@@MoneyMacro I think it is a flaw to assume that wealth distribution in autocratic countries is similar to democratic countries. A country 1000 people earning 100k$ per annum will cast much much more light than an impoverished country with 10 big shots earning 10M$ per annum even though the wealth is the same. If we look solely based on light emitted it might look like the first country is richer even though the second country is clearly equally rich in terms of money.

[@JohnnyLynnLee]

There is a MAJOR flaw in this paper. MOST countries that grow the fastest today are not Western Style Democracies and would be classified as "authoritarians". China, Vietnam, India, even Malaysia and Indonesia would be classified like that. Second, the MAJORITY of he poor countries of the world are to some extent authoritarian, and poor low and middle income countries tend to grow more than high income countries, where the vast majority of the MINORITY of countries that are Western Style democracies on our planet are. Simply because, contrary to what most Westerners think, the MAJORITY of planet Earth is made up by countries that would be considered "non-democratic". When it comes to low and middle income countries, where most likely you'll find a fast growing economy, that percentage is even higher. Which brings the problem of how those countries where determined to be "dictatorships" in the first place as well. In other words, most countries that grow fast would be classified as "dictatorships" (whether it being true or not). And that not because dictatorships are particularly good at making the economy grow (since most authoritarian countries are poor and people don't give a flying s** about them unless they are growing and defying the hegemony of the West) but simply because, again, it needs to be stressed again, MOST countries on planet Earth would be classified as authoritarians. Hence, in simple terms, if we will se a poor country becoming a rich country MOST LIKELY it will be a country classified that way. So the paper ASSUMES that "authoritarian countries" lie because they grow more when in fact countries that grow more in its vast majority are even as authoritarian or, at least, not mature democracies. OF COURSE the mature democracies will grow less. They are the richest countries on Earth.

The perverse incentive doesn't just apply to vacancy tax.

[@fernrfernandez]

Couple of issues with this study. First, the relationship with night light and GDP has been shown to depend on the level of urbanization. For example, study by Xaquín S.Pérez-Sindín et al. (2021) found that the relationship between satellite measured night light and GDP was strongest for urban areas (coefficient of 0.71 with an R2 of 0.5 for 500K centers vs.0.57 and an R2 of 0.32 for areas with 20-50K). Although having a large population, China is still less urbanized than the US and most Western European countries. Urbanization in China is ~61% vs. 82% in the US, with the difference being much larger during the 1990 - 2010 period. Additionally, Martinez assumes that the relationship between night light and GDP is linear. There's no reason to assume this as you might expect that increased GDP in highly developed countries might be near a saturation point; at some point this relationship will break down as economic growth is less tied to population growth and increased light generation (just an aside, health expenditure as a fraction of GPD in the US is 19% and has been a major contributor to US GDP growth. How is that tied to light generation?). Further, the R2 values are generally low (~0.3), indicating that there are a host of other factors far greater than night light that account for changes in GDP. Again, linear regression with values this low can't be used to conclude something as specific as China lying about its GDP numbers. Finally, the use of the "Freedom Index" is a little dubious. It seems unlikely that something as simplistic and ideological as a "Freedom Index" will capture any nuance in something as complex as a modern government. Correlation is not causation. In complex systems (especially anything as complex as economies and government) one will always find an endless number of variables that are weakly correlated. However, explaining how these variables relate mechanistically and causally is the hard part, which Martinez fails to do. When coupled with the low R2 values and low correlation there really isn't anything specific one can say about how governments lie about GDP measures. If this was a paper in a prestigious science journal it would have been rejected, not because its methods are wrong, but rather because its conclusion cannot be justified on the basis of the results and analyses presented. The only thing we can say with certainty is that there is a relationship between night light and GDP (with plenty of unexplained variance) and lots of variability between countries, regardless of whether we subjectively classify them as free or not.

[@kamilo4989]

Nice counter-comment. Thanks.

[@StevenBerg123]

thanks for the counter argument, very thorough. but isn't an R2 of 0.3 quite good for a social science?

