We study how temporary provision of an agricultural innovation at zero cost affects long‐run demand for that innovation. Our experimental design enables us to distinguish between an “anchoring effect” of subsidies and a “learning effect.” We document large and persistent anchoring and learning effects. For the innovation that we consider, an integrated pest management (IPM) package for Ethiopian smallholder farmers, the learning effect dominates the anchoring effect, so temporary subsidized provision promotes long‐run technology diffusion.

The presence of monitoring institutions affects quality and effort of leaders. We investigate the effect of intensified monitoring on the ability and effort of leaders for a sample of forest user groups in Ethiopia, and find experimental and non-experimental evidence of an important trade-off: monitoring increases leaders' effort but lowers their quality in terms of education and experience. This effort–ability trade-off only occurs in the presence of alternative income opportunities (affecting the opportunity cost of time) and only among a subsample of leaders with low prosocial motivation. For our context, we document that the net effect of monitoring on economic outcomes is positive.

We study the impact of endowments and expectations on reference point formation and measure the value of food safety certification in the context of fish trading on real markets in Nigeria. In our field experiment, consumers can trade a known food item for a novel food item that is superior in terms of food safety––or vice versa. Endowments matter for reference point formation, but we also document a reverse endowment effect for a subsample of respondents. The effect of expectations about future ownership is weak and mixed. While expectations seem to affect bidding behavior for subjects “trading up” to obtain the certified food product (a marginally significant effect), it does not affect bids for subjects “trading down” to give up this novel food item. Finally, willingness to pay for safety certified food is large for our respondents—our estimate of the premium is bounded between 37 and 53% of the price of conventional, uncertified food.
