Ideological bias and argument from authority among economists

That is the topic of a new paper by Mohsen Javdani and Ha-Joon Chang, here is part of the abstract:

Using an online randomized controlled experiment involving economists in 19 countries, we examine the effect of ideological bias on views among economists. Participants were asked to evaluate statements from prominent economists on different topics, while source attribution for each statement was randomized without participants’ knowledge. For each statement, participants either received a mainstream source, an ideologically different less-/non-mainstream source, or no source. We find that changing source attributions from mainstream to less-/non-mainstream, or removing them, significantly reduces economists’ reported agreement with statements. This contradicts the image economists have of themselves…

And from the paper:

Consistent with our overall findings, we find that for all but three statements, changing source attributions to a less/non-mainstream source significantly reduces the agreement level. The estimated reductions range from around one-tenth of a standard deviation to around half of a standard deviation.

The largest agreement reduction is for this sentence:

“Economic discourse of any sort — verbal, mathematical, econometric — is rhetoric; that is, an effort to persuade.”

You also can test which kinds of authority reassignation alter the level of agreement.  And thus:

We find that the estimated ideological bias among female economists is around 40 percent less than their male counterparts.

The countries where economists exhibit the highest ideological bias are Ireland, Japan, Australia, and Scandinavia, where for Austria, Brazil, and Italy the ideological bias is smallest.  South Africa, France, and Italy are most conformist to mainstream opinion.

It is a wordy and poorly written paper, and they don’t consider the possibility that deference to authority perhaps is the rational Bayesian move, not the contrary.  Still, it has numerous results of interest.  Here is the authors’ blog post on the paper.

Are property rights in elephants working out after all?

To understand why these reasonable-sounding proposals should be rejected, consider what has happened to elephant numbers since CITES most recently authorised some legal trade, when Botswana, Namibia and South Africa were allowed in 2007 to sell a fixed amount of ivory to Japan, as a one-off. Elephant numbers started falling again. A survey conducted in 2014-15 estimated that elephant numbers had fallen by 30% across 18 countries since 2007; another estimated a decline of over 100,000 elephants, a fifth of the total number, between 2006 and 2015. Increased poaching was at least partly to blame.

These numbers suggest that the existence of even a small legal market increases the incentive for poaching. It allows black-marketeers to pass off illegal ivory as the legal variety, and it sustains demand. The biggest market is in China. Last year the government banned domestic sales of ivory, but its customs officials seize a lot of smuggled products—notably from Japan, which licensed as a market in 2007. For the poachers, ivory is fungible. If it is hard to secure in Zambia or Botswana, another country’s elephants will be in the gun-sights. Congo, Mozambique and, especially, Tanzania, have seen sharp declines. Unfair though it is, countries with better-run conservation programmes are, in effect, paying for the failings of those with feeble institutions.

That is from The Economist.  Yet there is another twist:

In the long run technology can help make trade compatible with conservation. In better-resourced national parks, drones are used to make it easier for rangers to spot poachers. DNA testing of ivory shipments can establish where they came from, and thus whether they are legal. As prices fall and countries get richer, both technologies are likely to spread.

Travel markets in everything

Since launching IntroverTravels in South Dakota nearly three years ago, Marek has planned a wide array of trips for his clients, from tours of Vietnam and Thailand focused on cuisine, to more adventurous wildlife-watching itineraries in South Africa and the Galapagos. “They tend to be remote places where there’s an absence of people or external stimuli. You can get back to nature, contemplate history or experience the culture of a new place,” Marek says.

His clients tend to be “social introverts,” people who enjoy activities but need to be alone afterward to recharge.

And:

When the group meets, Renzi has them all agree to a few specific principles, including, she says, “Honour one another’s needs and preferences for personal time and space and right to silence, and encourage one another to take personal time and skip group activities as needed. Be open to different belief systems, ways of behaving, communication styles.”

The trips are usually capped at 16 people, and many now have waiting lists. “The demand has certainly been growing,” Renzi says.

