…who explained why your intro physics class should include computer programming…. I wholeheartedly agree with Rhett–computer simulations need to be a part of the intro science courses…. When we start doing programming, I tell students that this matters because there are only about a dozen problems in physics that you can readily solve exactly with pencil and paper…. And that goes double, maybe triple for engineering, where you can’t get away with the simplifying spherical-cow approximations…. Any really interesting problem in any technical field is going to require some numerical simulation, and the sooner you learn to do that, the better. The best way to handle this is to have it integrated into your intro courses in your chosen major field–the best way to learn to code is to have a problem you need a computer to solve…

Rhett Allain: You Should Be Coding in Your Physics Course: “Let’s talk about the numerical calculations…

…breaking a complicated problem into many smaller (and easier) problems. Since this makes many problems to solve, the simplest strategy is to use some type of computer…. I think it’s an important topic to cover in introductory classes. What are some of the reasons faculty don’t include numerical calculations?… ‘Numerical calculations are too complicated and require too much setup to be used in an intro course.’ I admit that this used to be true—but no longer. In the past, it was a huge pain in the rear to get into some type of computing environment for non-programmers…. But it’s not 1995 any more. Numerical calculations aren’t out of reach of beginning students. They aren’t even out of reach for physics faculty…. Python and VPython…. GlowScript…. Trinket…. There are certainly many other tools…

Preliminary Initial Notes on the Economics of Star Trek

Preliminary Initial Notes on the Economics of Star Trek:

  • Look, 1776 North America was a very rich country by 18th Century standards because of the enormous land to labour ratio, and yet still 75% of our people were farmers engaged in growing your 2,500 calories per day plus essential nutrients plus other things…
  • Today, here in the United States, we are down to 3% of the labour force who are growing our food…
  • Going from 75% to 3% means as far as basic calories and nutrients are concerned we have gone 95% of the way to the Replicator as far as basic calories plus essential nutrients are concerned…
  • Agriculture has been the occupation of most of the human race since the invention of, well, agriculture…
  • Roman legions conquered much of Europe and some of Asia on basically a big loaf of barley bread a day, plus some salt and garlic–plus whatever squirrels they could catch, and whatever greens they could gather where the legions were marching…
  • They were happy to have this diet as long as they had sufficient salt attached to it…
  • That 2,500 calories plus essential nutrients plus enough protein was the destiny for most of human history…
  • That average diet of bare calories and nutrient–even with 75 to 80% of your labour force devoted to producing it, produced adult males whose average height was maybe 5’2″ or 5’3″…
  • Such a diet! If you were to try to give it to your children today Alameda County Child Protective Services would come and take your children away and you would never see them again…
    On comfort:
  • We [lucky enough to be here in the middle-class North Atlantic] have solved scarcity with respect to food, have solved scarcity with respect to clothing…
  • Consider that the average Prussian noble family in the 18th Century had one gown suitable for court appearances to be shared among all of the females–and these are people who are nobles, these are people with a “von” in their surname…
  • Last time I was in Britain, we went to Oliver Cromwell’s house in Ely–the house he lived in when he was parliamentary representative: the ceilings are seven feet tall…
  • When I was 25, my house in Waltham Massachusetts was more comfortable and had many more square feet per person than Oliver Cromwell’s house–plus we had appliances, and we had central heat and air conditioning…
  • Nathan Rothschild, the richest man of the world in the 19th Century, died when he was younger than I am of an infected abscess in his back. We don’t die of infected abscesses.”
  • People regard Riker as a weirdo because he would rather be second-in-command to Picard than to control his own spaceship. And it’s pretty clear that that quest for honor and authority is a feature of society, rather than errors by screenwriters who haven’t gotten the memo…

Must- and Should-Reads:

Might Like to Be Aware of:

Must-Read: Daniel Davies: The shortest Greece post ever

Must-Read: One important question (and answer) are missing from the very sharp Daniel Davies’s latest:

Daniel Davies: The shortest Greece post ever: “It has been suggested… that 10000 words about a bailout…

from 5 years ago… was a bit too much. I disagree…. But… this is the Twitter generation, so here is a very, very condensed version of my “Relitigating the 2010 bailout” series: How much primary deficit financing did Greece get from the troika? Roughly, EUR15bn. How much primary deficit financing could Greece have got from anywhere other than the troika?: Roughly, zero. So, how much did Greece benefit from the troika, in terms of smoothing output and consumption?: Roughly, 6% of [annual] GDP over four years. Is that a lot?: Yes, proportionately, it’s about half as big again as what West Germany received under the Marshall Plan.

The missing question and answer is: How much extra did Greece suffer because its attachment to the eurozone prevented its following the depreciation road to structural adjustment?: 15% of annual GDP x 5 years so far = 75% of annual GDP

And there is also: How much does Germany benefit from the export powerhouse role it could not assume if the DM were not in the eurozone?: I leave that as an exercise for the reader.

Must-Read: Ben Thompson: Tesla Model X Pricing Revealed, Consumer Reports and the Tesla P85D: “Stepping back, when have new things ever not been expensive?…

…Back in 1900 cars were hand-made and cost $1,000, while a horse was only $70. It hardly followed that cars were doomed, or that those building them ought to have f—ed themselves. Moreover, this $132,000 crossover, and the other high-priced Tesla’s that have come before it, are absolutely necessary for the Model 3, and for multiple reasons: –From a technical perspective, every model to date has moved Tesla down the learning curve from the perspective of actually making cars, making batteries, and making software. The importance of this process–and the exponential gains that result–cannot be overstated. –From a financial perspective, the high-priced models sold to-date have helped in two ways: most obviously unit profits can go straight into R&D for future models, but also impressive sales, enthusiastic customers, and rapturous reviews support Tesla’s stock, further issuances of which have been used to pay for launching first the Model S and now the Model X. –Relatedly, and most importantly, from a product perspective, by not prioritizing low prices Tesla has been able to focus on selling a superior experience. This is a big reason why recent low oil prices haven’t put a damper on Tesla’s sales: Tesla’s customers aren’t buying electric vehicles to save on gas! Musk explained this himself in 2006 in a blog post called The Secret Tesla Motors Master Plan (just between you and me)…

Weekend Reading

This is a weekly post we publish on Fridays with links to articles that touch on economic inequality and growth. The first section is a round-up of what Equitable Growth has published this week and the second is work we’re highlighting from elsewhere. We won’t be the first to share these articles, but we hope by taking a look back at the whole week, we can put them in context.