[@jeffsims5407]

Growth in urbanization in China has been dramatic over this period, from 23% in 1990 to close to 64% in 2020, compared with 75%v to 82% in the US. Given what you say above, shouldn't we expect the night life growth to be even faster than GDP growth in China over the same period, rather than less?

[@fernrfernandez]

@@StevenBerg123 It may very well be a good value for a social science (I'm not in the field of social sciences) but if that is your analysis and value then you have to adjust your conclusions in accordance. You can't make such specific and extraordinary claims (seriously, claiming China is lying and that its economy is 60% less than claimed because it's an autocratic government is a pretty extraordinary and specific conclusion in the field of social sciences) without extraordinary data and more specific results. If someone claimed that the US economy is half of what the government claimed based on, for example, internet usage, nobody would take that seriously without additional data and analyses. Why should we hold any claim about China to a lower standard?

[@fernrfernandez]

Sure, but it also means that in the early stages of growth, when China's was a more rural society, light measures were a very poor indicator of economic growth. My point was that the level of light and GPD growth will not be linearly related since a country's level of urbanization will change over time, especially a country undergoing rapid development. So, for example, in the early period, when China was more rural and light levels were poorly correlated with GDP, the value would be weighed differently than values when the country was more urbanized. Hence, the relationship between light and GDP will not be linear across time and economic development as assumed by the study. Hence a low value with lots of unexplained variance doesn't really provide any mechanistic insight to reported GDP and light, especially since the definition of what is being compared (autocratic vs. democratic) is so vague and poorly defined. If you read the original study, Martinez also excluded a lot of autocratic countries that don't fit the trend because he claims they don't have any incentive to lie about GDP (mostly West African countries that receive aid and are friendly to Western interests). Why do this if you think autocratic governance is the major motivator for exaggerating GDP numbers. Clearly, things are way more complex than this.

[@alexf7951]

Another reason (in addition to the one I posted on air quality) for China's night lights not growing as fast as gdp could be that a lot of Chinas economic activity was building "Ghost Cities" and properties that were not inhabited, but instead held as a second home. These would not generate as much light, as only infrastructure surrounding the uninhabited skyscrapers would be lit.

[@matiasfpm]

Ah, yes, the infamous "styrofoam buildings"...

[@noahof-stuff9151]

They can also be useful as a tax write off as they are guaranteed to produce negative returns.

[@AlessandroRodriguez]

That right, but also can be worse, the ghost cities can qualify as wasted money, second home for vacation or work can be an asset, but those uses aren't realized in China, compounding the fact that many of those house are leases, that in 70 years will be lost money anyways

[@daniell1483]

The problem there is that so many of these secondary homes are rotten tail projects, homes that have not started or completed its construction phase and the original mortgage is essentially stolen into China's Ponzi scheme. Many citizens are being asked to essentially pay a full second mortgage to resume construction, with many of these projects having serious problems, such as concrete of such poor quality that you can break it by hand, not reinforced with rebar, etc. It is not like say here in the US where when you buy a secondary home, you then have the actual home. In China, the "house" is more of a "promise to build a house with substandard construction."

I haven't read the paper, but one variable to look into is population density in cities. Most urban growth in China seems to be "vertical", that is in tall skyscarpers that will emit proportionally less light per unit area than a growth based on sub-urban sprawl.

[@laurencefraser]

That makes sense for residential and office space, but they're also rather less relevant than industrial and retail space when it comes to GDP. retail effectively has a limit to how far up you can go (due to the logistics of getting both products and customers in and out), and industrial just doesn't really compress like that unless you start doing rather noteworthy and exotic things. Or at least, such is my understanding.

[@robinsoncrusoeonmars8594]

Sounds logical, but look at the lights on any map of Manhattan, and they are the brightest. For me, to see how China has manipulated data for decades with reporting GDP of 6% one quarter, 6.1% the next, then 6.2% the next. No legitimate country would report numbers in such a steady manner. Look at the democratic countries and they are 4.0% one quarter, 2.5% the next, 3.2 the next. China has their municipalities report that growth to make their numbers stay the course and have steady growth for their "image", not reality. Soon reality will catch up with them. Can you imagine any legitimate country missing out on a GDP report? That's what China has done because they are slowing down and don't want to admit it or not until the CCP party is over.

