David Byrne on dehumanizing technology

Posted on by

He writes,

I have a theory that much recent tech development and innovation over the last decade or so has an unspoken overarching agenda. It has been about creating the possibility of a world with less human interaction.

He goes on to list examples, such as shopping on line with no salesperson. He points out that with Uber you do not even have to talk to the driver to say where you are going. Online courses reduce interactions with teachers.

You can quibble with some of the examples, but I think he is on to something.

Jean Twenge watch

She writes,

The result is a generation whose members are often afraid to talk to one another, especially about anything that might be upsetting or offensive. If everyone must be emotionally safe at all times, a free discussion of ideas is inherently dangerous. Opposing viewpoints can’t just be argued against; they have to be shut down, because merely hearing them can cause harm.

She adds,

Members of iGen are also taking longer to grow up. As I found in analyzing seven large national surveys of teens, today’s adolescents are less likely to drive, drink, work, date, go out and have sex than were teens just 10 years ago. Today’s 18-year-olds look like 15-year-olds used to. They don’t reach adulthood too early, but they also lack experience with independence and decision-making.

Her book is out, but I have yet to read it. The reviews have been mixed. Tyler calls it new and excellent.

Jonathan Haidt does not mention Twenge in this interview, but his observations parallel hers.

Haidt believes there is a mental-health crisis on campus: ‘I have never seen such rapid increase in indicators of anxiety and depression as we have seen in the past few years’, he says.

The interesting brief interview with Haidt includes this:

‘Kids need conflict, insult, exclusion – they need to experience these things thousands of times when they’re young in order to develop into psychologically mature adults. Every adult has to learn to handle these things and not get upset, especially by minor instances. But in the name of protecting our children we have deprived them of the unsupervised time they need to learn how to navigate conflict among themselves. That is one of the main reasons why kids and even college students today find words, ideas and social situations more intolerable than those same words, ideas and situations would have been for previous generations of students.’

Jeffrey Friedman watch

Posted on by

His latest essay argues that Trump supporters are flag-waving nationalists, not sheet-donning racists. He winds up,

Trumpism represents not a monstrous perversion of modern politics, but an expression of some of its most blandly familiar features.

Mick Jagger sang, “He can’t be a man ’cause he doesn’t smoke the same cigarettes as me.” Let us abbreviate “he can’t be a man” as HCBAM.

Nationalism is HCBAMist toward citizens of other nations, and Friedman would like to talk Trump supporters down from that. But people who take great pride in their opposition to Trump have become HCBAMist toward Trump supporters, and Friedman would like to talk them down from that.

I fear that HCBAMism is very much a part of human nature (recall my recent post on politics as religion). Friedman says that just because behavior is instinctive does not make it right.

We can drop our arbitrary group attachments for rational reasons.

Yes, but a more pessimistic outlook is that when we drop our arbitrary group attachments we then pick up other arbitrary group attachments that have the same consequences, or worse.

The new partisanship

Posted on by

Janet Hook reports in the WSJ,

People who identify with either party increasingly disagree not just on policy; they inhabit separate worlds of differing social and cultural values and even see their economic outlook through a partisan lens.

The wide gulf is visible in an array of issues and attitudes: Democrats are twice as likely to say they never go to church as are Republicans, and they are eight times as likely to favor action on climate change. One-third of Republicans say they support the National Rifle Association, while just 4% of Democrats do. More than three-quarters of Democrats, but less than one-third of Republicans, said they felt comfortable with societal changes that have made the U.S. more diverse.

And these are much larger than the gaps that existed years ago.

Alan Abramowitz and Steven Webster use the term “negative partisanship.”

American politics has become like a bitter sports rivalry, in which the parties hang together mainly out of sheer hatred of the other team, rather than a shared sense of purpose. Republicans might not love the president, but they absolutely loathe his Democratic adversaries. And it’s also true of Democrats, who might be consumed by their internal feuds over foreign policy and the proper role of government were it not for Trump.

What people have come to seek in political news and commentary is anger validation. That is, they want the news to be presented in such a way that it confirms and justifies their anger at political opponents. To say that the market is catering to this desire is an understatement.

Sub-prime crisis or speculator crisis?

