Description

Provides estimation methods for markets in equilibrium and disequilibrium. Specifically, it supports the estimation of an equilibrium and four disequilibrium models with both correlated and independent shocks. It also provides post-estimation analysis tools, such as aggregation and marginal effects calculations. The estimation methods are based on full information maximum likelihood techniques given in Maddala and Nelson (1974) (doi:10.2307/1914215). They are implemented using the analytic derivative expressions calculated in Karapanagiotis (2020) (doi:10.2139/ssrn.3525622). The equilibrium estimation constitutes a special case of a system of simultaneous equations. The disequilibrium models, instead, replace the market clearing condition with a short side rule and allow for different specifications of price dynamics.

Description

The code implements a simple version of the radial attention model and solves it. The solver is based on a concurrent re-formulation of the value function iteration algorithm. Further, it uses an adaptive search grid implementation to provide more accurate optimal control approximations. For more implementation details see the documentation.
