New Formula: Dynare 4.4.3

Dynare is a software platform for handling a wide class of economic
models, in particular dynamic stochastic general equilibrium (DSGE) and
overlapping generations (OLG) models. The models solved by Dynare
include those relying on the rational expectations hypothesis, wherein
agents form their expectations about the future in a way consistent with
the model. But Dynare is also able to handle models where expectations
are formed differently: on one extreme, models where agents perfectly
anticipate the future; on the other extreme, models where agents have
limited rationality or imperfect knowledge of the state of  the economy
and, hence, form their expectations through a learning process. In terms
of types of agents, models solved  by Dynare can incorporate consumers,
productive firms, governments, monetary authorities,  investors and
financial intermediaries. Some degree of heterogeneity can be achieved
by including several distinct classes of agents in each of the
aforementioned agent categories.
