In a world of radical uncertainty the frequency distributions of economic variables deviate from the normal distribution and typically exhibit fat tails. We show that this feature is obtained in simple models where agents have cognitive limitations and fail to understand the underlying model....

The major central banks now operate in a regime of abundance of bank reserves. As a result, they can only raise the money market rate by increasing the rate of remuneration of bank reserves. This, in turn, leads to large transfers of the central banks' profits (and more) to commercial banks that...

This paper provides a critical overview of the state of the art in the economics literature on structural reforms. It takes stock of theoretical developments, measurement efforts and of the econometric evidence. We start with a simple theoretical framework for the relationship between structural...

We test the hypothesis that the government bond markets in the Eurozone are more fragile and more susceptible to self-fulfilling liquidity crises than in stand-alone countries. We find evidence that a significant part of the surge in the spreads of the PIGS countries in the Eurozone during...

We analyze the similarities and the differences in the fragility of the European Monetary system (EMS) and the Eurozone. We test the hypothesis that in the EMS the fragility arose from the absence of a credible lender of last resort in the foreign exchange markets while in the Eurozone it was...

We find evidence that a significant part of the surge in the spreads of the PIGS countries in the Eurozone during 2010-11 was disconnected from underlying increases in the debt to Gdp ratios, and was the result of negative market sentiments that became very strong since the end of 2010. We also...

We analyze the similarities and the differences in the fragility of the European Monetary System (EMS) and the Eurozone. We test the hypothesis that in the EMS the fragility arose from the absence of a credible lender of last resort in the foreign exchange markets while in the Eurozone it was...

The perception that the government bond buying program (OMT) announced by the ECB may lead to future tax burdens on countries, in particular on Germany, is based on an erroneous application of solvency principles that apply to private agents, but not to central banks. We argue that the creditor...

In this paper we provide empirical evidence documenting the nature of the Eurozone’s fragility. We find that during periods of turmoil, financial markets have tended to impose strong programs of austerity on member countries of the Eurozone. This confirms the evidence we found in a previous...

We analyse the similarities and the differences in the fragility of the European Monetary System (EMS) and the Eurozone. We test the hypothesis that in the EMS, the fragility arose from the absence of a credible lender of last resort in the foreign exchange markets; whereas in the Eurozone, it...
