25/5/18: The Wondrous World of Cryptos Fraud: Profitable and Growing


One of the key promises of cryptocurrencies to their 'users'/'investors'/'gamblers' has been that of security of data stored on cryptos-backed blockchains and crypto 'assets' held by their owners. Yet, scandal after scandal, the myth has been deflated by the news flows, with security breaches, theft and fraud hitting the cryptos markets with frequency and impact not seen in traditional investment venues and asset classes.

Research by the Anti-Phishing Working Group released on Thursday shows that criminal activities have resulted in a theft of some $1.2 billion in cryptocurrencies since the beginning of 2017  (https://www.reuters.com/article/us-crypto-currency-crime/about-1-2-billion-in-cryptocurrency-stolen-since-2017-cybercrime-group-idUSKCN1IP2LU). Which is a significant number, but most likely an under-estimate to the true extent of theft and excludes fraud, especially fraud relating to the notorious ICOs.

In January-April 2018, ICOs raised some $6.6 billion, marking a 65% increase on 4Q 2017 ($3.9 billion in ICOs funding). Based on WSJ report that surveyed 1,450 ICOs, roughly 20 percent of the new offers raise major red flags for scams, including “plagiarized investor documents, promises of guaranteed returns and missing or fake executive teams”. Again, this is just a part of an iceberg. Ca half of all ICOs projects had no actual service or product offer behind them. In other words, investors in more than half of all ICOs were backing nothing more than a technological white paper, absent even a rudimentary business plan.

While there have been a lot of discussion in recent months about the potential Ponzi-game nature of the cryptos markets, irrespective of where you stand on the issue, there are two questions every investor must ask before dipping into the cryptos waters:
  1. Do I, as an investor, really comprehend the risks, uncertainties, complexities, and ambiguities imbedded in product offers I am considering investing in? and
  2. Do I, as an investor, have meaningful avenues for monitoring, hedging and/or ameliorating the above risks, uncertainties, complexities, and ambiguities imbedded in product offers I am considering investing in?
Now, without any sense of irony, when it comes to cryptos and ICOs, for any, even the most-informed and seasoned investor, the answers to (1) and (2) are 'No'. Which means that cryptos and ICOs are not a form of investment, but a form of speculative gambling. Nothing wrong with playing some chips at an unregulated casino, of course. Feel free to do so at own risk.

Update: A new research report (https://cointelegraph.com/news/ethereum-classic-51-attack-would-cost-just-55-mln-result-in-1-bln-profit-research) estimates that "it could take just $55 mln to hack a major cryptocurrency network for $1bln profit", providing yet more evidence that a "successful 51% attacks to control hashpower" previously deemed "too expensive and would result in making the attacked currency worthless" is no longer 'too expensive' and can deliver signifcantly higher profit margins than mining. So much for 'secure decentralized un-hackable' assets, thus.

24/5/18: America, the Medici Cycle and the Corporate Powers in Politics


A recent paper by Luigi Zingales of the University of Chicago, titled "Towards a Political Theory of the Firm" (NBER Working Paper No. 23593, July 2017: http://www.nber.org/papers/w23593) deals with the issue of rent-seeking behavior by monopolistic firms through political influence. "Neoclassical theory assumes that firms have no power of fiat any different from ordinary market contracting, thus a fortiori no power to influence the rules of the game," writes Zingales. "In the real world, firms have such power. I argue that the more firms have market power, the more they have both the ability and the need to gain political power. Thus, market concentration can easily lead to a “Medici vicious circle,” where money is used to get political power and political power is used to make money."

In his opening to the paper, Zingales notes 2016 report by Global Justice Now showing that 69 of the world’s largest 100 economic entities are now corporations, not governments. Using "both corporation and government revenues for 2015, ten companies appear in the largest 30 entities in the world: Walmart (#9), State Grid Corporation of China (#15), China National Petroleum (#15), Sinopec Group (#16), Royal Dutch Shell (#18), Exxon Mobil (#21), Volkswagen (#22), Toyota Motor (#23), Apple (#25), and BP (#27). All ten of these companies had annual revenue in higher than the governments of Switzerland, Norway, and Russia in 2015. ...In some cases, these large corporations had private security forces that rivaled the best secret services, public relations offices that dwarfed a US presidential campaign headquarters, more lawyers than the US Justice Department, and enough money to capture (through campaign donations, lobbying, and even explicit bribes) a majority of the elected representatives. The only powers these large corporations missed were the power to wage war and the legal power of detaining people, although their political influence was sufficiently large that many would argue that, at least in certain settings, large corporations can exercise those powers by proxy."

