I Stumbled Upon A Hidden Trove

When hunting around to find something interesting to read about bitcoin I came across this survey:
It was published on June 3, 2021 by Parthajit Kayal, Assistant Professor (Finance Area), Madras School of Economics and Purnima Rohilla, Madras School of Economics (MSE)
This article is a survey of published academic papers about bitcoin. You can download the 21 page article through the link. The list of cited articles is substantial, and most of these have not likely been read by your typical bitcoiner.
I really want @Undisciplined, a real economist, to read the whole thing, including all of the source material, and give us his opinion, but I resent when people give me homework, unsolicited, so I won’t push.

What You Might Find

Even if you’re not an economist, you might find something that draws your attention. For instance, in the section on Price Dynamics, I found this intriguing and questionable passage:
Using Economic Freedom Index, Viglione (2015) studies the role of governance and other related factors in determining the price of Bitcoin as measured by the willingness of users to pay a premium. This work exhibits that real interest rates, tax burden, and investment freedom across different countries is significant in determining Bitcoin prices. In contrast, inflation rates and monetary freedom across boundaries have no impact on Bitcoin prices.
Some of the arguments mentioned in the survey seem ridiculous, like this one:
Bitcoin may have a fixed supply but the digital currency market is not fixed overall. There are more than two thousand digital currencies available to date and new currencies are getting launched often."
Others are prescient, like this one, which seems to support small blockers before the war started:
An older study by Houy (2014) analyses the economics of Bitcoin transaction fees and finds that efficiency is enhanced by implementing transaction fee and limited block size in mining.
Here’s another passage that caught my eye:
As noted by Yermack (2015) and Ali et al. (2014), a fixed supply will lead to deflation which will, in turn, lead to high welfare destroying volatility. It will be a difficult task indeed to match the variation in demand. Ali et al. (2014) propose that a more flexible system is required to respond to varying demands. One way is to have an adjustable growth rate of currency supply and another is a decentralized voting mechanism. While some researchers predict a possibility of deflation, Lo and Wang (2014) throw light on a possible scenario of hyperinflation if the central bank chooses to oversupply currency. These possible scenarios of deflation and inflation are ruled out by Iwamura et al. (2014b) as they argue that fixed supply will only negatively impact the profitability of mining activity but not lead to a deflation-like situation.
I take issue with the assumption that deflation will automatically lead to “welfare destroying volatility.” or the idea of an adjustable growth rate of currency supply to achieve it.

Final Thoughts

I have barely scratched the surface. The survey and articles will provide plenty of rabbit holes for armchair amateur economists like me, and maybe even some professionals like @Undisciplined
Your wish is my command, but you should also have petitioned @SimpleStacker to take a looksie.

Cool, I'll take a look too.
reply
Great!

There is a lot here. I may try to take a deeper look at some of the individual sources and make a series of posts about it (article reviews). I'll try to pick ones that may be of interest to the broader bitcoin/SN community as a whole.
reply
I'm looking forward to reading what you produce.
reply
Me too. I'm just going to keep working through it and leaving my comments in this post.

I'm glad you guys are weighing in. When I was reading about "adjustable growth rate of currency supply" in the survey, I wonder if the underlying article got into tail emissions like @petertodd raised here
that caused so much debate?

Reading through the first cited paper (Aalborg et al. 2019), a couple of things come to mind immediately:
  1. Mainstream economists have a shockingly poor understanding of bubbles (not shocking to me anymore, but you would be shocked, Dear Reader).
  2. Mainstream economists don't realize that when they're doing econometric analysis it is at best an exercise in economic history.
The first point is relevant to the multiple concurring expert opinions that bitcoin is in a speculative bubble, back in 2015, just based on the amount of speculative investment. These people do not understand the role of entrepreneurship at all.
The second point means that economists are going to think the same factors drive Bitcoin trading volume in 2024 as in 2015.
I don't think these authors (or perhaps their reviewers) have much confidence in their methodology, because they avoid describing their findings as "causal" and opt for the safer language of "predicts". They deserve credit for having appropriate humility, but if they aren't making causal claims then I don't need to pick them apart.

Thanks for this. I was wondering as I was going through it whether it would make a difference if the survey was done from post 2021 papers. I'm sure this stuff is still being cranked out, but it would be tough to find them all in one place.
reply
It would make a huge difference. One thing to keep in mind is that there are significant lags in research. By the time a paper comes out the data could easily be several years out of date, as well as the approach and hypotheses.

