Abstract This paper identifies and analyzes BitCoin features which may facilitate Bitcoin to become a global currency, as well as characteristics which may impede the use of BitCoin as a medium of exchange, a unit of account and a store of value, and compares BitCoin with standard currencies with respect to the main functions of money. Among all analyzed BitCoin features, the extreme price volatility stands out most clearly compared to standard currencies. In order to understand the reasons for such extreme price volatility, we attempt to identify drivers of BitCoin price formation and estimate their importance econometrically. We apply time-series analytical mechanisms to daily data for the 2009-2014 period. Our estimation results suggest that BitCoin attractiveness indicators are the strongest drivers of BitCoin price followed by market forces. In contrast, macro-financial developments do not determine BitCoin price in the long-run. Our findings suggest that as long as BitCoin price will be mainly driven by speculative investments, BitCoin will not be able to compete with standard currencies.

The most successful among them is BitCoin, both in terms of its impressive growth in the number of currency users and popularity by retailers. Since its introduction in 2009, BitCoin has been characterized also by a phenomenal increase in the number of transactions and market capitalization, which surpassed 5 billion US dollar in 2015 and since then has recorded further growth. In the public media and in scientific community there is ongoing a lively debate on wheather BitCoin can actually function as a substitute for standard currencies such as US dollar, Euro or Yen. There are two competing views in the literature on whether BitCoin fulfils the three criteria of a currency (a medium of exchange, a unit of account, and a store of value) (Mankiw 2007). One part of the literature argues that BitCoin does not behave as a real currency, but rather resembles speculative investments (e.g. Velde 2013; Hanley 2014; Yermack 2014; Williams 2014). Other line of research, stresses the positive aspects of BitCoin and perceives it as a global virtual currency with strong future potential (e.g. Plassaras 2013; Satran 2013; Luther and White 2014; Folkinshteyn, Lennon and Reilly 2015). Also from a legal point of view, there is no global agreement on the status of BitCoin, as there are no international laws regulating Bitcoin. Each country regards Bitcoin differently and regulations are constantly evolving. For example, the Internal Revenue Service in the US has assigned BitCoin as barter on the grounds of the market- orientated approach. Finland considers BitCoin as priced commodity. Germany has recognized it as private currency. Yet other EU Member States by and large are in the wait-and-see stage. On the other hand, institutions such as European Central Bank (ECB) and European Banking Authority (EBA) define BitCoin as virtual currency. In light of these and other open questions about BitCoin, in April 2015 the European Commission organized a Virtual Currencies Conference,2 where among others the potential and challenges of BitCoin to become a global currency were discussed. The Virtual Currencies Conference acknowledged the need for further research to better understand the socio-economic and monetary aspects of the virtual currency ecosystem. In order to shed light on these and related questions, the present paper attempts to identify and analyze BitCoin features which may facilitate Bitcoin to become a global currency, as well as characteristics which may impede the use of BitCoin as a medium of exchange, a unit of account, or a store of value. 2 http://ec.europa.eu/digital-agenda/en/news/blockchain-and-digital-currencies-workshop 2 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

  • The Origins of Velocity Functions
    The Origins of Velocity Functions Thomas M. Humphrey ike any practical, policy-oriented discipline, monetary economics em- ploys useful concepts long after their prototypes and originators are L forgotten. A case in point is the notion of a velocity function relating money’s rate of turnover to its independent determining variables. Most economists recognize Milton Friedman’s influential 1956 version of the function. Written v = Y/M = v(rb, re,1/PdP/dt, w, Y/P, u), it expresses in- come velocity as a function of bond interest rates, equity yields, expected inflation, wealth, real income, and a catch-all taste-and-technology variable that captures the impact of a myriad of influences on velocity, including degree of monetization, spread of banking, proliferation of money substitutes, devel- opment of cash management practices, confidence in the future stability of the economy and the like. Many also are aware of Irving Fisher’s 1911 transactions velocity func- tion, although few realize that it incorporates most of the same variables as Friedman’s.1 On velocity’s interest rate determinant, Fisher writes: “Each per- son regulates his turnover” to avoid “waste of interest” (1963, p. 152). When rates rise, cashholders “will avoid carrying too much” money thus prompting a rise in velocity. On expected inflation, he says: “When...depreciation is anticipated, there is a tendency among owners of money to spend it speedily . the result being to raise prices by increasing the velocity of circulation” (p. 263). And on real income: “The rich have a higher rate of turnover than the poor. They spend money faster, not only absolutely but relatively to the money they keep on hand.

Para Ricardo, la regulación del valor del dinero por su cantidad es un caso particular en el cual el ajuste del precio de mercado al precio natural requiere un largo periodo de tiempo. La determinación cuantitativa es completamente inadmisible, pero solo cuando el período de observación es más corto que el de ajuste.