Rhino bond markets in everything

Conservationists have started marketing a five-year rhino bond, which bankers say will be the world’s first financial instrument dedicated to protecting a species.

Investors in the $50m bond will be paid back their capital and a coupon if African black rhino populations in five sites across Kenya and South Africa increase over five years. The yield will vary depending on changes in the rhino population, which has fallen rapidly since the 1970s.

The bond is likely to have different categories of investment, with some investors taking a “first loss” position. If rhino numbers drop, those investors will lose their money depending on the scale of the decline and the terms of their investment, while investors in other categories will be repaid.

Average annual change in total factor productivity between 1990 and 2014

Here are the estimates from Penn World Tables, only selected countries are presented:

Sri Lanka 2.48

China 2.40

Poland 1.70

Uruguay 1.61

Romania 1.61

United States 0.89

Brazil -0.12

South Africa -0.53

Mexico -0.82

Ukraine -1.20

A few points.  First, I still believe Sri Lanka is an undervalued development story, in spite of recent developments.  Second, the economy of Poland is not discussed enough.  Third, other sources confirm similar numbers for Mexico, arguably because misallocations of capital and labor have increased due to the growing size of the informal sector.  Fourth, there are far too many other nations in the negative column.

Those numbers are reproduced in “Productivity in Emerging-Market Economies: Slowdown or Stagnation?”, by José de Gregorio, in the new and interesting volume Facing Up To Low Productivity Growth, edited by Adam S. Posen and Jeromin Zettelmeyer.

Markets in everything those new service sector jobs

TITUSS BURGESS doesn’t like to travel and says he knows “zero” about South Africa, which would seem to make him an unlikely host for a 10-day tour of that nation, especially one that costs nearly $27,000 a head. But on a chill March night, the actor, best known for his role as Titus Andromedon on the Netflix series “Unbreakable Kimmy Schmidt,” patiently posed for selfies with travel journalists at a Manhattan wine bar to kick off Heritage Tours’ new Spotlight Series of trips. The company describes the tours as “immersive small-group experiences enhanced by the presence of expert personalities and influencers.”

…While Mr. MacMillan says that the hosts for his trips were chosen for their connection to the destinations, the link can seem tenuous. Courtney Reed, who played Princess Jasmine in Disney ’s “Aladdin” on Broadway will be hosting a trip to Spain focused on wine, fashion and food. She’s never been to Spain, but is “extra thrilled” about going. “I think my role is just to provide social ambience,” she said. “I’m a very easygoing person and I can create extra flair just having fun and appreciating our surroundings. I’m like a cheerleader….We’re going to have a blast!”

…Other travel companies are hitching their wagons to stars who don’t merely gild the travel experience, but add bona fide knowledge or expertise. “There’s only so much caviar and champagne you can give passengers, so we like to enrich their experience in an intelligent way,” said Barbara Muckermann, chief marketing officer of Silversea Cruises. The cruise line, which has at least one expert lecturer on each of its ships, invited nine artists, writers and other creative types including authors Paul Theroux, Pico Iyer and Saroo Brierley to make appearances during its 133-day World Cruise 2019. Besides giving lectures, each is contributing to a commemorative anthology that Silversea line is creating for the passengers.

The Ethics of Resistance to State Injustice

The excellent Jason Brennan with a short introduction to his new book, When All Else Fails: The Ethics of Resistance to State Injustice:

Imagine a situation in which a civilian commits an injustice, the kind against which you believe it is permissible to use deception, subterfuge or violence to defend yourself or others. For instance, imagine your friend makes an improper stop at a red light, and his dad, in anger, yanks him out of the car, beats the hell out of him, and continues to strike the back of his skull even after your friend lies subdued and prostrate. May you use violence, if it’s necessary to stop the father? Now imagine the same scene, except this time the attacker is a police officer in Ohio, and the victim is Richard Hubbard III, who in 2017 experienced just such an attack as described. Does that change things? Must you let the police officer possibly kill Hubbard rather than intervene?

