A Climate-Economy Model with Endogenous Carbon Intensity,and without climate mitigation actions. Carbon emissions produced by the global economy cause global mean temperature rise that, in its turn, leads in the proposed modelling framework to increasing depreciation rate of physical capital slowing down or even reverting the economic growth. In a particu

A Regulated Market Under Sanctions. On Tail Dependence Between Oil, Gold, and Tehran Stock Exchangear statistical evidence of that the structure of investment portfolios on a regulated market should be adjusted to the price of gold. Our finding suggests that the active bartering of oil for goods would prevent collapsing the national market facing the international sanctions.

Dynamics of Water-Constrained Economies Affected by Climate Change: Nonlinear and Stochastic Effectd in growing frequency and severity of droughts. As a basis, we use a family of deterministic economic models that include the AK model, the Solow–Swan model, as well as linear and nonlinear versions of the Structural Dynamic Economic Model (SDEM). We then include in the modelling scheme drought dam

Solving Nonlinear Variable-Order Time Fractional Convection-Diffusion Equation with Generalized Pol fixed-order nonlinear time fractional convection-diffusion equation. The VO time fractional derivative is described in the Caputo type leading to an optimization method for the NV-TFCDE. The proposed approach is based on a new class of basis functions, namely the generalized polynomials (GP). The s

,Solvability in the Sense of Sequences for Some Non-Fredholm Operators with Drift,their right sides yields the existence and the convergence in . of the solutions. The problems involve second order differential operators with or without Fredholm property, on the whole real line or on a finite interval with periodic boundary conditions. We show that the drift term involved in thes