Posted on by

Stefania Albanesi, Giacomo De Giorgi, and Jaromir Nosal write,

A broadly accepted view contends that the 2007-09 financial crisis in the U.S. was caused by an expansion in the supply of credit to subprime borrowers during the 2001- 2006 credit boom, leading to the spike in defaults and foreclosures that sparked the crisis. We use a large administrative panel of credit file data to examine the evolution of household debt and defaults between 1999 and 2013. Our findings suggest an alternative narrative that challenges the large role of subprime credit in the crisis. We show that credit growth between 2001 and 2007 was concentrated in the prime segment, and debt to high risk borrowers was virtually constant for all debt categories during this period. The rise in mortgage defaults during the crisis was concentrated in the middle of the credit score distribution, and mostly attributable to real estate investors.

“Real estate investors” means buyers of houses who did not intend to occupy them but were instead buying them for speculation. The non-owner-occupied phenomenon (also known as investor loans) was noted by Andrew Houghwout and others in 2011, and it was something that I suspected back in October 2008. Kevin Erdmann also has pointed out that it was not low-income borrowers who drove the boom and bust.

Criminology as normative sociology

Posted on by

John Paul Wright and Matt DeLisi write,

Liberal political values can shape and distort the research that criminologists do and the public positions that they take. Lee Ellis and Anthony Walsh surveyed several hundred criminologists and found that self-reported ideological perspective was strongly associated with the type of theory that the scholar most often advocated, with liberal criminologists primarily supporting theories that locate the causes of crime in social and economic deprivation. Coauthor John Wright has recently collected data showing that political ideology predicts almost perfectly the policy positions of criminologists. On issues ranging from gun control to capital punishment to three-strikes laws, liberal criminologists showed almost no variation in their beliefs. (Needless to say, they dislike guns, oppose punitive sentences, and vehemently object to the death penalty.)

Of course, it was Robert Nozick who coined the term “normative sociology” as the study of what the causes of problems ought to be.

Later, the authors write,

Reliable evidence tells us that the most effective strategies to reduce crime involve police focusing on crime hot spots, targeting active offenders for arrest, and helping to solve local problems surrounding disorder and incivility. Putting predatory, recidivistic offenders in jail or in prison remains the best way to protect the public—especially those who live in high-crime neighborhoods.

Some day, we will view incarceration as inhumane. But until we come up with an effective alternative, I fear that we will find that non-incarceration is even more inhumane.

My fear about academic economics is that it will evolve in the direction of criminology. I foresee ever-increasing social pressure within the community of academic economists to undertake research that confirms left-wing biases.

Russ Roberts on Bootleggers and Baptists

Posted on by

He offers a primer on the model.

The Baptists give the politicians cover for doing what the bootleggers want. No politician says we should ban liquor sales on Sunday in order to enrich the bootleggers who support his campaign. The politician holds up one hand to heaven and talk about his devotion to morality. With the other hand, he collects campaign contributions (or bribes) from the bootleggers.

He proceeds to give some very depressing real-world examples of how this plays out in public policy.

Variable costs approach zero

Posted on by

Jan De Loecker and Jan Eeckhout write,

We document the evolution of markups based on firm-level data for the US economy since 1950. Initially, markups are stable, even slightly decreasing. In 1980, average markups start to rise from 18% above marginal cost to 67% now. There is no strong pattern across industries, though markups tend to be higher, across all sectors of the economy, in smaller firms and most of the increase is due to an increase within industry. We do see a notable change in the distribution of markups with the increase exclusively due to a sharp increase in high markup firms

Tyler Cowen brought up the paper in order to criticize it. Greg Ip covered the controversy.

Variable costs are costs that increase as the business produces more output. They include costs of materials and the labor cost that is involved in direct production. My explanation for the two-Jans result is that variable costs are tending toward zero in many industries. (I think that this is also Tyler’s explanation, but I prefer to use more specific examples and less technical jargon.)

My notes on the topic.

1. Fifteen years ago, I noticed the trend toward declining variable costs. I wrote an essay called asymptotically free goods, “where research and development costs are high, but the marginal cost of the final product or service is low.” Think of a pharmaceutical that is expensive to develop but cheap to manufacture. Think of cell phone service providers, where the marginal cost of transmitting another gigabyte of data is close to zero. Think of a hospital, where most of the cost is overhead (if the amount of medical services that a hospital were to supply on a given day declined by 1 percent, the amount by which its actual costs would decline is close to zero). Think of an Internet service, such as Facebook, with high costs of development and maintaining a data center but with extremely low cost of adding another user.

The point of the essay is that under marginal cost pricing, these would be free goods. If variable cost approaches zero, then markup over variable cost approaches 100 percent. [update: a commenter points out that this statement was in error. The ratio of price to variable cost approaches infinity as variable cost approaches zero.] (In the case of Facebook, the marginal cost of serving an ad is close to zero, and the markup that it charges advertises therefore approaches 100 percent).

