- 22 pages, Many stated preference studies have shown that individuals’ attitudes play an important role in explaining their behaviour and helping to disentangle preference heterogeneity. When responses to attitudinal questions are introduced into discrete choice models, a suitable approach that corrects for potential endogeneity must be adopted. We use a discrete choice experiment to analyse the preferences of residents regarding the use of agri-environmental practices in the peri-urban area of Milan (Italy). A detailed analysis of these preferences is relevant for policymakers as farmers on the peri-urban fringe are often asked to provide environmental services to urban-dwellers. We apply a latent class model that we extend to include indicators of individuals’ attitudes towards the relationship between agriculture and the environment. Besides the application of the control function approach to deal with endogeneity, our main contribution is the use of a refutability test to check the exogeneity of the instruments in the agri-environmental setting. Our results show that attitudinal indicators help to disentangle the preference heterogeneity and that the respondents’ willingness-to-pay distribution differs according to the indicators’ values.

- 18 pages, Government interventions in the agricultural sector have been historically justified by the existence of an income disparity between farmers and non-farmers. However, recent studies have found that such disparity is disappearing over time, particularly in the United States. This work offers the first longitudinal systematic assessment on the average income disparity between farm and non-farm units in the European Union, differentiating between old and new Member States. Using the EU-SILC dataset, both broad (having some farm income) and narrow (living mainly on agriculture) farm households are compared with a general sample of non-farm households and a more restricted sample of self-employed non-farm households. To control for household observable characteristics and time-constant unobserved factors, we use a fixed effects regression. Results suggest that the farm/non-farm income disparity has disappeared in the European Union unless we compare narrow farm households with all non-farm households: in this case, the former are more likely to be better off than the latter. A limited income disparity is found only in the case of new Member States for broad farm households only. Results are used to draw policy implications regarding the role of CAP in supporting farm income.

- Notes:
- 22 pages, Commercialisation of smallholder agriculture is important for rural economic growth. While previous studies have analysed effects of commercialisation on productivity and income, implications for farm household nutrition have received much less attention. We evaluate the effects of commercialisation on household food security and dietary quality with a special focus on calorie and micronutrient consumption. We also examine transmission channels by looking at the role of income, gender, and possible substitution effects between the consumption of own-produced and purchased foods. The analysis uses survey data from farm households in Kenya and a control function approach. Generalised propensity scores are employed to estimate continuous treatment effects. Commercialisation significantly improves food security and dietary quality in terms of calorie, zinc and iron consumption. For vitamin A, effects are insignificant. Commercialisation contributes to higher incomes and increased nutrients from purchased foods, but it does not reduce the consumption of nutrients from own-produced foods. Enhancing market access is important not only for rural economic growth, but also for making smallholder agriculture more nutrition-sensitive.

- 17 Pages., Given the marked heterogeneous conditions in smallholder agriculture in Sub-Saharan Africa, there is a growing policy interest in site-specific extension advice and the use of digital extension tools to provide site-specific information. Empirical ex-ante studies on the design of digital extension tools and their use are rare. Using data from a choice experiment in Nigeria, we elicit and analyze the preferences of extension agents for major design features of ICT-enabled decision support tools (DSTs) aimed at site-specific nutrient management extension advice. We estimate different models, including mixed logit, latent class and attribute non-attendance models. We find that extension agents are generally willing to use such DSTs and prefer a DST with a more user-friendly interface that requires less time to generate results. We also find that preferences are heterogeneous: some extension agents care more about the effectiveness-related features of DSTs, such as information accuracy and level of detail, while others prioritise practical features, such as tool platform, language and interface ease-of-use. Recognising and accommodating such preference differences may facilitate the adoption of DSTs by extension agents and thus enhance the scope for such tools to impact the agricultural production decisions of farmers.

- 24pgs, Increasingly, the health claims made by food products focus on the marketing of specific molecular enrichments. Research exploring consumers’ willingness to pay (WTP) for health claims assumes that individuals hold perfect information on the benefits of the enrichment, and that their valuations depend solely on whether or not they need to improve their health. While health interventions are aimed at individuals at higher health risk, consumers may be unaware of the health risks that they face, limiting the effectiveness of a generic targeting strategy. Using an orthogonal experimental design, we explore the impact of two factors on the WTP for vitamin D enrichment in eggs: whether the information is person-specific or generic; and the presence of a health claim explaining the vitamin D enrichment. Results indicate that it is the provision of information, not the health claim, that influences WTP. Both generic and personalised information lead to similar increases in the WTP for vitamin D enrichment. While we only observe a direct effect of generic information on the WTP for vitamin D enrichment, personal information may also operate by increasing the perceived risk of vitamin D deficiency. Our results support the use of personalised health information during the choice task as a means of increasing the sales of healthy products.

- Notes:
- 15 pages, Increasing popularity of economic experiments for policy impact analysis has led to an on-going debate about the suitability of students to substitute professionals as experimental subjects. To date, subject pool effects in agricultural and resource economics experiments have not been sufficiently studied. In order to identify differences and similarities between students and non-students, we carry out an experiment in the form of a multi-period business management game that is adapted to an agri-environmental context. We compare the compliance behaviour of German agricultural students and German farmers with regard to water protection rules and analyse their responses to two different green nudge interventions. The experimental results reveal that the direction of the response to the policy treatments is similar. Even unexpected behaviour could be reproduced by the student sample. Nevertheless, the magnitude of the treatment effects differed between the two samples. This implies that experimenters in the field of agricultural and resource economics could use the subject pool of students to analyse the direction of nudge policies. If predictions should be made about the magnitude effects, we suggest using a professional subject pool.

- Notes:
- 25pgs, We combine farm accounting data with high-resolution meteorological data, and climate scenarios to estimate climate change impacts and adaptation potentials at the farm level. To do so, we adapt the seminal model of Moore and Lobell (2014) who applied panel data econometrics to data aggregated from the farm to the regional (subnational) level. We discuss and empirically investigate the advantages and challenges of applying such models to farm-level data, including issues of endogeneity of explanatory variables, heterogeneity of farm responses to weather shocks, measurement errors in meteorological variables, and aggregation bias. Empirical investigations into these issues reveal that endogeneity due to measurement errors in temperature and precipitation variables, as well as heterogeneous responses of farms toward climate change may be problematic. Moreover, depending on how data are aggregated, results differ substantially compared to farm-level analysis. Based on data from Austria and two climate scenarios (Effective Measures and High Emission) for 2040, we estimate that the profits of farms will decline, on average, by 4.4% (Effective Measures) and 10% (High Emission). Adaptation options help to considerably ameliorate the adverse situation under both scenarios. Our results reinforce the need for mitigation and adaptation to climate change.
