Giammarioli, Nicola - 2003

This paper investigates a dynamic general equilibrium model with search. In particular, search externalities are reßected by an increasing returns to scale matching function, which may imply an indeterminate equilibrium. Hence, the model is capable to generate business ßuctuations, driven by...

Inflation targets and the liquidity trap

Klaeffling, Matt; Perez, Victor Lopez - 2003

The presence of a lower bound of zero on nominal interest rates has important implications for the conduct of optimal monetary policy. Standard rational expectations models can have alternative steady states as well as non-unique laws of motion, i.e. there can be possible sunspot equilibria....

Interpreting implied risk-neutral densities

Hördahl, Peter; Vestin, David - 2003

This paper examine differences between risk-neutral and objective probability densities of future interest rates. The identification and quantification of these differences are important when risk-neutral densities (RNDs), such as option-implied RNDs, are used as indicators of actual beliefs of...

Measuring contagion with a Bayesian, time-varying coefficient model

Ciccarelli, Matteo; Rebucci, Alessandro - 2003

To measure contagion empirically, we propose using a Bayesian time-varying coeﬃcient model estimated with Markov ChainMonte Carlo methods. The proposed measure works in the joint presence of heteroskedasticity and omitted variables and does not require knowledge of the timing of the crisis. It...

Indeterminacy of rational expectations equilibria in sequential financial markets

Donati, Paola - 2003

We provide a general characterization of the structure of rational expectations equilibria of any degree of revelation for pure exchange, sequential economies, with deffinitely many states of private information, an incomplete financial market and nominal assets. We estimate the dimension of the...

Aggregation-theoretic monetary aggregation over the euro area, when countries are heterogeneous

Barnett, William A. - 2003

We derive fundamental new theory for measuring monetary service flows aggregated over countries within the European … aggregation over countries. Our theory permits monitoring the effects of policy at the aggregate level over the euro area, while … simultaneous use of two inflation indexes over the euro area. …

Implicit tax co-ordination under repeated policy interactions

Catenaro, Marco; Vidal, Jean-Pierre - 2003

In the context of a stylised game theoretical framework of capital tax competition, we show that when repeated policy interactions are associated to a systematic punishment of the deviating policymaker, a co-ordinated outcome can be the solution to the non co-operative tax game. This result...

Interpolation and backdating with a large information set

Angelini, Elena; Henry, Jérôme; Marcellino, Massimiliano - 2003

Existing methods for data interpolation or backdating are either univariate or based on a very limited number of series, due to data and computing constraints that were binding until the recent past. Nowadays large datasets are readily available, and models with hundreds of parameters are fastly...

Persistence, the transmission mechanism and robust monetary policy

Angeloni, Ignazio; Coenen, Günter; Smets, Frank - 2003

In this paper we first explore the impact of nominal and real persistence on the transmission process of various shocks in an estimated DSGE model of euro area. We then analyse its impact on optimal monetary policy and investigate the performance of various monetary policies when the policy...
