge of innovation…

  • …has permanent employment contracts and long vacations;
  • …gains nothing from success but loses nothing from failure;
  • …works in non-market areas where the lack of objective measures of performance leads to subjective choices of winners and losers; and
  • …happily spews a meaningless whirlpool of jargon borrowed from strategic plans, conference videos, and social media #buzzwords.

If I was in charge of these topics, I would follow the new development model of “pay for results” by specifying the criteria for success and then rewarding the most successful efforts to reach those goals with cash and publicity.

This system would have nothing to say about who did the work, what angle they took, or how fancy their method. It would pay for results. 

My one-handed conclusion is that governments should stop chasing “creative,” “innovative,” “smart,” or “sustainable” and just reward results. 

What’s your experience on this topic?

World War CC

I’ve been alarmed about climate change chaos (CC) since 2016 (before that, I thought it was a distant, negligible threat to me), and I’ve been evolving my perspective on what it means to us.

My first conclusion was that mitigation had failed. So I turned my attention to adaptation, which was easy because it means dealing with a more aggressive water (and thus heat, storms, floods, etc.) cycle. 

In my first vision, I thought of a zombie apocalypse, of great waves flooding unprepared cities, Zero-day events everywhere, etc. I don’t think that any more because I see CC as a series of small cuts that draw a drop of blood per occurrence but, taken together, bleed you out.

Slightly off-topic, but Richard Tol is an idiot if he doesn’t understand that different places with different climates are not interchangable (10K = 10C). Ask a tree, for example.

But what does it mean to suffer these cuts? Can’t we ignore them, as we get richer and thus able to afford the costs of CC? Unlike William Nordhaus or Richard Tol (right), I think not. Indeed, I think that these cuts will resemble World War II in their impact on our lives, but be worse due to their never-ending nature that will build, exponentially, until our descendants curse our blind stupidity.

So what would a perpetual WWII (WWCC) look like?

First, there will be a permanent decline in our standard of living. We will have shortages, disruptions, additional costs, and spend way more time worrying about what we’re missing, what we “really need,” and if things will be better in the future — or not. (One woman is giving up a lifetime of buying new fashion for second-hand clothes.)

Second, the future of “growth/development” will not be hopeful. Our  productive assets will be destroyed. The resources directed to defense and recovery will leave less for production. People will not choose jobs for ideals, prestige or salary, but because those jobs still exist, are protected in some way, or must be done.

Third, everyone will experience a different type of WWCC. Politics, violence, alliances, and migration will vary from place to place, with laws, nationalism, (failing) institutions, and so on. My advice is to make sure you have all your paperwork in order. Many Jews (including Anne Frank) died because they couldn’t get visas to escape the Nazis. Don’t forget the horrors of recent civil wars in Rwanda or Yugoslavia, where close neighbors (and sometimes relations) turned genocidal. Many politicians will make matters worse.

Finally, WWCC, like the war on poverty or war on drugs, will never end. That fact will make it hard to “plan for the future” and depress a lot of people. It will also undermine business investment, innovation, and the dynamism of markets that originates in our basic optimism and tendency to trust. Human society will experience dark ages not seen since the Black Death, colonization, the Little Ice Age, etc. People will die in mysterious ways, strange goings on will surprise people, witches and healers will promise redemption to those who can cross their palms with silver.

My one handed conclusion is that humans will definitely survive in a climate chaos future, but sometimes wonder if it would be better to be dead.

Addendum (19 Oct): “Ultimately, capitalism is going to lose its customers. There won’t be anybody to buy the product because everybody is going to be so poor.

Libraries and revolutions

I was thinking of doing two posts (one each on libraries and revolutions), but I think I found a reasonable way to combine them.

First, revolutions.

Some claim that low union membership in the US is a sign that unions are no longer valued by workers. I think something the opposite, i.e., that unions did such a good job that they were taken for granted by middle-class workers who felt their quality of life was secure from the depredations of “capital” and other “class enemies.” Today, few union jobs remain as a combination of declining membership and right to work laws have undermined the coordinated collective action necessary for unions to represent a countervailing force against employers.

