This paper studies how household inequality shapes the effects of the zero lower bound (ZLB) on nominal interest rates on aggregate dynamics. To do so, we consider a heterogeneous agent New Keynesian (HANK) model with an occasionally binding ZLB and solve for its fully non-linear stochastic...

This manuscript analyzes the fundamental factors that govern the qualitative behavior of discrete dynamical systems. It introduces methods of analysis for stability analysis of discrete dynamical systems. The analysis focuses initially on the derivation of basic propositions about the factors...

The standardised residuals from GARCH models fitted to three stock indices of the Athens Stock Exchange are examined for evidence of chaotic behaviour. In each case the correlation dimension is calculated for a range of embedding dimensions. The results do not support the hypothesis of chaotic...

A model of cumulative causation is extended to incorporate endogenous structural change. This is achieved via the use of a non-linear feedback of the growth rate on to the income elasticity of demand for exports. The result is a model that, under certain conditions, exhibits chaotic switches...

This article examines the dynamic relationship between two key US money market interest rates – the federal funds rate and the 3-month Treasury bill rate. Using daily data over the period from 1974-99, we find a long-run relationship between these two rates that is remarkably stable across...

This Paper challenges the consensus on the nature of unemployment dynamics in Britain. We show that the argument that changes in unemployment arise mostly from changes in the duration of unemployment (rather than in the event of becoming unemployed) is flawed. In fact, while shocks to the...

Recent theoretical advances in consumption theory suggest that there may exist predictable consumption surges which, if not taken sufficiently into account in forecasting, may lead to predictable forecast errors. We use this insight to identify economic variables that might help improve the...

Business cycles tend to comove across countries. However, standard models that attribute comovement to propagation of exogenous shocks struggle to generate a level of co-movement that is as high as in the data. In this paper, we consider models that produce business cycles endogenously, through...

This paper studies how household inequality shapes the effects of the zero lower bound (ZLB) on nominal interest rates on aggregate dynamics. To do so, we consider a heterogeneous agent New Keynesian (HANK) model with an occasionally binding ZLB and solve for its fully nonlinear stochastic...

This paper explores the dynamics of market selection for an industry in which firms employ relatively simple pricing, production and investment routines and in which consumers switch between rival firms in response to price differentials but do not all do so instantaneously. The key issue is...
