On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk

Willingness-to-pay (WTP) experiments have been widely used to assess demand for a variety of products. Yet can they also generate persistent impacts on adoption and welfare? We answer this question using a randomized controlled trial of a baseline WTP experiment, combined with in-person and phone survey data over a four-year period. We find that a WTP experiment leads to positive and persistent effects on adoption and usage of an improved storage technology, resulting in significantly less pesticide use and fewer storage losses after three years. These results are primarily driven by those households who were able to experience the product. The experiment also leads to positive spillovers on neighbouring households. However, unlike other studies, it does not crowd-in market demand for the product after three years.