[@daniellejajko6204]

​@@robinsoncrusoeonmars8594 I think you're not quite familiar with the usual grography of chinese cities(spoiler it's totally different from Manhatta) For starters, Manhattan is extremely small and has a population density of over 72,000 people, no city in mainland China is that dense; it has been fully occupied for over 100 years, the only way to buil new stuff is by tearing old stuff down, theres barely a centimeter of undevelopped land in Manhattan. For contrast, cities in china have enormous land area, also being the center of administration of dozens of villages and smaller towns, so the population density is always relatively low; this one might sound a bit astonishing to you if youre from the US, but the average residential building in China is still taller than most buildings in Manhattan(because most of it was built a century ago, when there was no better technology. Also contrary to the popular belief, appartaments in mainland China are actually quite spacious, they only got a bad reputation because of Hong Kong and Macau); if you look on google maps you'll notice that in general urban areas in China are covered by HUGE parks, sometimes built right in the downtown areas, which is probably why it's not as bright as you'd expect. Also, Manhattan has a per capita of over 100,000USD, theres no reason to compare it to anywhere in China anyway.

China also has vertical residential facilities, but so do other countries. Since the more vertical, the higher the population density, so this can be verified through population density. According to that, the population density of India is higher than that of China. Many cities, such as Delhi in India, New York in the United States, Shanghai in Egypt, and Seoul in South Korea, have higher population densities than China. Well, yeah. Houses usually turn off the lights for sleep at night. Right? If so, the facilities that shine even at night are probably factories. But factories usually don't build high. The reason is.... The reason has been explained by many others. lol Then, China's GDP statistics should not be different from other countries.

[@abd5596]

There is one concern with nightlight data that you could mention : saturation. It doesn't mean that the calculation is wrong or anything like that, but rather than a straight line it's likely that the relationship between nightlight growth and GDP growth is concave in GDP (when GDP becomes larger, light intensity is more saturated so it grows slower for the same growth rate of the economy). So my only concern with the paper is that the relationship is overstated because Chinese economic growth is concentrated in rich areas where saturation is more of a thing. It would be cool to check the relationship for different provinces in China as a robustness check if you have the data !

[@JohnnyLynnLee]

No he is NOT. There is a MAJOR flaw in this paper. MOST countries that grow the fastest today are not Western Style Democracies and would be classified as "authoritarians". China, Vietnam, India, even Malaysia and Indonesia would be classified like that. Second, the MAJORITY of he poor countries of the world are to some extent authoritarian, and poor low and middle income countries tend to grow more than high income countries, where the vast majority of the MINORITY of countries that are Western Style democracies on our planet are. Simply because, contrary to what most Westerners think, the MAJORITY of planet Earth is made up by countries that would be considered "non-democratic". When it comes to low and middle income countries, where most likely you'll find a fast growing economy, that percentage is even higher. Which brings the problem of how those countries where determined to be "dictatorships" in the first place as well. In other words, most countries that grow fast would be classified as "dictatorships" (whether it being true or not). And that not because dictatorships are particularly good at making the economy grow (since most authoritarian countries are poor and people don't give a flying s** about them unless they are growing and defying the hegemony of the West) but simply because, again, it needs to be stressed again, MOST countries on planet Earth would be classified as authoritarians. Hence, in simple terms, if we will se a poor country becoming a rich country MOST LIKELY it will be a country classified that way. So the paper ASSUMES that "authoritarian countries" lie because they grow more when in fact countries that grow more in its vast majority are even as authoritarian or, at least, not mature democracies. OF COURSE the mature democracies will grow less. They are the richest countries on Earth.

Light surely also depends on things like population density and wealth disparity. The US typically has fairly spread out suburbs compared to the high-rise flats seen in China's cities. Surely this means one model for light intensity can't just be flatly applied to the other country and extrapolated from.

[@o-654]

Yeah overall this model just seems too simplistic. A rough estimate is fine, but to present the calculations as anything concrete is a bit irresponsible since it misses out on way too many factors like population density/concentrations, industries involved, how high-rises affect perceived luminosity at night, and not to mention the sample size used in the original study only extends until 2008.

