We use high-frequency intraday interest rate data to measure euro area monetary policy shocks on the days of ECB interest rate announcements between 2002 and 2013. In line with Gürkaynak et al. (2005), we look at monetary policy shocks along two time dimensions: one related to the current level...

Several recent papers are devoted to the examination of the central banker's behaviour in an uncertain economic environment. This paper proposes, from a central banker's point of view, a synthesis of the main sources of uncertainty as well as an illustration of their effects within an analytical...

This paper designs, for a broad class of rational-expectations dynamic stochastic general-equilibrium models, interest-rate rules which not only ensure the local determinacy of the targeted equilibrium within the neighbourhood of the targeted steady state, but also prevent the economy from...

This paper examines whether reputation concerns can induce the central bank to implement the time-inconsistent optimal monetary policy in a standard New Keynesian model. The forward-looking nature of this model is in this respect interesting on two accounts: first, it worsens the...

We assess the long-term economic impact of the new regulatory standards (the Basel III reform), answering the following questions. (1) What is the impact of the reform on long-term economic performance? (2) What is the impact of the reform on economic fluctuations? (3) What is the impact of the...

The marginal cost of aggregate fluctuations has a term structure that is a simple transformation of the term structures of equity and interest rates. I extract evidence from index option markets to infer a downward-sloping, volatile and procyclical term structure of welfare costs. On average,...

The paper characterizes the optimal tax scheme in an open economy with structural inefficiencies on the labor market and on government size. On analytical grounds first, we show that the economy can use fiscal revaluation to exploit the terms of trade externality and to dampen the impact of an...

The unprecedented tax hikes implemented in Greece in 2010 generated a much lower than expected increase in tax revenues. In this paper, we document a new stylized fact explaining this gap: the strong increase of tax evasion. We then analyze the response of the economy to tax hikes in a stylized...

This paper examines issues related to the estimation of the government spending multiplier (GSM) in a Dynamic Stochastic General Equilibrium context. We stress a potential source of bias in the GSM arising from the combination of Edgeworth complementarity/substitutability between private...

In this paper we assess the impact of commodity price volatility on tax revenues, while existing works were concentrated on its effect on economic growth. Our empirical analysis is carried out on 80 developing countries over 1980-2008. We compute country-specific indices which measure the...
