In this paper, we discuss the observational equivalence between two monetary policy rules: a constant money growth rule and an interest rate rule. From the equilibrium conditions of a sticky prices model, we consider: (i) the Taylor rule parameter implied by the model with exogenous money...

In this paper, we investigate the causes and consequences of “unclaimed” unemployment insurance (UI) benefits. A search model is developed where the costs to collecting UI benefits include both a traditional “fixed” administrative cost and an endogenous cost arising from worker and firm...

An annual sequence of wages in England starting in 1245 is used. It is shown that a standard AK-type growth model with capital externality and stochastic productivity shocks is unable to explain important features of the data. Random returns to scale are then considered. Moderate episodes of...

In this paper, we propose a theoretical framework to investigate the impact of conflicts and wars on key macroeconomic aggregates and welfare. Using a panel data with 9 countries from 1870 onwards, we first show that the consumption-to-output ratio is minimal during WWII for participants. While...

[eng] This article examines how monetary policy should be conducted in an open economy when its influence on the extensive margin of trade is taken into account. In a two-country model, we show that – contrary to the results obtained by Bilbiie et alii (2007 ) – the optimal monetary policy...

This paper shows that introducing habit persistence in a limited participation model allows to reproduce a persistent liquidity effect. Furthermore, the decomposition of the monetary effects on nominal interest rate allows to isolate the liquidity premium defined by Fuerst [1992]. Then, we show...

This paper studies the effects of the European monetary unification on the volatility of the extensive margin of trade. First, we highlight empirical novel facts about the effects of monetary unification. We build country-level measures of the extensive margin of intra-EMU exports and describe...

This paper analyzes jointly optimal fiscal and monetary policies in a small open economy with capital and sticky prices. We allow for trade in consumption goods under perfect international risk-sharing. We consider balanced-budget fiscal policies where authorities use distortionary taxes on...
