A unique feature of the financial crisis is the unprecedented collapse in global world trade. The objective of this paper is to explain some of that collapse as a move toward protectionism triggered not by nationalistic interests but by ‘competing’ objectives among trading partners from the...

The concept of formation of the equilibrium exchange rate on the conversion market was developed, taking into account foreign trade, capital flows and other components of the balance of payments. As the main determinants of theoretical-structural model of the dynamics of the exchange rate equal...

The aim of this article is to study the local and global dynamics of a general equilibrium closed economy with overlapping generations and inherited tastes (aspirations). It shows that the interaction between the intensity of aspirations and the elasticity of substitution of effective...

This paper deals with an extension of the concept of correlated strategies to Markov stopping games. The idea of this paper was presented at Game Theory and Mathematical Economics, International Conference in Memory of Jerzy Łoś (1920 - 1998), Warsaw, September 2004. The Nash equilibrium...

This paper analyses the dynamics of a two-dimensional overlapping generations model with young and old age labour supply. It is shown that the public provision of health investments, which, in turn, affects the demand for material consumption, may represent a source of local indeterminacy,...

This study analyses the dynamics of a two-dimensional overlapping generations economy with endogenous labour supply à la Reichlin (1986) and aspirations, i.e. effective consumption by individuals of the current generation depends on the standard of living (based on consumption experience) of...

I study connected manifolds and prove that a proper map f: M - M is globally invertible when it has a nonvanishing Jacobian and the fundamental group pi (M) is finite. This includes finite and infinite dimensional manifolds. Reciprocally, if pi (M) is infinite, there exist locally invertible...

This paper is to analyze Susceptible-Exposed-Infectious-Recovered (SEIR) COVID-19 pandemic model. In this article, a modified SEIR model is constructed, and is also discussed various aspects of it with mathematical analysis to study the dynamic behavior of this model. The spread of this disease...

This paper demonstrates the diverse dynamical possibilities arising out of a simple macroeconomic model of debt-financed investment-led growth in the presence of interest rate rules. We show possibilities of convergence to steady state, growth cycles around it as well as various complex...

We study the stability properties and conditions for the onset of Shilnikov chaos in the UK New Keynesian macroeconomy, as well as the shifts in the equilibrium dynamics under various policy regimes. We find that Shilnikov chaos emerges for a restricted part of the free parameters space in the...
