After decades using monetary aggregates as the main instrument of monetary policy and having different varieties of crawling peg exchange rate regimes, Colombia adopted a full-fledged inflation-targeting (IT) regime in 1999, with inflation as the nominal anchor, a floating exchange rate, and the...

This paper studies the national welfare maximizing inflation tax in an open economy with imperfect competition. It shows that the presence of a monopolistic distortion dampens the incentive to engage in strategic use of the inflation tax. If this dampening effect is strong enough, monetary...

This paper develops a monetary endogenous growth overlapping generations model characterized by endogenous longevity and an inflation targeting monetary authority, and analyzes the growth dynamics that emerges from this framework. Besides the endogenous longevity which depends on the...

This paper compares different implementations of monetary policy in a new-Keynesian setting. We can show that a shift from Ramsey optimal policy under short-term commitment (based on a negative feedback mechanism) to a Taylor rule (based on a positive feedback mechanism) corresponds to a Hopf...

n this study, we examine the evolution of the Central Bank of Nigeria's (CBN) reaction function since the adoption of the structural Adjustment Programme (SAP). We consider the role of structural breaks in the reaction function, the leading composition, as well as the driving factors behind...

We propose behavioral learning equilibria, where boundedly rational agents learn to use a simple univariate linear forecasting rule with correctly specified unconditional mean and first-order autocorrelation. In the long run, agents learn the best univariate linear forecasting rule, without...

The notion of optimized rational behavior in the formation of expectations is used in this note to study the dynamics of a simple macroeconomic model. In a setting where departures from stability are not possible under perfect foresight, the selection of an optimal degree of rationality may lead...

This paper models expectation formation by taking into account that agents may produce heterogeneous expectations because of informational frictions and differing levels of a capacity to process information. We show that there are two general classes of steady states within this framework: those...
