ABSTRACT
Some field experiments in comparative politics are designed to test hypotheses derived from social science theories, and are created and implemented entirely by researchers. Other field experiments explore the effects of existing interventions undertaken by non-academic organizations, such as Intergovernmental Organizations (IOs), Non-Governmental Organizations (NGOs), or government bodies. These interventions may be intended to reduce poverty, boost political participation, encourage development, promote democracy, or curb the spread of disease. The interventions may be well designed, have positive effects, and be cost effective. They may also have unintended consequences, adverse effects, or no effects whatsoever. Determining the effects of these interventions is important for public policy, intellectually rewarding, and socially desirable.
