This paper provides an overview of the panel VAR models used in macroeconomics and finance. It discusses what are their distinctive features, what they are used for, and how they can be derived from economic theory. It also describes how they are estimated and how shock identification is...

In this paper we attempt to evaluate the quantitative impact of financial shocks on key indicators of real activity and financial conditions. We focus on financial shocks as they have received wide attention in the recent literature and in the policy debate after the global financial crisis. We...

The elasticity of substitution between capital and labor and, in turn, the direction of technical change are critical parameters in many fields of economics. Until recently, though, the application of production functions with non-unitary substitution elasticities (i.e., non Cobb Douglas) was...

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...

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...

Despite being critical parameters in many economic fields, the received wisdom, in theoretical and empirical literatures, states that joint identification of the elasticity of capital-labor substitution and technical bias is infeasible. This paper challenges that pessimistic interpretation....

The paper analyses the effect of equity price shocks on current account positions for the G7 industrialized countries in 1974-2007. It uses a Bayesian VAR with sign restrictions for the identification of asset price shocks and to test empirically for their effect on current accounts. Such shocks...
