Modern Money Theory (MMT) has generated considerable scrutiny and discussions over the past decade. While it has gained some acceptance in the financial sector and among some politicians, it has come under strong criticisms from all sides of the academic spectrum and from conservative political...

This paper explores under what conditions a European Monetary Union (EMU) is an optimum currency area. The scope for an EMU increases with convergence of structural and fiscal policies, small money holdings, a conservative European Central Bank, and dependent national central banks. How national...

The paper explores the case for monetary and fiscal unification. Monetary policy suffers from an inflation bias because the monetary authorities are not able to commit. With international risk-sharing in a fiscal union, fiscal discipline suffers from moral hazard. An inflation target alleviates...

We reconsider the merits of fiscal policy co-ordination in a monetary union distinguishing between and inflation targeting regime and delegation to a weight conservative central bank. We argue that a contractualist approach a la Walsh should be extended to the conduct of fiscal policy, setting...

We reconsider the issues of fiscal policy interdependence in a monetary union, challenging the view that non co-ordination is always preferable. Moreover, we show that an expenditure bias occurs irrespective of the fiscal regime in place. We argue that a contractualist approach à la Walsh...

Six countries; Qatar, Indonesia, Saudi Arabia, Malaysia, the United Arab Emirates and Turkey (denoted by the acronym QISMUT) are considered the potential primary force of the future international development of Islamic finance. These countries, with both expertise and potential for growth in...

This paper reviews the performance of the euro area since the euro's launch 20 years ago. It argues that the euro crisis has exposed existential flaws in the euro regime. Intra-area divergences and the corresponding buildup of imbalances had remained unchecked prior to the crisis. As those...

We use a dynamic game model of a two-country monetary union to study the impacts of an exogenous fall in aggregate demand, the resulting increase in public debt, and the consequences of a sovereign debt haircut for a member country or bloc of the union. In this union, the governments of...

Financial intermediaries issue the majority of liquid securities, and nonfinancial firms have become net savers, holding intermediaries' debt as cash. This paper shows that intermediaries' liquidity creation stimulates growth -- firms hold their debt for unhedgeable investment needs -- but also...

We study optimal monetary and fiscal policy in a New Keynesian model where occasional declines in agents' confidence can give rise to persistent liquidity trap episodes. Unlike in the case of fundamental-driven liquidity traps, there is no straightforward recipe for mitigating the welfare costs...
