O bitcoin como moeda paralela: uma visão econômica e a multiplicidade de desdobramentos jurídicos

A existência de instrumentos monetários paralelos àqueles “oficiais” não é um fenômeno recente: ao longo da história, diversas foram as formas e ocasiões em que circularam moedas paralelas. No entanto, nos últimos anos, esses instrumentos fundiram-se com a tecnologia, atingindo um alcance praticamente ilimitado, trazendo consequências que ainda não se sabe como estimar. Este trabalho tem por objetivo estudar um caso específico de moeda paralela de alta complexidade tecnológica, o Bitcoin, e descrever quais têm sido os posicionamentos adotados por uma série de jurisdições a esse respeito. Trata-se de uma aproximação mais palatável da linguagem da Tecnologia da Informação e da Economia aos operadores do Direito. O estudo estende-se na direção de propor uma reflexão acerca do significado de se reconhecer no Bitcoin uma moeda paralela – muito embora a discussão acerca de ser ou não moeda constituir apenas uma das discussões possíveis. Explora-se quais têm sido as opções de regulação adotadas pelos Estados que se vêem obrigados a assumir uma posição em relação às moedas virtuais, em geral, e ao Bitcoin, em particular. Percebe-se que a terminologia escolhida pelas jurisdições no tratamento do Bitcoin resulta na sua inclusão em diferentes categorias do Direito e, como consequência direta disso, as implicações jurídicas variam de acordo com a terminologia adotada. O principal tratamento dispensado ao Bitcoin é aquele via tributação, notando-se a preocupação de cada Estado em classificar juridicamente o Bitcoin de acordo com a regulação específica que se pretende invocar a incidência. De acordo com o levantamento realizado, 62 jurisdições já assumiram um posicionamento em relação ao Bitcoin. Com cada vez mais atenção dispensada por órgãos regulatórios internacionais – como é o caso do Banco Central Europeu e do Fundo Monetário Internacional – o Bitcoin reforça seu potencial e suas limitações, principalmente no tocante aos desafios enfrentados à uma regulação eficaz. A conclusão deste trabalho procura reforçar que o tratamento jurídico dispensado a fenômenos novos não é uniforme, e que, uma vez encarado pelo viés da teoria econômica que reconhece a existência das moedas paralelas, o Bitcoin pode ser mais facilmente apreendido em um aparato regulatório.

Vacina contra doença holandesa

O objetivo destas Notas é resenhar o atual debate sobre a inserção da economia brasileira no contexto mundial, particularmente, se o Brasil pode se prevenir do risco de enfrentar a chamada “doença holandesa”. Há debate inconcluso a respeito do seu diagnóstico. Alguns economistas acham que ela já está apresentando seus sintomas através da apreciação excessiva da moeda nacional e redução relativa dos empregos industriais. Outros opinam que ela, de fato, atacará em longo prazo, quando a exportação do petróleo extraído do pré-sal estiver em pleno ritmo. Iniciaremos esboçando o contexto vivenciado e o cenário esperado. Em seguida, exercitaremos a Economia Positiva, ou seja, apresentaremos as posições em debate sobre o que é. Finalizaremos com Economia Normativa, isto é, as propostas sobre o que deve ser.

Europe’s financial crisis: the Euro’s flawed design and the consequences of lack of a government banker

This paper argues the euro zone requires a government banker that manages the bond market and helps finance country budget deficits. The euro solved Europe’s problem of exchange rate speculation by creating a unified currency managed by a single central bank, but in doing so it replaced the exchange rate speculation problem with bond market speculation. Remedying this requires a central bank that acts as government banker and maintains bond interest rates at sustainable levels. Because the euro is a monetary union, this must be done in a way that both avoids favoring individual countries and avoids creating incentives for irresponsible country fiscal policy that leads to “bail-outs”. The paper argues this can be accomplished via a European Public Finance Authority (EPFA) that issues public debt which the European Central Bank (ECB) is allowed to trade. The debate over the euro’s financial architecture has significant political implications. The current neoliberal inspired architecture, which imposes a complete separation between the central bank and public finances, puts governments under continuous financial pressures. That will make it difficult to maintain the European social democratic welfare state. This gives a political reason for reforming the euro and creating an EPFA that supplements the economic case for reform.

Notes on cyclical tendency to the overvaluation of the real

This note addresses the question “To what extent financial regulation in Brazil was effective in neutralizing the tendency to the overvaluation of the exchange rate in Brazil since the 1994 Real Plan?” Aiming at answering this question, this note is organized as follows: after this short introduction, we briefly describe the Brazilian exchange rate behavior after the Real Plan, emphasizing its key role in keeping prices stable. In section 3, the recent measures adopted by the Brazilian Central Bank (BCB) aiming at avoiding the overvaluation of real will be summarized. In section 4, we argue in favor of a new policy mix that could avoid overvaluation of the currency. Finally, some issues will be raised in order to effectively neutralize the overvaluation of real.

A note on financial regulation and the brazilian response to the 2008‐09 financial crisis

Brazil was frequently criticized for its interventionist and heavy financial regulation up until the 2008‐09 world financial crisis.  According to the neo‐liberal or pro‐market view that predominated in academic and financial circles during the early 2000s, economic development came together with financial deepening, which in its turn could only be achieved through financial liberalization and deregulation. The currency crises of the 1990s notwithstanding, by the mid‐2000s Brazil’s segmented financial market and its restrictive reserve and capital requirements were seen as a symbol of inefficiency and backwardness by most financial specialists.  To the luck of the Brazilian population, most of the advices of such specialists were ignored by the Brazilian authorities, so that, when the 2008 financial crisis hit the world economy, Brazil still had powerful and efficient instruments to deal with the problem.  The objective of this note is to present the mains aspects of the Brazilian financial regulation and how they helped the economy to deal with the consequences of 2008‐09 financial meltdown.

