The paper discusses some fundamental problems in monetary economics associated with the determination and role of the numéraire. The issues are introduced by formalising a proposal, attributed to Eisler, to remove the zero lower bound on nominal interest rates by unbundling the numéraire and...

A striking fact about prices is the prevalence of ``sales': large temporary price cuts followed by a return exactly to the former price. This paper builds a macroeconomic model with a rationale for sales based on firms facing consumers with different price sensitivities. Even if firms can vary...

This paper documents some stylized facts on evolving UK Phillips curves, and shows how these differ from their US versions. We interpret UK Phillips curve dynamics in a positive theory of monetary policy û how policy-maker attitudes on the Phillips curve have evolved since the 1950s û rather...

I analyze optimal monetary policy in an economy with search and matching frictions in the labor market and staggered nominal wage and price contracts. In this framework, as opposed to the standard New Keynesian model, preset nominal wages need not have any effect on existing employment...

The standard New Keynesian model suffers from the so-called .macro-micro pricing conflict: in order to match the dynamics of inflation implied by macroeconomic data, the model needs to assume an average duration of price contracts which is much longer than what is observed in micro data. Here I...

This paper develops a simple model to analyze how a lack of political competition may lead to policies that hinder economic growth. We test the predictions of the model on panel data for the US states. In these data, we find robust evidence that lack of political competition in a state is...

Germany's Great Depression of the early 1930s started in 1929 with a sudden stop in the current account. It ended after a foreign debt default that unfolded in several stages from 1931 to 1933. This chapter reviews Germany's macroeconomic history between the gold-based stabilisation of 1924 and...

The prominent role of monetary policy in the U.S. interwar depression has been conventional wisdom since Friedman and Schwartz (1963). This paper presents evidence on both the surprise and the systematic components of monetary policy between 1929 and 1933. Doubts surrounding GDP estimates for...
