In this paper, we present Velocity, a decentralized market deployed on Ethereum for trading a custom type of derivative option. To enable the smart contract to work, we also implement a price fetching tool called PriceGeth. We present this as a case study, noting challenges in development of the system that might be of independent interest to whose working on smart contract implementations. We also apply recent academic results on the security of the Solidity smart contract language in validating our codes security. Finally, we discuss more generally the use of smart contracts in modelling financial derivatives.
Cryptocurrencies, such as bitcoin and ethereum, have not only risen to public attention as novel means of payments, but also as facilitators of initial coin offerings (ICOs, also called token sales). In these entirely online-mediated offerings, entrepreneurs sell tokens registered on a blockchain in exchange for cryptocoins. Buyers receive tokens that can be understood as cryptographically-secured coupons which embody a bundle of rights and obligations. In July 2017, the SEC released an investigative report that highlighted that such tokens can be subject to the full scope of US securities regulation. It is unclear, however, to what extent EU securities regulation is applicable to ICOs and, particularly, whether issuers have to publish and register a prospectus in order to avoid criminal and civil prospectus liability in the EU. In conceptual terms, this depends on whether tokens are considered “securities” under the EU prospectus regulation regime. Against this background, this paper develops a nuanced approach that distinguishes between three archetypes of tokens: currency, investment, and utility tokens. It analyzes the differential implications of each of these types, and their hybrid forms, for EU securities regulation, and develops policy proposals for their regulation.
The practice of securities holding, transfer, and collateral has changed significantly over the past 200 years—moving from paper certificates and issuer registers, to an intermediated environment, and from there to computerization and globalization. These changes have made transacting more efficient and thus rendered markets more liquid. However, the law has lagged behind and is now itself an obstacle to efficiency because international securities transactions are subject to considerable legal uncertainty. The latest global market development, a cryptographic transfer process commonly called the blockchain, is the most recent efficiency-enhancing change. It offers a unique possibility to create a consistent legal framework for securities from scratch, on the basis of a legal concept that, to some extent, resembles bearer securities. This article shows what the new international legal framework could look like in the light of experience gained from earlier developments.
The blockchain technology underlying Bitcoin and other cryptocurrencies is attracting growing interest. This column argues that if transactions facilitated by this technology become per-vasive, it will have implications for the conduct (and success) of central bank monetary policy. Central banks should embrace the technologies that underpin cryptocurrencies, or risk being cut out from intermediation and surveillance and also risk payment service providers moving to other currency areas with an institutional environment that is more appealing for buyers and sellers.
Earlier research on the links between economic growth and credit market development has abstracted from interactions between labour and financial markets. Moreover, most studies have analysed macro‐finance linkages at the aggregate level, ignoring the decentralized nature of search and matching in labour and credit markets. This paper fills this void and thus allows for a more disaggregate analysis of policy effects. We show that the credit market exacerbates and accentuates the labour market effects, having amplifying effects on output, consumption, employment and welfare. Depending on the strength of the debt‐dynamics, several growth dynamics emerge from this interaction between labour and credit markets with two distinct steady states: a stable growth regime and another one that is vulnerable and unstable. To test the empirical implications of the theoretical model, a multi‐regime VAR (MRVAR) model is fitted to the US output and credit market data. The MRVAR estimation indicates that shocks to credit conditions during a high‐growth period have markedly different effects than during a low growth and recessionary period. Also, there are substantial state‐dependent asymmetries with respect to the sign of shocks to credit conditions, confirming the theoretical predictions.
ABSTRACT The payments landscape is changing. Checks and cash are declining and being;replaced by electronic instruments; a range of new players are taking aim at the role;and position of banks; and new technologies such as Bitcoin/Distributed Ledger are;even challenging the nature of money itself. An often-heard argument is "a payment;is a payment", implying that a new player with a superior technology or customer;proposition, if successful, would be able to ultimately replace all existing payment;instruments/systems. This paper argues that the current payments landscape consists;of segments with inherently different characteristics that require different approaches.;Most dynamics occur within such segments, rather than across them.