The post-WWII decline in unions has been accompanied by increasing inequality in many countries — an increase that took off under the influence of Thatcher/Reagan reforms in the 1980s and has resulted in the crisis of inequality highlighted by Piketty, Occupy Wall Street and the Tea Party. (Trump has used a version of events to justify his moronic and self-serving agenda. His actions have worsened conditions, as I’ll explain when we get to libraries below…)

These post-WWII inequality dynamics got me to thinking of two ideas: First, revolutions up-end the old order, resulting in short term losses but then medium-term prosperity. In the long run, however, the rich/powerful/elite tend to centralize their control and direct income and wealth to themselves.

Thus, the agricultural revolution occurred ±10,000 years ago, replacing semi-egalitarian hunter-gatherer societies with settled communities. In the “short-run” of the first 4,000 years (!), this system was bad for the individual but good for the group (read my reviews of Sapiens and The Secret to Our Success). After that long adjustment, however, agriculture fed an explosion of human flourishing in which the average person was better off and communities were reasonably egalitarian, at least compared to the late middle ages, when the rich and royal owned most of the land and many slaves as they grew fabulously wealthy. 

The end of this age is often linked to the French Revolution (1789) but the Industrial Revolution also played a part in overturning power relations and opening up an entirely new set of possibilities based on a different model of production. 

The industrial revolution followed a similar pattern of painful disruption, growing benefits to the working classes, and a resumption of control over income and wealth by the rich and powerful, this time at about 50 times the speed (i.e., “bad times” for 80 years rather than 4,000 years). The beginning was terrible for workers (thus the rebellion of the Luddites), but matters improved as workers unionized, slaves were freed, and the benefits of mechanized agriculture and manufacturing went to the working classes. Industrialization brought globalization (the telegraph, steam ships, migration) but also total war, as seen in the millions of victims in the two world wars. After the Great Depression and WWII, there was a firm improvement in living conditions (from a very low base) that benefitted the “average Joe” between 1950 and 1980. (These benefits didn’t go to poorer countries, some of which were lucky to escape colonial rule.)

The 1980s is seen by many as a turning point of inequality, which I’ll agree to. Yes, there was more freedom for “individuals,” but there was also a massive swing of wealth, from the majority to job creators, masters of the universe, and global tax dodgers.

The information revolution began in the 1960s, but it really took off in the 1990s, as the Internet matured and spread, driven ahead by Moore’s Law and an emerging economics of “winner takes all” platforms and economies of scale. In this scenario, short-term disruption and middle-class gains took only a decade to process before the elites were again collecting the majority of gains. Yes, Facebook is free. Yes, many people spend hours being “entertained” by their feeds. But most of this activity is a distraction from the massive concentration of income and wealth in tech companies based in the US and China (except when it comes to taxes). I’ve complained before about the negative impacts of tech — and its loss of innocence — so I’ll just leave it there.

My one-handed perspective is that revolutions are temporarily disruptive, until the elites find a way to regain control and enrich themselves at the expense of the rest of society.

So how does this relate to libraries?

A few months ago, my girlfriend was telling me that her old hometown in Romania did not have a library, as there was “not enough money” to support such an institution.

I went on a rant about how a library is probably more important than a school, as a library provides a public, free meeting space for people to study, talk and cooperate in tackling problems, planning their future or doing their homework. These “public good” services help allow anyone in the community to benefit without payment, unlike private clubs, most schools or cafes. Those benefits are probably radically higher than the cost of libraries to taxpayers, which means that they should be set up as soon as possible in new communities and protected for as long as possible in the face of tight finances. (Read this, this or most anything here.)

