Influence of climatic factors and climate change adaptation strategies on farm productive efficiency in Kenya

The goal of this study is to support poverty reduction through assessing farm level efficiency in a changing climate and the impact of climatic factors and climate change adaptation strategies on farm productive efficiency in different parts of Kenya. The study will also propose probable policy recommendations to improve productive efficiency and climate change adaptation strategies. 


Agricultural values of the wild coffee genetic resource in Ethiopia: implication for conservation of the wild coffee forest in southwestern Ethiopia

This paper is focuses on assessing the agricultural value of wild coffee genetic resource in view of local coffee producers. Specifically, it is to estimate their demand for improved coffee planting material with respect to coffee production constraints the farmers are facing. Three sites are considered based on variability in coffee production systems. It includes the forest communities keeping wild coffee types, semi-forest coffee types, and areas where coffee production is exclusively dependent upon improved types.


Building a Forest Sector Model for China: Analysis of Domestic and International Impact of Forest Policy Change

The Objectives of this project are two folds.  One is to establish the Spatial Equilibrium Model (SEM) for China’s domestic wood product markets that links domestic and international policy changes to demand, supply and trade of forest products in China. The other is to make forecast of forest products trade (including changes in demand, supply, imports and exports) in China, triggered by potential policy changes such as the ending of the “Natural Forest Protection Program (NFPP)”, implementation of the “Collective Forest Tenure Reform” and “Sloping Land Conversion Program (SLCP)”.  China’s policy makers and international community will be better informed with policy assessment tool like this.  


Automobile demand analysis in Beijing

The overall goal of this research is to: (1) Evaluate the externality costs from transportation in terms of congestion and vehicle emissions (2) Analyze the factors that influence individual’s transportation mode choice (in vehicle time, out vehicle time, automobile ownership et al) (3) Analyze the vehicle factors that influence in individual’s vehicle purchase decision (price, fuel consumption, size et al)? We believe the case study of Beijing will yield insights more generally transferable to scholar and practitioner theories about the role of environmental policy instrument in reducing negative externality in the field of urban transportation. 


Combining state of the art science with practitioner´s wisdom in the design of PES schemes: Lessons from the Costa Rican experience

Our goal is to learn about the Costa Rican experience from the inside, working closely with FONAFIFO staff to understand how they have sought to improve efficiency and to explore  options for setting payment levels and targeting to increase efficiency, without missing the myriad of norms, rules, and other obstacles that program managers might face in the implementation of, for example, procurement auctions. 


Estimating external costs of transportation in Beijing - air pollution costs and congestion costs

This project aims at (1) Documenting  the  main  urban transportation challenges in China, public  policies in this field, and evaluating the effectiveness of these policies; (2) Improving the assessment of  transportation externality costs in China (with a focus on Beijing) based on a large scale urban household survey and a proper estimation methodology; (3) Developing an analytical and empirical framework which links private automobile ownership and behavioural transportation modal choice to enhance the understanding of individual’s travel demand choice, automobile purchase and use decisions; (4) Building capacities in China based on quantative and qualitative assessments of  decision-making process in transportation policies to reach a better understanding of alternative policy instruments for reducing negative externalities from urban transportation.


The Value of Automobile Travel Time and Its Congestion Policy Implications

The overall objective of the study is to provide the value of time estimates for automobile users on a congested road using a stated preference survey. The purpose of this study is to obtain the public preferences for time savings on a congested road, which we believe could provide important policy inputs for ongoing congestion pricing discussions in Beijing.


Understanding the tradeoffs between planned marine conservation policies and artisanal fishing in key coastal areas of Costa Rica

The projects objective is to identify local capabilities, assets, and activities that characterizes the livelihoods of small scale fishers in Costa Rica. A special attention will be given on how different regulations (external and internal) defining who, where, when, what, and how to fish might affect these livelihoods and the natural resource base.


Performance based payments for protecting turtles: understanding the conditions for its success

In one of the major nesting beaches (La Flor), the Nicaraguan government has made an effort to enforce the prohibition to harvest by defining a protected area patrolled by governmental officers, and the army. However the effectiveness of this policy is questioned, particularly because of the difficulties to exclude people from turtle’s habitat, and the scarce governmental budgets dedicated to the enforcement of these regulations. 


One-child policy in China

The objectives of this field study are: (1) to implement a set of experiments to investigate the effect of the one-child policy on; (2) to collect data of peoples’ back-ground and in particular if they were born right before or right after the policy was implemented. By implementing this experiment, it is possible to estimate the effect of the policy in a set of preferences such as cooperativeness, risk attitudes and time consistency.


Valuation and effects of the congestion charge in Beijing

This project about the congestion charge in Beijing is in three parts. Each part will look at different aspects of the congestion charge, one is on valuation of travel time, the other will analyse the effects of the congestion charge policy on different commuting modes and the experiment is on hypothetical bias and individuals stated preferences in transportation studies. 


Social Learning, Gender, and Willingness-to-pay for Solar Lanterns

This project is an attempt to better understand the effects of social networks on the diffusion and adoption of new technologies. In particular, we investigate if having friends or relative that had a chance to experience solar lanterns for their personal use increases an individual's willingness to pay for a solar lantern.


