Inference of Firm-Firm Competing Networks in the Portuguese Public Procurement Market
| Resumo: | This work explores the Portuguese public procurement landscape by developing two Firm-Firm networks − one for open tenders (competitive procedure) and other for direct awards (non-competitive procedure). Using data from the official Portuguese public procurement platform, it explores and access these two different procedures and accounts for their differences when building and analyzing the networks. Results show that half of the firms involved in direct awards also participate in open tenders and their level of product and geographical specialization is slightly higher. |
