Data Source

In India, for example, the number of taxpayers in relation to voters in the economy has been about 4-4.5% for a long time.

That is from an in-depth discussion about the Indian economy between Karthik Muralidharan and Arvind Subramanian (Chief Economic Adviser, Government of India). The reference is to income tax, of course. It’s a great discussion and the best place to begin if you want to understand the Indian economy today.

There is a newly published paper by Andrew Beauchamp:

The U.S. abortion market has grown increasingly concentrated recently, while many states tightened abortion laws. Using data on abortion providers, I estimate an equilibrium model of demand, price competition, entry and exit, to capture the effect of regulation on industry dynamics. Estimates show regulations played an important role in determining the abortion market structure and evolution. Counterfactual simulations reveal increases in demand-aimed regulation were the most important observed factor in explaining recent abortion declines. Simulating Utah’s regulatory regime nationally shows tightening abortion restrictions can increase abortions in equilibrium, mainly through tilting the competitive landscape toward low-price providers.

Balkans fact of the day

Which three economies in Europe have the lowest employment to population ratio, circa 2013?

Greece, Croatia, and Serbia comes in last.

That is from the World Bank and ultimately Eurostat, see p.5 (pdf).

You will note of course that Croatia and Serbia have their own floating rate currencies.  In Serbia the measured unemployment rate is about nineteen percent and a few years ago was above twenty-five percent.

While I do usually favor floating currencies, there are limits to what they can accomplish when other policies are bad.  If you are wondering, the rate of inflation in Serbia has been falling from an average of about seven percent to about two percent.  Wages in the country are often sticky and public sector jobs on average pay higher than private sector jobs (see the first link).  Exports and productivity are weak.

By the way, here is my earlier post which covers unemployment in Jamaica.

Tsuyoshi Shimmura, Shosei Ohashi, and Takashi Yoshimura have a new paper:

The “cock-a-doodle-doo” crowing of roosters, which symbolizes the break of dawn in many cultures, is controlled by the circadian clock. When one rooster announces the break of dawn, others in the vicinity immediately follow. Chickens are highly social animals, and they develop a linear and fixed hierarchy in small groups. We found that when chickens were housed in small groups, the top-ranking rooster determined the timing of predawn crowing. Specifically, the top-ranking rooster always started to crow first, followed by its subordinates, in descending order of social rank. When the top-ranking rooster was physically removed from a group, the second-ranking rooster initiated crowing. The presence of a dominant rooster significantly reduced the number of predawn crows in subordinates. However, the number of crows induced by external stimuli was independent of social rank, confirming that subordinates have the ability to crow. Although the timing of subordinates’ predawn crowing was strongly dependent on that of the top-ranking rooster, free-running periods of body temperature rhythms differed among individuals, and crowing rhythm did not entrain to a crowing sound stimulus. These results indicate that in a group situation, the top-ranking rooster has priority to announce the break of dawn, and that subordinate roosters are patient enough to wait for the top-ranking rooster’s first crow every morning and thus compromise their circadian clock for social reasons.

In case you had any doubts.  The pointer is from Michelle Dawson.

A long look at short-termism

by on July 30, 2015 at 1:45 am in Data Source, Economics | Permalink

That is the title of a working study from Credit Suisse (pdf), here is one excerpt:

The problem is that short-termism is very difficult to prove. As we will see, many of the common perceived symptoms of short-termism don’t hold up to scrutiny, and there are some legitimate reasons for the shortening of time horizons. While there remains plenty of room for improvement, especially when it comes to incentives, the issue of short-termism deserves more care than it has received in the popular discourse. With little exception, the debate appears to be very one-sided.

Here is another good bit of many:

Were compensation the simple root of the problem, then correction through regulation or other market forces would be relatively straightforward. But a link between pay and termism is difficult to establish. Academic research shows that CEO pay has closely followed the size of the firms in the economy independent of the form of remuneration. Further, executive compensation has moved toward long term incentives, boards of directors are more independent than in the past, and governance committees are “nearly universal.” Reviewing the challenges of conclusively demonstrating short-termism, one scholar wrote, “[I am] aware of no empirical evidence establishing that executive pay term is inadequately focused on long-term performance from either a shareholder or societal perspective, systematically.”