Try telling that to Trump voters. In this NYT article, the author visits an Arkansas community that supports Trump but doesn’t see the point of a library — or paying taxes. Instead, they seem to think it’s better for folks to “take care of their own” without funding or support from the government. I see their “go it alone” attitude as the product of a mix of bravery, naiveté and ignorance: They beleive they don’t need help, assume they can survive everything from medical emergencies to natural disasters with their own resources, and believe that taxes and spending represent a zero-sum game. This last point is perhaps the most damaging, as it denies the main reason that we have governments: the provision of public goods that cost some money to provide but provide much greater benefits to people. More importantly, public goods (like the library but also security, information, clean air, etc.) are pro-poor because they are free to users. (This article makes that point indirectly, as students care more about the basics — quiet space, wifi — than the fancy bells and whistles that tech consultants sell to trend-chasing bureaucrats.)

Thus, we arrive at a terrible paradox: Inequality is rising as the information revolution rewards elites but the poor are turning against means of helping themselves (libraries, Obamacare, etc.) due to their mistaken belief that Trump and Republicans — their tribe — cares about them. They don’t.

My one-handed conclusion is that America’s less fortunate are only going to be worse off as the rich and Republicans conspire against them. What happens next? Either they will eat cake or start another revolution — and it won’t be pretty.

 

Participatory budgeting in Amsterdam

I live in the West district in Amsterdam, where the local council has given residents power to allocate €300,000 to projects proposed by anyone.

I welcome this participatory process, but it has some flaws, which I’ll discuss here, along with my recommendations for improvement.

First, let’s clarify that this process is heavily managed. The amount to allocate is a tiny fraction of the total budget for the district, and experts make sure that proposals from the community are “feasible.” 

Even still, the voting process is flawed. Last year, I was surprised to see that I was asked to allocate the total budget of €300,000 among proposed projects. This process gave far too much weight to big projects, since projects were selected based on the number of votes they got from residents.

For example:
1st place: €50.000 project chosen via 12,839 votes = €4.03/vote
2e place: €5.000 project via 12,367 votes = €0.40/vote

As you can see, the way to win is to have a big budget, which will crowd out other projects (by absorbing the vote budget) as well as benefitting from voter fatigue, since it’s easier to choose one €50k project than choose ten €5k projects. (I’m pretty sure city bureaucrats also prefer to administer one big project over ten smaller projects, since per project set up costs are probably similar.)

Luckily, there’s an easy solution: give voters a “personal budget” of, say, €300, and then let them put 0-100 percent of that onto as many projects as they can afford. 

Thus, I can vote €150 to project 1 (€50.000, meaning its now 0.30% closer to happenings) and €150 to project 2 (a €5.000 project that’s now 3.0% to funded).

My one-handed conclusion is that voters will get better value for their taxes if they vote a personal budget. 

Addendum (19 Oct): The local bureaucrats in charge of this initiative clarified that this process will allocate 21% of the budget (good!) but they like their current method (sad!).

Climate chaos is like Brexit

I wrote the headline for this post before I decided to add more content (below), but it’s good to start off with the Brexit parallels.

Climate chaos, like Brexit, combines uncertainty, missing leadership, and wild promises into a realistic scenario of enduring disaster and regret.

But climate chaos is also not like Brexit, which some interpret as a game of “chicken” between the EU and BoJo, each trying to force the other side to swerve (to avoid a messy crash) and thus win. Although BoJo is doing a terrible job, the climate chaos game is more like a game of Bambi Vs. Godzilla in which humans (Bambi) don’t do so well.

If you’ve taken the 20 seconds to make it this far, then here’s the next bit:

Climate chaos will make us poorer and undermine our futures. 

We will be poorer because we will need to spend more and more of our income and wealth in defending ourselves against the massive forces of Earth’s climate systems.


I’ve had a number of guests on my podcast discussing various dimensions of climate chaos. Here’s the playlist, but I recommend you listen to the most recent episode with Femke Gunneweg, a 19-year old who’s suspended her studies to join Extinction Rebellion. Our chat was quite interesting.