And you are right I think it might be due to there are taller buildings which covers up individual light useage There are several possible other reasons I come up with my friends: 1. Chinese people stay up less at night because of culture of longevity than westerners. Westerners can stay up all night partying. Chinese people value sleep cycle more. Although, yes there are many Chinese people who still stay up late playing majiang or clubing but few. 2. electricity is not cheap. 3. retailing and face-to-face buisnesses are less and less popular because the digitalization and e-commerce, most people can stay at home not going out and live a life. So retailers which emit light is less.

[@jg5737]

While this model is very rough, it makes sense. This is especially so given that China has had the largest transfer of population from rural areas to urban areas in history over the past 2 decades. They should have very intense increases of light at night in and around their urban areas, and if they don't then something is not right. If even the Chinese Premier looks at power consumption levels rather than official economic data to make his judgement on economic growth, then the theory spoken of in this video makes even more sense.

The Chinese centralized state already does approximations of energy consumption + emissions + trade balances to adjust the "official regional report" down because the central government wants to know the true growth numbers for their 5 year plans. The regional governments caught on over time and adjusted these other numbers in accordance with their fake growth. However light pollution is a new metric that isn't used so that shows the true growth. However now that this paper has been published I'm sure the central government will use it to adjust local figures down which will result in corrupt local officials doing stupid stuff like forcing new buildings and companies to install brighter lights to fake more growth or something like that. There was the scandal of fake solar and wind installations in shenzhen city a couple of years ago as well.

In order to reaffirm the data, maybe a few more data points should be collected: -infrared radition into space (= Energy consumption) -foreign trade -money spent by Chinese tourists abroad (via credit card and ATM withdrawl) -car traffic -cargo traffic on chinese rivers, railroads and freeways The problem that I see, is that a direct correlation between economic power and light emitted is probably very difficult. The light-emission curve is probably very steep at the beginning when people start to afford electricity, but once people's need for light has been satisfied, I doubt that further GDP-groth will lead to substainial further light emission groth.

As long as people in China FEEL some improvements, then the real economic numbers don't matter all that much and can easily be justified. It doesn't take much to dupe the world when the world takes a country at face value. GDP is not something you can find with evidence, you can only discern it by parsing through the data of an entire country which only said country's government can accomplish.

China's GDP is certainly smaller than what they claim it to be, however if it was 60% smaller it would have massive implications because you can lie about statistics; but this true to a certain extent due to these "numbers" exposing an economy that it's not true at all. In my country, Spain, if the offical gdp fake was around what France has it wouldn't make sense because the median annual wage is around 25k while France is closer to 35k (maybe a bit more); it is also important to take into account that these 2 countries have different ammount of inhabitants; but still, my point is that you can't present a flawed number if that precise number is showing an opposite reality or very different atleast... and as far as I'm concerned China GINI is 38,2 therefore gdp is moderately distributed and not kept by a small percentage of the population

This is because GNI per capita is the threshold at which regimes may claim financial aid from the GNI, so the incentive for low-income developing countries would be to fudge the statistics for as long as possible to maintain aid - another indicator of regime untrustworthiness. To his credit, the paper's author did rigourously collate and analyse this data, and shows in Table C4 the year at which countries became ineligible for IDA assistance. China became ineligible in 2000, 4 years behind of Indonesia (dictatorship until 1999) but 10 years ahead of democratic India and 13 years ahead of Pakistan (dictatorship in 1999 gradually democratised in the 00's and 10's)