Monetary policy, default risk and the exchange rate

In a country with high probability of default, higher interest rates may render the currency less attractive if sovereign default is costly. This paper develops that intuition in a simple model and estimates the effect of changes in interest rates on the exchange rate in Brazil using data from the dates surrounding the monetary policy committee meetings and the methodology of identification through heteroskedasticity. Indeed, we find that unexpected increases in interest rates tend to lead the Brazilian currency to depreciate. It follows that granting more independence to a central bank that focus solely on inflation is not always a free-lunch.

Trade rules and exchange rate misalignments : in search for a WTO solution e medidas compensatórias

The debate on the link between trade rules and rules on exchange rates is raising the attention of experts on international trade law and economics. The main purpose of this paper is to analyze the impacts of exchange rate misalignments on tariffs as applied by the WTO – World Trade Organization. It is divided into five sections: the first one explains the methodology used to determine exchange rate misalignments and also presents its results for Brazil, US and China; the second summarizes the methodology applied to calculate the impacts of exchange rate misalignments on the level of tariff protection through an exercise of “misalignment tariffication”; the third examines the effects of exchange rate variations on tariffs and their consequences for the multilateral trading system; the fourth one creates a methodology to estimate exchange rates against a currency of the World and a proposal to deal with persistent and significant misalignments related to trade rules. The conclusions are present in the last section

5th BRICS Trade and Economic Research Network (TERN) meeting: the impact of mega agreements on BRICS

The BRICS TERN – BRICS Trade and Economics Research Network is a group of independent research institutes established four years ago by five think tanks from Brazil, Russia, India, China and South Africa. The main objective of the network is to study different aspects of trade and economic relations amongst these five countries. The purpose of the V BRICS TERN Meeting was to analyze and debate the effects of the negotiations of the Mega Agreements, mainly those initiated by the US and the EU, already in negotiation, to each of the BRICS Trade Policies. Both Mega Agreements were examined – the Trans Pacific Partnership (TPP) and the Transatlantic Trade and Investment Partnership (TTIP). The studies included the main impacts on trade flows and on the international trade rules system, respecting the perspective of each of the countries concerned. This workshop was an initiative of the Center for Global Trade and Investments (CGTI), a think-tank on International Trade held by FGV Sao Paulo School of Economics. Its main objective is the research on trade regulation, preferential trade agreements, trade and currency, trade and global value chains, through legal analysis and economic modelling. One of its main researches, now, is on the potential economic and legal impacts of the Mega Agreements on Brazil and WTO rules. This meeting was organized in March14, 2014, in Rio de Janeiro, in a perfect timing for introducing such issues in the international agenda, in advance of the 6th BRICS Summit scheduled to be held in Brazil in July 2014.

O diferencial entre as curvas de juros doméstica e externa em reais é uma evidência para o argumento de "incerteza jurisdicional"?

O trabalho faz uma análise sobre as taxas de juros brasileiras, além das principais características da curva soberana de juros nominais, dando ênfase aos títulos pré-fixados emitidos pelo governo em moeda local, no mercado doméstico e externo, onde notamos a ocorrência de um fenômeno bastante peculiar, que é o diferencial de rendimento e de maturidade existentes entre os dois mercados. Arida, Bacha e Lara-Resende (2004) conjecturam sobre a existência de um risco inerente ao país, chamado por eles de “incerteza jurisdicional”, relacionado às instituições brasileiras, e que estaria por trás das altas taxas de juros e da inexistência de um mercado de crédito doméstico de longo prazo. É feito um diagnóstico mais detalhado sobre as possíveis causas do fenômeno de maior maturidade e menor rendimento dos títulos emitidos no mercado externo em relação aos títulos do mercado interno, notando-se que ambos os fenômenos – dos altos juros brasileiros e da inexistência de um mercado juros de longo prazo – estão diretamente relacionados. As conclusões sobre as possíveis causas para o diferencial de rendimento entre os títulos locais e externos emitidos em Reais dizem respeito tanto aos fatores quantitativos, relacionados aos custos de investimento no Brasil e ao risco de conversibilidade, que contribuem em parte para aumentar as taxas exigidas para os títulos locais, bem como aos fatores qualitativos, como piores instituições no Brasil em relação às instituições externas. A diferença de maturidade entre os títulos também advém de questões institucionais, o que reafirma de certo modo a teoria de “incerteza jurisdicional” para explicar este fenômeno.

Capital misallocation and mitigating policies

The purpose of this work is to study the role for government in mitigating capital misallocation. We develop an entrepreneurship model in which heterogeneous producers face collateral constraints on production, but can hedge idiosyncratic shocks. Hedging works as a tool for reallocating resources to states in which they are more productively deployed, and can alleviate the effect of the financial frictions and be a counteracting force to capital misallocation. Government incentives to hedging improve workers’ welfare in steady state through an increase in TFP and wages. The intervention leads to a reduction in the rate of return of entrepreneurs and an increase in wealth dispersion. These two effects cause entrepreneurial welfare to decrease.

Welfare cost of inflation considering adoption decisions and interest-bearing deposits

Attanasio et al. (JPE, 2002) have used microeconomic data on households to provide new estimates of the welfare costs of infiation using Bailey's unidimensional welfare measure as a basis for their calculations. Such a measure does not properly take into consideration lhe fact that the majority of households in their sample (58.7 percent) holds not only bank deposits and currency, but also a second type of interest-bearing assct. This work devises alternative formulas which account for the existence of bank deposits and a sccond interest-bearing asset in the economy, as well as for adoption decisions regarding alternative financiai technologies.