Despite this reality, economic theory largely ignores the issue of political power of the firms despite the fact that throughout modern history, "the largest modern corporations facilitated a massive concentration of economic (and political) power in the hands of a few people, who are hardly accountable to anyone." And despite the well-established fact (including through the precedent of the U.S. sanctions), that "...many of those giants (like State Grid, China National Petroleum, and Sinopec) are overseen by a member of the Chinese Communist party." Worse, as Zinglaes notes, "In the United States, hostile takeovers of large corporations have (unfortunately) all but disappeared, and corporate board members are accountable to none. Rarely are they not reelected, and even when they do not get a plurality of votes, they are coopted back to the very same board (Committee on Capital Market Regulation, 2014). The primary way for board members to lose their jobs is to criticize the incumbent CEO (see the Bob Monks experience in Tyco described in Zingales, 2012). The only pressure on large US corporations from the marketplace is exercised by activist investors, who operate under strong political opposition and not always with the interest all shareholders in mind."

So Zingales argues "that the interaction of concentrated corporate power and politics it a threat to the functioning of the free market economy and to economic prosperity it can generate, and a threat to democracy as well." Which, of course, is simply consistent with existence of the set of market-linked trilemmas, such as The International Relations (Order) Trilemma that implies that in the presence of perfect capital mobility, the nation states can either pursue a democratic sovereign political set up or an objective of international stability/order, as well as. (see more on these here: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2786660).

Logically, thus, economics need to be asking the following questions, largely ignored in the neo-classical theory of the firm: "To what extent can the power firms have in the marketplace be transformed into political power? To what extent can the political power achieved by
firms be used to protect but also enhance the market power firms have?"

As Zingales notes correctly, "US economic patterns in the last few decades have seen a rise in the relative size of large companies," as also documented in a number of posts on this blog:
for example, the rise of monopolistic competition here:


monopsonistic power here:


effects on regulatory enforcement efficiency here:


effects on democratic institutions here:



As the result, Zinglaes calls "attention to the risk of a “Medici Vicious Circle.” The “signorias” of the Middle Ages—the city-states that were a common form of government in Italy from the 13th through the 16th centuries--were a takeover of a democratic institution (“communes)” by rich and powerful families who ran the city-states with their own commercial interests as main objective. The possibility and extent of this Medici Vicious Circle depend upon several non-market factors. I identify six of them: the main source of political power, the conditions of the media market, the independence of the prosecutorial and judiciary power, the campaign financing laws, and the dominant ideology. I describe when and how these factors play a role and how they should be incorporated in a broader “Political Theory” of the firm."

The driver for this 'Medici Circle' dynamic is market concentration or monopolistic competition. Product differentiation and market regulation can bestow onto a firm a degree of market power that translates into market concentration (rising and significant share of market activity captured by the firm). While in the environment of continued innovation, such competitive advantage generates only temporary abnormal profits, the degree of market power can be significant enough to provide the firm with substantial resources (profits) to engage in lobbying activities, corruption and other rent-seeking activities. There are also symmetric incentives for the firms to engage in rent seeking. As Zinglaes notes: "If the ability to influence the political power increases with economic power, so does the need to do so, because the greater the market power a firm has, the greater the fear of expropriation by the political power". This sounds strange, but it is quite intuitive: as a firm gains market power, it's prices rise above the marginal cost, yielding abnormal economic profits to the firm at the expense of consumers. The Governments can (and do) claim political mandate to limit these profits by taxing the market dominant firms' profits (either through regulation or direct taxation), thus expropriating part of the abnormal profits.

