Ricardo Reis is a professor of economics at the London School of Economics and a returning guest to the podcast. Ricardo rejoins Macro Musings to talk about central bank swap lines, the importance of fiscal sustainability, and the outlook for inflation in advanced economies. David and Ricardo also discuss safe asset alternatives, and how to think about inflation, debt, and deficits in a more nuanced way.   Transcript for the episode can be found here: https://www.mercatus.org/bridge/tags/macro-musings   Ricardo’s Twitter: @R2Rsquared Ricardo’s LSE profile: https://personal.lse.ac.uk/reisr/   Related Links:   *Central Bank Swap Lines* by Saleem Bahaj and Ricardo Reis https://voxeu.org/article/central-bank-swap-lines   *Central Bank Swap Lines During the Covid-19 Pandemic* by Saleem Bahaj and Ricardo Reis https://personal.lse.ac.uk/reisr/papers/20-covicbswaps.pdf   *The Constraint on Public Debt When r < g but g < m* by Ricardo Reis https://iepecdg.com.br/wp-content/uploads/2020/12/mpkrg-201112.pdf   *Inflating Away the Public Debt?
