"This paper develops a new and easily implementable necessary and sufficient condition for the exact identification of a Markov-switching structural vector autoregression (SVAR) model. The theorem applies to models with both linear and some nonlinear restrictions on the structural parameters. We...

Conventional economic policy models focus only on selected elements of the central bank balance sheet, in particular monetary liabilities and sometimes foreign reserves. The canonical model of an "independent" central bank assumes that it chooses money (or an interest rate) unconstrained by a...

Motivated by the dollarization debate in Mexico, we estimate an identified vector autoregression for the Mexican economy using monthly data from 1976 to 1997, taking into account the changes in the monetary policy regime which occurred during this period. We find that 1) exogenous shocks to...

We explore two popular approaches to empirical analysis of monetary policy: the New Keynesian and the identified vector autoregression approaches. Stylized models of private behavior coupled with simple rules describing policy behavior characterize New Keynesian work. Vector autoregressions...
