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.


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.


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.


Household forest values under varying management regimes in rural Ethiopia

Ethiopia’s forest cover is estimated at less than 4% of the total land area of about 1 million km2. The consequences of deforestation and forest degradation include reduced agricultural production and decreased household welfare. The Ethiopian government promulgated a forest proclamation and approved the first forest policy in 2007. In its recent comprehensive plan referred to as Plan for Accelerated and Sustained Development to End Poverty (PASDEP), the government also indicated its plan to increase forest cover from about 4% to 9% over a period of five years. The reality on the ground suggests that there is continuing deforestation and mismanagement of existing forests. The government has acknowledged in its forestry laws and regulations that depletion of these resources have resulted in reduced agricultural productivity and subsequently reduced quality of life of the rural people. Moreover, frequent restructuring of the main government body responsible for natural resources in general and forestry in particular meant different levels of attention paid to the sector with its implications for staffing and continuity of programs.