In simple terms, "Most firms are actively engaged in protecting their source of competitive advantage: through a mixture of innovation, lobbying, or both. As long as most of the effort is along the first dimension, there is little to be worried about. ...What is more problematic is when a lot of effort is put into lobbying. In other words, the problem here is not temporary market power. ...The fear is of what I call a “Medici vicious circle,” in which money is used to gain political power and political power is then used to make more money. ...In the case of medieval Italy, it turned Florence from one of the most industrialized and powerful cities in Europe to a marginal province of a foreign empire. At least the Medici period left some examples of great artistic beauty in Florence. I am not sure that market capitalism of the 21st century will be able to do the same."

Zingales relates the Medici circle concept to the modern day U.S. economy. "In the last two decades more than 75 percent of US industries experienced an increase in concentration levels, with the Herfindahl index increasing by more than 50 percent on average. During this time, the size of the average publicly listed company in the United States tripled in market capitalization: from $1.2 billion to $3.7 billion in 2016 dollars... This phenomenon is the result of two trends. On the one hand, the reduction in the rate of birth of new firms, which went from 14 percent in the late 1980s to less than 10 percent in 2014. On the other hand, a very high level of merger activity, which for many years in the last two decades exceeded $2 trillion in value per year... The market power enjoyed by larger firms is also reflected in the increasing difficulty that smaller firms have in competing in the marketplace: in 1980, only 20 percent of small publicly traded firms had negative earnings per share, in 2010, 60 percent did... Barkai (2016) ...finds that the decrease in labor share of value added is not due to an increase in the capital share (that is, the cost of capital times amount of capital divided by value added), but by an increase in the profits share (the residuals), which goes from 2 percent of GDP in 1984 to 16 percent in 2014. ...By separating the return to capital and profits, we can appreciate when profits come from (non-replicable) barriers to entry and competition, not from capital accumulation. Distinguishing between capital and share allows Barkai (2016) also to gain some insights on the cause of the decline in the labor share. If markups (the difference between the cost of a good and its selling price) are fixed, any change in relative prices or in technology that causes a decline in labor share must cause an equal increase in the capital share. If both labor and capital share dropped, then there must be a change in markups—that is, the pricing power firms to charge more than their cost."

And fresh from the presses today: "US IG Chart of the Day: Global M&A deal flow has doubled YTD for a total of $1.5 trillion of announced deals. US-only deals account for about 37% of the global total, for $555 billion of transactions."


While firms require market power to acquire political power, access to political power is required to protect abnormal profits arising from market power. Which, in a highly polarised society (aka, the U.S. system of politics dominated by two mainstream parties) can result in political representation concentrated in the hands of minorities (e.g. Trump Presidency, gained absent major corporate support), and in ineffectiveness of lobbying monitoring (As Zinglaes notes: "Even when it comes to lobbying, the actual amount spent by large U.S corporations is very small, at least as a fraction of their sales. For example, in 2014 Google (now Alphabet) had $80 billion in revenues and spent $16 million in lobbying".) Which is, of course, quite ironic, given that the ongoing Robert Mueller probe of the Trump campaign is focusing almost exclusively on the violations in the legal or declared channels of lobbying, instead of the indirect forms of political influencing.


I will quote Zingales' conclusion almost in full here, for it is a powerful reminder to us all that we live in a world where corporatism (integration of State and corporate powers) and monopolisation / concentration of the markets are two key features of our environment, not only in the economic sense, but in the political / democratic domains as well.

"In a famous speech in 1911, Nicholas Murray Butler, President of Columbia University, considered the practical advances made by large corporations in the late 19th and early 20th century and stated: 'I weigh my words, when I say that in my judgment the limited liability corporation is the greatest single discovery of modern times, whether you judge it by its social, by its ethical, by its industrial or, in the long run, ...by its political, effects.' Butler was right, but this discovery of the modern corporate form – like all discoveries – can be used to both to foster progress or to oppress. The size of many corporations exceeds the modern state. As such, they run the risk of transforming small- and even medium-sized states into modern versions of banana republics, while posing economic and political risks even for the large high-income economies. To fight these risks, several political tools might be put into use: increases in transparency of corporate activities; improvements in corporate democracy; better rules against revolving doors and more attention to the risk of capture of scientists and economists by corporate interests; more aggressive use of the antitrust authority; and attention to the functioning and the independence of the media market. Yet the single most important remedy may be broader public awareness."

