A (surprising) profile, a surprising result,a Maharaja(h) in the Yorkshire Dales, Driverless Cars and (non)ergodicity

Can you guess what this article is about, who has written it, and when?

The dirty little secret on Wall Street is that the men responsible for its current reputation were not exceptionally bad. They were just ordinary people placed in unusual circumstances.

“Knowing somebody” to “get the job done” is older than you thought, is applicable in more places than you’d expect, and last across a longer time horizon than you’d have expected. Well, I don’t know about you, but each of these was true in my case.

The main empirical analysis of this article compares a snapshot of the location of mission stations in Africa in 1903 to the precise locations of projects funded by the World Bank in 1995–2014. The unit of analysis is derived from a grid of 55km×55km square cells covering the African mainland and Madagascar. The results imply that the presence of (at least) one mission station increases the probability that an area is allocated a development project by approximately 50 percent.

A rather macabre excerpt, but to me a revealing one. On “The Maharajah of the Yorkshire Dales

The first ethnically Indian minister in Britain was Parmjit Dhanda. He too found a rural seat, out in the West Country, in Gloucestershire. People were almost always polite and pleasant to him, but one morning he came out and found a severed pig’s head on the bonnet of his car.

The year was 2010.


Vox explains the current state of affairs when it comes to driverless cars, and how long that might take (short answer? A little bit longer, but no idea exactly how long. Sorry.)

There are two core statistics useful for evaluating how advanced a self-driving car program is. One is how many miles it has driven. That’s a proxy for how much training data the company has, and how much investment it has poured into getting its cars on the road.

The other is disengagements — moments when a human driver has to take over because the computer couldn’t handle a situation — per mile driven. Most companies don’t share these statistics, but the state of California requires that they be reported, and so California’s statistics are the best peek into how various companies are doing.

On both fronts, Google’s sister company Waymo is the clear leader. Waymo just announced 20 million miles driven overall, most of those not in California. In 2018, Waymo drove 1.2 million miles in California, with 0.09 disengagements every 1,000 miles. Coming in second is General Motors’ Cruise, with about half a million miles and 0.19 disengagements per 1,000 miles. (Cruise argues that since it tests its cars on San Francisco’s difficult streets, these numbers are even more impressive than they look.)

A topic that more students of economics should know about: (non)-ergodicity.

First is a very micro level concern: behavioural biases. The whole idea of endowment effects and loses aversion make sense in a world dominated by non-ergodic processes. We hate losing what we have because it decreases our ability to make future gains. Mathematics tells us we should avoid being on one of the many losing trajectories in a non-ergodic process.

Tech: Links for 22nd August, 2019

  1. “1. first bionic hand with a sense of touch that can be worn outside a laboratory
    2. development of a new 3D bioprinting technique, which allows the more accurate printing of soft tissue organs, such as lungs
    3. a method through which the human innate immune system may possibly be trained to more efficiently respond to diseases and infections
    4. a new form of biomaterial based delivery system for therapeutic drugs, which only release their cargo under certain physiological conditions, thereby potentially reducing drug side-effects in patients
    5. an announcement of human clinical trials, that will encompass the use of CRISPR technology to modify the T cells of patients with multiple myeloma, sarcoma and melanoma cancers, to allow the cells to more effectively combat the cancers, the first of their kind trials in the US
    6. a blood test (or liquid biopsy) that can detect eight common cancer tumors early. The new test, based on cancer-related DNA and proteins found in the blood, produced 70% positive results in the tumor-types studied in 1005 patients
    7. a method of turning skin cells into stem cells, with the use of CRISPR
    the creation of two monkey clones for the first time
    8. a paper which presents possible evidence that naked mole-rats do not face increased mortality risk due to aging”
    That is an excerpt from an excerpt, but I found the list astonishing. These are advancements from only the field of biology, only from 2018… and as the article goes on to say, only from January 2018. Remarkable. I know very little of how life sciences work, but the article was very informative on that score.
  2. Do Uber and Lyft contribute to congestion? Note the funding agencies.
  3. Benedict Evans on whether Netflix is a TV business or a tech business.
  4. This link comes via MR, and Tyler Cowen said it is Tiebout Twitter. I prefer Voting With your Tweets.
  5. “But perhaps he also sensed that power in society is shifting from the institutions he oversaw, to those that distribute private capital—it wouldn’t be the wrong read, even if it’s an unsettling one.”
    A not altogether pretty look at the VC industry and its evolution over time.