To summarize, a proper test of short-termism should address the micro-macro problem by relying on the outcome of the market pricing process rather than the views of individuals. While many constituents feel the market is short-term oriented—a feeling that has been expressed through the decades—asset prices don’t support this sense.

In fact there is a good deal of evidence that the sectors which require the most long-term attention attract investors and boards who understand that need.  Here is my previous post on this issue.

For the pointer I thank Michael Mauboussin.

Does Fair Trade help poor workers? Probably not says Don Boudreaux in this excellent, short video from the Everyday Economics series at Marginal Revolution University.

As is well known, however, Don is a rabid, free-market economist with ideological blinders who has been captured by corporate interests. So let’s ignore what Don says and consider what William MacAskill, author of Doing Good Better (reviewed earlier this week) has to say. No one can fault MacAskill’s charitable bona-fides:

MacAskill’s own pledge is to donate everything he earns above about $35,000 per year, adjusted using standard economic measures for inflation and cost of living, to the organizations that he believes will do the most good. Since his bar is roughly at the UK median income—such that half the population earns more each year, and half the population earns less—he’s certainly not condemning himself to a life of hardship; rather, he is pre-committing to staying roughly in the middle of the national income distribution even as his earnings go up over time.

That said, his pledge means giving away 60 percent of his expected lifetime earnings.

When I ask him the inevitable questions about whether this isn’t rather a lot to sacrifice for one person, MacAskill shrugs modestly and smiles broadly. “Imagine you’re walking down the street and see a building on fire,” he says. “You run in, kick the door down—smoke billowing—you run in and save a young child. That would be a pretty amazing day in your life: That’s a day that would stay with you forever. Who wouldn’t want to have that experience? But the most effective charities can save a life for $4,000, so many of us are lucky enough that we can save a life every year through our donations. When you’re able to achieve so much at such low cost to yourself…why wouldn’t you do that? The only reason not to is that you’re stuck in the status quo, where giving away so much of your income seems a little bit odd.”

So what are MacAskill’s views on Fair Trade? Why they are the same as Don’s!

…when you buy fair-trade, you usually aren’t giving money to the poorest people in the world. Fairtrade standards are difficult to meet, which means that those in the poorest countries typically can’t afford to get Fairtrade certification. For example, the majority of fair-trade coffee production comes from comparatively rich countries like Mexico and Costa Rica, which are ten times richer than the very poorest countries like Ethiopia.

….In buying Fairtrade products, you’re at best giving very small amounts of money to people in comparatively well-off countries. You’d do considerably more good by buying cheaper goods and donating the money you save to one of the most cost-effective charities…

The latest World Trade Monitor showed the volume of world trade falling in May by 1.2 per cent. It slid in four out of five months in 2015 and risen just 1.5 per cent in the past 12 months — less than the growth in global output and far below the long-term average of about 7 per cent a year.

The problem has been getting worse for some time. Trade bounced back fairly well in 2010 after the global recession but it has disappointed ever since, growing by barely 3 per cent in 2012 and 2013. Now it seems the world cannot manage even that.

That is from Stephanie Flanders.

Annual real growth in gross capital formation hit 6.6 per cent in 2014, down from 10.2 per cent in 2013 and a peak of 25 per cent in 2009.

Thomas Gatley, China corporate analyst at Gavekal Dragonomics, a research firm, estimates that so far this year GFCF may be running at around 4 to 5 per cent.

That is from James Kynge at the FT.  Here is from Ambrose Evans-Pritchard:

David Cui, from Bank of America, said $1.2 trillion of stock holdings are being carried on margin debt. This is 34pc of the free float of the Shanghai and Shenzhen stock markets. “When the market ultimately settles at a level that can be sustained on fundamental reasons, we expect that the financial system may wobble, due to high contagion risk,” he said.