Evolved by way of an anonymous programmer, Bitcoin is a global cryptocurrency and a machine for virtual currency.The transactions take location immediately among the users minus any intermediaries.Bitcoin is an awesome mode of exchange whilst in comparison to traditional banks.Those transactions are verified through network nodes and recorded in a public dispensed ledger called blockchain.The price of bitcoins are volatile i.e. they could unpredictably boom or lower over a quick time period.They are taken into consideration excessivedanger assets whose transactions can simplest be refunded and not reversed.The bitcoin came into life in January 2009, with Satoshi Nakamoto mined the primary block of bitcoins ever.Given that then, some of supporters engaged in transactions and acquired bitcoins.International locations round the world started out accepting bitcoin as a legitimate mode of currency like the United States.However, some countries like Djibouti haven't legalized yet the usage of this foreign money due to some of reasons.The targets of this paper are to understand the awareness about the existence of bitcoins, to evaluate the perception of bitcoin as the future currency and to research the possibility of legalization of bitcoins in Djibouti.
Central banking in an age of digital currencies is a fast-developing topic in monetary economics. Algorithmic digital currencies such as bitcoin appear to be viable competitors to central bank fiat currency, and their presence in the marketplace may pressure central banks to pursue tighter monetary policy. More interestingly, the blockchain technology behind digital currencies has the potential to improve central banks' payment and clearing operations, and possibly to serve as a platform from which central banks might launch their own digital currencies. A sovereign digital currency could have profound implications for the banking system, narrowing the relationship between citizens and central banks and removing the need for the public to keep deposits in fractional reserve commercial banks. Debates over the wisdom of these policies have led to a revival of interest in classical monetary economics.
Purpose Given its innovative characteristics and increasing popularity, the Bitcoin, and other virtual currencies, are expected to become mainstream, leading to the need for a generally accepted accounting treatment. Currently, however, there are no accounting standards which offer guidance on the recognition and measurement of these virtual currencies. To this end, the purpose of this paper is to determine a conceptual approach for accounting for the Bitcoin, grounded in the theories of neoliberalism and stewardship. Design/methodology/approach The research adopts an interpretive mixed-method approach. The relevant literature is analysed to identify key characteristics of the Bitcoin. These, as well as the elements of accounting policies inspired by neoliberalism and stewardship, form row and column headings in a correspondence matrix completed by 40 financial reporting experts. The correlations between rows and columns (developed using principal component analysis) are used to identify possible recognition and measurement requirements for the Bitcoin. Semi-structured interviews are used to complement the correspondence analysis. Findings The correspondence analysis and interviews reveal an emphasis on cost and fair value proposed by models grounded in stewardship and neoliberalism, respectively. The primary factor at work is the need to account for the underlying economics of the unit of account, something which is informed heavily by an organisation’s business model. Cost and fair value may be conceptual opposites, but in the eyes of respondents, these need to be used to achieve the single goal of communicating the economic rationale for holding the Bitcoin. Research limitations/implications The study is based on a purposefully selected sample of experts and lacks the exploratory potential of purely qualitative research. Nevertheless, it makes novel use of a correspondence analysis to provide an initial frame of reference for developing an accounting policy for unusual transactions and balances. Originality/value The paper is the first to provide a normative perspective on the accounting for this poorly understood “currency”. It also adds to the limited body of interpretive accounting research which dispenses with traditional finance paradigms and positivist models to provide practical recommendations. Finally, the paper offers an innovative approach, using a correspondence analysis and detailed interviews, for developing an accounting policy for transactions not specifically within the scope of existing accounting standards.
