“…The equilibrium constraint forces the agents expectations to match the corresponding equilibrium probabilities. This equilibrium constraint can complicate the evaluation of the likelihood function since, absent a clear selection rule, the direct nested …xed point approach (Rust, 1987) to satisfying this constraint will be mis-speci…ed if there is more than one …xed point (see Su and Judd, 2007). Finally, we note that even with an equilibrium selection rule in place, maximizing the constrained likelihood is a numerically challenging task.…”

“…In this paper, we use Mathematical Programming with Equilibrium Constraints (MPEC) (Su and Judd, 2008) to estimate the BLP model because it is faster and more robust than NFP. MPEC relies on a modern, state of the art solver such as KNITRO or SNOPT, to solve the model in one optimization step using constraints:…”

“…In practice, to estimate the model we reformulate the minimization problem as a mathematical programming problem with equilibrium constraints (MPEC), as described by Su and Judd (2012). 22 The advantage of this method is to allow the program to search for the minimum without requiring that at each iteration all equilibrium conditions are exactly satisfied.…”