Thanks for sharing this interesing research paper! However, I have some disagreements.... 1. Until Xi took office in 2012, Beijing took more of a restrained foreign policy approach. 韬光养晦 - is what this approach is called, which was intended to keep China out of the Thucydides trap for as long as possible. China benefits from being underestimated, so they'd be less harsh on international obligations and wouldn't be targeted by U.S. sanctions. Also, instead of manipulating the numbers, they could just talk about GDP adjusted for purchasing power. 2. Economic performance is linked to an innumerable number of third-party variables. Variables that are collected by different institutions at home and abroad. Just as an example, with a GDP of 6 trillion USD China would have a foreign trade GDP ratio of 100% (this figure is also issued by the contracting parties, so it is not in Beijing's making), four times as much as the USA. The argument can be extended at will - a factor of 3 is therefore quite unthinkable. 3. and this is probably the most important point: the highly developed and democratic OECD countries have a completely different economic basis than the autocratic developing countries. Everything from sectoral order to the progress of commodification can be a possible alternative explanation for light pollution growth or its absence. The absolute value, on the other hand, is no good either; for this, one only needs to look at the current world ranking, according to which Iran is three times as productive as Germany (similar number of population). Of course, the Chinese figures should still be viewed critically, but 40% of economic output sounds like Washingtons wishful thinking to me. In this extent, that would have already been followed up long ago. Nevertheless, thanks for the contribution!

@@f0rgetwasure105 No the government already overestimates the economy to account for those things, but mostly the estimates are roughly consistant with metrics such as electricity consumption or trade volume

[@oqoq7774]

You should keep in mind that of the factors that affects the amount of night light is the population, and in China, with its 1-child and 2-child policy, the population grew much slower than in other states, for example, than in the same India.

[@pointbite]

That's just more evidence the GDP numbers are fake.

[@StephenGillie]

That's exactly the point here - count the number of house lights. Peter Zeihan calls it the "checkbook map" because he's old and still uses checks to pay his utilities. But he's right in that every house light is someone who's paid their electricity bill. (Or paid their fuel bill for their generator. Or spent time on their house-powering stationary bicycle.) So if there are 20,000 house lights, but 30,000 households are counted, something is incorrect. Ironically, the CCP developed this metric for internal audits, and now it's being used for external audits of the CCP.

[@kevin9794]

I wish I had access to the paper, because there's a lot of factors that I'd love to read about, to know how they were accounted for: 1. Density- the USA is incredibly sprawl-y. For example, a huge percentage of land in the USA is devoted to single family homes, and I cannot imagine these look 100x dimmer than a towering residential building since the lower floors will be covered by the upper floors. But even focusing on single family homes though; they're huge in the USA, with huge driveways and lots of road-space in between. I've seen other countries build closer together, with less driveway space. I imagine brightness from space is a function of factors like window-size and the asphalt around a building the light can bounce off, which will be lower for denser countries. Moreover, countries with better rail and public transport will see less lights at night from trucks and trailers. 2. Authoritarianism & data-points- how is this calculated? I don't doubt this hypothesis is probably true for some countries, but in order to show a trend one needs a consistent measure of "authoritarianism" which sounds like it could be subjective. Moreover, is the sample size all countries? Wouldn't the omission of countries be a possibility for counter examples that would muddle the data and erase a clearly-visible trend? 3. Culture- Where I'm from we turn off the lights at night, and one thing that surprised me in the USA is just how laissez-faire it is with electricity. This is also a place that's quite thorough with public lighting, and I can only imagine it has at least partially to do with a cultural looming sense of disaster and distrust for one's neighbors. All streets have public lighting here, even the ones that are not that transited, the huge parking lots of supermarkets (you don't see those in China), etc. Can we assume that other nations will demand the same level of public illumination when they develop? I live in the USA now and have certainly grown more accustomed to "leaving the lights on", but not to the degree of other people here. I can imagine there's a whole generation or two in China who are still very mindful of energy conservation in spite of their increased purchasing power, which could show in residential areas, and if their perception of security is also different, why waste energy? I have to wonder also how points 1 & 3 above correlate with "authoritarianism". Ie, would an "authoritarian" country give a greater sense of security to people, thus reduce their desire for public lighting? Or perhaps state-affiliated energy/development companies simply set up less public lighting since consumer demands matter less? Are denser countries more likely to be "authoritarian" or vice versa? I don't doubt China's numbers are made-up to some degree, though speaking of China's case, a ballpark 3x difference in official vs real economy size sounds crazy, and the correlation between brightness and GDP sounds true but very variable from culture to culture, history to history, city to city.

