Variance Decomposition Networks
Diebold and Yilmaz (2015) recently introduced variance decomposition networks as tools for quantifying and ranking the systemic risk of individual firms. The nature of these networks and their implied rankings depend on the choice decomposition method. The standard choice is the order invariant generalized forecast error variance decomposition of Pesaran and Shin (1998). The shares of the forecast error variation, however, do not add to unity, making difficult to compare risk ratings and risks contributions at two different points in time. As a solution, this paper suggests using the Lanne-Nyberg (2016) decomposition, which shares the order invariance property. To illustrate the differences between both decomposition methods, I analyzed the global financial system during 2001 – 2016. The analysis shows that different decomposition methods yield substantially different systemic risk and vulnerability rankings. This suggests caution is warranted when using rankings and risk contributions for guiding financial regulation and economic policy.
Competition
The proliferation of economic agents with market power, especially those operating in the digital economy and which add unprecedented dynamic and complexity to it, has sparked heated discussions among academics, professionals, and competition authorities around the world regarding the effects of their actions on the market and consumers. Unlike classic cartels – a conduct that has been treated as per se unlawful in Brazil, regardless of the production of effects under Brazilian competition law – unilateral conduct falls into a gray area, encompassing different practices with different effects on the market. In this sense, examples of unilateral conduct that may be considered anticompetit...

Cryptocurrency taxation
O livro tem como elemento central a análise de fatos geradores tributários decorrentes do uso de criptomoedas como ativos de pagamentos (principalmente) e investimentos (residualmente). A premissa perpassa pela necessidade de se descobrir quais as pessoas operam as criptomoedas, uma vez que a chave pública não identifica o CPF ou CNPJ do usuário. A falta de reconhecimento entre a pessoa física e o algoritmo que compõe a chave pública permite a circulação de riqueza sem a respectiva tributação. Desse modo, o presente livro pretende responder às seguintes indagações: como lidar com a circulação de riquezas quando o ativo transferível, por chave pública, não propicia a ident...