Have you heard of Imelda? It was a tropical cyclone that dropped 40 inches (about 1 meter) of rain on the greater Houston area last week. Perhaps you heard of Dorian? That Cat-5 hurricane tied in first place for the strongest Atlantic hurricane ever recorded, with winds of 285 kph and a storm surge of 8 meters. The US was lucky to miss most of Dorian, but the Bahamas was hit hard, with over 1,000 people presumed dead. The hurricane season has just begun.

Our futures will be up in the air because “only a few degrees” can topple governments, undermine accepted wisdom, and reorder social norms

What’s to be done? Here’s a quick primer:

Climate chaos drivers

The Industrial Revolution was driven by coal and later oil power. These fossil fuels allowed us to multiply our wealth by burning the condensed energy of millions of years of sunlight and photosynthesis, in a decidedly non-renewable way.

As a result, we’ve had an explosion in population, from roughly 1 billion in 1800 to 7.7 billion today. These people are also wealthier, on average, than all previous humans, which means that each person’s “footprint” is bigger and more damaging. Technology has helped us do “more with less,” but there’s no sign of reducing the rate of fossil fuel consumption (and thus GHG emissions). Record and increasing deforestation reduces the absorption of GHGs, besides bringing many other problems.

Note the irony that it’s the middle class that is the main driver of climate chaos. The rich consume way too much, but they are too few. The poor just try to stay alive (sometimes causing environmental problems), but the middle class, with their desire to spend their disposable income on more,  cheaper stuff that’s really driving this process. Marx would be annoyed.

Climate chaos facts

1. Mitigation (reducing fossil fuel consumption) is failing due to greed, political distractions, and weak global mechanisms for collective action.

2. Many politicians accept this status quo because elections today are more important than survival tomorrow (ask Bahamians).

Take Germany, for example. Most of you know about Germany’s solar panels and wind farms, but did you know that its energy transition has cost nearly $1 Trillion, that the Germans are shutting down safe functional nuclear plants (due to an accident in Japan), and that Germany’s renewable energy production, despite reaching around 20-30 percent of the total, is still in the bottom half of EU nations? I’d say that this slow progress (contrary to press releases) reflects domestic political priorities, such as the those of the German car industry. And Germany is one of the good guys. Australia, Canada, and the US are shameful laggards.

3. Scientists have been very conservative in building their models, interpreting data, and projecting future harms. This conservatism (taken to its limit at the IPCC, where nothing is published without a consensus of all contributing nations) means that the news is always worse than we expect, since projections are based on best case, rather than average scenarios. The Paris Agreement, for example, requires “yet-to-be-invented” technologies to suck GHGs from the atmosphere to even meet Nationally Determined (voluntary) targets. Where’s the Manhattan Project or Apollo Project when you need it?

4. The denial industry has been very successful at scaring politicians and driving scientists into further timidity. Oil and gas companies have millions to spend on lobbying. Most humans are busy with life, but others have decided that “climate” is a political concept rather than a scientific fact. Their belief will not keep them from drowning, burning, starving or whatever element of climate chaos kills them. Economists — with William Nordhaus at the top of the list — deserve some blame here. 

5. All of these impacts were predicted decades ago, but scientists made the mistake of talking about rises of 2C and impacts in 2100, which led many to the unfortunate conclusion that impacts would occur after they were dead — and who doesn’t like a little more warmth, anyways? As it is, the hippie doomsayers of Population Bomb, Small is Beautiful, and Limits to Growth were right, just around the time I was born. But not enough people listened 🙁

Climate chaos dangers

We’re already seeing higher sea levels, record temperatures, powerful storms, and bigger fires in unexpected places. People will die in “accidents” at a greater rate.

Chaos means uncertainty instead of risk, so insurance companies will withdraw from the market, leaving people to face 100% of their losses.

Tipping points are coming fast. The Arctic is warming at alarming rates. Icesheets in Greenland and the Antarctic are sliding, rather than melting, into the sea. Massive forest fires are adding to warming by releasing more stored carbon. Fifty percent of corals are dead. This sad list is getting longer.

