Demand aggregation and credit risk effects in pooled procurement: evidence from the Brazilian public purchases of pharmaceuticals and medical supplies

Pooled procurement has an important role in reducing acquisition prices of goods. A pool of buyers, which aggregates demand for its members, increases bargaining power and allows suppliers to achieve economies of scale and scope in the production. Such aggregation demand e ect lowers prices paid for buyers. However, when a buyer with a good reputation for paying suppliers in a timely manner is joined in the pool by a buyer with bad reputation may have its price paid increased due to the credit risk e ect on prices. This will happen because prices paid in a pooled procurement should refect the (higher) average buyers' credit risk. Using a data set on Brazilian public purchases of pharmaceuticals and medical supplies, we nd evidence supporting both e ects. We show that the prices paid by public bodies in Brazil are lower when they buy through pooled procurement than individually. On the other hand, federal agencies (i.e. good buyers) pay higher prices for products when they are joined by state agencies (i.e. bad buyers) in a pool. Such evidence suggests that pooled procurement should be carefully designed to avoid that prices paid increase for its members.

Desenvolvimento sustentável e turismo: o caso lençóis maranheses

Tourism as an example of alternative for sustainable development in the Lençóis Maranhenses. The objective of this work is to analyze the prospects for sustainable development in tourism in the aforementioned region. An attempt is made to evaluate the five dimensions of sustainable - ecological, economic, social, space and cultural. The base for discussion is the information gathered from the people who actually live in the region. A type of the case study was built up. The research involved speaking with the people about the viability of tourism projects, not only with an eye on economic success, job creation and income for the region. There was also an attempt to tackle the issue of social and environment impact. Data was collected through verbal contact. A variety of people were interviewed, locals, businessmen, authorities, civil representatives and they spoke about the advantages and disadvantages of tourism as the saw it and as it affected them. Their answers and comments constitute the knowledge gleaned. The development of possible new strategies is the result of this work. Strategies that should be investigated by the local government/public administration. One such strategy would involve strengthening ties whit society and hoping that the improved dialogue would encourage sustainability. Another would mean improving interdepartmental contact to streamline the performance of public bodies so that development can be better planned and non-destructive.

Generic-branded drug competition and the price for pharmaceuticals in procurement auctions

This paper studies the effects of generic drug’s entry on bidding behavior of drug suppliers in procurement auctions for pharmaceuticals, and the consequences on procurer’s price paid for drugs. Using an unique data set on procurement auctions for off-patent drugs organized by Brazilian public bodies, we surprisingly find no statistically difference between bids and prices paid for generic and branded drugs. On the other hand, some branded drug suppliers leave auctions in which there exists a supplier of generics, whereas the remaining ones lower their bidding price. These findings explain why we find that the presence of any supplier of generic drugs in a procurement auction reduces the price paid for pharmaceuticals by 7 percent. To overcome potential estimation bias due to generic’s entry endogeneity, we exploit variation in the number of days between drug’s patent expiration date and the tendering session. The two-stage estimations document the same pattern as the generalized least square estimations find. This evidence indicates that generic competition affects branded supplier’s behavior in public procurement auctions differently from other markets.
