Public-private partnerships (PPPs) are increasingly used to provide infrastructure services. Even though PPPs have the potential to increase efficiency and improve resource allocation, contract renegotiations have been pervasive. We show that existing accounting standards allow governments to...

Public-private partnerships (PPPs) cannot be justified because they free public funds. When PPPs are desirable because the private sector is more efficient, the contract that optimally trades demand risk, user-fee distortions and the opportunity cost of public funds is characterized by a minimum...

A principal, who wants prices to be as lowas possible, contracts with agents who would like to charge the monopoly price. The principal chooses between a Demsetz auction, which awards an exclusive contract to the agent bidding the lowest price (competition for the field) and having two agents...

It has become increasingly common to allocate highway franchises to the bidder that offers to charge the lowest toll. Often, building a highway increases the value of land held by a small group of developers, an effect that is more pronounced with lower tolls. We study the welfare implications...

Regulating seaports is difficult in general, even more so for the weak regulatory institutions common in developing countries. For this reason some countries have awarded these facilities via Demsetz auctions, to the port operator that bids the lowest cargo-handling fee. A major concern with...

In this paper we show that fixed-term contracts, which are commonly used to franchise highways, do not allocate demand risk optimally. We characterize the optimal risk sharing contract and show that it can be implemented with a fairly straightforward mechanism---an LPVR auction. Instead of...

In this paper we show that fixed-term contracts, which are commonly used to franchise highways, do not allocate demand risk optimally. We characterize the optimal risk-sharing contract and show that it can be implemented with a fairly straightforward mechanism--a least-present-value-of-revenue...

This paper reviews the Latin American experience with highway privatization during the last decade. Based on evidence from Argentina, Colombia and Chile, we find that private financing of new highways freed up fewer public resources than expected because public funds were often diverted to bail...

On theoretical grounds alone, there is no a priori reason why higher taxes should reduce the desired capital stock, since a tax increase reduces marginal returns but also increases depreciation and interest payment allowances. Using a panel of Chilean corporations, this paper estimates a...

In 2016, Brazilian construction firm Odebrecht was fined $2.6 billion by the US Department of Justice (DOJ). According to the plea agreement, between 2001 and 2016 Odebrecht paid $788 million in bribes in 10 Latin American and two African countries in more than 100 large projects. The DOJ...
