Analyse the estimation outputs (1)-(4) to explain which one is
your preferred specification; explain your choice by comparing the
statistical characteristics of these models as well as their
economic interpretation; comment on what other test(s) could be
performed further that would help in improving the reliability of
models’ estimation.
The data are from randomly selected 230 wineries. Four following
regression models have been estimated sequentially. That is, model
(1) had been estimated first; then, after inspecting its estimates,
model (2) was estimated next and so on.
