Understanding unethical behavior is essential to many phenomena in the real world. We carry out a field experiment in a unique setting that varies the levels of reciprocity and guilt in an ethical decision. A survey more than one year before the field experiment allows us to compare at the individual level stated unethical behavior with revealed behavior in the same situation in the field. Our results indicate a strong discrepancy between stated and revealed behavior, regardless of the specific treatment in the field experiment.

The rapid growth in Tree Planting for Fuelwood (TPF) program indicates the importance of taking care of the increasing demand for fuelwood globally. TPF programs in Tanzania aim to sustainably meet the rising demand for fuelwood. We evaluate the impact of TPF programs on the number of trees planted and those planted for fuelwood. Using survey data, we employ the Heckman and Propensity Score Matching techniques to estimate whether households plant trees for fuelwood and can identify tree species that would influence them to plant trees.