Most people answer yes, believing that we are forbidden from stopping government agents who violate our rights. I find this puzzling. On this view, my neighbours can eliminate our right of self-defence and our rights to defend others by granting someone an office or passing a bad law. On this view, our rights to life, liberty, due process and security of person can disappear by political fiat – or even when a cop has a bad day. In When All Else Fails: The Ethics of Resistance to State Injustice (2019), I argue instead that we may act defensively against government agents under the same conditions in which we may act defensively against civilians. In my view, civilian and government agents are on a par, and we have identical rights of self-defence (and defence of others) against both. We should presume, by default, that government agents have no special immunity against self-defence, unless we can discover good reason to think otherwise.

I think it helps in answering this question to think of other countries say South Africa under Apartheid or China today among the Uighur in Xinjiang province…then be consistent. Note that resistance to state injustice may be unwise even when it is ethical.

Meet the Pioneers

Here are the winners from the first Pioneers tournament, summarized here:

In the short 3 months since its launch, Pioneer has garnered a global reach. Our first tournament featured applicants from 100 countries, ranging from 12 to 87 years old. Almost half of our players hailed from countries like India, UK, Canada, Nigeria, Germany, South Africa, Singapore, France, Turkey, and Kenya. Projects were spread across almost every industry — AI research, physics, chemistry, cryptocurrency and more.

They are a remarkably impressive group, here is one example:

Clark Urzo (23, Philippines)

Clark is making a programming language for physics. The idea is to enable anyone who can code to contribute to serious physics research (for example, simulations of gravitating systems). This opens up the field to the wondrous forces of open source and promotes open and accountable science along the way.

Noteworthy: Clark has an insanely impressive trajectory. He learned to code when he was 12. By 16, he was doing Laplace transforms, tinkering with Arduinos, reading Marx and Nietzsche, and taught himself conversational German. He co-founded a VR company by 19.

Or:

Harshu Musunuri (18, USA)

Harshu is creating synthetic materials to improve the diagnosis, treatment, and prevention of sepsis, a leading cause of death in hospitals around the world. Unlike other approaches, these materials don’t require refrigeration and enable low-cost toxin capture in resource-poor settings.

Noteworthy: Harshu comes from a humble background: she was born to an electrical engineer and an elementary school math teacher in a small village in South India. But her work is anything but humble. In her short career, she’s done research with NASA’s JPL, built a seizure detection app for epileptic patients and is now working on a project with the potential to save thousands of lives. She’s also a hacker at heart: when she lacked the formal lab tools to braze at high temperature, she used the exhaust vent of a ceramic kiln.

The overall lesson is that there is a great deal of undiscovered talent out there, and also that some people are out there discovering it!  And if you wish to apply to round two, just follow the instructions at the top link.

Procurement and compliance costs (from the comments)

From my time in both the military and healthcare I can say that the biggest problem are the compliance costs.

For example, I have a phone app that allows me to send texts. We pay very good money to have said app. It does nothing that my phone cannot innately do – except be HIPAA compliant. EMR software is clunky, an active time suck, and adds little or no value … but we are required by law to use it. In each case there are scads of less specific programs out there which are insanely cheaper and more functional, but those programs cannot justify the costs of becoming compliant for a small niche of their business.

In the military we had similar difficulties. If you want systems to be secure, you need to pay extra as the marketplace does not do real security for consumer goods. Likewise, if you worry about logistical tails, building in assured access drastically increases costs.

And I fully suspect that prices will continue to diverge. As ever more of the internet ends up in a giant interconnected mess there will be fewer people able to code in a secure fashion. There will be fewer parts of the ecosystem that can be used by security conscious actors.