[@Pasta_Pirate]

Same by itself this leaves too many questions I can believe theyd perhaps mess around with it, but him deciding to extrapolate from these numbers is also ill advised since the author certainly had a reason he didn't do so himself. Furthermore I completely agree with your points and wish that while making such a groundbreaking/clickbait claim to expand and find other references aka import/export data, resources, capital flows, standard of living, and various other components and tie that into this since extraordinary claims require extraordinary evidence and one paper (even a good paper) indicating something might be the case alone is at best a starting point.

[@vince14genius]

I agree with you on #2 and #3, but for #1 don't forget that there are many dense/transit-oriented democratic countries and sprawling/car-dependent authoritarian countries as well.

[@mma93067]

Exactly. I’d like to see the dataset and controls used for analysis. Have they accounted for cultural differences like asian families who have multiple generations in a single household vs nuclear families? Relative safety of the region? Suburban areas vs nightlife zones? There are a lot of controls required that i can’t take this at face value. At worst, this😊 is the perfect example of “correlation does not imply causation”

@@Pasta_Pirate It is very simple. You need to get the real GDP of China, and infer it by looking at the trade volume between China and other countries in the world. It should be the most accurate. Only commodities and trade can truly reflect the GDP of each country.

[@vkieuvongngam]

I was just talking to my husband about this that this is a huge claim. There are a few things: 1. If I'm an accountant and I want to know who lie on their tax return. I wouldn't just look at their Halloween props. To be fair, Halloween props may give a clue about their wealth but can only point you further to scrutinize the accounting book. A better way would be to actually look at the accounting book itself. For example, look at export number. I believe since China has been export-led economy, so it accounts for a big percentage of the economy. You'd be able to track export to other countries every year over time. You might not believe China's number, but you certainly can believe US or other Democratic country import-from-China number (since how else can you the source of truth for your GDP deflator curve). So the question is do we see anything fishy in those numbers; and if so, it will lead to other accounting investigations such as how the number will add up, etc. 2. a paper is published doesn't mean it's correct. It just means that the author satisfies the publication criteria. They may publish in order to invite other papers to refutes the claim or refine the methodology.

[@vkieuvongngam]

3. Another thing is if you look at the curve at 4.30 minute. There is one obvious outlier. What happens if you remove that one outlier at the bottom left? Would the two regression line be more parallel? I believe the author is questioned about this outlier every time he gives a talk.

[@Isometrix116]

I’m not sure the Halloween prop example is a good one. Unlike Halloween props, light and electricity usage is directly and irrefutably directly proportional to GDP. Meanwhile, Halloween props are not directly proportional because of the myriad of external factors that are more important to the Halloween props than just how much money they have. What matters here is that “directly proportional.” Because the proportionality is direct, you can actually use one to determine the other. Given, approximately, but you can still do it.

Usually just the kid's room and the main living room.

[@Anon282828]

An interesting discussion. A quick internet search brought up a 2013 article from the Kiel Institute for the World Economy (Kiel Working Paper No. 1888 | December 2013; 'Night Lights and Regional GDP'; Bickenbach et Al.) which concluded that: "The relationship between regional GDP and night lights proves to be unstable, not only where regional GDP data may be unreliable but also where such data are of high quality. This suggests that night lights tend to be a poor proxy of regional economic activity." The article uses some sophisticated-looking statistical analysis (which I have not gone through in detail), but in any case seems quite thorough. Interestingly, this work is not referenced or discussed in Martinez (2018). What do you think?

I worked for many years compiling national statistics and we would joke all the time about internal inconsistencies in China’s numbers. It is easy to simply report higher top-level GDP. However, to state the obvious, GDP is a combination of data from a variety or sources, and while China has gotten much better at ensuring alignment with the “correct” growth target, we now often see different issues where volatility and consistency seem too perfectly in balance. I don’t know many who would be surprised by the growing discrepancy between real and reported figures. Very sorry to hear about the Macrocat!

The Chinse economy has most likely already surpassed the USA at this point. Even if it is smaller than the US economy in the terms of dollars, I see no reason to doubt that it has the biggest economy in real terms (good produced, roads and houses built, etc.).
