We invited 131 randomly selected firm representatives to three one-day seminars on export promotion. We use the number of randomly invited peers to identify peer effects. We further decompose the invited peers into peers invited to the same seminar, those invited to the earlier seminars, and those invited to the later seminars. We find that the former has a positive effect on firms' participation, whereas the latter two have no significant effect. These results imply that peer effects on participation primarily arise from the benefits of face-to-face interactions. The presence of positive peer effects suggests that multiple equilibria in terms of the share of participants within each village of firms may emerge, which is also consistent with our observations.

This study employs the dataset collected for the assessment of a post-harvest technology project in rural Cambodia and focuses on the heterogeneous preferences of project implementers, frequently overlooked in the literature on programme evaluation studies. We focus on the implementer effect' on the programme participation of the treated farmers. We demonstrate that the heterogeneous programme participation of ordinary farmers could be induced due to heterogeneity in the characteristics of the project staff. In particular, we indicate that the baseline altruism of the project staff, measured by the dictator game, consistently increases the participation rate and the number of participations in the training sessions of beneficiaries. This type of heterogeneity in project staffs' preferences across treatment sites could be a source of treatment heterogeneity for programmes conducted at a certain cluster level. While few studies have focused on the heterogeneity of programme implementers, our empirical results indicate that the preference of implementers could be a source of treatment heterogeneity and imply the importance of implementation of an actual project. - Daichi Shimamoto; Hiroyuki Yamada; Martin GummertFOOD POLICY ELSEVIER SCI LTD 57 135 - 141 0306-9192 2015/11 [Refereed]
Local agricultural markets in developing countries are often characterised as oligopsonistic markets, forcing famers to sell their products below the wholesale price. However, this situation appears to be changing with the diffusion of mobile phones. We investigate how access to market information through mobile phone use affects the selling price of rice in Cambodia. We differentiate the use of mobile phones to obtain market information from household mobile phone ownership. Our results indicate that improved access to market information through mobile phone use is associated with an increase in the selling price of rice. (C) 2015 Elsevier Ltd.

We report the importance of informal training in introducing new post-harvest technologies in rice farming through informal contacts by exploring answers from both in-residence extension workers ('key farmers') and ordinary farmers in rural Cambodia. We use survey data collected in Cambodian villages between December 2012 and January 2013. While in-residence extension workers are well motivated and informal training plays a crucial role, lack of an appropriate financial incentive for the key farmers might hamper the sustainability of the project. We also emphasize that any intervention for rural development must avoid social exclusion and nepotism. Copyright (c) 2015 John Wiley & Sons, Ltd and ERP Environment