The latter bit is still woefully lacking in the Fourth Rome of Washington DC, where the usual, tired, unrealistic narrative of American Exceptionalism reigns supreme, and where the U.S. flags at the 4th of July picnics are still confused for meaningful symbols of the U.S. meritocracy and the American Dream, the native entrepreneurialism and the social mobility. Wake up, folks, and smell the roses.

23/5/18: Contingent Workforce, Online Labour Markets and Monopsony Power


The promise of the contingent workforce and technological enablement of ‘shared economy’ is that today’s contingent workers and workers using own capital to supply services are free agents, at liberty to demand their own pay, work time, working conditions and employment terms in an open marketplace that creates no asymmetries between their employers and themselves. In economics terms, thus, the future of technologically-enabled contingent workforce is that of reduced monopsonisation.

Reminding the reader: monopsony, as defined in labour economics, is the market power of the employer over the employees. In the past, monopsonies primarily were associated with 'company towns' - highly concentrated labour markets dominated by a single employer. This notion seems to have gone away as transportation links between towns improved. In this context, increasing technological platforms penetration into the contingent / shared economies (e.g. creation of shared platforms like Uber and Lyft) should contribute to a reduction in monopsony power and the increase in the employee power.

Two recent papers: Azar, J A, I Marinescu, M I Steinbaum and B Taska (2018), “Concentration in US labor markets: Evidence from online vacancy data”, NBER Working paper w24395, and Dube, A, J Jacobs, S Naidu and S Suri (2018), “Monopsony in online labor markets”, NBER, Working paper 24416, dispute this proposition by finding empirical evidence to support the thesis that monopsony powers are actually increasing thanks to the technologically enabled contingent employment platforms.

Online labour markets are a natural testing ground for the proposition that technological transformation is capable of reducing monopsony power of employers, because they, in theory, offer a nearly-frictionless information and jobs flows between contractors and contractees, transparent information about pay and employment terms, and low cost of switching from one job to another.

The latter study mentioned above attempts to "rigorously estimate the degree of requester market power in a widely used online labour market – Amazon Mechanical Turk, or MTurk... the most popular online micro-task platform, allowing requesters (employers) to post jobs which workers can complete for."

The authors "provide evidence on labour market power by measuring how sensitive workers’ willingness to work is to the reward offered", by using the labour supply elasticity facing a firm (a standard measure of wage-setting (monopsony) power). "For example, if lowering wages by 10% leads to a 1% reduction in the workforce, this represents an elasticity of 0.1." To make their findings more robust, the authors use two methodologies for estimating labour supply elasticities:
1) Observational approach, which involves "data from a near-universe of tasks scraped from MTurk" to establish "how the offered reward affected the time it took to fill a particular task", and
2) Randomised experiments approach, uses "experimental variation, and analyse data from five previous experiments that randomised the wages of MTurk subjects. This randomised reward-setting provides ‘gold-standard’ evidence on market power, as we can see how MTurk workers responded to different wages."

The authors "empirically estimate both a ‘recruitment’ elasticity (comparable to what is recovered from the observational data) where workers see a reward and associated task as part of their normal browsing for jobs, and a ‘retention’ elasticity where workers, having already accepted a task, are given an opportunity to perform additional work for a randomised bonus payment."

The findings from both approaches are strikingly similar. Both "provide a remarkably consistent estimate of the labour supply elasticity facing MTurk requesters. As shown in Figure 2, the precision-weighted average experimental requester’s labour supply elasticity is 0.13 – this means that if a requester paid a 10% lower reward, they’d only lose around 1% of workers willing to perform the task. This suggests a very high degree of market power. The experimental estimates are quite close to those produced using the machine-learning based approach using observational data, which also suggest around 1% reduction in the willing workforce from a 10% lower wage."


To put these findings into perspective, "if requesters are fully exploiting their market power, our evidence implies that they are paying workers less than 20% of the value added. This suggests that much of the surplus created by this online labour market platform is captured by employers... [the authors] find a highly robust and surprisingly high degree of market power even in this large and diverse spot labour market."

In evolutionary terms, "MTurk workers and their advocates have long noted the asymmetry in market structure among themselves. Both efficiency and equality concerns have led to the rise of competing, ‘worker-friendly’ platforms..., and mechanisms for sharing information about good and bad requesters... Scientific funders such as Russell Sage have instituted minimum wages for crowd-sourced work. Our results suggest that these sentiments and policies may have an economic justification. ...Moreover, the hope that information technology will necessarily reduce search frictions and monopsony power in the labour market may be misplaced."

