The primary goal of these introductory notes is to promote the clear presentation and rigorous analysis of dynamic economic models, whether expressed in equation or agent-based form. A secondary goal is to promote the use of state-space modeling with its respect for historical process, for cause leading to effect without top-down imposition of global constraints. If economic modelers truly wish to respect the rationality of decision-makers, they should have the courage of their convictions; they should not be doing for their modeled decision-makers what in reality these decision-makers must do for themselves. These notes on dynamic economic modeling are designed for self-study by graduate students of economics. The focus is on general presentation and analysis principles for dynamic economic models expressible by means of state space models in initial value form.The state of a modeled system at any given time is a characterization of system aspects deemed by the modeler to be relevant for a speci ed purpose. Typically the only aspects 1 explicitly included in the state are aspects that can change over time; xed aspects are suppressed for ease of notation. For an economic system, the state typically includes the asset holdings, information, and beliefs of economic entities such as rms, consumers, and government policy makers.Hereafter, state space model will refer exclusively to a state space model in initial value form, that is, to a model that speci es how the state of a system changes over time, starting from a given state at an initial time t 0 [Aström and Murray, 2008, Ch. 2]. Roughly described, given any time t ≥ t 0 and time increment ∆t > 0, the state realized at time t + ∆t is postulated to be a function of the state realized at time t together with all inputs to the system between t and t + ∆t, where the inputs can include controls and random event realizations.These functional relationships are conditioned on exogenously speci ed functional forms and parameter values.
