What is the unhappiest day of the week?

by  Tyler Cowen in

It is Sunday, at least according to one study conducted in Germany, by Swedes.  Could it be because there is much less to buy?  Because the cities empty out?  Because walking in nature is overrated?  Because you are supposed to go to church or are supposed to spend more time with family?  Indeed the effect is stronger for married people.  For former East Germans there is not a significant Sunday effect.

When I lived in Germany, Sunday was my least favorite day, as it was in Wellington, New Zealand, although that is not the case living in the United States.

Who buys cosmetic surgery?

by  Tyler Cowen in

Not just the rich:

…cosmetic surgery is now primarily consumed not by the rich, but by the
working and lower-middle classes, sometimes even by the poor. 
According to the American Society for Aesthetic Plastic Surgery (ASAPS),
about 1/3 of cosmetic surgery is consumed by people who make less than
$30,000 a year.  About 70% of it is consumed by people who make less
than $60,000 a year. It is mostly women (90%) and mostly white,
middle-aged women (80% and between 35-55 years old).

Here is a more complete account.  In the Reid bill there is a tax on cosmetic surgery.  In my view cosmetic surgery is not just a zero-sum game but rather it leads to better matches, more matches, and more people who are happy with their looks or with the looks of their partner(s).  It also leads to higher levels of trust. And it's a sector that has, overall, lowered costs over time.

Giovanni Peri’s latest on immigration and productivity

by  Tyler Cowen in

Here is the abstract and it has to do with a Smithian theme, namely division of labor:

Using the large variation in the inflow of immigrants across US states we analyze the impact of immigration on state employment, average hours worked, physical capital accumulation and, most importantly, total factor productivity and its skill bias. We use the location of a state relative to the Mexican border and to the main ports of entry, as well as the existence of communities of immigrants before 1960, as instruments. We find no evidence that immigrants crowded-out employment and hours worked by natives. At the same time we find robust evidence that they increased total factor productivity, on the one hand, while they decreased capital intensity and the skill-bias of production technologies, on the other. These results are robust to controlling for several other determinants of productivity that may vary with geography such as R&D spending, computer adoption, international competition in the form of exports and sector composition. Our results suggest that immigrants promoted efficient task specialization, thus increasing TFP and, at the same time, promoted the adoption of unskilled-biased technology as the theory of directed technological change would predict. Combining these effects, an increase in employment in a US state of 1% due to immigrants produced an increase in income per worker of 0.5% in that state.

Alberta fact of the day

by  Tyler Cowen in

Edmonton and Calgary are among the few metropolitan areas in the developed world that are not connected to comprehensive motorway systems.

Here is much more, on highways in Canada or rather the relative lack thereof.  I am not convinced by his argument that a "bigger and better" highway system is what Canada needs, but I found this interesting reading nonetheless, mostly because it shows how few highways Canada has.

NASA FAQ 2012

by  Alex Tabarrok in

NASA scientists are frequently being asked questions concerning 2012 and for this reason they have created a web page to answer these questions and reassure the public. e.g.

Q: Is there a planet or brown dwarf called Nibiru or Planet X or Eris that is approaching the Earth and threatening our planet with widespread destruction?

A: Nibiru and other stories about wayward planets are an Internet hoax. There is no factual basis for these claims. If Nibiru or Planet X were real and headed for an encounter with the Earth in 2012, astronomers would have been tracking it for at least the past decade, and it would be visible by now to the naked eye. Obviously, it does not exist. Eris is real, but it is a dwarf planet similar to Pluto that will remain in the outer solar system; the closest it can come to Earth is about 4 billion miles.

Sigh…. I too fear for our planet.

Unemployment Breakdown

by  Alex Tabarrok in

The NYTimes has a nice interactive graphic on unemployment rates and changes over time by demographic characteristic.  I am in the category–white men ages 25-44 with a college degree– with almost the very lowest unemployment rate (3.9%).  Just to compare, as pointed out in the comments, black males 15-24 without a high school degree have an unemployment rate of 48.5%.  Check it out.

Fifty Years of Economic History in one Figure

by  Alex Tabarrok in

David Beckworth sums up a lot of recent economic history in one figure.

Spending history

A few thoughts:  I wish Arnold Kling were correct that inflation is around the corner.  We could use some inflation to get back on track.  Nominal wages are simply not flexible enough to get the job done in short order and there is much to fear from populist backlash.

See also the link above for a remarkably similar figure for the OECD which illustrates the US's role of monetary hegemon. 