Then we get to actual procurement itself. People worry that arcane institutions will somehow make off with lots of money and spend it either poorly or nefariously. Absent easily observed price and cost data in both sectors we began developing rules. These rules drive firms out of the market (e.g. we needed some light interior remodeling to comply with a regulation that specified inches between things, the contractor who has been most affordable and highest quality refused to bid because the hassle on his side was too great). Eventually the rules become too complicated and you start needing specialists to interpret them. Costs skyrocket and firms abuse rules to pad profits. Then the lawyers get involved and things get more expensive. Again, medical and military consumers become a captive market facing greater monopoly as fewer firms can navigate the thicket of rules to even try to make money.

Then we have the problem that people look at these sectors and say that it is public money. All public money should help with goal X (e.g. going “green”, affirmative action, boycotting South Africa/Israel, patriotism, “America first”) and then we become even more overly constrained. Find vendors who meet one hurdle is hard, finding ones that meet 30 is nigh unto impossible unless the vendor is engineering the firm to market solely to this niche – and charging monopoly rates as his reward.

Any single thing would not be too bad for prices, but the marketplace in general is diverging from military and healthcare. Even education is diverging with mandates in FERPA and political business constraints. We have pretty effectively restricted supply, why exactly would we not expect an increase in cost?

That is from “Sure.”

Envy and status in politics

2. People will oppose policies that benefit themselves and their community if they think it will lower their within-group status. 

McClendon uses survey data from South Africa and the United States to show that status motivations change the way that people think about redistributive economic policies. This is even true within ethnic groups, including marginalized ethnic groups like African Americans. As McClendon notes:

“The worse off people are than their coethnic neighbors, the more supportive they are of greater redistribution (regardless of how personally costly this support is); the better off people are than their coethnic neighbors, the less supportive they are of redistribution.”

In other words, even when a policy might make someone materially better off (by, say, improving their housing conditions), they are likely to oppose it if the government doing so for everyone in their community would harm their relative status position.

That is from Laura Seay at The Washington Post, drawing on work from the new Envy in Politics, by Gwyneth H. McClendon.  I have just ordered that book.

*Divided: Why We’re Living in an Age of Walls*

That is the new book by Tim Marshall, yes Trump and Israel and the like, but it goes much further than that.  Here is one excerpt:

Since 1971, Assam’s population has more than doubled, from 14.6 million to over 30 million, much of which is due to illegal immigration.  Hindu nationalists have argued that the area might have a Muslim majority by 2060.  In 2015 there were 19 million Hindus and 11 million Muslims, nine of the twenty-seven districts being Muslim majority.  Equally importantly, the 2017 census showed that people who are ethnically Assamese are now a minority in the state as a whole, and as people continue to arrive their proportions will continue to drop.

This is a depressing but thought-provoking book.  Bangladesh, by the way, is smaller than the state of Florida, but has 165 million people.  And I had not known there are about 800,000 Nigerians in South Africa.  You can order the book here.

The safety net in Ethiopia

They are participants in Ethiopia’s Urban Productive Safety Net Project, which was launched in 2017 and is among the largest social programmes in sub-Saharan Africa (outside South Africa) designed specifically for urban areas. About 400,000 poor Ethiopians in 11 cities are already enrolled. The government hopes it will eventually help 4.7m people in almost 1,000 towns. Beneficiaries are selected by a neighbourhood committee based on how poor and vulnerable they are. In addition to the paid work, they also receive training. Those who want to start their own businesses are given grants.

Safety-nets, in one form or another, have proliferated across Africa in recent years. Spending on them in sub-Saharan Africa now amounts to about 1.5% of GDP (see chart). In Tanzania 10% of the population is covered by its safety-net (at a cost of just 0.3% of GDP)…

Ethiopia’s programme is a step towards building a national social-security system that will, in time, replace a hotch-potch of small ones. It builds on Ethiopia’s flagship rural safety-net, which is the largest of its kind on the continent and covers some 10m poor people in the countryside (out of a total population of about 102m). The government has committed $150m to fund the new scheme and the World Bank has stumped up the remaining $300m needed for the first five years. Ethiopia hopes that within ten years it will no longer need help financing the programme.

Here is more from The Economist.  You can think of this as further evidence of state capacity in Ethiopia.
