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 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...

Financial crisis can trigger policy reversals, i.e. they can lead to a process of re- regulation of financial markets. Using a recent comprehensive dataset on financial liberalization across 94 countries for the period between 1973 and 2015, we formally test the validity of this prediction for...

The optimal currency areas (OCA) theory has been influential in pushing eurozone countries towards structural reforms to make product and labour markets more flexible. The underlying assumption of the OCA prescription for structural reform is that asymmetric shocks are permanent. However, when...

It is well-known that the high synchronization of the business cycles among industrial countries cannot easily be replicated in standard open economy macroeconomic models without assuming that the exogenous shocks hitting these countries are highly correlated. We develop a two-country behavioral...

We first present a simple model of post-crisis policymaking driven by both public and private interests. Using a novel dataset covering 94 countries between 1973 and 2015, we then establish that financial crises can lead to government interventions in financial markets. Consistent with a public...

In this paper we test two theories of the determination of the government bond spreads in a monetary union. The first one is based on the efficient market theory. According to this theory, the surging spreads observed from 2010 to the middle of 2012 were the result of deteriorating fundamentals...

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...
