Intertemporal shifts in conduct, such as a transition from competitive to anti-competitive behavior, induce shifts in the firms’ equilibrium price configurations. Such shifts generate non-stationary price dynamics in addition to those which originate from exogenous fundamentals. We exploit...

This paper proposes an indirect method for making empirical inference on the elasticity of substitution between capital and labor. The idea is that estimates of the elasticity may be retrievable from theory derived behavioral equations, by conducting comparative statics with respect to this...

I apply the Johansen and Swensen (1999, 2004) method of testing exact rational expectations within the cointegrated VAR (Vector Auto-Regressive) model, to testing the New Keynesian (NK) model. This method permits the testing of rational expectation systems, while allowing for non-stationary...

Ideally, early warning indicators (EWI) of banking crises should be evaluated on the basis of their performance relative to the macroprudential policy maker’s decision problem. We translate several practical aspects of this problem — such as difficulties in assessing the costs and benefits...