2. When I taught economics in high school, I would say that “price discrimination explains everything.” That is because most businesses do not operate in the textbook world of perfect competition. Instead, firms are focused on recovering fixed costs. To do so, they apply different markups to slightly different versions of products, trying to recover more fixed costs from the less price-sensitive buyers. That is why movie theaters charge so much for popcorn, why airlines have different classes of seats, why cable TV providers offer bundles, and so on.

3. In manufacturing, the share of production workers is declining, but the share of non-production workers is increasing. Overall, we are producing more output with fewer workers on the assembly line (and I would guess that materials costs also are lower).

4. My guess is that, if anything, the two-Jan’s paper understates the trend toward high markups. That is because my guess is that most corporate data allocates more labor to variable cost than really belongs there. Garett Jones pointed out that these days most workers do not produce widgets. Instead, they produce organizational capital. Garett Jones workers are part of overhead, not variable cost.

5. In textbook economics, the term “monopoly power” is pretty much by definition the ability to charge a price above marginal cost. By that definition, it is very hard to think of real-world businesses that do not have monopoly power. If you want to say that the textbook model of perfect competition is baloney sandwich, I would have to agree with you.

6. But lack of perfect competition does not mean that government regulators know better.

7. Lack of perfect competition does not mean that there is no market discipline. There is still competitive discipline, but a lot of it comes in the form of creative destruction rather than in the form of prices being driven down to marginal costs by copycat entry.

8. Government intervention can easily take the form of trying to stop creative destruction. For example, demand that autonomous vehicles be accident-free, rather than merely less dangerous on average than human-driven cars.

Re-reading David Brooks

Posted on by

Almost twenty years after it first appeared, I review Bobos in Paradise.

What Brooks might have foreseen, but did not, was how this Bobo project would play out as it gathered momentum. In the last two decades, we have witnessed the acceleration of the long-term trend toward expansion of the more abstract-oriented industries, such as finance and entertainment, and a decline of the more concrete-oriented industries, such as manufacturing and mining. As a result, the cultural influence of Bobos has soared. The Bobos became insistently cosmopolitan on issues of immigration and foreign relations, increasingly aggressive in their assault on traditional ideas about gender, and increasingly eager to stifle the speech on campus of those with whom they disagree.

Should we miss the working class?

Posted on by

Brink Lindsey writes,

people are not machines, and they don’t like being treated as such. By inducing millions of people to take up factory work and creating a social order in which those millions’ physical survival depended upon their doing such work for most of their waking hours, industrial capitalism created a state of affairs deeply inconsistent with the requirements of human flourishing—and, not unrelatedly, a highly unstable one at that.

…In pursuing the technical efficiency of mass production regardless of its human costs, the class system created by industrial capitalism divided people along very stark lines: those who work with their brains and those who work with their bodies; those who command and those who obey; those who are treated as full-fledged human beings and those who are treated as something less.

I spent two summers working in a plant that produced speakers for sound systems for buildings (think of the music piped in at shopping malls). A lot of the work was with materials that probably were dangerous to one’s lungs, including jute and fiberglass. Maybe my chronic cough comes from that. Otherwise, the work was not as rote as Lindsey depicts, and even when it was rote the time would pass reasonably well. On the plus side, there was no office politics, no ambitious co-workers stabbing you in the back or trying to steal credit for your ideas. But on net, I would tend to agree with Lindsey that we should be happy to see old-fashioned manufacturing production work phase out.

The last time I looked, which was a few years ago, the share of manufacturing production workers (as opposed to managers and supervisors) in the labor force was down to just over 5 percent. Fifty years ago, I believe it was more than 20 percent.

The erstwhile working class has moved in two directions. One direction is white-collar work. However, the other direction is non-employment. To address the latter, Lindsey offers this:

A more humane economy, and a more inclusive prosperity, is possible. For example, new technologies hold out the possibility of a radical reduction in the average size of economic enterprises, creating the possibility of work that is more creative and collaborative at a scale convivial to family, community, and polis. All that hold us back are inertia and a failure of imagination—and perhaps a fear of what we have not yet experienced. There is a land of milk and honey beyond this wilderness, if we have the vision and resolve to reach it.

To me, this sounds like the sort of utopian hope that we held for the Internet twenty years ago. As I pointed out in several posts a week ago, the reality has recently seemed to differ.