Humans are barely prepared. We’ve depleted groundwater that we’re want  when drought hits. We’ve built in flood zones that will soon be underwater. We’re more excited about electric cars, reusable bottles, and banning plastic bags than cutting air travel and meat consumption by 80%. People are more worried about “decluttering” their excesses than losing their lives to the results of over-consumption.

We need to act. By diverting resources from vacations to fortifications. By building political alliances rather than attacking others who also like living. By giving the youngest people among us hope for a decent future rather than “fuck you, I got mine.”

My one-handed conclusion is that we’re on a Highway to Hell, and it’s going to take a rebellion to stop this emergency. What are you doing?

Economics, capitalism and social progress

HH, one of my LUC students, wrote the following comment in the discussion board for my course Social and Business Entrepreneurship. I think it’s worth reading:

I think there is one area which is going backward – ‘Democracy.’ Due to tech advancement, now we can access information easily, but it is hard to verify whether it is reliable or not. Just like we had seen the American Presidential election in 2016, fake news dominated the Internet. On top of that, the same thing happened in the UK, the Brexit referendum. As Huff also mentioned in his article [PDF link], people tend to become less critical if there is too much information. It’s just out of our capacity to process everything with accuracy within a certain amount of time. Thus, people tend to go for an easy choice, believing what they want to believe, rather than evaluate information more thoroughly. Also, echo chamber effect makes it even worse. I think this is another critical challenge we are facing now – fake news on social media and the crisis of democracy. Check out this article, if you are interested in this topic: 

Also, on the discussion about poverty alleviation and progress, I agree with what A___ said: the world is focusing more on growth than achieving equality. But often what I found uncomfortable is a somewhat disparaging view towards profit-seeking companies, especially in the LUC community. I am not sure that I am the only one who felt this way, but from my perspective, money is neutral, and there is nothing wrong with pursuing it. The reason why capitalism is more successful than communism is that it understands the power of motivation and incentives. These are the foundation of innovations that make the world a better place. I believe, if they are not involved in illegal activities, purely profit-seeking firms can contribute to society by increasing productivity, investing in R&D, creating jobs, and so on. In addition, we all benefit from the products and services they sell. Only the way people use money determines the value of the money. I hope that many LUC students in the future become “successful entrepreneurs” and earn a lot of cash “ethically” and become “philanthropists.” I think it is way better than demanding the rich to share what they have. You can be the rich, and use it for the right thing.

To this, I replied:

What worries me is that some LUC’ers (and many people) take the old world view of profit as theft (zero-sum game) when the “magic” of economics is its revelation of win-win dynamics. This was why Smith (1776) was so influential.

Some people mistake economics for capitalism, which it’s not. But, worse, they also misunderstand capitalism as “=evil” when really:

Capitalism is an economic system based on the private ownership of the means of production and their operation for profit.

This definition and discussion doesn’t get to the important role of government, in creating the conditions for capitalism and also regulating its functions (competition, transparency, etc.)

These failures mean that those LUC’ers oppose institutions that create gains from trade and pt capital assets to good use: two main sources of our prosperity.

There are problems with markets (externalities) but there are also many problems with society (poverty) and government (corruption), so let’s keep all these issues in mind when seeking targets.

My one-handed conclusion is that many people blame capitalism for political failures.

An (ig)nobel tragedy

In my most recent newsletter, I wrote:

I was surprised and upset to hear that Marty Weitzman, a Harvard environmental-economist of 77 years, killed himself recently. Weitzman brought, in my opinion, the right perspective to the costs and benefits of acting on climate change, and it was his work that motivated me to start the Life plus 2 meters project. I initially assumed he killed himself in despair over climate chaos, it seems that he was upset to not win the Nobel. (A third possibility is that the award of the Nobel to Nordhaus, who deserves zero respect for his highly flawed model and its recommendation to leave action to future generations,* convinced Weitzman that his work would not get the attention it deserves, thus sealing the miserable fate of our civilization.)

