the present work is aimed to find a new and efficient type of antioxidants for polypropylene. hence, effects of 3,3-bis(4-hydroxy-2-methyl-5-propan-2-ylphenyl)-2-benzofuran-1-one, generally known as thymolphthalein, on thermo-oxidative stability of polypropylene in solid and melt states were evaluated and compared with those of songnox 1010, an efficient commercially used antioxidant for the po...

In this paper, we investigate the impact of government’s stabilization policy on the dynamic behavior of the economic system in an analytical framework of a Keynes-Goodwin model of the growth cycle. In particular, we study the effects of the policy lag on macroeconomic stability analytically and numerically. It is shown that the increase of the policy lag contributes to destabilize the system, ...

In this paper we investigate a stochastic model for an economic game. To describe this model we have used a Wiener process, as the noise has a stabilization effect. The dynamics are studied in terms of stochastic stability in the stationary state, by constructing the Lyapunov exponent, depending on the parameters that describe the model. Also, the Lyapunov function is determined in order to ana...

In this paper we study macroeconomic stabilization in the Economic and Monetary Union (EMU) using a dynamic game approach. With the aid of a stylized macroeconomic model, this paper analyzes the transmission and interaction of national fiscal policies and monetary policy of the European Central Bank (ECB) in the EMU. A special focus is on the effects of labor market institutions in the particip...

We consider a continuous time system influenced by different agents who adopt moving horizon control. The well known Nash equilibrium concept is used to define two solution concepts fitting in the moving horizon structure. One of them is analyzed in more detail in the class of linear quadratic games. The (dis)advantages of moving horizon control are illustrated by means of a government debt sta...

In this paper we investigate a stochastic model for an economic game. To describe this model we have used a Wiener process, as the noise has a stabilization effect. The dynamics are studied in terms of stochastic stability in the stationary state, by constructing the Lyapunov exponent, depending on the parameters that describe the model. The numerical simulation that we did justifies the theore...

Net primary production (NPP) is an important metric of the global carbon cycle, critical for monitoring climate stabilization and societal economic products. Global NPP should be monitored continuously to adapt policy emerging declines.
