Following the open data initiative, procurement prices decrease and EU government agencies are more likely to award contracts to the lowest bidder.
However, the increased competition comes at a cost ─ firms execute government contracts with more delays and ex-post price renegotiations. These effects are stronger for new vendors, complex procurement projects, and contracts awarded solely based on price. Overall, our results suggest that open procurement data facilitates competition and lowers ex-ante procurement prices but does not necessarily increase allocative efficiency in government contracting."A vrai dire je ne suis pas surpris : cela semble est en partie du d'après les auteurs à la tendance à privilégier les procédures "sans risques" du type appels d'offres aux procédures plus difficiles à mener du type procédures négociées.