My take: the evidence on monopsony power in web-based contingent workforce platforms dovetails naturally into the evidence of monopolisation of the modern economies. Technological progress, that held the promise of freeing human capital from strict contractual limits on its returns, while delivering greater scope for technology-aided entrepreneurship and innovation, as well as the promise of the contingent workforce environment empowering greater returns to skills and labour are proving to be the exact opposites of what is being delivered by the new technologies which appear to be aiding greater transfer of power to technological, financial and even physical capital.

The 'free to work' nirvana ain't coming folks.

23/5/18: American Exceptionalism, Liberty and... Amazon


"And the star-spangled banner in triumph shall wave
O'er the land of the free and the home of the brave!"

The premise of the American Exceptionalism rests on the hypothesis of the State based on the principles of liberty.

Enter Amazon, a corporation ever hungry for revenues, and the State, a corporation ever hungry for power and control. Per reports (https://www.aclunc.org/blog/amazon-teams-law-enforcement-deploy-dangerous-new-face-recognition-technology), Amazon "has developed a powerful and dangerous new facial recognition system and is actively helping governments deploy it. Amazon calls the service “Rekognition."

As ACLU notes (emphasis is mine): "Marketing materials and documents obtained by ACLU affiliates in three states reveal a product that can be readily used to violate civil liberties and civil rights. Powered by artificial intelligence, Rekognition can identify, track, and analyze people in real time and recognize up to 100 people in a single image. It can quickly scan information it collects against databases featuring tens of millions of faces, according to Amazon... Among other features, the company’s materials describe “person tracking” as an “easy and accurate” way to investigate and monitor people."

As I noted elsewhere on this blog, the real threat to the American liberal democracy comes not from external challenges, attacks and shocks, but from the internal erosion of the liberal democratic institutions, followed by the decline of public trust in and engagement with these institutions. The enemy of America is within, and companies like Amazon are facilitating the destruction of the American liberty, aiding and abetting the unscrupulous and power-hungry governments, local, state and beyond.

22/5/18: Poor Showing by the U.S. Cities


Mercer 2018 Quality of Living rankings are out: https://mobilityexchange.mercer.com/Portals/0/Content/Rankings/rankings/qol2018i321456/index.html. Summary of key results:


  • Top 25:

  • Not a single U.S. city makes it into top 25.
  • Highest-ranked U.S. city, San Francisco, ranks 30th in the world, Boston and Honolulu - second and third highest ranked U.S. cities are in 35th and 36th places.
  • Canada dominates North American rankings with 5 cities in top 35 against U.S. two cities.
  • Only one North American city, Vancouver, makes it in top 10 globally.
  • Switzerland and Germany (3 cities each) dominate top 10 rankings.
  • Dublin ranks 34th in the world and London 41st, competitive relative to the U.S. cities, and against key peer European cities.


Quality of urban life is a key determinant of economic development, competitiveness and growth potential in the advanced economies. From this perspective, U.S. cities are lagging behind their global counterparts due to low value for money in quality of housing, poor transportation and connectivity systems, poor public safety, underinvestment in social and public amenities, and lower quality of schools. Controlling for private education and healthcare (benefits of which are highly concentrated at the top of income distributions), the U.S. cities competitiveness would be even less impressive than the above rankings suggest.

21/5/18: Truth Decay and Fake News: Four Links


Some useful links on recent research  concerning the relationship between empirical/factual evidence, newsflows and policy discourse in the West:




21/5/18: Italian Sovereign Risks Are Blowing Up


As I noted in my comment to ECR / Euromoney and in my article for Sunday Business Post (see links here: http://trueeconomics.blogspot.com/2018/05/21518-risk-experts-take-flight-over.html and http://trueeconomics.blogspot.com/2018/05/21528-trouble-is-brewing-in-euro.html), the ongoing process of Government formation in Italy represents a fallout from the substantial VUCA events arising from the recent elections, and as such warrants a significant (albeit delayed) repricing of country sovereign risks. This process is now underway:

