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...

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...

The empirical literature on central banking has found measures of central bank independence/conservatism to be negatively correlated with inflation and inflation variance across countries. But the cross-country approach has been criticised for its focus on policy outcomes instead of policies,...

Soon, euro area membership could more than double, with the vast majority of accession countries being quite different in economic terms compared with current members. Under the current decision-making system, this can lead to high decisionmaking costs and there is a risk that monetary policy...

Beginning with the Reserve Bank of New Zealand Act of 1989, central banking reforms have focused on assigning clear goals for which monetary policy authorities can be held accountable. Inflation targeting regimes provide examples of such goal-based policy frameworks. An alternative approach,...

Many inflation targeting central banks are facing calls to expand their list of policy goals. I discuss how recent research provides new insights into the goals of policy and the tradeoffs presented by multiple goals. I focus particular attention on the role of unemployment and labor market...

The likely extension of the euro area has triggered a debate on the organization of the ECB, in particular on the apparent mismatch between relative economic size and voting rights in the Council. We present a simple model of optimal representation in a federal central bank addressing this...

In this paper we study the evolution of central banks' balance sheets in 12 advanced economies since 1900. We find that balance sheet size in most developed countries has fluctuated within rather clearly defined bands relative to output. Historically, clusters of big expansions and contractions...
