Generating New PES Institutions and Increased Impacts in Mexico: a framed field experiment on coordination and sanctions in Matching Funds sites

Alexander Pfaff, Luz Rodriguez, Elizabeth Shapiro Draft working paper, Duke University (part of a project supported by The Tinker Foundation). While states pay landowners in the big payment-for-ecosystem-services (PES) programs, PES can be locally organized. Downstream actors, e.g., may offer incentives to upstream. Even − or especially? − with local organization, though, there may be […]

Behavioral Spillovers from Targeted Incentives: losses from excluded individuals can counter gains from those selected

Francisco Alpizar, Anna Norden, Alexander Pfaff, Juan Robalino Duke Environmental & Energy Economics Working Paper Series Incentives conditioned on socially desired acts such as donating blood, departing conflict or mitigating climate change have increased in popularity. Many incentives are targeted, excluding some of the potential participants based upon characteristics or prior actions. We hypothesize that […]

Unintended Effects of Targeting an Environmental Rebate

Francisco Alpizar, Anna Norden, Alexander Pfaff, Juan Robalino Environmental and Resource Economics (accepted) When designing schemes such as conditional cash transfers or payments for ecosystem services, the choice of whom to select and whom to exclude is critical. We incentivize and measure actual contributions to an environmental public good to ascertain whether being excluded from […]

Costa Rica’s Payment for Environmental Services Program: Intention, Implementation, and Impact

G. Arturo Sanchez-Azofeifa, Alexander Pfaff, Juan Robalino, Judson Boomhower Conservation Biology 2007 volume 21, number 5, 1165–1173 We evaluated the intention, implementation, and impact of Costa Rica’s program of payments for environmental services (PSA), which was established in the late 1990s. Payments are given to private landowners who own land in forest areas in recognition […]

Will buying tropical forest carbon benefit the poor? evidence from Costa Rica

Alexander Pfaff, Suzi Kerr, Leslie Lipper, Romina Cavatassi, Benjamin Davis, Joanna Hendy, G. Arturo Sanchez-Azofeifa Land Use Policy 24 (2007) 600–610 We review claims linking both payments for carbon and poverty to deforestation. We examine these effects empirically for Costa Rica during the late 20th century using an econometric approach that addresses the irreversibilities in […]

The Dynamics of Deforestation and the Supply of Carbon Sequestration: Illustrative Results from Costa Rica

Suzi Kerr, Alexander Pfaff, G. Arturo Sanchez-Azofeifa Central America Project, Environment: Conservation and Competitiveness. HIID 2001. Chapter 15. In this chapter we consider potential gains derived from preventing deforestation, drawing heavily from information from Chapter 14. It uses the same economic model and econometric technique and the same land use/land cover data. It also uses […]

How Can Carbon Sequestration in Tropical Forests Be Rewarded?  Evidence from Case Of Costa Rica

Suzi Kerr, Alexander Pfaff, G. Arturo Sanchez-Azofeifa, Marco Boscolo Central America Project, Environment: Conservation and Competitiveness. HIID 2001. Chapter 14. The chapter is structured as follows. First, below, we begin this analysis of the process influencing land changes with a dynamic model of land-use choices. Such models have often been suggested, but crucial features have […]

The Kyoto Protocol & Payments for Tropic

The Kyoto Protocol & Payments for Tropical Forest:  An Interdisciplinary Method for Estimating Carbon-Offset Supply and Increasing the Feasibility of a Carbon Market under the CDM

Alexander Pfaff, Suzi Kerr, R. Flint Hughes, Shuguang Liu, G. Arturo Sanchez-Azofeifa, David Schimel, Joseph Tosi, Vicente Watson Ecological Economics 35 (2000) 203–221 Protecting tropical forests under the Clean Development Mechanism (CDM) could reduce the cost of emissions limitations set in Kyoto. However, while society must soon decide whether or not to use tropical forest-based […]
