Seminar abstract

Many empirical studies estimate impulse response functions that depend on the state of the economy. Most of these studies rely on a variant of the local projection (LP) approach to estimate the state-dependent impulse response functions. Despite its widespread application, the asymptotic validity of the LP approach to estimating state-dependent impulse responses has not been established to date. We formally derive this result for a structural state-dependent vector autoregressive process. The model only requires the structural shock of interest to be identified. A sufficient condition for the consistency of the state-dependent LP estimator of the response function is that the first- and second-order conditional moments of the structural shocks are independent of current and future states, given the information available at the time the shock is realized. This rules out models in which the state of the economy is a function of current or future realizations of the outcome variable of interest, as is often the case in applied work. Even when the state is a function of past values of this variable only, consistency may hold only at short horizons.

Speaker bio

Professor Elena Pesavento

Elena Pesavento is an Associate Professor in the Department of Economics at Emory University. Her specialty is Time Series Analysis with focus on inference and testing in Vector Autoregressive Models. In particular, she studies inference when variables are non-stationary (in the presence of unit roots, cointegration or structural breaks) or persistent (local to unity). Her more recent focuses on the analysis of non-linear models with particular interest in identification and estimation of impulse response functions in non-linear VARs