  • Bitcoin: Technology, Economics and Business Ethics
    Bitcoin: Technology, Economics and Business Ethics By Azizah Aljohani A thesis submitted to the Faculty of Graduate and Postdoctoral Studies in partial fulfilment of the degree requirements of MASTER OF SCIENCE IN SYSTEM SCIENCE FACULTY OF ENGINEERING University of Ottawa Ottawa, Ontario, Canada August 2017 © Azizah Aljohani, Ottawa, Canada, 2017 KEYWORDS: Virtual currencies, cryptocurrencies, blockchain, Bitcoin, GARCH model ABSTRACT The rapid advancement in encryption and network computing gave birth to new tools and products that have influenced the local and global economy alike. One recent and notable example is the emergence of virtual currencies, also known as cryptocurrencies or digital currencies. Virtual currencies, such as Bitcoin, introduced a fundamental transformation that affected the way goods, services, and assets are exchanged. As a result of its distributed ledgers based on blockchain, cryptocurrencies not only offer some unique advantages to the economy, investors, and consumers, but also pose considerable risks to users and challenges for regulators when fitting the new technology into the old legal framework. This paper attempts to model the volatility of bitcoin using 5 variants of the GARCH model namely: GARCH(1,1), EGARCH(1,1) IGARCH(1,1) TGARCH(1,1) and GJR-GARCH(1,1). Once the best model is selected, an OLS regression was ran on the volatility series to measure the day of the week the effect. The results indicate that the TGARCH (1,1) model best fits the volatility price for the data. Moreover, Sunday appears as the most significant day in the week. A nontechnical discussion of several aspects and features of virtual currencies and a glimpse at what the future may hold for these decentralized currencies is also presented.

  • Cryptocurrency: the Economics of Money and Selected Policy Issues
    Cryptocurrency: The Economics of Money and Selected Policy Issues Updated April 9, 2020 Congressional Research Service https://crsreports.congress.gov R45427 SUMMARY R45427 Cryptocurrency: The Economics of Money and April 9, 2020 Selected Policy Issues David W. Perkins Cryptocurrencies are digital money in electronic payment systems that generally do not require Specialist in government backing or the involvement of an intermediary, such as a bank. Instead, users of the Macroeconomic Policy system validate payments using certain protocols. Since the 2008 invention of the first cryptocurrency, Bitcoin, cryptocurrencies have proliferated. In recent years, they experienced a rapid increase and subsequent decrease in value. One estimate found that, as of March 2020, there were more than 5,100 different cryptocurrencies worth about $231 billion. Given this rapid growth and volatility, cryptocurrencies have drawn the attention of the public and policymakers. A particularly notable feature of cryptocurrencies is their potential to act as an alternative form of money. Historically, money has either had intrinsic value or derived value from government decree. Using money electronically generally has involved using the private ledgers and systems of at least one trusted intermediary. Cryptocurrencies, by contrast, generally employ user agreement, a network of users, and cryptographic protocols to achieve valid transfers of value. Cryptocurrency users typically use a pseudonymous address to identify each other and a passcode or private key to make changes to a public ledger in order to transfer value between accounts. Other computers in the network validate these transfers. Through this use of blockchain technology, cryptocurrency systems protect their public ledgers of accounts against manipulation, so that users can only send cryptocurrency to which they have access, thus allowing users to make valid transfers without a centralized, trusted intermediary.

  • The Economic Limits of Bitcoin and the Blockchain∗†
    The Economic Limits of Bitcoin and the Blockchain∗† Eric Budish‡ June 5, 2018 Abstract The amount of computational power devoted to anonymous, decentralized blockchains such as Bitcoin’s must simultaneously satisfy two conditions in equilibrium: (1) a zero-profit condition among miners, who engage in a rent-seeking competition for the prize associated with adding the next block to the chain; and (2) an incentive compatibility condition on the system’s vulnerability to a “majority attack”, namely that the computational costs of such an attack must exceed the benefits. Together, these two equations imply that (3) the recurring, “flow”, payments to miners for running the blockchain must be large relative to the one-off, “stock”, benefits of attacking it. This is very expensive! The constraint is softer (i.e., stock versus stock) if both (i) the mining technology used to run the blockchain is both scarce and non-repurposable, and (ii) any majority attack is a “sabotage” in that it causes a collapse in the economic value of the blockchain; however, reliance on non-repurposable technology for security and vulnerability to sabotage each raise their own concerns, and point to specific collapse scenarios. In particular, the model suggests that Bitcoin would be majority attacked if it became sufficiently economically important — e.g., if it became a “store of value” akin to gold — which suggests that there are intrinsic economic limits to how economically important it can become in the first place. ∗Project start date: Feb 18, 2018. First public draft: May 3, 2018. For the record, the first large-stakes majority attack of a well-known cryptocurrency, the $18M attack on Bitcoin Gold, occurred a few weeks later in mid-May 2018 (Wilmoth, 2018; Wong, 2018).

Modern Monetary Theory: A Marxist Critique Abstract Compiled from a series of blog posts which can be found at "The Next Recession." Modern monetary theory (MMT) has become flavor of the time among many leftist economic views in recent years. MMT has some traction in the left as it appears to offer theoretical support for policies of fiscal spending funded yb central bank money and running up budget deficits and public debt without earf of crises – and thus backing policies of government spending on infrastructure projects, job creation and industry in direct contrast to neoliberal mainstream policies of austerity and minimal government intervention. Here I will offer my view on the worth of MMT and its policy implications for the labor movement. First, I’ll try and give broad outline to bring out the similarities and difference with Marx’s monetary theory.

As the monetarist approach lost influence on policy makers he kept defending the importance of many of its principles. In this paper we survey and assess the impact on monetary economics of Laidler's work on the demand for money and the quantity theory of money; the transmission mechanism on the link between money and nominal income; the Phillips Curve; the monetary approach to the balance of payments; and monetary policy.
