We discuss the idea of a purely algorithmic universal world iCurrency in light of recent developments, including Libra. We analyze the Libra proposal, including the stability and volatility aspects, and discuss various issues to be addressed. For example, one cannot expect a cryptocurrency such as Libra to trade in a narrow band without a robust monetary policy. A technical appendix (available online) provides a detailed mathematical description of the (crypto) FX rate dynamics in target zones.

The main purpose of this paper is to report on the results of an exhaustive reworking of Argentina’s output growth by industry realized by the ARKLEMS+LAND Argentina Productivity and Competitiveness Project. The aim was to reproduce a GDP time series since 1993 using traditional Argentinean national accounting methodology in order to check economic growth against official statistics produced after political intervention in the work of the National Statistics institute since 2007. The reproduced ARKLEMS GDP series closely approximates to official GDP between 1993 and 2007 at macro and industry level. But after 2007, Official series showed a higher growth than ARKLEMS reproducible (29.4% Official GDP vs. 15.9% ARKLEMS GDP for 2007–2012). However, the gap between the series is not related to the use of biased CPI deflators, but it is due to the abandoning of traditional methodology followed by Argentinean national accounts prior to its intervention. The paper shows that Argentina’s recent growth episode of 2002–2012 was similar to the previous positive growth cycle period of 1990–1998. Argentina was not the growth champion of the Latin America region during the later period, but it has one of the highest rates of volatility of GDP across Latin America. Argentine official GDP data has been subject to the so-called ‘Pandora’s Box’ effect as a result of the political intervention in the production of official statistics.

Revisions of national accounts affect economic analysis, calling into question theoretical findings based on earlier data. Revisions to German national accounts have resulted in a markedly higher GDP in absolute terms and a lower volatility in macroeconomic production. According to the revised data, recessions have been less pronounced. Moreover, less volatility in production has changed income accounts and, above all, reduced the fluctuations in property and entrepreneurial income. The stylised fact of declining property and entrepreneurial incomes during recessions in West Germany from 1970 to 1991 has vanished into thin air as a result of the revisions of 2002 and 2006.
