Dear all,
I would like to estimate the following model:
i have n firms, each firm has a bundle of 3 products, characterized by the different resource allocation for each product, measured in % which sums up to 100%.
That is, e.g. firm 1 has 20% of production devoted to product 1, 30% to product 2, etc., 100% in total.
I would like to explain the resource allocation choice by a firm. Thus, the dependent variable is actually 3 variables, which are continuous variables (% of resources) and are interdependent.
Which econometric model should I use and how to handle this in stata?
Thanks very much in advance,
Regards,
Elena
