摘要

本文讨论了考虑动态记忆效应的恒速经济增长模型的推广。记忆是指给定时间内的内生变量或外生变量不仅取决于它们当时的值,还取决于它们之前的值。为了描述动态存储器,我们使用非整数阶导数。我们得到了具有非积分阶导数的分数阶微分方程的解,它描述了净投资变化和幂律衰落记忆效应引起的输出动态。

Economic Growth Model with Constant Pace and Dynamic Memory
The article discusses a generalization of model of economic growth with constant pace, which takes into account the effects of dynamic memory. Memory means that endogenous or exogenous variable at a given time depends not only on their value at that time, but also on their values at previous times. To describe the dynamic memory we use derivatives of non-integer orders. We obtain the solutions of fractional differential equations with derivatives of non-integral order, which describe the dynamics of the output caused by the changes of the net investments and effects of power-law fading memory.
