1) de Krugman: (subrayado mío)
2) de Interfluidity (subrayado mío)So what does ail Europe? The truth is that the story is mostly monetary. By introducing a single currency without the institutions needed to make that currency work, Europe effectively reinvented the defects of the gold standard — defects that played a major role in causing and perpetuating the Great Depression. ...If the peripheral nations still had their own currencies, they could and would use devaluation to quickly restore competitiveness. But they don’t, which means that they are in for a long period of mass unemployment and slow, grinding deflation. Their debt crises are mainly a byproduct of this sad prospect, because depressed economies lead to budget deficits and deflation magnifies the burden of debt.
Even though devaluation is no panacea, the nations of peripheral Europe might still wish to consider dropping the Euro. But the case for that is not, ultimately, about relative prices, but about sovereignty and bargaining power. As the MMTers correctly emphasize, control over money is essential to the sovereign power of a state. For now, the nations of the Eurozone have ceded a significant part of their sovereignty to European institutions. That would be fine, if those institutions could be trusted to look out for, or at least give fair weight to, the interests of the states which have surrendered sovereign powers. If I were a citizen of Portugal or Greece, Spain, Ireland, or Italy, I would conclude that European institutions have unduly little concern for my interests and unduly much concern for a transnational financial system and Northern European taxpayers. If that continues, I’d want my government to retract the sovereignty it had ceded, so that it has the freedom to maximize the forward-looking welfare and growth of my nation without hobbling itself in the interests of claimants to past loans that ought never have been made.
