This paper reviews the key economic issues concerning the welfare costs of inflation and deflation, with a view to shedding light on the desirable properties of the inflation process. Our review of the evidence on the overall costs of inflation and deflation indicates that such costs could be...

Societies provide institutions that are costly to use, but able to enforce long-run relationships. We study the optimal decision problem of using self-governance for risk sharing or governance through enforcement provided by these institutions. Third-party enforcement is modelled as a costly...

When people share risk in financial markets, intermediaries provide costly enforcement for most trades and, hence, are an integral part of financial marketsu0092 organization. We assess the degree of risk sharing that can be achieved through financial markets when enforcement is based on the...

The EU Action Plan on Drugs 2013-2016 requires EU member states to ‘provide, where appropriate and in accordance with their legal frameworks, alternatives to coercive sanctions (such as education, treatment, rehabilitation, aftercare and social integration) for drug using offenders’. The EU...

This paper investigates the performance of optimised interest rate rules when there is uncertainty about a key determinant of the monetary transmission mechanism, namely the degree of persistence characterising the inflation process. The paper focuses on the euro area and utilises two variants of...

This paper summarises the results of a quantitative study of the possible impact of downward nominal wage rigidity on the determination of inflation and output in the euro area and the existence of a non-vertical long-run Phillips curve. The study was undertaken in the context of the review of...

The presence of a lower bound of zero on nominal interest rates has important implications for the conduct of optimal monetary policy. Standard rational expectations models can have alternative steady states as well as non-unique laws of motion, i.e. there can be possible sunspot equilibria....

In the context of a stylised game theoretical framework of capital tax competition, we show that when repeated policy interactions are associated to a systematic punishment of the deviating policymaker, a co-ordinated outcome can be the solution to the non co-operative tax game. This result...

Starting from an overview of the political background of the Kosovo issue, rooted in Serb and Albanian history, the paper then describes the main features of the current situation: "nothing more than autonomy" from one side, "nothing less than independence" for the other. Against this...