Mr Cui said the brokers and trusts have barely 1.6 trillion yuan ($260bn) to absorb losses and may be overrun. “Given the particularly thin front line of the financial institutions, we suspect that it’s a matter of time before banks may have to face the music,” he said.

This in turn risks setting off a “bank run” on the shadow banking system as investors lose trust in wealth management funds, fearing that their deposits in the $2.1 trillion industry no longer have an implicit guarantee.

As Arnold Kling would say, have a nice day…

Around 97% of existing yuan-denominated bonds hold ratings of double-A to triple-A—the best a company can get.

That is from Fiona Law, cited by Christopher Balding, and ultimately Alex Frangos, those are ratings from Chinese sources.  Law reports:

With nine Chinese ratings firms to choose among, “bond issuers are encouraged to pick the highest ratings among agencies,” said Guan Jianzhong, chairman of Dagong Global, the country’s third-biggest ratings company in terms of market share. The fact that the bonds are rated double-A-minus or above, they “are not without risks,” he said.

By the way, the Shanghai Composite Index closes down 8.5%.

We’re going to be hearing more about this topic I suspect, so let’s start by looking at some of the evidence.  For now I’ll turn the microphone over to Xuemin (Sterling) Yan and Zhe Zhang (pdf):

We show that the positive relation between institutional ownership and future stock returns documented in Gompers and Metrick (2001) is driven by short-term institutions. Furthermore, short-term institutions’ trading forecasts future stock returns. This predictability does not reverse in the long run and is stronger for small and growth stocks. Short-term institutions’ trading is also positively related to future earnings surprises. By contrast, long-term institutions’ trading does not forecast future returns, nor is it related to future earnings news. Our results are consistent with the view that short-term institutions are better informed and they trade actively to exploit their informational advantage.

And here is from the Geoff Warren 2014 survey (pdf):

The link between investor short-termism and corporate myopia is not clear cut – While there is some evidence in support of such a link, it is by no mean compelling. Laverty (1996) examines arguments on the existence of short-termism, and points out there is: (1) no clear evidence of flawed short-term oriented management practices; (2) only mixed evidence that stock market myopia encourages corporate short-termism, noting for instance findings of positive stock market reactions to long-term investment by some papers; and, (3) an absence of empirical support for the supposed influence of ‘fluid capital’ on corporate behaviour.

Results of a survey of company management by Marston and Craven (1998) also question the extent to which institutional investors are short-term in focus. While their survey uncovers a perception that sell-side (broking) analysts are focused on the short-term, company management did not consider this the case for buy-side analysts and fund managers. When asked if the buy-side was too concerned with short-term profit opportunities, only 21% agreed while 53% disagreed.

There is more evidence to consider, but I will start by introducing the idea that the standard anti-publicly traded company tropes are not self-evidently true, or at the very least we do not know them to be true.

They are not good, as evidenced by a new paper by Buggle and Nafziger (pdf):

This paper examines the long-run consequences of serfdom in the countries of the former Russian Empire. We combine novel data measuring the intensity of labor coercion on the district level in 1861 with several intermediate and present-day outcomes. Our results show that past serfdom goes along with lower economic well-being today. We apply an instrumental variable strategy that exploits the transfer of serfs on monastic lands in 1764 to establish a causal link between past serfdom and current economic development. Tracking the evolution of city populations throughout Soviet times corroborates the finding of persistent economic differences. Furthermore, our results suggest a political economy mechanisms linking higher historical economic inequality with worse public goods provision (roads and education), as well as lower urbanization and structural change towards factory production, as explanation for this persistence. We do not find differences in contemporaneous cultural attitudes and preferences.

The pointer is from Pseudoerasmus.