* I want to add more on that comment, which is based on two of Nordhaus’s assumptions. First, he assumes that it’s a good idea to use “market” discount rates to discuss (decidedly non-market) costs and benefits from climate change chaos (CC). I prefer Lord Stern’s view, i.e., that low discount rates (which make future damages from CC more salient in making sacrifices today to avoid CC) are more appropriate for discussing a existential threat like CC. Second, Nordhaus assumes that GDP captures the costs of CC when GDP misses many “ecosystem services” that CC will destroy (e.g., 2/3rds of our oxygen from oceanic phytoplankton). You can read his 2018 Nobel lecture in which he sticks with these flawed assumptions. Weitzman did not.

[Addendum (22 Sep): The lecture link returned a 404. Here’s a copy.]

When comparing these two environmental economists, I would have preferred that Weitzman get the Nobel and Nordhaus get the Ignobel prize, which is “devoted to people who’s research makes people laugh and then think.” Nordhaus’s work is worth thinking about (and laughing at once that’s done), but it’s instead taken seriously, which explains (partially) why the world has taken no substantial steps to slow CC.

How about an example of the dangers from CC? Last week, Hurricane Dorian slapped the Bahamas with winds of up to 300 km/h and a storm surge (more or less instantaneous sea level rise, or SLR) of 8 meters (24 freedom units). That much sea level rise would devastate many coastal cities, and the Bahamas were unlucky.

The Netherlands (where I live) is planning for 1.2 meters of SLR by 2100. What would happen if a 5.5m surge arrived? The whole country would flood, as the country’s famous “delta works” is really only configured to storms bringing a 3m rise. (Listen to my discussion with Ties on this.)

Why is this an emerging (and uncertain) threat? Because SLR is predictable but storms are not. The warming Arctic (see this month’s National Geographic) is making such conditions more and more likely.

My one-handed conclusion is that Nordhaus would be surprised at  the Netherlands getting flooded while Weitzman would not. These reactions explain (to me) why the Nobel went to the wrong guy and my sorrow at losing a real visionary on the dangers of CC.

R.I.P. Marty Weitzman.

Addendum (12 Oct): Tim Hartford shares my views

Addendum (May 2021): Steve Keen and I discuss Nordhaus’s terrible economics (JT archive). Read his paper.

Advice for a graduate student

DA emails:
I’m currently a graduate student/candidate for a Masters in Urban Planning. My interest are in water equity, efficiency, and conservation. My goals are to work in developing countries on water access, sustainable management of water resources and improving the water quality for existing systems. I’m contacting you in hopes of acquiring some advice or contacts in which I can further my knowledge and experience. 
 
If you have any advice or could point me in the right direction on possible research projects or must reads for this field I would greatly appreciate it 
DA’s interests (water equity, efficiency, and conservation) and work goals (work in developing countries on water access, sustainable management of water resources and improving the water quality for existing systems) suggests a two broad themes (aspirational and operational) and thus the different ways of engaging these themes:*
 
  • Equity and access (aspirational): Laws, regulation, outreach, and subsidies
  • Management of efficiency/conservation and quality (operational): Incentives, reporting, engineering and regulatory policy

From these themes, I can give some ideas on work (experience) and readings (knowledge). 

DA can work inside a water-delivery organization on all of these themes. This experience will be hands on, but perhaps not very progressive, given the inherent caution of water firms. DA can also work for the regulator or an advocacy organization. With the regulator, leverage for change is high, but most of the work involves fights over information and interpreting laws and standards. With an advocacy organization, all topics are ready for radical improvement, but leverage for change is low.

When it comes to developing countries, DA will not be able to get a job as a local unless they have local connections, language skills, passport, etc., so the work is likely to be directed at projects (“we have money for this project but not the one you might want”) or building capacity (“this is how we do it in X, you should too”).