Source: Holger Zschaepitz @Schuldensuehner

Per chart above, Italy's 10 year bonds risk premium over Germany jumped to 181 bps on markets concerns with respect to fiscal dynamics implied by the new Government formation. This, however, is just a minor side show compared to the VUCA environment created by the broader dynamics of political populism and opportunism. And in this respect, Italy is just another European country exposed to these risks. In fact, as the latest data from the Timbro's Authoritarian Populism Index, Europe-wide, political populism is on the rise:

19/5/18: Leverage risk in investment markets is now systemic


Net margin debt is a measure of leverage investors carry in their markets exposures, or, put differently, the level of debt accumulated on margin accounts. Back at the end of March 2018, the level of margin debt in the U.S. stock markets stood at just under $645.2 billion, second highest on record after January 2018 when the total margin debt hit an all-time-high of $665.7 billion, prompting FINRA to issue a warning about the unsustainable levels of debt held by investors.

Here are the levels of gross margin debt:

Source: https://wolfstreet.com/2018/04/23/an-orderly-unwind-of-stock-market-leverage/.

And here is the net margin debt as a ratio to the markets valuation - a more direct measure of leverage, via Goldman Sachs research note:
Which is even more telling than the absolute gross levels of margin debt in the previous chart.

Per latest FINRA statistics (http://www.finra.org/investors/margin-statistics), as of the end of April 2018, debit balances in margin accounts rose to $652.3 billion, beating March levels

And things are even worse when we add leveraged ETFs to the total margin debt:

In simple terms, we are at systemic levels of risk relating to leverage in the equity markets.

19/5/18: The Scary Inefficiency & Environmental Costs of Bitcoin


Bitcoin is just one of the cryptocurrencies, albeit the dominant one by market capitalisation and mining assets deployment. The cryptocurrency is best known for volatility of its exchange rate to key fiat currencies and other commodities, but the more interesting aspect of the Bitcoin (and other cryptos) is their hunger for energy. Cryptos are based on blockchain technologies that promise a range of benefits (majority unverified or untested or both), amongst which the high degree of security and peer-to-peer data registry, both of which are supported by the mining processes that effectively require deployment of  a vast amount of hash/algorithmic calculations in order to create data storage units, or blocks. In a sense, energy (electricity) is the main input into creation of blockchain records of transactions.

As the result, it is important to understand Bitcoin (and other cryptos) energy efficiency and utilisation, from three perspectives:
1) Direct efficiency - value added by the use of energy in mining Bitcoin per unit of BTC and unit of information recorded on a blockchain;
2) Economic efficiency or opportunity cost of using the energy expended on mining; and
3) Environmental efficiency - the environmental impact of energy used.

To-date, estimating the total demand for electricity arising from Bitcoin mining (let alone from mining of other cryptos) has been a huge challenge, primarily because Bitcoin miners are too often located in secretive jurisdiction, do not report any data about their operations and, quite often, can be highly atomistic. Although Bitcoin mining is a concentrated activity - with a small number of mega-miners and mining pools dominating the market - there is still a cottage industry of amateur and smaller scale miners sprinkled around the globe.

Thus, to-date, we have only very scant understanding of just how much of the scarce resource (energy) does the new industry of cryptos mining consume.

A new paper, published in a peer-reviewed journal, Joule, which is a reputable academic journal, titled "Bitcoin's Growing Energy Problem" and authored by Alex de Viries (Experience Center of PwC, Amsterdam, the Netherlands) attempts exactly this. The paper is the first in the literature to be peer-reviewed and uses a new methodology to discern trends in Bitcoin's electric energy consumption. The paper does not cover other cryptos, so its conclusions need to be scaled to estimate the entire impact of cryptocurrencies energy use.

The findings of de Viries are striking. He estimates the current Bitcoin usage of energy at 2.55 gigawatts, close to that of Ireland (3.1GW), approaching 7.67GW that "could already be reached in 2018", comparable to Austria (8.2GW). When reached, this will amount to 0.5% of the total world electricity consumption.

Per 'efficiency of blockchain', a single transaction on Bitcoin network uses as much electricity as an average household in the Netherlands uses in a month. Which is, put frankly, mad, wasteful and utterly unrealistic as far as transactions costs go for the network.