Interesting but worrying too:

The SmartGPA study uses passive sensing data and self-reports from students’ smartphones to understand individual behavioral differences between high and low performers during a single 10-week term. We propose new methods for better understanding study (e.g., study duration) and social (e.g., partying) behavior of a group of undergraduates. We show that there are a number of important behavioral factors automatically inferred from smartphones that significantly correlate with term and cumulative GPA, including time series analysis of activity, conversational interaction, mobility, class attendance, studying, and partying. We propose a simple model based on linear regression with lasso regularization that can accurately predict cumulative GPA. The predicted GPA strongly correlates with the ground truth from students’ transcripts…Our results open the way for novel interventions to improve academic performance.

That is from a new paper by Rui Wang, Gabriella Harariy, Peilin Hao, Xia Zhou, and Andrew T. Campbell (pdf).  Class attendance, by the way, does not predict grades very well.

Rent Control in Stockholm

by on July 24, 2015 at 7:31 am in Data Source, Economics | Permalink

Here’s an interesting letter from “Stockholm” to Seattle

Dear Seattle,

I am writing to you because I heard that you are looking at rent control.

Seattle, you need to ask your citizens this: How would citizens like it if they walked into a rental agency and the agent told them to register and come back in 10 years?


I’m not joking. The image above is a scan of a booklet sent to a rental applicant by Stockholm City Council’s rental housing service. See those numbers on the map? That’s the waiting time for an apartment in years. Yes, years. Look at the inner city – people are waiting for 10-20 years to get a rental apartment, and around 7-8 years in my suburbs. (Red keys = new apartments, green keys = existing apartments).

Stockholm City Council now has an official housing queue, where 1 day waiting = 1 point. To get an apartment you need both money for the rent and enough points to be the first in line. Recently an apartment in inner Stockholm became available. In just 5 days, 2000 people had applied for the apartment. The person who got the apartment had been waiting in the official housing queue since 1989!


In addition to Soviet-level shortages, the letter writer discusses a number of other effects of rent controls in Stockholm including rental units converted to condominiums and a division of renters into original recipients who are guaranteed low rates and who thus never move and the newly arrived who have to sublet at higher rates or share crowded space. All of these, of course, are classic consequences of rent controls.

Addendum: More details on Sweden’s rent-setting system can be found here, statistics (in Swedish) on rental availability in Stockhom are here and a useful analysis of the Swedish housing crisis with more details on various policies (e.g. new construction is exempt for 15 years but there isn’t nearly enough) is here. Jenkins wrote a comprehensive review of the literature on rent controls in 2009 that echoed what Navarro said in 1985 “the economics profession has reached a rare consensus: Rent control creates many more problems than it solves.”

Hat tip to Bjorn and Niclas who confirmed to me the situation in Stockholm and to Peter for the original link.

The share of teen girls who reported they’ve had sex at least once dropped from 51 percent in 1988 to 44 percent in 2013, they found. Abstinence was more pronounced among the guys: 60 percent of teen boys in 1988 said they’d had sex, compared to 47 percent in 2013.

That is from Paquette and Cai, the underlying CDC study is here.  One major hypothesis is that teen sex has declined because smart phone usage is up.  Teens are both better informed about the risks of sex and…they have something else to do.

Casey Warman and Christopher Worswick have a new and interesting NBER paper on Canadian immigrants.  Apparently even the better-educated ones are not reaping real gains from (supposedly) skill-enhancing technical change:

The earnings and occupational task requirements of immigrants to Canada are analyzed. The growing education levels of immigrants in the 1990s have not led to a large improvement in earnings as one might expect if growing computerization and the resulting technological change was leading to a rising return to non-routine cognitive skills and a greater wage return to university education. Controlling for education, we find a pronounced cross-arrival cohort decline in earnings that coincided with cross-cohort declines in cognitive occupational task requirements and cross-cohort increases in manual occupational task requirements. The immigrant earnings outcomes had only a small effect on overall Canadian earnings inequality.

Immigrants of course are rarely labor market insiders, so, when structural change is occurring, they step into the new world of labor markets before the natives do.  You will find non-gated versions of the paper here.
