Das LaForeT Projekt (Landscape Forestry in the Tropics) wurde vom Thünen-Institut für Waldwirtschaft in enger Zusammenarbeit mit Partnern in Ecuador, den Philippinen und Sambia in den Jahren 2016 bis 2023 durchgeführt. Das Projekt analysiert Auswirkungen von Politikinstrumenten auf die...

We study the effects of a country’s propensity to renegotiate transportation infrastructure contracts on the technical efficiency of the firms they attract. Firms are characterized by their ability to lobby and by their technical efficiency. In equilibrium, countries with a higher propensity...

We formalize the notion that GATT exceptions such as antidumping and escape clause actions can act as insurance for import competing sectors affected by adverse price shocks. We use a general equilibrium model with several import competing sectors and assume incomplete markets so that 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...

A growing number of roads are currently financed by the private sector via Build-Operate-and -Transfer (BOT) schemes. When the franchised road has no close substitute, the government must regulate tolls. Yet when there are many ways of getting from one point to another, regulation may be avoided...

In recent years several countries have started massive highway franchising programs auctioned to private firms. In these auctions, the regulator typically sets the franchise term and firms bid on tolls, or, alternatively, the regulator sets tolls and the winner is the firm that asks for the...

There are many industries in which potentially competitive segments require services provided by natural monopoly bottlenecks (essential facilities). Since it is difficult to regulate these facilities, developing countries are using Demsetz auctions, where the facility is awarded to the firm...

In many circumstances, a principal, who wants prices to be as low as possible, must contract with agents who would like to charge the monopoly price. This paper compares a Demsetz auction, which awards an exclusive contract to the agent bidding the lowest price (competition for the field) with...
