Experiments and Behavior


My crop science background taught me experimental design back in the 1980s and my PhD work on farming systems and the potetial of agroforestry Technologies in Zambia utilized both on station and on farm experimental data. My work on preferences using experiments started back in the 1990s and includes studies of risk preferences and time preferences of poor rural households in Ethiopia, Indonesia and Zambia. The research has aimed at assessing how these preferences are related to the level of poverty of households as well as some of the behavioural consequences of their preferences. Such behavioural consequences may also have important policy implications and may provide a basis for interventions on poverty, equity or environmental grounds. For example:


  • Are poor households mining their natural resource base because they are too poor and myopic to be able to conserve it?
  • Can smart interventions be designed to reduce welfare losses due to time inconsistent behavior?
  • Can smart safety nets be provided that can protect poor households from falling into poverty traps?
  • Can smart subsidy programs be designed that can help poor households climb out of poverty and achieve higher welfare levels?
  • How can experiments be used to learn more about how people adapt to climate change

My recent work includes

  • Experiments to assess intrahousehold collaboration, gender balance in decision-making, generosity and intra-household cooperation in the project "Joint land certification: Towards Empowerment or Marginalization?" funded by the Research Council of Norway and in studies of youth livelihood opportunities in Ethiopia (With Sosina Bezu)
  • Experiments to assess how climate risk and shocks affect technology adoption and whether EU theory or Prospect Theory is more appropriate to predict behavior
  • Experiments to assess input demand in agriculture that introduces larger exogenous price variation than what can be found in survey data
  • Experiments with youth to assess whether generosity and trust among youth differs depending on social distance on socio-economic background and context.
  • Experiments With Youth Business Groups to assess how behavioral characteristics are related to performance and outcomes for individuals and groups
