Chaotic Interest Rate Rules∗ (PRELIMINARY)
نویسندگان
چکیده
A growing empirical and theoretical literature argues in favor of specifying monetary policy in the form of Taylor-type interest rate feedback rules. That is, rules whereby the nominal interest rate is set as an increasing function of inflation with a slope greater than one around an intended inflation target. This paper shows that because of the zero bound on nominal interest rates, such rules can easily lead to chaotic dynamics. The result is obtained in the context of standard and well-calibrated monetary environments. Furthermore, the battery of fiscal policies that have recently been advocated for avoiding liquidity traps are shown to be unlikely to provide a remedy for the kind of dynamics characterized in this paper. JEL Classification Numbers: E52, E31, E63.

متن کاملSuggested Rules for Designing Secure Communication Systems Utilizing Chaotic Lasers: A Survey
Chaotic communications based on semiconductor lasers have aroused great research interest since 1990s. Physical-layer encryption using chaotic lasers is an alternative to transmit message rapidly and confidentially. There are some practical devices and setups for optical chaotic communications, which are intuitively considered to be secure. However, there is lack of a set of security evaluation...
متن کاملRiver Discharge Time Series Prediction by Chaos Theory
The application of chaos theory in hydrology has been gaining considerable interest in recent years.Based on the chaos theory, the random seemingly series can be attributed to deterministic rules. Thedynamic structures of the seemingly complex processes, such as river flow variations, might be betterunderstood using nonlinear deterministic chaotic models than the stochastic ones. In this paper,...
متن کاملEnhanced superbanana transport caused by chaotic scattering across an asymmetric separatrix
Abstract This paper discusses a novel “chaotic” form of superbanana transport, and compares theory to experiments on nonneutral plasmas. Superbanana transport is caused by particles that cross local trapping separatrices (magnetic or electric ripples) in the presence of field “errors” such as toroidal magnetic curvature. Traditionally, collisions (at rate ν) cause separatrix crossings, with res...
متن کاملسرعت مجاز سیاست بهینه پولی در اقتصاد ایران
The commitment and forward-looking behavior of central bank is of great importance. Commitment imposes less social costs on the central bank and the public. However, while there is wide agreement on the importance of commitment, there is much less consensus on how to implement commitment through targeting or instrumental rules. In this paper, we have estimated a basic New Keynesian model in I...
