The Impact of Open Data on Public Procurement

We examine how open procurement data affect the competitiveness of award procedures and the execution of government contracts. The European Union recently made its historical procurement notices available for bulk download in a cohesive and user-friendly database. Comparing government contracts above and below EU procurement size thresholds, we find that, after the open data initiative, procurement officials are more likely to award treated contracts through open bidding. In cross-sectional analyses, we document variation in the open bidding effect consistent with two underlying mechanisms: (1) increased scrutiny by NGOs and investigative journalists and (2) learning by national procurement regulators. However, treated contracts are also more likely to experience costly modifications because the shift to open bidding introduces rigidity that limits officials’ discretion in selecting suppliers based on private information. Overall, our evidence indicates that open procurement data promote competitive bidding but lead to contracts with weaker execution performance. These inferences also hold in an alternative open data setting.     

Are the Liquidity and Collateral Roles of Asset Bubbles Different?

Several papers explain why asset bubbles are observed when growth is large. These papers differ in the role of the bubble, used to provide liquidities or as collateral in a borrowing constraint. We compare the liquidity and collateral roles of bubbles in an overlapping generations model. When the bubble is deterministic, the equilibrium is identical under these two roles, implying that the same mechanism explains the crowding-in effect of the bubble on growth. With stochastic bubbles, growth is larger when bubbles play the liquidity role, because the burst of a bubble used for liquidity is less damaging to capital investors.