U.S. jobs growth remains too slow

The employment and earnings data released today by the U.S. Bureau of Labor Statistics show that wages are still growing but at too slow of a rate to stem the historical rise in wage inequality. Although job gains are slowly tightening the labor market, the current pace of growth will continue to keep full employment a remote prospect.

Wages increased in August over the last year at a rate of 2.2 percent, similar to last month. And over the past three months, wages have grown at a 1.9 percent rate showing little sign of significant acceleration. Since the beginning of this year, the average wage of production and non-supervisory workers, who make up more than four-fifths of the workforce, has been growing at a slower rate than for the overall private sector, implying an increase in wage inequality.

Two of the industries seeing faster wage growth than the overall private sector are the leisure-and-hospitality sector, where wages increased by 2.9 percent over the last year, and the retail sector, where wages rose by 2.5 percent. Minimum wage increases and political pressures to increase wages in these sectors are among the factors driving wage growth. More than 70 percent of all minimum wage workers are employed in these two industries.

Employment grew by 173,000 in August, or about an average monthly gain of 221,000, over the last three months. Growth at these rates is helpful but not fast enough to secure an employment rate consistent with healthy wage growth any time soon. Next month’s employment release, for September, will mark six full years of consecutive monthly employment growth during the recovery, since October 2010. Yet the employed share of the prime-age population (ages 25 through 54) remains at 77.2 percent, well below even the lowest rate the economy sunk to after the end of the 2001 recession, 78.6 percent.

During a recovery, a healthy economy should be experiencing very rapid growth as it grows and recovers from prior employment losses. But last month the number of employed workers increased by only 1.5 percent at an annual rate, contrasting sharply with prior, more robust recoveries. Three years after the end of the 1990-1991 recession, for example, employment grew consistently by more than 3 percent each month at annual rates. Yet over the last six years, there have been only three months when monthly employment increased at an annual rate of more than 3 percent.

The proportion of working teenagers remains very low, too, at 28.0 percent last month, falling over the course of this year. Looking over the entire post-World War II period, when the earliest comparable data on teen employment begins, the teen employment-to-population ratio has never been so low as it has been during this recovery. In particular, teen employment now is substantially lower than in the late 1960s or 1970s, when minimum wages were higher. In 1968, when the inflation-adjusted minimum wage was at its highest point, 42 percent of the teen population was employed, about 50 percent more than was the case last month. Higher minimum wages than the United States has today were consistent with a much healthier labor market for teens.

The Federal Reserve should focus on the weak labor market later this month when it discusses raising interest rates, as doing so will slow both employment and wage growth. For both teens and the prime-age working population, employment rates remain significantly below rates during the depths of the prior recovery. Only now are hiring rates and quit rates—at 4.0 and 2.2 percent, respectively, in June—similar to levels at the nadir of the previous business cycle ending in 2007. Throughout the subsequent recovery, nominal wage growth (before factoring in inflation) has remained well below rates that preserve workers’ share of national income over the long run.

In addition, recent research shows that raising interest rates depresses the economy more than the stimulus provided by lowering rates, consistent with the idea that it’s harder to “push a string.” As a result, although raising rates too late is easy for the Fed to correct through future increases, raising rates too early may disproportionately stymie the recovery. Both the weak labor market and the asymmetric effects of monetary policy provide reasons for the Fed to avoid raising rates this year.

…will base its interest-rate decisions primarily on domestic considerations. While there is more than the usual degree of uncertainty regarding the magnitude of America’s output gap since the financial crisis, there is comparatively less ambiguity now that domestic inflation is subdued. The rest of the world shares that benign inflation environment. As the Fed prepares for its September meeting, its policymakers would do well not to ignore what was overlooked in Jackson Hole: the need to place domestic trends in global and historical context. For now, such a perspective favors policy gradualism.

Must-Read: Kevin Drum: The Future of Health Care Costs Looks Surprisingly Rosy

Must-Read: Two points: (1) Kevin Drum reveals that he writes his weblog posts not in his bathrobe but in his shorts. (2) Ever since the closing of the health-care expansion frontier opened by Medicare and Medicaid plus the industrialization of the hospital, we have seen a steady if saw-toothed decline in the pace of spending growth–your standard logistic in the share of spending devoted to health care.

The big question for me is: Are we near the asymptote? Or will there be another wave of backlash against narrow networks and bureaucratic blockages of authorizations?

Time will tell!

Kevin Drum: The Future of Health Care Costs Looks Surprisingly Rosy: “You’ve seen various versions of this chart from me…

…perhaps you’d like to see it from a pair of highly-qualified researchers rather than some shorts-clad blogger? Not a problem…. The recent slowdown in health care costs isn’t just an artifact of the Great Recession. That probably helped, but the downward trend far predates the recession. Bottom line: there will still be spikes and valleys in the future, but there’s every reason to think that the general trend of health care costs over the next few decades will be either zero (i.e., equal to overall inflation) or pretty close to it.