Water studies in Kenya

In Kenya we are carrying out a series of water related projects. In one project we study the Nairobi Water Company that is considering a water tariff reform. Another study is on rural water source choice and the main objective of this research is to generate information that can inform the evolution of improved water management policies in Kenya.


Managing habitat exchanges for multiple ecosystem services

Our focus in this project is on the interactions between multiple eco-services programs, e.g., between: two offsets programs aimed to lower costs for different eco-services; two payments programs to increase different eco-services; or one offsets program and one payments program that are each targeting a different eco-service.


Fairness versus efficiency – how procedural concerns affect coordination in a Volunteer’s Dilemma

This research project will study if and how procedural fairness concerns affect coordination such as in the provision on threshold public goods. The provision of such goods can be modeled as a coordination game with several, non-pareto-rankable equilibria. Without any additional mechanisms, coordination on an efficient equilibrium has proven to be difficult: Who should contribute, and how much? For example, in the case where the contribution of one individual is enough to provide the public good: Who should be the volunteer?


Do the Poor Overweigh Low Probability Events?

In this project, we implement carefully designed field experiments in urban Tanzania to investigate if poor households do overweigh low-probability events. We also investigate time preference behaviors of the same subjects.


Dishonesty behavior: a natural field experiment with Tanzanian farmers

In this project, our research question is: What is the level of dishonesty in an anonymous natural field experiment and are norms activated that reduces the level of dishonesty from any of the two treatments? We conduct a natural field experiment and the subjects are Tanzanian farmers that were interviewed on farming activities and socio-economic conditions and participated in risk and time preference experiments.


    Developing a Common Social-Ecological Systems Framework

    This project contributes to an effort to develop such a common framework, or meta-theoretical language, which can be used by scholars in a consistent fashion to facilitate such comparisons and subsequent generalization and theory-building.


      Scaling up Common-Pool Resource Theory

      This project is designed to build on previous synthetic work at the Workshop in Political Theory and Policy Analysis. It involves a group of 14 scholars collaborating to conduct a meta-analysis of cases of large-scale environmental governance to examine whether common-pool resource theories can help to explain outcomes at large scales.


      Strategic ignorance in purchasing decisions

      The aim of this project is twofold. First, by testing the theory of strategic ignorance in real purchase decisions, we analyze whether the existing lab results are transferable to everyday decisions of consumers. Second, if evidence is found in favor of strategic ignorance, it can have important implications for environmental policy because it sheds light on the efficiency of information provision to consumers by using for example eco- labels and certifications.


      A malaria project in Kenya

      The project includes two studies. One project is on possible differences in subjective and objective risks in four different zones with different malaria exposure, and whether a person´s subjective risk can explain his/her use of bed nets. The other is on the problem of resistance in malaria medication.


      Wildlife Corridors and Communities in the East and West Usambara Mountains: Toward Integrating Social and Biological Information in Conservation Policy and Priorities

      Forest fragmentation threatens biodiversity because many species cannot survive in small, disconnected patches of habitat.  Within the biodiversity hot spot of the Eastern Arc mountains, the East and West Usambara Mountains contain many species in a highly fragmented forest.  Decades of bird population data demonstrate that the forest fragments will continue to lose bird species even


      What Drives the (Non) Adoption of Agricultural Technologies? Time Preferences and Social Networks in Rural Tanzania

      The adoption of new agricultural technologies is instrumental in the process of adaptation to climate change. Yet, in eastern Africa the adoption rate have been very small. Besides institutional explanations, the recent literature has pointed out at the role of impatience we explore the relative importance of this explanation vis-à-vis an alternative explanation based on sharing pressure within social networks.  A combination of lab and field experiments will be used to address theses questions.


      Combining state of the art science with practitioners wisdom in the design of PES schemes: Lessons from the Costa Rican experience.

      The Costa Rican PSA Program is widely cited in discussions about REDD+, including as a reference on the costs of implementing PES and the challenges of generating additionality and livelihood co-benefits (poverty reduction).  As such, it is critical to document and extract lessons from the variation in payment levels and targeting criteria employed by Costa Rica´s National Forestry Fund (F


      Improving energy efficiency in Costa Rican households: the effect of pecuniary and non-pecuniary incentives in shaping the timing of consumption

      Reducing a country´s dependence on fossil fuels is central to mitigate climate change and to promote the use of cheaper energy sources. In Costa Rica most energy is generated using hydro-electrical plants, however the fact that energy consumption is lumped in peak hours forces the use of fossil fuel (mostly diesel and bunker) based electricity generation.


      Adaptation to Increase Resilience to Climate Change in Ethiopian Agriculture: Empowering Farmers to Adopt the Right Water Management Technologies for their Farms

      Climate change in Ethiopia will not only increase rainfall variability and lead to more frequent droughts and higher risk of rain generated floods, it will also continue to intensify the degradation of soil fertility that causes agricultural productivity to decline. Adaptation measures that build upon improved water management and enhance soil fertility are fundamental in boosting overall resilience to climate change in the Blue Nile Basin.
