Economic integration and agglomeration in a customs union in the presence of an outside region [PDF]
, 2012 New Economic Geography (NEG) models do not typically account for the presence of regions other than the ones involved in the integration process. We explore such a possibility in a Footloose Entrepreneur (FE) model aiming at studying the stability ...

MathematicsIn this paper, we use a semi-discretization method to consider the predator–prey model of Leslie type with ratio-dependent simplified Holling type IV functional response.

Bifurcation Analysis and Chaos Control in a Discrete-Time Parasite-Host Model
Discrete Dynamics in Nature and Society, 2017 A discrete-time parasite-host system with bifurcation is investigated in detail in this paper. The existence and stability of nonnegative fixed points are explored and the conditions for the existence of flip bifurcation and Neimark-Sacker bifurcation ...

Bifurcation Analysis of Homoclinic Flips at Principal Eigenvalues Resonance
Applied Mathematics, 2013 One orbit flip and two inclination flips bifurcation is considered with resonant principal eigenvalues. We introduce a local active coordinate system to establish bifurcation equation and obtain the conditions when the original homoclinic orbit is kept or broken.

Codimension-Two Bifurcations of Fixed Points in a Class of Discrete Prey-Predator Systems
Discrete Dynamics in Nature and Society, 2011 The dynamic behaviour of a Lotka-Volterra system, described by a planar map, is analytically and numerically investigated. We derive analytical conditions for stability and bifurcation of the fixed points of the system and compute analytically the normal

Critical bifurcation surfaces of 3D discrete dynamics
Discrete Dynamics in Nature and Society, 2000 This paper deals with the analytical representation of bifurcations of each 3D discrete dynamics depending on the set of bifurcation parameters. The procedure of bifurcation analysis proposed in this paper represents the 3D elaboration and specification ...

Codimension-one bifurcation analysis and chaos of a discrete prey–predator system
Journal of Taibah University for ScienceIn this paper, we explore local dynamics at equilibrium points, the existence of bifurcation sets and codimension-one bifurcation analysis of a discrete prey–predator system with Holling type-II functional response.

A simple model of a speculative housing market [PDF]
We develop a simple model of a speculative housing market in which the demand for houses is influenced by expectations about future housing prices. Guided by empirical evidence, agents rely on extrapolative and regressive forecasting rules to form their ...

Bifurcation and complex dynamics of a discrete-time predator-prey system involving group defense [PDF]
Computational Ecology and Software, 2015 In this paper, we investigate the dynamics of a discrete-time predator-prey system involving group defense. The existence and local stability of positive fixed point of the discrete dynamical system is analyzed algebraically.

Dynamic Effects of Regulation and Deregulation in Goods and Labour Markets [PDF]
Modern macroeconomic models with a Keynesian flavour usually involve nominal rigidities in wages and goods prices. A typical model is static and combines wage bargaining in the labour markets and monopolistic competition in the goods markets.
