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...

This paper explores the dynamics of the U.S. hog market with three different dynamic models that are distinguished only by their assumptions with regard to market participants' expectations of future prices. The first model assumes that all the producers in the market have rational expectations....

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...

The chaotic dynamics of a random walker in a quenched environment is studied via the thermodynamic formalism of Ruelle, Sinai, and Bowen, in which chaotic properties are expressed in terms of a free energy-type function, ψ(β), of an inverse temperature-like parameter, β. Localization...

For studying short-range time correlations in financial signals, we have envisaged to combine the Zipf method and the i-variability diagrams (VD) as useful tools. The 2-VD describes the local curvature short-range correlations. We have resulted into ranking the 2-VD data according to their...

A display of the tentatively basic parameters of stocks, i.e. the daily closing price and the daily transaction volume is presented eliminating the time variable between them. The “phase diagram” looks like a triangular region similar to the two-phase region of traffic diagrams. The data is...

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...

The volatile movements in commodity prices during the last years have raised new questions to be discussed in both policy and academic spheres. Up to the financial slump of the second quarter of 2008 commodity prices grew fast for several consecutive years in a highly volatile context. The...
