Oct 04, 2020 · The dynamic formulation of the Walrasian assumption is. dp dt = f D p − S p, f 0 = 0, f ′ 0 > 0. Retaining the first order term in a Taylor series expansion near the equilibrium, p ∗, we obtain the following linear differential equation. dp dt = a 0 dD dp − dS dp p ∗ p − p ∗, with solution for an initial price, p 0.

The study of differential equations is a wide field in pure and applied mathematics, physics, and engineering. All of these disciplines are concerned with the properties of differential equations of various types. Pure mathematics focuses on the existence and uniqueness of solutions, while applied mathematics emphasizes the rigorous justification of the methods for approximating solutions. Differential equations play an important role in modeling virtually every physical, tech…

modem theory of differential equations. A differential equation expresses the rate of change of the current state as a function of the current state. A simple illustration of this type of dependence is changes of the Gross Domestic Product (GDP) over time. Consider state x of the GDP of the economy. The rate of change of the GDP is proportional to the current GDP x(t) = gx(t),
