It is widely debated whether a monetary union has to be accompanied by a fiscal transfer scheme to accommodate asymmetric shocks. We build a model of a monetary union with a central bank and two heterogeneous countries that are linked by a fiscal transfer scheme with repercussions on monetary...

The paper examines the monetary-fiscal interactions in a monetary union model with uncertainty due to imperfect central bank transparency. We first show that monetary uncertainty disciplines fiscal policymakers and thereby reduces taxes, average inflation and output distortions. However, as more...

We analyze how the combined effect of automatic stabilizers and discretionary changes in taxbenefit systems have affected the cushioning of income shocks in the Euro zone and the EU-27 in the period 2007-2014. We propose a new summary measure of the combined effect of automatic stabilizers and...

The COVID-19 pandemic has led to an increase in public debt in most countries. This will increase fiscal pressure in the future. We study how the shape of the optimal nonlinear income tax schedule is affected by this increase. We calibrate the workhorse optimal income tax model to five European...

OPTIMThe conservative central banker has come under attack recently. Explicitly modeling the interaction of a trade union with monetary policy, it has been argued that the standard solution to the inflationary bias in monetary policy might actually be welfare reducing if the trade union has an...

What is the optimal institutional structure for an independent central bank? The paper shows when it will be optimal for a country to have a central bank to be organized according to federal, purely national or a combination of both aspects. The analysis is then extended to a supranational...

The pending enlargement of the European Monetary Union (EMU) has brought to the fore the discussion of the voting right distribution in the European Central Bank (ECB) council. We show that, in a model where labor unions internalize the inflationary consequences of wage setting, deviating from a...

What policy objective should a common central bank in a heterogeneous monetary union pursue? Should it base its decisions on the EU-wide average of inflation and growth or should it instead focus on (appropriately weighted) national welfare losses based on national rates of inflation and growth?...

This paper explores how the introduction of an experience rated system of unemployment insurance affects employment and welfare in a model where implicit contracts between firms and workers give rise to wage rigidities and unemployment. In the literature, it has been argued that experience rated...

This paper analyses the impact of immigration on the welfare of the native population in an economy that consists of skilled and unskilled workers. Due to unionisation, the wage rate in the market for unskilled labour is above the competitive level. For a given skill endowment of the native...