Per de Viries: "As per mid-March 2018, about 26 quintillion hashing operations are performed every second and non-stop by the Bitcoin network (Figure 1). At the same time, the Bitcoin network is only processing 2–3 transactions per second (around 200,000 transactions per day). This means that the ratio of hash calculations to processed transactions is 8.7 quintillion to 1 at best. The primary fuel for each of these calculations is electricity."


The key to the above numbers is that they vastly underestimate the true costs of Bitcoin and other cryptos to the global economy. The paper focuses solely on energy used on mining. However, other activities that sustain Bitcoin and blockchains are also energy-intensive, including trading in coins/tokens, storage of information blocks, etc. Worse, mining and processing / servicing of the networks required use of constant electricity supply, which means that the energy mix that goes to sustain cryptocurrencies operations is the worst from environmental quality perspective and must rely on heavy use of fossil fuels in the top up range of electricity demand spectrum. The environmental costs of Bitcoin and cryptos is staggering.

Scaling up Bitcoin figures from de Viries; paper to include other major cryptocurrencies would require factoring in the BTC's share of the total crypto markets by energy use. A proxy (an imperfect one) for this is BTC's total share of the cryptocurrencies publicly traded markets which stood at around 37.3% as of May 16, 2018. Assuming this proxy holds for mining and servicing costs, total demand for electricity from the cryptocurrencies and blockchain use around the world is more than 2.55GW/0.37 or more than 6.9GW, with de Viries' model implying that by year end, the system of cryptocurrencies can be burning through a staggering 1.35% of total electricity supply around the world.

The problem with the key cryptocurrencies proposition is that the system of blockchain-based public networks can deliver lower cost, higher efficiency alternatives to current records creation and storage. This proposition simply does not hold in the current energy demand environment.

18/5/18: Euro area current accounts 1980-2017


What happened to the Euro area current accounts since the introduction of the Euro?

Periodically, I update my charts on the Euro effects on the external balances of the EA-12, the original economies of the Euro area. Here are the updates:

Considering first cumulated current account balances over 1980-2017 period, the chart below aggregates the EA12 into two sub-groups:

  • The 'periphery' defined as a group composed of Italy, Greece, Spain and Portugal
  • The 'core' group composed of the remaining EA12 countries

The chart shows several interesting facts
  1. Current account deficits in the 'peripheral' states predate the introduction of the Euro
  2. Since the introduction of the Euro through 2013 there was a consistent increase in the current account deficits amongst the 'periphery' states, with acceleration in deficits staring exactly at the point of the introduction of the Euro
  3. Current account deficits in the Euro area 'peripheral' states were rapidly accelerating into 2009
  4. Since 2014, current account deficits in the 'peripheral' states have been drawn down, at a moderate rate, as consistent with the internal deleveraging of these economies
  5. Meanwhile, the introduction of the Euro accelerated accumulation of current account surpluses within the 'core' group of EA12
  6. The rate of current account surpluses acceleration increased dramatically around 2004 and then again starting with 2009
In terms of external balances, the creation of the Euro area clearly resulted in compounding pre-Euro era existent structural imbalances in the EA12 economies.

Meanwhile, there is no discernible impact of the Euro on supporting growth in trade within the Euro area (here, we use changing countries composition of the Eurozone):

  As per above chart:
  • From 2000 and prior to 2014, Eurozone performance in terms of growth rates in exports of goods and services largely underperformed other advanced economies (ex-G7) and was in line with G7 performance
  • Before 2000, Eurozone was broadly in line with both the G7 and other advanced economies in terms of growth rates in exports of goods and services
  • Lastly, starting with 2014, the Euro area has been outperforming both the G7 and other advanced economies in terms of growth in exports of goods and services - a development that is more consistent with the fallout from the twin Global Financial Crisis (2007-2009) and the Euro Area Sovereign Debt Crisis (2011-2013), as the process of internal devaluation forced a number of Eurozone countries into more aggressive exporting
On the net, there remains no current account-linked evidence to support an argument that the creation of the Euro has been a net positive for the Eurozone member states in terms of improving their external balances and exports flows. On the other hand, there is little evidence that the Euro has hindered trade flows growth rates, whilst there is strong evidence to claim that the Euro has exacerbated current account imbalances between the 'core' and the 'periphery' states.
