This paper investigates the existence of the bank-lending channel in the transmission of monetary policy using Portuguese micro bank data. In contrast to the conventional approach, which addresses the identification issue by resorting to reduced form equations for bank credit with variables in...

We use a structural VAR with sign restrictions to jointly identify the impact of monetary policy, private absorption, technology and oil price shocks on current account fluctuations in the U.S.. We derive the sign restrictions from theoretical impulse response functions of a DSGE model with oil,...

We investigate identifiability issues in DSGE models and their consequences for parameter estimation and model evaluation when the objective function measures the distance between estimated and model impulse responses. We show that observational equivalence, partial and weak identification...

This paper estimates the effects of technology shocks in VAR models of the U.S., identified by imposing restrictions on the sign of impulse responses. These restrictions are consistent with the implications of a popular class of DSGE models, with both real and nominal frictions, and with...

This paper shows how large-dimensional dynamic factor models are suitable for structural analysis. We establish sufficient conditions for identification of the structural shocks and the associated impulse response functions. In particular, we argue that, if the data follow an approximate factor...

This paper analyses the empirical relationship between fiscal policy and the current account of the balance of payments and considers how Ricardian equivalence changes this relationship. To do so, we estimate a dynamic panel threshold model for 22 industrialised countries in which the...

New Keynesian Phillips Curves (NKPC) have been exten-sively used in the analysis of monetary policy, but yet there are a number of issues of concern about how they are estimated and then related to the underlying macro-economic theory. The first is whether such equations are identified. To check...

This paper proposes a new approach to identifying the effects of monetary policy shocks in an international vector autoregression. Using high-frequency data on the prices of eurodollar contracts, we measure the impact of the surprise component of the FOMC-day Federal Reserve policy decision on...

In this paper, we take a systematic look at global imbalances. First, we provide a definition of the phenomenon, and relate global imbalances to widening external positions of systemically important economies that reflect distortions or entail risks for the global economy. Second, we provide an...

The empirical literature using vector autoregressive models to assess the effects of fiscal policy shocks strongly disagrees on even the qualitative response of key macroeconomic variables to government spending and tax shocks. We provide new evidence for the U.S. over the period 1955-2006. We...
