Stata code to estimate import elasticities (Hybrid Code)http://web.ics.purdue.edu/~asoderbe/PublishCode/HybridCode.zipElasticities_files/HybridCode.zipshapeimage_1_link_0

The following import demand and supply elasticities are produced using the hybrid Feenstra (1994) / Broda & Weinstein (2006) methodology described in Soderbery (2014).  The following estimates are generated using US import data over the period 1993-2007.  The code is written in a general form that allows users to easily adapt the estimator to their data.  One point to note for those using the estimates directly.  I have imposed the constraint that ρ< (σ-1)/σ ex postThis constraint is violated around 10% of the time by the actual estimates of θ1 and θ2, and can be overcome by recalculating ρ.