“The GDP Mirage”

by  Tyler Cowen in

The story, by Michael Mandel, is here.  Excerpt:

While the statistics don't account for it, there's good reason to
suspect intangible investments are falling. Companies are under
pressure to cut costs by reducing R&D expenditures and deferring
other crucial intangibles, notes Hulten. "Because these are expensed,
it looks like a pure win," he says. "You are not seeing the benefits of
the intangibles in the financial statements–only the costs."

There is much more of interest in this article.

Norway Tax Data Now!

by  Alex Tabarrok in

It's the moment nosy Norwegian neighbors have been waiting for — the release of official records showing the annual income and overall wealth of nearly every taxpayer in the Scandinavian country.

In a move that would be unthinkable elsewhere, tax authorities in Norway have issued the ''skatteliste,'' or ''tax list,'' for 2008 to the media under a law designed to uphold the country's tradition of transparency…

Many media outlets use the tax records to produce their own searchable online databases. In the database of national broadcaster NRK, you can type a subject's name, hit search and within moments get information on what that person made last year, what was paid in taxes and total wealth….

The information had been available to media until 2004, when a more
conservative government banned the publication of tax records. Three
years later, a new, more liberal government reversed the legislation
and also made it possible for media to obtain tax information digitally
and disseminate it online.

There has got to be more than one dissertation here.  Aside from the obvious issues of studying the distribution of wealth over time and cross-sectionally the three year break raises possibilities such as testing whether making salary and wealth information public encourages people to work more or less and  whether public information about income increases or decreases inequality.

Perhaps most interesting–does conspicuous consumption fall and efficiency increase in a society in which income is conspicuous?

Health Data Now!

by  Alex Tabarrok in

It's well known that medical spending is highly variable but so are medical outcomes.  Here is Begley and Interlandi in Newsweek:

After we interviewed dozens of oncologists, pored over published papers, and obtained outcomes data that cancer centers have never before made public, it became clear that for these cancers there are indeed significant outcome differences depending where you are treated.

Five years after surgery for prostate cancer, for instance, 72 percent of men treated at leading hospitals are alive, compared with 62 percent of those treated elsewhere. Scrutinizing data from specific cancer centers reveals even greater gaps. Five-year survival for stage IV prostate cancer is 71 percent at Fox Chase, for instance, but 38 percent nationally. For stage IV breast cancer, the respective figures are 28 percent and 19 percent–an almost 50 percent edge. For stage IV cervical cancer, five-year survival is 33 percent at the Cleveland Clinic vs. 16 percent nationally.

Some of this is probably due to differences in patient characteristics but it could go either way – the better hospitals often get the hardest to treat cases.

Many hospitals hide this data (or "fail" to collect it which amounts to much the same thing) but there are some good rules of thumb such as looking for hospitals that specialize in certain procedures and thus perform many of them (there are large economies of scale in quality).  Patients can also find information about which hospitals closely follow best practices (kudos to Medicare for this data and see here for a mashup with Google maps) although the measures used are probably the ones that are easiest to collect and not the ones that correlate best with mortality.

Nevertheless, providing information does seem to drive change if only from the shame that a hospital receives when it is found not to be following best practices.  It's true that report cards can cause problems when the drive to get a better score causes hospitals to be more reluctant to treat sicker patients but better data on patient characteristics (stage of cancer etc.) and better process/treatment information can alleviate this problem. In fact, all hospitals should be required to provide standardized information for all patients on patient characteristics, treatments and outcomes.  Only by making outcome information public will hospitals have the incentive and researchers have the ability to develop more accurate report cards.  In short, I cannot think of a simpler change that would improve health care to as great an extent as freeing the data.

Payroll tax cuts and gross job flows

by  Alex Tabarrok in

In the comments section to my last post a number of people argued that in the current recession firms simply don't have the sales to support a larger workforce so a small reduction in labor costs from a payroll tax cut isn't going to increase employment appreciably.

The argument sounds plausible but the premise is wrong – in fact, lots of firms are selling and hiring.  In July, for example (the most recent data), firms hired over 4 million workers.  Yes, 4 million.  Even in declining sectors like construction there were 346,000 new hires in July alone.  In the 12 months preceding July, firms hired 51.3 million workers.  The problem of course is that during the same time there were 56.6 million job separations (quits, layoffs, retirements) for a net job loss of 5.3 million.

Even though we are still experiencing a daily net loss of jobs it's important to remember that there are about 200,000 hires every working day  Lots of firms are hiring.  In order to increase employment a payroll tax cut need not shift firms "from firing to hiring" it need only increase the hiring rate of those firms already hiring or on the margin of hiring.

The data is from the JOLTs survey which releases more data tomorrow.  The uber-source on job flows is Davis and Haltiwanger and their extensive work with co-authors.  For a good, non-technical, introduction to this and related topics I recommend, The Natural Survival of Work,
