Dynamic discrete choice (DDC) models are not identified nonparametrically, but the non‐identification of models does not necessarily imply the nonidentification of counterfactuals. We derive novel results for the identification of counterfactuals i

It is known that plant height is a suitable parameter for estimating crop biomass. The aim of this study was to confirm the validity of spatial plant height data, which is derived from terrestrial laser scanning (TLS), as a non-destructive estimator

We estimate a time series model of weather shocks on English wheat yields for the early nineteenth century and use it to predict weather effects on yield levels from 1697 to 1871. This reveals that yields in the 1690s were depressed by unusually poor