Here's a passage from the introduction of the Ciaian and Rajcaniova (2016) paper.
Among the BitCoin features, which may facilitate its use as a currency, we have identified low transaction costs, high anonymity and privacy, learning spillover effects, infinite divisibility and no inflationary pressures.
Among the BitCoin features, which may impede its use as a currency include the absence of a legal tender attribute, difficulty to procure BitCoins, relatively high fixed costs of adoption, dependence on network externalities, absence of an institution enforcing dispute resolution, absence of BitCoin denominated credits, deflationary pressure, extremely high price volatility, and issues with cyber security.
I think that's a very fair set of factors, for 2016. Some of the impediments have improved tremendously in the past 8 years and they are all things that can improve (except for deflationary pressure, which is a fake impediment).
reply
being a virtual currency, BitCoin is more vulnerable to cyber-attacks than traditional currencies
ROFL!
That clearly came from someone with no clue about how either bitcoin or modern banking/finance work.
It's not a particularly important part of the paper, but it's really damn funny.
reply
This paper discusses the lack of bitcoin credit markets as one of the major obstacles to becoming a medium of exchange. In one sense, I agree with this, but the authors don't seem to understand that you can have functioning credit markets without fractional reserve banking.
Bitcoin credit markets would function exactly like credit markets were supposed to work on the gold standard (bitcoin just prevents the rampant cheating that occurred). A lender (mortgage provider or credit card company, for instance) would have to hold the bitcoin first and would then allow customers to spend it on condition of repaying them with interest. It's not that hard to understand, as it's how most normal people think the current finance system works.

This Viglione paper looks interesting, but it isn't about bitcoin, per se. The author is taking advantage of bitcoin's properties as a globally available asset, to study how different institutions affect pricing. Bitcoin is ideal for this because it has such low transactions costs (like transportation, for instance) that it should be able to move across borders very easily.
What's important to realize about this paper is that it's about the differences in bitcoin prices across countries (price premia), not about bitcoin's actual purchasing power.
So, inflation being found to be insignificant, doesn't mean that bitcoin doesn't appreciate with inflation. It means that bitcoin doesn't appreciate disproportionately to inflation: i.e. the price premium doesn't increase with inflation.
Here's a nice excerpt from the conclusion of the paper:
Standard finance theory would suggest inter-market price differences exist because of microstructure characteristics like trading volume and bid-ask spreads. These factors do explain part of the price differences, but there is a missing piece to the puzzle that seems to be explained by proxies to a variety of economic freedom measures that cause large enough frictions to limit arbitrage.
The "mystery" being investigate is why there are cross-border price differences in an asset like Bitcoin, when the naive expectation would be that arbitrage would quickly resolve those differences.

Something that I think the author as well as the cited authors are missing, and it's making the writing confusing, is that the price of bitcoin should be treated like an exchange rate.
They're talking about the supply side dynamics of bitcoin exchange rates, but seem to be confusing themselves by saying bitcoin has a precisely known supply. By that logic, gold and silver have almost perfectly known supplies, because we know how much is in the Earth/Solar System/Universe.
The supply of bitcoin, as it pertains to the exchange rates, is what the current holders are willing to exchange it for. That's much more complicated, since many of us simply will not exchange our bitcoin for dollars, while others are just day-trading, and everything in between.
reply
It would seem to render the analysis useless then, no? I wonder if there is a way to bring this to mainstream economist's attention. Maybe a co-authored paper from you and @SimpleStacker?
reply
I'm not a macro guy and I don't think he is either.
Edit: I'm not sure it renders the analysis useless, but it makes it unsurprising that they didn't identify any supply side drivers. They're thinking about bitcoin as something that is being produced for the sake of fiat profits.
reply
Yeah, not a macro guy either. I would like to write a paper on Bitcoin one day, but that may be a pipe dream given the amount of effort it takes to start a new research agenda.
As to the point on supply curves, I also wouldn't say it renders the paper useless, but it really depends on the papers' goals. Again, i'd have to take a deeper dive which I'm really looking forward to, just gotta find time.
Also, interesting tidbit, Coinbase's UI shows the depth chart of bitcoin, i.e. the current buy orders at each price level and the current sell orders at each price level. I use that to show a visualization of supply and demand in my intro to micro class.

No doubt that also has myriad problems, but at least it's the right concept.
Edit: It looks like this Brandvold paper uses exchange information from Mt. Gox to analyze price dynamics.
