Retail prices of major drugs like cocaine and heroin have declined dramatically during the last two decades. This price decline has tended to offset the effects of drug policies aimed at reducing drug use in major industrial countries. The main finding of this paper is that the decline in the...

There is a wide consensus that the existence of structural rigidities in the Eurozone reduces the effectiveness of the ECB's monetary policies. In order to test this ?ECB-handicap? hypothesis, we perform a meta-analysis of the effects of monetary policies in the US and the Eurozone countries....

In this paper we perform a meta-analysis of the effects of monetary policies on output and prices. We use a sample of published papers on the effects of monetary policies in different countries. There is a large variation in the estimated effects of monetary policies on output and prices. We...

There is thus a fundamental credibility issue about the willingness of the ECB to be a lender of last resort in the government bond markets. This will continue to make the eurozone a fragile construction. As a result, the possibility of a future euro crisis cannot be excluded.

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 test whether the relationship between the nominal exchange rate and the news in its underlying fundamentals has non-linear features. In order to do so, we develop a Markov switching model and apply it to a sample of low and high inflation countries. The empirical analysis shows that for the...

We analyse a card payment system to assess the economic impact of the interchange fee. This fee is paid by the bank of the merchant, the acquirer, to the bank of the consumer, the issuer. We build up a mode in order to explore whether the interchange fee can enhance the participation to the...

We evaluate the policy of flexible inflation targeting implemented by the Norges Bank since March 2001. We discuss the reasons why the real interest rates are significantly higher in Norway than in the rest of Europe. Finally we propose some institutional changes that can improve the policy...

In this paper we develop a model of the exchange rate. The existence of transactions costs introduces an important non-linearity. Agents have different beliefs about the future exchange rate. We show that this simple model creates great complexity in the market which is characterised by the fact...
