Several countries face the choice between targeting inflation independently and entering a monetary union that targets inflation. The present paper extends the theory of optimum currency areas to deal with this choice. In contrast to the conventional theory, countries might form more of an...

Decision rules matter for monetary policy in a currency union if the interest rate affects member states differently. We examine the consequences for inflation, output and interest rate fluctuations and the welfare loss of four alternative types of decision procedures. We show that the...

The discursive dilemma implies that the policy decision of a board of policymakers depends on whether the board reaches the decision by voting directly on policy (conclusion-based procedure), or by voting on the premises for the decision (premise-based procedure). We derive results showing when...

We suggest that overconfidence among policymakers explains why formal decision power over monetary policy is given to committees, while much of the real power to set policy remains with central bank chairmen. Overconfidence implies that the chairman underweights advice from his staff, increasing...

Monetary policymakers face considerable uncertainty and have to use judgment. When the monetary policy committee (MPC) has to reach a decision based on different judgments among its members, various judgment aggregation problems may occur. Here, we consider an aggregation problem called the...

National accounts data are always revised. Not only recent data, but also figures dating many years back can be revised substantially. This means that there is a danger that an important part of the central bank's information set is flawed for a long period of time. In this paper we present a...

Monetary policy works mainly through private agents' expectations. How precisely future policy intentions are communicated has, according to theory, implications for the outcome of monetary policy. Norges Bank has gone further than most other central banks in communicating its policy intentions....

A hybrid inflation/price-level target combines elements of both inflation and price-level targets. The paper derives a hybrid target within a new Keynesian model with inflation persistence due to price indexation. The result generalizes a result by Vestin (2005) that the optimal policy could be...

Most economic decisions involve judgments. When decisions are taken collectively, various judgment aggregation problems may occur. Here we consider an aggregation problem called the "discursive dilemma", which is characterized by an inconsistency between the aggregate judgment on the premises...