In most countries, the central bank is required to hold reserve assets as a means of providing credibility for the value of the fiat currency. These assets can be in the form of gold, foreign exchange or some other internationally recognised reserve asset and are held to permit the country to engage in international transactions. Within recent years, cryptocurrencies have been increasingly utilised for international transactions, and it is possible that the use of these cryptocurrencies might expand in the future. This paper therefore examines the potential role of digital currency balances as part of the portfolio of external assets held by a central bank. Using the case of Barbados, the paper also provides a simulation of the effect holding some proportion of their asset-base would have had on the stability of the foreign reserves as well as the return on the portfolio of assets.
This dissertation is a compilation of three papers that investigate the role of optimal contracting in a delegated portfolio management setting. While the study of optimal contracts in classical principal-agent setup has been extensively studied, relatively few have been studied in the context of delegated portfolio management in finance. And even delegated portfolio management papers in finance, there are still several open questions and unresolved issues that are beyond the scope of a standard principal-agent problem. In Chapter 1, I study a continuous-time principal-agent problem with drift and stochastic volatility control. While the problem with drift-only control by an agent has been extensively studied recently, very few existing papers allow an agent to endogenously influence volatility. Endogenous volatility control is particularly important in delegated portfolio management settings as volatility is one of the defining aspects of modern financial portfolio management. In Chapter 2, I study a model that encompasses dynamic agency, delegated portfolio management and asset pricing. Traditionally, the fields of ``asset pricing'' and ``corporate finance'' are studied independently of each other. However, as the modern portfolio management industry blooms in size and influence, the role of the portfolio manager and the contracts that are extended to them arguably has a role in the securities that they invest in, and hence in equilibrium, the asset pricing implications of the market overall. This paper is an attempt to bridge ``asset pricing'' and ``corporate finance'' (specifically interpreted to mean delegated portfolio management contracting) into one. In Chapter 3, I study whether a principal investor is better off delegating most of his money to a single portfolio manager (centralized delegation), as opposed to multiple portfolio managers (decentralized delegation), especially when there is the possible presence of moral hazard. With the size of the hedge fund industry and growing empirical support that moral hazard is a growing risk among hedge fund managers, it becomes imperative to understand when an investor decides to delegate his money, should it be delegated in a more centralized or decentralized fashion.
Bitcoin is the most popular virtual currency yet developed. Proponents assert that bitcoin can remove frictions involved in payment and settlement systems by eliminating the need for the financial intermediaries that exist in traditional currencies. In this blog post, we show that while bitcoin transfers themselves are relatively frictionless for the user, there are significant frictions when bitcoins trade in exchange markets resulting in meaningful and persistent price differences across bitcoin exchanges. These exchange-related frictions reduce the incentive of market participants to use bitcoin as a payments alternative.
The objective of this article is to analyze the tie between the financings of the Decentralized Financial System (DFS) and the agricultural growth in Senegal. We use a linear equation model. The survey covers the active period of 1999 to 2013. Results show that the Decentralized Financial System has a positive and significant impact on the agricultural GDP in Senegal.
This paper provides a theory of external and internal finance where entrepreneurs finance random investment opportunities with fiat money, bank liabilities, or trade credit. Loans are distributed in an over-the-counter credit market where the terms of the loan contract, including size, rate, and down payment, are negotiated in a decentralized fashion subject to pledgeability constraints. The model has implications for the cross-sectional distribution of corporate loan rates and loan sizes, interest rate pass-through, and the transmission of monetary policy (described either as money growth or open market operations) with or without liquidity requirements.
In this paper, we analyse the workings of commercial banks in a scenario where crypto-currencies are the mainstream bills of exchange. We start by explaining the concept of cryptocurrencies (also referred to as cryptocoins in this paper). Then we discuss the concept of Regulated and Sovereign Backed Cryptocurrencies (RSBCs). Later on, we envisage a scenario where cryptocoins are the main media of exchange. The banking aspects of Paper money, Bitcoins and RSBCs are then deliberated. We analyse the interplays between Banking and various currency formats. Finally, the paper concludes as to which currency is best suited to be the mainstream bill of exchange.
